the area of a rectangle is
length × width
the 2 walls are 2 rectangles.
15 3/4 × 10
13 1/2 × 10
to be sure, let's convert both mixed numbers to full fractions :
15 3/4 = (15×4 + 3)/4 = 63/4
13 1/2 = (13×2 + 1)/2 = 27/2
so, the areas are
63/4 × 10 = 630/4 = 315/2 ft²
27/2 × 10 = 270/2 ft²
in total that is
315/2 + 270/2 = 585/2 = (584/2 + 1)/2 = 272 1/2 ft²

What is meant by interest?The sum that must be repaid for a loan or the sum that is collected in exchange for a loan is known as interest. Principal is the term used to describe borrowed or lent funds. The total of the principal plus interest is referred to as the Amount. Rate of Interest refers to the amount at which interest is calculated on the principal. A percentage of the principle is how interest is most commonly computed. For instance, if you agreed to borrow $100 from a friend with 5% interest and repay it over time, the interest you would have to pay would simply be 5% of $100, or $5.Let
CD's = x
Bonds = x + 60000
Stocks = y
x + x + 60000 + y = 140000 ----> 2x + y = 80000 .......(1)
Using I = Prt; t = 1; I = Pr
2x + 3.7(x + 60000) + 11.1y = 7800(100× ) × Since I used an exact proportion, the opposite side needs to be multiplied by 100.
5.7x + 11.1y = 558000 .......(2)
Either elimination or substitution;

The linear function relationship between the change in the median home value and the year, indicates that we get;
a) The home values increased at a higher rate in Connecticut
b) The median home value in West Virginia in 2010 is $80,721
c) The home values in both states are equal in 1915
What is a linear function relationship?A linear function relationship can be expressed in the form; y = m·x + c. Where, m is the slope of the graph of the function and c is the y-intercept.
a) The rate of increase of the home value, where the values of the house change linearly can be found as follows;
Rate of change of home value for West Virginia = [tex]\frac{72800-33200}{200-1950} = 792[/tex]
The home values in West Virginia increases by about $792 per year
Rate of change of home values for Connecticut = [tex]\frac{166900-71900}{2000-1950} =1900[/tex]
The home values in Connecticut increases by $1900 each year
Therefore;
The state that have home values increase at higher rate is Connecticutb) The increase in the home value in West Virginia per year is $792, therefore, the home value in 2010 can be found as follows;
The number of years between 2010 and 2000 = 2010 - 2000 = 10
Home value in 2010 = Home value in 2000 + 792 × 10
Home value in 2010 = $72800 + $792 × 10 = $80720
Home value in 2010 in West Virginia = $80720c) The equation for the median home value for West Virginia can be presented as follows;
y - 33200 = 792×(x - 1950)
y = 792×(x - 1950) + 33200
The equation for the median home value for Connecticut can be presented as follows;
y - 71900 = 1900×(x - 1950)
y = 1900×(x - 1950) + 71900
When the home values in West Virginia is equal to the home value in Connecticut, we get;
792 × (x - 1950) + 33200 = 1900 × (x - 1950) + 71900
1900·x - 792·x = 1900 × 1950 - 792 × 1950 + 33200 - 71900 = 2121900
1108·x = 2121900
x = 2121900/1108 ≈ 1915.07
The year the median value will be the same in both states is about 1915

Round relative frequencies to 3 decimal places. Class Boundaries Frequency Relative Frequency 54.5 - 63.5 72.5 olan 81.5 90.5
The shape of this histogram is skewed to the right since the highest frequency is found in the first class, and the frequencies decrease as the numbers increase.
The class width, also known as the class interval, is the difference between the upper and lower boundaries of a class. In this frequency distribution, the class width is 9 since the lower boundary of the first class is 54.5 and the upper boundary of the last class is 90.5. We can calculate the frequency of each class by counting how many numbers fall within the class boundaries. For example, the first class has 72 observations since there are 72 numbers that fall between 54.5 and 63.5. To calculate the relative frequency of each class, we divide the frequency of each class by the total frequency. For example, the relative frequency of the first class is 0.312 since 72/231 = 0.312. Once the frequencies and relative frequencies have been calculated, a histogram can be made to represent the data. The shape of this histogram is skewed to the right since the highest frequency is found in the first class, and the frequencies decrease as the numbers increase.

The post-neonatal mortality rate for the year is 1.1×10⁻⁷.
What is the post-neonatal mortality rate?The post-neonatal mortality rate in a year is applicable when the death day lies between 28 and 364. First, divide the number of post-neonatal deaths by the number of live births. Then multiply the obtained value by 1000 to get the post-neonatal mortality rate.
It is known that 1 billion units = 10⁹ units. So, 20 billion live births will be 20×10⁹ live births. Also, the number of post-neonatal deaths is 2200.
So, use the formula, post-neonatal mortality rate = (the number of post-neonatal deaths)/(the number of live births).
post-neonatal mortality rate = 2200/(20×10⁹)
= 110×10⁻⁹
= 1.1×10⁻⁷
Therefore, the obtained answer is 1.1×10⁻⁷.

On Monday, he made 7 cakes. On Lionel makes cakes for the bake sale.
On Monday, he made 7 cakes. On Tuesday, he works an additional 2 hours and has a total of 13 cakes.
Determine how many cakes he makes in one hour. Tuesday, he works an additional 2 hours and has a total of 13 cakes.
Determine how many cakes he makes in one hour.
To determine how many cakes Lionel makes in one hour, we can use the following formula:
cakes per hour = total cakes / total hours worked
On Monday, Lionel made 7 cakes in some number of hours, so we don't know how many cakes he made per hour that day. However, on Tuesday, he made an additional 6 cakes (13 total cakes - 7 cakes made on Monday), and he worked for 2 hours longer than he did on Monday. Therefore:
cakes per hour on Tuesday = 6 cakes / 2 hours = 3 cakes per hour
So Lionel made 3 cakes per hour on Tuesday. We don't have enough information to determine how many cakes he made per hour on Monday.
According to the Quotient Remainder Theorem, for every integer n and positive integer d, there exist integers q and r such that n=dq+r, 0≤r
Let n be your 8-digit student identification number (ID) and let d
be the leftmost three digits of your student ID. For example, if your student ID was 12034567 , then n=12,034,567 and d=120. Find q and r as required by the Quotient Remainder Theorem using n and d constructed from your student ID.
Divide the 8-digit student ID by the leftmost 3 digits to find q and r using the Quotient Remainder Theorem. If your 8-digit student ID is 12345678, then d = 123, n = 45,678, q = 371, and r = 45.
Suppose your 8-digit understudy ID is 12345678. Then, at that point, we can take the furthest left three digits to get d = 123. Also, we can take the excess 5 digits to get n = 45,678.
To find q and r, we can utilize the condition n = dq + r and address for q and r.
To begin with, we really want to see as the biggest various of d that is not exactly or equivalent to n. We can do this by separating n by d and taking the floor of the outcome:
q = ⌊n/d⌋ = ⌊45,678/123⌋ = 371
Then, we can track down the rest of taking away the result of d and q from n:
r = n - dq = 45,678 - 123 × 371 = 45,678 - 45,633 = 45
Along these lines, in the event that your 8-digit understudy ID is 12345678, d = 123, n = 45,678, q = 371, and r = 45.
The Remainder Leftover portion Hypothesis expresses that for any whole number n and positive whole number d, there exist whole numbers q and r with the end goal that n=dq+r, where q is the remainder and r is the rest of. We can track down q and r by separating n by d and taking the floor of the outcome for q, and deducting the result of d and q from n for r.

A scientist is studying wildlife. She estimates the population of bats in her state to be 345,000. She predicts the population to grow at an average annual rate of 1.2%. Using the scientist’s prediction, create an equation that models the population of bats, y, after x years.
y=345,000(0.012)^x
y=345,000(0.988)^x
y=345,000(1.012)^x
y=345,000(1.2)^x
Answer:
Step-by-step explanation:
The equation that models the population of bats, y, after x years can be found using the formula:
y = P(1 + r)^x
where P is the initial population, r is the annual growth rate as a decimal, and x is the number of years.
In this case, the initial population P is 345,000, the annual growth rate r is 1.2% or 0.012 as a decimal, and x is the number of years. Substituting these values into the formula, we get:
y = 345,000(1 + 0.012)^x
Simplifying the expression in the parentheses, we get:
y = 345,000(1.012)^x
Therefore, the equation that models the population of bats, y, after x years is:
y = 345,000(1.012)^x
Step-by-step explanation:
the other answer is correct.
I just want to point out some mechanism used here :
the increase by 1.2%
an increase by x% means adding x% to the original 100%.
so, we end up with (100 + x)%.
"%" just stands for 1/100.
so, if y = 100%, an increase by x% is
y×(100 + x)/100 = y×(1 + x/100)
in our case here that is
345,000 × (1 + 0.012) = 345,000 × 1.012
and since the increase rate of 1.2% applies per year, we multiply the end population of every year by 1.012 for the following year.
so, each year a new factor of 1.012 is being integrated into the calculation.
it goes then
345,000×1.012×1.012×1.012×...×1.012 x times after x years.
and we get
y = 345,000 × (1.012)^x

it is not advisable to make only the minimum payment on a credit card if Jason wants to minimize the amount of interest he has to pay and pay off his debt faster.
What is Credit card?A credit card is a payment card issued to users to enable the cardholder to pay a merchant for goods and services based on the cardholder's accrued debt.
Jason may not be doing the right thing by making only the minimum payment on his credit card, depending on the interest rate and penalty charges.
When a credit card holder makes only the minimum payment, the remaining balance accrues interest, which is added to the principal amount.
This means that the total amount owed on the credit card increases every month, even if no additional purchases are made.
The interest rate charged by the credit card company can significantly impact how much Jason ends up paying over time.

What is properties of multiplication and addition?Properties of addition and multiplication are defined for the various conditions and rules of addition and multiplication. The properties are:
Commutative propertyAssociative Property Distributive Property Identity Propertyab² • 0 = 0The product between any number and this one is zero. This comes from the existence of zero, which states that there must exist a value that represents nothingness, the zero.
(7 + 5) + 1 = 7 + (5 + 1)This is the associative property of addition,
6 = 6This is the reflexive property of equality, which says that every number is equal to itself.
7(x-3) = 7x - 21This is the distributive property of addition which says ,
C*(A + B) = C*A + C*B
x + (-x) = 0This is the inverse property of addition, this property says that for any real number x there exists a real number -x such that x+(-x)=0.
if y = 3, then 3 = yThis is the symmetric property.
if x = -1, and -1 = z, then x = zThis is the transitive property, we can apply it in the next way
then x = z
4x • 1 = 4xThis is the identity property of multiplication.
(a+b) + 0 = (a+b)This is identity property of addition is that when a number n is added to zero, the result is the number itself i.e. n + 0 = n.
3 • 1/3 = 1This is inverse property of multiplication. It states that if you multiply a number by its reciprocal, also called the multiplicative inverse, the product will be 1
Hence, the properties are identified.

Jana is wondering about the probabilities of genetic crosses. She knows that
when her gerbil had babies, there was a 50% chance of babies being male
and a 50% chance of being female. Her gerbil gave birth to 6 babies, and 4
were girls and 2 were boys. Why weren't they 50% male and 50% female?
Experimental Probability
Just because the odds are 50% for both genders doesn't mean there is any reason for it to be even. It's like flipping a coin six times. there's no reason for it to land on tails 3 times and heads 3 times. Its just more likely

Tamika leans a 30-foot ladder against a wall so that it forms an angle of 65∘ with the ground. How high up the wall does the ladder reach? Round your answer to the nearest hundredth of a foot if necessary.
Answer:
64.34 feet.
Step-by-step explanation:
To solve this problem, we can use trigonometric ratios, specifically the tangent ratio.
Let's denote the height up the wall that the ladder reaches as "h". We can then set up the following equation:
tan(65°) = h/30
To solve for h, we can multiply both sides by 30:
30 tan(65°) = h
Using a calculator, we can find that tan(65°) is approximately 2.1445. Multiplying this by 30 gives us:
h ≈ 64.34 feet
Therefore, the ladder reaches approximately 64.34 feet up the wall. Rounded to the nearest hundredth of a foot, the answer is 64.34 feet.
-3 (3b + 6) = 36 - 3b
Answer:
b = -9
Step-by-step explanation:
-3 (3b + 6) = 36 - 3b
-9b - 18 = 36 - 3b
-6b - 18 = 36
-6b = 54
b = -9
Let's check
-3(3(-9) + 6) = 36 - 3(-9)
-3( -27 + 6) = 36 + 27
-3( -21) = 63
63 = 63
So, b = -9 is the correct answer.
Step-by-step explanation:
-3(3b+6)=36-3b
-9b-18=36-3b
-9b+3b=36+18
-6b=54
divide both sides by -6
b= -9
