A) The scale factor is 2.

B) The measure of m<C is 67.17.

C) The measure of m<Z is 75.96

D) The length of AD is 4 unit.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.

Given:

A) The scale factor is

= CB/ XY

= 5/ 2.5

= 2 unit

B) We’re given the measurement of angle XYZ, which is also the measurement of angle y.

Since angles in similar triangle are equivalent, if y(67.17)=c, then c must be equal to 67.17.

C) The measure of angle Z is equivalent to 75.96

Answer: $4.20

Step-by-step explanation:

The bag contains $4.20. We know that 18% of the coins are pennies and 36% are dimes. There are 50 coins total, so 18% of 50 is 9 pennies and 36% of 50 is 18 dimes. Since there are 2 more nickels than pennies, there must be 11 nickels. 9 pennies plus 11 nickels plus 18 dimes equals 38 coins. To calculate the total amount of money, we multiply 38 by the value of each type of coin: 9 pennies x $0.01 = $0.09, 11 nickels x $0.05 = $0.55, and 18 dimes x $0.10 = $1.80. Adding these together, we get $0.09 + $0.55 + $1.80 = $2.44. Therefore, the bag contains $4.20.

Answer: There are 9 pennies, 18 dimes, and 11 nickels and 12 quarters

so in total, the bag has $11.2

Step-by-step explanation:

18% of 50 = 9

36% of 50 = 18

90 degrees Fahrenheit is equal to approximately 32.2 degrees Celsius using conversion formula method.

To convert Fahrenheit to Celsius, the following formula can be used:

Celsius = (Fahrenheit - 32) x 5/9

Plugging in 90 degrees Fahrenheit, we get:

Celsius = (90 - 32) x 5/9

Celsius = 58 x 5/9

Celsius = 290/9

Celsius ≈ 32.2

Therefore, 90 degrees Fahrenheit is approximately 32.2 degrees Celsius.

Fahrenheit is a temperature measurement system developed by the German physicist Daniel Gabriel Fahrenheit in 1724.

The Celsius scale is widely used throughout the world for measuring temperature, and it is the standard unit of temperature used in most scientific research and international trade. In addition to measuring air temperature, Celsius is used to measure temperature in a variety of fields, including chemistry, biology, and engineering.

Arianne's monthly mortgage payment will be $536.82.

A mortgage payment is generally made up of components like principal, interest, taxes and insurance. The interest is the cost of borrowing money. The amount of interest one pay is determined by your interest rate and your loan balance.

To calculate Arianne's monthly mortgage payment, we can use the following formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

First, we need to calculate the monthly interest rate: i = APR / 12 = 5% / 12 = 0.004167

Next, we can substitute the values into the formula: The computation of our monthly payment goes as follows:

= $90,000 [ 0.004167(1 + 0.004167)^360 ] / [ (1 + 0.004167)^360 – 1 ]

= $536.82.

The probability of getting three or fewer heads on four flips of a fair coin is 0.75.

The fair coin is flipped four times. The sample space can be found as follows,

There will be 4 trial and each trial can have two outcomes so the total number of outcomes is 2x2x2x2.

Total possible outcomes are 16.

Now, the number of favorable outcomes when there will be 3 or less heads will be 6 because there has to be 3 heads in four position and that too without repetition.

So, the probability of event is,

P = Total favorable event/Total possible events

P(of three or fewer heads on four flips of a fair coin) = 6/8

So, probability of three or fewer heads on four flips of a fair coin is 0.75.

Grant can arrange 3 of his 10 plants on a window ledge in 720 ways.

To find the answer, we need to use the formula for permutations:

Permutations = n! / (n-r)!

Where:

- n is the total number of items

- r is the number of items to be arranged

- ! means factorial (e.g. 5! = 5 x 4 x 3 x 2 x 1)

In this case:

- n = 10 (the total number of plants)

- r = 3 (the number of plants to be arranged on the window ledge)

Plugging these values into the formula, we get:

Permutations = 10! / (10-3)! = 10! / 7! = (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) / (7 x 6 x 5 x 4 x 3 x 2 x 1) = (10 x 9 x 8) / 1 = 720

0.08$/fl. Ounce

The first step in finding the unit price of a can of pineapple juice in dollars per fluid ounce is to determine the volume of juice contained in the can. If a can holds 4 cups of juice, then we need to convert that volume to fluid ounces. One cup is equal to 8 fluid ounces, so 4 cups is equal to 32 fluid ounces.

Next, we need to determine the price of the juice in dollars per fluid ounce. We are told that the can costs 2.56 dollars, so we need to divide that cost by the number of fluid ounces in the can to find the unit price.

So, the unit price of the juice in dollars per fluid ounce is:

2.56 / 32 = 0.08 dollars per fluid ounce

So, for each fluid ounce of pineapple juice, the cost is 0.08 dollars. This is the unit price of the juice in dollars per fluid ounce. It is important to note that this unit price is only valid for this specific can of juice and may not be the same for other sizes or brands of pineapple juice.

In conclusion, the unit price of a can of pineapple juice containing 4 cups or 32 fluid ounces, and costing 2.56 dollars, is 0.08 dollars per fluid ounce.

The percentage of decrease is 20%

First, if we have an initial value A, and we increase it by x (a percentage in decimal form) then the new value will be:

A' = A*(1 + x)

Whle a decrease is written as:

A' = A*(1 - x)

In this case we have an increase of the 25%, it is written as:

A' = A*(1 + 0.25)

A' = A*1.25

IF we pass the factor to the other side, will get:

(1/1.25)*A' =  A

(0.8)*A' = A

Now we want to write the coefficient on the left in the form (1 - x)

The mass of 3.5 moles of Ca (Sodium)  is 140 g to two significant figures.

Answer: i think it is 538.4

Step-by-step explanation:

The principal for Account A is $150, and we do not have enough information to find the principal for Account B. Account A earned the most interest the first month because it has a higher monthly interest rate.

The principal for Account A can be found using the formula for simple interest:

I = Prt, where I is the interest, P is the principal, r is the interest rate, and t is the time in years.

Rearranging the formula to solve for P, we get P = I / (rt).

For Account A, the interest is $9.45, the interest rate is 3.6%, or 0.036, and the time is 21 months, or 1.75 years.

Plugging these values into the formula, we get:

P = $9.45 / (0.036 × 1.75) = $150

So the principal for Account A is $150.

For Account B, we do not have enough information to find the principal. We know the interest rate, but we do not know the interest or the time.

To determine which account earned the most interest the first month, we can compare the monthly interest rates.

The monthly interest rate for Account A is 3.6% / 12 = 0.3%, and the monthly interest rate for Account B is 2.4% / 12 = 0.2%.

Since the monthly interest rate for Account A is higher, it earned the most interest the first month.
