the answer is 15cm (pls mark brainlest)
Answer:
3:40
Step-by-step explanation:
We need both measurements in the same units.
1 m = 100 cm
2 m = 2 × 1 m = 2 × 100 cm = 200 cm
15 cm to 2 m = 15 cm to 200 m
Divide both numbers in the ratio by 5 cm.
15 cm to 200 cm = 3:40

Step-by-step explanation:
todd Has a collection of 8cds and sally has a collection of 18 cds Todd is adding 9cds a month to his collection while sally is adding 7 cds a month to her collection when will they have the same number of cds and how many will they have
Answer:
Step-by-step explanation:
Let's create some equations first.
Say M = number of months, T = Todd and S = Sally.
We know that Todd starts with 8 cds and sally starts with 18 cds.
This means when M= 0, T = 8 and S = 18
After one month (M = 1), Todd adds 9 cds.
This means can write the following equation:
T = 8 + 9M
So after the first month (where M = 1), we can find out that Todd has
T = 8 + 9 x 1 = 8 + 9 = 17 cds
For Sally, we know she adds 7 cds per month.
S = 18 + 7M
After one month (M = 1),
S = 18 + 7 x 1 = 25 cds.
Now we are trying to find when they will have the same number of cds and how many.
This means we are trying to figure out what M = ? when Todd and Sally are equal.
So we want to find when T = S
Remember, earlier we wrote :
T = 8 + 9M
S = 18 + 7M
If T = S, this means:
8 + 9M = 18 + 7M
Gather the like terms and solve for M.
Subtract 8 from both sides.
9M = 10 + 7M
Subtract 7M from both sides
2M = 10
Divide both sides by 2
M = 5.
So in 5 months, we are saying T = S (Todd and Sally will have the same number of cds).
Put M = 5 back into our earlier equations to find out how many cds they have after 5 months.
T = 8 + 9M
T = 8 + 9 x 5
T = 53
Therefore, after 5 months Todd and Sally will have 53 cds each :)
Need help with geometric series'!
Please include a step by step explanation.
Answer:
[tex] - 13107[/tex]
Step-by-step explanation:
We would like to evaluate the following Geometric Series ,
[tex]\displaystyle\longrightarrow \sum _{n=1}^8 (-4)^{n-1 }[/tex]
In a geometric series, a common number is multiplied to the previous term in order to find the next term . And that common number is called common ratio (r) .
As we know that ,
[tex]\displaystyle\longrightarrow \sum_{x = 1}^n f(x) = f(1) + f(2) + \dots + f(n) [/tex]
So , we can write the series as ,
[tex]\displaystyle\longrightarrow (-4)^{1-1}+(-4)^{2-1}+\dots +(-4)^{8-1} [/tex]
Simplify,
[tex]\displaystyle\longrightarrow (-4)^0 + (-4)^1+(-4)^2+\dots +(-4)^7 [/tex]
We can find the common ratio by dividing and successive term by its preceding term , as ;
[tex]\displaystyle\longrightarrow r =\dfrac{-4}{1}=-4 [/tex]
Again , here ;
First term = a = [tex](-4)^0=1[/tex]Common ratio = [tex]-4[/tex]number of terms (n) = 8And we can find the sum of geometric series using the formula , ( this is used when the value of r is less than 1 , here it is -4 ) .
[tex]\displaystyle\longrightarrow \Bigg[ Sum = \dfrac{a(1-r^n)}{1-r}\Bigg] [/tex]
where the symbols have their usual meaning.On substituting the respective values, we have;
[tex]\displaystyle \longrightarrow\rm{ Sum }=\dfrac{ 1\{1-(-4)^8\}}{1-(-4)}\\ [/tex]
Simplify ,
[tex]\displaystyle\longrightarrow \rm{Sum} = \dfrac{1-65536}{1+4}\\[/tex]
[tex]\displaystyle\longrightarrow \rm{Sum} = \dfrac{-65535}{5} [/tex]
Simplify by dividing ,
[tex]\displaystyle\longrightarrow \underline{\underline{ \rm{Sum} = -13107}} [/tex]
And we are done !
Select all the true statements. Triangle A B C where the measure of angle A is 2 x plus 1 degree, angle B is x degrees, and angle C is x plus 15 degrees. Group of answer choices m∠C = 56 From smallest to largest: ∠B, ∠C, ∠A m∠A = 99 x = 49 (4x + 16) = 180
Answer:
[tex]B= 41[/tex]; [tex]C = 56[/tex]; [tex]A = 83[/tex]
Step-by-step explanation:
Given
[tex]A = 2x + 1[/tex]
[tex]B = x[/tex]
[tex]C = x + 15[/tex]
Required
Arrange the angles from smallest to largest
First, we need to determine the value of x.
Since, it is a triangle:
[tex]A + B + C = 180[/tex]
Substitute values for A, B and C
[tex]2x + 1+ x + x + 15 = 180[/tex]
Collect Like Terms
[tex]2x + x + x = 180 - 15 -1[/tex]
[tex]4x = 164[/tex]
Solve for x
[tex]x= 164/4[/tex]
[tex]x= 41[/tex]
Solve for A, B and C
[tex]A = 2x + 1[/tex]
[tex]A = 2 * 41 + 1[/tex]
[tex]A = 82 + 1[/tex]
[tex]A = 83[/tex]
[tex]B = x[/tex]
[tex]B= 41[/tex]
[tex]C = x + 15[/tex]
[tex]C = 41 + 15[/tex]
[tex]C = 56[/tex]
From Smallest to Largest, we have:
[tex]B= 41[/tex]; [tex]C = 56[/tex]; [tex]A = 83[/tex]

Line t passes through points (9, 10) and (3, 3). Line u is parallel to line t. What is the slope of
line u?
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Step-by-step explanation:
a parallel line has the same slope. that is the actual meaning of "parallel".
so we need to find the slope of line t to get our answer.
remember, the slope is the ratio " y coordinate change / x coordinate change" when going from one point on the line to another.
so, here we have 2 points (9, 10) and (3, 3).
going from the first to the second we see
x changes by -6 (from 9 to 3).
y changes by -7 (from 10 to 3).
the slope is then -7/-6 = 7/6.
and therefore, the slope of u is also 7/6.

Find the range of the data. 133,117,152,127,168,000,000
Answer:
168
Step-by-step explanation:
168 would be the range because the range is the highest number - the lowest number so 168=highest and 000=lowest
so 168-000 or just0=168
here's some extra answers.
The mean=100 rounded up to nearest 100
Mean= the average of the data set.
Median=127
The median is the middle number when the numbers in the data set are sorted least to greatest.
Mode=000 or just 0
The mode is the number that appear the most in the data set and 000 or just 0 appears twice rather than,all the other numbers only appear once.
Minimum=000 or just
The minimum is the lowest number in the data set and as for this one is is 0.
Maximum=168
The maximum is the highest number and the data set and 168 is the highest in this one.

Kilani and Adrian are starting a nutrition program. Kilani currently consumes 1200 calories a day and will increase that number by 100 calories each day. Adrian currently consumes 3230 calories a day and will decrease that number by 190 each day. They will continue this pattern until they are both consuming the same number of calories per day. In how many days will that be? Be sure to define your variables, write an equation, and answer the question in context.
Answer:
7 days
Step-by-step explanation:
Let us represent the number of days = a
Kilani currently consumes 1200 calories a day and will increase that number by 100 calories each day.
1200 calories + 100 calories × a
1200 + 100a
Adrian currently consumes 3230 calories a day and will decrease that number by 190 each day.
3230 calories - 190 calories × a
3230 - 190a
The number of days that they would be consuming the same number of calories =
Kilani = Adrian
1200 + 100a = 3230 - 190a
Collect like terms
190a + 100a = 3230 - 1200
290a = 2030
a = 2030/290
a = 7 days
Therefore, the would be consuming the same number of calories in 7 days

How wide is each annual ring (springwood and summerwood combined)? Disregard the bark and pith in your calculations. Show your work. Write your answer in inches
The width of each ring in the redwood trees of coastal California is 0.06 inches.
How to estimate the width of a ring in a tree
According to the statement, we know that age of a tree and base diameter are directly proportional to the number of rings. The width of the ring is estimated by dividing the radius of the tree base by the age of the tree:
[tex]w = \frac{10\,ft \times 12\,\frac{in}{ft} }{2000}[/tex]
[tex]w = 0.06\,in[/tex]
The width of each ring in the redwood trees of coastal California is 0.06 inches. [tex]\blacksquare[/tex]
Remark
The statement in incomplete, correct form is shown below:
Each year of its life, a tree grows a new ring just under the outside bark. The new ring consists of two parts, light-colored springwood, when the tree grows the fastest, and a darker-colored summerwood, when growth slows. When conditions are good and there is lots of sun and rain, the new ring is thicker than the rings formed when there is drought or excessive cold. At the center of the tree is a dark circle called pith that is not connected to the age of the tree.
The redwood trees of coastal California are the tallest living things on earth. On redwood is 350 feet tall, 20 feet in diameter at its base, and around 2000 years old. Assume that the lower 50 feet of the tree form of the tree form a cylinder 20 feet in diameter and that all of the rings grew at the same rate.

bobby's cat runs x mph. bobby's dog runs twice as fast as his cat. if the cat and the dog start running away from each other, how far away from each other will they be after 30 minutes
Answer:
They will be 0.5x miles away from each other.
Calculation of the distance:
Since Bobby's cat runs x mph. Bobby's dog runs twice as fast as his cat.
So here the speed of the dog should be 2x
Now we know that
Here distance of cat should be x of 30 minutes or half hour = 0.5x miles
And, Distance of dog should be 2x of 0.5 = x miles
So, the difference should be
= x - 0.5
= 0.5x miles
hence, They will be 0.5x miles away from each other.
Step-by-step explanation:
Answer:
1.5x miles, because you already know that the cat's speed is 0.5x miles, and the dog is x miles, so when you add it together, you get 1.5x miles

4x + 6y + -3 = 0
Reorder the terms:
-3 + 4x + 6y = 0
Solving
-3 + 4x + 6y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 4x + 3 + 6y = 0 + 3
Reorder the terms:
-3 + 3 + 4x + 6y = 0 + 3
Combine like terms: -3 + 3 = 0
0 + 4x + 6y = 0 + 3
4x + 6y = 0 + 3
Combine like terms: 0 + 3 = 3
4x + 6y = 3
Add '-6y' to each side of the equation.
4x + 6y + -6y = 3 + -6y
Combine like terms: 6y + -6y = 0
4x + 0 = 3 + -6y
4x = 3 + -6y
Divide each side by '4'.
x = 0.75 + -1.5y
Simplifying
x = 0.75 + -1.5y
