A baker decorates 42 cupcakes in 30 minutes. She decorates cupcakes at a constant rate.

Answers

Since the baker can bake 42 cupcakes in 30 minutes, and we need to find how many she can decorate in 1 min, we divide the 30 min by 30 to get 1 min, and divide 42 by 30 as well since it is a constant rate and we need to keep it proportional. 42/30 is 1.4, so she can decorate 1.4 cupcakes in 1 min. Hope this helps!

a wildlife manager determines that the function y=200x1.07* represents the deer population at a state park x years after the population is first counted. what is the population after 12 years? what is the initial population? what is the percentage rate? complete the table below.

Answers

Answer:

Table:

0,200

4, 262

8,344

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?

B. after how many times will rachel be able to make her desert in 63 minutes?

C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?

Answers

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

Add all the sides for perimeter

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281

Function (f) is defined by the equation f(x)=3x-7. Find the value of c so that f(c) =20 is true.

Answer: C=9

The value of c so that the function f ( c ) = 20 is when c = 9

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

f ( x ) = 3x - 7

Now , substituting the value of f ( x ) = 20 , we get

when x = c

f ( c ) = 3c - 7

The value of the equation f ( c ) = 20

Substituting the value in the equation , we get

3c - 7 = 20

On simplifying the equation , we get

Adding 7 on both sides of the equation , we get

3c = 27

Divide by 3 on both sides of the equation , we get

c = 9

Therefore , the value of the variable c = 9

Hence , The value of c so that the function f ( c ) = 20 is when c = 9

Which statement about the picture below is true

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

sum = (360)(8) = 2880°
sum = (360)(10) = 3600°
sum = (180)(8) = 1440°
sum = (180)(10) = 1800°

Answers

Correct answer is:

1800°
the correct answer is 1440.

The equation to find the sum of interior angles in a polygon is s = 180(n-2), n being the amount of sides and s being the sum. To solve you would do s = 180(10-2), s = 180(8), and s = 1440. hopefully that makes sense haha. use the equation s=180(n-2) :))
