A health insurance payment of $34.55 was deducted from ms. Donaldson's earnings for the week. After the insurance deduction, pay
leonid [27]
I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10

So the 34.55 were deduced from this number, and the remaining amount was:

907.10-34.55=872.65

After this, further 28% were deduced, which means that 100-28=72% were left.

And this is:72%*872.55= 628.236 (which we round to 628.24!)

Find the area of the figure. Use 3.14 for pie . Round your answer to the nearest tenth.
gizmo_the_mogwai [7]

Answer:

538.3

Step-by-step explanation:

First of all find the area of the rectangle

L*W

15*30

450

Now find the area of semi circle

1/2\pi r^{2}

Since radius is half a diameter divided 15 by 2=7.5

1/2\pi 7.5^{2}                            7.5 times 7.5= 56.25

1/2*3.14*56.25

56 times 3.14 is 176.625 now multiply 176.625 by 1/2

Answer is 88.3125

Now add 450 to 88.3125

Final answer: 538.3125

Which rule can be used to describe the growth of the y vales of the function y=12^x over each interval from x=-1 to x=3?
valentinak56 [21]
The function is f(x)=12^x. 

This means that as we get from 1 to 2, we have the following values:

f(1)=12^1=12, and f(2)=12^2=12\cdot12.

Similarly, if we check x=3, we have f(3)=12^3=12\cdot12\cdot12.


We can see that as x changes by 1 (with greater values), y increases by a factor of 12.


Answer: multiply by 12
