Search up your question online before posting it here, it probably has been solved before

7/40 a day means that Shara works (7/40)*24=4.2 hours a day.

Multiplying 4.2 by 7, we get 29.4 hours per week, so Shara works 29.4 hours per week

Saul works 7/80 week each week

There are 168 hours in a week, so we multiply 7/80 by 168 to get 14.7 hours per week

Shara works more than Saul each week

Shara works 29.4 hours a week and Saul works 14.7 hours a week

Let me know if I did anything wrong

3a - 15 = 6

Add 15 to both sides to cancel out the 15 on the left side

3a = 21

Divide 21 by 3

a = 7

\(10-k^3\)

The angle will still be the same, no matter what size, so z is still 34 degrees.

Notice that 9 and 5 are the only measurements that stay. 

To find the proportion (idk if thats the right word) between the two triangles, we make a fraction, \(\frac{5}{9}\). We do this so that we can figure out the lengths of each side by multiplying and/or dividing.

To find y, we multiply 18 by \(\frac{5}{9}\), getting 10, so y is 10.

To find x, we have to DIVIDE 8 by \(\frac{5}{9}\), since unlike y, x is on the left triangle.

8 divided by \(\frac{5}{9}\)is 14.4, so x is 14.4.

So the final answer is:

x = 14.4

y = 10

z = 34 degrees

We can solve this by subtracting the area of the driveway from the entire rectangle

The area of a rectangle is \(lw\), so multiplying 14 by 32, we get 448

Now we need to find the area of the driveway. We can split up the driveway into 2 rectangles, one big rectangle at the left and a tiny rectangle in the upper right.

To find the area of the big rectangle in the driveway, we multiply 10 by 20, getting 200.

To find the area of the tiny rectangle in the driveway, we subtract 20 from 26 to find the length, which is 6.

Now we need to find the width of the tiny rectangle. We can do this by subtracting 7 from 10, getting 3.

Multiplying 6 by 3, we get 18, so the area of the tiny rectangle is 18.

Adding 200 to 18, we get 218, so the area of the driveway is 218 ft squared.

Now we need to subtract 218 from 448.

448-218=230

So the answer is 230 ft squared
