For number 15, all you need to do is multiply 36 by 25 which gets you 900 square yards. For #16, you would also want to use multiplication, 3 * 39 ($117) , 4 * 15 ($60) and 27 * 2 ($54). Now add them together, 54 + 117 = 171 + 60 = $231. And finally break down the number 309 million, 058 thousand, 304 hundred. Four, eight and, nine need to be in the ones place. So you have 309,058,304, C.
Answer:
see below
Step-by-step explanation:
Using the segment addition postulate
AB + BC = AC
x+2 + 7x-3 = AC
Combine like terms
8x -1 = AC
Using the segment addition postulate
PQ + QR = PR
8y+5 + QR = 13y+25
Subtract 8y from each side
5 + QR = 13y-8y+25
5 + QR = 5y+25
Subtract 5 from each side
QR = 5y+25-5
QR = 5y+20
Answer:

a) $4110
Step-by-step explanation:
Let x represent number of rain coats and C(x) represent total cost to produce new line of rain coats.
We have been given that the fixed costs of $570 to set up for production, and variable costs of $30 per jacket.
The cost of x jackets would be
.
The total cost of x jackets would be variable cost of x jackets plus fixed costs that is $570.
Therefore, the total cost of producing x rain coats would be
.
To find the total cost of producing 118 rain coats, we will substitute
in the above equation as:



Therefore, the total cost of producing 118 rain coats is $4110 and option 'a' is the correct choice.
