Answer:
B
Step-by-step explanation:
We simply find the area and then multiply that by $1.5 to get our answer.
We need to break down the composite figure and add up each individual area to get total area.
To the right, we will have a trapezoid with bases:
base 1 (top) = 31 - 9 = 22
base 2 (bottom) = 12 (given)
and
height = 9 + 3 = 12
Putting into trapezoid area formula we have:

Also, the left side, we have a skinny rectangle with height 3 and length 9. Thus, the area is:
3 * 9 = 27
Total area is 204 + 27 = 231
Each square feet is $1.50, hence total cost = 231 * 1.5 = $346.50
B is the right answer.
Answer:
9 days.
Step-by-step explanation:
We first subtract the amount already done from the total needed.
<em>10 - 1 = 9.</em>
Next, we take the remainder and divide it by the amount being made per day to get our final answer.
<em>9 / 1 = </em><em>9</em>.
The answer is 9 days.
What are you trying to solve for?
Step-by-step explanation:
then let's transistors this into mathematical symbols :
9 times a number y
9×y or simply 9y
subtracted from 85
85 - ...
is seven times
= 7 × ...
the sum of four and y
(4 + y)
together this is then
85 - 9y = 7 × (4 + y)
and just FYI : let's solve this
85 - 9y = 7×4 + 7y = 28 + 7y
85 = 28 + 16y
57 = 16y
y = 57/16 = 3.5625
