Answer:
15x+25 ; 70
Step-by-step explanation:
Given that,
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :
y = 15x+25
For 3 hours,
y = 15(3)+25
= 45 + 25
= 70
So, the required option is (c) " 15x+25 ; 70 ".
Answer:
422
Step-by-step explanation:
Large rectangle
A = 2(lw+wh+lh)
A = 2(7*10+10*5+7*5)
A = 310
Small rectangle
A = 136
Now the squares that connect both, 4*3
Since you have 1 on each rectangle, the total area for this is 24
add 310 + 136 and substract 24
The answer would be 26 because you're multiplying .5 times 52
There are 8 equal parts. Each part is 1/8 of the whole 8/8
