Answer:
Step-by-step explanation:
At = 2*(h×w + h×l + w×l)
= 2*(4.8×3.1 + 4.8×7.2 + 3.1×7.2)
= 2*(14.88 + 34.56 + 22.32)
= 2*71.76
= 143.52 cm²
Answer:
<h2>The slope is 100</h2>
Step-by-step explanation:
Given that the equation that represents the total cost is given as
C=900+100p--------1
this equation is the same as the equation of a straight line, and we can deduce from it when we compare it the straight line equation
the equation of a line is given as
y=mx+c------2
comparing equation 1 and 2 we have the slope as
m=100
In the context of this problem m=100 means that the cost of producing a phone per material and labour cost is $100
