Answer:
Step-by-step explanation:
We are given the following in the question:
The length of the pen will be 5 feet more than twice as long as the width of the pen.
Let y be the length and x be the width. Thus, we can write:
Fencing = Perimeter of rectangular pen
The cost of the pen will be $7.50 per foot of fencing.
Total Cost of fencing =
is the required cost function.
Answer: 40 people
Step-by-step explanation:
There were 5 pies in the party and each person that came got an equal share of 1/8.
The number of people who were there is therefore:
= Number of pies / Share each person got
= 5 ÷ 1/8
= 5 * 8/1
= 40 people
Answer:
10.2
Step-by-step explanation:
Answer:
23.5 cm
Step-by-step explanation:
The model distance x is proportional to the scale:
x/(47 ft) = 1 cm/(2 ft)
Multiplying by 47 ft gives ...
x = (1 cm)(47/2) = 23.5 cm
The distance from half-court on the model is 23.5 cm.
Before we calculate we can use some common sence thinknig to narrow down the choices. We know that Robert is gonig DOWN the hill, so it doesnt make sence that he woudl have a positive rate of change (i.e. the number feet up the hill he is is decreasing, not increasing) So right away, A & B are clearly wrong.
If we look at the last two (C & D) we can see that if -460 were right after 10 minutes he would have walked down 4,600 feet. This is WAY more that the total height of the hill and so can't be correct.
So C must be correct.
We can check this with some simple math:
