Answer:
The number of children (n) that can attend the birthday party can be expressed as;
n≤8
Step-by-step explanation:
Step 1
We can use the expression below to calculate the total cost of the party as shown;
C≥F+(V×n)
where;
C=total cost of Gina is willing to spend
F=fixed cost for the rent
V=cost per child
n=number of children at the party
In our case;
C=$100
F=$50
V=$6.25
n=n
replacing;
100≥50+(6.25×n)
6.25 n+50≤100
6.25 n≤100-50
6.25 n≤50
n≤50/6.25
n≤8
The number of children (n) that can attend the birthday party can be expressed as;
n≤8
Answer:
#3
Step-by-step explanation:
The height of building is 35 feet
<em><u>Solution:</u></em>
Given that,
Sam is 6 feet tall and his shadow is 3.6 feet tall
The shadow of building is 21 feet long
<em><u>To find: height of building</u></em>
We can solve this by setting up a ratio comparing the height of the building to the height of the Sam and shadow of the building to the shadow of the Sam
Let us consider,
= height of building
= height of Sam
= shadow of building
= shadow of Sam
Therefore,
Substitute the values,
Thus height of building is 35 feet
