Answer:
3375
Step-by-step explanation:
The surface area formula for a cube is:
A = 6 a^2
We know what the area is so plug it into the equation:
1350 = 6 a^2
225 = a^2
a = 15
Now plug a = 15 into the equation for volume of a cube:
V = a^3
V = 15^3
V = 3375
Answer:
28 pans of muffins per week
Step-by-step explanation:
To solve the above question, we know that:
1 day = 4 pans of muffins
7 days = x pans of muffins
Cross Multiply
1 day × x pans of muffins = 7 days × 4 pans of muffins
x = 28 pans of muffins
Since, 7 days = 1 week
Heather makes 28 pans of muffins per week
Answer:
<h2>$32</h2>
Step-by-step explanation:
Step one:
Given that membership is $9 and the cost per visit is $1
let the number of visits be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that x=23, we can solve for the totals cost as
by substituting we have
y=1*23+9
y=23+9
y=32
<u>The total cost for 23 visits is $32</u>
