Answer:
4w + 3c = $27
5w + c = $25.50
Step-by-step explanation:
Let us assume the w represent the cost of the sandwich
And, the c represent the cost of the bowl in a soup
Now the equations are
4w + 3c = $27
5w + c = $25.50
These two should be the equations that represent the situation

The area of the triangle is 90 m²
Explanation:
Given that the base of the triangle is 15 m
The altitude of the triangle is 12 m
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
where b is the base and h is the altitude
Thus, we have,
and 
Substituting the values in the above formula, we get,
Multiplying the terms, we get,
Dividing, we get,
Therefore, the area of the triangle is 90 m²
First find the radius of the sphere
V = 4/3 * pi * r^3
Givens
pi but we don't need it's value. We need only know it is on both sides of the equal sign.
V = 972 pi
Formula
V = 4/3 pi r^3
Sub and Solve
972 pi = 4/3 pi r^3 Divide both sides by pi. The 2 pis cancel each other out.
972 = 4/3 R^3 Multiply both sides by 3/4
3/4 * 972= 4/3 * 3/4 * r^3
3/4 * 972 = r^3
729 = r^3
cuberoot(729) = r
Box
r = 9 This is not the answer
d = 2*r
d = 2*9
d = 18
s = d (which is the side of the box
s = 18
V box = 18^3
Vbox = 5832 in^3
Pretty big isn't it?
Answer:1.04%
Step-by-step explanation:
12.5/12 = 1.04166667
when we round this to the nearest hundredth its 1.04%
