Answer:
$24.875
Step-by-step explanation:
If we use an equation to solve the total amount, like y=9.95x where x is the gallons purchased. We then multiply 9.95 by 2.5 to get 24.875
<span>y - k = a(x - h)²
</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²
</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.
Vertex (5,8).
Answer:
35 [$]
Step-by-step explanation:
1) if Peter's sum is p and Jacky's is j, then the ratio 5:2 in the condition can be written j/p=5/2;
2) the phrase 'after Jacky gave 15 dolls to Peter, they have an equal number of dolls' can be written as j-15=p;
3) using the two above it is possible to make up the system of two equations:

4) finally, the have together 10+25=35 doll-s.
3/5 doesn't belong with the other three
Answer:
Surface area = 85.84 ft²
Step-by-step explanation:
Considering the fact that large rectangle area = 6 x 12 = 72 ft²
Also, the two triangles area => 2(0.5 * base * height) = 2(4 x 3.46 x 0.5) = 13.84 ft²
Hence, the total surface area is
72 + 13.84 = 85.84 ft²
Therefore, the surface area of the fabric is 85.84ft²
