Answer: He must save for 11 or more weeks.
Step-by-step explanation:
Using the inequality, we will solve for x to determine the number.
130 + 20x > 350 Subtract 130 from both sides
-130 -130
20x > 220
x> 11
Since x is greater than 11, it means that if he saves for 11 weeks, then he will save the exact amount of $350, but since he wants to save more, he must save for 11 or more weeks.
The equation would be y = 4x + 2 so just look with a graph that has a y-intercept of two, as well as moves up four and up 1 each time.
x / y
0 / 2
1 / 6
2/ 10
3 / 14
4 / 18
5 / 22
6 / 26
7 / 30
Answer:
549.8 inches³
Step-by-step explanation:
Volume of Cylinder = height × base, where base =
r².
The radius (r) is given, 5 inches, and so is the height, 7 inches.
We simply substitute these values into the equation.
V(volume) = 7 ×
× 5²
= 175
= 549.77871437821...
when we round that to the nearest tenth,
≈ 549. 8
Answer:
-300
Step-by-step explanation:
