Answer:
2.25
Step-by-step explanation:
Answer: $5.64
<u>Step-by-step explanation:</u>
Let x represent 1 box of batteries
Let y represent 1 case of batteries
Given: 14x = 3y
Given: 158 = 14x + 3y
Use substitution: 158 = 14x + 14x
Simplify: 158 = 28x
Divide by 28: 5.64 = x
Answer:
#4 y=-0.5(x-4)^2+1
Step-by-step explanation:
Answer:
A: 1/2 divided by 1 1/2 is 3. 1/2 divided by 1 is 2. 1/2 divided by 2 1/2 5. Multiply those numbers and you get 15 which is how many can fit. B: Idk how to answer part B but you can have part A.
Step-by-step explanation:
Length: 1 1/2. Width: 1. Height: 2 1/2. Volume: how much of ? can fit in a ?. To get the volume you multiply 1 1/2 x 2 1/2 x 1. Make the mixed numbers into improper fractions: 3/2, 5/2, 2/2. Now multiply the numerators: 5 x 3 = 15x 2 = 30. Now in order to finish it you put 2 as the denominator. : 30/2 which as a whole number is 15. 15 cubes can fit.
Answer:
(x + 4)² + (y - 7)² = 20²
Step-by-step explanation:
Graphing form
(x - h)² + (y - k)² = r²
(h, k) is the center = (-4, 7)
r is the radius = 20
-----------------------------------
Plug in the givens
(x + 4)² + (y - 7)² = 20²
