natali 33 [55]3 years ago
3 0

Answer: 1/3 = 33.3% or 33 ⅓%

1/9 = 11.1%

2/9 = 22.2%

8/9 = 88.9%

Step-by-step explanation:

Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.

All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.

Ashton bought 5 cans of olive oil. Each can had a radius of 3.2 inches and was 15 inches tall. Find the total cubic inches of ol
amid [387]

Step-by-step explanation:

A can is a cylinder.

Volume of a can = Volume of Cylinder

= \pi {r}^{2} h

Given Radius = 3.2 inches and height = 15 inches,

Volume of one olive oil can =

\pi( {3.2}^{2} )(15) \\  = 153.6\pi {in}^{3}

Volume of 5 olive oil cans = 5 x volume of one olive can

= 5 \times 153.6\pi \\  = 768\pi {in}^{3}

I will just leave the answer in terms of pi as I'm not sure if you need to round off your answers.

Write each equation in slope - intercept form, then find the slope and y-intercept:
Rasek [7]
1/2x + 3/4y = 4 ....multiply everything by 4
2x + 3y = 16
3y = -2x + 16
y = -2/3x + 16/3

In y = mx + b form, the slope will be in the m position and the y int will be in the b position

y = mx + b
y = -2/3x + 16/3

so ur slope is -2/3 and ur y int is (0,16/3)

jekas [21]

Answer:

Scale factor = 3

Step-by-step explanation:

Scale factor used for the dilation = the ratio of the corresponding side length of the new figure to the side length of the original figure

Scale factor = B'C'/BC

B'C' = 9 units

BC = 3 units

Scale factor = 9/3 = 3
