The total is 33 bikes. 27 out of the 33 bikes are red. Therefore, we have a number of parts to a whole, so we can create a fraction to calculate the percentage of red bikes.

27/33 = .818

.818 x 100 = 81.81%.

• To calculate a percentage, divide the numerator by the denominator and multiply by 100. Here’s a formula to remember: n/d•100, where n=numerator and d=denominator.

Therefore, 81.81% of the bikes are red.

I need help ASAP!! Please explain how to do solve the problem.

olga55 [171]

Answer:

Step-by-step explanation:

The co-ordinates of the smaller and larger triangles are 4,5 3,2 & 6,3 and 12,15 9,6 18,9

To find out dilation factor,

Co-ordinates of smaller triangles* dilation factor=co-ordinates of

larger triangles(or use (kx,ky) where k is the dilation factor and x and y are the co-ordinates)

(4,5) (3,2) (6,3)k=(12,15) (9,6) (18,9)

Equate and solve,

k=(12,15) (9,6) (18,9)/(4,5) (3,2) (6,3)[Informal]

k=3

A garden hose supplies 36 gallons of water in 3 minutes. Use a table of equivalent ratios to show the garden hoses water flow in

Eduardwww [97]

Answer:

1 minute:12 gallons

1 gallon:0.0833 minutes

Step-by-step explanation:

-Let x be the number of minutes and y be the number of gallons.

-Given that 36 gallons flow in 3 minutes, our table ratios can be calculated and represented as below:

$3 \ minutes=36\ gallons\\\\\therefore 1 \ minute=\frac{36}{3}=12 \ gallons\\\\2 \ minutes =12\ gallons \times 2= 24 \ gallons$

#We then calculate minutes per gallon as below:

$36\ gallons =3\ minutes\\\\\therefore 1 \ gallon=\frac{3}{36}\\\\=0.0833\ minutes$

Hence,the flow of gallons per minute and minutes per gallon are represented in table ratios as attached.

Eduardo counted ten seconds (y) between seeing lightning and hearing thunder, and he knew that the lightning was about 2 miles (

Fed [463]

Answer:

The equation for the variation is:

$\frac{Miles}{thunder\,\,time } =0.2\,\frac{mi}{s}$

Step-by-step explanation:

The relationship is given by the quotient between the two variables: (1) distance of the storm, and (2) the number of seconds to hear the thunder. That is:

$\frac{Miles}{thunder\,\,time } =\frac{2}{10} =0.2\,\frac{mi}{s}$
