So Length * Width = 480 in. sq.
L=1 1/5 or 1.2W
substitute the L for 1.2W
1.2W*W=480 in sq
divide both sides by 1.2
w*w= 400
W²=400
square root of both sides
Width = 20 inches
Length= (1.2width) or (20*1.2)
Length=24 inches

PLEASE HELP I WILL GIVE BRAINLIEST!!!!!!
Natasha2012 [34]

Answer:

3rd answer EF =  2√13

Step-by-step explanation:

Make a right triangle and use Pythagorean theorem a²+b² = c²

Go from point  F 6 units down till point (1,-3) .From that point go 4 units left till you hit point E.

Triangle has legs a and b that are 6 and 4 units long so 6² + 4² = EF²

36 + 16 =  52

EF² = 52 find √52

EF = √52

There is no √52 as a whole number so rewrite 52 as a product of number who was a √ and the other who doesn't have a √

52 = 4 * 13

EF = √4 * √13 = 2√13

Several friends bought flowers to make table centerpieces. write the ratios of purple flowers to white flowers for each friend.
Zina [86]

The ratio for Rowan = <u>4:1</u>.

The ratio for Marcia = <u>10:1</u>.

The ratio for Jillian = <u>5:1</u>.

The ratio for Lulua = <u>6:1</u>.

The smallest ratio among these for purple to white flowers is for Rowan, that is, <u>4:1</u>.

Ratios are fractions in the simplest form representing the relationship between two quantities.

The ratio of purple to white flowers for each friend can be shown as:-

Rowan:

The number of purple flowers = 8

The number of white flowers = 2

Thus, the fraction of purple to white flowers = 8/2 = 4/1.

Thus, the ratio for Rowan = 4:1.

Marcia:

The number of purple flowers = 10

The number of white flowers = 1

Thus, the fraction of purple to white flowers = 10/1.

Thus, the ratio for Marcia = 10:1.

Jillian:

The number of purple flowers = 10

The number of white flowers = 2

Thus, the fraction of purple to white flowers = 10/2 = 5/1.

Thus, the ratio for Jillian = 5:1.

Lulua:

The number of purple flowers = 18

The number of white flowers = 3

Thus, the fraction of purple to white flowers = 18/3 = 6/1.

Thus, the ratio for Lulua = 6:1.

The smallest ratio among these for purple to white flowers is for Rowan, that is, <u>4:1</u>.
