a basket of laundry is being separated.  Divide 48 pieces of clothing into 2 groups so that the ratio is 1:3

Answers

The answer to this question would be 12 cloth: 36 cloth

In this question, you are asked to divide the clothing into 1:3 ratio. That mean, you need to divide the clothing into 4 parts (1+3), then put 1 part in one basket and 3 parts in other baskets. The calculation would be:

Basket 1= 48 cloth * 1/(1+3)= 12 cloth
Basket 2= 48 cloth * 3/(1+3)= 36 cloth

Answer:

12

Step-by-step explanation:

1+3=4

so 48/4=12

Find the area of a 45°-45°-90° triangle with a hypotenuse of 24. a. 144 square units c. 99 square units b. 125 square units d. 100 square units

Answers

area=1/2 times base times height


remember that 45-45-90 triangle has sides of x,x and x√2
(legs are measure x and hypotonuse=x√2)

the legs are equal and are also the base and height
find the legs (x=leg)


hypotonuse=24
24=x√2
divide both sides by √2
24/(√2)=leg=base=height

volume=1/2 times base times heigth
V=1/2 times (24/√2) times (24/√2)

What is the equation in point−slope form of the line passing through (2, 2) and (4, 8)?(y − 2) = 3(x − 2)
(y + 2) = 3(x + 2)
(y − 8) = −3(x − 4)
(y + 8) = −3(x + 4)

Answers

Hello,

1) y-8=(8-2)/(4-2)(x-2) ==>y-8=3(x-2) (not in answer!)
