Answer:

1. 24 quarts. 2. 85 seconds.

Step-by-step explanation:

1. We need to know how many 2/3 are in 4.

if 3/3 are in 1 cup, then 12/3 are in 4 cups.

there are 6 twos in 12, so there are 6*2/3 cups in 4 cups.

Each 2/3 needs 4 quarts of green, and we have six times that.

6*4 = 24, so we need 24 quarts of green paint.

2. The 12.75 miles would go in the "d" or distance part of the equation.

d = 0.15t

12.75 = 0.15t (divide both sides by 0.15)

12.75/0.15 = 0.15t/0.15

t = 85, so 85 seconds.

12.75 miles isn't the distance between the two cities, it's much farther, so this answer makes sense.

What is the area of the right triangle shown?

prisoha [69]

The 30:60:90 proportion is 1:sqrt 3: 2

So,

x = 10/2
x = 5

y = 10/sqrt 3

Finding the area:

1/2 * 5 * 10/sqrt 3
25/sqrt 3

Hope this helps!

This box can be packed with 48 units cubes. The edge length of each unit cube is 1 meter. What is the volume of the box?

Dafna1 [17]

48 m³

Step-by-step explanation:

A cube has equal length width and height

A cube in this case has length 1m meaning the width and height are also 1 m each in length.

The volume of the cube is (L * W * H) = 1 * 1 * 1 = 1 m³

If 48 of these can fit in the bigger box, then the bigger box has the volume of;

48 * 1 m³ = 48 m³

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = x

Opposite leg AC = 24

Adjacent leg CB = 35

Step 2: Solve for x

Substitute in variables [Tangent]: $\displaystyle tanx^\circ = \frac{24}{35}$
Inverse Trig [Tangent]: $\displaystyle x^\circ = tan^{-1}(\frac{24}{35})$
Evaluate: $\displaystyle x = 34.439^\circ$
Round: $\displaystyle x \approx 34^\circ$
