Answer:

A) y = 4x - 1

Step-by-step explanation:

y = mx + b

The volume of a Rubik’s cube is 512/216 cubic inches. Find the length of a side of the cube.
Sergeeva-Olga [200]

Answer:

4/3 inches, or 1.33333 inches

Step-by-step explanation:

In terms of the volume of a cube, its side length is the cube root of it. Therefore, for a cube with a volume of 512/216 cubic inches, its side length is equal to ∛(512/216) = ∛(512)/∛(216) = 8/6 = 4/3 inches*

* we know that 8/6 = 4/3 because we can multiply both the numerator and denominator by 1/2 to get this result. If we multiply/divide the numerator or denominator by the same values, the fraction is still the same

What is the distance between (4, 6) and (5, 0)
tresset_1 [31]

Answer:

6 units

Step-by-step explanation:

Given data

x1=4

y1=6

x2=5

y2=0

substitute in the formula for the distance between two points

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((5-4)²+(0-6)²)

d=√((1)²+(6)²)

d=√36)

d=6

Hence the distance is 6 units

Catie is trying to determine the height that a ladder reaches as it leans against a wall. She walks under the ladder and touches
brilliants [131]
18.56 feet
Catie creates a similar triangle with the ladder so we can create a proportion to solve for the height.  
\frac{baseto feet}{base to wall} = \frac{catie height}{wall height}
Convert all values to feet . 16in = 1.33 ft . 5ft 6 in = 5.5 ft 
Insert values into proportions
\frac{1.33}{4.5} = \frac{5.5}{x}
Cross multiply to get
24.75=1.33x
divide both sides by 1.33
x=18.56ft
