<h3>Answer: True</h3>

Explanation:

A rectangle has all four angles that are 90 degrees. The side lengths may or may not all be the same length; however, we do know that the opposite sides are the same length.

A square is a special type of rectangle where all four sides are the same length and all angles are 90 degrees.

If a figure is a square, then it is automatically a rectangle, but not the other way around.

A museum has a wax sculpture of a historical village. The scale is 1.5:8. If the height of a hut in the sculpture is 5 feet, how

Oksi-84 [34.3K]

Let us say that x is the real height of the original hut, therefore we can establish the equation:

5 : x = 1.5 : 8

5 / x = 1.5 / 8

Solving for x:

x = 5 * 8 / 1.5

x = 40 / 1.5

If (5x-3y)²=0, then x/y=?

alexandr1967 [171]

Answer:

$\frac{3}{5}$

Step-by-step explanation:

Given

(5x - 3y)² = 0, then

5x - 3y = 0 ( add 3y to both sides )

5x = 3y (divide both sides by 5 )

x = $\frac{3}{5}$ y ( divide both sides by y )

$\frac{x}{y}$ = $\frac{3}{5}$

A car travels 45km in an hour. In each of the next two hours, it travels 78km. What is the average speed of the car.

romanna [79]

Answer:

The average speed of car is 67 kilometers per hour.

Step-by-step explanation:

Given that:

Distance travelled in one hour = 45 km

Distance travelled in next 2 hours = 78*2 = 156 km

Total distance = 45+156 = 201

Total time = 1+2 = 3 hours

Average speed of the car = $\frac{Total\ distance}{Total\ time}$

Average speed of the car = $\frac{201}{3}$

Average speed of the car = 67 km/hr

Hence,

The average speed of car is 67 kilometers per hour.
