One rectangle has a base of 12 inches and an altitude of 6 inches. The other has a base of 10 inches and an altitude of 5 inches

guajiro [1.7K]

Ratio of their bases = $$\frac{12}{10}$

Ratio of their altitudes = $$\frac{6}{5}$

<u>Step-by-step explanation:</u>

For first rectangle, it was given that

Base 1 = 12 inches

Altitude 1 = 6 inches

For the second rectangle, it was given that

Base 2 = 10 inches

Altitude 2 = 5 inches

Ratio of their bases is given by the ratio of the base of the first rectangle to the second one.

Ratio of their altitudes is given by the ratio of the altitude of the first rectangle to the altitude of the second rectangle.

Ratio of their bases = $$\frac{12}{10}$

Ratio of their altitudes = $$\frac{6}{5}$

The tire of his unicycle has a circumference of 2.8m , point,, and the tire revolves 1.51.51, point, 5 times per second. What is

I am Lyosha [343]

Answer:

Benjamin travels 7 meters in 100 seconds.

Step-by-step explanation:

We are given the following in the question:

Circumference of tire = 2.8 m

Revolution of time = 1.5 times per minute.

Total time = 100 seconds.

We have to calculate distance covered by Benjamin.

Total number of revolution of tires =

$=\text{Revolution rate}\times \text{Time}\\\\=1.5\text{ revolution per minute}\times \dfrac{100}{60}\text{ minutes}\\\\=2.5 \text{ revolutions}$

Total distance covered by Benjamin =

$=\text{Number of revolution of tires}\times \text{Circumference of tire}\\=2.5\times 2.8\\=7\text{ meters}$

Thus, Benjamin travels 7 meters in 100 seconds.
