Test of a new car results in 310 miles on 20 gallons of gas, how far could you drive on 50 gallons of gas? what is the cars gas mileage?

775 miles

Mileage = 15.5 miles per gallon of gas.

Step-by-step explanation:

Test of a new car results in 310 miles on 20 gallons of gas.

We have to calculate the number of miles that the car goes on 50 gallons of gas.

If the mileage of the car is constant, then we can use the unitary method to get the number of miles the car goes on 50 gallons of gas.

Therefore, the car will go miles with 50 gallons of gas.

Now, the mileage of the car will be miles per gallon of gas. (Answer)

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
