Atrucking company makes 50 deliveries in 5 days how long will it take for them to deliver 400

This is the application of ratio and proportion. You have to formulate the proportion for this problem:

50 deliveries : 5 days = 400 deliveries : x days

The inner numbers when multiplies should equal the product of the outer numbers.

400 (5) = 50x

50x = 2,000

x = 40

Therefore, it would take 40 days for the trucking company to deliver 400 deliveries.

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'.
