Answer:

17 feet

Step-by-step explanation:

A bag of lawn fertilizer covers 289 square feet

Dimensions of the largest square plot of lawn that the bag of fertilizer will cover.

Area of a square lawn = length^2

Area of the square lawn = 289 square feet

Area of a square lawn = length^2

289 = length^2

Find the square root of both sides

√289 = √length^2

17 = length

Length = 17 feet

Dimensions of the largest square plot of lawn that the bag of fertilizer will cover = 17 feet by 17 feet

An airplane can cruise at 570 mph. How far can it fly in 4/3 hours?

cestrela7 [59]

Answer:

The plane can fly 760 miles in 4/3 hours.

Step-by-step explanation:

Given that:

An airplane can cruise at 570 miles per hour.

We have to find the distance travelled by train in 4/3 hours.

Distance = Speed * Time

Distance = $570*\frac{4}{3}$

Distance = $\frac{2280}{3}$

Distance = 760 miles

Hence,

The plane can fly 760 miles in 4/3 hours.

Hypotenuse of triangle with sides of 36 and 39

worty [1.4K]

Answer: The hypotenuse is 53 (approximately)

Step-by-step explanation: In this question we shall apply the Pythagoras theorem which states that;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse and AB and BC are the two other sides. Having been given that the two other sides are 36 and 39 units respectively, the hypotenuse is now,

AC^2 = 36^2 + 39^2

AC^2 = 1296 + 1521

AC^2 = 2817

Add the square root sign to both sides of the equation

AC = 53.0754

Therefore the hypotenuse is approximately 53 units.
