Complete the sentence to explain how to use mental math to express 12/25 as a percent

Mathematics
1 answer:
Vlada [557]2 years ago

Answer: It's 48%. See below.

Step-by-step explanation:

By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.

One way to make \frac{12}{25} a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.

\frac{12}{25}  =  \frac{48}{100} = 48 %

This is very simple, and mental math is definitely possible. Hope this help.

Solve each system by substitution<br><br> 2x - 3y = -1<br> X + 4y = -6
lord [1]

Answer:

(- 2, - 1 )

Step-by-step explanation:

Given the 2 equations

2x - 3y = - 1 → (1)

x + 4y = - 6 → (2)

Rearrange (2) expressing x in terms of y by subtracting 4y from both sides

x = - 6 - 4y → (3)

Substitute x = - 6 - 4y into (1)

2(- 6 - 4y) - 3y = - 1 ← distribute and simplify left side

- 12 - 8y - 3y = - 1

- 12 - 11y = - 1 ( add 12 to both sides )

- 11y = 11 ( divide both sides by - 11 )

y = - 1

Substitute y = - 1 into (3) for corresponding value of x

x = - 6 - 4(- 1) = - 6 + 4 = - 2

Solution is (- 2, - 1 )

A satelite is 5,400 miles from the horizon of earth. Earths radius is about 4000 miles. Find the approximate distance the sateli
kakasveta [241]

Answer:

The distance of Satelite from the earth's surface = 2720.12 miles

Step-by-step explanation:

Below is the calculation for distance:

Use Pythagorean theorem

Distance, d² = 5400² + 4000²

d² = 45160000

d = 6720.12

Subtract the radius to find the distance from earth's surface.

Distance = 6720.12 - 4000 = 2720.12

The distance of Satelite from the earth's surface = 2720.12 miles
