Answer: 333.33m²

Step-by-step explanation:

Since we are informed that 15 litres of paint covers an area of 250 m2, the the area that 1 liter of paint will cover will be:

= 250m²/15

= 16.666667m²

Therefore, the area that 20 litres of paint will cover will be:

= 16.666667m² × 20

= 333.33m²

Which fraction has the value that's equal to 3/4

mamaluj [8]

One of the fractions that’s equal to $\frac{3}{4}$ is $\frac{12}{16}$

Solution:

Given that , we have to find fractions which has the same value as that of the fraction $\frac{3}{4}$

Now, we know that, there are several fractions with values equal to $\frac{3}{4}$

To find them, just multiply the numerator and denominator by the same number.

$\begin{array}{l}{3 \times 2=6} \\\\ {4 \times 2=8}\end{array}$

Therefore, $\frac{6}{8}$ is equal to $\frac{3}{4}$

We can do the same with 4, to get $\frac{12}{16}$ , or any other number beyond that.

Hence, one of the fractions that’s equal to $\frac{3}{4}$ is $\frac{12}{16}$

How do I use the substitution method to find the point of intersection of

Goshia [24]

To substitute, solve for one variable and then plug it into the other equation you have. In this problem, y is already solved for on the top equation (y=x+2), so you just stuff it into the second equation.

y = x + 2
3y = 4x - 2

3(x + 2) = 4x - 2
3x + 6 = 4x - 2
-x = -8
x = 8
y = x + 2 = 8 + 2 = 10

solution:
x = 8
y = 10

hope this helps!! :)

Find the geometric mean of four and 10

lawyer [7]

The Geometric mean of 4 and 10 is 6.32

Explanation:

Given:

Two numbers are 4 and 10

Geometric mean, GM = ?

We know,

GM = $\sqrt[n]{a_1 X a_2}$

Where,

n = 2

Substituting the value we get"

$GM = \sqrt[2]{4 X 10} \\\\GM = \sqrt[2]{40} \\\\GM = 6.32$

Thus, the Geometric mean of 4 and 10 is 6.32
