The mean is the average so 180/50 = 3.6 therefor the mean of each donation from each sponsor is £3.60

Answer:

Step-by-step explanation:

Given the 2 equations

4x + 8y = 21 → (1)

y = - $\frac{1}{2}$ x + 3 → (2)

Substitute y = - $\frac{1}{2}$ x + 3 into (1)

4x + 8(- $\frac{1}{2}$ x + 3 ) = 21 ← distribute parenthesis on left side

4x - 4x + 24 = 21 ( subtract 24 from both sides )

0 = - 3 ← not possible

This indicates the system has no solutions

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

$Ar=W . I$

If we know that the area measures $37.8 m^{2}$ and one side of the figure measures 4.2 m, we can say that:

$37.8m^{2}=4.2m. I$

We isolate the side we don't know:

$\frac{37.8m^{2}}{4.2m} = I\\9 m = I$

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

$P= I. 2 + W . 2$

$P= 9m. 2 + 4.2m. 2$

$P= 26.4 m$
