Kierston needs to paint a wall of the youth center. She knows that 1 can of paint covers an area of 2.2 square meters. Kierston

Step2247 [10]

Answer:

See Explanation

Step-by-step explanation:

Given

$1\ can = 2.2m^2$

Required

Determine the number of cans for the wall

The dimension of the wall is not given. So, I will use the following assumed values:

$Length=20m$

$Width = 44m$

First, calculate the area of the wall

$Area = Length * Width$

$Area = 20m * 44m$

$Area = 880m^2$

If $1\ can = 2.2m^2$

Then $x = 880m^2$

Cross Multiply:

$x * 2.2m^2 = 1 * 880m^2$

$x * 2.2m^2 = 880m^2$

$x * 2.2 = 880$

Make x the subject

$x = \frac{880}{2.2}$

$x = 400$

400 cans using the assume dimensions.

So, all you need to to is, get the original values and follow the same steps

15 Points and ill mark brainliest!

Neat
of turf, 83.33333% of the 1050 were minor
so about 875 minor injuries in turf
and 10.857% of 1050 were substantial meaning about 114 substantial
leaving 63 severe field turf

meaning 938 minor in gras (totalminior-minorturf=grassminor)
so now we know that grassmionr=938 that that is 1
and hen that is 77.972 gras is mionr so 938=77.972%
1203 total gras
then 4.26 of gras is severe or about 51
and leaving about 217 substantial gras injuries
total them yourself
I have to go sorry bye hope this helped
