The <em><u>correct answer</u></em> is:

409

Explanation:

Let x be the number of students who listed instagram as their favorite.  "32 fewer than two times" x would be

2x-32

We know that this is the number who preferred the other site, which is 786:

2x-32 = 786

Add 32 to each side:

2x-32+32 = 786+32

2x = 818

Divide both sides by 2:

2x/2 = 818/2

x = 409

Which expression gives the distance between the points (4, 6) and (7, -3)?
Ugo [173]
The distance formula is
\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.  In the ordered pair (4, 6), 4 is the <em /><em>x</em>-coordinate and 6 is the <em /><em>y</em>-coordinate.  In the ordered pair (7, -3), 7 is the <em>x</em>-coordinate and -3 is the <em>y</em>-coordinate.  Substituting those values in gives us
\sqrt{(4-7)^2+(6--3)^2}.  Since subtracting a negative is the same as adding a positive, we now have

A contractor needs to buy grass seed to cover a lawn. The dimension of the llama song below. One bag of grass seed cover isn’t i
DedPeter [7]

The minimum number of bags of seed the contractor needs to buy the to cover the entire lawn is 4

<h3>How to determine the number of bags</h3>

Start by calculating the area of the entire field using:

Area = Length * Width --- area of square

So, we have:

Area = (18 + 54 + 18)* 28

Area = 2520

Next calculate the area of the porch using:

Area = 0.5 * (L1 + L2) * H -- area of trapezium

So, we have:

Area = 0.5 * (54+ (54 + 18 + 18 - 14 - 14)) * 10

Area = 580

The difference between the areas of the entire field and porch is the area of the lawn.

So, we have:

Lawn= 2520 - 580

Lawn= 1940

The above means that, the area of the lawn is 1940 square yards

If one bag of grass covers 600 square yards, then the number of bags that can cover 1940 square yards is:

n =\frac{1940}{600}

n =3.23

Round to the next highest integer

n =4

Hence, the minimum number of bags of seed is 4 bags
