A school system is testing a new math teaching strategy for geometry. Ten classes were randomly selected to pilot the new strate

gy, and 10 classes were randomly chosen to continue using the current strategy. At the end of the school year, more than 50% of the data overlapped. Consequently, the school system could not make a determination about which teaching strategy produced higher test scores. What can the school system do to make the decision more definitive?

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

Triangle XYZ is rotated 90° clockwise about the origin. On a coordinate plane, triangle X Y Z has points (negative 3, 1), (4, 4)
ozzi

Answer:

(1,3), or option 1

Step-by-step explanation:

The formula for a 90 degree clockwise rotation is (x,y)------>(y,-x). In this case it started out as (-3, 1). Using the formula you get (1,-3(-1)), which is equal to (1,3). Hence option 1 is correct

the base of a ten foot ladder stands six feet from a house. How many feet up the house does the ladder reach
Ludmilka [50]
In this problem you will need to use the Pythagorean theorem (c^2=a^2+b^2).
The a and b represents the two edges, while c is the diagonal side and it is called the hypotenuse. Since you already know what the hypotenuse is and what one of the sides already are you just have to use the problem: c^2-a^2=b^2. Then if you plug the data you already have into the problem you will get 10^2-6^2=b^2. That then equals 100-36=b^2. Then you subtract and get b^2=64. Then you square root both sides and you get the answer b=8.
