Each quilt takes 3 yards of material so it would be 36

If it takes 21 yards to make 7 quilts, then we can divide the reactants by the product, so we just do:

21 / 7 = 3

Since it takes 3 yards to make 1 quilt, it will take 21 yards to make 7 quilts. Now we've figured out how many yards it takes per single quilt, but that'ts not what the question asks, so we go back to the question and see that we need enough material to make 12 quilts. From here, the solution is as easy to find as saying

3 * 12 = 36
36 yards.

Now we know how many yards it takes to make 12 quilts and the problem is solved.

In parallelogram HJKL if m∡HJK=110∘ find m∡JKL.
pav-90 [236]

Answer:

∠ JKL = 70°

Step-by-step explanation:

Consecutive angles in a parallelogram are supplementary , then

∠ JKL + ∠ HJK = 180°

∠ JKL + 110° = 180° ( subtract 110° from both sides )

∠ JKL = 70°

The volume of a right circular cone is 2,279.64 in cubed. If the height of the cone is 18 in, what is the diameter of the cone?
Aleksandr [31]

ANSWER

A. 22 in

EXPLANATION

The volume of a cone is calculated using the formula:

Volume =  \frac{1}{3}  \times \pi {r}^{2} h

It was given that: the volume is 2,279.64 in³

The height of the cylinder is also given as: h=18 in.

We substitute, the given values into the formula to get:

2279.64=  \frac{1}{3}  \times (3.14) \times {r}^{2}  \times 18

2279.64= 18.84 {r}^{2}

{r}^{2}  =  \frac{2279.64}{18.84}

{r}^{2}  = 121

We take positive square root to get;

r =  \sqrt{121}

r = 11in

Therefore the diameter is 2(11) which is equal to 22 inches.

Answer:

  • 92.5

Step-by-step explanation:

<u>The data given:</u>

  • 93, 81, 94, 71, 89, 92, 94, 99

<u>Put the data in the ascending order:</u>

  • 71, 81, 89, 92, 93, 94, 94, 99

<u>Since the data size is even, the median is the average of middle two:</u>

  • median = (92 + 93)/2 = 92.5
