Steps:

- sqrt 315 / sqrt 5

315 / sqrt 5     =     3^2  *   7 sqrt 5

- sqrt 3^2  *  7 sqrt 5

Simplify:

sqrt 3^2 sqrt 5  *   7 :        3 sqrt 7^4 sqrt 5

=         -3 sqrt 7^4 sqrt 5

Answer   =======>      −11.868963

Which expressions are equivalent to 22c + 33d?
harkovskaia [24]

Answer:

A, C, and E

Step-by-step explanation:

For the first one, distribute -11 to each value. A negative times a negative is a positive, so -11×-2c is 22c. -11×-3d is 33d. So the first one is right. For the third one, distribute 1/3 to each value. 1/3 of 66c is 22c, and 1/3 of 99d is 33d, so the third one is correct as well. For the last one, distribute 11 again. 11×2c is 22c and 11×3d is 33d, so the last one is correct.

Jim's backyard is a rectangle that is 16 5/6 yards long and 10 2/5 yards wide. Jim buys sod in pieces that are 1 1/3 yards long
lora16 [44]

Answer:

93 pieces

Step-by-step explanation:

To cover his backyard with sod, he needs to cover the area of the backyard.

His backyard is a rectangle, and area of a rectangle is given as:

Where,

is the length, and

is the width

So, the area of Jim's backyard is square yards.

The area of each sods are solved using the area of the rectangle formula. So we have square yards as the area of each sod.

To find HOW MANY of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:

Since, fractional sods can't be bought, Jim has to buy 93 sods to cover his backyard.

Test the four possible vertices that you found in the objective function in part A. Use those values to determine which set of v
irga5000 [103]

The testing of the four vertices of the objective function gives;

C(5, 0, 55) = 430

C(5, 30, 25) = 400

C(15, 30, 15) = 420

C(45, 0, 15) = 510 (maximum)

<h3>How to test objective functions?</h3>

The objective function is seen as attached.

Now, it is noticed that just two of the vertices are listed. The other two vertices are intersections of x + y + z = 60 with x = 5 and the constraints on y.

We will assume that; 0 ≤ y ≤ 30

Thus, the missing vertices are;

(x, y, z) = (5, 0, 55)  and  (5, 30, 25)

The two given vertices are;

(x, y, z) = (15, 30, 15)  and  (45, 0, 15)

Therefore, the objective function values are;

C(5, 0, 55) = 9·5 +6·0 +7·55 = 45 +0 +385 = 430

C(5, 30, 25) = 9·5 +6·30 +7·25 = 45 +180 +175 = 400

C(15, 30, 15) = 9·15 +6·30 +7·15 = 135 +180 +105 = 420

C(45, 0, 15) = 9·45 +6·0 +7·15 = 405 +0 +105 = 510
