Step-by-step explanation: For 28

1. A = L*W

2. A = 240

3. 240 = 12*W

4. (240/12) = W

5. 20ft = W

Step-by-step explanation: For 29

X +300 = -40

X = -40 - 300

X = -340

Help me on this please

lakkis [162]

Answer:

5 miles.

Step-by-step explanation:

The Pythagorean theorem $a^{2}+b^{2} =c^{2}$ will find any side length of a perpendicular triangle when two sides are known.

We substitute for a, the shortest side, a=3 and for b, the longer side, b=4 to find the slanted hypotenuse c.

$a^{2}+b^{2} =c^{2} \\3^{2}+4^{2} =c^{2} \\9+16=c^{2}\\25=c^{2}\\5=c$

The direct route is 5 miles.

Answer:

(12/1.35)^2 ~= 79.012346

(roughly equal to ~=)

Step-by-step explanation:

divide both sides by 1.35

12/1.35 = √x

square both sides to get rid of √

(12/1.35)^2 ~= 79.012346

10 oz of salmon is needed for 16 servings

20 oz of salmon is needed for 32 servings

50 oz of salmon needed for 80 servings

62.5 oz of salmon needed for 100 servings

<em><u>Solution:</u></em>

Given that,

One roll can be cut into 8 servings

The ingredients for one roll include sushi rice, seaweed sheets, cucumbers, cream cheese, and 5oz of smoked salmon

1 roll is 8 servings and it is made of 5 oz of smoked salmon

Which means that, 5 oz of smoked salmon is needed fo 8 servings

Write an expression for the amount of salmon needed to make s serving of sushi

$Amount\ of\ salmon = \frac{5}{8}s$

Where, s = serving

<h3><u>How much salmon is needed to make ?</u></h3><h3><u>16 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 16 = 5 \times 2 = 10$

Thus 10 oz of salmon is needed for 16 servings

<h3><u>32 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 32 = 5 \times 4 = 20\ oz$

Thus 20 oz of salmon is needed for 32 servings

<h3><u>80 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 80 = 5 \times 10 = 50\ oz$

Thus 50 oz of salmon needed for 80 servings

<h3><u>100 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 100 = 5 \times 12.5 = 62.5\ oz$

Thus 62.5 oz of salmon needed for 100 servings

She uses 18 square inches of paper for each card How many square feet of paper does she need to make 150 cards

gizmo_the_mogwai [7]

Answer:

225

Step-by-step explanation:

Well, we already know how many square inches each card is. 18. All we need to do is multiply that number by 150 because we need to make 150 cards. So:

18 x 150 = 2,700inches.

Now all we need to do is divide the number of inches by the amount each foot is. Each foot is 12 inches. So:

2,700 ÷ 12 = 225.

225 is your answer.

<u>Hope this helps and have a nice day!</u>
