You can solve this by using the system of equations.
Jan - 4.95 = 2H + 3C
Wayne - 5.45 = 3H + 2C

Use elimination.
-3(2H + 3C = 4.95)
2(3H + 2C = 5.45)

Solve. And you'll get:
-6H + (-9C) = -14.85
6H + 4C = 10.9

Cross out -6H and 6H because they cancel out. And you're left with:
-9C = -14.85
4C = 10.9

Add -9C with 4C, and -14.85 with 10.9.
-5C = -3.95

Divide each side with -5.
C = $0.79

Now to figure out what H is, just substitute the C in one of the equations with 0.79.
5.45 = 3H + 2(0.79)
5.45 = 3H + 1.58
-1.58            -1.58
3.87 = 3H
3.87/3 = 3/3(H)
1.29 = H

Kyle has a storage box that is 2 ft. long, 3 ft. high, and has a volume of 12 ft.3
Eva8 [605]

Alright, let get started.

Kyle has a storage box having dimensions 2 ft long, 3 ft high and volume 12 cubic feet.

The formula for volume is = length * width * height

Suppose the width is w so,

12 = 2 * 3 * w

12 = 6w

Dividing by 6 in both sides

w = 2 feet

Myla has a storage box that is 4 ft high and 2 feet long and volume 16 cubic feet.

Suppose the width is w hence

16 = 4 * 2 * w

16 = 8 w

Dividing 8 in both sides

w = 2 feet

Hence the width of Kyle and Myla's boxes, both are 2 feet. : Answer

Hope it will help :)

Explain how you find it
aliina [53]

Answer:

x = 39

Step-by-step explanation:

there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two

so, (36 + 42)/2 = x

36 + 42 = 78

78/2 = 39

Suppose Wesley is a marine biologist who is interested in the relationship between the age and the size of male Dungeness crabs.
Eva8 [605]

Answer:

20.24 cm

Step-by-step explanation:

Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.

The formula obtained for the estimated size Y was

Y = 9.1411 + 0.4775X  

where X is the age in months

Replacing X with 23.2417, we get

Y = 9.1411 + 0.4775*23.2417 = 20.24 cm
