aliina [53]

Answer:

12 inches

Step-by-step explanation:

The storage bin is in the shape of a rectangular prism.

Its volume is 5400 cubic inches and its base area is 450 square inches.

The volume of a rectangular prism is given as:

V = L * W * H

where L = length

W = width

H = height

The product of the length and width gives the base area of the rectangular prism:

A = L * W

This implies that:

V = A * H

=> 5400 = 450 * H

H = 5400 / 450

H = 12 inches

The height of the bin is 12 inches.

4/7 + 1/8 = what does this equal

Fudgin [204]

Answer:

39/56

Step-by-step explanation:

When you add fractions, both of the base numbers (denominators) have to be the same number in order to add the top numbers (numerators).

The easiest way to do this is to multiply each denominator by the other number. For example, 8 * 7 and 7 * 8. So you will have 56 and 56. You also need to multiple the numerator by that number. So, 1 * 7 and 4 * 8. So you will have 7 and 32. This will show as 7/56 + 32/56. Finally, add the numerators - > 39/56

Solve the simultaneous linear equation 2x+5y=11, 7x+4y=2

Andrews [41]

Answer:

x = - $\frac{34}{27}$ and y = $\frac{73}{27}$

Step-by-step explanation:

2x + 5y = 11

7x + 4y = 2

Let's try elimination here since we have a system of equations:

-7(2x + 5y = 11) = -14x - 35y = -77

and

2(7x + 4y = 2) = 14x + 8y = 4

The x's cancel out now so let's combine the two equations:

-35 + 8 = -27

-77 + 4 = -73

-27y = -73

y = $\frac{73}{27}$

Now that we have y's value, let's plug that value in for y in the other equation. You may choose whichever equation you want to solve for x but it is recommended to use the easiest one. (Since this value is complicated, it won't really matter.)

2x + 5( $\frac{73}{27}$ ) = 11

2x + $\frac{365}{27}$ = 11

2x = - $\frac{68}{27}$

x = - $\frac{34}{27}$

To check and make sure you have the correct values, plug both values into the orginal equation and make sure the equation is true.
