The answer is 14 you simplify the fraction 75/100 to 3/4 and multiply by 56 4 divides 56 into 14 multiply this by 3 and subtract from 56, 56-42=14 books

TIMED!!!
guajiro [1.7K]

Answer: Last option.

Step-by-step explanation:

The total amount of concrete in the ramp (V_t) will be the sum of the volume of the  rectangular prism (V_{rp}) and the volume of the triangular prism (V_{tp})

V_t=V_{rp}+V_{tp}

The formulas are:

V_{rp}=lwh

Where "l" is the lenght, "w" is the width and "h" is the height.

 V_{tp}=\frac{bhl}{2}

Where "l" is the lenght, "b" is the base and "h" is the height.

Substituting, we get:

V_t=V_{rp}+V_{tp}\\\\V_t=lwh+\frac{bhl}{2}\\\\V_t=(18in)(6in)(6in)+\frac{(8in)(6in)(18in)}{2}\\\\V_t=1,080in^3

The correct answer is A) y - 4 = -2/5(x + 1)

We know this because of the basic form of point slope form, which is shown below.

y - y1 = m(x - x1)

In which the point (x1, y1) is on the graph and m is the slope. When counting the slope, we can see that it is -2/5 based on the fact that for every two spaces the graph travels down, it moves to the right five. This eliminates options C and D and gives us this form to work with.

y - y1 = -2/5(x - x1)

Now we have the point (-1, 4), so we can plug this in to match it with a formula.

y - 4 = -2/5(x - -1)

y - 4 = -2/5(x + 1)

Solve each compound inequality and graph the solution. 2x 5 3 or 4x + 7 &lt; -25 &gt;​
Over [174]

The solution of the given compound inequality, 2x − 5 > 3 or 4x + 7 < −25, is <u>x < -8 or x > 4</u>. The graph of the inequality is attached.

In the question, we are asked to solve each compound inequality and graph the solution: 2x − 5 > 3 or 4x + 7 < −25.

We first solve each inequality separately as follows:-

1. 2x - 5 > 3,

or, 2x > 3 + 5,

or, 2x > 8,

or, x > 8/2,

or, x > 4.

2. 4x + 7 < - 25,

or, 4x < - 25 - 7,

or, 4x < - 32,

or, x < -32/4,

or, x < - 8.

Thus, the solution of the given compound inequality is x < -8 or x > 4.

Thus, the solution of the given compound inequality, 2x − 5 > 3 or 4x + 7 < −25, is <u>x < -8 or x > 4</u>. The graph of the inequality is attached.
