hich correctly explains how to estimate 33 percent of 87?
Round 33 percent to 20 percent and 87 to 80. Think of 20 percent as 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 30 percent of 80 is 8 + 8, which is 16.
Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 35 percent and 87 to 90. Think of 35 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 35 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 40 percent and 87 to 80. Think of 40 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 40 percent of 90 is 8 + 8 + 8, which is 24.

Fill in the inequalities below to specify the graph's range shown.

Range: __ is not greater than or equal to y, which is below 5.

The domain and range is the graph's domain is its set of potential input values, and its range is its set of potential output values.

Following is the finished inequality reflecting the set of the domain and range;

First,

Domain: -4 is below x, which is below or equal to 4.

Second,

Range: -2 is below y, which is below or equal to 5

The attached graph shows that the point (-4, 5) has an open circle, which denotes that the point has no value.

The closed circle at the other end of the graph, at the coordinates (4, -2), denotes that the graph has a value at that location (4, -2)

First,

The domain of a graph is the set of potential inputs (x-values) for the graph, expressed as inequality is -4 < x ≤ 4

Therefore;

To complete the inequality for the domain, gives;

Domain: -4 is less than x which is less than or equal to 4

Second,

The range of a graph are the possible output (y-values) of the graph, in inequality notation, the domain of the attached graph is -2 ≤ y < 5

the domain supplies the necessary inequality to be complete;

Range: -2 is less than or equal to y which is less than 5.

Answer:

0.78 cubic inches/sec

Step-by-step explanation:

you take 3.9 cubic feet and multiply it by 12 to convert it into inches and you get 46.8 cubic inches. then you divide by 60 to convert minutes to second and you get 0.78. hope that helps

Answer:

1123.2 cubic inch per second

Step-by-step explanation:

3.9 feet^3 = per minute

? = second

39 = 60 sec

? = 1 sec

39/60 =0.65 feet cubic

1 cubic foot = 1728 cubic inch

0.65 feet cubic = ?

0.65 * 1728

= 1123.2 cubic inch

Look at the line carefully. You can see that the line crosses the point (0,2). See it? The value of 2 in the point (0,2) is the y-intercept.

The given equations are all in the form

y = mx + b, where b is the y-intercept.

So, based on this data, we conclude that the line represents the equation y = (1/3)x + 2.

Step-by-step explanation:

Step 1: Define

m/2

m = -8

Step 2: Evaluate

Answer: -4

Step-by-step explanation: It's important to understand that m/2 means

the same thing as m ÷ 2.

In this case, we are given that m = -8.

So we have -8 ÷ 2 which is -4.

Remember that when you divide a negative number

by a positive number then the quotient is negative.

The graph that has the slope that best represents the unit rate of 4 miles per hour is: graph B.

For any proportional relationship, we can find the slope of the graph by using any point on the line of the graph. The slope of the graph is also the unit rate, Therefore, picking a point on the line, (x, y), we have:

Slope (m) = y/x.

Number of miles Tyrell walks (y) = 12 miles

Time spent working (x) = 3 hours

The unit rate or slope = y/x = 12/3

Slope/unit rate (m) = 4 miles per hour.

From the graphs given, only graph B has the same unit rate/slope as 4, when we use the point, (5, 20).

Slope of graph B = 20/5 = 4.

Therefore, the graph that has the slope that best represents the unit rate of 4 miles per hour is: graph B.

Answer:

-.82

Step-by-step explanation:

To find the average rate of change over an interval, you use rise over run with the first point and the last point (in this case, the first point is (50, 35.8) and the last point is (60, 27.6)). This will give you an average rate of change of -.82.

In the context of this problem, -.82 is how much your expected remaining life span decreases each year.

Answer:

The correct option is;

f(x) = 64(three-fourths)Superscript x minus 1

Step-by-step explanation:

The first peak height that the bouncing toy reaches = 64 inches

The second peak height that the bouncing toy reaches = 48 inches

The third peak height that the bouncing toy reaches = 36 inches

Therefore, given that the sequence has a common ratio, r = 48/64 = 36/48 = 3/4

The first term of the sequence, a = The first peak height reached = 64

The xth term of the geometric sequence with general form, xth term = ar⁽ˣ⁻¹⁾

The xth term of the geometric sequence, f(x), is therefore, given as follows;

Answer:

im trying to get 50 points

Step-by-step explanation:

Answer:

The pipe lengths are 50 inches and 100 inches.

Step-by-step explanation:

If we refer to the length of the shorter piece as x, then we can say the length of the larger piece is 2x.  We are also told that the pipe length is 150 inches, so we can say:

x + 2x = 150

3x = 150

x = 150/3

x = 50

So the pipe lengths are 50 and 100 inches respectively.
