Answer: 10 inches.

Step-by-step explanation:

v=l*w*h

Let’s plug in your numbers:

4,331.25=22.5*19.25*h

Let’s simplify it.

4,331.25=433.125*h

Then divide both sides by 433.125 (.125=1/8 by the way).

10=h

The height is 10 inches.

Answer:

81.25

Step-by-step explanation:

Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.

Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.

Finally, add those two distances together so that you know the total distance:

49.75+31.5 = 81.25

Error interval for x is 4.65 ≤ x < 4.75.

Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.

The error is rounding the number is half of the unit of measure.

The number was rounded to the nearest 0.1 unit. so the error is half of 0.1 which is [tex]\frac{1}{2}[/tex] × [tex]0.1[/tex] = 0.05

∵ 4.7 + 0.05 = 4.75

and 4.7 - 0.05 = 4.65

Error interval for x is 4.65 ≤ x < 4.75.

The volume of sphere  = 268.08

Step-by-step explanation:

Below is the calculation for the volume of melon (sphere).

Given the diameter of the sphere is = 8 inches

Now find the radius by dividing the diameter by 2 = 8/2 = 4 inches

Now use the below formula to find the volume.

The volume of sphere  = [tex]\frac{4}{3} \times \pi \times r^{3}[/tex]

Answer:x=1,-9

Step-by-step explanation:

Answer:

it is arithmetic and the difference is 6

Step-by-step explanation:

Let the larger number be x and smaller number be y.

→ Sum of two numbers = 90

→ x + y = 90_(1)

Also,

→ Larger number = 14 + 3(Smaller number)

→ x = 14 + 3y_(2)

Substitute the value of x from equation (2) to (1) :

→ x + y = 90

→ 14 + 3y + y = 90

→ 14 + 4y = 90

→ 4y = 90 - 14

→ 4y = 76

→ y = 76 ÷ 4

→ y = 19

And, from the equation (2) ;

→ x = 14 + 3y

→ x = 14 + 3(19)

→ x = 14 + 57

→ x = 71

Therefore, larger number is 71 and smaller number is 19.

Answer:

3

Step-by-step explanation:

y = mx + b

m = slope

In this equation,

m = 3

Thus, the slope, or m, is 3.

General equation for slope-intercept form

y=mx+C

where m is slope

Comparing the given eqn y=3x

m= 3

Therefore, slope = 3

Answer and Step-by-step explanation:

In a polygon, when a shape is similar but dilated, the angles are still congruent.

Also, turn the pentagon QRSTP counterclockwise 90 degrees so it is upright and looks like pentagon ABCDE (making it easier to read).

A. The measure of angle P is 124 degrees, as it matches up with angle E.

B. To find the length of side r, we need to find the scale factor. We do this by looking at the given side on pentagon QRSTP (side RS) and match it with its similar side of pentagon ABCDE (side BC)

To find the scale factor, you divide the side of the bigger shape by the side of the smaller shape. For us, this results in the scale factor being 2.

Now, the similar side to r is side ED. We need to divide 7.5 by 2 to find r.

When doing so, we get r to be 3.75.

Answer:

Step-by-step explanation:

The common difference of an arithmetic sequence is the slope of the equation that describes it. The slope formula is useful in this case:

  m = (y2 -y1)/(x2 -x1)

  m = (219 -213)/(4 -2) = 6/2 = 3

The common difference of the corresponding arithmetic sequence is 3.

Answer:

39 units

Step-by-step explanation:

area of polygon = area of rectangle VERD + area of triangle MVR

[length of rectangle (6) * width of rectangle (5)] + [1/2 * 3 (height of triangle) * 6 (height of triangle)] = area of polygon

(6*5) + (1/2*3*6) = area of polygon

30 + 9 = area of polygon

area of polygon = 39

Answer:

Step-by-step explanation:

This is arithmetic since adding 4 to each term gets us to the next term in the sequence. That means that the common difference, d, is 4. The general arithmetic explicit formula is

[tex]a_n=a_1+d(n-1)[/tex] and using the info given when a1 = 3 and d = 4:

[tex]a_n=3+4(n-1)[/tex] or, if you want to make it easier to deal with:

[tex]a_n=4n-1[/tex] (I just distributed through the parenthesis and then combined like terms. As you can see, arithmetic sequences are linear).
