Explain why each non-zero integer has two square roots but only one cube root.

Answers

The square root of a number is a value that when multiplied by itself it gives the number. For example: 4x4=16, so a square root of 16 is 4. This is why each integer has two square roots. The cube root of a number is a special value that, when used is a multiplication three times,gives that number

In a hotel building, the lobby is located at sea-level. The first floor is located 18 feet above the lobby, and the basement is located 22 feet below the lobby.

a. Write an inequality to compare the elevations of the first floor and the basement.

b. What is the distance from the lobby to the basement? Write your answer as an absolute value statement.

c. Which is a greater distance from the lobby: the first or basement? Justify your response.

Answers

9514 1404 393

Answer:

-22 < 0|-22-0| = 22distance to basement is greater

Step-by-step explanation:

a) If we let B, L, F represent the elevations of the basement, lobby, and first floor, respectively, then we have ...

  B = -22

  L = 0

  F = 18

Your inequality could be either of ...

  B < L

  -22 < 0

__

b. We're not sure exactly the form you're looking for. Use whichever absolute value statement is appropriate to your needs.

  distance = |B -L| = |-22 -0| = |-22| = 22

__

c. The distance from the lobby to the first floor is |18 -0| = 18.

The distance from the lobby to the basement is |-22-0| = 22.

The distance 22 is greater than the distance 18, so the distance to the basement is greater.

_____

Additional comment

The difficulty with this question is not figuring out whether -22 is farther from 0 than is +18. The difficulty is in figuring out the form of the answer that is expected. Without looking at your curriculum materials, we cannot even make an appropriate guess.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. The temperatures of eight different plastic spheres.

Answers

The level of measurement that is most appropriate for the temperatures of eight different plastic spheres is the interval scale.

An interval scale shows magnitude and order. It shows numerical difference between values on same scale which are distinguished and are equal.

One common property of the interval scale is that it has an arbitrary zero point which is perfectly exhibited by the temperature measurement. This implies that the scale of measurement has no zero point because zero on the Centigrade scale is 32 degrees on the Fahrenheit scale.

Therefore, temperature measurement of eight different spheres can be regarded as an interval scale.

Triangle ABC is similar to triangle DEF with a ratio of 3/5 If the difference of their
perimeters is 40 inches, find the perimeter of each triangle.

Answers

9514 1404 393

Answer:

ΔABC -- 60 inchesΔDEF -- 100 inches

Step-by-step explanation:

If P is the perimeter of the larger triangle, then 3/5P will be the perimeter of the smaller one. The difference in perimeters is ...

  P -3/5P = 40 in

  2/5P = 40 in

  P = (5/2)(40 in) = 100 in

  3/5P = 3/5(100 in) = 60 in

The smaller triangle perimeter is 60 in; the larger is 100 in.

Answer:

  y -2 = 1/4(x +3)

Step-by-step explanation:

Process: find the negative reciprocal of the slope of the line shown and put the appropriate values into the point-slope equation.

__

The slope of the given line can be found as the ratio of rise to run between the marked points.

  m = rise/run = -8/2 = -4 . . . . counting grid squares

The desired line has a slope that is the opposite reciprocal of this:

  m' = -1/m = -1/-4 = 1/4

The point-slope equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Then the desired line with slope 1/4 through point (-3, 2) has equation ...

  y -2 = 1/4(x +3)

A summer camp has 372 campers who will be going on an outing. Estimate the number of vans needed to accommodate the entire camp if each van can comfortably hold 12 passengers. Then calculate the actual number of vans that will be needed

Answers

Answer:

31

Step-by-step explanation:

You divide, 372 divided by 12

the actual number of vans needed is 31 vans to accommodate the entire camp. To estimate the number of vans needed to accommodate the entire camp, we can use the concept of rounding up to the nearest whole number.

The number of vans required will be the total number of campers divided by the capacity of each van (12 passengers), rounded up to the nearest whole number.

Estimate:

Number of vans needed =[tex]\(\frac{372}{12}\)[/tex](rounded up to the nearest whole number)

[tex]\(\frac{372}{12} \approx 31\)[/tex]

So, the estimate suggests that around 31 vans will be needed to accommodate the entire camp.

To calculate the actual number of vans needed, we can use the exact division without rounding up.

Actual number:

Number of vans needed = [tex]\(\frac{372}{12} = 31\)[/tex] vans

Thus, the actual number of vans needed is 31 vans to accommodate the entire camp.
