Step-by-step explanation:
First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.
Question 17
Using a calculator, you get 6.48074069… for your decimal.
Rounding it to the nearest tenth, your answer would be 6.5
Now, to find the two consecutive whole numbers the square root is between…
However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.
Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!
Question 18
Using a calculator, you get 9.380833151… for your decimal.
This rounds to 9.4
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.
In non-decimal form (simplified radical), your answer can be 2√22.
Question 19
Using a calculator, you get 7.93725393… for your decimal.
This rounds to 7.9
The whole numbers surrounding this decimal are 7 and 8.
You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.
In non-decimal form (simplified radical), your answer can be 3√7.
Question 20
Using a calculator, you get 8.66025403… for your decimal.
This rounds to 8.7
The whole numbers surrounding this decimal are 8 and 9.
You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.
In non-decimal form (simplified radical), your answer can be 5√3.
Question 21
Using a calculator, you get 5.47722557… for your decimal.
This rounds to 5.5
The whole numbers surrounding this decimal are 5 and 6.
You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.
Question 22
Using a calculator, you get 9.84885780… for your decimal.
This rounds to 9.8
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.
Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.
Hope that helps! <3

First Person who gets it right and EXPLAINS will get branliest! :-)
Answers
5 is the answer.
Review:What is a cuboid?
A cuboid is a rectangle, but in 3D form.
Do we calculate area or volume in a cuboid?
We calculate the volume for 3D shapes. For 2D shapes, area is used.
If/Then:
Now, if the volume of the cuboid is 24 units³ then:
x × x × y
Now, lets fit all our options to see which one is NOT the dimensions.
Option A:
x × x × 3 = 24 units³
x × x = 12 units³ ✔
This is possible.
Option B:
x × x × 4 = 24 units³
=> x × x = 6 units³ ✔
This is possible.
Option C:
x × x × 5 = 24 units³
=> x × x = 24/5 units³ ❌
This is not possible. This will be our answer.
Option D:
x × x × 6 = 24 units³
=> x × x = 4 units³✔
This is possible.
Conclusion:
So after working on our problem, we can conclude that C is our answer. Hoped this helped.

Use the table to answer the following questions.
Time (hours) Distance (miles)
2 90
3 135
5 225
6 270
1. Find the constant of proportionality.
2. Use the constant of proportionality to write a unit rate for the data in the table.
3. Write an equation to represent the relationship between time, t, and distance, d.
Answers
Answer:
Sure, here are the answers to your questions:
The constant of proportionality is 45. This is because the ratio of distance to time is always 45. For example, 90/2 = 45, 135/3 = 45, 225/5 = 45, and 270/6 = 45.
The unit rate is 45 miles per hour. This is because the constant of proportionality is 45, and the units of time are hours and the units of distance are miles.
The equation that represents the relationship between time, t, and distance, d, is d = 45t. This is because the constant of proportionality is 45, and the equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality.
Here are the steps that I used to solve the problem:
I first looked at the table and noticed that the ratio of distance to time was always the same. This is a clue that the relationship between distance and time is proportional.
I then calculated the constant of proportionality by dividing the distance by the time for each pair of values. For example, I divided 90 by 2 to get 45, 135 by 3 to get 45, 225 by 5 to get 45, and 270 by 6 to get 45.
I then used the constant of proportionality to write a unit rate. The unit rate is the constant of proportionality divided by the units of time. In this case, the constant of proportionality is 45 and the units of time are hours. Therefore, the unit rate is 45 miles per hour.
I then used the constant of proportionality to write an equation. The equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality. In this case, the constant of proportionality is 45, so the equation is d = 45t.

Alicia was stacking unit cubes with side lengths of 12 inch to make a larger cube, but she did not have time to finish. If she used the given length, width, and height of the stack so far, what will be the volume of Alicia′s cube when it is finished?
Answers
Cube, length= 12in (cubes are the same length on each side)
So 12•12•12
= 1,728in for just 1 cube
Volume of 1 cube=1,728in(cubed)
Im assuming that a bigger cube would be 4 cubes together or 8 cubes.
So for 4 cubes together it would be 1,728•4 = 6,912in(cubed)
For 8 cubes together it would be
1,728•8= 13,824in(cubed)

If a widget factory as a fixed operating cost of $2,500 per day plus a cost of $1.50 per widget produced. If a widget sells fro $5.00, what is the least number of widgets that must be sold per day to make a profit?
Answers
Answer:
At least 714 numbers of widgets must be sold per day to make a profit.
Given fixed operating cost = $2,500 per day cost of widget =$ 1.50
widget sells =$ 5.00
Cost function = C(X)=1.50x+2500
Revenue function = R(X)=5 x
At Break Even point R (X) = C (X)5
X= 1.50X+2003.5
X =2500X =714
Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
