Answer:
The number cubes needed when we have three cubes along each edge is 27 cubes
Step-by-step explanation:
The given parameters for the building of a cubic prism are;
The number of cubes used to build the 2 by 2 cube = 8 cubes
Let 'x' represent the length of each cube, we have;
The volume of a 2 by 2 cube = 2·x × 2·x × 2·x = 8·x³
Where x³ represents the volume of each cube
When we have three cubes along each edge, the total volume, becomes;
V = 3·x × 3·x × 3·x = 27·x³
The number cubes needed when we have three cubes along each edge, n = (The total volume of the cubes)/(The volume of each cube)
∴ The number cubes needed when we have three cubes along each edge, n = 27·x³/(x³/cube) = 27 cubes.
Can someone please help Im very confused
As the h(t) shows, the number before the 't' is the height, or meters represented by the small rocket traveling in the air.

A researcher conducts two studies on child health. In Study 1, 30 children consume either a low, moderate, or high-fat meal (n=10 per group). In Study 2, the researcher conducts the same study, except that a No Meal control group is added, with n = 10 in each group. If Fobt = 3.11 in both studies, then in which study will the decision be to reject the null hypothesis at a .05 level of significance for a one-way between-subjects ANOVA?
Answer:
The answer is "Study 2"
Step-by-step explanation:
In Study 2:
[tex]k =group\ number = 4\\\\df_1 = k - 1 = 4 - 1 = 3\\\\N = Total\ observations \ numbers = 30 + 10 = 40\\\\df_2 = N - k = 40 - 4 = 36\\\\Critical \ value( \alpha) (0.05,3,36) = 2.866\\\\Decision\ Rule\ in \ F \ test > F \critical, \ Then \ Reject H_0\\\\F \ test \ (3.11) < F \ critical \ (2.866)\\\\ \therefore H_0 \ is\ reject\\\\[/tex]
Find the surface area of the cone. Use 3.14 for π.
Answer:
S.A. = 138.16
Step-by-step explanation:
S.A. = πrl+πr²
3.14 x 4 = 12.56
12.56 x 7 =87.92
3.14 x 4 = 12.56
12.56 x 4 = 50.24
87.92 + 50.24 = 138.16

Franklin treated his sister to lunch while visiting her in Ashland. Their lunch cost $75, and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the $75, how much in total did he pay?
Answer:
$96
Step-by-step explanation:
If you doing ixl M.10 Multi-step problems with percents
i did this question and it's 96.hope this helps
Total cost of pay for the lunch will be $96.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The cost of lunch = $75
Sales tax = 8%
Tip = 20%
Now,
The cost on sales tax = 8% of $75
= 8/100 x 75
= $6
Thus, The cost on sales tax = $6
And, The cost for tip = 20% of $75
= 20/100 x 75
= $15
Thus, The cost for tip = $15
So, Total cost to pay for lunch = $75 + $6 + $15
= $96
Thus, Total cost of pay for the lunch will be $96.

Rebecca supplies costumes to a number of theater companies and recently lent out a number of different hats. turbans 6 berets 3 mortarboards 3 top hats 2 What is the experimental probability that the next hat requested from Rebecca's inventory will be a turban? Write your answer as a fraction or whole number.
Using it's concept, it is found that the experimental probability that the next hat requested from Rebecca's inventory will be a turban is of [tex]\frac{3}{7}[/tex].
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, these number of outcomes are taken from previous trials.
In this problem, out of 14 items, 6 were turbans, hence:
[tex]p = \frac{6}{14} = \frac{3}{7}[/tex]

Ok so if u go to the very bottom of the world will u be in all the time zones???
Answer:
That would be impossible because you would get melted by the earth core
Step-by-step explanation:
When you say bottom of the world, I'm assuming you mean the middle or the core. Like the other answer said, I'd just die. BUT if I didn't die, then yes, I think I'd be in all the time zones. :) Or I just wouldn't have a sense of time.
We tell time based on how much sunlight we get, so would that mean it would be midnight forever?

Your friend earns 7x dollars for
working x hours. How much does
your friend earn for working
16 hours? 40 hours?
16 hours $
40 hours $
Answer:
$112 for 16 hours
$280 for 40 hours
Step-by-step explanation:
Well, given that if 7x dollars are earned working for x hours (x is assumed to be 1), then $7 are earned for every hour worked. So we can pretty much multiply $7 (Money earned per hour) by 16 and then 40 (Hours worked). 7*16=112, and 7*40=280. And there are your two answers.
