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.
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

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]

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.

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.

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?

at a rate of 1.25 inches per hour and after 5 hours, there are 6 inches of rain in the
gauge.
How much rain will be in the gauge in 11 hours
Answer:
13.5 inches
Step-by-step explanation:
after 5 hours = 6 inches
11 - 5 = 6 hours to go
1.25 x 6 = 7.5 inches
7.5 + 6 = 13.5 inches
