Answer:
15
Step-by-step explanation:
The amount of water displacement would be equivalent to the volume of the rock, which is 1800. We find this by doing 10 x 12 which is 120. Now we can divide 1800 by 120, which is 15. Giving us the dimensions 10 x 12 x 15.

Step-by-step explanation:
Answer:
11.5
Step-by-step explanation:
you have to use this equation to solve it [r = (1/t)(A/P - 1)] and basically just plug the numbers in to get 11.5. (you could also use one of those online calculators)
r = (1/2)((4920/4000) - 1) = 0.115
r = 0.115
The areas of two similar triangles are 18cm^2 and 8cm^2. One of the sides of the first triangle is 4.5cm. What is the length of the corresponding side of the other triangle? Please answer ASAP!!! Thank you!!!
Answers
Answer:
3 cmStep-by-step explanation:
The area is the product of two dimensions, therefore the scale factor is:
A/A' = (b*r*h*r)/(b*h) = r²r² = 18/8r = √9/4 = 3/2 = 1.5The length of the corresponding side will be:
a/a' = ra' = a/ra' = 4.5 / 1.5 a' = 3 cmfill in the boxes to show two ways you can find 8+6

The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min. If one such class is randomly selected, find P54
Answers
Answer:
52.6704
Step-by-step explanation:
The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min
Let x = 49.29, y=55.55
Percentile(P) = 54/100 = 0.54
P54 = x+(y-x)p
P54 = 49.29 + (55.55-49.29)*0.54
P54 = 49.29 + 6.26*0.54
P54 = 49.29 + 3.3804
P54 = 52.6704

A woman purchased a used car for $3,000. She decided to sell the car for 20% above her purchase price. She could not sell the car so she reduced asking price by 20%. If she sells the car at the reduced price, she will have a profit or a loss or will she break even?
10.1 #17
Answers
Answer:
She will have a loss of $ 120
Step-by-step explanation:
Purchase price of car = $ 3000
20% of 3000 = [tex]\frac{20}{100}*3000[/tex]
= 20 * 30
= $ 600
Selling price = 3000 + 600 = $ 3600
Reduction price = 20% of 3600
[tex]\frac{20}{100}*3600[/tex]
= 20 * 36
= $ 720
Current selling price after reduction = 3600 - 720
= $ 2880
Loss = 3000 - 2880
= $ 120
3000x20%=600. Which is above her purchase price total 3600 and she couldn’t sell.
She reduced the asking price(3600) by 20%
Which would -600. Now she’s asking 3000 what she paid.

a manufacturer says that the diagonal measurement of a laptop computer is 16 inches. Find the relative error of this measurement to the nearest tenth.
A. 0.6%
B.1.6%
C.3.1%
D.6.3%
Answers
Answer:
As this is incomplete, it lacks the value of actual error.
Here, we do not know the actual value. so let's assume it is 1 inch
Relative Error = 6.25 % ≈ 6.3% = D
Step-by-step explanation:
As this is incomplete, it lacks the value of actual error.
We are asked to calculate the relative of the measurement.
Relative error formula = Actual error/Measurement x 100
Here, we do not know the actual value. so let's assume it is 1 inch
Actual value = 1 inch
Measurement = 16 inch
Relative Error = 1/16 x 100
Relative Error = 6.25 % ≈ 6.3% = D
D. 6.3%
A publisher reports that 55% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 280 found that 51% of the readers owned a laptop. Make the decision to reject or fail to reject the null hypothesis at the 0.05 level.
Answers
Answer:
We fail to reject the null hypothesis, we accept H₀
Step-by-step explanation:
Population proportion p₀ = 55 % p₀ = 0,55
Sample size n = 280
Sample mean p = 51 % p = 0,51 q = 0,49
n*p and n*q are both bigger than 10 therefore we can approximate the binomial distribution to a normal distribution
Test Hypothesis
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p ≠ p₀
Significance level is α = 0,05 but we have a two-tail test then
α/2 = 0,025
z(c) = - 1,96
Computing z(s)
z(s) = ( p - p₀ ) / √(p*q)/n
z(s) = ( 0,51 - 0,55 ) / √(0,51*0,49)/280
z(s) = - 0,04 * 16,73 / 0,5
z(s) = - 1,34
Comparing
z(s) and z(c)
- 1,34 < - 1,96
| z(s) | < | z(c)|
Then z(s) is in the acceptance region, we accept H₀

Usually Holly leaves home to school at 9:00, however today she left home 20 minutes later. In order to be at school on time she increased her usual speed by 20% and still was at school 15 minutes later than usual. What is her usual time from home to school
Answers
Answer:
Her usual time from home to school is 30 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Here, we want to calculate the normal time she spent going from home to school
Let the normal time be x minutes
And the normal speed be t m/min
Today, she increased her speed by 20%
Her speed today will be t + 20/100 * t =
1.2t m/min
Her distance from how to school normally is
xt meters
Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier
What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes
So, the time spent on her increased speed journey is;
(x-5) minutes
At any point in time, the distance will be equal;
Thus, mathematically;
xt = 1.2t(x-5)
xt = 1.2xt - 6t
6t = 1.2xt-xt
6t = 0.2xt
t cancels out
0.2x = 6
x = 6/0.2
x = 30 minutes
