Sean paints 8/15 of a fence in 1 hour. He paints 3/10 of the fence less in the second hour. What fraction of the fence did he paint in two hours? Did he finish the job in two hours? plsss help
show work
Answer:
Sean didn't finish the job. He painted 23/30 of the fence in two hours.
Step-by-step explanation
He didn't finish the job because 23/30 is not finished. It isn't finished because Sean is less than 23/30 of the way done. That doesn't seem done to me.
I got the fraction 23/30 by looking at the problem carefully. He painted 3/10 of the fence "less" than the first hour which was 8/15 of the fence. So that means we have to subtract 8/15 and 3/10 to get 7/30.
Now, we just figured out how much Sean painted in the second hour, and the question is asking what fraction of the fence did he paint in BOTH hours. Meaning we have to add the first and second hour to get the answer of 23/30.
Hope this helped! Have a great day!
No, he did not finish his job.
What is fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given, Sean paints 8/15 of a fence in 1 hour,
Sean paints 3/10 part less in the second hour So, fraction he paints in the second hour = 8/15-3/10 = 16-9/30 = 7/30
So,
Paint in 2 hours = 8/15+7/30 = 16+7 / 30 = 23/30
Hence, he did not finish his job.

Ice cubes trays each contain 12 cubes of ice. If t represents the number of trays, and c
represents the number of cubes, find an equation that relates t and c.
Answer:
c = 12 * t
Step-by-step explanation:
The only equation that relates t and c would be the following...
c = 12 * t
This is because the total number of cubes that exist depends on how many available trays exist. Therefore, creating a positive correlation relationship between these two variables. Since each tray contains 12 cubes, 12 is therefore multiplied by the number of trays to get the total number of cubes. This means that the more trays available the more cubes that are created.

Evaluate the function for x = 3.5 f(x)=[2.5x]
a 8.75
b 8
c 9
Answer:
The correct option is a. 8.75.
Step-by-step explanation:
Given:
f(x)=[2.5x] .............................. (1)
Where;
x = 3.5
The function can be evaluated by substituting x = 3.5 into equation (1), we have:
f(3.5) = 2.5 * 3.5
f(3.5) = 8.75
This implies the value of the function is 8.75. Therefore, the correct option is a. 8.75.
Y is inversely proportional to the square of x. If Y = 3 when x = 3, then Y =
ş, when x is
?
Answer:
It will be same the value of second Y
Answer:
y = [tex]\frac{27}{x^2}[/tex]
Step-by-step explanation:
Assuming you require the equation of proportion.
Given y is inversely proportional to x² , then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex]
To find k use the condition if y = 3, then x = 3, that is
3 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
27 = k
y = [tex]\frac{27}{x^2}[/tex] ← equation of proportion

Answer:
y = -4x + 17
Step-by-step explanation:
Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.

A website lists homes for sale in a suburban town. The site provides information including neighborhood, selling
price, age of the home in years), number of bedrooms, and whether the home has a garage. Which of the variables
is a categorical variable?
neighborhood
selling price
age of the home
number of bedrooms
Answer:
neighborhood
Step-by-step explanation:
Variables can be classified as categorical(qualitative) and quantitative.
Categorical variables:
Its variables are labels(for example, good/bad, yes/no,...)
Quantitative variables:
It's variables are numbers.
In this question:
The only variable which the answer is a label is the neighborhood. So this is the answer.

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 5.9 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 160 engines and the mean pressure was 6.0 pounds/square inch. Assume the variance is known to be 0.36. A level of significance of 0.05 will be used. Determine the decision rule.
Answer:
Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance
There is a difference between the means
Step-by-step explanation:
Step(i):-
Given that mean of the Population = 5.9pounds/square inch
Given mean of the sample = 6.0pounds/square inch
Given that variance of the Population = 0.36
The standard deviation of the Population = √0.36 =0.6
critical value (Z₀.₀₅)= 1.96
Step(ii):-
Null Hypothesis:H₀: x⁻ = μ
Alternative Hypothesis:H₁: x⁻ ≠ μ
Test statistic
[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{6.0-5.9 }{\frac{0.6}{\sqrt{160} } }[/tex]
Z = 2.1097
Final answer:-
Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance
The null hypothesis is rejected
There is a difference between the means

Explain how to compare decimals use the numbers 6.75 and 6.732 to help you explain this process
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732
