The surface area of the barn is 2040 square feet.
What is a rectangle?A rectangle is a plane shape with four sides and four right angles.
Analysis:
The barn is composed of:
Two straight long rectangles with dimensions = 10ft x 40ft
Two slant rectangles with dimensions = 10.6ft x 40ft
Two short rectangles with dimensions = 10ft x 14ft
Two triangles, height 8ft and base 14feet
The surface area of barn = 2(10x40) + 2(10.6 x 40) + 2(1/2 x 14 x 8) + 2(10 x 40) = 800 + 848 + 112 + 280 = 2040 square feet
In conclusion, the surface area of the barn is 2040 square feet.

Grant plans to evaporate enough water from 22 gallons of a 16% ammonia solution to make a 24% ammonia solution. Which equation can he use to find n, the number of gallons of water he should remove?
3.52 (22 minus n) = 0.24
StartFraction 22 minus n Over 3.52 EndFraction = StartFraction 24 Over 100 EndFraction
StartFraction 3.52 Over 22 minus n EndFraction = StartFraction 24 Over 100 EndFraction
3.52 + (22 minus n) = 0.24
Answers
The equation that he can use to find n, the number of gallons of water he should remove is; (3.52)/(22 - n) = 24/100
How to Calculate Chemical quantities?Let us first find the amount of ammonia in 22 gallons of 16% ammonia solution.
This gives;
Amount = 16% * 22 gal
Amount = 3.52 gal
Now, the amount of ammonia remains the same after the water evaporates, but the total amount of solution will reduce by the amount of water that evaporates.
Amount of ammonia = 3.52 gal
Amount of water that remains = 22 - n
Desired concentration = 24% = 24/100
Thus, the equation is;
(3.52)/(22 - n) = 24/100

The diameter of a circle is 36 meters. What is the circle's area? Use 3.14 for .
Answers
Answer:
1017.36 m²
Step-by-step explanation:
Info:
Diameter: 36m
π: 3.14
---
If the formula for area of circle is: A = πr², and the radius is 18 (half of 36)
Then to find the area, we just multiply π with 18².
18 x 18 = 324.
324 x 3.14 = 1017.36
The area of the circle is 1017.36 m²
Hi Student!
The first step to most problems is to determine the important information that is provided in the given problem statement. In this problem we can see that we are given a diameter of a circle which is 36 meters. Another important thing that we can determine is that the question is asking for us to find the area of the circle using 3.14 for π.
Now that we have collected our important information we can move onto the next step which isn't to find the area yet. First, we need to determine what the radius of our circle is.
Determine the radius
[tex]radius=\frac{diameter}{2}[/tex][tex]radius=\frac{36\ m}{2}[/tex][tex]radius=18\ m[/tex]Now, we can finally plug in our values into the area of a circle equation and solve. The only thing that we need to find the area is the radius which we determined from the previous step.
Plug in the values
[tex]area = \pi * radius^2[/tex][tex]area = 3.14 * (18\ m)^2[/tex]Expand the exponent
[tex]area = 3.14 * (18\ m * 18\ m)[/tex][tex]area = 3.14* 324\ m^2[/tex]Multiply the final two numbers
[tex]area = 1017.36\ m^2[/tex]Therefore, the area of a circle with a diameter of 36 meters is 1017.36 meters squared.

Calculate the distance between the points (7, 4) and (-5, -3).
Answers
Answer:
D = √193 units
or
D = 13.892 units
Step-by-step explanation:
Given:
(7, 4) and (-5, -3)
Calculate the distance
Solution:
[tex] \rm \: Distance (D) = \sqrt{( x_{2} - x_{1}) {}^{2} + (y_{2} - y_{1) {}^{2} }} [/tex]
Now, substitute the values given:
[tex] \rm \: D = \sqrt{ \{( - 5) - 7 \}^{2} + \{( - 3) - 4 {}^{} \} {}^{2} } [/tex]
[tex] \rm \: D = \sqrt{ \{12 \}^{2} + \{( - 3) - 4 {}^{} \} {}^{2} } [/tex]
[tex] \rm \: D = \sqrt{ 144 + \{( - 3) - 4 {}^{} \} {}^{2} } [/tex]
[tex]\rm D = \sqrt{144 + \{ 7\}{}^{2} } [/tex]
[tex] \rm \: D = \sqrt{144 + 49} [/tex]
[tex] \boxed{\rm \: D = \sqrt{193}} [/tex]
[tex] \boxed{\rm \: D =13 .892}[/tex]
Thus, Distance between the two given points will be √193 or √13.892 units.
Answer:
[tex]\bf \sqrt{193}[/tex] units or 13.9 units is the distance.

An experiment was conducted to test the effect of a new cholesterol medicine. Fifteen people were treated with medicine X and 15 with medicine Y for a month; then the subjects' cholesterol level was measured. A significance test was conducted at the α = 0.01 level for the mean difference in cholesterol levels between medicine X and medicine Y. The test resulted in t = 2.73 and p = 0.003. If the alternative hypothesis in question was Ha: μX − μY ≠ 0, where μX equals the mean cholesterol level for subjects taking medicine X and μY equals the mean cholesterol level for subjects taking medicine Y, what conclusion can be drawn?
Answers
Considering the hypothesis tested and the p-value of the test, the correct option is given by:
There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.
What are the hypothesis tested?At the null hypothesis, it is tested if there is no difference between the cholesterol levels, that is:
H₀:Hₓ-H
At the alternative hypothesis it is tested if there is a difference, hence:
H₀:Hₓ-H≠0
The p-value is of 0.003 < 0.01, hence we reject the null hypothesis and conclude that there has was a difference, hence the correct option is given by:
There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.
