Step-by-step explanation:
there is nothing "following" here.
however, if I understand correctly, we need a 15% increase to 60 kV.
100% = 60 kV
1% = 100%/100 = 60/100 = 0.6 kV
15% = 1% × 15 = 0.6 × 15 = 9 kV
so, adding these 15% gives us
60 + 9 = 69 kV.
once we understand this mechanism, we can also use the shortcut : to add x% to something, we need to multiply this something by 1.x.
in our case, we want to increase 60kV by 15% ?
the result is
60 × 1.15 = 69 kV
simply because (as the top part should have shown too) x% of the whole = x/100 × whole.
so, to add x% means to have
100/100 × whole + x/100 × whole = 1.x × whole

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
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

Answer:
My best Gues is x=0 and x=6
Step-by-step explanation:
Because The zeroes of a function is where the line is equal to fx=0 which means it is where the line intercepts with the x axis. And the the line is on the x- axis touching 0 and it isn’t touching any negative number so it would have to be positive and would be 6.

The diameter of a circle is 36 meters. What is the circle's area? Use 3.14 for .
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.

What is ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called focus adds up to a constant. It is taken from the cone by cutting it at an angle.
We have equation of ellipse:

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?
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.

Calculate the distance between the points (7, 4) and (-5, -3).
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.
