1. We assume, that the number 110.2 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 110.2 is 100%, so we can write it down as 110.2=100%.
4. We know, that x is 17.7% of the output value, so we can write it down as x=17.7%.
5. Now we have two simple equations:
1) 110.2=100%
2) x=17.7%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
110.2/x=100%/17.7%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 17.7% of 110.2

110.2/x=100/17.7
(110.2/x)*x=(100/17.7)*x - we multiply both sides of the equation by x
110.2=5.64971751412*x - we divide both sides of the equation by (5.64971751412) to get x
110.2/5.64971751412=x
19.5054=x
x=19.5054

now we have:
17.7% of 110.2=19.5054

A cylinder has a height of 7 in. and a diameter of 6 in. What is the volume of the cylinder to the nearest cubic inch? V = 66 in
Natalija [7]

Answer:

The answer is

<h2>V = 198 in³</h2>

Step-by-step explanation:

Volume of a cylinder = πr²h

where

h is the height

r is the radius

From the question

h = 7 in

To calculate the radius from the diameter we use the formula

radius = diameter/2

From the question

diameter = 6

radius = 6/2 = 3 in

Volume of the cylinder is

(3)²(7)π

= 9(7)π

= 63π

= 197.9203

We have the final answer as

<h3>V = 198 in³ to the nearest cubic inch</h3>

Hope this helps you

The temperature at 6:00 pm was 24°. At midnight the temperature 36° lower than 6:00pm . What was the temp at midnight?
horrorfan [7]

Answer:

-12°

Step-by-step explanation:

Man... I just did 36 minus 24, and since it says 36° lower I decided it was -12 degrees (24 - 36 is more accurate but I find it easier just to do it the other way)

The highest score of the women’s basketball championship was Jessica Bradley. She scored 147 more points and Tina Hardtner her t
Rufina [12.5K]

Answer:

MAKE MY ANSWER BRILLINEST PLEASE:)

Step-by-step explanation:

LET:

j = the points that Jessica scored

t = the points that Tina scored

Jessica scored 147 more points than Tina:

j = t + 1497

Together, Bradley and Harner scored 1601 points:

j + t = 1601

by solving the system of equations:

j = t + 147

j + t = 1601

we find

j = 856 points

t = 707 points

Jessica Bradley scored 856 point.

Tina Harner scored 707 points.

In tests for intoxication, blood alcohol levels are expressed as percentages by volume. A blood alcohol level of 0.080% by volum
GaryK [48]

Answer:

The required volume is 5 ml.

Step-by-step explanation:

Given : In tests for intoxication, blood alcohol levels are expressed as percentages by volume. A blood alcohol level of 0.080% by volume means 0.080 mL of ethanol per 100 mL of blood and is considered proof of intoxication. If a person's total blood volume is 5.0 L.

To find : What volume of alcohol in the blood gives a blood alcohol level of 0.100 % by volume?

Solution :

According to question we use the formula,

\text{Present Volume}=\dfrac{\text{Vol}_{\text{Alcohol}}}{\text{Vol}_{\text{total}}}\times 100\%

The percentage of a blood alcohol level is 0.100%

The total volume of the blood is V=5L=5000 ml.

Substitute the value in the formula,

0.100=\dfrac{\text{Vol}_{\text{Alcohol}}}{5000}\times 100

\frac{0.100}{100}=\dfrac{\text{Vol}_{\text{Alcohol}}}{5000}

\text{Vol}_{\text{Alcohol}}=\frac{0.100\times 5000}{100}

\text{Vol}_{\text{Alcohol}}=5

Therefore, the required volume is 5 ml.
