The formula for the volume of a cylinder is V = xrh. The cylinder to the right has an exact volume of 720x cubic
meters. Find its height.
.6 m
The height of the cylinder is
(Simplify your answer.)
Answer:
You have the formula wrong.
The volume of a cylinder = PI * radius^2 * height
To find the height, the formula is:
height = volume / (PI*radius^2)
I'm assuming the radius = .6 meters so
height = 720 / (3.14159265 * .6^2)
height = 720 / 1.130973354
height = 636.61977 meters

5.) Your printer takes 36 seconds to print a small photo and 60 seconds to print a large one.
a.) Write an expression for the time (in seconds) your printer would take to print a batch
including both small and large photos.
Answer:
[tex]36s+60l[/tex]
Step-by-step explanation:
Let [tex]s[/tex] be the amount of small photos your printer needs to print.
Let [tex]l[/tex] be the amount of large photos your printer needs to print.
Since it takes 36s to print a small photo and 60s to print a large photo, we can form the expression: [tex]36s+60l[/tex]

Find cos(a) Reduce the ratio if necessary
Answer:
3/5 Choice 4.
Step-by-step explanation:
Remember SOH, CAH, TOA.
Sine=opposite/hypotenuse
Cosine=Adjacent/hypotenuse
Tangent=Opposite/adjacent.
Since we are looking for Cosine, we would need to locate the adjacent and hypotenuse of angle a.
The hypotenuse is the easiest to find because that will simply be the longest side of the triangle(50)
The adjacent would be 30 because 40 is the opposite(right across from theta).
So, A=30
H=50
Simply that to get Cos(A)=[tex]\frac{3}{5}[/tex].

please show work 7r + 21 = 49r
Answer:
1/2 = r
Step-by-step explanation:
7r + 21 = 49r
Subtract 7r from each side
7r-7r + 21 = 49r-7r
21 = 42r
Divide each side by 2
21/42 = 42r/42
1/2 = r
Answer:
r = 0.5
Step-by-step explanation:
First you need to isolate the r variable.
7r + 21 = 49r
-7r -7r
21 = 42r
Then Divide both sides by 42
0.5 = r
Now check your answer by inserting it back into the original equation.
7(0.5) + 21 = 49(0.5)
3.5 + 21 = 24.5
24.5 = 24.5
The equation is true so r = 0.5

One of the legs of a right triangle measures 1 cm and the other leg measures 17 cm.
Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answer:
using phythagoras formula of right angles we can calculate the hypotenuse
1^2=x^2+17^2
x^2=17^2-1^2(transpose)
×^2=288 (introduce a square root)
x=15.01(round of to the nearest tenth)
Step-by-step explanation:
x=10
The measure of the hypotenuse is 17.029
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have Pythagoras theorem:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
Given;
The legs of a right triangle measures 1 cm
The other leg measures 17 cm
Now,
|AC|^2 = |AB|^2 + |BC|^2
|AC|^2 = |1|^2 + |17|^2
|AC|^2 = 1 + 289
AC=17.029
Therefore, by pythagoras theorem answer will be 17.029.

How do I do this? I need help really bad. Can someone help me with this question?
Answer:
Step-by-step explanation:
It seems like there is only one question. I'll answer that first and then we'll discuss what might be inferred from the introduction.
1)
The way the problem is set up you get a factoring to take place
(x^3 - 8) = (x - 2)(x^2 + 2x + 4)
================
(x - 2)
This question is unique. They expect you to cancel, which leaves you with y = x^2 + 2x + 4) which is a quadratic.
The reason you don't put in x = 2 is because technically, you get 0/0 which can be shown to be either 1 or 0. To get out of that, we say that 0/0 is undefined. The graphing program has taken the stance that 0/0 is 1. However I wouldn't really accept that. The whole problem comes down to 0/0 which is undefined.
Which statements include two quantities in the real world that are additive inverses?
Select each correct answer.
1. Daniella overdraws her account by $70 and then deposits $100 in the account.
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
3. A lithium ion has 3 positively charged protons and 2 negatively charged electrons.
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
There are two statements here, showing quantities in real world which are additive inverse of each other :
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
here, we can depict going up as +2 miles and going down the trail as -2
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .
Answer:
The options are (2) and (4).
Step-by-step explanation:
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
→ Up 2 mi (+2) and down 2 mi (-2).
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
→ Here they are, ascends 2000 ft (+2000) and descends 2000 ft (-2000).
For three consecutive years the cost of gasoline increased by 8%, 15%, and 20%, respectively. What was the overall percentage increase of the cost of gasoline during the three-year period?
Answer: 24.84%
Step-by-step explanation:
I don't really know how to explain step-by-step from my messy notes
The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.
What is percentage?A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.
The given percentage are,
8%, 15%, and 20%.
Now to find the overall average increase we need to find the average percentage for three consecutive years.
overall average = sum of all the percentage/number of percentage
overall average = 8%+15%+ 20%/3
overall average = 43%/3
overall average = 14.33%
Hence,The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

there was a vote at a local school to determine a new logo. You are told 7% of the students wanted to keep the old logo, and that 7% represents 1,400 students at the school. how many students are at the school?
Step-by-step explanation:
Let the number of students be x,
Now,
7% of x = 1400
or, 7/100 X x = 1400
or, x = 1400 x 100
—————
7
or, x = 140000/ 7
or, x = 20000

find slope that is perpendicular to the line 4−2=12 ?
Answer:
m = -1/2
Step-by-step explanation:
4 − 2 = 12
= −2 = 12 − 4
= = (12 − 4) ÷ (−2)
= = 2−6
So, the slope is 2.
Now, keep this rule in mind: the product of a slope of two perpendicular lines will be -1.
Thus, the slope of the line that is perpendicular to this line is -1/2
