A company rents water tanks shaped like cylinders. Each tank has a diameter of 8 feet and a height of 3 feet. The cost is $5 per cubic foot. How much does it cost to rent one water tank?
Answer:
$754.05
Step-by-step explanation:
We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.
The volume of a cylinder is:
[tex]V = \pi r^2h[/tex]
where r = radius
h = height
Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.
The volume of the tank is therefore:
[tex]V = \pi * 4^2 * 3 = 150.81 ft^3[/tex]
The cost of renting is $5 per cubic foot.
Therefore, the cost of renting a tank is:
150.81 * 5 = $754.05
It costs $754.05 to rent a tank.
A sine function can be used to model light waves. Green light has a wave length, or period of about 520 nm. Which equation best models green light?
A.) y=sin 260/pi theta
B.) y= sin pi/520 theta
C.) y= sin 520/pi theta
D.) y= sin pi/260 theta
Please help
Answer:
[tex] y = A sin (kx \pm wt)[/tex]
Where k represent the number of wave [tex]k =\frac{2\pi}{\lambda}[/tex] and [tex] w =\frac{2\pi}{T}[/tex] represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
[tex] w = \frac{2\pi}{520}= \frac{pi}{260}[/tex]
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
Step-by-step explanation:
Since the sine function can be used to model light waves we can use the following general expression:
[tex] y = A sin (kx \pm wt)[/tex]
Where k represent the number of wave [tex]k =\frac{2\pi}{\lambda}[/tex] and [tex] w =\frac{2\pi}{T}[/tex] represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
[tex] w = \frac{2\pi}{520}= \frac{pi}{260}[/tex]
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.

Rosanne is training for the Austin marathon, so she plans to run 10 miles in her neighborhood this weekend. It usually takes her an hour to run 6 miles. If she generally drinks 0.5 cups of water every 1 3 of an hour, how many cups of water will she drink on her run?
Answer:2.5 cups
Step-by-step explanation:
Given
Rosanne runs 6 miles in an hour
If she drinks 0.5 cups of water every [tex]\frac{1}{3}[/tex] of an hour
So in 1 hour Rosanne drinks 1.5 cups
So, for 6 miles Rosanne drinks 1.5 cups
i.e. For [tex]1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}[/tex]
for [tex]10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}[/tex]

A cube fish tank has a side length of 12 inches. What is the surface area of the fish tank, including the base and lid? Answer without units
Answer:
864
Step-by-step explanation:
Because the tank is a cube, all 6 faces have dimensions of 12 by 12. Therefore, the surface area is 6 * (12 * 12) = 864 (in²)
Find the approximate perimeter of polygon CODIFYCODIFYC, O, D, I, F, Y plotted below.
Round your final answer to the nearest hundredth.
please helppp
Answer:
49.81
Step-by-step explanation:
the formula I used is distance=[tex]\sqrt{(x_{2}-x_{1})+(y_{2}-y_{1})}[/tex]
Lets say we are finding the distance from c to y
c=(-6,9)
y=(5,9)
cy=[tex]\sqrt{(5-(-6))^{2}+(9-9)^2 }[/tex]
cy=[tex]\sqrt{(11)^2+(0)^2}[/tex]
cy=[tex]\sqrt{121+0}[/tex]
cy=[tex]\sqrt{121}[/tex]
cy=11
And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.
After solving the distance of all I got
yi=16.55294536
id=1
do=9.219544457
oc=12.04159458
After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.
Thank you and I hope that is helpful.

Renu wants to put a border of lace around a rectangular table cover 4 m long and 2 m wide..
Find the length of the lace required for the table cover..
Answer:12m
Step-by-step explanation:
The length of the lace required will be the same as that obtained by calculating the perimeter of that table, so p= (L+W)×2
Hence, P=(4m+2m)×2
P= 12m
A figure is dilated by a scale factor of 3. If the origin is the center of dilation, what is the image of a vertex located at (3, 4)?
Answer:
(9,12).
Step-by-step explanation:
If a figure dilated by a scale factor of k and origin is the center of dilation, then the relation between point and its image is defined as
[tex]P(x,y)=P'(kx,ky)[/tex]
It is given that a figure is dilated by a scale factor of 3 and origin is the center of dilation. So,
[tex]P(x,y)=P'(3x,3y)[/tex]
We need to find the image of a vertex located at (3, 4). So, substitute x=3 and y=4 in the above rule of dilation.
[tex]P(3,4)=P'(3(3),3(4))[/tex]
[tex]P(3,4)=P'(9,12)[/tex]
Therefore, the image of a vertex located at (3, 4) is (9,12).
Answer: 9,12

Jen and Holly are on the Athletic council and want to put a blow up version on the school mascot in the parking lot. They need to tie it down.
Jen’s rope is 7.8 m long and makes an angle of 360 with the ground. Holly’s rope is 5.9 m long. The wind is really strong so they will secure both ropes to the left of the mascot. How far to the nearest tenth of a metre, is Jen from Holly?
Answer:
2.6 m
Step-by-step explanation:
In the attached diagram
Consider Triangle ABC
[tex]\sin36^\circ =\dfrac{|BC|}{7.8} \\|BC|=7.8*\sin36^\circ\\|BC|=4.5847$ m[/tex]
Our goal is to determine the distance of Jen (at point A) to Holly (at Point D).
In Triangle ABC
[tex]\cos 36^\circ =\dfrac{|AC|}{7.8} \\|AC|=7.8*\cos36^\circ\\|AC|=6.3103$ m[/tex]
In Triangle BDC
Applying Pythagoras Theorem
[tex]|BD|^2=|BC|^2+|CD|^2\\5.9^2=4.5847^2+|CD|^2\\|CD|^2=5.9^2-4.5847^2\\|CD|^2=13.7905\\|CD|=\sqrt{13.7905}=3.7136$ m[/tex]
Now, |AC|=|AD|+|DC|
6.3103=|AD|+3.7136
|AD|=6.3103-3.7136
|AD|=2.5967
|AD|=2.6m (correct to the nearest tenth of a metre)
The distance of Jen from Holly is 2.6m.

The number i can be raised to whole number powers.
Look at the first four powers of i shown, and then use the drop-down menus to evaluate the expressions below.
Answer:
[tex]i^{8}=1[/tex] and [tex]i^{34}=-1[/tex] will be the answer.
Step-by-step explanation:
Since i = [tex]\sqrt{(-1)}[/tex]
i² = (-1)
[tex]i^{3}=-i[/tex]
[tex]i^{4}=(-1)^{2}[/tex] = 1
[tex]i^{8}=1^{2}[/tex] = 1
[tex](i^{8})^{2}=1[/tex]
[tex]i^{34}=[i^{17}]^2[/tex]
= [tex](i^{8}\times i^{8}\times i)^{2}[/tex]
= [1 × 1 × √(-1)]²
= 1² × 1² × [√(-1)]²
= (-1)
Therefore, [tex]i^{8}=1[/tex] and [tex]i^{34}=-1[/tex] will be the answer.

4/8 +6/8 I just verfying the other person's. ok
Step-by-step explanation:
I did it on a calculator ;b
PLEASE MARK FallOutChild brainliest!!
Answer:
4/8 + 6/8 = 10/8 or 1 2/8, 1 1/4
Step-by-step explanation:
When it asks for like units, it's asking for the same denominator value. You can not add fractions together when they do not have a common denominator
if you multiply the denominator and numerator in 2/4 by 2, you get 4/8
Result of 4/8 + 6/8 gives you an improper fraction of 10/8

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking an even number and then picking an even number?
Simplify your answer and write it as a fraction or whole number.
Answer:
2/5
Step-by-step explanation:
Answer:
1/6
Step-by-step explanation:
Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!
