Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).
Question:
Karina has recently begun kickboxing and purchased training equipment as modeled in the diagram below. The cylindrical base is 15 inches tall with a diameter of 22 inches.
Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).
Answer:
[tex]Section = 4847.3205\ in^3[/tex]
Step-by-step explanation:
Given
[tex]h = 15in[/tex] -- height
[tex]d = 22in[/tex] -- diameter
Required
85% of the volume
First, calculate the radius
[tex]r = \frac{1}{2} * d[/tex]
[tex]r = \frac{1}{2} * 22= 11in[/tex]
The volume (V) is then calculated using:
[tex]V = \pi r^2h[/tex]
[tex]V = 3.142* 11^2 * 15[/tex]
[tex]V = 5702.73\ in^3[/tex]
85% of the volume is:
[tex]Section = 85\% * V[/tex]
[tex]Section = 85\% * 5702.73\ in^3[/tex]
[tex]Section = 4847.3205\ in^3[/tex]
Answer:
The answer above me is correct.

What is the surface area of the regular pyramid below?
I need help please is for tomorrow):
Answer:
Step-by-step explanation:
If a number gets increased by scale factor = k
Then k > 1
If the number gets decreased by a scale factor 'k'
Then 0 < k < 1
Let numbers gets increased by the scale factor = 2,
And decreased by the scale factor = [tex]\frac{1}{2}[/tex]
Numbers Scale up by 2 Scale down by [tex]\frac{1}{2}[/tex]
0.05 0.05 × 2 = 0.1 0.05 × [tex]\frac{1}{2}[/tex] = 0.025
[tex]\frac{1}{2}[/tex] [tex]\frac{1}{2}\times 2 = 1[/tex] [tex]\frac{1}{2}\times \frac{1}{2}=\frac{1}{4}[/tex]
7 7 × 2 = 14 7 × [tex]\frac{1}{2}[/tex] = 3.5
13 13 × 2 = 26 [tex]13\times \frac{1}{2}=6.5[/tex]
25 25 × 2 = 50 [tex]25\times \frac{1}{2}=12.5[/tex]
102 102 × 2 = 204 [tex]102\times \frac{1}{2}=51[/tex]
Henry is mixing concrete.
To make concrete he needs to mix cement, sand and gravel in the ratio 3 : 2 : 7 by weight.
Henry needs to make 180kg of concrete.
He has 46kg of cement, 29kg of sand and 105kg of gravel.
Which ingredient is Henry short of?
9514 1404 393
Answer:
1 kg of sand
Step-by-step explanation:
For 180 kg of concrete using the given ratios, you need ...
(3/12)(180 kg) = 45 kg of cement
(2/12)(180 kg) = 30 kg of sand
(7/12)(180 kg) = 105 kg of gravel
The inventory of 29 kg of sand is 1 kg short of the amount needed.
Henry is short 1 kg of sand.
7=2z+6
Please explain the answer too.
Answer: z = 1/2
Step-by-step explanation: subtract 6 from both sides to get 2z=1 divide both sides by 2, you get z = 1/2 check by inputting 1/2 for z
2(1/2)+6= 7
1/2 of 2 is 1
1+6=7
it checks out :)
Answer: z= 1/2
explanation:
if 7=2z+6, z would be 1/2, because 2 times 1/2=1. then 6+1 s equal to 7

anice has $64 left in her checking account. If she writes a check for $87, what
vill Josie's balance be?
Writing a check takes money out of the bank account. Subtract the amount of the check from the amount in the account:
64 - 87 = -23
They would have -$23 in the account
Tentukan nilai limit x->3 x2-9/x-3
Answer:
6
Step-by-step explanation:
Factor the numerator, difference of squares
[tex]\frac{(x-3)(x+3)}{x-3}[/tex] ( cancel x- 3 on numerator/ denominator )
= x + 3
limit as x → 3 = 3 + 3 = 6
Is 7 to the 8th power times 7 equivalent to 7 to the the third power times 7 to third power equivalent?
Answer:
They are not equivalent.
Step-by-step explanation:
Before we solve the question, we need to know that from the laws of indices:
A^x x A^y = A^(x+y).
7 to the power of 8th power means 7^8
7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.
7 to the power of 3rd power means 7^3
7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.
Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.

What type of correlation exists between the temperature and the number of fruit bars sold? What is the real-world meaning of the slope of the line of best fit for the given scenario? There are approximately more fruit bars sold for every degree(s) the temperature rises
Answer:
There's no figure, but okay! The type of correlation that exists between the temperature and the number of fruit bars sold is a positive correlation.
The real-world meaning of the slope of the line of best fit for the given scenario is that: As the temperature increases, so too does the number of fruit bars sold.
I hope that helps you!! ^-^
Answer:

Find the measure of angle h
Answer:
62 degrees
Step-by-step explanation:
Since we know 3 sides of the triangle, we can use law of cosines.
[tex] {gk}^{2} = {gh}^{2} + {kh}^{2} - 2(gh)(kh) \times \cos(h) [/tex]
[tex] {8}^{2} = {17}^{2} + {15}^{2} - 2(17(15) \times \cos(h) [/tex]
[tex]64 = 289 + 225 - 510 \times \cos(h) [/tex]
[tex]64 = 314 - 510 \times \cos(h) [/tex]
[tex] - 250 = - 510 \times \cos(h) [/tex]
[tex] \frac{250}{510} = \cos(h) [/tex]
[tex] \frac{25}{53} = \cos(h) [/tex]
Take the arcos or cosine inverse
[tex] \cos {}^{ - 1} = \frac{25}{53} [/tex]
Which is about 62 degrees.
Mary had $156.00 and spent 1/6 of it for a coat. She then bought a skirt with 1/4 the money she had left. How much money did she have left after buying her coat and skirt? Group of answer choices
Answer: $ 97.5
Step-by-step explanation:
156 * 1/6 = 26
156-26=130
130 * 1/4- 32.5
130-32.4= 97.5
The function f(x) = 34,000(1.05)* can be used to
determine Noah's cost of living in Houston over time.
What does the 1.05 represent?
A The cost of living will increase by approximately 1% each year
B The cost of living will decrease by approximately 1% each year
C The cost of living will increase by approximately 5% each year
D The cost of living will decrease by approximately 5% each year
9514 1404 393
Answer:
C The cost of living will increase by approximately 5% each year
Step-by-step explanation:
If we assume your function is ...
[tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]
Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.
Noah's cost of living is increasing about 5% per year.

A bag contains 20 pink candies, 8 red candies, and 12
green candies. Without looking, Sarah pulls out a piece of
candy. Which color of candy is least likely to be pulled
out?
Answer:
red candies
Step-by-step explanation:
Statistically:
• 2/3 (20/30) times the candy will be pink
• 4/15 (8/30) times the candy will be red
• 2/5 (12/30) times the candy will be green
[tex] \frac{20}{30} > \frac{12}{30} > \frac{8}{30} [/tex]
Red candies will be least likely to be pulled.
Which exponential function matches the table?
Answer:
B: f(x) = 27[tex](\frac{1}{3})^{x}[/tex]
Step-by-step explanation:
If you substitute 0 and 1 into each given exponential function. The first, second and fourth value with 0 substituted will give 27 as such, so we can eliminate the third exponential function. But, if you substitute 1 into all of the remaining possible exponential functions, the only function that will give you 9, when x = 1 is substituted, is B: f(x) = 27[tex](\frac{1}{3})^{x}[/tex].
I hope this helps you!! ^-^
A study showed that the ratio of the number of people who get their news from social media to the number of people who their news from other sources is 3 to 7. Based on the ratio, how many people in a town of 900 people get their news from social media?
Answer: 270 people
Step-by-step explanation:
The ratio of the number of people who get their news from social media to the number of people who their news from other sources is 3 to 7.
This shows that the number of people who get their news from social media is 3 out of 10 i.e (3+7).
Therefore, the number of people in a town of 900 people that get their news from social media will be:
= 3/10 × 900
= 270 people.
