Answer:
803.84 Cm Squared
Step-by-step explanation:
A= π r2
A = 3.14 times 16 squared
A = 803.84
6x – 64 = 2x - 44
solve for x
Answer: x= 5
Step-by-step explanation: subtract 2x from both sides eliminating 2x.
4x-64=-44 add 64 to both sides eliminating -64
4x=20 divide by 4
20/4 = 5
4x/4 = x
x= 5
Hope this helps :)
solve the equation

Which graph shows the function
4y - x= 0?
Answer:
y=x/4
Step-by-step explanation:
add x to the other side of your equation so: 4y = x
now divide both sides by 4 so your y is isolated: y=x/4

Answer: C = 9
Step-by-step explanation:
Answer:
c=10.6
Step-by-step explanation:
In this we need to find c and we know that this is a right triangle
Therefore, I can use the Pythagorean Theorem which is a^2 + b^2 = c^2.
using this we then plug in a=8 and b=7 while c is the hypotenuse.
Now the equation is now 8^2 + 7^2 = c^2. We then solve for c.
8^2 + 7^2 = c^2
64 + 49 = c^2
113 = c^2
√113 = c
c = 10.630145...
Since the questions asks to round to the nearest tenth then the answer would be 10.6

11. Amelia walked for 12 minutes then ran for
32 minutes. What is the ratio for the time
she spent walking to the time she spent
running?
Answer:
9 Miles to be specific 8.95
Step-by-step explanation:
3 miles = 4.83 km
4.83 km = 4830 m
60 seconds X 45 =2700 Seconds
4830 divided by 2700 = 1.78 m/s
you want to know the distance so its speed X time
135 minutes X 60 seconds = 8100 secs
1.78 m/s X 8100 =14418 meters
14418 = 14.418 km
14.418 km = 9 miles
P.S. There is a shorter version but i think this is simpler for me and I use metric units.
Andros has an oil fired heating system. In 30 days period he used a full tank of oil at a constant rate per day . At a different time of the year the amount of oil andros uses per day is 1/3 of the rate used in 30 days period . How many days should a full tank of oil last at this new rate
Answer:
90 days
Step-by-step explanation:
Let the rate per day for the 30 days period be x
Given that the rate drops to 1/3 of the rate used in 30 days period, it means that the new rate
= 1/3 x
If at a rate of x, the full tank runs for 30 days
at a rate of 1/3 x, the full tank would run for
= x/ (1/3 x) * 30 days
= 3 * 30 days
= 90 days
At the new rate, the full tank of oil will last for 90 days
I need help ASAP! And work needs to be shown!
Answer:
32 x p/100 = 40
(Solve for P)
Multiply by 100 on both sides
32x = 4,000
Divide by 32 to get:
X = 125%
(reason why you multiply by 100 is because opposite of division is multiplication and we multiply the number "100" because we always multiply the denominator to both sides when having a fraction so you can solve for p or whatever. And that means p/100 x 100 it means p because since p is not a known value we consider 1/100 x 100 = 1, a variable by itself means 1 so you could just put p by itself next to the number its multiplied by which is 32 so it would be 32p because your multiplying both and the opposite of that would be dividing by 32 on both sides because you are getting rid of the 32 so therefore you will be left with: X = 125)

Investment firm claims that the mean increase in price per share companies invest in is $1.95 per share every year and national sample of 100 company shows that the mean increase in price per share is $1.82 per year the standard deviation of share price is nationally is $.30 what is the margin of error
Answer:
The Margin of Error in percentage is 5.88%
Step-by-step explanation:
The values of the factors in the question are;
The mean increase in price per share, = $1.95
The number of companies in the sample, n = 100
The mean increase in price per share, [tex]\overline x[/tex] = $1.82
The standard deviation of the population, σ = $0.30
The margin of error, MOE, is given by the following formula;
[tex]Margin \ of \ Error= z \times \dfrac{\sigma}{\sqrt{n} }[/tex]
Where;
z = z-score, critical value = 1.96 at 95%
σ = The standard deviation of the population = $0.30
n = The sample size = 100
Therefore, we have;
[tex]Margin \ of \ Error= 1.96 \times \dfrac{0.3}{\sqrt{100} } = 0.0588[/tex]
The Margin of Error in percentage = 0.0588 × 100 = 58.8%
The Margin of Error in percentage = 5.88%

At a middle school, 18% of all seventh grades are teacher's aides. 64 seventh graders are teacher's aides, how many seventh graders are at the middle school? (Round to the nearest whole)
Answer:
356 Seventh Graders
Step-by-step explanation:
All I did was find out what number 64 was 18% of, and that gave me the answer. I took 64 and put it over 18%, and set it across from X over 100%. I did the cross multiplication, and got 355.56, but rounded it to get 356. So there are 356 total seventh graders. Hope this is helpful...have a great day! :))
