Answer:
678.24
Step-by-step explanation:
First, we have to find the area of 1 cylinder(pi x r^2 x h), which i got as 226.08 then we multiply by 3 because there are 3 cylinders. 226.08 x 3 = 678.24
Answer: Hope this helps you!
678.24Step-by-step explanation:
First, I started off with the equation of the area of a cylinder
Area = π * radius^2 * height
Now I will go on and substitute
Area = 3.14 * 3^2 * 8
And now I will start solving
Area = 3.14 * 3^2 * 8
(3^2 = 3*3 = 9)
Area = 3.14 * 9 * 8
(9*8 = 72)
Area = 3.14 * 72
Area = 226.08
The area of 1 cylinder is 226.08, however we need to find the area of the whole composite figure which is made up of 3 cylinders.
226.08 * 3 = 678.24
The answer is 678.24(Make me brainliest!)Someone help w pre-algebra, smth about proportional data
Answer:
The answer is no because for 1 hour he gets 20 dollars and for 2 hours he gets 30$ (which is less for working 2 hours). So, if you multiply 2 hours with 20 dollars, you should get 40, not 30. So therefore, it is not proportional. And same for 3 hours: multiply 3 with 20 to get 60, not 50.

equation: -7x+6= x squared-7x
Answer:
x = √6 or - √6
Step-by-step explanation:
equation: -7x + 6 = x² - 7x
switch sides:
x² - 7x = -7x + 6
Add 7x to both sides,
x² - 7x + 7x = -7x + 7x + 6
x² = 6
For x² = f(a) the solution are x = √f(a), -√f(a)
x = √6 , x = - √6
Answer:
-7x + 6 = x² - 7x
-7x + 7x +6 - x² = 0
0 + 6 - x² = 0
-x² + 6 = 0
-x² = (-6)
x² = 6
x = ±√6
x =√6 or x = -√6

how do i turn a fraction into its simplest form?
Answer:
You divide both the numerator and the denominator by the same number until they can't be reduced any further.
Answer:
Make sure to divide the upper number and the lower number (in position) to a number which can't be futher divided. It will be of numbers which are really small numbers. like 4/2 will be divided by 2 to get the simplified answer of 1/2

- Please help, thank you
Split the integrand into partial fractions.
[tex]\dfrac{9x+2}{x^2+x-6} = \dfrac{9x+2}{(x-2)(x+3)} = \dfrac a{x-2} + \dfrac b{x+3}[/tex]
[tex]\implies 9x+2 = a(x+3) + b(x-2) = (a+b)x + (3a-2b)[/tex]
[tex]\implies \begin{cases}a+b=9 \\ 3a-2b=2\end{cases} \implies a=4,b=5[/tex]
Then we have
[tex]\displaystyle \int \frac{9x+2}{x^2+x-6} \, dx = 4 \int \frac{dx}{x-2} + 5 \int \frac{dx}{x+3} \\\\ = \boxed{4\ln|x-2| + 5\ln|x+3| + C}[/tex]
which follows from the result
[tex]\displaystyle \int \frac{dx}x = \ln|x|+C[/tex]

This program simplifies our complex monetary system by familiarizing users with common combinations of coins and bills that are equivalent in value. Starting with five pennies equal one nickel, the program works up to equivalents for a twenty dollar bill.
Answer:
$1.05
Step-by-step explanation:
1 dime = 10 cents so 7 dimes = 70 cents
1 quarter = 25 cents
Therefore 10 cents + 7 dimes + 1 quarter = 10 + 70 + 25 = 105 cents = $1.05
John works as a part time waiter in a restaurant. He gets a monthly salary of ₹4,410.Calculate John’s daily, weekly and annual salary.(Take 1 month= 30 days)
1 month is aprox. 30 days, so
To find john's daily salary:
For a month, the salary is 4,410 rupees, so for a day how much?
days salary
30 4,410 (This is how I learnt to solve these kind of problems)
1 ?
Then you crisscross the equation which becomes
4,410/30=147 rupees
To find weekly salary:
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?
You multiply the salary for one day and the number of days: 147×7=1,029 rupees
To find salary for a year (annual):
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 365 days (1 year) how much?
You multiply the salary for one day and the number of days: 147×365=53,655 rupees
Hope it helps!

Answer:
one paperback = 0.6 pounds
one textbook = 3.6 pounds
Explanation:
Let the mass of one paperback be 'p' and one textbook be 't'.
Equation one:
sum of mass = total mass in box
20p + 9t = 44.4Equation two:
20p + 5p + 9t + 1t = 5125p + 10t = 51make 't' subject
10t = 51 - 25pt = 5.1 - 2.5pInsert this into equation one:
20p + 9(5.1 - 2.5p) = 44.4
20p + 45.9 - 22.5p = 44.4
20p - 22.5p = 44.4 - 45.9
-2.5p = -1.5
p = 0.6
The weight of 1 paperback is 0.6 pounds.
The weight of 1 textbook:
t = 5.1 - 2.5p
t = 5.1 - 2.5(0.6)
t = 3.6
The weight of 1 textbook is 3.6 pounds.

Answer:

Step-by-step explanation:
3 + -4 - 7
3 - 4 - 7
-1 - 7
-8
Answer: -8
Step-by-step explanation:
3+(-4)-7
Whenever you have a +(- something), it ALWAYS becomes a -
So 3+(-4)= 3-4
Now we have:
3-4-7
PEMDAS states that you must do the subtraction from left to right. So you start with the 3-4.
3-4-7
-1-7
-8
Whenever you have a negative number minus a number , the result will always be negative.
Hence, thats why the answer is -8

Answer:
30%
Step-by-step explanation:
To express percentage as a fraction, the denominator must be 100.
Given ,
[tex]\frac{18/60}{60/60}\\= \frac{0.3}{1} \\= 0.3 * 100\\= 30%[/tex]
Answer:
1) Percent of skateboards that are longboards is 18÷60 or 30%
2) Number needed for equivalent ratio is 30 longboards
Step-by-step explanation:
1) Percentage= part divided by whole
18÷60 = 0.3
0.3 = 30%
2) Create a proportion, let x = # longboards needed for a equivalent ratio
(18÷60)=(x÷100)
x=30

5. Steph took out a compound interest loan that charges 2.5% interest annually. If her original loan amount was for $60,000 and she is paying off the loan over 2 years, how much will she pay altogether? What is the interest?
Answer:
1. 96%
2. $6000
3. 176
4. 20%
Step-by-step explanation:
1. 1/5 of 80% is 16%. 80+16=96
2. 25% of 8000 is 2000. 8000-2000= 6000.
3. 10% increase of 200 is 20. 20+200=220. 20 percent of 220 is 44. 220-44=176
4. if you increase the original salary by 20%, then decreasing it by 20% of the new salary will give you the old salary.
