Answer: The volume of the cylinder is 640π cm³
Step-by-step explanation:
The formula of the surface area of a cylinder is SA = 2πrh + 2πr², where r is the radius of its base and h is its height
The formula of the volume of a cylinder is V = πr²h
Let us use the formula of the surface area to find the height of the cylinder, then use the formula of the volume to find its volume
∵ The surface area of a cylinder is 288π cm²
∵ Its radius is 8 cm
∵ SA = 2πrh + 2πr²
- Substitute the SA by 288π and r by 8 in the formula
∴ 288π = 2π(8)h + 2π(8)²
∴ 288π = 16πh + 128π
- Subtract 128π from both sides
∴ 160π = 16πh
- Divide both sides by 16π
∴ 10 = h
∴ The height of the cylinder is 10 cm
Now let us find the volume of the cylinder
∵ V = πr²h
- Substitute r by 8 and h by 10
∴ V = π(8)²(10)
∴ V = π(64)(10)
∴ V = 640π
The volume of the cylinder is 640π cm³
Expand and simply (x + 3) (x + 5)
-4(3/2x - 1/2) = -15
Answer:
2.8333333333333333333
Step-by-step explanation:
I have high iq
-4(3/2x - 1/2) = -15
Distribute -4
-6x + 2 = -15
Subtract 2 from both sides
-6x = -17
Divide 6 from both sides
x = 2.83333333333333333

I’ll mark you as the brainliest for the correct answer thanks
Answer:

Step-by-step explanation:
If f(x) is a linear function, f(- 3) = - 3 , and f(5) = 4 , find an equation for f(x)
[tex]f(x)=mx+b[/tex]
[tex]f(-3)=-3[/tex] meaning that (-3,-3)
[tex]f(5)=4[/tex] meaning that (5,4)
(1 ) Find slope.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{4+3}{5+3}\\m=\frac{7}{8}[/tex]
The slope is 7/8
(2) Substitute any ordered pairs in the equation.
I'll use (5,4)
[tex]f(x) = \frac{7}{8}x+b\\4=\frac{7}{8}(5)+b\\4=\frac{35}{8}+b\\32=35+8b\\32-35=8b\\-3=8b\\-\frac{3}{8}=b\\b=-\frac{3}{8}[/tex]
Therefore the equation for f(x) is [tex]f(x)=\frac{7}{8}x-\frac{3}{8}[/tex]

Simplify. Round to the nearest tenth. 5.4% of 65 *
Answer:
3.5
Step-by-step explanation:
1. 5.4% X 65
2. 5.4/100 x 65
3. 0.054 x 65
Answer =3.5
3.5 is approximately 5.4% of 65 rounding to the nearest tenth
To calculate 5.4 % of 65 and simplify the result to the nearest tenth, we can multiply 65 by 0.054.
65 * 0.054 = 3.51
Rounding this value to the nearest tenth, we find that 5.4 % of 65 is approximately 3.5.
Therefore, after rounding to the nearest tenth, 5.4 % of 65 simplifies to 3.5. This means that 3.5 is approximately 5.4 % of 65 rounding to the nearest tenth. It represents the amount you would get if you took 5.4 % of 65, rounded to one decimal place.

Shen’s mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14 per pound, and a box of cereal for $3.46. Shen used front-end estimation to determine whether he had enough money for the groceries. How much did he estimate the total cost would be?
He estimated that he had about $7 worth of groceries.
He estimated that he had about $9 worth of groceries.
He estimated that he had about $10.30 worth of groceries.
He estimated that he had about $10.40 worth of groceries.
Answer:
He estimated there were about $10.40 worth of groceries
Step-by-step explanation:

10.45
So 10.45 is closest to 10.40 and you have to remeber that this is just an estimate so it will be less because we rounded the answer up.
Hope this helps
Answer:
$9 its be heres my work
Step-by-step explanation:
Gallon of milk: $3.49
3lbs oranges: $1.14(3) = $3.42
Box of cereal: $3.46
Front end estimation is taking the number in front and the rest of the numbers coming after it will be zeroes.
Using front end estimation:
$3.49 => $3.00
$3.42 => $3.00
$3.46 => $3.00
Add all these up; Shen estimated the total cost of the groceries would be $9.00.
