Answer:
We conclude that the estimated volume of a cylinder is 288 in.³
Step-by-step explanation:
Given
r = 3.75 inchesh = 6.21 inchesThe formula to determine the volume of a cyliner is:
[tex]V=\pi r^2h[/tex]
substituting the values r = 3.75 inches, h = 6.21 inches, and π = 3.14 in the formula to calculate the volume of a cylinder.
[tex]V=\pi r^2h[/tex]
[tex]V=\left(3.14\right)\left(3.75\right)^2\times 6.21[/tex]
[tex]V=274[/tex] in.³
Therefore, from the given options, we conclude that the estimated volume of a cylinder is 288 in.³
this is the formula which I am asking you all

Answer: 39
Step-by-step explanation: To find the answer or result of 3 + 3 to the second power + 3 to the third power, you’ll have to find the whole number value of the two integer numbers being 3 to the second power and 3 to the third power. To do this, multiply (3 x 3) and (3 x 3 x 3). You should get 9 and 27. Lastly, you‘ll have to add 3 + 9 + 27, to give you the final answer or result of 39.

Last week, Lindsay earned $10 per hour plus a $60 bonus for good job performance. She spends StartFraction 1 Over 15 EndFractionof her paycheck on dinner with friends. If she had not earned the bonus, the amount she spent on dinner would have been StartFraction 1 Over 10 EndFraction of her paycheck. Which equation can be used to find h, the number of hours Lindsay worked last week?
Answer:
Let
y--------> cost of the dinner with friends
h--------> the number of hours Lindsay worked last week
we know that
y =\frac{1}{15} *( 10h+60)y=
15
1
∗(10h+60) ------> equation 11
y =\frac{1}{10} *( 10h)y=
10
1
∗(10h) ------> equation 22
equate equation 11 and equation 22
\begin{gathered} \frac{1}{15} *( 10h+60)=\frac{1}{10} *( 10h)\\\\ Multiply\ by\ 150\ both\ sides\\\\ 10*(10h+60)=15*10h\\\\ 100h+600=150h\\\\150h-100h=600\\\\ h=\frac{600}{50} \end{gathered}
15
1
∗(10h+60)=
10
1
∗(10h)
Multiply by 150 both sides
10∗(10h+60)=15∗10h
100h+600=150h
150h−100h=600
h=
50
600
h= 12\ hoursh=12 hours
therefore
the answer is
Lindsay worked 12\ hours12 hours last week
The equation that can be used to find the number of hours is
\frac{1}{15} *( 10h+60)=\frac{1}{10} *( 10h)

∗(10h+60)=

Lindsay worked for about 120 hours last week.
What is an equation?An equation is used to show the relationship between two or more variables and numbers.
Let h represent the number of hours Lindsay worked last week, hence:
(1/15)(10h + 600) = (1/10)(10h)
40h + 2400 = 60h
h = 120 hours
Lindsay worked for about 120 hours last week.

Answer: 2521.91 ft^3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using the cylinder volume formula, V = (pi)r^2h
Since the radius and the height have already been given, no further calculations are necessary.
V= (pi)(6.5)^2(19)
V=(3.14)(42.25)(19)

Write an equation in point-slope form of the line that passes through the two given points. Use the first point to write the equation (-1, -5) and (3, 2)
Answer:
The equation in point-slope form of the line is:
[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]
Step-by-step explanation:
Given the points
(-1, -5) (3, 2)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)[/tex]
[tex]m=\frac{2-\left(-5\right)}{3-\left(-1\right)}[/tex]
[tex]m=\frac{7}{4}[/tex]
As the point-slope form is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope.
substituting the values m=7/4 and the first point (-1, -5)
[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]
Therefore, the equation in point-slope form of the line is:
[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

a rectangle has a length 8 cm the rectangle has area 20cm^2 the length of the rectangle is increased by 2 cm the area of the rectangle is increased by 4 cm^2 noh says the width of the rectangle decreased less than 5% is noah correct
9514 1404 393
Answer:
yes
Step-by-step explanation:
The width of the rectangle is given by ...
W = A/L
W = (20 cm²)/(8 cm) = 2.5 cm
__
The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...
W = (24 cm²)/(10 cm) = 2.4 cm
The percentage change in size is ...
((2.4 cm)/(2.5 cm) -1) × 100% = -4%
The width of the rectangle decreased less than 5%. Noah is correct.

The rule of thumb in filmmaking is that you must shoot at least 3 minutes of film for every minute in a movies “final cut”. A 30 minute roll of film cost $250. How much will film cost to make a 90 minute movie?
I can't figure out the process of solving it!!!
P.S: It needs to be set up as an inequality
PLS HELPP
Answer: $750
Step-by-step explanation:
We can solve this using direct proportion.
Let the number of minutes used be x
Let the cost be y
For direct proportion,y = kx
where, y = 250, x = 30
y = kx
250 = 30k
k = 250/30
k = 8.33
The cost to make a 90 minute movie will be:
y = kx
where,
y = unknown
k = 8.33
x = 90
y = 90 × 8.33
y = $750
The cost to make a 90 minute movie is $750.
