The slant height of a cone with lateral surface are of 19.2π inches squared and radius of 2.4 inches is 8 inches.
Lateral surface area of a coneThe formula for the lateral surface area of a cone is described as follows:
Lateral area = πrl
where
r = base radiusl = slant heightTherefore,
Lateral area = 19.2π inches²
r = 2.4 inches
Lateral area = π × 2.4 × l
19.2π = 2.4πl
divide both sides by 2.4π
l = 19.2π / 2.4π
l = 8 inches

Answer:
Y = 40
Step-by-step explanation:
First, find the slope-intercept of the table
Slope-intercept form: y = mx + b
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(3, 1) and (6,2)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}[/tex]
[tex]y=mx+b[/tex]
[tex]y=\frac{1}{3}x+b[/tex]
Find b using (6,2):
[tex]y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b[/tex]
[tex]y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x[/tex]
[tex]y=\frac{1}{3}x[/tex]
What will be the value of Y when X = 120?
Substitute 120 for x into [tex]y=\frac{1}{3}x[/tex]
[tex]y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40[/tex]
(120, 40)
Therefore, when X = 120, Y = 40

Answer:
y=2 cos (π/4x-π/4)
Step-by-step explanation:
Given
A cosine function has an amplitude of 2, a midline of 5 and a period of 8.
To find:
A cosine function.
Explanation:
Let the function be,
[tex]y=Acos(ws+p)[/tex]
Since amplitude is 2.
Then,
[tex]A=2[/tex]
Also, since the period is 8.
Then,
[tex]w=\frac{2\pi }{8}[/tex]
[tex]w=\frac{\pi }{4}[/tex]
And, since midline is 5.
Hence, the cosine function is,

Step-by-step explanation:
Convert the fraction to a decimal by dividing the numerator by the denominator.
You buy a car from your neighbor at a price of $9,000. You pay $500 down and pay 9.5% on the balance. If you make monthly payments of $200, how many months (to the nearest hundredth of a month) will it take to pay off the loan? (Hint: Solve for N.)
If the monthly payments mad s $200, the number of months it would take to pay off the loan is 46.54 months.
How many months would it take to pay off the loan?The first step is to determine the total value of the loan.
Total value of the loan = (1 + interest) x amount of the loan
Amount of the loan = 9000 - 500 = $8,500
Total value of the loan = (1.095) x $8500 = $9307.50
Number of months it would take to pay off the loan = total value of the loan / monthly payments
$9307.50 / 200 = 46.54 months

Answer:
%26
Step-by-step explanation:
We can set up a proportion to find out what percentage of the gumballs are red:
[tex]\frac{525252}{232323+525252+343434+616161+303030} =\frac{x}{100}[/tex]
[tex]\frac{525252}{2020200} =\frac{x}{100}[/tex]

[tex]\frac{(525252)(100)}{2020200} =x[/tex]
[tex]26=x[/tex]
Since we set up x as a fraction of 100 when writing the proportion we can say that the percentage of red gumballs is %26.

Length ×Breadth9.5(7.5)71.25cm²The area of the drawing is 71.25 square cm.
What is Area of Rectangle?The area of Rectangle is length times of width.
The actual dimensions of the rectangle are 95 m by 75 m.
The drawing is made to a scale of 1 cm to 10 m, which means that each centimeter on the drawing represents 10 meters.
Let us find the area of the drawing
First calculate the area of the rectangle in real life, and then scale it down using the ratio of 1 cm to 10 m.
The area of the rectangle in real life is:
95 m × 75 m = 7125 square meters
To scale this down to the drawing, we need to divide both dimensions by 10.
The area of the drawing is
(95 m / 10) × (75 m / 10)
= 9.5 cm × 7.5 cm
= 71.25 square cm
Therefore, the area of the drawing is 71.25 square cm.

Answer:
30 degrees
Step-by-step explanation:
The angles of each side of a hexagon is 120 degrees.
The sum of interior angles in a shape is (n-2) * 180.
So,
(6-2) * 180 = 4 * 180 = 720 degrees
This is the total degrees of the hexagon.
Dividing the total degrees by 6 angles gives us 120 degrees for each angle.
Angle AEF = angle FED - angle AED.
Angle FED = 120 degrees
Angle AED = 90 degrees
120 - 90 = 30 degrees
