find the radius given the linear speed and rate of rotation v=24.8m/s, 120 rev/mins
Answer:
I got you Fam
Step-by-step explanation:
The radius is 12.4 meters if the linear speed and rate of rotation v=24.8m/s, 120 rev/mins.
What is angular acceleration?It is defined as the rate of change in angular velocity with respect to time. It is also known as rotational acceleration.
It is given that:
The rate of rotation v = 24.8 m/s
The angular velocity w = 120 rev/mins
In rev/second
The angular velocity w = (120/60) rev/second = 2 rev/sec
The formula:
v = rw
Here r is the radius
r = v/w
r = 24.8/2
r = 12.4 meters
Thus, the radius is 12.4 meters if the linear speed and rate of rotation v=24.8m/s, 120 rev/mins.

Remy has $150 to spend on party supplies. She spends $75.50 on decorations and various other supplies. She spent the remaining money to order invitations. If she invited 20 people to her party, how much was the cost to print each invitation?
Answer:
the cost to price of each invitation is $3.725
Step-by-step explanation:
Given that
On party supplies she incurred $150
For decorations and various other supplies she incurred $75.50
The remaining amount i.e.
= $150 - $75.50
= $74.50
This amount would be incurred for the invitations
Now she invited 20 people
SO the cost to price of each invitation is
= $74.50 ÷ 20 people
= $3.725
Hence, the cost to price of each invitation is $3.725

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long. Each president's picture is 6 inches wide. If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?
Answer:
8 pictures
Step-by-step explanation:
Given
[tex]Window = 5\frac{3}{4}ft[/tex]
[tex]Wall = 9.75ft[/tex]
[tex]Pictures = 6\ inches[/tex]
Required
Determine the number of pictures
First, we need to calculate the length of the available space
This is calculated by subtracting the width of the window from the width of the wall.
[tex]Space = Wall - Window[/tex]
[tex]Space = 9.75 - 5\frac{3}{4}[/tex]
Convert fraction to decimal
[tex]Space = 9.75 - 5.75[/tex]
[tex]Space = 4ft[/tex]
Since, the pictures are placed side by side.
This means that, there's no empty space between them.
Number of pictures is:
[tex]Number = \frac{Space}{Pictures}[/tex]
[tex]Number = \frac{4\ ft}{6\ in}[/tex]
Convert feet to inches
[tex]Number = \frac{4 * 12\ in}{6\ in}[/tex]
[tex]Number = \frac{48\ in}{6\ in}[/tex]
[tex]Number = \frac{48}{6}[/tex]
[tex]Number = 8[/tex]
Hence, 8 pictures can fit the wall
Answer:

23. is divisible by 9
Step-by-step explanation:
A number is divisible by 9 if the sum of its digits is divisible by 9. The process of reducing the sum of digits to a single digit is called "casting out nines." It can be a useful process for checking arithmetic of all sorts.
A number is divisible by 3 if the sum of its digits is divisible by 3.

22. 114 is divisible by 3 because 1+1+4 = 6, a number divisible by 3. Everyone will have a spot.
__
24. 2187 has a sum of digits of 2+1+8+7 = 18, which has a sum of digits of 1+8=9. This is divisible by 9, so 2187 is divisible by 9.

What is the value of X in this triangle?
Answer:
x = 3
Step-by-step explanation:
An equilateral ∆ has equal side lengths and all its angles are also equal to each other, which are 60° each.
The ∆ given has equal side lengths. Therefore it is an equilateral ∆ having equal angles, each would measure 60°.
Thus:
(25x - 15) = 60°
Solve for x
25x - 15 = 60
Add 16 to both sides
25x - 15 + 15 = 60 + 15
25x = 75
Divide both sides by 25
25x/25 = 75/25
x = 3
