Answer:
6042915 balls.
Step-by-step explanation:
Volume of a ping pong ball is;
V = (4/3)πr³
diameter of ping pong ball is given 4cm = 0.04 m
Radius; r = 0.04/2 = 0.02 m
V = (4/3)π(0.02³)
V = 0.00003351032 m³
Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.
Volume; V = 9 × 7.5 × 3 = 202.5 m³
Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151
Approximately 6042915 balls.

or, 5(2x-4)+8x= 5
or, 10x- 20+8x=5
or, 10x-8x= 20+5
or, 2x= 25
or,x= 25/2
:.x= 25/2
Step-by-step explanation:
first we have to make denominator then we can criss cross multiply. we can make in same point .if there is plus we can subtract and if there is front minus if we take it back it must be plus. then we can put same point then we can divide

A) nine and twenty two fortieths
B) nine and three twenty eighths
C) ten and twenty two fortieths
D) ten and eleven thirteenths
( Here is an image if needed):
Answer:
C
Step-by-step explanation
Answer:
C.)
Step-by-step explanation:
First, let's make it so that 6/8 and 4/5 have the same denominator.
Find the LCM: 40
8 ÷ 40 = 5
5 ÷ 40 = 8
Now that we have this info, let's convert the numerator to match the denominator.
4/5:
4 × 8 = 32
So... 4/5 = 32/40
6/8:
6 × 5 = 30
So... 6/8 = 30/40
Now let's add:
30/40 + 32/40
30 + 32 = 62
Therefore: 62/40
Now let's add those whole numbers: 5 + 4 = 9
Our answer: 9 62/40
Let's simplify: 10 22/40
Therefore, C is the correct answer.
Mr. Lyons is laying tile for the rectangular floor of a hotel lobby.
The floor will be 38 tiles wide and 112 tiles long. He has a total of 4,400 tiles.
Which explains whether or not he has enough tiles for the entire floor?
Answer:
yes
Step-by-step explanation:
you find the area by multiplying 38 X 112= 4,256
4,400 - 4,256= 144 left over

Answer:
(3 * 100,000) + (0 * 10,000) + (4 * 1000) + (0 * 100) + (5 * 10) + (6 * 1)
Step-by-step explanation:
We want to represent the value of this number using expanded notation
Mathematically, that will be;
(3 * 100,000) + (0 * 10,000) + (4 * 1000) + (0 * 100) + (5 * 10) + (6 * 1)
= 300,000 + 0 + 4000 + 0 + 50 + 6

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
14
10
Answer:
Submit Answer
Answer:
The area of given figure is: 179.3
Step-by-step explanation:
The figure consists of a rectangle and a semi-circle
The length of rectangle is 14 and width is 10.
The width of rectangle is also the diameter of the semi-circle.
So,
d = 10
[tex]r = \frac{d}{2} = \frac{10}{2} = 5[/tex]
Area of Semi-Circle:
[tex]C =\frac{ \pi r^2}{2}\\= \frac{3.14 * (5)^2}{2}\\=\frac{3.14*25}{2}\\=\frac{78.5}{2}\\= 39.25[/tex]
Area of Rectangle:
[tex]R = Length * Width\\R = 10*14\\R = 140[/tex]
The total area will be the sum of area of rectangle and the area of semi-circle
So,
[tex]Total\ Area = C + R\\= 39.25 + 140\\=179.25[/tex]
Rounding off to nearest tenth
The total area is: 179.3

1. Joanna is saving up for a new car. Her parents said that once she has $1000 saved up, they would help her
buy the car. Joanna has saved $300 in her bank account and $100 from her birthday money. She started
babysitting earning $10 per hour. How many hours of babysitting will she need to complete, so that her
parents will help buy her car.
9514 1404 393
Answer:
60 hours
Step-by-step explanation:
We want Joanna's total savings to be ...
bank account + gift + earnings = 1000
300 +100 +10h = 1000
10h = 600 . . . . subtract 400
h = 60 . . . . . . . .divide by 10
Joanna needs to babysit for 60 hours to earn the money she needs.

Consider the equation 5x + 7 = 2x + 28. Your tasks to explain the steps you would take, in
order, to solve the equation for x. Imagine that you are writing this for someone who is learning
about this process for the first time. You would be as specific as possible and write in complete
sentences.
Answer:
x=7
Step-by-step explanation:
Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.
Step 2: solve each side normally like this, 3x = 21
Step 3: to get x by itself divide 3 on both sides and you should get x=7
Here's a run through of the steps
5x+7=2x+28
-7 -7(subtract 7 from both sides
5x=2x+28-7
-2x -2x(subtract 2x from both sides)
5x-2x=28-7
3x=21
3x/3 = 21/3 (divide 3 from both sides)
x=7
A parent volunteer group is raising money by making custom hats to sell at
school activities. They plan to sell the hats for $12. Each hat costs $6 to
make. They spent $50 for advertising.

A. 12n - 6 - 50
O B. 50 - (12 – 6) n
O C. (12 - 6)n - 50
O D. 12 - 6n - 50
Answer:
B
Step-by-step explanation:
The answer is B because you minus 50 from 12 and 6.

Find all values of x in the interval [0, 2π] that satisfy the equation. (Enter your answers as a comma-separated list.)
6 sin2(x) = 3
Answer:
(15°, 165°)
Step-by-step explanation:
Given the equation 6 sin2(x) = 3, we are to find the value of x that satisfies the equation in the interval [0, 2π]
Given
6 sin2(x) = 3,
Divide both sides by 6
6 sin2(x)/6 = 3/6
sin2(x) = 1/2
2x = sin^-1(0.5)
2x = 30°
x = 30°/2
x = 15°
Since sin is positive in the second quadrant, x2 = 180-15
x = 165°
Hence the values within the interval are 15 and 165.
(15°, 165°)

A bicycle store costs $3600 per month to operate. The store pays an average of $80 per bike. The average selling price of each bicycle $120. How many bicycles must the store sell each month to break even?
The store must sell ____ bicycles each month to break even.
(Type a whole number)
Answer:
90 bikes.
Step-by-step explanation:
The bike store earns:
(120-80) = 40 dollars per bike sold.
Hence, to break even, the store must sell:
3600/40 = 90 bikes per month.
