Answer:
523.33 in^3
Step-by-step explanation:
A sphere is a 3-dimensional version of a circle. An example of a sphere is a ball
Volume of a sphere = [tex]\frac{4}{3}[/tex]π[tex]r^{3}[/tex]
Where
π = 3.14
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
diameter = 2r
Radius = 10 in / 2 = 5 inches
[tex]\frac{4}{3}[/tex] × 3.14 ×[tex]5^{3}[/tex] = 523.33 [tex]in^{3}[/tex]

A researcher believes that a new training program will increase test scores. Previous research shows that test scores increase 8 points between the first and second administration of the test being used. This researcher believes his training program will cause a significant increase, beyond the expected 8 points. If a paired-samples t test is used by this researcher, what value would he expect to be at the center of the comparison distribution, a distribution of mean differences
Answer:
value = 8
Step-by-step explanation:
when a paired-samples t test is used by this researcher we will write out the hypothesis as follows
H0: μd ≤ 8 ( null )
Ha: μd > 8 ( alternate )
Given the above Hypothesis
If a paired-sample T test is used by the researcher the value that would be at the center of the comparison will be 8

Answer:
3. 102
4. c
Step-by-step explanation:
For number 3:
(c^2 - a) + b becomes (10^2 - 3) + 5
10^2 = 100
100 - 3 + 5 = 102
For number 4:
Usually when you see distributive property, you're multiplying into parentheses. This time you're factoring out.
20c - 8d
It's not a, because that would be 20c + 8d
It's not b, because that would be 20c -32d
It is c, because 4 x 5c = 20 c and 4 x -2d = -8d
It's not d, because that would be 20c- 8cd
A rectangular sandbox will be constructed for the students at an elementary school. The sandbox will be filled to the top of the sandbox with sand. If each bag of sand contains 2.6 cubic feet of sand, how many bags of sand will need to be purchased to completely fill the sandbox.
Answer:
Approximately 19 bags of sand will be required.
Step-by-step explanation:
The statement misses the drawing of the sandbox which I have attached here. We can find the dimensions mentioned in the picture.
Length of box = 6.5 feet
Width of box = 5 ft
Height of box = 1.5 ft
Calculating the volume = V = length x width x height = 6.5 x 5 x 1.5 = 48.75 cubic ft
As given in the question, one sand bag has 2.6 cubic ft of sand
No of bags required = 48.75 / 2.6 = 18.75
A bag of Skittle contains 16 red, 4 orange, 10 yellow, and 12 green Skittles. What is the ratio of yellow to red Skittles?
Answer:
5:8
Step-by-step explanation:
yellow:red
10:16
simplified would be 5:8
***important note, when doing ratio, make sure to list the term that is asked for first. example: it's yellow to red skittles and not red to yellow. red to yellow would be 8:5 and that would be a wrong answer, so read carefully:)
Answer:
5:8
Step-by-step explanation: you can divide 10:16 by 2 to make 5:8, and that is the simplest form.

Prince Ivan rides Grey Wolf at a constant speed from King's Castle to the Magic Apple Garden in 5 hours. On their return trip to King's Castle, Grey Wolf runs at that original constant speed for the first 36 km. Then he runs the rest of the way 3 km/h faster. What was Grey Wolf's original speed if the return trip took 15 minutes less than the trip from King's Castle to the Magic Apple Garden?
Answer:
48 and 9
Step-by-step explanation:
36/x + 5x-36/x+3 = 5-0.25
Answer:
9 and 48 km/hr
Step-by-step explanation:
The Formula [tex]S=\frac{D}{T}[/tex] along with its variations are used
Let's say for the initial ride, the speed was x. Because the time was 5 hours, the distance was 5x km. Now for the return. For the first part, the speed remains x but our distance is 36km. So, our time is 36/x hours. For the second part, the speed is x+3 but our distance is 5x-36 (The total minus the distance of the first part.) So, our time is [tex]\frac{5x-36}{x+3}[/tex]. Now we have the equation [tex]\frac{36}{x} + \frac{5x-36}{x+3}=5-\frac{1}{4}[/tex] as our times add up to 5 hours minus 1/4 of and hour. Solving, we get x=9, x=48.

Plot the points D(-9,-6) E(-6,-3) F(0,-9)and dilate usinng a scale factor of 1/3 centered at the origin
Answer:
Step-by-step explanation:
Rule for the dilation of a point about the origin is,
(x, y) → (kx, ky)
Here, k = scale factor
Dilating points D, E and F about the origin by a scale factor 'k' = [tex]\frac{1}{3}[/tex]
D(-9, -6) → D'(-3, -2)
E(-6, -3) → E'(-2, -1)
F(0, -9) → F'(0, -3)
Now we can plot these points on graph.
Working together, Daniel and Donnie can clean the llama pen in 45 minutes. On his own, Daniel can clean the pen in an hour. How long does it take Donnie to clean the llama pen on his own?
Answer:
It takes him 15 minutes.
Step-by-step explanation:
Donnie clean the llama pen in 180 minutes on his own.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Daniel and Donnie can clean the llama pen in 45 minutes.
And, On his own, Daniel can clean the pen in an hour.
Now,
Let time to clean the llama pen in on his own = x minutes.
Since, Daniel and Donnie can clean the llama pen in 45 minutes.
So, In 1 minute, Daniel and Donnie clean the pen = 1/45
And, In 1 minute Daniel to work = 1/60
Thus, We can formulate;
1/x + 1/60 = 1/45
Solve for x as;
(60 + x) / 60x = 1/45
60 + x = 60x / 45
60 + x = 4x/3
180 + 3x = 4x
180 = 4x - 3x
180 = x
Thus, Donnie clean the llama pen in 180 minutes on his own.

A rectangular swimming pool is 6 it deep. One side of the pool is 3.5 times longer than the other. The amount of water needed to fill the swimming pool is
1344 cubic feet. Find the dimensions of the pool.
Answer:
8 feet by 28 feet by 6 feet
Step-by-step explanation:
So volume is length times width times height
It tells us that the volume is 1344 cubic feet (the water used to fill it)
And it also tells us that the height/depth (which are the same thing in this case) is 6ft
All we need now are length and width
We know that one of the sides is 3.5 times the other one. So we can just say length is x and width is 3.5x
So plugging that in, the equation becomes
[tex]3.5x*x*6=1344[/tex]
3.5 x times x is just 3.5x squared so
[tex]3.5x^2*6=1344[/tex]
divide both sides by 6
[tex]3.5x^2=244[/tex]
divide by 3.5
[tex]x^2 =64[/tex]
[tex]x=\sqrt{64}[/tex]
x = 8
So that means the one side is 8 feet long and the other side is 3.5 times that, which is 28 feet long.
So the dimensions of the pool are 8 feet by 28 feet by 6 feet

log x - log5^3 = 2log5^3
log x = 3log5 ^3
log x = log5 3^3.
x = 27
Answer:
x = 1953125
Step-by-step explanation:
log x - log 5^3 = 2 log 5^3
log x - 3 log 5 = 6 log 5
log x = 9 log 5 = log 5^9
x = 5^9
x = 1953125

Jenna borrowed $5,000 for 3 years and had to pay $1,350
simple interest at the end of that time. What rate of interest
did she pay?
Answer:
0.09 or 9%
Step-by-step explanation:
Formula:
I = Prt
r = I/(Pt)
Given:
I = 1350
P = 5000
t = 3
Finding r:
r = I/(Pt)
r = 1350/(5000 x 3)
r = 1350/15000
r = 0.09
0.09 or 9%
One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necessary round the nearest 10th
Answer:
17.7 cm
Step-by-step explanation:
One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necessary round the nearest 10th
To find the Hypotenuse of a right angle triangle, we solve using Pythagoras Theorem
Hypotenuse ² = Opposite ² + Adjacent ²
Hypotenuse = √Opposite ² + Adjacent ²
Opposite = 12 cm
Adjacent = 13 cm
Hence,
Hypotenuse = √12² + 13²
= √144 + 169
= 17.691806013 cm
Approximately = 17.7 cm
Therefore, the measure of the Hypotenuse is 17.7 cm

A store purchases a shirt for $16.89. The store marks up the shirt by 20%. Right now, they are having a sale for 40% off any item. What is the sale price with a 7.25% tax?
Answer:
$13.04
Step-by-step explanation:
First, multiply 16.89 by 1.2, 0.6, and 1.0725. You should get a weird number on your calculator saying 13.042458, but just round 2 to the 4 ( 4 stays the same) and remove all the other numbers to get $13.04
