Answer:
7 x 7 x 7
Step-by-step explanation:
When raising a number or expression to an exponent, you are really just multiplying the number or expression by itself.
That means 7³ is 7 multiplied by itself 3 times.

Jack had $200 when he got to the festival. He spends $4 per ride. The equation T = 200 – 4R models his amount of money. If he has $100 left how many rides did he go on
Answer:
25
Step-by-step explanation:
Given the equation :
T = 200 - 4R
T = amount of money left ; if T = $100
R = number of rides
$100 = 200 - 4R
$100 - $200 = - 4R
-$100 = - 4R
R = 100/ 4
R = 25
25 rides

Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
Write your answer in the space below.
2. What is the MAD for company C's data? Show your work.
Write your answer in the space below.
3. Which company had the greatest mean number of deliveries?
Write your answer in the space below.
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Write your answer in the space below.
Answer:
Step-by-step explanation:
1. the company C used 10 drivers
2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/10
3. The groups that had the most deliveries where group A and B
4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4
By reading the dot plot,
Number of drivers used by company C in its sample = 10
Mean absolute deviation for company C's data = 2
Company B has the greatest mean number of deliveries.
The mean deliveries of company B is 4 times MAD of company A.
What is dot plot?Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.
Number of units used in the sample of a dot plot can be calculated by simple counting.
What is mean absolute deviation?The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.
We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.
Mean absolute deviation of company C = 20/10 = 2.
Mean A = 6
Mean B = 14
Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

Answer:
x = {-0.44, 1.69}
Step-by-step explanation:
Multiply by the denominator to eliminate the fraction.
3 = x(4x -5)
4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form
Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-5)\pm\sqrt{(-5)^2-4(4)(-3)}}{2(4)}\\\\x=\dfrac{5\pm\sqrt{73}}{8}\approx \{-0.443, 1.693\}[/tex]
Solutions rounded to hundredths are ...

mya bought some pizza for $12 each . f p represents the number of pizza she bough , what expression shows the total amount she spent ?
Answer:
Step-by-step explanation:
f(p)=12p
Answer:
12p
Step-by-step explanation:
Since each pizza costs $12 dollars and "p" represents how many pizzas she bought, you multiply 12 by "p" to get the total amount of money that she had spent.
which point represents the solution to the system

Answer: The volume is 528 cubic inches
Can i have brainliest?
Answer:
528 Cubic Inches
Step-by-step explanation:
The first thing you would do is, since the equation states that the total height of the bench is 8 inches, is place 4 as the height of the rectangular prism piece of the bench. Next you would use of the dimensions of each of pieces of the bench to calculate the area of each piece respectively using the equation l*w*h. The equations are 4*4*25 which equals 400, 4*4*4 which equals 64, and 4*4*4 which equals 64. Next, you would add them all together which gives you a grand total of 528 cubic inches.
If a bowling ball is dropped out of an airplane,
what will its speed (velocity) be after 3.4
seconds, assuming no air resistance? (Hint: Use
the equation v = 32t).
Answer: The velocity of the ball is 108.8 ft/s downwards.
Step-by-step explanation:
When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:
g = 32 ft/s^2
To get the velocity equation we need to integrate over time, to get:
v(t) = (32ft/s^2)*t + v0
where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)
Because it is dropped, the initial velocity is equal to zero, then we get:
v(t) = (32ft/s^2)*t
Which is the same equation that we can see in the hint.
Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:
v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s
The velocity of the ball is 108.8 ft/s downwards.
