Find the surface area of the sphere (I can't upload the pic but I'll give the radius).
Radius 7 m
A. 56π m²
B. 784π m²
C. 392π m²
D. 196π m²
Answer:
D
Step-by-step explanation:
This is because the formula is 4×pi×r^2
So 4×pi×7^2
(7^2=49) now plug that in: 4×pi×49
Combine like terms: 4×49=196
Plug that into the equation: 196pi

Find the slope of the line passing through the points (-4, 2) and (3, 2)
Answer:
0
Step-by-step explanation:
The slope of a line is also known as the change in the line. it is often referred to as ([tex]\frac{rise}{run}[/tex]) and can be found using the formula, ([tex]\frac{y_2-y_1}{x_2-x_1}[/tex]). Substitute in the given points and solve for the slope,
[tex]\frac{(2)-(2)}{(3)-(-4)}[/tex]
Simplify,
[tex]\frac{0}{3+4}\\\\\frac{0}{7}[/tex]
The slope of the line is (0).

mrs. Kenny teaches a ceramics class. She finds that she has 7/8 of a pound clay project. The project requires 1/6 of a pound. how many projects can Mrs. Kenny complete without running out of clay?
Answer:
5 1/4
Step-by-step explanation:
Mrs. Kenny can complete 5 projects with 1/4 of a pound of clay left over.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
To find out how many projects Mrs. Kenny can complete with 7/8 pound of clay, we need to divide 7/8 by 1/6:
= (7/8) ÷ (1/6)
To divide fractions, we need to invert the second fraction and multiply:
= (7/8) × (6/1)
Simplifying the fractions, we get:
(7 × 6)/(8 × 1) = 42/8 = 5 1/4
Thus,
Mrs. Kenny can complete 5 projects with 1/4 of a pound of clay left over.

Jordan earned $200 this month delivering newspapers. His mom said he must put 20% into his savings account. He wants to buy headphones that cost $ 99.95 and two shirts that cost \$17 each. He also has to pay 7% sales tax on his purchases . Jordan said, "No problem. I will put 20% into savings , buy the things I want, and still have about $10 left." Use estimation to determine if Jordan's calculation is reasonable. Show your work.
Answer:
Yes, his calculation is reasonable. He will have about $16.67 left.
Step-by-step explanation:
200 - (200 * .2) = $160 Subtract money for savings
99.95 + (99.95 * .07) + (17*2) + (17 * .07) + (17 * .07) = $143.33 Add taxes
160 - 143.33 = $16.67 Subtract money for purchases from money left after savings

Find the values of the measures shown when each value in the data set increases by 25. Mean: 109 Median: 104 Mode: 96 Range: 45 Standard deviation: 3.6
Answer:
The new values are as follows:
Mean: 134
Median: 129
Mode: 121
Range=45
Standard Deviation=3.6
Step-by-step explanation:
When a k real number is added to all the elements of the dataset, the new measures of center (mean, median, and mode) are simply found by adding the value k to the previous values. Thus
[tex]Mean_{new}=Mean_{old}+k[/tex]
Here [tex]Mean_{old}[/tex] is 109 and k is 25 thus
[tex]Mean_{new}=Mean_{old}+k\\Mean_{new}=109+25\\Mean_{new}=134[/tex]
Similarly
[tex]Median_{new}=Median_{old}+k[/tex]
Here [tex]Median_{old}[/tex] is 104 and k is 25 thus
[tex]Median_{new}=Median_{old}+k\\Median_{new}=104+25\\Median_{new}=129[/tex]
Also
[tex]Mode_{new}=Mode_{old}+k[/tex]
Here [tex]Mode_{old}[/tex] is 96 and k is 25 thus
[tex]Mode_{new}=Mode_{old}+k\\Mode_{new}=96+25\\Mode_{new}=121[/tex]
When a k real number is added to all the elements of the dataset, the new measures of variation (range and standard deviation) remain the same thus.
[tex]Range_{new}=Range_{old}\\Range_{new}=45[/tex]
Similarly
[tex]Standard\ Deviation_{new}=Standard\ Deviation_{old}\\Standard\ Deviation_{new}=3.6[/tex]
So the new values of mean, median, mode, range, and standard deviation are 134, 129, 121, 45, and 3.6 respectively.

Answer:
65 degrees
Step-by-step explanation:
I recently answered a question in detail that was similar to this one. Feel free to look at my answered questions for it.
For this one, the easiest way to think about it is this. The line on which both angle 4 and angle 1 sit is a straight line, that makes them supplementary angles which is just a fancy word that means if you add them together they equal 180.
(angle 4) + (angle 1) = 180
And if (angle 1) = 115, then that means
(angle 4) = 180 - 115
(angle 4) = 65

Suppose that when your friend was born, your friend's parents deposited $9000 in an account paying 6.9% interest compounded . What will the account balance be after 17 years?
Answer:
the account balance after 17 years is $27,981.02
Step-by-step explanation:
Given that
The deposited amount i.e. $9,000
The Rate of interest is 6.9%
Time period = 17 years
We need to find out the account balance after 17 years
As we know that
Future value = Present value × (1 + rate of interest)^time period
= $9,000 × (1 + 6.9%)^17
= $27,981.02
Hence, the account balance after 17 years is $27,981.02
a football team gains 9 1/2 yards on their first play then lose 10 yards for a penalty they lose 5 yards and then gain 7 yards on the next two plays what is the teams overall gain or loss and did rhey make a first down (10+ yards)?
Answer: No
Step-by-step explanation: Because if the team lost 10 yards from 9 1/2 then they would be negative yards if they lose 5 yards they will have 5 1/2 and if they gain 7 yards their total will be 1.5 so they never made it to 10+ yards.

100, 121, 105, 113, 108, X ; mean = 112.
Answer:
x = 135
Step-by-step explanation:
(100 + 121 + 105 + 113 + 108 + x) /6 = 112
(547 + x) /6 = 112
547 + x = 112 × 6
547 + x = 672
x = 672 - 547
x = 135

Rita is starting a running program. The table shows the total number of miles she runs in different weeks. What is the equation of the line of best fit for the data? State each number to the thousandths place.
Step-by-step explanation:
Y = 1.671 X + 4.699
The equation of best fit data is Y = 1.671 X + 4.699
What are fit equations?
Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.
The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.
