What would be the volume of a sphere if the radius is 6 in? Round to nearest tenth if needed
Answer:
904.8cm
Step-by-step explanation:
The volume of a sphere is given as
[tex] \frac{4}{3}\pi {r}^{2} [/tex]
There is only one variable, the radius, which we are given in the problem.
since the radius is 6 cm, we can plug that in to the formula
[tex] \frac{4}{3} \pi {6}^{2} [/tex]
Put this into the calculator, and we see that the volume is 904.8cm rounded to the nearest tenth.
If mpho is the 50th fastest and slowest runner in her school,how many students are there in her school
Answer:
Step-by-step explanation:
i need points lol
There are 99 students in her school.
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;
mpho is the 50th fastest and slowest runner in her school.
Now,
Since, mpho is the 50th fastest and slowest runner in her school.
Hence, Total number of students = (50 + 50) - 1
= 100 - 1
= 99
Thus, There are 99 students in her school.

Can someone explain to me how Slope Rise over Run works? I just don’t understand it no matter how many times I look into it.
Answer:
slope= rise over run means divide rise by run
Answer:
when there is a linear equation and line. first, find where you see a point that has whole numbers. graph them or circle them. Next, go to point to pint using the lines. do not use the slanted line. go up (rise) and count how many boxes you passed (be careful it could go by 2's) and then go across to the other point (run). count how many boxes you passed. now you put the up number or rise number over the run number. Rise/run. you'll get a fraction, simplified it if needed.
or do slope form which is just find 2 points that have whole numbers. Label the first one (x1,y1) and the second one (x2,y2) the you do (Y2 - Y1) over (X2 - X1). you'll get a fraction and you'll simplified it if needed

last year janes wages were $80 per week her wages are now $86 per week.Calculate the percentage increased.
Answer:
7.5%
Step-by-step explanation:
86 - 80 / 80 = 0.075
so 7.5%
The percentage increase in wages of from last year to now is 7.5%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, last year janes wages were $80 per week her wages are now $86 per week.
Now, the difference in wage =86-80
= 6
The percentage increase
= 6/80 ×100
= 7.5%
Therefore, the percentage increase in wages of from last year to now is 7.5%.

Solve the right triangle. Round your answers to the nearest tenth.
Answer:
A=42 degrees a=13.5 c=20.2
Step-by-step explanation:
Knowing that all the angles in a triangle add up to 180, we simply subtract 90 and 48 from 180 to figure out angle A.
For side a and c we can us trig to figure them out. Sin is equal to opposite over hypotenuse so the sin(48)=15/c, rearranging this equation we can do 15/sin(48)=c to figure out the length of side c
For a we use tan, which is opposite over adjacent. So we can make the formula tan(48)=15/a then rearrange this to 15/tan(48)=a to figure out the length of a

the common factor of 6x 66xy
Answer:
6x and 1x or x
Step-by-step explanation:
the highest common factor of 6x and 66xy in 6x
6x ÷ 6x = 1
66xy ÷ 6x = 11y
the lowest common factor of 6x and 66xy is 1x or x
6x÷ 1x =6
66xy÷ 1x = 66y
6x÷ x = 6
66xy ÷ x = 66y

Business owners use percents to calculate markup, discount, and sales tax. A shoe store owner buys a pair of shoes for $20. There is a sale on the item for 20% off.
Answer:
$16
Step-by-step explanation:
Given data
The cost price of the shoe= $20
Discount = 20%
Let us find the amount of the 20% discount
=20/100*20
=0.2*20
=$4
Hence the selling price will be
=20-4
=$16

y=-x^2+73x-520
y=−x
2
+73x−520
Answer:
36.5
Step-by-step explanation:
y= -x²+73x-520
which can be represented as ax²+bx+c
a= -1, b= 73, c = -520
for maximum value of y,
the formula is
c - (b² / 4a)
= -520 - (73² / 4×(-1))
= -520 - (5329 / -4)
= -520 + 1332.25
= 812.25
Solving for x,
812.25 = -x²+73x-520
or, x²-73x+ 1332.25 = 0
Solving,
x= 36.5
Jeff drew a circle inside a square, as shown below.

square not covered by the circle?
Answer:
3.14
Step-by-step explanation:
Answer:
Ok, I didn't find the graph but jeff can use the diameter of the circle as the diamation of the square
If the radius is (r) so the area is
A = d * d
which of the following statements are true
A tangent line is perpendicular to the radius of a circle at the point of tangency.
A tangent line is perpendicular to the diameter of a circle at the point of tangency.
A tangent line is the perpendicular bisector of the radius of a circle.
A tangent line intersects a circle at one point.
A tangent line intersects a circle at two points.
Every circle has exactly one tangent line to that circle.
The tangent line and radius or diameter of the circle intersect at a right angle and the tangent intersects the circle at a single point only. Then the correct option is A, B, and D.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The tangent line and radius or diameter of the circle intersect at a right angle.
And the tangent line intersects the circle at a single point only.
The number of the tangent line depends on the point from which the tangent is drawn.

Answer:
37
Step-by-step explanation:
Pythagorean theorem
Answer: 37 (side AB)
Step-by-step explanation:
For this question you would have to use Pythagoras' theorem. Pythagoras' theorem states that c²=a²+b².
so when you put the numbers in the formula you get c²=12²+35²
12²=144
35²=1225
c²=144+1225
c²=1369
Then because you want c on it's own you square root 1369.
c=√1369
c=37

Suppose you know the minimum, lower quartile, median, upper quartile, and maximum values for a set of data. Explain how to create a box plot for the data set.
NO LiNKS OR BE REPORTED
Answer:
For some sets of data, some of the largest value, smallest value
, first quartile, median, and third quartile may be the same. For instance, you might have a data set in which the median and the third quartile are the same. In this case, the diagram would not have a dotted line inside the box displaying the median. The right side of the box would display both the third quartile and the median. For example, if the smallest value and the first quartile were both one, the median and the third quartile were both five, and the largest value was seven, the box plot would look like:
In this case, at least
25
25
% of the values are equal to one. Twenty-five percent of the values are between one and five, inclusive. At least
25
25
% of the values are equal to five. The top
25
25
% of the values fall between five and seven, inclusive.
Answer:
First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.
Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.
Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.
Voila, my friend. You have a box plot.
