Answer:
V = 286319.465 cm3
Step-by-step explanation:
First, you have to find the radius to be able to find the volume of a sphere.
The equation for the area of a circle is pi r^2 so you have to so some algebra.
5252 = pi r ^2
5252/pi = r^2
1671.76352 = r^2
sqrt(1671.76352) = r
r = 40.8872048
then you do the equation for the volume of a circle which is 4/3 pi r^3
4/3 pi (40.8872048)^3
4/3 pi 68353.7373
4/3 214739.599
286319.465
V = 286319.465 cm3

george started a coin collection. his dad gave him 75 coins. each month he will add 20 coins. Which equation can be used to find y, the total number of coins in george's collection after x months? A. y = 75x + 20x By = 20x + 75 C. y = 75x - 20 D. 20x - 75
Answer: B
Step-by-step explanation: Hope this helps!
he got a one time thing of 75 coins and now gets 20 coins for each month which explains 20x. (X being the number of months)
The equation that could be used for determining the y should be option B y = 20x + 75
Calculation of an equation:
Since dad gave him 75 coins. each month he will add 20 coins.
Here we assume a number of months be x
So, the equation is
y = 20x + 75
Therefore, we can conclude that The equation that could be used for determining the y should be option B y = 20x + 75

Answer:
From the above attachment we can conclude that,
[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

2. Mary answered 6 questions correctly on her Biology test.
She answered 20% of the questions correctly. In total, how
many questions were on the Biology test?
Answer:
60
Step-by-step explanation:
if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20
Answer:
The Answer is 30 questions in total.
Step-by-step explanation:
1. The first thing you would want to do is to break down this question.
For every 6 questions, this is 20% of the test done.
2. You now would want to divide 100% (the full amount on the test) by 20%.
100%/20% = 5
3. Now, multiply both to get your answer.
6·5= 30
20%x5= 100%.
Therefore, the total amount of questions on the test is 30 questions.
Identify the unit rate in the graph.
A. 40mph
B. 75mph
C. 50mph
D. 25mph
Answer:
The unit rate is C. 50mph
Step-by-step explanation:
Take two points from the line,
I took points (1, 50) and (2, 100).
Then plug them into this formula:
y2-y1/x2-x1
Solve:
(100- 50)/(2 - 1)
100 - 50 = 50
2 - 1 = 1
50/1 = 50
So, you get C. 50mph
Answer:
The answer would be C. 50mph

Lupita completed the square to solve the equation 0 = x2 - 6x +13 as follows.
Lupita made a mistake. In which step did the error occur and what was the error? Finally
complete the problem with the mistake fixed and give the solutions to the equation.
The solution to the equation is x = ±[tex]\sqrt{2}[/tex]i +3
What is a quadratic equation ?A quadratic equation is an algebraic equation which has highest degree of 2 and it has 2 roots.
In the given question
x² - 6x +13 = 0
x² - 2.x.b + 13 = 0 (-2.x.b = -6x ↔ b = 3)
(x - 3)² + 13 = 9 ( we have added 9 on r.h.s
because b² = 9 is added on l.h.s)
(x-3)² = -4
x - 3 = ±[tex]\sqrt{2}[/tex]i
x = ±[tex]\sqrt{2}[/tex]i +3
She made a mistake in the second step she should have added +9 on the right hand side because we have an additional 9 on the left hand side because of the perfect square we have made to make both sides balanced.

The rotation that the triangle DEF underwent is defined as follows:
180º around the origin.
RotationA rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.
A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:
90° clockwise rotation: (x,y) -> (y,-x)90° counterclockwise rotation: (x,y) -> (-y,x)180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y)270° clockwise rotation: (x,y) -> (-y,x)270° counterclockwise rotation: (x,y) -> (y,-x)In this problem, the coordinates are given as follows:
Original: (-3,5).Image: (3,-5).Hence the rule is:
(x,y) -> (-x, -y).
Meaning that a rotation of 180º around the origin was done.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If out of 28 students, 12 students packed their lunch.
The number of students who packed their lunch out of 336 students is 144 students.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
3 miles in 3 hours.
1 mile in one hour.
We have,
In a class of 28 students, 12 students packed their lunch.
We can write this as:
28 students = 12 students packed lunch ______(1)
We have to make 28 students into 336 students.
This can be done by multiplying 12 on both sides of the equation (1)
Multiply 12 on both sides.
12 x 28 students = 12 x 12 students packed lunch
336 students = 144 students packed lunch
Thus,
The number of students who packed their lunch out of 336 students is 144 students.
