Answer:
100π
Step-by-step explanation:
V = (4/3)πr^3
(500/3)π = (4/3)πr^3
r^3 = 125
r = 5
Surface area of sphere = 4πr^2
= 4π(5^2) = 100π

Bartholomew and Maurice are buying school supplies. Bartholomew buys 5 notebooks and 6 binders for a total of $31.45. Maurice buys 4 notebooks and 8 binders for $38.60. Let n represent notebooks and b represent binders,what is the cost of a notebook?
Creating a system of equations, the cost of a notebook (n) will be: $1.25
n = note books.
b = binders.
Create a system of equation and solve for the variables.
Equation for school supplies bought by Bartholomew:
5n + 6b = 31.45 --> Eqn. 1Equation for school supplies bought by Maurice:
4n + 8b = 38.60 --> Eqn. 2Multiply Eqn. 2 by 6 and Eqn. 1 by 8.40n + 48b = 251.6 --> Eqn. 1
24n + 48b = 231.6 --> Eqn. 2
Subtract Eqn. 1 from Eqn. 2.16n = 20
Divide both sides by 16n = 1.25
Therefore, creating a system of equations, the cost of a notebook (n) will be: $1.25

A teacher wanted to fairly choose three students from a class of 23 to raise the school's flag. She assigned each student a two-digit number from 01 to 23. (Let's consider "01", "02", etc. to be two-digit numbers.) She then selected the following line from a random number table. 21215917917683658678870543168793205 Starting from the left, she used the line above to form two-digit numbers as follows. 212159 ... Using this new list and starting from the left, she chose three two-digit numbers from 01 to 23. She skipped numbers she had already chosen, the number 00, and numbers greater than 23. The students who were assigned these two-digit numbers were chosen. Which three students did the teacher choose? Student, Student, Student

Step-by-step explanation:
make x the subject
x-5y=3v
Step-by-step explanation:
Simplifying
x + -5y = 3v
Solving
x + -5y = 3v
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation.
x + -5y + 5y = 3v + 5y
Combine like terms: -5y + 5y = 0
x + 0 = 3v + 5y
x = 3v + 5y
Simplifying
x = 3v + 5y

I put $300 into a back account that gives me 2.5% simple interest. How much interest do i earn after 3 years
Answer:
$23.07
Step-by-step explanation:
Present Value(PV) = $300
Interest rate(r) = 2.5 % or 0.025
Year(d) = 3 years
Find Future Value first.
This is the formula:
FV = PV(1 +r)[tex]^{d}[/tex]
Put the values to it.
FV = 300(1 + 0.025)[tex]^{3}[/tex]
FV = 300(1.025[tex])^{3}[/tex]
FV = 300(1.076890625)
FV = 323.0671875 or $323.07
The future value is $323.07. Now subtract it to the present value to get the interest.
323.07 - 300 = $23.07
The interest is $23.07

Can someone help pls <3
Answer:
y = -x + 1
Step-by-step explanation:
Any point on an angle bisector has equal distance to both sides
Bisector line slope = rise/run = -1 (rise=run and moves from left to right)
equation: y = mx + b
y = -x+b
pass (2.-1)
-1 = -2 + b B = 1
y = -x+1
check: (y- -1)/(x-2) = -1
y+1 = -x+2
y = -x + 1

Answer:
44° (second option)
Step-by-step explanation:
Since the line bisects the angle, we can set them equal to each other and solve:
[Equation] 7x + 9 = 10x - 6
[Add 6 to both sides] 7x + 15 = 10x
[Subtract 7x from both sides] 15 = 3x
[Divide both sides by 3] 5 = x
Now, we will plug it into the expression for angle VXW,

what the common denominators for 1/4 + 1/2
Answer:
The common denominator is 4
Step-by-step explanation:
To answer this question of what is [tex]\frac{1}{4} +\frac{1}{2}[/tex]
We first have to find the LCM(Least Common Multiple) of the unlike denominators 4 and 2 which is 4
So we multiply the numerator and denominator [tex]\frac{1}{2}[/tex] by 2 so we can add with the same denominator [tex]\frac{1*2}{2*2}=\frac{2}{4}[/tex]
[tex]\frac{1}{4} +\frac{2}{4}=\frac{3}{4}[/tex]
