Part A
Which measurements do you need to know to find the volume of a cylinder?
Part B
Since the base of the refraction cup is a half circle, how can you find the radius? What is the radius?
Part C
If you put two refraction cups together, what three-dimensional shape do you have?
Part D
The formula for the volume of a cylinder is v= 3.14r^2h.
What is the approximate volume of two refraction cups use 3.14 for pi.
Part E
Since one refraction cup is half of a cylinder, how could you change the formula for the volume of a cylinder to calculate the volume of a refraction cup?
Part F
Using the equation from Part E, what is the approximate volume of one refraction? What is the relationship between this value and the value from part D? Use 3.14 for pi.
Answers
Answer:
Part A: To find the volume of a cylinder, we need the dimensions of the cylinder such as the radius of the base of the cylinder and the height of the cylinder.
Part B: We have given the base of the refraction cup as a half-circle, we can calculate the radius of the base.
The diameter is given as 8 cm so, the radius would be half of the diameter.
r = 4cm
Part C: If you put two refraction cups together, we get the full three-dimensional shape that is a circle.
Part D: The formula for the volume of a cylinder is V=pi r^2 h.
Part E: The volume of a refraction cup =
= 4/3 (3.14)(8)
= 33.49
Part F: The relationship between the value D and the value from Part D is as follows
The volume of a cylinder = 3 times the volume of a refraction cup

What is the answer?
Answers
Answer:144
Step-by-step explanation:
Use a calculator
or 1/2 x 288 = 288/2 = 144
Answer: 144
Step-by-step explanation:
I'm assuming that the "x" in this statement is a multiplication symbol.
Multiplying any number by 1/2 or 0.5 is the same thing as dividing it by 2.
Therfore the answer is 288/2 which is 144.
pattern x starts with the number 0 and follows the rule "add 2". pattern y starts with the number 30 and follows the rule "subtract 5". place a check mark in the box next to each ordered pair that that could be formed by the corresponding terms in the patterns

Janice has $2.46 worth of coins in her pocket. The coins are of four different denominations, and she has the same number of each denomination. What are the four denominations, and how many of each does she have?
Answers
If Janice has pennies, nickels, dimes, and quarters. Using trial and error, I found the following results:
1 of each coin: 0.01 + 0.05 + 0.10 + 0.25 = 0.41
2 of each coin: 0.02 + 0.10 + 0.20 + 0.50 = 0.82
3 of each coin: 0.03 + 0.15 + 0.30 + 0.75 = 1.23
4 of each coin: 0.04 + 0.20 + 0.40 + 1.00 = 1.64
5 of each coin: 0.05 + 0.25 + 0.50 + 1.25 = 2.05
6 of each coin: 0.06 + 0.30 + 0.60 + 1.50 = 2.46
Based upon these results, Janice has 6 of each coin.
Solution #2:
If we let x = the number of coins, then we can set up the equation
0.01x + 0.05x + 0.10x + 0.25x = 2.46 combine like terms
0.41x = 2.46 divide both sides of the equation by 0.41
x = 6
This confirms that Janice has 6 coins of each denomination including pennies, nickels, dimes and quarters.
The number of the same coin that she has will be 6.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Janice has $2.46 worth of coins in her pocket. The coins are of four different denominations, and she has the same number for each denomination.
If there are any pennies, nickels, dimes, or quarters on Janice. Trial and error led me to the following conclusions:
1 of each coin: 0.01 + 0.05 + 0.10 + 0.25 = 0.41
2 of each coin: 0.02 + 0.10 + 0.20 + 0.50 = 0.82
3 of each coin: 0.03 + 0.15 + 0.30 + 0.75 = 1.23
4 of each coin: 0.04 + 0.20 + 0.40 + 1.00 = 1.64
5 of each coin: 0.05 + 0.25 + 0.50 + 1.25 = 2.05
6 of each coin: 0.06 + 0.30 + 0.60 + 1.50 = 2.46
Based upon these results, Janice has 6 of each coin.
Let x be the number of coins. Then we can set up the equation will be
0.01x + 0.05x + 0.10x + 0.25x = 2.46
0.41x = 2.46
x = 6
The number of the same coin that she has will be 6.

You may realize that we have not yet discussed the distance around a very important geometric shape: a circle! The distance around a circle has a special name called the circumference. To find the circumference of a circle, we use this formula: C = 2πr
In this formula, π is pronounced “pi,” and is defined as the circumference of a circle divided by its diameter:
π
=
C
d
. We usually replace π with the approximation 3.14. The letter r represents the radius of the circle.
Let’s see where the formula for circumference comes from. Figure 4 shows a generic circle with radius r.

An expression is a sort of equation but without any number after the equal to sign
so 2x-7 would be an expression but 3x would not be a expression
3x is just a term
2+7 would also not be an expression because this can be simplified into 9 which is not a expression
2x-7=14 is not a expression cuz it has the equal to sign
-14 is not a expression because its a single number

-2x + 1 = -x + 8 solve for X?
Answers
Answer:
x = -7
Step-by-step explanation:
-2x + 1 = -x + 8
* isolate the variable using inverse operations *
step 1 add 2x to each side
-2x + 2x cancels out
-x +2x = x
now we have 1 = x + 8
step 2 subtract 8 from each side
8 - 8 cancels out
1 - 8 = -7
we're left with x = - 7
Suppose {an) is an arithmetic sequence with a16=12 and a7=30. Find a9.
Answers
Answer:
a9 = 26
Step-by-step explanation:
nth term of an arithmetic sequence an = a + (n-1)d
a16 = a+15d = 12.... 1
a7 = a+6d = 30.....2
Subtract
15d - 6d = 12 - 30
9d = -18
d =-18/9
d = -2
Substitute d = -2 into 1
a + 15d = 12
a+15(-2) = 12
a - 30 = 12
a = 12 + 30
a = 42
Get a9;
a9 = a+8d
a9 = 42+8(-2)
a9 = 42 - 16
a9 = 26
hence the 9th term of the sequence is 26

(b) For what value(s) of c will the system have more than one real solution?

Answer:
(a) c = 4
(b) c < 4
(c) c > 4
Step-by-step explanation:
(a) The solutions to the system of equations can be found by substituting one expression for y into the other equation:
3x^2 -5x = 2x^2 -x -c
x^2 -4x +c = 0 . . . . . . . subtract the right side expression
The discriminant is
d = b^2-4ac = (4)^2 -4(1)(c) = 16-4c.
The system will have exactly one solution when d = 0.
16 -4c = 0
4 -c = 0

(b) There will be more than one real solution when d > 0
4 -c > 0
c < 4 . . . . two real solutions

Find all the missing elements : C=120degrees
b= 5
c=11
Answers
Answer:
A = 36.8°
B = 23.2°
a = 7.6
Step-by-step explanation:
Given:
C = 120°
b = 5
c = 11
Required:
Find A, B, and a.
Solution:
✔️To find B, apply the Law of Sines
[tex] \frac{sin(B)}{b} = \frac{sin(C)}{c} [/tex]
Plug in the values
[tex] \frac{sin(B)}{5} = \frac{sin(120)}{11} [/tex]
Cross multiply
Sin(B)*11 = sin(120)*5
Divide both sides by 11
[tex] sin(B) = \frac{sin(120)*5}{11} [/tex]
[tex] sin(B) = \frac{sin(120)*5}{11} [/tex]
Sin(B) = 0.3936
B = [tex] sin^{-1}(0.3936) [/tex]
B = 23.1786882° ≈ 23.2° (nearest tenth)
✔️Find A:
A = 180° - (B + C) (sum of triangle)
A = 180° - (23.2° + 120°)
A = 36.8°
✔️To find a, apply the Law of sines:
[tex] \frac{sin(A)}{a} = \frac{sin(B)}{b} [/tex]
Plug in the values
[tex] \frac{sin(36.8)}{a} = \frac{sin(23.2)}{5} [/tex]
Cross multiply
a*sin(23.2) = 5*sin(36.8)
Divide both sides by sin(23.2)
[tex] a = \frac{5*sin(36.8)}{sin(23.2) [/tex]
a = 7.60294329 ≈ 7.6 (nearest tenth)
