Find the volume of half cylinder:
V = (pi x r^2 x h)/2 (I use pi = 22/7 for simplifying)
V = 22/7 x 6^2/2 x 35
V = 22/7 x 36/2 x 35
V = 22/7 x 35 x 18
V = 22 x 5 x 18
V = 1980cm^3
Find the volume of the rectangle:
V = 20 x 35 x 12
V = 240 x 5 x 7
V = 1200 x 7
V = 8400cm^3
Find the volume of the whole shape:
V = 1980 + 8400
V = 10380cm^3

Identify the number that does not belong with the other three. Explain your reasoning (24 points)
Answers
Answer:
See explanation
Step-by-step explanation:
The number that would not belong is [tex]\sqrt{48}[/tex] since it is irrational
Answer:
[tex]\sqrt{48}[/tex]
Step-by-step explanation:
Looking at the numbers, we can see that the first number, third, and fourth number are all rational numbers since they either repeat or terminate.
On the other hand, let's try and simplify the square root of 48:
[tex]\sqrt{48}=\sqrt{16\cdot3}=\sqrt{16}\cdot\sqrt3=4\sqrt3[/tex]
The square root of 3 is irrational. Therefore, 4 times the square root of 3 is also irrational. All of the given numbers are rational instead of the second one. So, the second number does not belong .

What’s the measure of X in this short answers are fine
Answers
Answer:
28 = x
Step-by-step explanation:
62 = angle BAC since they are vertical angles
angle ABC is a right angle since KL is perpendicular to FG
Adding the angles in triangle ABC
BAC + ABC + BCA = 180
62 + 90 + BCA = 180
152 + BCA = 180
BCA = 180-152
BCA = 28
BCA = x since they are vertical angles
28 = x
How do I solve for y in this equation? 3xy-28=15x
Answers
Answer:
x = 28/(3y -15)
Step-by-step explanation:
Put the x-terms on the same side of the equal sign and everything else on the other side. Divide by the coefficient of x.
3xy -28 = 15x . . . . . . given
-28 = 15x -3xy . . . . . subtract 3xy
-28 = x(15 -3y) . . . . . factor out x
-28/(15 -3y) = x . . . . . . divide by the coefficient of x
We prefer to have a positive sign where possible, so we can multiply this by -1/-1 to get ...
x = 28/(3y -15)

25b +15b combine like terms
Answers
Answer:
40b
Step-by-step explanation:
25 + 15 = 40
Answer:
40b
Step-by-step explanation:
We are given the expression:
25b+15b
and asked to simplify.
To simplify, we must combine like terms. Let's analyze the terms.
25b ⇒ has a variable "b"
15b ⇒ also has a variable "b"
The like terms in this expression are the terms with a variable, b.
To combine like terms, add the coefficients and leave a b on the end.
(25+15)*b
(40)*b
40b
The expression 25b+15b simplified is 40b.

[tex]2.\ 3x = 1[/tex]
For the first expression, we multiply both sides by 3
[tex]3 * \frac{x}{3} = 1 * 3[/tex]
[tex]x = 1 * 3[/tex]
[tex]x = 3[/tex]
For the second; divide both sides by 2

What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
In mathematics, adding a negative number and a positive number involves combining two quantities with opposite signs. When we add a negative number and a positive number, we can think of it as "subtracting the absolute value of the negative number from the positive number."
For example, if we have -3 + 5, we can rewrite it as 5 - 3, which equals 2. In this case, we are subtracting the absolute value of the negative number (3) from the positive number (5).
Similarly, if we have -7 + 2, we can rewrite it as 2 - 7, which equals -5. In this case, we are subtracting the absolute value of the negative number (7) from the positive number (2), but since the negative number has a larger absolute value, the result is negative.
So, the result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

A manufacturer drills a hole through the center of a metal sphere of radius R = 8. The hole has a radius r. What value of r will produce a ring whose volume is exactly half the volume of the sphere? (Round your answer to two decimal places.)
Answers
Answer:
New radius(r) = 3.65 (Approx)
Step-by-step explanation:
Given:
Radius of sphere(R) = 8
Find:
New radius(r)
Computation:
Volume of sphere = (4/3)πR³
Volume of sphere = (4/3)π(6)³
Volume of sphere = 288π
Volume of ring = (4/3)π(R²-r²)³/²
Half volume of sphere = Volume of ring
288π / 2 = (4/3)π(R²-r²)³/²
144 = (4/3)(6²-r²)³/²
108 = (6²-r²)³/²
New radius(r) = 3.65 (Approx)

Peter withdrew 1000 dollars from his bank account today. He uses 500 to fix his car. Then, he divided the money into 5 equal parts and gave away 4 parts and kept 1 part for himself. Finally, he took his wife to the restaurant and spent 60 dollars on meals. Write a numerical expression to represent this situation and then find how much money Peter has now?
Answers
Answer:
ok he has $40 left
Step-by-step explanation:
1000-500 = 500
500 - 400 = 100
100-60 = 40
Answer:
Money with Peter = $ 40
Step-by-step explanation:
Let 'x' be the money left with Peter
Money left with Peter after fixing his car = 1000 - 500 = 500
500 is divided into 5 equal parts and 4 parts he gave away. 500 - 400 = 100
x = (1000 - 500) - 400 - 60
= 500 - 400 - 60
= 100 - 60
x =$ 40
