A high-performance composite flywheel rotor can spin anywhere between 30,000 and 100,000 revolutions per minute. What
is the range of degrees through which the composite flywheel can travel in a minute? Write your answer in scientific
notation.
Answer:
Step-by-step explanation:
1 revolution will equal 360 degrees
Because of that 30,000 revolution would be 10,800,000 degrees
100,000 rev would equal 36,000,000 degrees
The range through which the composite flywheel rotates in one minute be denoted by ' F ' . (1.08 x 107)° F (3.6 x 107)°
The range of degrees the composite flywheel can travel in a minute is 2.52 × 10⁷ degrees/minute.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The range of revolutions per minute for the rotor is from 30,000 to 100,000, which means that the rotor can spin a total of 70,000 revolutions per minute (100,000 - 30,000 = 70,000).
To find the range of degrees through which the composite flywheel can travel in a minute, we need to multiply the range of revolutions by the number of degrees in one revolution.
A full revolution is 360 degrees, so the composite flywheel can travel in a minute :
70,000 revolutions/minute × 360 degrees/revolution = 25,200,000 degrees/minute
This can be written as 2.52 × 10⁷ in scientific notation.

Carlos is having a big party. He invited 5 times as many children as adults. He invited 15 adults. Which equation shows how to find the number of children invited to the party?
Answer:
75 children.
Step-by-step explanation:
If the amount of children is 5 times as many adults, you just need to multiply 15x5.
15x5=75 The number of children invited to the party is 75.
If you wanted this in an algebraic equation, it would look similar to this...
15(5)=x To solve for x, multiply 15 by 5.
75=x

Consider the following table that describes the mass of a kitten as weeks go by. If you know the kitten grows by 10% each week for the first 5 weeks, fill in the table for the values each week. Week Mass (grams) (start) 80
Answer:
Week Mass (gram)
(start) 80
1 88
2 96.8
3 106.48
4 117.128
Step-by-step explanation:
From the question we are told that
The mass of the kitten at the start week is m = 80 g
The rate at which the kitten grows is r = 0.10
Generally the mass of the kitten at the first week is mathematically represented as
[tex]m_1 = ( r * m) + m[/tex]
=>[tex]m_1 = ( 0.10 * 80 ) + 80 [/tex]
=>[tex]m_1 = 88 \ g [/tex]
Generally the mass of the kitten at the second week is mathematically represented as
[tex]m_2 = ( r * m_1) + m_1[/tex]
=>[tex]m_2 = ( 0.10 * 88 ) + 88 [/tex]
=>[tex]m_2 = 96.8 \ g [/tex]
Generally the mass of the kitten at the third week is mathematically represented as
[tex]m_3 = ( r * m_2) + m_2[/tex]
=>[tex]m_3 = ( 0.10 * 96.8) + 96.8 [/tex]
=>[tex]m_3 = 106.48 \ g [/tex]
Generally the mass of the kitten at the fourth week is mathematically represented as
[tex]m_4 = ( r * m_3) + m_2[/tex]
=>[tex]m_4 = ( 0.10 * 106.48) + 106.48 [/tex]
=>[tex]m_4 = 117.128 \ g [/tex]

Express as a trinomial.
(3x + 3)(3x + 8)
PLEASE HELPPP:)
Answer:
9x^2+33x+24
Step-by-step explanation:
The factors (3x + 3)(3x + 8) can be expressed as a trinomial 9x² + 33x + 24.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
To express (3x + 3)(3x + 8) as a trinomial, we can use the distributive property and FOIL (First, Outer, Inner, Last) method.
First, we multiply the first term of each binomial (3x) with the first term of the other binomial (3x), which gives us (3x)(3x) = 9x².
Next, we multiply the first term of one binomial (3x) with the second term of the other binomial (8), which gives us (3x)(8) = 24x.
Then we multiply the second term of one binomial (3) with the first term of the other binomial (3x) , which gives us (3)(3x) = 9x
Finally, we multiply the second term of each binomial (3) with the second term of the other binomial (8) , which gives us (3)(8) = 24
Now we add all the products to get the trinomial
9x² + 24x + 9x + 24 = 9x² + 33x + 24
Therefore, (3x + 3)(3x + 8) can be expressed as a trinomial 9x² + 33x + 24.

How much is a $20 shirt if it is 5% off?
Answer:
$19.00
Step-by-step explanation:
This is the answer because:
1) In order to know what 5% of 20 is, you have to do 20 x 5/100 = 100/100
2) Next, 100/100 = 1
3) Finally, we have to do 20-1 which is 19
Therefore, the answer is $19.00

Find the polynomial function of degree 3 such that f(2)=24 and x-1, x and x+2 are factors of the polynomial
Answer:
f(x) = 3x^3 + 3x^2 - 6x.
Step-by-step explanation:
Let:
f(x) = x(x - 1)(x + 2)
= x(x^2 + x - 2)
= x^3 + x^2 - 2x - this might be the answer or it might be some multiple of this.
Now f(2) = 24 so
24 = a(2^3 + 2^2 - 2(2)) where a is a constant.
24 = 8a
a = 3
So the function is
3( x^3 + x^2 - 2x)
= 3x^3 + 3x^2 - 6x.
find the measure of angle J .will mark brainiest
Answer:
<J=51°
Step-by-step explanation:
3x-2+4x-9+3x-9=180
10x-20=180
10x=200
x=20
<J=3x-9=3(20)-9=60-9=51°
Answer: Angle J = 51°
Step-by-step explanation: All angles add up to 180° in a triangle, so add every angle and set it equal to 180°.
(3x - 2) + (3x - 9) + (4x - 9) = 180
Add like terms:
10x - 20 = 180
Add 20 to both sides:
10x = 200
Divide both sides by 10:
x = 20
Now, plug x into angle J:
3(20) - 9
60 - 9
51
Angle J = 51°
