Answer with step-by-step explanation:
Let us find the perfect cubes between 1 to 100.
We know that, 1
3
=1,2
3
=8,3
3
=27,4
3
=64 and the rest numbers i.e. 4,5,6,.... have their cubes greater than 100.
So, only these four numbers have their cubes between 1 to 100.
Thus, there are 4 perfect cubes from 1 to 100.
Now, let's find the cubes between −100 to 0
We know, 0
3
=0,(−1)
3
=−1,(−2)
3
=−8,(−3)
3
=−27,(−4)
3
=−64 and the rest numbers have their cubes less than −100
So, only these 5 numbers have their cubes between −100 to 0 and 4 perfect cubes are there from 1 to 100.
Thus, there are 9 perfect cubes from −100 to 100.

A company that sells yoga mats estimates its annual profit using the equation below, where x represents the wholesale price in dollars of 1 yoga mat, and P = annual profit in thousands of dollars.
P = 10x? - 280x + 1,600 When the expression on the right side of this equation is factored completely, which best describes the meaning of the factors?
The annual profit is zero at a wholesale price of $80 and zero at a wholesale price of $200.
The annual profit is zero at a wholesale price of $8 and maximized at a wholesale price of $20.
The annual profit is zero at a wholesale price of $80 and maximized at a wholesale price of $200.
The annual profit is zero at a wholesale price of $8 and zero at a wholesale price of $20.
Answer: (d)
Step-by-step explanation:
Given
Annual profit is given by
[tex]P=10x^2-280x+1600[/tex]
When it is factored then,
[tex]\Rightarrow 10x^2-280x+1600=0\\\Rightarrow 10\left( x^2-28x+160\right)=0\\\Rightarrow x^2-20x-8x+160=0\\\Rightarrow x(x-20)-8(x-20)=0\\\Rightarrow (x-8)(x-20)=0\\\Rightarrow x=8,20[/tex]
On factorization, we get that annual profit is zero at a whole prize of $8 and $20.
Which answer choice shows that the commutative property does not hold for matrix multiplication?
Given:
The matrix statements in the options.
To find:
The answer choice that show the commutative property does not hold for matrix multiplication.
Solution:
We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then
[tex]AB\neq BA[/tex]
Let us assume,
[tex]A=\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\text{ and }B=\begin{bmatrix}1&3\\8&5\end{bmatrix}[/tex]
According to the above property of the matrix, we get
[tex]\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\begin{bmatrix}1&3\\8&5\end{bmatrix}\neq \begin{bmatrix}1&3\\8&5\end{bmatrix}\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}[/tex]
Therefore, the correct option is B.

Given that Jamie wants to make an 80, or B, test average in her class.
She scored 75 and 82 on her last 2 tests.
we need to find the lowest grade she can make on her last test to finish with an 80 test average
Let x be the e lowest grade she can make on her last test to finish with an 80 test average
75+82+x/3=80
157+x=240
Subtract 157 from both sides
x=83
Hence, 83 is the lowest grade she can make on her last test to finish with an 80 test average.

Answer:
f(x)= (x-5)(x+6)
Step-by-step explanation:
First, we find the factors of -30 that add up to +1
We can use 6 and -5
6+(-5)=1
f(x)= x^2+6x - 5x-30
then, we do group factorization
f(x)= x(x+6)- 5(x+6)
f(x)= (x-5)(x+6)

The mean age of 5 people in a room is 33 years. A person enters the room. The mean age is now 37. What is the age of the person who entered the room?
Mean is the average,
The total ages with 5 people would be 5 x 33 = 165
the total ages with the 6th person is 6 x 37 = 222
The age of the 6th person is 222 - 165 = 57 years old.
Find the area of this shape
Answer:
433 m²
Step-by-step explanation:
Find the side length of the square first.
Apply Pythagoras Theorem on 1 of the triangles on the right, to find its remaining side.
[tex] \sqrt{ {12}^{2} - {9.6}^{2} } [/tex]
=[tex] \sqrt{51.84} [/tex]
= 7.2 m
Therefore the side of the square is
7.2 ×2
= 14.4 m
The area of the square
= 14.4²
= 207.36 m²
You are able to find the area if of the 2 triangles.
(7.2 × 9.6)÷2 ×2
= 69.12 m²
The height of the pentagon
= 25.4 - 7.2
= 18.2 m
The area of the pentagon
= (10+7.2) × 18.2 ÷ 2
= 156.52 m²
Add up the areas of the 3 polygons.
The area of the shape
= 207.36 + 69.12 + 156.52
= 433 m²

A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20
Complete Question
A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20 dozen?
Answer:
11 2/3 cups of flour
Step-by-step explanation:
From the above question:
6 dozen = 3 1/2 cups of flour
20 dozen = x
Cross Multiply
6 dozen × x = 20 dozen × 3 1/2 cups of flour
x = 20 dozen × 3 1/2 cups of flour/6 dozen
x = 20 × 7/2 /6
x = 140/2 ÷ 6
x = 140/2 × 1/6
x = 140/12 cups of flour
x = 11 8/12
= 11 2/3 cups of flour
Therefore, 11 2/3 cups of flour must be used to make 20 dozen.
