Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1
Answer:
-1 < -0.25
Step-by-step explanation:
-1 is less than -0.25
less than symbol = <
greater than symbol = >
Example; -1 > -2 --- negative one is greater than negative two OR -2 < -1 --- negative two is less than negative one
Answer:
-1<-0.25
Step-by-step explanation:
3.3 + 10m = 7.81 find the value of m ill give brainliest
Answer:
m = .451
Step-by-step explanation:
3.3 + 10m = 7.81
Subtract 3.3 from each side
3.3-3.3 + 10m = 7.81-3.3
10 m =4.51
Divide each side by 10
10m/10 = 4.51/10
m = .451
Answer:
0.451
Step-by-step explanation:
3.3+10m=7.81
10m = 7.81-3.3
10m = 4.51
m = 4.51/10
m = 0.451

(4b^2+3)(4b^2-3)
Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
[tex]16b^4-9[/tex]
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For [tex](t_1+t_2)(t_3+t_4)[/tex], let:
[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]
In the FOIL method, the steps go:
[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]
Given [tex](4b^2+3)(4b^2-3)[/tex], we have:
[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]
Combine like terms:
[tex]\boxed{16b^4-9}[/tex]
The prices for 7 different totes are $52,$22, $50, $44, $60, $48, and $52. What is the outlier in the data set?
Answer:
$22

An outlier in a data set is the one farthest from the other data points. 22 is far away from the other points, so that is the outlier.
Answer:
22
Step-by-step explanation:
It is farther off than from all of the rest of the #'s.
If a Car can drive 35 miles on 7 gallons of gas, how many miles can it travel on 2 gallons of gas (assuming miles per gallon is proportional)? Give and explain your answer.
Answer:
10 miles
Step-by-step explanation:
35/7 is 5 so therefore if you do 5+5+5+5+5+5+5 is 35
so that means 2 gallons which is 10

9 hundreds = _____ tens
Answer:
90
Step-by-step explanation:
900 in groups of 10 would need 90 groups to equal 900.
Answer:
90
Step-by-step explanation:
We also have 9 tens, which means we can say 9×10=90. And we have 24 ones, which means we can say 24×1=24.
You are renting a car that charges a $30 fee plus 40 cents a mile. The rate of change is $30.
True or False?
Hi there!
»»————- ★ ————-««
I believe your answer is:
False.
0.40 is the rate of change.
»»————- ★ ————-««
Here’s why:
As mentioned in the scenario, the car company charges a $30 fee which is flat. The '30' is the base for the total cost. The car company also charges 40 cents for every mile driven. This means that the company would charge a 40 cents for a mile driven. 40 cents would be the rate of change, not $30.⸻⸻⸻⸻
Side Note:
An equation that represents the situation could be:
[tex]C = 0.40m + 30[/tex]
'C' is the total cost for renting the car.
'm' is the number of miles the car is driven.
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Find the missing dimensions
Answer:
short base: 6 yards
long base: 8 yards
Step-by-step explanation:
Our understanding of your figure is shown below.
The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."
The short base is 6 yards.
__
The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.
The long base is 8 yards.
Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.
What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12

the width w of a rectangular swimming pool is x+5 the area a of the pool is x^2+4-5
what is an expression for the length of the pool? step by step
Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1
Answer:
x-1

help pleaseeee. this is due in an 10 minutes
Answer:
(you'll have to read the explanation)
Step-by-step explanation:
There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!
Answer: See the attached image below
1 1/2 is located at the exact midpoint between 1 and 2.
2 1/4 is located 2 tickmarks to the right of 2.
===================================================
Explanation:
Think of 1/2 as 4/8
The number 1 1/2 is the same as 1 4/8
So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).
This places us exactly at the midpoint between 1 and 2.
-----------------
To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8
We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8
