Answer:
Step-by-step explanation:
A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. Absolute value of a number on a number line is its distance from 0 on the number line .

0 The Division Property is used to create Step 4.
The Associative Property is used to create Step 1.
The Distributive Property is used to create Step 3.
The Subtraction Property is used to create Step 2.
Answer:
The Division Property is used to create Step 4.
Step-by-step explanation:
i might be incorrect, but here's the whole equation just in case:
6(3x−4)−26=40
6(3x−4)−26=40
(6)(3x)+(6)(−4)+−26=40(Distribute)
18x+−24+−26=40
(18x)+(−24+−26)=40(Combine Like Terms)
18x+−50=40
18x−50=40
18x−50+50=40+50
18x=90
18x/18 = 90/18

= -1.75
θ =
arctan( ΔY ) + 360°
ΔX

ΔX = 2 – -2 = 4
ΔY = -4 – 3 = -7
Distance (d) = √ΔX2 + ΔY2 = √65 = 8.0622577482985

When x=0, y = -0.5
When y=0, x = -0.28571428571429
which ratio is greater than 11/16
Answer:
3:4
Step-by-step explanation:
because in a simplified ratio, it tells us that in any set of whatever number (total of 3 and 4), there will be a quantity in simplification of 3 on one side.
3:4 is also a simplified ratio which can be reversed to a higher fraction than 11/16 (which would be 11:16 in ratio form fue to the inability to simplify) therefore making it a greater ratio.25x10 to the power of 6 in standard form

It takes Deanna seven hours to paint a fence. What fraction of the fence does she paint in one hour?
Answer: 1/7
Step-by-step explanation:
From the question, we are informed that it takes Deanna seven hours to paint a fence. The fraction of the fence does she paint in one hour will be one divided by seven hours which can mathematically be written as:
= 1/7
This means that she'll paint 1/7 of the fence in 1 hour.

f(x) = 2[[X-3.5]] : What is f(2)?
Answer:
f(2)= -3
Step-by-step explanation:
f(x)= 2 [x-3.5]
f(2)= 2[2-3.5] substitute all of your "x" for the number "2" f(2)=2[ -1.5] 2-3 is -1.5
f(2)= -3 2 times -1.5 is -3
The value of f(2)= -3
Calculation of the value of f(2):Since f(x) = 2[[X-3.5]
So,,
f(x)= 2 [x-3.5]
f(2)= 2[2-3.5]
f(2)=2[ -1.5]
f(2)= -3

State whether the data described below are discrete or continuous, and explain why.
The exact heights of different elephants. Choose the correct answer below.
A. The data are continuous because the data can take on any value in an interval.
B. The data are discrete because the data can only take on specific values.
C. The data are continuous because the data can only take on specific values.
D. The data are discrete because the data can take on any value in an interval.
Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

There are 130 people in a sport centre. 65 people use the gym. 51 people use the swimming pool. 44 people use the track. 15 people use the gym and the pool. 14 people use the pool and the track. 10 people use the gym and the track. 1 person uses all three facilities. A person is selected at random. What is the probability that this person uses at least 2 facilities?
Answer:
0.285
Step-by-step explanation:
Total peoples are, n=130
Number of people who use gym =65
Number of people who use swimming pool =51
Number of people who use the track =44
Number of people who use the gym and the pool =15
Number of people who use the pool and the track =14
Number of people who use the gym and the track =10
Number of people who use the gym, the pool, and the track =1
So, the number of people who use the gym and the pool =15-1=14
The number of people who use the pool and the track =14-1=13
The number of people who use the gym and the track =10-1=9
Now, the people who use at least two facilities are the people who use 2 or 3 facilities, which is 14+13+9+1=37.
So, the number of favorable outcomes =37
Total number of sample space, n=130
Hence, the probability, P, that the 1 randomly selected person uses at least 2 facilities is as follows:
[tex]P=\frac{37}{130}=0.285[/tex]

Answer:
x = [tex]\frac{-12}{37}[/tex]
or
x = [tex]-\frac{12}{37}[/tex]
Step-by-step explanation:
If you are trying to find x:
1) Go by order of operations (PEMDAS)
217 + 37(3x - 5) = - 4
217 + 111x - 185 = - 4
111x + 217 - 185 = - 4
2) We Want to get 'x' by itself:
111x + 32 = - 4
- 32 = -32
---------------------
111x = - 36
[tex]\frac{111x}{111}[/tex] = [tex]\frac{-36}{111}[/tex]
(Simplify the expression)
x = [tex]\frac{-36}{111}[/tex]
(Both the numerator and denominator can be divided by 3)
x = [tex]\frac{-12}{37}[/tex]
or
x = [tex]-\frac{12}{37}[/tex]
(Both are the same)

You are creating identical treat bags using 18 chocolate bars and 30 peanut butter cups. What is the GREATEST number of bags you can fill equally using all the treats? *You will upload a photo of your work for questions 12 and 13 at the end of the test. *
Answer:
The answer is 6.
Step-by-step explanation:
To find the greatest number of bags we can fill equally while using all the treats, we need to find the common denominators of 18 and 30.
After calculating it, we can see that if we fill six bags with both treats distributed equally, we will have used all the treats. 3 chocolate bars and 5 peanut butter cups for each bag.

Answer:
She messed up because if a bouquet costs $2.50 then 2.50 times 40 is $100 so she could have saved 20 more dollars
Answer:
Sample Response: To find the unit cost for her choice, divide $120 by 40 to get $3.00 per bouquet. This unit cost is more than the other deal.
