Answer:
m= -4.5
Step-by-step explanation:
Let's solve your equation step-by-step.
6m−3=5−(m+39.5)
Step 1: Simplify both sides of the equation.
6m−3=5−(m+39.5)
6m−3=5+−1(m+39.5)(Distribute the Negative Sign)
6m−3=5+−1m+(−1)(39.5)
6m−3=5+−m+−39.5
6m+−3=5+−m+−39.5
6m−3=(−m)+(5+−39.5)(Combine Like Terms)
6m−3=−m+−34.5
6m−3=−m−34.5
Step 2: Add m to both sides.
6m−3+m=−m−34.5+m
7m−3=−34.5
Step 3: Add 3 to both sides.
7m−3+3=−34.5+3
7m=−31.5
Step 4: Divide both sides by 7.
7m
7
=
−31.5

m=−4.5
Step-by-step explanation:
6m-m=5-3+39.5
5m=-37.5
m=7.5

If p varies inversely as Q2 and p = 4 when Q =0.5, find p when Q = 1.5
Answer:
a) k = 8
b) p = 12
Step-by-step explanation:
Step(i):-
Given that p varies inversely as Q
p∝ Q
p = k Q
Given that p = 4 and Q = 0.5
4 = k (0.5)
k = [tex]\frac{4}{0.5} = 8[/tex]
Step(ii):-
Given that Q = 1.5
p = k Q
p = 8 (1.5)
p = 12

Which gives 28 + 24 as a product of the GCF and a sum?
a. 2 (14 + 12)
b. 4 (7 + 6)
c. 2 (26 + 22)
d. 40 + 12
Answer:
b. 4 (7 + 6)
Step-by-step explanation:
Finding the GCF between 28 and 24:
We keep dividing while both numbers can be divided by the same factor. So
28 - 24|2
14 - 12|2
7 - 6
There is no number for which 7 and 6 are both divisible by, so the GCF between 28 and 24 is 4.
Simplifying in function of the GCF:
Now, we put 4 in evidence, and divide the rest of the expression by 4. So
[tex]28 + 24 = 4(\frac{28}{4} + \frac{24}{4}) = 4(7 + 6)[/tex]
The answer is given by option b.

Nolan says the rate of change shown on the graph is 2/3
Nadia says the rate of change shown on the graph is 8/3
A. Nolan
B. Nadia
Why did you put that answer?
Answer:
Nadia is correct
Step-by-step explanation:
Rate of change = y/x
Using a point on the graph, say, (3, 8),
Rate of change = 8/3.
Therefore, Nadia's answer is correct while that of Nolan is wrong.
Mary is cutting strips of paper for a craft project. Each strip is 1/6 of a sheet of paper. Mary has 2/3 of a sheet of paper left to cut. She wants to determine how many more strips of paper she can cut from what is left.
Mary can cut ___ more strips than paper
Answer:
4 more strips
Step-by-step explanation:
Given that:
Length per strip = 1/6
Fraction of paper left = 2/3
Number of strips that can be cut from the Fraction left ;
Fraction left ÷ length per strip
2/3 ÷ 1/6
2/3 * 6/ 1
(2 * 6) / (3 * 1)
12 / 3

Answer:
r = -6/15 is your answer.
Step-by-step explanation:
What yoy want to do is get r by itself.
3(2 + 5r) = You will times 3 by 2 and 5r to get
6 + 15r = You will then subtract 6 from both sides
15r = -6 You will then divide 15 by both sides to get
r = -6/15 is your answer.

Answer:
72 cm³ (see below)
Step-by-step explanation:
First, refer to the volume formula:
V = l · w · h
If you plug in all of your values and simplify, you'll get the volume:
l = 6 cm
w = 3 cm
h = 4 cm
V = (6) (3) (4)
V = 18 (4)
V = 72 cm³
Because this is volume, the measurements are units cubed, meaning it's cm³.

A local arts council has 200 members. The council president wanted to estimate the percent of its members who have had experience in writing grants. The president randomly selected 30 members and surveyed the selected members on their grant-writing experience. Of the 30 selected members, 12 indicated that they did have the experience. Have the conditions for inference with a one-sample z -interval been met
Answer:
Yes the sample can be use to make inference
Step-by-step explanation:
The inference is possible if the conditions:
p*n > 10 and q*n > 10
where p and q are the proportion probability of success and q = 1 - p
n is sample size
Then p = 12 / 30 = 0,4 q = 1 - 0,4 q = 0,6
And p*n = 0,4 * 30 = 12 12 > 10
And q*n = 0,6 * 30 = 18 18 > 10
Therefore with that sample the conditions to approximate the binomial distribution to a Normal distribution are met
To check the condition for inference with a one sample z-interval, we have to divide randomly selected member by total number of arts council.
No, the sample size is not less than 10% of the population size,
Given:
The total number of council member are 200.
The randomly selected members are 30 .
Calculate the ratio of randomly selected members and total number of council member.
[tex]\dfrac{n}{N}=\dfrac{30}{200}\\\dfrac{n}{N}=0.15\\\dfrac{n}{N}=0.15>0.10[/tex]
Thus, No, the sample size is not less than 10% of the population size.

Answer:
Step-by-step explanation:
It is a vertical parabola. The equation of a vertical parabola can be written in the form y = a(x-h)² + k, where a>0 and (h,k) is the vertex.
You can eliminate G and I because the leading coefficient is negative.
The graph isn't marked with units, but both F and H say that the vertex is at (0,-2), so you know that each square on the graph is one unit.
Now look for another clue.
The x-intercepts are at (-1,0) and (1,0). Plug one of the points into F and H.
F: 0 = 2·1² - 2
H: 0 ≠ 1² - 2
So, F represents the graph.
