3) There are 35 people living in poverty and 42 people not living in poverty
1) John says that the ratio of people living in poverty to the people not living in poverty is 5:7. Explain why John is or is not correct. Use a diagram to support your answer.
Answer:
John is not correct
Step-by-step explanation:
(Unless you meant 5:6)
Make the base question into [tex]\frac{35}{42}[/tex]
simplify as much as possible. I found the Greatest Common Denominator (GCF) of 35 and 42, which was 7
divide 35 and 42 by the GCF (7), and you should get 5:6 as your answer.

Show all work to multiply quantity 3 plus the square root of negative 16 end quantity times quantity 6 minus the square root of negative 64 end quantity
Plus means addition and square root means √
3 plus the square root of negative 16: 3 + √-16
Minus means subtraction and square root means √
6 minus the square root of negative 64: 6 - √-64
Its asking you to multiply both quantities.
(3 + √-16) * (6 - √-64)
Best of Luck!
Answer:
18-32i^2
Step-by-step explanation:
3 + the negative square root of 16 would simplify to 4i
so it will be (3+4i)
6 - the negative square root of 64 would simplify into 8i
so it will be (6-8i)
To solve (3+4i)(6-8i) use FOIL and add like terms

2) 23 and 24 are complementary angles. If m 23 = (x + 24)º and m 24 = (x )º, then
find the measures of these angles,
Answer:
m<23 = 57° & m<24= 33°
Step-by-step explanation:
You have to create an equation that equals 90°.
(x+24)+x=90
2x+24=90
2x=66
x=33
m<23 = 33+24= 57° so m<23= 57°
m<24= 33°

In each sack, there are 10 bags. In each bag, there are 5 pouches. Which number completes the equation that relates p, the number of pouches, and s, the number of sacks?
Answer: p = 50 s
Step-by-step explanation:
Given: In each sack, there are 10 bags. In each bag, there are 5 pouches.
i.e. Total pouches in each sack = (Number of bags in each sack) x (Number of pouches in each each bag)
= 10 x 10 =50
Let p = number of pouches, and s= the number of sacks
Then, Number of p pouches in s sacks will be given by-
p = 50 s , which is the required equation.

Answer:
put ur protactor from the middle to where its up to then look at where the line is and you will get your answer
Answer:
Step-by-step explanation:
1. PQR is an equilateral triangle formed by 3 diagonals of the cube. Therefore, it would be 60 degrees. 2. An angle which measures less than 90° is called an acute angle. The measure between 0° to 90°. In the picture below, the angle formed by the intersection of PQ and QR at Q forms an angle PQR which measures 45°. Thus, PQR is called an acute angle.
14x-10=3 (4+x); solve for x
Answer:
x = 2
Step-by-step explanation:
So we are given the equation 14x - 10 = 3(4 + x) and we are asked to solve for x. To this, we will have to get x by itself on one side and a value on the other side.
14x - 10 = 3(4 + x)
Distribute the 3 on the right side.
14x - 10 = 12 + 3x
Add 10 to both sides.
14x = 22 + 3x
Subtract 3x from both sides.
11x = 22
Divide both sides by 11.
x = 2
So now we got the answer of x = 2.
I hope you find my answer helpful.
Answer:
x = 2
Step-by-step explanation:
14x - 10 = 3(4+x)
=> 14x -10 = 12 + 3x
=> 14x - 3x = 12 + 10
=> 11x = 22
=> x = 22/11
=> x = 2

The value of x in the given expression is -a/6
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 4 = 6x / a + 5
Solving for x, we get,
4 = 6x / a + 5
Subtracting 5 both the side,
6x / a = -1
Multiplying by a both the sides,
6x = -a
Dividing by 6 both sides,
x = -a/6
Hence, the value of x is -a/6

What is depreciation?The monetary value of an asset decreases over time due to use, wear and tear or obsolescence. This decrease is measured as depreciation.
What is compound interest for depreciation?If the reduced value of the goods is compounded for fixed time then it is called compound depreciation.
Formula of compound interest for depreciation:
[tex]A = P(1-\frac{r}{100} )^{n}[/tex]
Where,
A= Final Amount
P = initial Principal
n = time in years
r = rate per annum
According to the question
New copier costs (p) = $10,000
depreciates in value every year (r) = 15%
The principal will replace the copier when it drops below 10% of its original value.
i.e Final amount should be less than [tex]$10,000 * \frac{10}{100}[/tex]
A is < $ 1000
Using compound interest formula :
[tex]A = P(1-\frac{r}{100} )^{n}[/tex]
[tex]1000 > 10000(1-\frac{15}{100} )^{n}[/tex]
[tex]0.1 > (0.85 )^{n}[/tex]
n ≈ 14.168
n = after 15years (next whole no)
Hence , The solution set for the inequality is (15, ∞).

Write the sentence as an inequality. Three times a number r plus 8 is fewer than −12
Answer: [tex]3r+8<-12[/tex].
Step-by-step explanation:
It is given that three times a number r plus 8 is fewer than −12.
We need to write the sentence as an inequality.
Three times a number r = 3r
Times a number r plus 8 = 3r+8
Fewer than = less than = <
So, the inequality for the sentence "three times a number r plus 8 is fewer than −12" is
[tex]3r+8<-12[/tex]
Therefore, the required inequality is [tex]3r+8<-12[/tex].
The inequality that describes the sentence is:
[tex]3r + 8 < -12[/tex]
--------------------------------
3 times 1 is [tex]3 \times 1 = 3[/tex], 3 times 2 is [tex]3 \times 2 = 6[/tex], and so on, thus 3 times a number r is [tex]3 \times r = 3r[/tex].The plus word means that we have an addition operation, plus 8, thus [tex]3r + 8[/tex]Fewer than -12 means that the less than -12 completes the inequality, thus:[tex]3r + 8 < -12[/tex]
Which is the inequality that describes this situation.
