The population of a city was 60,000 in 2015. In 2016, the population of the city was 63,000. The percent increase in the population from 2015 to 2016 was the same as it was from 2016 to 2017. What was the population of the city in 2017?
Answers
The answer of this question is 66,000.
When you do the formula to find the percent increase the higher amount minus the lower amount, divided by the old population is how you find the percent increase, thus there is a five percent increase. So 5 percent of 63000 is 63000 times .05 which is 3150 and 3150 plus 63000 is 66150

In between two primary markings are 4 secondary markings. The box extends from 1 to 6 on the number line. There is a vertical line at 3.5. The whiskers end at 0 and 8. Above the plot is written Duration of Participation. Below the plot is written Years. At least how many schools have participated for more than 1 year and less than 3.5 years? (1 point) 3 6 10 11
Answers
Answer:
20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

Cross multiply would take longer time, but if you wish you could use both ways to check your answer.
I will be turn into decimal:
Main Fraction: 9/15 ⇒ 0.6
3/10 ⇒ 0.3
36/60 ⇒ 0.6

First Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 2.
Second Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 1/3.
Please help! If you help with this please do my other questions!! (They are very similar!)
Answers
Answer: See in the explanation, screenshot attached
Step-by-step explanation:
SQUARE QRTS
Step 1: Label all of the coordinates
Step 2: Find the coordinates of the points
Q: (-2, 1)
R: (2, 1)
T: (-2, -2)
S: (2, -2)
Step 3: Know what it means to dilate
To dilate is to make a shape bigger or smaller. For example, when it says to dilate by a scale factor of 2, you multiply each coordinate by 2 to get coordinate pairs that are twice the original amount (in this case you make it bigger). However, if it says to dilate by a scale factor of a fraction, for example 1/2, you'd multiply the coordinates by 1/2 and hence make it smaller (1/2 its size).
Step 4: Dilate by a scale factor of 2--multiply by 2
*x stands for the x coordinate, and y stands for the y coordinate*
Q: -2, 1
x: -2x2= -4
y: 1x2= 2
[Dilated] Q: -4, 2
R: 2, 1
x :2x2= 4
y: 1x2= 2
[Dilated] R: 4, 2
T: -2, -2
x: -2x2= -4
y: -2x2=-4
[Dilated] T: -4, -4
S: 2, -2
x: 2x2= 4
y: -2x2= -4
[Dilated] S: 4, -4
Step 5: Plot the new pairs
(See screenshot)
SQUARE ABCD
Step 1: Label all the coordinates
Step 2: Find the coordinate pairs of the points
A: -3, 3
B: 3, 3
C: 3, -3
D: -3, -3
Step 3: Remember what it means to dilate
(See 1st explanation)
Step 4: Dilate by a scale factor of 1/3
**Since 1/3 is a fraction, we are making the square smaller, or making it ⅓ of its original size. You will see that the numbers of the coordinates get smaller once you dilate them.**
A: -3, 3
x: -3x1/3= -1
y: 3x1/3= 1
[Dilated] A: -1, 1
B: 3, 3
x: 3x1/3 = 1
y: 3x1/3= 1
[Dilated] B; 1, 1
C: 3, -3
x: 3x1/3= 1
y: -3x1/3= -1
[Dilated] C: 1, -1
D: -3, -3
x: -3x1/3= -1
y: -3x1/3= -1
[Dilated] D: -1, -1
Step 5: Plot the new pairs

Mr. Jackson is ordering kazoos for his second, third, and fourth grade music classes.
The kazoos come in boxes of 8. There are 26 second graders, 24 third graders, and 30 fourth graders.
How many boxes of kazoos does Mr. Jackson need to order so that every student will receive a kazoo?
Enter your answer in the box.
Answers
Answer:
The boxes of kazoos Mr. Jackson needs to order (26 + 24 + 30) ÷ 8.
We have given that,
There are 26-second graders, 24 third graders, and 30 fourth graders.
What is the expression?
An expression, in math, is a sentence with a minimum of two numbers and at least one math operation contain in it.
The amount of kazoos needed is 1 for every student
26 + 24 + 30
Since 8 come in each box, you divide by 8
To get your answer of (26 + 24 + 30) ÷ 8.
You have to add 24 with 26 with 30 then divide that by 8 and which will get you ten. Ten is how many packages you Mr. Jackson would need for his 2nd, 3rd, and 4th grade classes
Please help i give brainliest, show the work though. Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.
Answers
Answer: 5 1/2 pies as a mixed number, 11/2 as an improper fraction, 5.5 as a decimal, 550 as a percent
Step-by-step explanation:
2x5+1 11
-----------= -----
2 2
The fraction 5 1/2 is equal to 5, plus 1 divided by 2 which is equal to 5, plus 0.5 which is equal to 5.5 in decimal
5.5 x 100 = 550 percent
Given statement: Susan is buying 5 and a half pies from the market.
We already know:
The word "and" means "in addition to", which means addition (+)Therefore, the number of pies Susan bought is;
⇒ 5 and a half pies⇒ 5 + half pies∴ Half can be written as ½
⇒ 5 + ½If a whole number is being added to a fraction, we can combine them to convert the sum into mixed fraction.
⇒ 5 + ½⇒ 5 ½Therefore, 5 ½ is the fraction of pies, Susan bought.
Improper fraction:Given statement: Susan is buying 5 and a half pies from the market.
In mixed fraction: Susan is buying 5 ½ pies from the market.
To convert the mixed fraction of pies into improper fraction, simply multiply the whole number by the denominator and add the numerator to the product of the whole number and the denominator. The denominator in the mixed fraction will remain the same in the denominator.
⇒ 5 ½⇒ [(5 × 2) + 1]/2⇒ [(10) + 1]/2⇒ [11]/2 = 11/2Therefore, 11/2 is the fraction of pies, Susan bought.
Decimal:Given statement: Susan is buying 5 and a half pies from the market.
In improper fraction: Susan is buying 11/2 pies from the market.
Clearly, we can rewrite 11/2 as;
⇒ 10/2 + 1/210/2 results in getting 5 and 1/2 results in getting 0.5. Therefore,
⇒ 5 + 0.5⇒ 5.5Therefore, 5.5 is the decimal of pies, Susan bought.
Percent:Given statement: Susan is buying 5 and a half pies from the market.
In decimal: Susan is buying 5.5 pies from the market.
Simply multiply the decimal by 100 to determine the percentage of pies bought by Susan.
⇒ 5.5 pies = 5.5 x 100% = 550%
Therefore, 550% is the percent of pies, Susan bought.

A parallelogram has an area of 120 square feet and a height of 6 feet.
What is the length of the base of the parallelogram?
Enter your answer in the box.
*box*
Answers
Answer:
20 feet
Step-by-step explanation:
1. We know from here that A = bh (Area = Base x Height).
We are given:
A = 120 ft^2
h = 6 ft
b = ?
2. Let's rearrange our formula (A = bh) so that we find what "b" equals."
Our new formula will be: b = A/h (base = Area / height).
3. Let's apply it to the question and do the required math!
b = A/h
b = 120/6
b = 20 ft
Answer:
b = 20 ft
Step-by-step explanation:
The area of a parallelogram is given by:
A = b*h
where,
A: area = 120 ft^2
b: base = ?
h: height = 6 ft
From the equation for A, solve for b, replace the values of A and h and simplify:
b = A/h
b = 120ft^2/6ft
b = 20ft
Hence, the length of the base of the parallelogram is 20 ft

e=\frac{4}{3}, r \cos \theta=-3
Answers
The polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]
What is the polar equation?A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as
[tex]r =\dfrac{e\times c}{1+ecos\theta}[/tex]
[tex]r =\dfrac{1\times 4}{1+1\times cos\theta}[/tex]
[tex]r=\dfrac{4}{1+cos\theta}[/tex]
