Hannah's hair was 18 inches long .Three years later it was 33 inches long. What was the percent increase,to the nearest hundredth, of Hannah's hair length?
Answer:
54%
Step-by-step explanation:
if you take 18 and divide it by 33 you would get 54
The 83.33 percent increase in Hannah's hair length.
What is the meaning of percentage?A percentage is a number or ratio expressed as a fraction of 100.
Hannah's hair was 18 inches long
After three years,
it was 33 inches long
[tex]Difference\ (increase\ in\ length) = 33-18=15\ inches[/tex]
[tex]percent\ increase = \dfrac{Increase}{Original\ Number}\times100=\dfrac{15}{18}\times100=83.3333\\\\percent\ increase = 83.33 (nearest\ hundredth)[/tex]
Hence 83.33 % increase in Hannah's hair length after three years.

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
(2x+18)°
55°
(4x+11)°
Answer:
(2x+18) degrees
Step-by-step explanation:
A triangle is a total of 180 degrees, so you would do:
(2x+18)+55+(4x+11)=180
(2x+4x)+(18+55+11)=180 <- take out parentheses and add like terms
6x+84=180 <- subtract 84 from both sides of the equation
6x=96 <- divide 6 from each side
x=16
Now that you know what x is you would plug it into each of the angles
Angle 1: 2x+18 --> 2(16)+18= 32+18= 50
Angle 2: 55
Angle 3: 4x+11 --> 4(16)+18= 64+18= 82
Then out of these three angles of the triangle, angle 1 (2x+18) would be the smallest.

7x+9=2x+39 i need all the steps
Answer:
Step-by-step explanation:
7x+9=2x+39
7x+9-9=2x+39-9
7x=2x+30
7x-2x=2x+30-2x
5x=30
5x/5=x
30/5=6
x=6
Answer:
X=6
Step-by-step explanation:
7x+9=2x+39
First, subtract 9 from both sides like this
7x+9 -9 =2x+39-9
equaling 7x=2x+30
Then, subtract 2 from both sides like this
7x - 2=2x -2+30
equaling 5x=30
Lastly you divide 5 from both sides like this
5x / 5 = 30 / 5
equaling x=6

#10 and 11
Questions are in the Picture
Answer:
Step-by-step explanation:
For problem 10:
1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)
2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)
3. 9/x=(9+6)/10 (Substitute the given values into this equation)
4. x=6 (Use algebra to solve for x)
For problem 11:
1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)
2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)
3. 14/(14+7)=18/(18+x) (Substitute given values)
4. x=9 (Solve for x)

-a table costs $40.00 a day to rent
-shari plans to sell each pie for $8.50
-each pie costs her $2.00
how much profit will shari earn if she sells 75 pies per day
Answer:
She will earn $517.5 in profit and will pay $120 for 3 days in rent of the table, and each pie will gain her $6.50 profit.
Explanation:
8.5*75= 637.5
63.5-120= 517.5

Which of these systems of equations would be best solved using the subtraction method?
I. 2x−7y+3y = 4 −6x−4y = −52
II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52
Answer:

1. x+2y=6 or x=6-2y
3x-2y=2
3(6-2y)-2y=2
18-6y-2y=2
18-8y=2
-8y=-18+2
-8y=-16
y=-16/-8
y=2 ans.
x+2*2=6
x+4=6
x=6-4=2 ans.
Proof:
3*2-2*2=2
6-4=2
2=2

One market sells a 3-kilogram bag of tortillas for 45 pesos, and the second market sells 2 kilograms of tortillas for 22 pesos.
Which unit price is lower? / Would I subtract 2 kilo from 22 pesos?
Answer:
The second market is cheaper
Step-by-step explanation:
For the first market:
If the 3Kg = 45 pesos
then 1Kg = 15 pesos because you divide it by 3
In the same way for the second market:
2Kg = 22pesos
so 1Kg is 11 pesos as you divide it by 2.
Therefore the second market is cheaper as the unit price is lower.

Dr. Wong has a table of data in her veterinary office that shows the average lifespans and weights of several popular dog breeds. Alfonso made a scatterplot of these data for a math project.
Answer the questions to make predictions about the lifespan of a specific breed of dog.
1. Describe the association shown by this scatterplot.
2. Alfonso is thinking of getting a bloodhound. Bloodhounds usually weigh about 90 pounds. Based on the data, estimate for the lifespan of a bloodhound. Explain how you made your estimate.
3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:
1. Alfonso didn't use a good estimation method,
2. Dani doesn't remember Ol' Sniffy's age correctly, or,
3. Ol' Sniffy lived an unusually long time?
Justify your answer.
Answer:
1. The heavier the dogs are, the shorter lifespan they have.
2. The lifespan of a bloodhound is on average 10 years long
3. Number 2
Step-by-step explanation:
#1 explination: Since its obvious that the graph angles downwards as it goes towards the left, and because as you go to the left you get heavier dogs, put 2 and 2 together and you get my answer.
#2 explination: We see 3 dots around 90 pounds, one that lives 11 years, and 2 that live 10 years. Since we need to be accurate, we need to find the average of 10, 11, and 10. (10+10+11)/3=10.33. Now we round to 10, so 10 is our answer.
#3 explination: Since there is a bloodhound that lives to be 14, we have two answers, 2 or 3. 1 doesn't work since if Alfonso doesn't have good estimation, the first two questions wouldn't matter *the more you know*. Since we see no unusual pattern between any of the three dots I mentioned earlier, Dani must of forgotten her dog's age (probably because of that dog years thing.)

Sumalee won 40 super bouncy balls playing horseshoes at her school's game
night. Later, she gave two to each of her friends. She only has 8 remaining.
Choose the correct equation below to represent the situation?
a. 2x-8=40
b. 40-2x-8
c. 8-2x=40
d. 40-2x=8
let x represent how many friends Sumalee has.
40-2(x)=8

Write an equation for the relationship shown in the table.
Answer:
(0.3/1)x-1.7
Step-by-step explanation:
I used the format mx+b
m= slope
x= x value (usually stays as x when you write an equation and replace it with the x value when solving)
b= y-intercept (in this case when p is zero what is the q value)
y-intercept = -1.7 (in this equation found from the table)
slope= 0.3/1 (the rate it the numbers increase at. q is changing +0.3 each time and p is changing by 1. p (or the x value) goes on top of q (or the y value)) (I found the missing information in between 2 and 5)
hence you have (0.3/1)x-1.7
Answer:
its (0.3/1)x-1.7
