Jack is making lemonade and mixes 3 liters of sugar with 8 liters of lemon juice. Which ratio of liters of sugar to lemon juice will make the concentration of lemonade?
A: 15 to 32
B: 9 to 6
C: 12 to 32
D: 6 to 24
Answer:
C. 12 to 32
Step-by-step explanation:
The simplified ratio would be 3:8
So multiply 3*4=12
And multiply 8*4=32
12:32
The reason the other ones wouldn't work is because 3 and 8 are not multiplied by the same number
For example
A.)15 to 32 wouldn't work because there not multiplied by the same number
3*5=15
8*4=32
What is the slope-intercept equation of a line with a slope of -5 and y-intercept of 3?
y = -5x + 3
y = -5x - 3
y = 3x - 5
y = 3x + 5
Please help me. What are the answers to question one and 2. This is due at 12 tonight
Answer:
For the 1st one the answer is y = 5x + 150 and the second one is equal to y = -25x + 200.
Step-by-step explanation:
The first one would not be 30 because you're not finding the x value, just the equation. The second one you start with 200 hundred so you're adding 200 and since you're spending money every month it means subtracting. And the only equation that makes sense is y = -25x + 200

Write one example of a linear function and one example of a non-linear function in the format: y=mx +b
Answer:
Linear: 3x +9 =2x
Non Linear: x+2y=1 and x = y
Answer:
Examples, solutions, videos, and lessons to help Grade 8 students learn how to interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.
For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.

Dracula jumped 5 times every 30 minutes at that rate, how long,in minutes will it take to jump 6 times?
Answer:
36 minutes
Step-by-step explanation:
If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:
30 / 5 = 6
So, if he were to jump a sixth time:
30 + 6 = 36
Therefore, Dracula jumps 1 time per 6 minutes.

(–6,–5)

(2,–9)
(4,–10)

Answer:
Step-by-step explanation:
Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.
I'm bad at transitions so here's the math:
(y2-y1)/(x2-x1)
((-10)-(-9))/(4-2)
-1/2 ------> Thats "m".
SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE
The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.
Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.
y=mx+b
m=-1/2
b=-8
y=-1/2x+-8-----> y=-1/2x-8

Ms.Alvarez's math class surveyed 10 students in 6th grade and 10 students in 7th grade. The class asked how many hours of chores each student did the previous weekend. The results were displayed in two histograms.
Mean is greater for grade 7.
Median is greater for grade 7.
So, the correct options are B and D.
What is mean and median?"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.
The median is the middle number in a set of values when those values are arranged from smallest to largest."
Mean for grade 6 is
= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]
= [tex]\frac{10}{7}[/tex]
Mean for grade 7 is
= [tex]\frac{1+2+5+2}{4}[/tex]
= [tex]\frac{10}{4}[/tex]
From both we get, Mean is greater for grade 7
Median for grade 6 is 1
Median for grade 7 is
= [tex]\frac{2+5}{2}[/tex]
= 3.5
From both we get, Median is greater for grade 7
So, the correct options are B and D.

Don't try to cheat the system by asking so many questions in 1 block
Question 1. if 3 flowers = 4 inches, and she has a 3 foot long row to plant flowers, then we need to see how many inches the row is.
1 foot = 12 inches
12 inches x 3 = 36 inches, or 3 feet.
Now we need to divide.
36 divided by 4 = 9.
So now we know that Mrs. Ryan can plant x amount of flowers 9 times. This makes the answer easier to find.
To find the answer, we need to simply multiply 3 and 9.
3 x 9 = 27.
Your answer would be Mrs. Ryan planted 27 flowers.
Question 2. this is simple. Just multiply 5 and 3.
5 x 3 = 15.
Your answer would be Mrs. murphy bought 15 feet of fabric.
Question 3. This is simple...Just multiply 4.3 x 100, or move the decimal over to the right twice and put a 0 where theres an empty space.
4.3 x 100 = 430
Your answer is the line is 430 centimeters wide.
Question 4. This is simple, just multiply 2.9 x 100 or move the decimal over to the right twice and put a 0 where there's an empty space.
2.9 x 100 = 290
Your answer is The book is 290 milliliters wide.
Question 5. This is also very simple. This time we add a decimal twice to the left. Put the decimal next to the 0 in 210.
210.
21.0
2.10
Your answer would be the bookshelf is 2.1 meters tall.
Question 6. This is, again, simple... Just multiply 3 and 1.61.
3 x 1.61 = 4.83
Your answer would be Connor ran 4.83 kilometers.
Question 7. This is simple, again... Just multiply 13 and 2.54.
2.54 x 13 = 33.02
Your answer would be c, 33.02 cm.

20% of the students in Mrs. Sosa’s class like veggie pizza. If there are 50 students in the class, how many students like veggie pizza?
Answer:
10 students like veggie pizza
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
20% is equivalent to 0.2. If we do the math 50 x 0.2, we get 10.
Solving 50 x 0.2:
50 x 0.2 | Move the decimal right once to make a whole in 0.2, move the decimal left one (because we are doing multiplication) in 50.
5.0 x 02 | Remove any unnecessary 0s.
5 x 2 | Solve.
10 | Answer.
50 x 0.2 = 10
Melissa has $275 in her savings account. She plans to deposit $73 each month for the next 12 months. At the end of the year, she will have an account balance of $1151.

275 + 73(12) = 1151
Answer:
275 + 73(12) = 1151
