Answer:
The problem basically is saying that find two numbers that add up to 8, where one is three times the other.
Step-by-step explanation:
The best thing to do here is to write a simple system of equations.
b+y=8
b=3y
The first equation means that the total blue paint plus the total yellow paint is equal to 8 ounces.
The second equation means that the blue paint is equal to 3 times the yellow paint.
We can isolate b in the first equation to get b=-y+8
-y+8=3y
8=4y
y=2.
So we have that she needs two ounces of yellow paint.
Therefore she needs six ounces of blue paint.
Drag the yellow bar to 2, and the blue bar to 6.

Pete wants to treat several friends to the baseball game. he has a budget of $110. tikets are $8. he will spend $20 on parking how many friends can he afford to take without going over his budget?
Answer:
He can take 11 friends.
Step-by-step explanation:
110 - 20 = 90
Then you do simple math, how many times can 8 go into 90? Well, 8 times 10 is 80, so add 8 more and you have 88 (Which is 8 times 11).
90 - 88 = 2, so you can put in anymore.

if on a map, 1 inch = 50 miles, how many miles is 2 3/8 inches equal to?
Answer:
118 3/4 miles
Step-by-step explanation:
1 in = 50 miles
2 3/8 inch = 2 3/8 * 50
2 3/8 = 19/8
19/8 * 50/1 = 950/8 = 118 3/4

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

If m∠1 = 2x + 5 and m∠6 = x - 2
Find:
1.) The value of x with solution
2.) m∠1 =
3.) m∠2 =
4.) m∠3 =
5.) m∠4 =
6.) m∠5 =
7.) m∠6 =
8.) m∠7 =
9.) m∠8 =
Answer:
1. x = 59°
2. ∠1 = 123
3. ∠2 = 57
4. ∠3 = 57
5. ∠4 = 123
6. ∠5 = 123
7. ∠6 = 57
8. ∠7 = 57
9. ∠8 = 123
Step-by-step explanation:
∠1 = ∠4 = Vertically opp. angles = 2x + 5
∠2 = ∠3 = Vertically opp.angles
∠3 = ∠6 = Alternate interior angles
∠4 = ∠5 = Alternate interior angles
∠5 = ∠8 = Vertically opp. angles
∠6 = ∠7 = Vertically opp. angles = x - 2
Therefore,
∠1 = ∠4 = ∠5 = ∠8 = 2x + 5 ∠2 = ∠3 = ∠6 = ∠7 = x - 2
By angle sum property,
∠1 + ∠2 = 180°
2x + 5 + x - 2 = 180
3x + 3 = 180
3x = 177
x = 177 ÷ 3
x = 59
Now, 2x + 5 = 123
x - 2 = 57

You have a pizza with diameter 12
2
3 in., and a square box that is 12.65 in. across. Write 12
2
3 as a decimal. Can you fit the pizza inside the box?
What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

–18.4 = 3.2(n + 3) + 0.8
please help!!
Answer: n= -9
Step-by-step explanation:
-18.4 = 3.2(n + 3) + 0.8
-18.4 = 3.2n + 9.6 + 0.8
-18.4 = 3.2n + 10.4
-28.8 = 3.2n
-9 = n

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.
Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes

rohan cycled 30 km in 2 h.how long will he take to cycle 45 km if he continues at the same rate
Answer:
3 hours
Step-by-step explanation:
We can use ratios to solve
30 km 45 km
--------- = ---------------
2 hours x hours
Using cross products
30 * x = 2 * 45
30x = 90
Divide each side by 30
30x/30 = 90/30
x = 3
so basically you can just tell me where the boxes go and bam you get 20 points
