Olivia has eight envelopes labeled “x” and an additional $218, and Jasmine has five envelopes labeled “x” and an additional $521. Each envelope has the same amount of money in it. How much money must be in each envelope for them to have the same amount of money? Write and solve an equation. Solve each of the following inequalities for the given variable. Represent your solutions algebraically and on a number line. Be sure to use a test point to check your solution region.
Answer:
The envelopes have to have $101 for them to have the same amount of money.
x=$101
Step-by-step explanation:
Olivia has eight envelopes labeled “x” and an additional $218, so we can write that she has this amount of money:
[tex]M_o=8x+218[/tex]
Jasmine has five envelopes labeled “x” and an additional $521. We can write the money that Jasmine has as:
[tex]M_j=5x+521[/tex]
If both have the same amount of money, we have:
[tex]M_o=M_j\\\\8x+218=5x+521\\\\8x-5x=521-218\\\\3x=303\\\\x=303/3=101[/tex]
The envelopes have to have $101 for them to have the same amount of money.
Answer
The envelopes have to have $101 for them to have the same amount of money.

The fuel tank in a car holds 20 gallons of gasoline. The car has a fuel efficiency rating of 24 miles per gallon. If the gas tank is full when the family begins, and their destination is 1,600 miles away, what is the least number of times they will have to stop and fill the gas tank to get to their destination?
Answer:
3
Step-by-step explanation:
1600 miles × (1 gallon / 24 miles) = 66⅔ gallons
66⅔ gallons × (1 tank / 20 gallons) = 3⅓ tanks
Rounding up to the nearest integer, the family will need 4 tanks. Since they start with a full tank, they will need to stop at least 3 times.

Using tan(A+B), find the exact value of tan(105).
Answer:
-2-√3
Step-by-step explanation:
The sum of angles formula for tangent is ...
tan(A+B) = (tan(A) +tan(B))/(1 -tan(A)tan(B))
For the desired angle, we can use A=45°, B=60°. Then we have ...
tan(105°) = (tan(45°) +tan(60°))/(1 -tan(45°)tan(60°))
The tangent values we need are ...
tan(45°) = 1
tan(60°) = √3
Then our tangent is ...
tan(105°) = (1 +√3)/(1 -1·√3) = (1 +√3)²/((1 -√3)(1 +√3)) = (4+2√3)/(-2)
tan(105°) = -(2+√3)

Answer:
Point C' coincides with point E.
point D' coincides with point F.
Step-by-step explanation:
Find the value of angle O in triangle ΔBOC where O is the center of the hexagon. Once you find it, devide it by the total value of counterclockwise rotation (240°) to find how many times the point labaled C moves to the left. The value of angle O in triangle ΔCOD is the same as the value of angle O in triangl we ΔBOC, so the amount that point D moves to the left is the same.
How would you write "4/1000" In decimal form?
Answer:
0.004
Step-by-step explanation:
Since 4/10 is 0.4 and 4/100 is 0.04, 4/1000 must be 0.004
Answer:
0.004
Step-by-step explanation:
[tex]\frac{4}{1000}[/tex] is basically [tex]4 \cdot 10^{-4[/tex] (if you've learned scientific notation), so all you have to do is move the decimal to the left four times. That gives us
[tex]4.0\\0.4\\0.04\\\boxed{0.004}[/tex]
More depth:
[tex]10^{-4[/tex] also equals 0.001, so [tex]4 \cdot 0.001 = \boxed{0.004.}[/tex]

The ratio of the number of student in mr. Moore’s class compared to the number of student in miss Henry’s class is 5:4. The ratio of the number students in miss Henry’s class compared to the number of students on mr. Wilson’s class is 8:9. What is the ratio of number of students in mr. Moore’s class to mr. Wilson’s class?
Answer:
10:9
Step-by-step explanation:
First ratio is 5:4. 4 is equal to Henry class
If you múltiply the ratio by 2 you get
10:8, This ratio can be compared because now Henry class has 8
2(5:4)
10:8
8:9
Meaning that the answer is 10:9
The require ratio of number of students in Mr. Moore's class to Mr. Wilson's class is 10:9
What is Ratio?The ratio can be expression as how many times one number contain another number.
For example, If any bag contain 4 apples and 8 oranges then the ratio of apple to orange is 4:8 while the ratio of the orange to the apple is 8:2
How to find ratio?Consider M denote the number student present in the Mr. Moore's class
similarly H denote the number of student in miss Henry's class and W denote the number of student present in Mr. Wilson's class
then we have given that
M : H = 5 : 4 or
[tex]\frac{M}{H} = \frac{5}{4}[/tex]
Also we have H : W = 8 : 9
[tex]\frac{H}{W} = \frac{8}{9}[/tex]
Now multiply these two equations we have
[tex]\frac{M}{H}\times \frac{H}{W}=\frac{5}{4}\times\frac{8}{9}[/tex]
[tex]\frac{M}{W}= \frac{10}{9}[/tex]
The ratio of number of student in Mr. Moore's class to Mr. Wilson's class is 10:9
This is the conclusion to the answer.

Cutting the rectangular prism diagonally will result in the creation of two triangular prisms taking the two dimensional shape of a rectangle as its cross section.
Diagonal cutting means cutting that passes from the top edge of cuboid to edge on the bottom on opposite sides. This way, a rectangular two dimensional shaped cross section is formed

What the the Quotient 7/12 divided by 2/5
Answer:35/24
Step-by-step explanation:
7/12 ➗ 2/5
Next step we change divide sign to multiplication,with the numerator and denominator of the right hand fraction inverted
7/12 x 5/2
(7x5)/(12x2)
35/24
The quotient of 7/12 divided by 2/5 is 35/24.
To divide fractions, you need to multiply the first fraction by the reciprocal (or the multiplicative inverse) of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to find the quotient of 7/12 divided by 2/5, you multiply 7/12 by the reciprocal of 2/5, which is 5/2.
Here are the steps:
Write down the first fraction: 7/12
Write down the reciprocal of the second fraction: 5/2
Multiply the first fraction by the reciprocal: (7/12) x (5/2)
Multiply the numerators: 7 x 5 = 35
Multiply the denominators: 12 x 2 = 24
Simplify the fraction, if possible: 35/24
Therefore, the quotient of 7/12 divided by 2/5 is 35/24.

Answer:
The mean cholesterol levels
= 173873.7
Step-by-step explanation:
For The mean
The mean is going to be sum of the numbers divide by the number
Mean = (130130 +145145+ 215215 +170170+ 165165 +225225+ 240240 +185185+ 130130 +132132 )/10

Answer:
D. 96
F. 32
Step-by-step explanation:
The inequality 3x ≥ 96, means that x and 3 must be multiplied to get a product that is greater than 96. So to figure this out, you must plug in the numbers given for x, like so:
3x ≥ 96
A. 3(31) ≥ 96
93 ≥ 96 This is incorrect since 93 is not greater than 96
A tip that makes this easier is that, you can see that 31 multiplied by 3 is 93, which is only a couple numbers off 96, so all numbers after 31 will result in a product greater than 96. For example:
D. 3(96) ≥ 96
288 ≥ 96 This inequality is correct
F. 3(32) ≥ 96
96 ≥ 96
The inequality sign states that the number must be either greater or equal to 96, which it is.

A European swallow flies about 12 meters in 1 second.
How many kilometers could it fly in 15 minutes?
It could fly |
Answer:
It could fly 10,8 kilometers.
Step-by-step explanation:
The European swallow fly speed is 12 meters per second.
We have to calculate how many kilometers it could fly in 15 minutes.
This can be calculated using the equivalent factors for each of the units:
- 1 km is equivalent to 1,000 meters.
- 1 minute is equivalent to 60 seconds.
We know that the distance travelled by the fly is the product of the speed and the time, so we have:
[tex]D=v\cdot t\\\\\\D=12\,\dfrac{m}{s}\cdot15\, min\\\\\\D=12\,\dfrac{m}{s}\cdot(\dfrac{1\,km}{1,000\,m})\cdot15\, min\cdot (\dfrac{60\,s}{1\,min})\\\\\\D=\dfrac{12\cdot 15\cdot 60}{1,000}\,km=\dfrac{10,800}{1,000}\,km\\\\\\D=10,8 \,km[/tex]

Step-by-step explanation:
First triangle :
tanΦ=v/3√3
tan30=v/3√3
(√3)/3=v/(3√3)
Cross multiply
(√3)/3 x 3√3=v
(√3 x 3√3)/3=v
(3√9)/3=v
(3x3)/3=v
9/3=v
3=v
v=3
Sin30=v/u
0.5=3/u
Cross multiply
0.5xu=3
0.5u=3
Divide both sides by 0.5
0.5u/0.5=3/0.5
u=6

It took an ice cream 28 minutes to drive through one neighborhood. The truck stopped driving through the neighborhood at 2:05 pm When did the truck start driving through the neighborhood? Choose 1 answer:
Answer:
Starting time: 1:37
Step-by-step explanation:
Instead of proof to solve the problem, let us prove that the starting time above is correct;
1. There are 60 minutes in an hour, so 60 - 37 = the minutes 'till 2:00, or 23 minutes
2. Knowing that the time the truck stopped driving through the neighborhood was 5 minutes past 2:00, the minute difference being 23 + 5, or 28 minutes

If f(x) and f-1 (x)
are inverse functions of each other and f(x) = 2x+5, what is f-1 (8)?
Answer:
For this case we have the following function:
f (x) = 2x + 5
Clearing x we have:
2x = y - 5
x = (y-5) / 2
Rewriting:
f (x) ^ - 1 = (x-5) / 2
Evaluating x = 8:
f (8) ^ - 1 = (8-5) / 2
f (8) ^ - 1 = 3/2
