Answer:
8 ounces of 20%12 ounces of 70%
Step-by-step explanation:
Let 'x' be the number of ounces of 20% solution'y' be for the 70%
solutionSince the the mix is 50% of 20 ounces then:x + y = 200.20x +
0.70y = 0.50(20)From the 1st equation solve for xx = 20 - ySubstitute it to
the 2nd equation0.2(20-y) + 0.7y = 104 - 0.2y + 0.7y = 100.5y = 10-40.5y =
6y = 12Substitute to x = 20 - yx = 20 - 12x = 8

Step 1: Find the area of the rectangle
Area of a rectangle = base x height
Area of the rectangle = 4 x 10 = 40
Step 2: Find the area of the half-circle
Area of a circle = pi x r^2
---In this case, since we only have half of a circle, we will need to divide the area by 2 (or multiply by 1/2).
---We are also only given the diameter here. The radius of a circle is half of its diameter, therefore the radius of this half-circle is 5.
Area of the half-circle = (pi x 5^2) / 2 = (3.14 x 25) / 2 = (78.5) / 2 = 39.25
Rounded area of the half-circle = 39.3
Step 3: Find the area of the figure
Now that we know both parts of the figure, all that's left to do is add them together to find the total area.
40 + 39.3 = 79.3
Answer: 79.3

Find the unique four-digit integer n with these properties:
The last digit (the units digit) of n is 9.
The digits of n add up to 27.
Two digits of n are the same.
n is a perfect square.
Answer:
3,969
Step-by-step explanation:
If n is a perfect square, then the last digits of the prefect square must be 3 or 7 because n ends in 9.
Since n is 4 digits the number can only land between 33 and 97.

Answer:
San Francisco is the fastest
Step-by-step explanation:
The reason why is because you have to get the hours the same soooo...
You can get all of the hours to 12. So Ph= 3hours so 3x4=12 and what you do on one side you have to do on the other. So 1689x4=6756 next M=2 hours so to get it to 12 you do 2x6=12. Then 913x6=5478. Next San=4 hours
4x3=12 next 3x2556=7668 Sooooooo.... Put the data together
In 12 hours Ph goes 6756 miles
In 12 hours M goes 5478 miles
In 12 hours San goes 7668 miles
So the answer is San because it has the biggest number

The leading brand of cosmetics in the US had about 20% of the total sales in the industry. The total sales were $ 200,000. What was the leading brands sales? Show your work.
Answer:
$0.52 billion
Step-by-step explanation:
Given data
We are given that the total sale in the industry is $2.6 billion
And the leading brand has about 20% of the total sale
Hence the leading brand's sale is
=20/100*2.6
=0.2*2.6
= $0.52 billion
Therefore the leading brand's sale is about $0.52 billion

Answer:
These are alternate exterior angles
x=14
Step-by-step explanation:
Alternate exterior angles are formed by two parallel and one transversal line.
I suggest you do some research on transversal angles. I think that would be really helpful in the near future :)
Alternate exterior angles are also equal
Knowing this, we now understand:

Jake has 900 cm³ of material. He uses 14.5 cm³ to make a right triangular prism. He wants to make a second prism that is a dilation of the first prism with a scale factor of 4.
How much more material does Jake need in order to make the second prism?
Select from the drop-down menu to correctly complete the statement.
Jake needs an additional (13.5, 28, 42.5)
cm³ of material to make the second prism.
Jake needs an additional 42.5 cm³ of material to make the second prism.
Amount of material availableSince Jake has 900 cm³ of material and he uses 14.5 cm³ to make a right triangular prism. The amount of material available to make the second prism is V = 900 cm³ - 14.5 cm³
= 885.5 cm³
Scale factor
Now, the second prism is gotten by ditaion of the first prism by a factor of 4.
Since we have volume, (scale factor)³ = volume of second prism/volue of first prism
Volume of second prismSo, volume of second prism, V' = (scale factor)³ × volume of first prism = 4³ × 14.5 cm³ = 928 cm³
Amount of material more neededSo, the amount of material more needed to make the second prism is V"' = V' - V = 928 cm³ - 885.5 cm³
= 42.5 cm³
So, Jake needs an additional 42.5 cm³ of material to make the second prism.

You have a coin and a dice. Flipping the coin, you can either get heads or tails facing up. There are 6 numbers on the dice, numbered 1-6. What is the probability of flipping tails and getting the numbers 3 or 4 on the dice?
Answer:
3 = (50.000%)
4 = (66.667%)
Step-by-step explanation:
3 out of 6 = 3/6
4 out of 6 = 4/6
3/6 in decimal form is 0.5
4/6 in decimal form is 0.6666 (the six repeats forever)
0.5 out of 1 is 50%
0.6666 (the six repeats forever) out of 1 is about 66.667%
0.5 = (50.000%)
0.66667 (rounded) = (66.667%)
Demarcus has to wrap a gift for his friend's birthday party. The gift is in a rectangular box with the dimensions shown below. He's trying to figure out how much gift wrap he needs to cover the entire box. Should he calculate the total surface area or the lateral surface area? Pick the right measurement and then calculate it for him.
In your answer, specify whether he should use total surface area or lateral surface area. Calculate the one you choose, give that measurement of the box, and then explain how you calculated it.
Answer:
Surface Area = 2lw + 2lh + 2hw = 2(lw+lh + hw) = 2(12x8 + 12x4 + 4x8) = 2(96+48+32) = 2(176) = 352 square inches

Gabrielle and Rob earn a total of $2,560 this week. With their total earnings from the week, Gabrielle buys 2 train tickets that cost $215.80 each, and Rob buys 2 suitcases that cost $36.50 each. Which statement is true?
A) Gabrielle and Rob have $ 2,055.40 of the $2 ,560 left because 2,560 − 2( 215.80 ) − 2(36.50 ) is equal to 2,055.4.
B)Gabrielle and Rob have $2,091.90 of the $2,560 left because 2,560−2(215.80)−36.50 is equal to 2,091.9.
C)Gabrielle and Rob have $2,271.20 of the $2,560 left because 2,560−215.80−2(36.50) is equal to 2,271.2.
D)Gabrielle and Rob have $2,307.70 of the $2,560 left because 2,560−215.80−36.50 is equal to 2,307.7.
Answer:
A
Step-by-step explanation:
215.80 + 215.80 = 431.60
36.50 + 36.50 = 73
431.60 + 73 = 504.60
2560 - 504.60 = 2055.40
The correct statement is:
Gabrielle and Rob have $2,055.40 of the $2,560 left because 2,560 − 2(215.80) − 2(36.50) is equal to 2,055.4.
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Gabrielle and Rob's total earnings for the week are $2,560.
If Gabrielle buys 2 train tickets that cost $215.80 each.
She spends a total of:
\$431.60 (2 x 215.80).
If Rob buys 2 suitcases that cost $36.50 each, he spends a total of:
$73 (2 x 36.50).
To find out how much money they have left, we need to subtract the amount spent on tickets and suitcases from their total earnings:
$2,560 - $431.60 - $73
= $2,055.40
Therefore,
The correct statement is:
Gabrielle and Rob have $2,055.40 of the $2,560 left because 2,560 − 2(215.80) − 2(36.50) is equal to 2,055.4.
