4/5 of Peter's money is twice as much as Weimin's money. What fraction of Peter's money is Weinim's money?
Answer: [tex]\dfrac25[/tex]
Step-by-step explanation:
As per given,
[tex]\dfrac45\times(\text{Peter's money})=2 (\text{Weimin's money})[/tex]
Let x= Weimin's money
Then [tex]\dfrac45\times(\text{Peter's money})=2x[/tex]
[tex]\text{Peter's money}=2x\times\dfrac54\\\\\Rightarrow\ \text{Peter's money}=\dfrac52x[/tex]
The required fraction= [tex]\dfrac{\text{Weinim's money}}{\text{Peter's money}}[/tex]
[tex]=\dfrac{x}{\dfrac{5}{2}x}=\dfrac{1}{\dfrac52}\\\\\\=\dfrac25[/tex]

Mal works at a photo gallery. He charges $50 for a large photo and $40 for a large frame. Sales tax is 5%.
How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.
Answer:
The total amount that the consumer had to pay for both products was $ 94.50.
Step-by-step explanation:
Given that Mal sold a large photo for $ 50 and a large frame for $ 40, and that the sales tax for these products is 5%, to determine the total amount that the consumer had to pay to purchase these products arises from the following calculation:
(50 + 40) x 1.05 = X
90 x 1.05 = X
94.5 = X
Therefore, the total amount that the consumer had to pay for both products was $ 94.50.
Answer:
1. Evaluate the expression: $4.50
2. Expand the expression: 2.5 + 2 = 4.5 (4.50)
3. Total tax is 4.50. yes, both the evaluating and expanding got me the same answer.
4. Expanded Expression
Step-by-step explanation:
1. 0.05(50 + 40) evaluated is 4.50
2. I broke apart 4.50 into different numbers and got 2.5 + 2

10. The total cost of a candy bar and a bag of chips is $1.70. If the cost of a candy bar and 2 bags of chips is
$2.45, what is the cost of a candy bar?
Answer: maybe 75 cents
Step-by-step explanation:
Answer:
The cost of a candy bar is $0.75.
Step-by-step explanation:
With the provided first sentence preceded along the lines, 'total cost of a candy bar and a bag of chips is $1.70.'
--Intially, determine the quotient of 1.70 and the two quantities.
+ Result should be 0.85
Thus symbolizing .85 is the valid price of a candy bar and a bag of chips.
------------------------- Although, we are not done. -----------------------------------
Let's take the second sentence into account.
"If the cost of a candy bar and 2 bags of chips is $2.45, what is the cost of a candy bar?"
Determine the sum of .75 and (.85*2)
Alert: .75 came from subtracting 10 from the intial .85
Thus the sum is $2.45, which was stated earlier as the cost of a candy bar and 2 bags of chips.

e. what will the sum of their ages be two years from now?
f. what will the difference of their ages be two years from now
will mark the brainliest.
Answer: See explanation
Step-by-step explanation:
a. how old is Cheryl?
Cheryl's age = d + 5
b. how old is Brandon?
d + 5 + 2
= d + 7
c. what was the difference in their ages 5 years ago?
Cheryl age five years ago = d
Brandon's age five years ago = d + 2
Difference = d + 2 - d = 2 years
d. what is the sum of their ages now?
Cheryl's age = d + 5
Brandon age = d + 7
Sum = d + 5 + d + 7
= 2d + 12
e. what will the sum of their ages be two years from now?
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Sum = d + 7 + d + 9
= 2d + 16
f. what will the difference of their ages be two years from now
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Difference = Brandon age - Cheryl age
= (d + 9) - (d + 7)
= 2 years.
7. Make a box-and-whisker plot for the data. What is the upper quartile value?
56 32 48 52 51 53 48 38 35 42 40 46 54 50
In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.
42 43 47 48 51 52 56 56 58 60 62 64 65 66
Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64
+ 65 + 66) ÷ 14
Mean of the data = 770 ÷ 14
Mean of the data = 55
Median = (56 + 56) ÷ 2
Median = 112 ÷ 2
Median = 56
Lowest value = 42
Highest value = 66
Range = Highest value - Highest value
Range = 66 - 42
Range = 24
Lower Quartile = 25% of the data
Lower Quartile = 48
Upper Quartile = 75% of the data
Upper Quartile = 62

Variable- it doesnt really matter. Im just going to use X.
Equation- $16.35 + x = $39.75.
The solution is $23.40
Step-by-step explanation: Basically you reverse the equation so it says $39.75 - $16.35 = x . Then you just subtract.
Answer:
$23.40
Step-by-step explanation:
To find how much she spent on the bracelet, subtract how much she spent on the pair of sunglasses from her total amount
$39.75- $16.35=$23.40

In the triangles, Line segment G K is-congruent-to line segment P N and Line segment G H is-congruent-to line segment M P.
Triangles G H K and P M N are shown. The length of side H K is 32 centimeters. The length of side M N is 40 centimeters. The lengths of sides H G and M P are congruent. The lengths of sides G K and P N are congruent.
Which statement correctly compares the angles?
Angle G is congruent to angle P.
Angle G is smaller than angle P.
Angle G is larger than angle P.
Angle G is congruent to angle N.
Answer:
B). Angle G is smaller than Angle P
Step-by-step explanation:
Given that,
GK ≅ PN,
GH ≅ MP
HK = 32 cm
MN = 40cm
and the other lengths are congruent.
This suggests that although the triangles are congruent yet they are not similar. Hence, the second statement correctly compares the angles that 'angle P is greater than angle G.'

Amelia is deciding between two landscaping companies for her place of business.
Company A charges $35 per hour and a $250 equipment fee. Company B charges $25
per hour and a $300 equipment fee. Let A represent the amount Company A would
charge for t hours of landscaping, and let B represent the amount Company B would
charge for t hours of landscaping. Write an equation for each situation, in terms oft,
and determine which company would be cheaper if Amelia needs 7 hours of
landscaping.
Answer: B is Cheaper
Step-by-step explanation: Pic is attached. It is the initial price plus the money they charge per hour, multiplied by hour. From there it is just plugging in 7 for the hour. Hope this helps!
Company B would be cheaper than Company A for 7 hours of landscaping.
What is an equation?Two or more expressions with an equal sign are defined as an equation.
Given that, Company charges $35 per hour and a $250 equipment fee while Company B charges $25 per hour and a $300 equipment fee.
The amount charged by Company A for t hours of landscaping is:
A = 35t + 250 (1)
Similarly, the amount charged by Company B for t hours of landscaping is:
B = 25t + 300 (2)
Now, solve equation (1) for t = 7:
A = 35 (7) + 250
A = 245 + 250
A = 495
Hence, company A would charge $495 for 7 hours of landscaping.
Similarly, solving equation (2) for t = 7:
B = 25(7) + 300
B = 175 + 300
B = 475
Hence, company B would charge $475 for 7 hours of landscaping.
Therefore, Company B would be cheaper than Company A for 7 hours of landscaping.

The lengths of the sides of a triangle are in the extended ratio 4:7:10. The perimeter of the triangle is 105 cm. What are the lengths of the sides?
The lengths of the sides of the triangle in cm are
Answer:
20cm, 28cm, 40cm
Step-by-step explanation:
Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.
4x + 7x + 10x = 105
21x = 105
x = 105 ÷ 21
x = 5
Shortest side (4x) = 5 × 4
Shortest side (4x) = 20
Middle side (7x) = 7 × 4
Middle side (7x) = 28
Longest side (10x) = 10 × 4
Longest side (10x) = 40
