Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
scale factor = [tex]\frac{PQ}{XY}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
That is the sides of Δ PQR are half those of Δ XYZ, thus
The perimeter of Δ PQR is half Δ XYZ, that is
perimeter of Δ PQR = [tex]\frac{1}{2}[/tex] × 20 = 10

What is the solution to 34x+85=3(13x+7)
Answer:
x=12.8
Step-by-step explanation:
34x+85=39x+21
34x-39x=21-85
-5x = -64
x = -64/-5
x = 12.8
Answer:
x = 34/5
Step-by-step explanation:
Just solve the equation
[tex]34x + 85 = 3(13x + 17)\\34x + 85 = 39x + 51\\85 - 51 = 39x - 34x\\34 = 5x\\x = 34/5[/tex]

Kenji is decorating papers with a total of 15 heart stickers and 12 star stickers for the child he is babysitting. If he wants to make all the papers identical, with the same combination of heart and star stickers and no stickers left over, what is the greatest number of pages Kenji can decorate?
Answer: The greatest number of pages Kenji can decorate = 3
Step-by-step explanation:
Given: Total heart stickers = 15
Total star stickers =12
If all the papers identical, with the same combination of heart and star stickers and no stickers left over.
Then the greatest number of pages Kenji can decorate = GCD(15,12) [GCD=greatest common divisor]
Since 15 = 3 x 5
12=2 x 2 x 3
GCD(15,12) =3
Hence, the greatest number of pages Kenji can decorate = 3
A scientist had 1.25 ounces of a chemical. He bought 2.5 ounces more of the chemical and then used 0.75 ounce in an experiment. How much chemical does the scientist have remaining?
Answer:
3 ouncesStep-by-step explanation:
Step one:
given data
the initial amount of chemical = 1.25 ounces
Extra amount of chemical =2.5 ounces
Total amount of chemical =1.25+2.5=3.75 ounces
Step two:
we are told that the scientist used 0.75 ounces of chemical
Hence the remaining chemical is
remaining= 3.75-0.75
remaining= 3 ounces
The remainder is 3 ounces
Suppose there are 28,200,000 small businesses in the economy today. Twenty-five percent of those businesses have no employees. What is the number of businesses in the economy with no employees?
Answer:
the number of businesses with no employees is 7,050,000
Step-by-step explanation:
The computation of the number of businesses in the economy have no employees is shown below:
Given that
There are a total of 28,200,000
Out of which 25% of those businesses have no employees
So, the number of businesses in the economy is
= 28,200,000 × 25%
= 7,050,000
Hence, the number of businesses with no employees is 7,050,000

The cost of catering a dinner is $11.95 per person plus $25 for delivery and setup. Which statement is true about the graph of the function that represents the average cost per person?
The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.
The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
The vertical asymptote x = 0 represents that the cost per person approaches $0 as the number of people increases.
The vertical asymptote x = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
B.) The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
Good luck with the test! :)
The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.
What are asymptotes?"An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity."
"The curves visit these asymptotes but never overtake them. The method opted to find the horizontal asymptote changes involves comparing the degrees of the polynomials in the numerator and denominator of the function. If both the polynomials have the same degree, divide the coefficients of the largest degree terms."
From the equation, y = 11.95x + 25
And from the given graph it is clear that the horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.
Hence, A is the correct option.

Oil prices are projected to increase by 75% by next May. A quart of oil currently costs $2.15. What is the projected cost of a gallon of oil next May? Round your answer to the nearest hundredth.
Answer:
Future cost per gallon= $15.05
Step-by-step explanation:
Giving the following information:
Oil prices are projected to increase by 75% by next May. A quart of oil currently costs $2.15.
We know that 1 quart equals 0.25 gallons.
First, we will determine the actual cost per gallon.
Actual cost per gallon= 2.15*4= $8.6
Now, the cost for May:
Future cost per gallon= 8.6*1.75
Future cost per gallon= $15.05
Answer:
15.05

At a birthday party pizzas and sodas were purchased for the kids. The number of sodas bought was two more than three times the number of pizzas. Pizzas cost $9.50 each and sodas cost $1.25 each. (c) A total of $68.75 was spent on pizza and sodas at the party. Let n be the number of pizzas purchased. Set up an equation involving n that models the scenario. Solve it and state both the number of pizzas and the number of sodas that were bought.
Answer:
5 pizzas and 17 sodas were bought
Step-by-step explanation:
Here, we want to get the number of pizza and sodas bought
Let n be the number of pizzas bought
we are told that the number of sodas bought was 2 more than 3 times the number of pizzas
So the number of sodas will be;
3n + 2
So let’s have the equations based on the prices;
pizzas cost $9.50, soda cost $1.25
Thus;
9.5n + 1.25(3n + 2) = 68.75
9.5n + 3.75n + 2.5 = 68.75
13.25n = 68.75 - 2.5
13.25n = 66.25
n = 66.25/13.25
n = 5
Number of pizzas bought is 5
number of soda is 3n + 2 = 3(5) + 2 = 15 + 2 = 17

What would be the height of 1000 Canadian Dimes?
The height of 100 Canadian dimes is 1220 millimeter.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have 1000 Canadian dimes.
Assume that the height of 100 Canadian dimes is [x] mm. Then, we can write -
[x] = 1000 x 1.22
[x] = 1220 mm
Therefore, the height of 100 Canadian dimes is 1220 millimeter.
