Answer:
42.5
Step-by-step explanation:
Answer:
x = 37.5
Step-by-step explanation:
First, you'll have to find the amount between the similar triangles. This is what I mean:
42.5/17 = 2.5
20/8 = 2.5
So, that means that 15(2.5) = x.
x = 37.5

a line is perpendicular to y - 5 = -1/4(x + 8) and goes through the point (-1,2). What is the lines y-intercept?
Answers
Answer:
y = 4x + 6
Step-by-step explanation:
Turn the equation we are given into slope-intercept form.
y - 5 = -1/4(x + 8)
y - 5 = -1/4x - 2
y = -1/4x + 3
The slope of a perpendicular line is the opposite reciprocal of the original line.
-1/4 -> 4/1 -> 4
Find the new y-intercept using the point given.
y = 4x + b
2 = 4(-1) + b
2 = -4 + b
6 = b
Fill in everything we solved for.
y = 4x + 6

Min Jee wants to build a small patio. It will be 70 inches long and 49 inches wide. She can't decide whether to use brick or concrete paver stones. Each brick covers an area of 3 1/2inches by 7 1/2 inches and costs $0.59. Each paver covers an area 8.4 inches by 8.4 inches and costs $1.88. Which would be less expensive to use, and by how much?
Answers
Step-by-step explanation:
firstly, let us solve for the area of the patio, from the information given the patio we have a rectangular orientation.
Area of patio
length=70in
width=49in
Area=70x49
Area=3430in^2
Area of brick
length=7.5in
width=3.5in
Area=7.5x3.5
Area=26.25in^2
Amount of brick needed =3430/26.25
Amount of brick needed =130.66
The Total cost of brick=130.66x0.59
The Total cost of brick=$77.09
Area of paver
length=8.4in
width=8.4in
Area=8.4x8.4
Area=70.56in^2
Amount of brick needed =3430/70.56
Amount of brick needed =48.61
The Total cost of brick=48.61x1.88
The Total cost of brick=$91.38
Brick would be less expensive by =91.38-77.09= $14.29

Ali invests $4,078 in a retirement account with a fixed annual interest rate of 7% compounded
continuously. What will the account balance be after 14 years? (round your answer to the nearest
dollar, and do NOT put a $ in your answer.
Answers
Answer:
The account balance will be $10,866 after 14 years
Step-by-step explanation:
Compound continuous interest can be calculated using the formula:
[tex]A=Pe^{rt}[/tex]
A = the future value of the investment, including interestP = the principal investment amount (the initial amount)r = the interest rate t = the time the money is invested forLet us use this rule to solve the question
∵ Ali invests $4,078 in a retirement account
∴ P = 4,078
∵ The account with a fixed annual interest rate of 7% compounded
continuously
∴ r = 7% = [tex]\frac{7}{100}[/tex] = 0.07
∵ The time is 14 years
∴ t = 14
Substitute these values in the rule above to find A
∵ [tex]A=4,078(e)^{0.07(14)}[/tex]
→ Use the calculator to find the value of A
∴ A = 10,865.65255
→ Round it to the nearest dollar
∴ A = $10,866
∴ The account balance will be $10,866 after 14 years

A dealer bought an article for Rs1500 and sold it at 20 percent profit . what was rhe sale price of the article?
pls solve this question i will mark as a brainlist.
Answers
[tex]\large\underline{\underline{\red{\rm\blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]
Given that , a dealer bought an article for Rs 1500 and sold it at a profit of 20% .
So , here ,
Cost price of the article = Rs 1500.Profit on the article = 20% .Since the article is sold at profit , the Selling price of the article will equal to Cost price + 20% of cost price .
Firstly let's Calculate 20% of 1500 .
= 20% of Rs 1500 .
= 20/100 × Rs 1500 .
= Rs 300 .
Hence we can find now Selling price as ,
[tex]\boxed{\green{\bf Selling\: Price=Cost\:Price+Profit}}[/tex]
⇒ SP = CP + Profit .
⇒ SP = Rs ( 1500 + 300 ).
⇒ SP = Rs 1800 .
Hence the required answer is Rs 1800.

what is the slope of this line?
Answers
Answer:
slope is 1/4
Step-by-step explanation:
Use rise over run
The slope of the line will be equal to 1/4.
What is a slope?
Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is the ratio of the rise to the run of the line.
The formula to calculate the slope of the line is given as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the line is passing through points ( 0,6) and (8,8). The slope of the line is calculated below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = (8 - 6 ) / ( 8 - 0)
Slope = 2 / 8
Slope = 1 / 4
Therefore, the slope of the line will be equal to 1/4.
