Solve for k, the constant of variation, in an inverse variation problem where y=17 x=6

Answers

Answer:

k = 102

Step-by-step explanation:

Inverse variation is represented as follows:

y = k/x

Find k by substituting 17 for y and 6 for x:

17 = k/6

Multiplying both sides by 6 results in k = 102

A cylinder has a diameter of 5 inches. Which equation can be used to find V, the volume of the cylinder in cubic inches?

Answers

Answer:

V=  π*2.5^2*h

Step-by-step explanation:

Given data

Diameter d= 5 in

radius=d/2= 5/2= 2.5in

We know that the formula for the cylinder volume is given as

V= πr^2h

substitute

V=  π*2.5^2*h

Hence the expression for the volume with a given height is

V=  π*2.5^2*h

Answer: 143

90-53=37

180-37=143

Answer:

Step-by-step explanation:

The angle left to b is

90° - a

= 90° - 53°

= 37°

So now

< b + 37° = 180° ( being linear pair )

< b = 180° - 37°

the slope of the points (8,6) and (2,-2)

Answers

Answer:

4/3

Step-by-step explanation:

m = slope

m = y2 - y1 / x2 - x1

m = -2 - 6 / 2 - 8

m = -8 / -6

m = -8/-6

Negative + Negative = Positive

m = 8/6

Both numbers have a common factor of 2

m = 8 ÷ 2 / 6 ÷ 2

m = 4/3

Javon's first 3 quizzes had a mean score of 90%. If he scores 46% on his next quiz,what will be his mean quiz score for these 4 quizzes?

Answers

Answer: 79%

Step-by-step explanation:

Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:

= 90% × 3

= 270%

Since he scores 46% on his next quiz, we add it to the previous score and this will be:

= 270 + 46

= 316

Then, his mean quiz score for these 4 quizzes will be:

= Total score / Number of quizzes

= 316 / 4

= 79%

Answer:

79%

Step-by-step explanation:

316 / 4 = 79%

Two trains on opposite tracks leave the same station at the same
time. One train travels at an average speed of 80 kilometers per
hour and the other travels at an average speed of 70 kilometers
per hour. How long after they leave the station will they be 50
km apart?

Answers

Answer: The answer is 1/3 hour, or 20 minutes

Step-by-step explanation:

The combined rate of separation is (80 km/hr + 70 km/hr) = 150 km/hr,

therefore they will be 1/3 of 150 km apart after traveling 1/3 of an hour.

Which equation represents a nonlinear function? y=−85x+19.4 y = − − 8 5 x + 19.4 y=−12x2−7 y = − − 1 2 x 2 − − 7 y=x4+x y = x 4 + x y=32−4x

Answers

Answer:

The answer is below

Step-by-step explanation:

The options are not clear. I would solve a similar question.

A linear function is a function in the form:

y = mx + b;  where y and x are variables, m is the slope and b is the y intercept.

From the options:

a) y = 3x³

Since the equation is not in the form of y = mx + b, hence it is not a linear function. It is a nonlinear function.

b) 3x + 2y = 10

2y = -3x + 10

The equation is in the form of y = mx + b, hence it is a linear function.

c) y = 15.3

The equation is in the form of y = mx + b, hence it is a linear function.

d) y = (1/4)x - 2

The equation is in the form of y = mx + b, hence it is a linear function.

Emma's Pizza can make 12 pizzas in 40 minutes. How many pizzas can they make in 5 hours?

Answers

Answer:

90

Step-by-step explanation:

Change 5 hours to minutes. (5x60, and 300 minutes)

Divide 300 by 40. (7.5)

Then, multiply 7.5 by 12 (90)

Answer:

90 pizzas

Step-by-step explanation:

We know 5 hours = [tex]5\times60 = 300[/tex] minutes

If you consider 20 minutes as a period, 5 hours .as well as 300 minutes. contains [tex]\frac{300}{20} = 15[/tex] periods.

Emma can make 12 pizzas in 40 minutes.

So she can make 6 pizzas in 20 minutes (in half time)

In 1 period she makes 6 pizzas.

In 15 periods she makes [tex]15\times6 = 90[/tex] pizzas (Answer.)

Becky borrowed $580.00 from the bank. The loan had a 13.5% simple annual interest rate, and she paid off the bill over 1.5 years. What was the total amount, including interest, Becky paid for the loan?

Answers

Answer:

697.45

Step-by-step explanation:

interest for the first year = 13.5 % of 580 = 78.3

for 0.5 year, it will be 78.3 /2 =39.15

1year + 0.5 year = 78.3 + 39.15= 117.45

add that to borrowed amount to get total amount paid

117.45+ 580= 697.45

Paul finished his 800 meter race in 2 minutes and 2 seconds. Jeff finished in 121 seconds. Who finished first? (PLESES SHOW WORK)

Answers

Answer:

Jeff finished first

Step-by-step explanation:

To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes

CONVERT 2 MINUTES 2 SECONDS TO SECONDS

60 seconds = 1 minutes

to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it

2 x 60 = 120 seconds

120 seconds + 2 seconds = 122 seconds

Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first

CONVERT 121 SECONDS TO MINUTES

60 seconds = 1 minutes

To convert 121 seconds to minutes, we have to divide by 60

121/60 = 2 minutes 1 second

Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first

For his birthday, Mr. Robin and four of his friends went to a Math museum to learn about new intergalactic math. They each got a ticket for $12.00 and each bought the same calculator at the gift shop. If Mr. Robin spent $110 for the group's tickets and calculator, how much did each calculator cost? Write and solve an equation to describe this situation.

Answers

Answer: $10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for [tex]\$12[/tex] each

If each one of them bought a calculator then the total spendings are [tex]\$110[/tex]

Suppose the cost of each calculator is [tex]\$\ x[/tex]

Cost per person is given by  [tex]x+\$12[/tex]

For the group, it is [tex]5(x+12)[/tex]

Equate this to total spendings

[tex]\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10[/tex]

thus, the cost of each calculator is [tex]\$ 10[/tex]

y=0x+(-6),m=0

y=0x+(-6),m=0,b=-6

m=0,b=-6

  y=3x(-2)

Let x be the domain values.

Let x = -1

y = 3(-1) - 2

y = -6 - 2

y = -8...range

Our first ordered pair is (-1, -8).

Let x = 2

y = 4...range

Our second ordered pair is (2, 4).

Let x = 4

Area of vertically tilted rectangles

1): area = 5 x 4 = 20 yd²

Total area = 20 + 20 = 40 yd²

Area of horizontal rectangles:
