Kyra is participating in
i fundraiser walk-a-thon. She walks| 2 miles in 30 minutes. If she continues to walk at the same rate, determine how
many minutes it will take her to walk 7 miles.

Answers

Answer 1

Kyra takes 105 minutes to cover a distance of 7 miles if she walks at  a speed of 1/15 miles per minute.

Given,

Kyra is participating in a fundraiser walk-a-thon.

She walks 2 miles in 30 minutes

We have to find the time taken by Kyra to cover 7 miles if she continues the same rate of speed;

Here,

2  miles in 30 minutes

Then,

Speed = distance / time

Speed = 2 / 30

Speed = 1/15 miles per minute

Now,

The time taken to cover 7 miles;

Speed = distance / time

1/15 = 7 / t

t = 7 x 15

t = 105 minutes

That is,

Kyra takes 105 minutes to cover a distance of 7 miles if she walks at  a speed of 1/15 miles per minute.

Answer:

y = (24/5)x + 24

Step-by-step explanation:

Knowing that the parent equation for linear functions is "y = mx+b", where "m = slope" and "b = y-intercept", we can create an equation for the line of best fit.

We also need to know the formula for using two points to find the slope is  "(y2 - y1)/(x2 - x1)", where (x2, y2) is a point on the graph and (x1, y1) is a point on the graph.

Finding the slope:

I will be using points (5, 48) and (0, 24).

(24 - 48)/(0 - 5)

(-24)/(-5)

24/5      is the slope so "m = 24/5"

We can tell from the graph (0, 24) is the y-intercept, so "b = 24"

Final equation:

y = (24/5)x + 24

function?
Check all that apply.
A. It goes through the origin.
B. It has a slope of 1.
C. It is a parabola.
D. It is a straight line.

Answers

The following are the characteristics of the graph of the linear parent function:

B. It has a slope of 1.

C. It is a parabola.

D. It is a straight line.

Lets explain the meaning of linear parent function

- A linear parent function is the equation y = x or f(x) = x

- A parent function is the simplest equation of a function

- It represented by a straight line passing through the origin point O

- The x-coordinate and the y-coordinate of any points lie on it are equal

- The slope of the line is 1 because the slope is the change of Δy/Δx

and Δy = Δx

The characteristics of the graph of the linear parent  function are

∵ Linear parent function is f(x) = x and f(x) = y

∴ x = y

∵ The slope = Δy/Δx

∵ Δx = Δy because x = y

∴ The slope of it is 1

B. It has a slope of 1

∵ y = 0

∵ If x = 0 then y must = 0

∴ It goes through the origin

C. It goes through the origin

∵ It is a linear function

∵ All linear function represented by a straight line

∴ The graph of the linear parent function is a straight line

D. It is a straight line

Hence we get the right answers.

At time t = 0, water begins to drip out of a pipe
nto an empty bucket. After 56 minutes, 8 inches
of water are in the bucket. What linear function
n the form y = mx + b represents the amount of
water in inches, w, in the bucket after t minutes?

Answers

Step-by-step explanation:

w = t/7

at the beginning we 0 inches of water.

after 56 minutes we have 8 inches of water.

that is a ratio of 56 minutes / 8 inches = 7/1 = 1 / 1/7.

so, in 1 minute we get 1/7 inch of water.

in 2 minutes 2×1/7 = 2/7.

in 3 minutes 3×1/7 = 3/7.

...

hence the equation.

Answer:

y = t/7

Step-by-step explanation:

Given

Start time t = 0,Start level y = 0,Level of y = 8 in after t = 56 min

Solution

Find the value of m and b in the equation y = mx + b.

The value of b = 0, since there is no level in the bucket initially.

Find the value of m, the slope:

8 = 56m,m = 8/56m = 1/7

So the equation is:

y =  (1/7)t + 0

or

y = t/7

Students from the local high school are selling tickets to the town's annual carnival. Adult admission is $4.00 and child admission is $2.00. Four hours after the carnival opened its first day, 440 tickets had been sold totaling $1380. How many adults and how many children entered the carnival after it was opened?

Answers

The number of adults is 200 and the number of children that entered the carnival after it was opened is 240.

How to find the number tickets sold?

Let a represent the number of adult tickets sold

Let c represent the number of children tickets sold

4a + 2c = 1380

Hence,

a + c = 440

Solving  for c

4 (440-c) +2c = 1280

1760-4c +2c = 1280

-4c+2c = -480

-2c=-480

Divide both side by -2c

c = -480/-2

c = 240 (children tickets)

Solving for a

a =440-c

a =440 -240

a=200 (Adult tickets)

Therefore 240 and 200 tickets were sold.

According to a study done by UCB students, the height for Martian adult males is normally distributed with an average of 65 inches and a standard deviation of 2.4 inches. Suppose one Martian adult male is randomly chosen. Let X = height of the individual. Round all answers to 4 decimal places where possible.

Answers

The probability that the person is between 67.1 and 68.3 inches, using the normal distribution, is of:

0.1056 = 10.56%.

Normal Probability Distribution

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

The mean and the standard deviation for the heights of UCB students are given as follows:

[tex]\mu = 65, \sigma = 2.4[/tex]

The probability that the person is between 67.1 and 68.3 inches is the p-value of Z when X = 68.3 subtracted by the p-value of Z when X = 67.1, hence:

X = 68.3:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (68.3 - 65)/2.4

Z = 1.38.

Z = 1.38 has a p-value of 0.9162.

X = 67.1:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (67.1 - 65)/2.4

Z = 0.88.

Z = 0.88 has a p-value of 0.8106.

0.9162 - 0.8106 = 0.1056 = 10.56%.

Answers

An amount of $1800 was invested at a rate of 7.5% and $800 was invested at a rate of 5%.

What is the percentage?

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, one part of $2600 was invested at a rate of 7.5% and the other part was invested at a rate of 5%, and the total yield was $175 simple interest.

Let $x was invested at 7.5%, then $(2600-x) was invested at 5%.

Since the yield is $175, it follows,

7.5% of x + 5% of (2600-x) = 175

7.5x/100 + 5(2600-x)/100 = 175

7.5x + 13000 - 5x = 17500

2.5x = 17500-13000

2.5x = 4500

x = 1800

Now, the value of (2600-x) is,

Sum of all the interior angles of the heptagon is equal to 900.

Given measure of all the angles of the heptagon is given by :

135°+( 5x - 4 )° +( 7x - 64 )° + 120° +( 6x - 8 )° +( 4x + 15 )° + ( 3x + 31 )°= 900°

Arrange all the like terms of the given expression together we get,

⇒ ( 5x + 7x + 6x + 4x + 3x )° + ( 135 - 4 - 64 + 120 - 8 + 15 + 31 )°  = 900°

⇒ 25x° + 225° = 900°

⇒ 25x° = 900° -225°

⇒ 25x° = 675°

⇒ x = 27°

Therefore,  for the given measures of angles of heptagon, the value of x is equal to 27° .

(b) The graph of y=g(x) is shown. Draw the graph of y=g(1/2x)

Answers

The graph of the piece-wise function g(0.5x) is given by the second image at the end of the answer.

What is a piecewise-defined function?

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

In this problem, the function given by the first graph has two definitions, as follows:

To the left of x = 0.To the right of x = 0.

The two functions are linear with intercept 0, hence the definitions are given as follows:

x < 0: y = 2x, as when x increases by 1, y increases by 2, hence slope of 2.x > 0: y = -0.5x, as when x increases by 2, y decreases by 1, hence slope of -0.5.

After the transformation x -> 0.5x, the definitions are given as follows:

g(0.5x) = 2(0.5x) = x, x < 0.g(0.5x) = -0.5(0.5x) = -0.25x, x > 0.
