Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting

line. Chana skated 3 meters per second and Josiah skated 2 meters per second.
CORRECT (SELECTED)
Josiah's distance from the starting line at a time when he is behind Chana.

Explanation: Point F is on line a, so it does represent Josiah's distance at a certain time. Also, point F is below line b, so it represents a distance that is less than Chana's distance.

Josiah and Chana travel at constant and different speeds.

  • The point F indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana

<h3>How can the what the the point <em>F </em>represent be known?</h3>

Josiah's head start = 10 meters from the start

Josiah's speed = 2 m/s

Chana's speed = 3 m/s

Expressing the distance traveled as an equation, we have;

D = d + s × t

Where;

D = The distance covered

d = The distance from the starting line the runner starts

s = The speed of the runner

t = The time spent running

For Josiah, we have;

D = 10 + 2•t (line <em>a</em>)

For Chana, we have;

D = 0 + 3•t = 3•t (line <em>b</em>)

The above equations are straight line equations.

The point <em>F </em>is on line <em>a</em>, which shows Josiah distance after 25 seconds which is 60 meters. The corresponding point on line <em>b</em>, Chana's distance after 25 minutes is 75 meters.

Therefore;

  • The point <em>F </em>indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana

Which graph represent the solution to the given systems y=-x +4 y=1/3x + 8
Furkat [3]
Use substitution

-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3

Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.

y = -(-3) + 4
y = 7

Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and
serious [3.7K]

The Viola’s monthly payment more than the loan is unsubsidized than if the loan is subsidized is $35.05.

<h3>What is compound interest?</h3>

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

A=P\left(1+\dfrac{R}{n\times100}\right)^{nt}

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and an interest rate of 7. 5%, compounded monthly.

Put this values in the above formula as,

A=8470\left(1+\dfrac{7.5}{12\times100}\right)^{12\times4}\\A=11422.6348

For the four years, the monthly payment is,

m=\dfrac{11422.6348}{12\times4}\\m=237.97

The monthly payment of unsubsidized loan is $237.97.

The monthly payment of subsidized loan is $202.80.

The difference between the unsubsidized and subsidized loan monthly payment is,

d=237.97-202.80\\d=35.17\\d\approx 35.05

Thus, the Viola’s monthly payment more than the loan is unsubsidized than if the loan is subsidized is $35.05.

A cone with a height of 50 meters has a volume of 5400π meters cubed. What is the radius of the cone?
Sergeu [11.5K]

Answer:

A

Step-by-step explanation:

The volume of a cone has the formula:

V=\frac{1}{3}\pi r^2 h

Where

V is the volume

r is the radius

h is the height

Given,

h = 50

V = 5400π

We want the radius, r.

Lets substitute and solve for r:

V=\frac{1}{3}\pi r^2 h\\5400\pi=\frac{1}{3}\pi r^2(50)\\5400\pi=\frac{50\pi r^2}{3}\\50\pi r^2=16200\pi\\r^2=324\\r=\sqrt{324}\\r=18

The radius is 18 meters

Correct answer A

A bike wheel. The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What
AleksandrR [38]

Answer:

a. 800 grams = 1.76 pounds

b. 700 grams = 1.54 pounds

Step-by-step explanation:

Here is a weight conversion problem.

In this question, we shall be making conversions from grams to pounds.

Kindly note that 453.592 grams = 1 pound as stated in the question

a. 800 grams

Kindly recall;

453.592 grams = 1 pound

800 grams = x pound

Thus;

453.592 * x = 800 * 1

x = 800/453.592

x = 1.764 pounds which is 1.76 pounds to 2 decimal places

b. 700 grams

1 pound = 453.592 grams

y pound = 700 grams

y * 453.592 = 700 * 1

y = 700/453.592

y = 1.543 pounds which is 1.54 to 2 decimal places
