jamie is running a race that is 26.2 miles long and she is running at a speed of 8 miles per hour. she has completed 3/4 of the race already.How much longer will it take her to finish the race?

Answers

Answer:

  49 1/8 minutes

Step-by-step explanation:

Jamie has 1/4 of the 26.2 mile distance to go, so must finish ...

  (26.2 mi)/4 = 6.55 mi

The time in hours required to do that is found by dividing distance by speed:

  time = distance/speed = (6.55 mi)/(8 mi/h) = 0.81875 h

In minutes, this is ...

  (0.81875 h)×(60 min/h) = 49.125 min = 49 1/8 min

It will take Jamie 49 1/8 minutes to finish the race at her current speed.

Ronda Rollins gets a Social Security benefit of $350 per month. Her husband receives a benefit equal to 200 percent of Ronda's benefit. If they take an additional $400 per month from savings, what will their monthly income be?700
750
1,050
1,450

Answers

Answer

Find out the what will their monthly income be .

To proof

Let us assume that the their monthly income be x .

As given

Ronda Rollins gets a Social Security benefit of $350 per month

Her husband receives a benefit equal to 200 percent of Ronda's benefit.

If they take an additional $400 per month from savings .

200% written in the decimal form

= (200)/(100)

Than the equation becomes

x = 350 + 2* 350 + 400

x = 350 + 700 + 400

x= $1450

Therefore  monthly income be $1450 .

Option (D) is correct .

Hence proved
350+(2*350)+400=1450

Answer:

B

Step-by-step explanation:

First simplify the first term to get

10y^4

then multiply 10y^4 by 4 square root 6y^3

40y would be all you needed to get answer

Answer:

40y^5√6y (B)

Step-by-step explanation:

Let's multiply 2√25y^8 * 4√6y^3:

8√150y^11 (When you multiply exponents with the same base, you can just add the exponents and keep the same base:

Ex. 4^5 * 4^9 = 4^14)

Let's simplify 8√150y^11

√150 = 5√6

√y^11 = y^5√y

So our final answer would be:

40y^5√6y

A skydiver weighing 160 lb (including equipment) falls vertically downward from an altitude of 20,000 ft and opens the parachute after 18 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.7|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity vis measured in ft/s. Assume that acceleration due to gravity has magnitude 32 ft/s; remember that weight is the product of mass and gravitational acceleration.Required:a. Find the speed of the skydiver when the parachute opens.b. Find the distance fallen before the parachute opens.c. What is the limiting velocity vL after the parachute opens?d. Determine how long the sky diver is in the air after the parachute opens.e. Plot the graph of velocity versus time from the beginning of the fall until the sky diver reaches the ground.
Can someone help me with math?Come up with and describe two scenarios: one that models a direct variation situation and one that models an inverse variation situation. Do not state explicitly which scenario is which, but provide at least four data pairs for each situation. Your classmates will have to determine which of the scenarios is a direct variation and which is an inverse variation, and the value of k for each.
