A car travels 50 mph for 10 minutes. How many miles per minute is the car traveling? To the nearest tenth of a mile, how far doe

ozzi

We are required to convert the speed from miles per hour to miles per minute;
speed of the car=50 mph
the speed in miles per minute will be as follows;
1 hr=60 min
thus the speed will be given by:
speed=distance/time
=(50 miles)/(1 hours)
=(50 miles)/(60 min)
=5/6 m/min
thus the distance traveled in 10 min will be:
distance=speed*time
=5/6*10
=8 1/3 miles

Leslie took a total of 40 quizzes over the course of 5 weeks. After attending 7 weeks of school this quarter, how many quizzes w

kow [346]

Answer:

56 quizzes

Step-by-step explanation:

40 quizzes = 5 weeks

To find the unit rate of quizzes / week, we can divide both sides by 5

40/5 quizzes = 5/5 weeks

8 quizzes = 1 week

Multiply both sides by 7 to find the amount of quizzes in 7 weeks

8 * 7 quizzes = 1 * 7 weeks

56 quizzes = 7 weeks

A lake was stocked with 360 trout. Each year, the population decreases by 10. The population of trout in

almond37 [142]

Answer:

Part A) The y-intercept is the point (0,360) and the x-intercept is the point (36,0)

Part B) The graph in the attached figure

Part C) see the explanation

Step-by-step explanation:

Part A) Find the intercepts

Let

x ----> the number of years

f(x) ----> the population of trout in the lake

we have

$f(x)=360-10x$

This is a linear function in slope intercept form

$f(x)=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

$m=-10\ \frac{trout}{year}$ ---> is negative because is a decreasing function

$b=360\ trouts$ ---> initial value

The y-intercept is the point (0,360)

Find the x-intercept

The x-intercept is the value of x when the value of f(x) is equal to zero

so

For f(x)=0

$0=360-10x$

Solve for x

$10x=360\\x=36$

The x-intercept is the point (36,0)

Part B) Graph the function

Plot the intercepts and join the points to graph the line

see the attached figure

Part C) Complete the interpretation of the intercepts

The x-intercept is the value of x when the value of f(x) is equal to zero

In this context, the x-intercept is the number of years, when the population of trouts is equal to zero

so

In 36 years, the population of trouts will be equal to zero

The y-intercept is the value of f(x) when the value of x is equal to zero

In this context, the y-intercept is the population of trouts when the number of years is equal to zero

so

Initially the population of trouts in the lake was 360 trouts

Please help fast! I'm being timed. What is the value of x?

Naddika [18.5K]

That's Intersecting Secants, and we get

EC × ED = EB × EA

(x+4)(x+4+1) = (x+1)(x+1+11)

(x+4)(x+5) = (x+1)(x+12)

x^2 + 9x + 20 = x^2 + 13x + 12

8 = 4 x

x = 2

Check: 3(14)=42 6(7)=42 good

A tank currently holds 5 gallons of water.it is being filled at the rate of 1/4 gallon per minute.how long will it take for the

LenKa [72]

Answer:

16 minutes

Step-by-step explanation:

Because the tank already holds 5 gallons of water, you only need to find the number of minutes to fill 4 gallons of water.

Because it fills at a rate of 1/4 gallons a minute, it takes 4 minutes per gallon of water.

Since we are dealing with 4 gallons of water to be filled, we multiply 4 · 4 to get the number of minutes.

4 · 4 = 16

16 minutes
