A rocket ship travels at 2.0×104 miles per hour. If a satellite is 2.5×105 miles from Earth, how long will it take the rocket to make the trip from Earth to the satellite? (Hint: Divide the distance to the satellite by the speed.) Write your answer in scientific notation.

Answers

Answer 1

Answer: Time taken =1.25 x 10^1 hours 0r 4.5 x 10^4s

Step-by-step explanation:

Step 1

how long will it take the rocket to make the trip from Earth to the satellite = Time taken for the rocket to make the trip from Earth to the satellite

Speed = Distance / Time ,

Time = Distance / speed

Step 2-- solving

Time = Distance / speed

Time=2.5×10^5 miles/2.0×10^4 miles per hour

=12.5 hours = 1.25 x 10^1 hours

or 1.25 x 10^1 hours x 3600 = 45,000 seconds = 4.5 x 10^4s

Which of the equations below represents a line perpendicular to the yaxis?
A. y= x
B. y= 6x
C. x = 6
D. y=-6

Answers

Answer:

y=x

Step-by-step explanation:

Answer:

D. y = -6

Step-by-step explanation:

You can graph each line to see which one is horizontal since the y-axis is vertical. This would make the lines perpendicular since when a vertical and horizontal line meet, they form a 90-degree angle, which is by definition what perpendicular means.

if h(x)=(x/2)-6, find h(10)
A. -1
B. 14
C. 2
D. 7

Answers

Answer:

Step-by-step explanation:

if h(x)=(x/2)-6, find h(10)

What this means is that wherever there is an x on the right hand side, replace it with a 10

h(10) = (10/2) - 6

h(10) = 5 - 6

h(10) = -1

Ashley's older brother, Jamaal, is planning to ride his bicycle from Los Angeles to Washington D.C., a distance of 2,668 miles, in two months. Jamaal has decided that he will ride for three days and then rest on the fourth day. If he maintains this plan, and rides on 45 of the 60 days, what is the minimum number of miles that Jamaal must ride each day with his new plan?

Answers

Answer:

60 miles

Step-by-step explanation:

This means the number of days he will ride is

45 days

Hence, the minimum number of miles that Jamaal must ride each day with his new plan is calculated as:

Total number of miles/Number of days

= 2668 miles /45 days

= 59.288888889 miles

Approximately to the nearest whole number = 60 miles

Hence, the minimum number of miles Jamal must ride each day is 60 miles

What is the x-intercept of the line 7x - 4y = 28

Answers

Answer:

(0, 4 )

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x, that is

7x - 4(0) = 28, that is

7x = 28 ( divide both sides by 7 )

x = 4 ← x- intercept ⇒ (0, 4 ) as an ordered pair

Answers

Given:

The equation of line is

[tex]7x-5=4y-6[/tex]

To find:

The x and y-intercept of the given line.

Solution:

We have,

[tex]7x-5=4y-6[/tex]

Putting x=0, we get

[tex]7(0)-5=4y-6[/tex]

Add 6 on both sides.

[tex]0-5+6=4y[/tex]

[tex]1=4y[/tex]

Divide both sides by 4.

[tex]\dfrac{1}{4}=y[/tex]

So, the y-intercept is [tex]\left(0,\dfrac{1}{4}\right)[/tex].

Putting y=0 in given equation, we get

[tex]7x-5=4(0)-6[/tex]

Add 5 on both sides.

[tex]7x=-6+5[/tex]

[tex]7x=-1[/tex]

Divide both sides by 7.

[tex]x=\dfrac{-1}{7}[/tex]

So, the x-intercept is [tex]\left(-\dfrac{1}{7},0\right)[/tex].

x intercept: (-1/7 , 0)

Answers

Answer: Diana donates $125 each month.

Step-by-step explanation:

Let x = Amount of money Diana donates each month.

Money she donates in a year = 12x [ 1 year = 12 months]

Given: Money she donates in a year = $1500

So, [tex]12x=1500\Rightarrow\ x=\dfrac{1500}{12}=\$125[/tex]

i.e. Amount of money Diana donates each month = $125

Hence, Diana donates $125 each month.

. Volunteer drivers are needed to bring 80 students to the championship baseball game. Drivers either have cars, which can seat 4 students, or vans, which can seat 6 students. The equation 4c+6v=80 describes the relationship between the number of cars, c, and number of vans, v, that can transport exactly 80 students.

Select all statements that are true about the situation.

If 12 cars go, then 2 vans are needed.
c=14 and v=4 are a pair of solutions to the equation.
If 6 cars go and 11 vans go, there will be extra space.

If 20 cars go, no vans are needed.

8 vans and 8 cars are numbers that meet the constraints in this situation.

Step-by-step explanation:

1. If 12 cars go, then 2 vans are needed.

(4)(12)+(6)(2) = 80

60≠80

False2.c=14 and v=4 are a pair of solutions to the equation.

(4)(14)+(6)(4) = 80

80=80

True

3.If 6 cars go and 11 vans go, there will be extra space.

(4)(6)+(6)(11) = 80

90≠80

False

4. 10 cars and 8 vans isn’t enough to transport all the students.

(4)(10)+(6)(8) = 80

False and is wrong because it would leave extra space

5. If 20 cars go, no vans are needed.

(4)(20)+(6)(0) = 80

A car wash has two employees on duty.
Employee I can finish washing a car in 30 minutes.
Employee 2 can finish washing a car in 20 minutes.
.
How long will it take the tiro employees to wash a car together?

Answers

Answer:

60 minutes

Step-by-step explanation:

Given that Employee I can finish washing a car in 30 minutes. and

employee 2 can finish washing a car in 20 minutes.

Assuming that both will wath the car together after n minutes.

So, n must be the integral multiple of 30 as well as 20.

For niminum value of n, n must be the lowest common factor of 30 and 20.

[tex]\Rightarrow n = LCM(30,20) \\\\\Rightarrow n = 60.[/tex]

Hence, after 60 minutes, they will wash a care togethre.

Train one is going 75 m/s, train two is going 60 m/s, and train three is going 65 m/s.

Explanation:

For number one you could use the slope formula y2-y1/x2-x1, or you could simply just view it from the table that every second that’s passes the distance goes up another 75 meters. This means it would be 75 meters per second.

For the second one it’s a positive correlation that’s related meaning at every whole second (1,2,3...) the line will pass through it, so all you have to do is look at the left and see how much it’s going up by because we know it’s going up by the same amount each time.
