Travis will complete a 60-mile trip in _____ hours?

Natasha2012 [34]

Answer: 2.5 hours is the answer

Step-by-step explanation:

It took Travis 2.5 hours to complete 3/4 of his trip. To find the average speed, we need to find his speed during 3/4 of the trip and then the 52.5 miles.

So you know that 52.5 is 1/4 of his total trip. That means if we multiply that by 3, that's how many miles he traveled in 2.5hrs. (157.5)

To calculate speed, divide distance by time.

For 3/4 of his trip (157.5), it took him 2.5 hours.

157.5/2.5 = 63mph

For the remaining 52.5 miles, it took him an hour.

52.5/1 = 52.5mph

Now average those two speeds to get the average speed for the whole trip.

(63+52.5)/2= 57.6mph

I need help asap:):):)

Elena L [17]

Answer:

10 feet

Step-by-step explanation:

18 × 2 = 36

56 - 36 = 20

20 ÷ 2 = 10

To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56

Find the sides of a triangle if two of its sides are equal, the third side is 1 1 3 cm longer than the others, and its perimeter

Helga [31]

Answer: $137\dfrac{1}{3}\ cm,\ 137\dfrac{1}{3}\ cm,\ 250\dfrac{1}{3}\ cm$

Step-by-step explanation:

Let x be the equal sides of the triangle .

The , the third side would be x+113 cm.

The perimeter is the sum of all sides of a triangle.

So , The perimeter of triangle would be x+x+(x+113)= 3x+113 --------(1)

Since , it is given that the perimeter of triangle is 525. -----(2)

So from (1) and (2) , we have

$3x+113=525\\\\ 3x=525-113=412\\\\ x=\dfrac{412}{3}=137\dfrac{1}{3}$

Then, third side = $137\dfrac{1}{3}+113=250\dfrac{1}{3}\ cm$

Hence , the sides of a triangle are: $137\dfrac{1}{3}\ cm,\ 137\dfrac{1}{3}\ cm,\ 250\dfrac{1}{3}\ cm$

Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.

Darya [45]

Answer:

see the explanation

Step-by-step explanation:

we have

$5x-2y=10$

<em>Find the x-intercept</em>

Remember that the x-intercept is the value of x when the value of y is equal to zero

For y=0

$5x-2(0)=10\\5x=10\\x=2$

the x-intercept is the point (2,0)

<em>Find the y-intercept</em>

Remember that the y-intercept is the value of y when the value of x is equal to zero

For x=0

$5(0)-2y=10\\-2y=10\\y=-5$

the y-intercept is the point (0,-5)

using a graphing tool

Plot the intercepts and connect them to graph the line
