From 4 p.m to 8 p.m, there are 4 hours. Each hour is composed of 60 minutes. This means that the total number of minutes is equal to 240. Thus, we determine the ratio of her time in doing the homework by dividing 10 minutes by 240 minutes, giving us the answer of 10:240 equal to 1:24.

A car is traveling at a constant speed of 60 miles per hour. How many feet does it travel in 10 seconds?
Nat2105 [25]

Answer:

880 ft.

Step-by-step explanation:

<em>First! We have to establish how many feet the car travels per hour. </em>

60 <em>(number of miles per hour)</em> x 5280 <em>(number of feet in a mile) </em>= 316,800 <em>(number of feet in an hour)</em>

<em>Next, since we know that there are 60 minutes in an hour we are going to divide our "number of feet in an hour" by 60 to get the "number of feet in a minute"</em>

316,800 ÷ 60 = 5280

<em>Once again, we are going to divide our "number of feet in a minute" by 60 to get the "number of feet per second".</em>

5280 ÷ 60 = 88

<em>Finally! We will multiple our "number of feet per second" by 10 to get how many feet the car can travel in 10 seconds.</em>

88 × 10 = 880

<em>So! Our car can travel 880 feet in 10 seconds.</em>

Hope this Helps! :)

In the diagram below of parallelogram ABCD with diagonals AC and BD, m∠1=45° and m∠DCB=120°.Whatisthemeasureof∠2?
bixtya [17]

Answer:

15degrees

Step-by-step explanation:

From the given diagram

<1+<2 + <DCB = 180

<1+<2+120 = 180

<1+<2 = 180 - 120

<1+<2 = 60

<2 = 60 - <1

<2 = 60 - 45

<2 = 15degrees

Hence the measure <2 is 15degree

Determine whether the given segments have the same length. Complete the justification of your answer,
Ratling [72]

Answer:

No does not contain the same length

Step-by-step explanation:

Given that

A(-4,2) , B (1,4), C (2, -1)

Now

AB would be

= \sqrt{(1-(-4))^2 + (4-2)^2} \\\\= \sqrt{29}

And, BC is

= \sqrt{(2-1)^2 + 1-(-4))^2} \\\\= \sqrt{26}

As we can see that the AB and BC are not equaled

So,

AB ≠ BC

Due to the different length

Therefore they do not contains the same length

We simply applied the distance formula due to which the length could be determined and the same is to be considered
