Answer:

It will take 2.5 hours.

Step-by-step explanation:

We know that,

Speed = \frac{Distance}{Time}

If distance is 80 miles and time taken is 2 hours,

Then,

Speed = \frac{80}{2}=40\text{ miles per hour }

Here sara is travelling with the constant speed which is 40 miles per hour,

If distance = 100 miles,

Hence, the time taken by her = \frac{Distance}{Speed}

=\frac{100}{40}=2.5\text{ hours}

It will be 80/2 and 0/10 you will have to multiply 10*80/2=4000

Find the inverse of the given relation. {(9, –14), (–7, 4), (6, –8)}
Law Incorporation [45]

Answer:

{(-14,9),(4,-7),(-8,6)}.

Step-by-step explanation:

To find the inverse you just swap x and y.

So if (a,b) is a point on the relation then (b,a) is on it's inverse.

So the inverse of {(9, –14), (–7, 4), (6, –8)} is:

{(-14,9),(4,-7),(-8,6)}.

Find the distance between<br> (-1, - 3) and (8, – 3).
dimaraw [331]

Answer: d (A,B) = 9

Step-by-step explanation: d(A,B) = √(xB - xA)^2 + (yB - yA)^2

                                              d(A,B) = √(8-(-1))^2 + (-3 - (-3))^2

                                              d(A,B) = √81 + 0    

                                              d(A,B) = 9

Fill in the blank.
Marrrta [24]

Question:

Fill in the blank.

23 x 6 = (20 + 3) * 6

23 x 6 = _ + (3x6)

Options

20 * 6

20 * 3

20 * 5

Answer:

20 * 6

Step-by-step explanation:

Given

Expression 1:  23 * 6 = (20 + 3) * 6

Expression 2:  23 * 6 = __ + (3 * 6)

Required

Fill in the blank

From Expression 1

23 * 6 = (20 + 3)*6

Using Distributive Property; The expression becomes

23 * 6 = 20 * 6 + 3 * 6

23 * 6 = (20 * 6) + (3 * 6)

By Comparing this with expression 2

23 * 6 = __ + (3 * 6)

The blank position is occupied by 20 * 6.

Hence, the correct option that fills the missing blank correctly is 20 * 6
