Answer:

2.8284

Step-by-step explanation:

Input Data :

Point 1(xA,yA)(xA,yA) = (4, 10)

Point 2(xB,yB)(xB,yB) = (6, 12)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(6−4)2+(12−10)2(6-4)2+(12-10)2

= √22+2222+22

= √4+44+4

= √88 = 2.8284

Distance between points (4, 10) and (6, 12) is 2.8284

There are 42 students 21 are in 7th grade 14 are in 8th 7 are in ninth whats the probability of an eighth grader winning
Varvara68 [4.7K]

Answer:

The probability of an eighth grader winning is 1/3

Total no. of students = 42

Number of students in 7th grade = 21

Number of students in 8th grade = 14

Number of students in 9th grade = 7

Probability of event = \frac{\text{Favorable outcomes}}{\text{Total outcomes}}

So,the probability of an eighth grader winning= \frac{14}{42}=\frac{2}{6}=\frac{1}{3}

Hence The probability of an eighth grader winning is 1/3

Solve the System using elimination. <br><br> 5x-2y=15<br> 7x+7y=-28
steposvetlana [31]

Answer:

x=1 y=-5

Step-by-step explanation:

7(5x-2y=15) --->      35x-14y=105

2(7x+7y=-28) -->  + <u>14x+14y=-56</u>

                               49x=49  --->x=1

5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5

Kat runs 3 1/2 miles in 3/4 of an hour. What is her unit rate? Use fractions to find out and express your answer as a mixed numb
Drupady [299]

Answer:

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=

12 miles

1 hour = 12 miles hour = 12 miles per hour

The maximum weight on a roller coaster is 400 pounds. If your friend weighs 120 pounds, what is the most that you can weigh so y
wolverine [178]
The maximum weight on a roller coaster is 400 pounds (Max = 400).
If your friend weighs 120 pounds (y = 120), what is the most you can weigh so you can ride together (x + y < 400).

x + 120 <_ 400.
y = 120

Subtract 120 from both sides.

x <_ 280.

You can weigh at most 280 pounds (x <_ 280).

I  hope this helps!
