A High School soccer team is going to Columbus, Ohio to see a professional soccer game. A coordinate grid is superimposed on the
finlep [7]

Answer: The coordinate are

( 5 , 2.5 )

Distance = 5

Step-by-step explanation:

The coordinates of the rest stop will be the mid point between the high school is at point (3, 4) and the stadium in Columbus at point (7, 1).

Mid point = (X1 +X2)/2 , (Y1+Y2)/2

(3+7)/2 , (4+1)/2 = ( 5 , 2.5 )

The approximate distance between the high school and the stadium will be

D^2 = (7-3)^2 +( 4-1)^2

Where D = distance

D^2 = 4^2 + 3^2

D = 5

The ratio of the measures of the three angles is 2:6:7. Find the measure of each angle of the triangle.
Tpy6a [65]
Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)

Prove this conjecture
steposvetlana [31]

Answer:

See explanation

Step-by-step explanation:

Consider the natural number n(n+1)(n+2).

If n is the natural number, then n+1, \ n+2 are next two natural numbers, so numbers n,\ n+1 and n+2 are three consecutive numbers.

Given three consecutive natural numbers, one of them is always even number and one of them is always multiple of 3, so the product

n(n+1)(n+2)

is divisible by 6.

Please help asap! Will give brainliest!
olga nikolaevna [1]

Answer:

c

Step-by-step explanation:

when 2 lines are perpendicular, the product of their gradients will give you -1 thus the gradient of the equation is

2 x m = -1

m = -1/2

and since it will pass thru point (-3, 7)

thus it will results in (x+3) and (y-7)
