What is the answer?

Mathematics
1 answer:
lesantik [10]3 years ago
8 0

Answer: D

Step-by-step explanation:

First, you have to multiply 2 by 7, because m=7. Then you have to multiply7 by -1 because n=-1. So on the top, you will get 14- -7. Now on the bottom, its just 7 + -1, which is 6. When there is a minus sign and a negative sign next to each other, for example 14- -7, you have to add. Next, you had 14 and 7 to get 21. Finally, you have to divide 21/6 and you get 3.5, which as a fraction is 7/2.

hope this helps :)

A Square has the vertices at (-2,6) (6,1) (1,-7) (-7,-2). At what point do the diagonals of the square intercect
DerKrebs [107]

Answer: At point (-\frac{1}{2},-\frac{1}{2})

Step-by-step explanation: <u>Diagonal</u> is a line uniting two opposite points. In a square, the diagonals intersect in a 90° and bisect each other, i.e., divides each diagonal into two segments of the same length.

In other words, the diagonals of a square meet at their midpoint, which is found as the following:

(x,y) = (\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})

The opposite vertices of the given square are (-2,6) and (1,-7).

So, the intersection is

(x,y) = (\frac{-2+1}{2} ,\frac{6-7}{2})

(x,y) = (-\frac{1}{2},-\frac{1}{2} )

The diagonals of square with vertices (-2,6)(6,1)(1,-7)(-7,-2) intersect at point (-\frac{1}{2},-\frac{1}{2} ).

I use the formula and apparently I might be doing it wrong
stich3 [128]
Distance = 30 mi
Speed = 45 mi/h
We know that Distance = Speed x Time OR Time = Distance/Speed

Time to go to the site: T = 30/45 = 0.66667 Hour. Multiply by 60 to get it in minutes: 0.66667 x 60 = 39.9999 ≈ 40 minutes

To come back he also spent the same time or 40 minutes
 To and Fro = 80 minutes or 1 H 20 minutes
