Find the diagonal of a television screen 30 inches wide by 35 inches tall.
marin [14]

Answer:

46.1 in

Step-by-step explanation:

Given data

Width= 30in

Height= 35in

To find the diagonal, we have to use the Pythagoras theorem

z^2= x^2+y^2

z^2= 30^2+ 35^2

z^2= 900+1225

z^2= 2125

z= √2125

z= 46.09

Hence the diagonal of the TV is 46.1 in

What would -2 - (-7) be? And how would you do that
zavuch27 [327]

Answer:

5

Step-by-step explanation:

Okay, so adding negative numbers can get very tricky, but I think I can help

Since there are two negative signs next to each other, they both cancel out and become positive so instead you get

-2+7

And if you do this with a number line, if you start and negative 2 and keep going right 7 times, you get 5

I hope I helped! I know negative numbers can be really difficult, but once you get the hang of it I bet you'll be great!

n parallelogram LMNO, MP = 21 m, LP = (y + 3) m, NP = (3y – 1) m, and OP = (2x – 1) m. What are the values of x and y? x = 10, y
seropon [69]

Answer:

The value of x = 11  and y = 2

Step-by-step explanation:

Given : parallelogram LMNO, MP = 21 m, LP = (y + 3) m, NP = (3y – 1) m, and OP = (2x – 1) m.

We have to find values of x and y.

Let P be the point of intersection of diagonals OM and LN.

In a parallelogram diagonal  bisects at right angles  and point of intersection divide diagonal in equal parts.

Thus, OP = MP and LP = PN

OP = MP , substitute the values, we get,

(2x-1) =  21

⇒ 2x = 22

⇒  x = 11

LP = PN , substitute the values, we get,

y + 3 = 3y -1

⇒  3y - y = 4

⇒  2y = 4

⇒ y = 2  

Thus, the value of x = 11  and y = 2
