Answer:

The slope is 4.

Step-by-step explanation:

In order to find this without graphing it you can put it in y-y/x-x form. So you subtract the y points on the top. 5-25=-20. then you subtract the x points -2-3=-5 so then you divide -20 by -5 since they are both a negative they become a positive and 20/5=4 so your slope is 4/1.

I HAVE ASKED THIS TWICE NOW YOU GUYS!! SOMEONE PLEASE HELP ME I REALLY NEED HELP PLEASE THIS IS A VERY IMPORTANT TEST I WILL GIV
lubasha [3.4K]
Ok so 12 in. = 1ft
210 in = 17.5 ft
35 in = about 2.9 ft
17.5/2.9 = approximately 6 ft.
I think the answer is 6 ft
At the same time 210/35 = 6, which would make the length 6 in., because area equals base times height, so you just divide, which would make it 1/2ft.
I would go with 6 in.

masha68 [24]

Answer:

A. 2⅓ and D.1

Step-by-step explanation:

We are required to select the values of x that makes the inequality x>½ true.

A. 2⅓

B. 0

C.-1½

D. 1

E.-¾

Options C and E are negative numbers and are therefore less than the positive number ½.

Option B(i.e. 0) is also less than ½ or 0.5 and therefore do not satisfy the inequality given.

Options A and D are greater than ½ and therefore satisfies the inequality given.

What is the distance to the earth's horizon from
shepuryov [24]

Answer:   216.2 miles

Step-by-step explanation:

Alright, lets get started.

As the diagram shows, the line from point P is tangent to earth's curvature.

It means it is making right angle.

So the triangle formed will be  right triangle.

Hence we can use Pythagorean theorem in it.

So from point P to center of earth, it will be hypotenuse of triangle.

c^2=a^2+b^2

(3959+5.9)^2=3959^2+x^2

3964.9^2=3959^2+x^2

15720432.01=15673681+x^2

x^2=46751.01

taking square root, the x will be :

x = 216.2

hence the value of x is 216.2 miles.   :   Answer

Hope it will help :)

A card is picked at random from the following set: 6, 7, 8, 9. What is P (9)? Write your answer as a percentage.
lozanna [386]

Answer:

25% = (p) 1/4 = picking a number 9.

(p) 1/4 = 0.25 (results getting a number more than 8 or just getting 9

This is add rule from the 4 card set.

1/4 + 0 + 0 + 0 = 1/4

Because each (P) is equal and shows (P); 1/4  

there are 1 event so 1/4 + 0= 1/4 = 0.25%

Step-by-step explanation:

0.25 x 100 = 25%

1. Solve the system by substitution- 2x+y=-11, 3x-4y=11.
Maksim231197 [3]
In the first equation, moving 2x over gives "y = -2x-11". Placing this into the second equation gives "3x - 4(-2x-11) = 11", or "3x+8x+44 = 11", which can be reduced to "11x= -33" or "x = -3". Replacing the "x" with -3 in the first equation gives "-6 + y = -11" or "y = -5". This gives a solution of (-3, -5), or answer C.
