I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am pos

Aliun [14]

Answer:

2, 3, 5, 7, 11, 17, 19, 23

Step-by-step explanation:

The segment between - 15 and 25 has 40 numbers given by

25 - -15

= 25 + 15

= 40

Divided into 4 segments, each would contain 10 numbers such that the

1st segment is from -15 to -5 (which is -15 + 10)

2nd segment is from -5 to 5 (which is -5 + 10)

3rd segment is from 5 to 15 (which is 5 + 10)

4th segment is from 15 to 25 (which is 15 + 10)

Given that the unknown number is prime and positive this may be

2 or 3 or 5 from the 2nd segment

7 or 11 from the third segment

17 or 19 or 23 from the 4th segment

What's the perimeter of (-9,8) (-9,16) and (-17,8)

TiliK225 [7]

Answer:

16 + sqrt(128)

Step-by-step explanation:

find the lengths of all 3 sides:

the side from (-9,8) to (-9,16) will be 16-8=8 (x stays constant)

The side from (-9,8) to (-17,8) is 8 (-9- (-17)=8)

The side from (-9,16) to (-17,8) will be found from the distance formula

d=sqrt((-17-9)^2 + (8-16)^2))

= sqrt(128)

So the perimeter will be these 3 numbers added together

P=sqrt(128) + 8 + 8

= 16 + sqrt(128)

which can simplify to:

= 16 + 4sqrt(8)

= 16 + 8sqrt(2) = 8+ sqrt(2)

There are 1,200 students at roosevelt middle school. There are 700 boys at the school. What percentage of the students at roosev

Scilla [17]

Answer:

x=175/3

Step-by-step explanation:

700/1200=x/100

Simplify to 7/12

7/12=x/100

Multiply both sides by 100

7/12×100=x

Simplify 7/12 ×100 to 700/12

700/12=x

Simplify 700/12 to 175/3

175/3=x

Switch Sides x=175/3

hope that helps you

HELP WORTH 15 POINTS

Dafna1 [17]

Answer:

The total surface area is 140.4

Step-by-step explanation:

If we start with the larger surfaces on the top and bottom, we can find both of their surfaces by multiplying 4 by 6.5.

4*6.5=26. Since there are 2 of these surfaces, we can multiply 26 by 2 to get 52.

Then, we can find the surface area of the sides by multiplying 6.5 by 3.4.

6.5*3.4=22.1 Since there are four of these surfaces, we can multiply 22.1 by 4 to get 88.4.

Now, all we have to do is add them together.

52+88.4=140.4

The total surface area is 140.4

Hope this helps! :D
