Answer:

C

Step-by-step explanation:hope this helps have a great day =D

There are two equation of the system

(1) The perimeter

    2(w + l) = p

    2(w + l) = 86

(2) The length and the width

     2w = l + 2

From the second equation

2w = l + 2

l + 2 = 2w

l = 2w - 2

Subtitute l with 2w - 2 in the first equation to find the width

2(w + l) = 86

2(w + 2w - 2) = 86

2(3w - 2) = 86

6w - 4 = 86

6w = 90

w = 15

Now, find the length by subtituting w with 15

l = 2w - 2

l = 2(15) - 2

l = 30 - 2

l = 28

The dimension of the rectangle

length = 28 cm

width = 15 cm

Step-by-step explanation:

Pyramid

1/2 * 12 * 15

6 * 15 = 90

90 * 4 = 360cm

Cube

12 * 12 = 144

144 * 4 = 576cm

576 + 360 =

936 cm² of paint

Answer: 8/100

Step-by-step explanation: I converted 5/10 in 50/100 and subtracted 50 from 58 and got 8 so the answer is 8/100.

Answer:

1. 2:5

2. 110 (the total degree of a triangle is 180 so it would be 40+30+x=180)

3. 37 (It's a right angle, 90 degrees so it would be 90-53=x)

Answer:

It should be about 40 or 50 degrees.

i dont know I used a protractor

Answer:

1stB = 2nd H

2ndB = 3rd H

3rdB  = 1st H

Step-by-step explanation:

1stB = 2nd H

2ndB = 3rd H

3rdB  = 1st H

As they are right angle triangles and 2 lines are perpendicular.

To find height of any shape we look for perpendicular line this also applies to segments.

Segments as seen below can only be cut off areas of a circle by either a chord touches line as shown second picture, or a secant which is a perpendicular use line . and crosses the line of the circle but is not shown in picture only the chord is.

Secant line still forms a segment but is only used usually with overlapping shapes some which are parallel in geometry solving for tangents or shading.

Answer:

1stB = 2nd H

2ndB = 3rd H

3rdB  = 1st H

Answer:

9x + 150 = 226.50

Step-by-step explanation:

Devon makes $9 per hour. So, that signalizes "9x" (x representing the amount of hours he worked)

$150 represents how much he made one night, so you would add that to 9x. (9x + 150)

Finally, it gives you the total amount: 226.50

In conclusion, your equation should be: 9x + 150 = 226.50

Answer: The answer is answer (C) sorry if I am wrong

Step-by-step explanation:

5x + 38 is less than or equal to 8 - 20x.25x is less than or equal to -30.x is less than or equal to -(6/5).Hence, the correct answer is (C).

Answer:

y=1/2x+5

Step-by-step explanation:

m= change in y over change in x;  the y-value is going up by 1 every time;  the x-value is going up by 2; change in x/change in y is 1/2

b= whatever value the y is when x is 0 is your y-intercept; when x is 0 y is 5

Answer:

I Believe the answer would be $16 x 128%

Answer:

1. x>18    2.x<-18     3. x>21     4. x>-7     5. x<2     6. x>-2     7. x<12    8.x<-6

Step-by-step explanation:

1. x/2>9 Pretend the inequality is an equal sign...

x/2=9 *2            x=18

If x>18; 20>18

20/2 = 10

10>9 so it works

If x<18      10<18

10/2 = 5

5<9 so it dosent

2. x/-2>9

x/-2=9

x=-18

If x>-18

0>-18

0/-2=0

0<9 so it doesent work.

x<-18; x=-20

-20/-2=10

10>9 So it works

3. x-7>14 --> x-7=14 ---> x=21

If x>21; x=22 --> 22-7=15; 15>14 (it works)

If x<21; x=20 --> 20-7=13; 13<14 (so it does not work)

4. x-7>-14 --> x-7=-14 --> x=-7

If x>-7; x=0 ---> 0-7=-7 --> -7>14 (so it works)

If x<-7; x=-10 ---> -10-7=-17 --> -17<14 (so it does not work)

5. 5x<10 --> 5x=10 --> x=2

If x>2 x=3 --> 5*3=15 15>10 (does not)

If x<2 x=1 --> 5*1=5 5<10 (works)

6. -5x<10 -5x=10  x=-2

If x<-2 x=-3 -3*5=-15 -15<10 (no)

If x>-2 x=0 5*0=0 0<10 (works)

7. x-3<9  x-3=9 x=12

if x>12 x=13 13-3=10 10>9

If x<12 x=10 10-3=7 7<9 (works)

8. x-3<-9 x-3=-9   x=-6

if x>-6; x=13; 13-3=10 10>-9

if x<-6 x=-10 -10-3=-13   -13<-9 (works)
