Answer: 32 students
Step-by-step explanation: 8 x 4 = 32
If K is midpoint of JL then JK = 0.5JL
JL = 4x - 2; JK = 7
The equation:
0.5(4x - 2) = 7
2x - 1 = 7 |add 1 to both sides
2x = 8 |divide both sides by 2
<u>x = 4</u>
<u>JL</u> = 4(4) - 2 = 16 - 2 = <u>14</u>
<u>KL</u> = JK =<u> 7</u>
Answer:
45
Step-by-step explanation:
15% of 100 = 15
15 x 3 = 45
Answer: 480 units^2
IN DEPTH EXPLANATION TO HELP YOU FOR FUTURE PROBLEMS:
Front:
b*h/2 = sa
12*5/2 = 30
Front = 30 units^2
Back:
b*h/2 = sa
12*5/2 = 30
Back = 30 units^2
Right:
w*l = sa
14*13 = 182 units^2
Right: 182 units*2
(figures out the length by using
pythagorean theorem)
Left:
w*l = sa
5*14 = 70 units^2
Left: 70 units^2
Bottom:
w*l = sa
12*14 = 168 units^2
ADD ALL THE UNITS:
168 + 70 + 182 + 30 + 30 = 480
Answer:
The height of the tomato soup can is 2.6 in.
Step-by-step explanation:
"The can of chicken noodle soup has a height of 4 inches and a radius of 2 inches."
We can find the volume of this can.
V = pi r² h
V = 3.14 * (2 in.)² * (4 in.)
V = 50.24 in.³
"The can of tomato soup has the same volume, but a radius of 2.5 inches."
Now we know the volume of the can, so we can find the height, h.
V = pi r² h
50.24 in.³ = 3.14 * (2.5 in.)² * h
50.24 in.³ = 19.625 in.² * h
h = (50.24 in.³)/(19.625 in.²)
h = 2.56 in.
Answer: The height of the tomato soup can is 2.6 in.
