Answer:
40 feet
Step-by-step explanation:
x/20=6/3
3x/3=120/3
x=40 feet
Answer:
x = -1
Step-by-step explanation:
y + 2x = -1
Subtract 2x from both sides;
y = -2x - 1
y = 3x + 4
-2x - 1 = 3x + 4
Subtract 3x from both sides;
-5x - 1 = 4
Add 1 to both sides;
-5x = 5
Divide both sides by -5
x = -1
Answer:
2 for $0.25
Step-by-step explanation:
1.10/ 6= .20 (rounding)
1.00/ 5= .20
0.85/ 4= .21
0.25/ 2= .13 (rounding)
<u>Given</u><u>:</u>
- Area of rectangular prism ( cuboid ) = 448 cm²
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u>
Find the height, h ?
<u>Formula </u><u>used </u><u>:</u>
Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )
<u>Solution</u><u>:</u>
We know that that,
Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )
=> 448 = 2 ( 14 × 6 + 6 × h + h × 14 )
=> 448 = 2 ( 84 + 6h + 14h )
=> 448 = 2 ( 84 + 20h )
=> 448 = 168 + 40h
=> 40h = 448 - 168
=> 40h = 280
=> h = 280/40
=> h = 7 cm
