Answer:
1.425.
Step-by-step explanation:
1 .425 is the only one which can be written as a fraction ( 1425/ 1000).
π is a non repeating decimal which goes on without bounds.
So is √50 (try entering it on your calculator).
√-4 : there is no real number whose square root is negative.
5:4 = 10:8 = length:width
10+8=18
162÷18= 9
9×10= 90
the length of the rectangle is D. 90 ft
Answer:
Step-by-step explanation:
3) Surface area of cube = 6a² where a is side of the cube.
a) a = 6 cm
Surface area of cube = 6 * 6*6 = 216 cm²
b) a = 4.5 cm
Surface area of cube = 6 * 4.5 * 4.5 = 121.5 cm²
4) Area of cuboid = A = 2(lb + bh + hl)
a) l = 10 cm ; h = 6 cm ; A = 376 cm²
A = 376
2(lb + bh + hl) = 376
2(10b + 6b + 60) = 376
2*( 16b + 60) = 376
2*16b + 2*60 = 376
32b + 120 = 376
32b = 376 - 120
32b = 256
b = 256 / 32
b = 8 cm
5) Surface area of cube = 150 cm²
6a² = 150
Divide both sides by 6
a² = 150/6
a² = 25 = 5*5
a = 5 cm
6) l = 15 cm ; b = 12 cm ; h = 10cm
Lidless. so area of top portion is not included
Surface area of lidless cuboid = 2(hb + hl) + lb
= 2*(10*12 + 10*15) + (15*12)
= 2*(120 + 150) + 180
= 2* 270 + 180
= 540 + 180
= 720 cm²
Answer:
256
Step-by-step explanation:
so the basic problem is 192 divided by 3/4, so you flip the second fraction around. So the problem is now 192*4/3.
SIMPLIFY
192/3 is 64, and then you times 64 to 4, which equals 256
