Answer:
if im not mistaken its 121
Step-by-step explanation:
Answer:
SA = 484 cm²
Step-by-step explanation:
Surface area of the composite figure = surface area of the larger rectangular prism + (surface area of the smaller rectangular prism - base area of the smaller rectangular prism)
✔️Surface are of the larger rectangular prism = 2(LW + LH + WH)
L = 7 cm
W = 7 cm
H = 12 cm
S.A = 2(7*7 + 7*12 + 7*12) = 434 cm²
✔️Surface are of the smaller rectangular prism = 2(LW + LH + WH)
L = 7 cm
W = 2 cm
H = 2 cm
S.A = 2(7*2 + 7*2 + 2*2) = 64 cm²
✔️Base area of the smaller rectangular prism = L*W
L = 7 cm
W = 2 cm
Area = 7*2 = 14 cm²
✅Surface area of the composite figure = 434 + (64 - 14)
= 434 + 50
= 484 cm²
The given equation is ⇒ 100 - (1/2) x = 92
100 - (1/2) x = 92 ⇒ Add (-100) to both sides
-100 + 100 - (1/2) x = 92 - 100
∴ -(1/2) x = -8 ⇒ Multiply both sides by (-2)
∴ -2 * (-1/2) x = -8 x -2
∴ x = 16
So, the value of x will be equal 16
Answer:
12.5 or 12 1/2 Slices left
Step-by-step explanation:
30 divided by 6 or (1/6) is 5
So,
Violet ate 5
Sophie ate 5 (same amount)
30 divided by 5 or (1/5) is 7.5
so we add 5+5+7.5 = 17.5 and subtract it from 30 to get our left over slices which comes up to
12.5 or 12 and 1/2 slices
hope this helps
