Answer:
5 inches³
Step-by-step explanation:
2½ ÷ 5 = ½ (Length of the equal sized cube)
½×2 = 1 (width)
½ × 4 = 2 (height)
Volume of the right rectangular prism = L × W × H
2½ × 1 × 2 = 5 inches³
The radius of a sphere that has the surface area of 12.56 is r ≈1
(a−b)+a+(a+b)=45
⟹3a=45
a=15
a(a+b)=300
⟹15(15+b)=300
⟹225+15b=300
⟹15b=300−225
⟹15b15=7515
b=5
a−b=10⟹a=15⟹a+b=20
The three numbers are 10, 15, and 20.
Proof:
10+15+20=45✓
s = 71.6
____________
0.75 - 5/8s = 44
3/4 - 5/8s = 44
3/4 - 3/4 + 5/8s = 44 + 3/4
5/8s = 44 3/4
5/8s / 5/8 = 44 3/4 / 5/8
s= (179/4 / 5/8)
s= (179/4 * 8/5)
s= (179/1 * 2/5)
s= (358/5)
s= (350/5 + 8/5)
s= (70 + 8/5)
s= (70 + 1 + 3/5)
s= 71 3/5
s= 71.6
I checked this and its correct :P Sorry about the late answer, hope this helps!
First, solve the parenthesis
-8 + 6 = -2
-3[5 - (-2)]
Note that two negatives = one positive
-3[5 - (-2)] = -3[5 + 2]
Simplify. Solve the bracket
-3[5 + 2] = -3[8]
Simplify. Multiply to get the answer
-3 x 8 = -24
-24 is your answer
hope this helps
