Answer: A) 18.3 x 7 and D) 5.4 x 2.8
Step-by-step explanation:
A) 18.3 x 7 = 128.10
We can infer that 1 is in the tenths place.
B) 6.5 x 4.31 = 28.015
We can infer that 1 is not in the tenths place but rather the hundredths place.
C) 8.54 x 2.3 = 19.642
We can infer that 1 is not in the tenths place.
D) 5.4 x 2.8 = 15.12
We can infer that 1 is in the tenths place.
Answer:
91in^2
Step-by-step explanation:
SA of base = 7x7 = 49in^2
SA of each triangle = 1/2 x 7 x 3 = 10.5in^2
SA of all 4 triangles = 10.5 x 4 = 42in^2
SA Total = 49 + 42.= 91inch^2

Answer:
g = 14
Step-by-step explanation:
Given that f varies directly as g and inversely as h then the equation relating them is
f = ← k is the constant of variation
To find k use the condition f = - 12 when h = 4 and g = - 3, that is
- 12 = ( multiply both sides by 4 )
- 48 = - 3k ( divide both sides by - 3 )
16 = k
f = ← equation of variation
When f = 28 and h = 8 , then
28 = = 2g ( divide both sides by 2 )
g = 14
