Answer:
Step-by-step explanation:
The rate if increase of side of square is 7cm/s
dL/dt=7
At what area is the area increasing
dA/dt=?
Areas of square is give to be 36cm²
Analysis
Let L be the length of each side of the square, a square has equal side.
Area of square is give as L²
Area=L²
L²=36
i.e L=√36
L=6cm
Therefore at t=0 L=6cm and A=36cm²
A=L²
dA/dL=2L
Given that, dL/dt=7
Multiply the two differential together
dA/dt= dA/dL × dL/dt
dA/dt= 2L × 7
dA/dt= 2×6×7
dA/dt= 84cm²/s
The rate of increase of the square is 84cm²/s
So, to find the constant we do this:
1.2n = 93,000,000
so n = 77500000So, with this constant, we multiply n with 0.86
0.86n = <span>66650000
So Venus is about </span><span>66,650,000 million miles away from the sun</span>
B. Identity property of division. Everything divided by 1 is itself.
Answer:
13 1/8 units³
Step-by-step explanation:
(see attached for reference)
Volume = Length x Width x Height
= 1 1/2 x 3 1/2 x 2 1/2 (convert to improper fractions)
= 3/2 x 7/2 x 5/2
= (3 x 7 x 5) / (2 x 2 x 2 )
= 105/8
= 13 1/8 units³
