Answer: 201.06 cm^2
Step-by-step explanation: We're just solving for the area of a circle. A = pi•r^2. The diameter is 16 which is 2r so r = 8. 8^2 • pi = 64pi = 201.06 (rounded to 2 decimals)
Answer:
The number = 45
Step-by-step explanation:
Let the 10s digit = x
Let the units digit = y
10*x + y = 5(x + y) Start here: remove the brackets
10*x + y + 9 = 10y + x Subtract y and 10x from both sides
Using the first equation
10x + y = 5x + 5y
5x + y - 5y = 0
5x - 4y = 0
5x = 4y
y = 5/4x
From the second equation
9 = 9y - 9x
1 = y - x Substitute y = 5/4 x
1 = 5/4x - x
1 = 1/4 x
x = 4
y = 5/4 * 4
y = 5.
Ha. That looks alot like i-ready. (i-ready sucks butt.)
But the horror that is i-ready aside, your answer is the third one : The proportion of grandparents that feel safe entering their account information online is 0.32.
32% converted to a decimal is 0.32, and 68% converted to a decimal is 0.68. That would mean that the proportion for grandparents that feel safe doing so is 0.32, and the number of grandparents that don't feel safe doing so is 0.68.

Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, the equation would be K=144/18
If you're also going to find the number of kids, you would get 144/18 which is 8 {including Jim}.
