1. 7.8 x 10^3
2. 4.8 x 10^8
Step-by-step explanation:
Find 2r:
11 x 11 = 121
Multiply 2r with pi:
121 x 3.141592654 = 380.1327111
= 380.13 (Nearest hundredth)
I kind of forgot my 6th grade geometry, so I'm sorry if it is wrong.
Answer:
D = 9.80
Step-by-step explanation:
To find AB, we'll use the distance formula:
Distance Formula =
D =
D =
D =
D =
D = 9.80 (Upto 3 sfs)
The equation is 11x = 88. And Bianca had $8. Then the correct option is B.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Roberto had $88, which is eleven times as much money as Bianca had.
Then the amount of money Bianca had will be
Let Bianca's money be x.
Then we have
11x = $88
x = $8
Then the correct option is B.
