Answer:
d≈56.01cm
A Area
2464
cm²
Using the formulas
A=πr2
d=2r
Solving ford
d=2A
π=2·2464
π≈56.01127cm
Step-by-step explanation:
Answer:
256
Step-by-step explanation:
since the the path surounds both sides of the garden you have to add 2 x instead of just x
let me show you what i mean. 10=garden width and 3=path width=x
since it is a square, we can calculate the area by taking one side and squaring it so you get (10+2x)^2 which is 16^2 since x is 3, the width of the garden
to do simaler problems just use thei formula (garden length+2path length)^2 or (garden length+2path length)times(garden length+2path length)
Answer:
x = - 9
Step-by-step explanation:
Given
3x + 2 = 2x - 7 ( subtract 2x from both sides )
x + 2 = - 7 ( subtract 2 from both sides )
x = - 9
Answer:
60 hand shakes.
Step-by-step explanation:
We have been given that there are 6 married couples at a party.
This means there are 12 people in total.
We know that number of handshakes for n people is given by formula 
.
We are also told that at the start of the party every person shakes hands once with every other person except his or her spouse.
So formula for this problem would be 
or 
.
Since total numbers of people is party is 12, so we will get:
Therefore, there will be 60 hand shakes at the party.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.
