Use the circular formula and divide the volume by 2
Step-by-step explanation:
Answer:
(-6,4)
Step-by-step explanation:
1/3x − 2 = x + 2 is obtained by equating the following two functions:
y = (⅓)x - 2
y = x + 2
Graph:
Draw two straight lines
1) joining (0,-2) and (6,0)
2) joining (0,2) and (-2,0)
On the graph, you'll see that the above two lines intersect at: (-6,4)
Hence the solution is (-6,4)
Answer:
See below
Step-by-step explanation:
13*1 = 13
13*2 = 26
13*3 = 39
13*4 = 52
13*5 = 65
13*6 = 78
13*7 = 91
13*8 = 104
13*9 = 117
13*10 = 130
Basically you just count how many there is of each.
So the answers would be:
Pentagon = 1
Triangle = 7
Moon = 1
Hope this helps!
Answer:
The person invested $3500 at 7% and $2500 at 5%
Step-by-step explanation:
We can say that
because the investment is equal both in one as in another, where x is the income from the investment.
Solving the equation we have:

Then to get the incomes:
At 7%: 
And at 5%: 
Finally we can demonstrate the answer because the income at 7% + income at 5% are 3500+2500=$6000
