Answer:
the perimeter of the Pentagon is 2.75cm
Step-by-step explanation:
add each side together in decimal form
<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1
</span>
Answer:
Step-by-step explanation:
<u>Given equation</u>
- f(t) = 2^(kt)
- f - number of cells, t - number of months, k- coefficient
<u>We got 32 cells in the first month. It means:</u>
<u>Using these numbers we can find the coefficient k:</u>
- 32 = 2^(k*1)
- 2^5 = 2^k
- k = 5
<u>Then the equation becomes:</u>
<u>Average time is 9 months, we can calculate the number of cells:</u>
- f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13
Answer:
The party will cost 28.125 dollars.
Step-by-step explanation:
Because to find how much each person costs you would have to take 22.50 divided by 4 to get 5.625, then do 5.625 times 5 to get 28.125 as your answer.
for 64527 in scientific notation will be:
for 0.325x10^-2 will be:
for 0.0007654 x 10^0 will be:
For 18432 x 10^8 will be:
