Cross multiplication 13x -13 = 8x+12
combining like terms 13x -8x =12 +13
5x= 25 x= 5
x=5
Answer:
8
Step-by-step explanation:
77+50=127
180-127=53
7x-3=53
7x=53+3
7x=56
x=56/7
x=8
A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rate.
from the given table
when x=0 , y=20
when x= 1 , y = 30
We use this information to find exponential growth equation
General form of exponential growth is

WE plug in the given values and find out value of a and b
when x=0 , y=20

20 = a
Now we find out b
when x= 1 , y = 30

divide both sides by 20

So exponential function becomes

Now we find the insect population at the end of week 11
We plug in 11 for x


Round the answer to nearest whole number
1730 is the insect population at the end of week 11
Answer:
Group 13 to group 16
Step-by-step explanation:
Answer:
the answer b
Step-by-step explanation:
[surface area]=[area of 4 triangles sides]+[area of square base]
[area of square base]=24*24--------> 576 cm²
[area of one triangles side]
l=slant height
l²=16²+12²-------> l²=400-----------> l=20 cm
[area of one triangles side]=24*20/2--------> 240 cm²
[area of 4 triangles sides]=4*240----------> 960 cm²
[surface area]=[960]+[576]--------> 1536 cm²
