nataly862011 [7]

Step-by-step explanation:

write a formula that models this.

9.30x = money earned

If he works 2 hours, he'll get $9.30 times (2)

and so on. so you write and solve

9.30(1), 9.30(5), 9.30(8)

for the second part you want to substitute 180 for the amount earned which will become

9.30x = 180 then you solve for x

During two years, the population of birds of an island became 7 times more than before. If the first year increase in the popula

9966 [12]

The percent increase of the second year was 85.71%

Step-by-step explanation:

The exponential growth formula is y=a(1+r)^x

where;

y=population after x years

a=original population

r=growth rate as a decimal

x=number of time interval that have passed

Let starting population be p

The first year increase in the population was 40% this means;

r=0.4 , x=1 and a=p thus the equation will be

y=p(1+0.4)^1 ⇒⇒y=1.4 p

In the second year the population of birds of an island became 7 times more than before which is 7p

7p= 7*1.4p= 9.8p

Increase will be;

9.8p-1.4p=8.4

% increase will be;

8.4/9.8 *100 =85.71%

Help! Best answer gets brainliest

julsineya [31]

Answer:

7.9

Step-by-step explanation:

the first thing to do is find the second projection.

16-7 = 9

than we can use a proportion to find BD

7 : BD = BD : 9

BD = √9 x 7 = √63 = 7.9

we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2
