Answer:

Just like multiplication is adding the same number multiple times, dividing can be described as subtracting the same number multiple times.

Ex:

4 x 3 = 12

4 + 4 + 4 = 12

8/2 = 4

8 -2 -2 = 4

Find the measurement of HI

Murljashka [212]

Answer: 15

Explanation: the triangle to the right is a dial action of the smaller triangle, therefore the triangles are similar. Since the sides of both triangles are corresponding if the corresponding side to JI is 5, and JI is 25 then it is a dialation by a multiple of 5. So since the corresponding side to HI is 3, HI is 15

A population of squirrels on an island has a carrying capacity of 350 individuals. If the maximum rate of increase is 1.0 per in

TiliK225 [7]

Answer:

The population growth rate is 59 squirrels per year.

Step-by-step explanation:

Given:

A population of squirrels on an island has a carrying capacity of 350 individuals. If the maximum rate of increase is 1.0 per individual per year and the population size is 275.

Now, to find the population growth rate.

Carrying capacity ( $K$ ) = 350.

Maximum rate ( $r_{max}$ ) = 1.0 per individual per year.

Population size ( $N$ ) = 275.

Now, to get the population growth rate we put formula:

$\frac{dN}{dT}= r_{max}\frac{K-N}{K}N$

$\frac{dN}{dT}=1.0\times \frac{350-275}{350}\times 275\\\\\frac{dN}{dT}=1.0\times \frac{75}{350}\times 275\\\\\frac{dN}{dT}=1.0\times 0.214\times 275\\\\\frac{dN}{dT}=58.85.$

So, rounding to nearest whole number of the population growth rate is 59 squirrels per year.

Therefore, the population growth rate is 59 squirrels per year.

PLEASE HELP! NO LINKS! TEN POINTS! please explain it if you can!

Nata [24]

I think the answer would be 112cm.

To find the area of the triangle you need to do basexheight divided by 2.
8x10 divided by 2 = 40

To find the area of the rectangle
12x6=72

40+72= 112cm

I’m not sure if it’s right but I hope this helps.
