Find the perimeter and the area of jacobs pool shown in the diagram below be sure to show all your work
Ksenya-84 [330]

Answer: Perimeter- 88m  Area- 207sqm

Step-by-step explanation: To find the perimeter, you have to sort of split the shape into simple boxes. To find the line at the bottom, you have to add 18+11 because you can see that they match the line in the bottom. 18+11=29. You then have to find the P of the left. With the same method, you do 6+9, which equals 15. You add all of the sides together to get 88m. To find Area, you split the boxes into 2 smaller boxes. you then do 18x6 to get 108 for the top box. And 11x9 which equals 99. You add them together to get the area, 207! Hope that makes sense!!!

The student population at the University is currently 400. The expected annual rate of increase is predicted to be 0.02. What wi
kotegsom [21]

Answer:

The population of the students at the University after 5 years is <u>442</u>.

Step-by-step explanation:

Given:

Current population of students is, P_o=400

Growth rate is, r=0.02

Time after which population is needed is, t=5\ years

Let 'P' be the population after 't' years.

Population growth is an exponential growth and the equation to determine the population after 't' years is given as:

P=P_oe^{rt}

Now, plug in 400 for P_o, 0.02 for 'r', 5 for 't' and solve for 'P'. This gives,

P=(400)e^{0.02\times 5}\\\\P=400\times e^{0.1}\\\\P=400\times 1.1052\\\\P=442

Therefore, the population of the students at the University after 5 years is 442.

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
