 The number of students enrolled at a college is 13000 and grows 6% each year. Complete parts ​(a) through ​(e).

​a) The initial amount a is 13,000.

​b) The percent rate of change is 6%, so the growth factor b is 1 + 0.06 = 1.06.

​c) To find the number of students enrolled after one​ year, you calculate 13,000 · 1.06.  

​d) Complete the equation y = 13000 · 1.06^2 to find the number of students enrolled after x years.

​e) Use your equation to predict the number of students enrolled after 21 years.

 After 21 years, there will be 44,194 students enrolled.

Each shape is 1 whole. What fraction is represented by the shaded part of the model?
lubasha [3.4K]

Answer:

\frac{2}{1}

Step-by-step explanation:

Each shape is 1 whole.

In the given image, there are 4 parts in each shape.

The shaded part in the first shape is 4.

The fraction of the shaded part in the first shape

                                            =\frac{Number of shaded part}{Total part of the fraction}=\frac{4}{4}

The shaded part in the second shape is 4.

The fraction of the shaded part in the second shape

                                           =\frac{Number of shaded part}{Total part of the fraction}=\frac{4}{4}

The shaded part of the model =\frac{4}{4}+\frac{4}{4}

                                                  =\frac{1}{1}+\frac{1}{1}

                                                  = \frac{2}{1}

Hence, the fraction represented by the shaded part of the model is \frac{2}{1}.

Roger finished first.
2 2/3 is equal to 2 4/6. And then 2 and 4/6 is less than 2 and 5/6.

A
Gnesinka [82]

Answer:

A: 779 cm²

B: 1837 cm²

Step-by-step explanation:

For both problems, use the formula for surface area of a cylinder:

SA = 2πr² + 2πrh

2πr² is the two bases.

2πrh is the curved surface.

<u>PROBLEM A</u>

"the cylinder is 60 cm long" is h = 60.

If given diameter, you can find "r" by dividing it by 2. d = 2r

Given d = 4, then r = 2.

SA = 2πr² + 2πrh

SA = 2π2² + 2π2(60)

SA = 8π + 240π               Add

SA = 248π                       Exact answer

SA ≈ 779.114978             Answer on calculator

SA ≈ 779           Rounded answer

Remember to include the units.

The surface area is about 779 cm².

<u>PROBLEM B</u>

"80 cm long" h = 80.

"circumference of 22 cm". C = 22. Remember C = 2πr. Find "r".

C = 2πr

22 = 2πr

11 = πr

r ≈ 11/π

SA = 2πr² + 2πrh

SA = 2π(11/π)² + 22(80)       Substitute 2πr with the circumference.

SA ≈ 1837.030992            Answer on calculator

SA ≈ 1837               Rounded answer

Remember to include the units.

The surface area is about 1837 cm².
