Step-by-step explanation:

37)

Perimeter of a circle = 2 π r

It is given that the radius is 4 yards

Substitute this into the formula

2 π 4

Substitute 3.14 in for π

2(3.14) * 4

6.28 *4

25.12

Rounded to the nearest tenth of a yard:

25.1 C

38)

Yvette's salary = s

Increased by 4.5%

4.5% = 0.045

Current salary: s + 0.045s D

39)

Length = = 4.75

Width = 4.75 ÷ 2 = 2.375

Area = (2 * Length) + (2 * Width)

Substitute in length and width values

Area = (2 * 4.75) + (2 * 2.375)

Area = 9.5 + 4.75

Area = 14.25 inches = $14\frac{1}{4}$ inches

Hope this helps :)

For n = 3, what are the possible sublevels?

PilotLPTM [1.2K]

N represents the quantum number. for n = 3, there are 3 possible sublevels that are 3s, 3p and 3d.
There are four sublevels that are s, p, d and f. In s subshell or sublevel there is 1 orbital, in p sublevel there is 3 orbitals, in d sublevel there is 5 orbitals and in d sublevel there is 7 orbitals.
And there are 2, 6, 10 and 14 maximum number of electrons in s, p, d and f sublevels respectively.

Jacqueline reach the end of the trail in two hours and 15 minutes. Write the amount of hours he spent on the trail as a mixed nu

LenaWriter [7]

You would keep the 2 hour for the whole number of the mixed number and then, make the minutes (15) as a fraction with 60, and divide them both by 20. that is just for the mixed number.

Substitute the given number into the equation

Sum = 180(15-2)

Solve brackets

180(13)

Which is equal to 2340

So, the sum of interior angles is 2340 degrees

A flagpole casts a shadow 16 feet long.

Triss [41]

Step-by-step explanation:

Since Shanika is standing near the pole, we can safely assume that the triangle formed by Shanika and her shadow is a smaller version of the triangle formed by the pole and its shadow.

By similar triangles:

$\frac{x \: of \: pole}{y \: of \: pole} = \frac{x \: of \: shanika}{y \: of \: shanika} \\ \frac{16}{ height \: of \: pole} = \frac{4}{5} \\ 16(5) = 4 \times height \: of \: pole \\ height \: of \: pole = \frac{80}{4} \\ = 20$

The height of the pole is 20ft.
