Answer:

29,225.78 m^3 to the nearest hundredth.

134.4 m^3.

Step-by-step explanation:

The building:

The area of the floor = area of the square + 3/4 * area of the circle

= 22^2 + 3/4 π 11^2.

The volume of the building =

38 * (22^2 + 3/4 π 11^2)

= 29,225.78 m^3.

The greenhouse:

The sides consist of 2 pairs of trapezoids.

Area of a side = 2 * (0.6/2)(0.7 + 2.1) + 2 * (1.4/2)(2.1 + 2.7)

The length is 16 m so:

Volume = 16 * [ 2 * (0.6/2)(0.7 + 2.1) + 2 * (1.4/2)(2.1 + 2.7) ]

= 134.4 m^3.

Answer:

left 29226 Right 134

Step-by-step explanation:

volume=base*height

(22*22+(11)^2 *3.14*3/4)*38=29226

((1.4+0.6)*2*0.7+1.4*2*1.4+0.6*1.4+0.6*1.4))* 16=134

Stefan estimates the income and expenses for renting

Elena-2011 [213]

Answer/Step-by-step explanation:

If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.

Total income estimated in a month:

Sales: $950 per week = 950*4weeks = $3,800 per month

Services: $2,875 per month

Total estimated income per month = $(3,800 + 2,875) = $6,675

Total expenses estimated in a month:

Rent: $4,500 per month

Travel: $7.5 per day = 7.5*7days = $52.5 per week.

Assuming there are 4 weeks in a month, expenses for travel in a month will be:

$52.5*4 = $210

Merchandise: $1,650 per month

Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360

Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

(1 point) Find a formula for the nth term in the sequence: 17,−17/8,17/27,−17/64,17/125,…

lana [24]

Given:

The sequence is:

$17,-\dfrac{17}{8},\dfrac{17}{27},-\dfrac{17}{64},\dfrac{17}{125},...$

To find:

The formula for the nth term in the given sequence.

Solution:

We have,

$17,-\dfrac{17}{8},\dfrac{17}{27},-\dfrac{17}{64},\dfrac{17}{125},...$

The given sequence can be written as

$\dfrac{17}{1^3},-\dfrac{17}{2^3},\dfrac{17}{3^3},-\dfrac{17}{4^3},\dfrac{17}{5^3},...$

The sign are alternative and the absolute value of each term can be defined by the expression $\dfrac{17}{n^3}$ , where n is a natural number.

So, the required formula is:

$a_n=(-1)^{n+1}\dfrac{17}{n^3}$

Therefore, the formula for nth term in the given sequence is $a_n=(-1)^{n+1}\dfrac{17}{n^3}$ .

I’m stuck, need help!!

grigory [225]

Answer:

Step-by-step explanation:

A + B + C = 180

x + x - 24 + 68 = 180

2x - 24 + 68 = 180

2x + 44 = 180

2x = 180 - 44

2x = 136

x = 68

A = 68

B = 44

C = 68
