Answer:

  254.0 cm³

Step-by-step explanation:

The formula for the volume of a sphere in terms of its radius is ...

  V = (4/3)πr³

Then the formula for the volume of a hemisphere in terms of its diameter is ...

  V = (1/2)(4/3)π(d/2)³ = (π/12)d³

The volume of the hemisphere is ...

  V = (π/12)(9.9 cm)³ ≈ 254.024 cm³

The volume is about 254.0 cm³.

Step-by-step explanation:

We only know 1 side, and that is the width of 4. We only have the diagonals at our side. Half of the diagonal is 5. As a result, the diagonal is 10. I want you to imagine a triangle that has a base of 4 and a hypotenuse of 10. Use the Pythagorean Theorem to find b, or the height.

a² + b² = c²

4² + b² = 10²

16 + b² = 100

100 - 16 = 84

b² = 84

b = √84

b ≈ 9.165

Now we know the length of the rectangle, which is about 9.165. Multiply that by 4 to get the area.

9.165 * 4

36 + 0.4 + 0.24 + 0.020

36.4 + 0.24 + 0.02

36.64 + 0.02

36.66 u²

The area of rectangle RSTU is about 36.66 units squared.

Answer: 3

Step-by-step explanation:

From the question, we are informed that Tanisha plans to invite 24 people to a snack and that each package contains 8 invitations.

The number of invitation packages that should be bought will be the number of people to be invited divided by the invitations in each package. This will be:

= 24/8

= 3 invitation packages

Answer:

The correct option is;

B. Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of 52 Towers/(Thousand customers)

Step-by-step explanation:

The given data can be presented as follows;

Cell Phone Towers

Customer (thousands)    [tex]{}[/tex]   Towers

1) 5.25            [tex]{}[/tex]                          273

2) 6.25            [tex]{}[/tex]                         325

3) 7.25            [tex]{}[/tex]                         377

4) 9.25            [tex]{}[/tex]                         481

From the given data, we have the ratio Towers/Customer (thousands) given as follows;

For 1), we have;

273 Towers/(5.25 thousands customers) = 52 Towers/(Thousand customer)

For 2), we have;

325 Towers/(6.25 thousands customers) = 52 Towers/(Thousand customer)

For 3), we have;

377 Towers/(7.25 thousands customers) = 52 Towers/(Thousand customer)

For 4), we have;

481 Towers/(9.25 thousands customers) = 52 Towers/(Thousand customer)

Therefore, the ratios of towers to customers (thousands) all have the same equivalent unit rate of 52 Towers/(thousand customers).

Answer:

Hichman will walk faster.

Step-by-step explanation:

Hichman walks 84 feet in 7 seconds and Brittany walks 110 feet in 20 Second.

We need to say who walks faster.

For Hichman,

Distance, d = 84 feet and time, t = 7 s

Speed,

[tex]v_H=\dfrac{d}{t}\\\\v_H=\dfrac{84}{7}\\\\=12\ ft/s[/tex]

For Brittany,

Distance, d = 110 feet and time, t = 20 s

Speed,

[tex]v_B=\dfrac{d}{t}\\\\v_B=\dfrac{110}{20}\\\\=5.5\ ft/s[/tex]

It can be seen that speed of Hichman is 12 ft/s and the speed of Brittany is 5.5 ft/s. It is clear that the speed of Hichman is more than that of Brittany. Hence, Hichman will walk faster.

Answer:

y = 4x -3

Step-by-step explanation:

Here, we want to get the equation of the blue line

As we can see, the y-intercept is -3

So we have the equation as;

y = mx -3

To get the value of m which is the slope , we check for any point on the line

That would be;

(1,1)

Let us have this substituted;

1 = m(1) - 3

1 = m -3

m = 1 + 3

m = 4

so the equation of the straight line is;

y = 4x -3

Answer:

b

Step-by-step explanation:

Answer:

The time required to get  a total amount of $ 12,600.00  from compound interest on a principal of $9000  at an interest rate of 4.75% per year  and compounded 4 times per year  is 7.1 years.

Step-by-step explanation:

Given

Principle P = 9000 dollars

Rate r = 4.75% = 0.0475

Total Amount A = 12600 dollars

compounded quarterly n = 4

To determine:

Time t = ?

Using the equation

[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]

solving the equation for 't'

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(12,600.00/9,000.00) / ( 4 × [ln(1 + 0.011875/4)] )

t = 7.1 years

Therefore, the time required to get  a total amount of $ 12,600.00  from compound interest on a principal of $9000  at an interest rate of 4.75% per year  and compounded 4 times per year  is 7.1 years.

Answer: 2520

Step-by-step explanation:

Given: Number of people supported the visiting team = 882

Let x = Total number of people at the game.

As per given,

35% of x = 882    [35% were supporting the visiting team]

[tex]\Rightarrow\ 0.35x=882\\\\\Rightarrow\ x=\dfrac{882}{0.35}\\\\\Rightarrow\ x= 2520[/tex]

Hence, the total number of people at the game = 2520 .

Answer:

Volume of B is 360 [tex]cm^{3}[/tex]

Step-by-step explanation:

It can be observed in the question that the dimensions of cylinder B are twice the dimensions of cylinder A, since both are similar.

Height of B = 2 x height of A

                   = 2 x 5

                   = 10 cm

cross sectional area of B = 2 x cross sectional area of A

                            = 2 x 18

                             = 36 [tex]cm^{2}[/tex]

Thus,

Volume of B = cross sectional area x height

                     = 36 x 10

                     = 360 [tex]cm^{3}[/tex]

Volume of B is 360 [tex]cm^{3}[/tex].

Answer:

i. Salesperson's commission = $27.225

ii. Amount for the store = $467.775

Step-by-step explanation:

The commission of the salesperson = [tex]5\frac12\%[/tex] of selling price

Price of a couch = $495

Salesperson's commission = [tex]5\frac12\%[/tex] of $495

                                             = [tex]\frac{11}{200}[/tex] x 495

                                             = 27.225

Salesperson's commission = $27.225

Amount that the store would get from the sale = selling price - commission

                                                 = $495 - $27.225

                                                 = $467.775

The store would get $467.775 from the sale of the couch.

Answer: Slope-Intercept

Answer:

The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]

Step-by-step explanation:

Intercepts of a Function

Given a function y=f(x), the intercepts with the x-axis, if any, can be found by solving the equation:

y = f(x) = 0

The intercepts with the y-axis can be found by calculating

f(0)

We are given the function

y - 4x = 1

To find the x-intercepts, set y=0:

0 - 4x = 1

Solving:

[tex]x = -\frac{1}{4}[/tex]

For x=0:

y - 4*0 = 1

y = 1

The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]
