Answer:

D. 735.25 cubic inches.

Step-by-step explanation:

Well hello there! My name is Lunako, and I'm here to help you out.

Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.

4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18  + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}

4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}

4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}

12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}

735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}

735.25 in³ {And with that this problem is solved.}

The volume of the sphere is 735.25 cubic inches, which is D.

She buys coffee three times a week for $5.

She spends 3 *$5 per week on coffee

She spends $15 per week on coffee

Answer:

$45.05

Step-by-step explanation:

Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50.  Nya has to pay 6% sales tax on this $42.50.  Thus, the final amount due is

(1.00 + 0.06)($2.50) = $45.05

Answer:

46.42

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

= 55 * 20%

= 55*.20

=11

Take the discount from the original price and that is the new price

new price = original price - discount

= 55-11

=44

Now we need to find the tax

tax = new price * tax rate

= 44 * 5.5%

= 44 * .055

=2.42

The final price is the new price plus the tax

final price = new price + tax

= 44+2.42

=46.42

Therefore, Nya will pay $46.42 for the sweater if she buys it.

Step-by-step explanation:

Answer:

x = 1.63 units

Step-by-step explanation:

For 30 degree angle,

Hypotenuse = x

Base = [tex]\sqrt2[/tex]

We know that,

[tex]\cos\theta=\dfrac{B}{H}[/tex]

B is base and H is the hypotenuse

So,

[tex]\cos(30)=\dfrac{\sqrt2}{x}\\\\x=\dfrac{\sqrt2}{\cos(30)}\\\\x=1.63[/tex]

So, the value of x is equal to 1.63 units.

Answer:

-50

Step-by-step explanation:

I got it correct on iReady Practice: Multiply and Divide Rational - Practice - Level G.

-5 1/12 x 10

The required change in the position of the drill in one day is given as 50 feet. Option B is correct.

Given that,
A research team is planning to use an ice drill at the top of a glacier. The team plans to use the drill for 10 hours each day while the temperature is warmest. The drill's position will move 5 1/12 feet every hour it is used.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Drill length  = 5 1 / 12 = 61 / 12 feet per hour
For 10 hours in a day drill length = 61 / 12 [10] = 50.833 or 50 feet.

Thus, the required change in the position of the drill in one day is given as 50 feet. Option B is correct.
