Answer:

If 40 percent off 15copies and each copies 100 pounds then it would cost 60 pound per copy times it by 15 = 900 pounds

whereas 50 percent off 25 copies = 50 pounds times 25=1250 so therefore you want 40 percent off 15 copies

Find the volume of the sphere. Either enter an exact answer in terms of π πpi or use 3.14 3.143, point, 14 for π πpi and round your final answer to the nearest hundredth.
radius is 8

Answers

Answer:

Solution :-

Volume of sphere = 4/3 πr³

Volume = 4/3 × 3.14 × 8³

Volume = 4/3 × 3.14 × 512

Volume = 4/3 × 1607.68

Volume = 2143 in³

[tex] \\ [/tex]

Given:-

Radius of the sphere is 8 units.

To Find:-

The volume of the sphere.

Solution:-

We know, volume of sphere is [tex] \frac{4}{3} [/tex]πr³

So, volume of sphere = [tex] \frac{4}{3} [/tex] × 3.14 × 8 × 8 × 8

= [tex] \frac{6430.72}{3} [/tex]

= 2143.6

The volume of the sphere is 2143.6 cubic units. [Answer]

Nate is exponentially gaining Twitter followers! His current amount of followers is 146. His followers are increasing at a 24% rate each day. Part 1: Is this a growth or decay problem? ( 1 point) Part 2: Which equation correctly represents this problem (2 points) A) y=146(24)x B) y=146(1.024)x C) y= 146(1.24)x

Answers

Answer:

(a) Growth

[tex](b)\ y = 146(1.24)^x[/tex]

Step-by-step explanation:

Given

[tex]a= 146[/tex] -- current

[tex]r = 24\%[/tex] --- rate

Solving (a): Growth or decay

The question says his followers increases each day by 24%.

Increment means growth.

Hence, it is a growth problem

Solving (b): Equation to represent the scenario.

Since the rate represents growth, the equation is:

[tex]y = a(1 + r)^x[/tex]

Substitute: [tex]a= 146[/tex] and [tex]r = 24\%[/tex]

[tex]y = 146 * (1 + 24\%)^x[/tex]

[tex]y = 146 * (1 + 0.24)^x[/tex]

[tex]y = 146 * (1.24)^x[/tex]

[tex]y = 146(1.24)^x[/tex]

Distance: Jack and Jill start from the same point and walk in'opposite directions. Jack

walks 2 kmh faster than Jill. After 3 hours they are 30 kilometers apart. How fast did

each walk?

Answers

Answer:

t = 6 km/hour

And, J would be 4 km per hour

Step-by-step explanation:

Let us assume the speed of Tom be T

And, the Speed of Jim  be J

Given that  

T - J = 2 km /hr ...........(i)

After 3 hours distance between them  = 30 km

As they are walking in the opposite direction

Thus,  

Net speed =T + J

L ÷ (T+J) = 3

30 ÷ (T+J) = 3

T +J =10 ..............(2)

After solving these two equations

2T = 12

t = 6 km/hour

And, J would be 4 km per hour

I think it's -18 13/24 ?

Answer:

-18 13/24

Step-by-step explanation:

Looking at the two numbers, we need to find a common denominator. To do that, list the multiplies of both numbers & find the first one that is in common.

8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120

6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120

The first multiple 8 & 6 share is 24, so we'll use that as our denominator

-67/8 - 61/6

-201/24 - 244/24

(-201 - 244)/24

Subtract 244 from -201 to get -445.

-445/24

Convert -445/24 into a mixed number.

-18 13/24 is the answer to -8 3/8 - 10 1/6.
