Humans shed about three million particles of skin every five hours. Humans can shed about fifty thousand particles of skin every five minutes. The approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is __

Answers

Answer: The approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is 6 .

Step-by-step explanation:

Given: Humans shed about 3million particles of skin every 5 hours.

Since, 1 million = 1,000,000

Then 3 million = 3 x 1 million

[tex]= 3 \times1,000,000[/tex]

[tex]= 3,000,000[/tex]

[tex]=3\times10^6[/tex]

On comparing to [tex]a\times 10^{b}[/tex] , we get a = 3 and b=6

So, the approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is 6 .

Answer:

6

Step-by-step explanation:

First, write the approximate number of particles of skin a human can shed in five hours in scientific notation. This number is three million which can be written in the form a × 10b, where a is 3 and b is 6.

The graph below models the late fee for overdue books at the library what is the unit rate for the cost of an overdue book at this library?
A)$2 per day
B)$4.50 per day
C)$0.50 per day
D)$1 per day

Answers

Answer:

The answer is C. $0.50 per day .

Hope this helps

Option C is correct, $0.50 per day is the unit rate for the cost of an overdue book at this library.

The unit rate is the cost per one unit of a given quantity.

In this case, it's the cost of an overdue book per day.

In the given graph models the late fee for overdue books, you can find the unit rate by identifying two points on the graph and calculating the slope between those points.

Suppose you have two points on the graph: (x₁, y₁) and (x₂, y₂), where x represents the number of days the book is overdue, and y represents the corresponding late fee in dollars.

The formula for calculating the slope (m) between two points is:

m = (y₂ - y₁) / (x₂ - x₁)

Let us take two points from graph: (4, 2) and (6, 3)

Unit rate = 3-2/6-4

=1/2

=0.5

Hence, $0.50 is the unit rate for the cost of an overdue book at this library. Option C is correct.

Find the values of x and y. 3x - 5 5y - 4 y + 12​

Answers

The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.

What is an equilateral triangle?

An equilateral triangle is a triangle that has all its sides equal to each other.

Therefore,

3x - 5 = 5y - 4 (equilateral triangle)

3x - 5y = 1

Therefore,

y + 12 = 3x - 5 (Isosceles triangle)

y - 3x = - 17

Hence,

3x - 5y = 1

- 3x + y = - 17

-4y = -16

y = -16 / -4

y = 4

Therefore,

3x = 1 + 5(4)

3x = 21

x = 21 / 3

x = 7

The length and breadth of a rectangle are in a 15 : 11 ratio. If the length is 56 cm more than the breadth, find the perimeter of the rectangle.​

Answers

Answer:

g

Step-by-step explanation:

Answer:

Perimeter of rectangle = 728 cm

Step-by-step explanation:

Length :  breadth = 15 : 11

Length = 15x

Breadth = 11x

15x - 11x = 56 cm

         4x = 56

           x = 56/4

           x = 14

Length = 15 *14 = 210 cm

Breadth = 11 * 14 = 154 cm

Perimeter of rectangle = 2 * ( length + breadth)

                                     = 2 *(210 + 154)

                                     = 2 * 364

                                      = 728 cm

Jon caught four fish that weighed a total of 264 pounds. The kingfish weighed twice as much as the
amberjack and the white marlin weighed twice as much as the kingfish. The weight of the tarpon was 5
times the weight of the amberjack.
How much did each fish weigh?

Answers

Answer:

Amber jack 22 pounds

Tarpon 110 pounds

King fish = 44 pounds

White Marlin = 88 pounds

Step-by-step explanation:

Let the weight of the amber jack be x pounds

Kingfish weighed twice as much = 2 * x = 2x pounds

White Marlin weighed 2 times kingfish

= 2x * 2 = 4x pounds

Tarpon weighs 5 times amber jack = 5 * x = 5x

Add all together to give 264

5x + 4x + 2x + x = 264

12x = 264

x = 264/12

x = 22 pounds

Hence ;

Amberjack weighs 22 pounds

Tarpon = 5 * 22 = 110 pounds

Kingfish = 2 * 22 = 44 pounds

White Marlin = 2 times king fish = 2 * 44 = 88 pounds

Simon went to high school from 2012 to 2017. He was born when his father was 25. Simon’s parents met while they were in high school together. Part A Choose the compound inequality that describes the year x when Simon’s parents met.

Answers

Answer:

Simon started High school in the year 2012.

One usually starts highs school when is 14 years old.

So we can assume that Simon was born 14 years before 2012:

2012 - 14 = 1998

Now, Simon's parents may have met in the beginning of 1998, and Simon was born by the end of 1998. But in that case, Simon would be 13 at the beginning of school, instead of 14.

Then Simon's parents should have met before 1998.

Then the inequality that we have:

x < 1998.

And Simon was born when his father was 25 years old.

Then in 1998, Simon's father was 25 years old.

Meaning that he was born around:

1998 - 25 = 1973.

This means that Simon's parents met in-between the years 1973 and 1998.

1973 < x < 1998

Animal riddle
In reply to an inquiry about the animals on his farm, the farmer says: “I only ever keep sheep, goats, and horses. In fact, at the moment they are all sheep bar three, all goats bar four, and all horses bar five.” How many does he have of each animal?

Answers


Here’s the answer & how to find it! So let us suppose,

X : the no. of sheep he owns

Y : the no. of goats he owns

Z : the no. of horses he owns

This means,

X + Y + Z = Total no. of animals he owns

He says that “They are all sheep bar three.” Which means, the no. of animals other than sheep is 3, i.e.

Y + Z = 3

Similarly,

X + Z = 4 and X + Y = 5

On adding all the three equations, we get

2 ( X + Y + Z ) = 12

This implies,

X + Y + Z = 6

This means that the farmers has a total of 6 animals. And on further solving the equations we find that the he has 3 sheep, 2 goats and a horse.
