Answer:

question 1 part a =

estimated number of dogs

=6.99 × 107

= 6.99 • 10,000,000

= 69,900,000

estimated number of cats

= 3.61 × 107

= 3.61 • 10,000,000

=36,100,000

estimated number of birds

= 8.3 × 106

= 8.3 • 1,000,000

= 8,300,000

part b = total population of pet dogs, cats, and birds  

= 69,900,000 + 36,100,000 + 8,300,000

= 114,300,000

question 2 part a =

The estimated number of dogs is 6.99 x 10^7 .

The estimated number of cats is 3.61 x 10^7.

The estimated number of birds is 8.3 x 10^6.

The power of  10 in  8.3 x 10^6  is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same.

Multiply and divide 8.3 x 10^6 by 10 to increase its exponent by 1:

8.3 x 10^6 = 10/10 x 8.3 x 10^6

                 = 8.3/10 x 10^6 x 10

                 = 0.83 x 10^7

part b =

total number of pet dogs, cats, and birds

=

6.99 × 107 + 3.61 × 107 + 0.87 × 107

=

(6.99 + 3.61 + 0.83) • 107

=

11.43 • 107

part c =

No. The sum from part B is not in scientific notation.

The total number of pet dogs, cats, and birds is 11,43 x 10^7. To express the number in scientific notation, the decimal point must be moved one digit to the left. To do that, divide and multiply the number by 10:

10/10 x 11.43 x 10^7 = 11.43/10 x 10^7 x 10

                                = 1.143 x 10^8

Written in scientific notation, the total number of pet dogs, cats, and birds is 1.143 x 10^8.

question c = They are the same. If you convert the number in standard form from question 1 to scientific notation, it is the same as the number in scientific notation found in question 2.

The Scientific Notation

Dogs: 6.99 x \(10^8\)

Cats: 3.61 x \(10^8\)

Birds:0.083  x \(10^8\)

Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Also, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.

Given:

We have to change the number in  Scientific Notation in which only one significant number will be before the decimal and remaindering raise to power of 10.

First, Dogs: 69,900,000 whose Scientific Notation is

= 6.99 x \(10^8\)

Second, Cats: 36,100,000 whose Scientific Notation is

= 3.61 x \(10^8\)

Third, Birds: 8,300,000 whose Scientific Notation is

= 8.3 x \(10^6\)

= 0.083  x \(10^8\)

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:

|x-3x^5|=6+y

y<0

|9-y+6|=21

|15-y|=21

15-y±21

either 15-y=21

-y=6

y=-6

or 15-y=-21

y=36

but y<0

so y=-6

|x-3x^5|=6+y

|x-3x^5|=6-6

|x-3x^5|=0

x-3x^5=0

x(1-3x^4)=0

either x=0

or 1-3x^4=0

or (1-√3 x²)(1+√3x²)=0

1-√3 x²=0

x²=1/√3

x=±√(1/√3)

x²=-1/√3

x=±(1/√3)i

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Answer:

1/64 cubic yards or 0.015625 cubic yards

Step-by-step explanation:

A cube has equal edge lengths.

To find the volume of a cube using edge length, simplify raise the value of the edge length to the 3rd power or cube it.

⇒ V = (edge length)³

Using this formula and keeping in mind the edge length is 1/4 yd, substitute it in the formula.

Answer:

Step-by-step explanation:

Given that, Length of each edge of the cube is 1/4 yard.

Using formula:

\( \: \: \dashrightarrow \: \: { \underline{ \boxed{ \pmb { \sf{ \purple{Volume _{(cube)} = (edge) ^{3} }}}}}} \\ \)

On substituting the value of edge in the above formula, we will get the required volume of the cube.

\( \: \: \dashrightarrow \: \: \rm Volume = \bigg( \dfrac{1}{4} \bigg) ^{3} \\ \)

\(\: \: \dashrightarrow \: \: \rm Volume = \dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4} \\ \)

\(\: \: \dashrightarrow \: \: { \underline{\boxed{ \purple{\pmb{ \sf {Volume = \dfrac{1}{64} \: {yd}^{3} }}}}}} \\ \\ \)

Answer:

5/8 + 9/7 +107/56

Step-by-step explanation:

5/8+9/7=5x7/8x7+ 9x8/7x8=35/56 + 72/56= 35+52/56=107/56

The simplified version of this would be 1 51/56

PLEASE MARK AS BRAINLIEST!!!!!

The sum of the two given fractions is 107/56.

The given fractions are 5/8 and 1 2/7.

We need to find the sum of given fractions.

When the denominators are different, the fractions are called, unlike fractions. In such fractions, the first step is to convert them to like fractions so that the denominators become common. This is done by finding the least common multiple (LCM) of the denominators.

Now, we can write 1 2/7 as 9/7.

So, 5/8 + 9/7

Here, LCM of 8 and 7 is 56

Then, 35/56 + 72/56

=(35+72)/56

=107/56

Therefore, the sum of the two given fractions is 107/56.
