What is the product of 5 and 1/3? Write your answer in simplest form.
1. 15
2. 1/15
3. 15/3
4. 1 2/3

Answers

Answer: 1 2/3

Step-by-step explanation:

To find the product of fractions, you multiply the denominator and the numerator. 5 isn't a fraction so you can make it a fraction by keeping 1 as the denominator. So 5 as a fraction is 5/1. 5/1 times 1/3 = 5/3. 5/3 as a mixed number is 1 2/3.

Product means to multiply. So, 5 x 1/3 = 5/3 or in decimal form: 1.67

what is the gfc of h^4 and h^8​

Answers

Answer:

23

Step-by-step explanation:

Answer: h^4

We can write h^8 as h^(4+4) = h^4*h^4. So buried inside h^8 are two copies of h^4 multiplied together

So both terms have a greatest common factor of h^4

If you had something like h^4 + h^8, then it would factor to h^4(1 + h^4)

A system of equation is shown.

y=x+6

Enter a numeric value to complete the solution of the system.

Answers

Answer:

y = 245 / 7, x = 29

Step-by-step explanation:

make both into ax + by = c format which is

Math:

5x + 2y = 245

-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.

[(Side Note) if both were positive then you would need to do

EX: - 5 (- x + y = 6)]

Continued:

7y = 275 ==> 7y/7 = 245/7

y = 245 / 7

Plug it in the most convenient one which has the equation y = x + 6

and tweak it a bit

x = y - 6

x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7

x = 203 / 7 ==> 29

I think he is right but the answer is 5x+2y=245.
Y=x+6

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
please help me i will give brainliest to first person to anwser.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Although this is not necessarily a verifiable number, it does show the magnitude of the consolidations that have taken place in the passenger airline industry. Probably the most significant combinations of carriers began in 2009 with Delta and Northwest, followed by United and Continental in 2010, Southwest and Airtran in 2011, and American and US Airways in 2013. These four "mega-carriers" account for approximately 80 percent of all domestic airline passengers today. The Airline Deregulation Act of 1978 was intended to open the passenger market to new entrants to increase the level of competition. Since then, however, there have been no new entrants into the traditional hub-and-spoke airline market. While there have been a few successful entrants into the market (for example, Southwest), they were point-to-point airlines that did not compete against the legacy hub-and-spoke carriers (for example, United).In your opinion, why did the Justice Department allow such consolidations to take place?
