Round 6 6/13 to the nearest whole number.

Answers

6.

1/3 is not 1/2 or more than 1/2 so you have to round down.

Rounding to the nearest whole number involves writhing out the value of a number to the nearest integer value. Hence, the number would be written as 6

Converting the fractional value to decimal ; 6 61/3 = 6.461

Since the first digit after the decimal point is less than 5, we round to 0

Therefore, the number would be written as 6 (nearest whole number).

Answer:

There will be an estimated amount of 1125 faulty souvenir tokens.

Step-by-step explanation:

Hi!

So, let's do this problem out.

So we for every 400 tokens, 3 are faulty

Let's write that in a ratio

3:400

Ok, great!

So, now we know that:

3:400 = x:150,000

We can set up a percent proportion

[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]

To find x, we do:

[tex]x=\frac{3*150,000}{400}[/tex]

[tex]x=\frac{450,000}{400}[/tex]

[tex]x=\frac{4,500}{4}[/tex]

[tex]x=1125[/tex]

There will be an estimated amount of 1125 faulty souvenir tokens.

Give an example of an equation with an infinite number of solutions. Then make one change to the equation so that it has no solution.

An example of an equation with infinitely many solutions: 4x + 3 = 4x +_____
The equation with one change and no solutions: 4x + 3 = ______

Answers

Answer:

I)3   II)4x

Step-by-step explanation:

for the infinite number of solutions you need to make both equations on both sides equal

but in the one for no solution you need to make one number is equal to another number, which is wrong in Math, that's why there's no solution in it

Our bases in this problem are 60.5 and 75.5. We are going to addd these together and we’re going to get, 136.
Now, we must multiply 136, by its height(16). 136 x 16 = 2176.
Lastly we are going to divide by 2 and get our final answer of 1088 feet cubed.

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.

a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.

Answers

Answer:

Equation: y=(-1/20)x+12.

Slope: -1/20

Y-intercept: (0, 12)

Step-by-step explanation:

Let x=the number of gallons of gas in Christopher's car.

If we start with 12 gallons, we have the equation: y=(-1/20)x+12.

This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

What is Arithmetic Mean?

The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.

Given:

According to box plot the mean is

= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26

= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26

= 195 / 26

= 7.5

Hence, the mean is 7.5.

Also, the median = (7+8)/2 = 7.5
