Just think of it as normal subtraction. They both have the same denominators all you need to do is subtract. 11/12-7/12 is 4/12 if you simplify which just means to find the number that both 4 and 12 can go into equally the simplified answer would be 1/3. You just need to divide 4 by both the top and the bottom (numerator and denominator).

You have a spinner with 4 sections labeled A, B, C & D. You plan to spin the spinner once and then roll a number cube. What is the probability that the spinner will land on B and the dice will land on an even number?

Answers

Answer:

1/4 possibility of choosing B and 1/2 possibility of getting an even number.

Step-by-step explanation:

B has a 1/4 chance of being picked since there are 4 sections. A cube has 3 even numbers . . . and a cube has 3 odd numbers. The total amount of numbers on a cube is 6, since there are 3 even numbers it is 3/6 which is reduced to 1/2.

Volume of a rectangular prism=[tex]\frac{1}{2}[/tex]b x l x h

Set up you equation

120=[tex]\frac{1}{2}[/tex](4 x 12 x [tex]x[/tex])

Multiply inside the parentheses

120=[tex]\frac{1}{2}[/tex](48x)

Multiply by [tex]\frac{1}{2}[/tex]

120=24x

Divide by 24 on both sides

5=x

Check you answer

Volume of a rectangular prism=[tex]\frac{1}{2}[/tex]b x l x h

Set up your equation

Answers

Answer:

1646/1

Step-by-step explanation:

To write 1646 as a fraction you have to write 1646 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

1646 = 1646/1 = 16460/10

technically it should be 1646/1 because it’s a whole number, and whole numbers are always over the number one when you write them as fractions.

Tyshawna and Jean both work at a sneaker store and make a fifthteen dollar commission for every sneaker sold. However, Jean makes a flat rate of 75 dollars a day because he has been working at the store longer than Tyshawna. Tyshawna makes a flat rate of 65 dollars a day.
(a. Will Tyshawn and Jean ever make the same amount of money in a day? Why or why not?

Answers

Answer:

Since Jean makes a higher flat rate than Tyshawna, they won't make the same amount in a day. Jean makes a flat rate of 75 dollars a day, while Tyshawna makes a flat rate of 65 dollars a day. Tyshawna is only a few flat rates behind. Although it would seem like they could make the same amount, they wouldn't be able to. If they both had the same flat rate, they would be making the same amount almost everyday.

I hope I helped :)

Answer:

yes, because the total pay is based on how many shoes are sold and not how long one has been there so if Tyshawna sells more shoes her or his pay rate will rise.

I really do not want answers that do not make sense, thank you.

Answers

Answer:

So 5+-6=-1

Step-by-step explanation:

So we know that n is negative so the x also have to be a negtive but higher then the first number in the equation. So i used -6 because its higher than 5 and will it eqaul to a negtive number which is -1

Answer:

x has to be a negative number less than negative 5. Possible solutions, -6, -7 or -8

Step-by-step explanation:

For N to be a negative number, one of the numbers in the equation has to be a number less than -5. If you add two positives together you get a positive number. So you need to add a positive and a negative. But if you add -5, -4, -3, -2, -1 to 5 you would not get a negative number.

Example:

x=-6

5+-6=-1

x=-7

5+-7=-2
