A bag contains 3 red marbles, 7 blue marbles and 4 green marbles. If three marbles
are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that
all three marbles drawn will be blue?

Answer:

1 = -x

Step-by-step explanation:

group like terms together so

this 5 + 4x - 7 = 4x -3 - x

becomes this 5 - 7 + 3 = 4x -4x -x

then simplify     1 = - x  

Answer:

C

Step-by-step explanation:

Answer:

c.

Step-by-step explanation:

Starting with the multiplications, first the multiply matrix A by -4, so we multiply every value in the matrix by -4 and we get

16 16 -4

-4 -16 -28

-8 -12 -12

Then we do the next multiplication which is 8 by matrix B, so once again we multiply every value in the B matrix by 8

16 72 -72

64 64 -16

32 80 8

Now that we did both multiplications, just need to sum the results, so we sum each value of matrix A with the value on the matrix B that's on the same spot

16 + 16 16 + 72 -4 + (-72)

-4 + 64 -16 + 64 -28 + (-16)

-8 + 32 -12 + 80 -12 + 8

And the final result is

32 88 -76

60 48 -44

24 68 -4

So it's option c

Answer:

0.737 rounded to nearest hundredth =

0.74

0.737 rounded to nearest tenth =

0.7

The number before any decimal place below 5 will stay the same.

Answer:

Nearest hundreth 0.74

Nearest tenth 0.7

Step-by-step explanation:

If the number to the right of the place value is larger, then that number will go up by 1. If the number is lower, then the place value will stay the same, and the entier number will be shortened.

So 0.737 to the nearest hundreth becomes 0.74

And 0.737 to the nearest tenth becomes 0.7

Answer:

186%

Step-by-step explanation:

Looking at the squares, we can see that the first one has been completely shaded. That means that it is 100% shaded.

The second square has 86 out of 100 squares shaded, so that means that it is 86% filled.

Therefore 186% is filled by the shaded area.

Answer: -3 2/5

Step-by-step explanation:

When both integers are negative, you can treat them the same as positive numbers and add a negative sign to your final sum.

1+2 2/5 (or 2 4/10 or 2.4) is equal to 3 2/5. So (-1)+ (-2 2/5) is equal to -3 2/5, or -3.4.

Answer:

0.9375 is rational

Explanation:

A rational number is any integer, fraction, or terminating decimal (which 0.9375 is)

The decimal number 0.9375 is a rational number.

Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

A rational number is any integer, fraction, or terminating decimal (which 0.9375 is). The given number 0.9375 is a rational number because it can be written in the form of the fractions like p / q.

Therefore, the decimal number 0.9375 is a rational number.

Answer:

96 inches

Step-by-step explanation:

Because we already have the perimeter, we have to solve the formula for L (length). To do this, simply subtract 2W (width) from both sides so that we're left with 2L by itself. The formula is now 2L= P-2W. When we plug in the numbers we get 2L= 20'-2(2'). All we have to do is solve for L.

2L= 20'-4'

2L=16'

[tex]\frac{2L}{2}[/tex]=[tex]\frac{16}{2}[/tex]

L=8'

We need the answer to be in inches, so multiply 8(12) to get 96''

Answer:

This ratio would be 12:1

Step-by-step explanation:

There's 12 gallons of water to 1 cup of cleaner.

Answer:

you would need 12 gallons of water.

Step-by-step explanation:

The ratio is 4 : 1/3. This means that for every 1/3 cups of cleaner, there is 4 gallons of water.

This in mind, 3 1/3 cups of cleaner would be 1/3 x 3.

Whatever you do to one side, you have to do to the other.

4 gallons x 3 = 12.
