Find the missing numerator or denominator

Dmitrij [34]

Answer:

Finding 1st Fraction Numerators

Explanation:

If you divide the denominator (40) by the first denominator (5), you get 8, so you know that the number 40 can be divided by 8 to get the other denominator (5). Therefore, you must be fair, and divide the numerator (8) by 8 also, which is 1. 1 is the missing numerator.

Regina has a bag of marbles that contains 3 blue marbles, 4 red marbles, and 5 yellow marbles. She draws one marble, then replac

iVinArrow [24]

Answer:

Possible outcomes=12

$P(\text{Blue marble first})=\frac{1}{4}$

$P(\text{Yellow marble})=\frac{5}{12}$

$P(\text{ Blue then yellow})=\frac{5}{48}$

Step-by-step explanation:

We can see these two events are independent as Regina replaced marble after drawing one marble.

We can find possible outcomes by adding number of blue, red and yellow marbles.

$\text{Possible outcomes}=3+4+5=12$

Let us find probability of getting a blue marble on first draw.

$P(\text{Blue marble})=\frac{3}{(3+4+5)} =\frac{3}{12} =\frac{1}{4}$

Now we will find probability of getting yellow marble.

$P(\text{Yellow marble})=\frac{5}{(3+4+5)} =\frac{5}{12}$

We can find probability of getting a blue marble and then yellow marble by multiplying both probabilities.

$P(\text{ Blue then yellow})=\frac{1}{4}* \frac{5}{12} =\frac{5}{48}$

Therefore, probability of getting a blue marble and then yellow marble is $\frac{5}{48}$ .

0.3(4-x)=x-1.4 how do you solve this problem?

tresset_1 [31]

Answer:

x = 2.

Step-by-step explanation:

Solve for x:

0.3 (4 - x) = x - 1.4

Expand out terms of the left hand side:

1.2 - 0.3 x = x - 1.4

Subtract x from both sides:

1.2 + (-0.3 x - x) = (x - x) - 1.4

-0.3 x - x = -1.3 x:

-1.3 x + 1.2 = (x - x) - 1.4

x - x = 0:

1.2 - 1.3 x = -1.4

Subtract 1.2` from both sides:

(1.2 - 1.2) - 1.3 x = -1.2 - 1.4

1.2 - 1.2 = 0:

-1.3 x = -1.2 - 1.4

-1.2 - 1.4 = -2.6:

-1.3 x = -2.6

Divide both sides of -1.3 x = -2.6 by -1.3:

(-1.3 x)/(-1.3) = (-2.6)/(-1.3)

(-1.3)/(-1.3) = 1:

x = (-2.6)/(-1.3)

(-2.6)/(-1.3) = 2.:

Answer: x = 2.

How is 0.09 smaller than 0.1

denis-greek [22]

Answer:

$0.09 < 0.1$

Step-by-step explanation:

Remember that it doesn't matter how many numbers are after the tenths place of a decimal point what matters is the tenths place itself. If you have a decimal that has dozens of numbers but it's tenth place is a 3 and then you have a decimal with 5 numbers in whole but it's tenths place is 4, the 4 is greater then the 3 simply because it's greater in tenths.

Hope this helps.
