Let <em>x</em> = 3.191919…. Then 100<em>x</em> = 319.191919…, and we have

100<em>x</em> - <em>x</em> = 319.191919… - 3.191919…

99<em>x</em> = 316

<em>x</em> = 316/99

Next, we have

316 = 297 + 19 = 3 × 99 + 19

so

316/99 = (3 × 99 + 19)/99 = 3 + 19/99

Ne4ueva [31]

Answer:

13

Step-by-step explanation:

Explanation:

Use the absolute value definition to rewrite the absolute value equation as two separate equations.

k-10=3

k-10=-3

Solve the equation for k

k=13

k-10=-3

k=13

k=7

The equation has 2 solutions, meaning k1=7,k2=13. Which gives you the answer of: 13 (K1=7,k2=13)

A box contains four equal sized cards labeled 1, 3,5, and 7. Tim will select one card from the bow. What is the probability that
Zielflug [23.3K]

Answer: The probability is zero.

Step-by-step explanation:

The labels on the 4 cards are 1, 3, 5 and 7. Because the cards are equal, the probability of dragging at random each one of them is equal to 1/4 = 0.25.

Now, the probability that Tim selects a card labeled with a 4 is equal to the number of cards labeled with a 4, divided the total number of cards.

We do not have cards labeled with a 4, so the probability is:

p = 0/4 = 0

because we do not have any card labeled with a 4, the probability of selecting one at random is equal to zero.

Sam and his friend went out for pancakes. They ordered a huge stack of pancakes but the waitress didn't give them enough maple syrup. Sam got 1/5 of a cup of syrup and his friend got 1/2 of a cup. If they wanted a lot of syrup, they would have to combine their cup of syrup.
How much syrup would they have if they combined their cups of syrup?

Now solve.
First, find the common denominator
10 is the common denominator
1/5=2/10 1/2=5/10
2/10+5/10=7/10

Sam and his friend has 7/10 cups of syrup, now they have enough and are satisfied
