What is 6476 divided by 12
Inessa [10]

The easiest way to solve this, is expressing the division as a fraction, and then use divisibility rules to simplify our fraction.

Remember that saying 6476 divided by 12 is the same as \frac{6476}{12}. Just like that we have our fraction. Now to simplify it, we are going to use divisibility rules

Remember that to simplify a fraction using divisibility rules, both numerator and numerator must by divisible by the same number.

- Divisibility by 2

A number is divisible by 2 if and only if it ends in 0, 2, 4, 6, or 8. In other words, a number is divisible by 2 if its last digit is even or zero.

Notice that 6476 ends in 6, so it's divisible by 2, and 12 ends in 2, so it's also divisible by 2. Since both the numerator and denominator of our fraction are divisible by 2, we can simplify our fraction dividing both numerator and denominator by 2. To divide by 2, we just need to find the half of each number. The half of 6476 is 3238 and the half of 12 is 6, so we can simplify our fraction as follows:

\frac{6476}{12} =\frac{3238}{6}

3238 ends in 8, so it's divisible by 2; 6 ends in 6, so it's divisible by 2. The half of 3238 is 1619 and the half of 6 is 3, so we can simplify our fraction even more:

\frac{3238}{6}=\frac{1619}{3}

Now, 1619 does end in zero or an even number, so it's not divisible by 2; similarly, 3 is not even even, so it's not divisible by 2. Let's check if they are divisible by 3

- Divisibility by 3

A number is divisible by 3 if an only if the sum of its digits is 3 or multiple or 3.

Let's check if the numerator of our fraction, 1619, is divisible by 3:

1+6+1+9=17 Since 17 is not a multiple of 3, 1619 is not divisible by 3.

Now, let's check if our numerator, 3, is divisible by 3:

3 is a multiple of 3, so its divisible by 3.

Since our numerator is divisible by 3 but our denominator is not, we can't further simplify our fraction.

We can conclude that the result of 6476 divided by 12 is \frac{1619}{3}, or expressed as decimal: 539.666666667.

Joanne works two jobs to pay for college. She tutors for $25 per hour and also works as a receptionist for $12 per hour. Due to
il63 [147K]

Answer: C. t+r\leq 25

25t+12r\geq 200


Step-by-step explanation:

If 't' represents the number of hours Joanne tutors and 'r' represents the number of hours she works as a receptionist.

Then the total hours she can work=t+r

Since she can work up to 25 hours.

Thus t+r\leq 25

If she earns $25 per hour by tuition and $ 12 per hour by working as a receptionist .

Then her total earning =$25t+12r

Since she must earn $200.

Then 25t+12r\geq 200.

Therefore, the required system of inequality will be

t+r\leq 25

25t+12r\geq 200

Need help with this plz
madreJ [45]

Answer:

4. x = 16.8

5. x = 35.98

Step-by-step explanation:

For both triangles that you need to work on, use the trigonometric function which is tan and you are dividing opposite by adjacent for the answers.

For number 4, the equation you are setting up is tan 35 = x/24.  Multiply 24 on both sides to get the answer which is 16.8 for the x side.

For number 5, the equation you are setting up is tan 17 = 11/x.  As a result on your calculator, you should get 35.98 for the x side.
