Add and Simplify 9/12+1/2

Mathematics

Step One: Since when you add and subtract fractions they need to have the same denominator. So you find the least common denominator. Which is 6.

Step Two:So, now you have your least common denominator. Now you multiply 1/2 * 6. Remember whatever you do to the bottom you do to the top. So you multiply 2 and 6, then multiply 1 and 6. Which will leave you with 6/12.

Step Three:Now you add the numerator. Remember you the denominator ALWAYS STAYS THE SAME. The Denominator always stays the same when you add and subtract fractions. So, 9/12 + 6/12 = 15/12. 

Step Four:Now you simplify. So you divide 15 / 12=  1 with the remainder of 3. Like I said before the denominator ALWAYS STAYS THE SAME. So you now have 1 3/12. We can still simplify that number.  So we divide by the least common denominator which is 3. Remember whatever you do to the bottom you have to do to the top. The whole number stays the same as well. So divide    1 3/12 / 3 = 1 1/4. So, the answer is 1 1/4

A ball is kicked off of the roof of a building. The path the ball travels is modeled by the equation f(x)= -x^2 + 6x+ 16, where
damaskus [11]

Answer:

This question is a rather easy one which can be answered by simply solving the embedded quadratic equation.

f(x) = -x^{2} + 6x + 16

To make our solving easier, what we do is multiply the whole equation by -1. By so doing, we make "x" positive. Then, we have

f(x) = x^{2} - 6x - 16

Solving this equation quadratically, we have

x^{2} + 2x - 8x - 16 = and when we factorize this expression, we have

x(x + 2) -8(x + 2) =

(x - 8) (x + 2) = 0

x - 8 = 0, x + 2 = 0

x = 8, or  x = -2

Since distance can not be in negative(minus), we then have our x to be 8 meters.

A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape....
frosja888 [35]

Answer:

About 41.5%

Step-by-step explanation:

<em>Given:</em>

<em>A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape.</em>

<em>To Find:</em>

<em>What is the probability that both grapes are red?</em>

<em>Answer choices:</em>

<em>about 39.7%</em>

<em>about 41.5%</em>

<em>about 42.5%</em>

<em>about 44.5%</em>

<em>Solution:</em>

<em>Since, there are 8 green grapes and 15 red grapes, the total number of grapes is 23 .</em>

<em>As the red grapes are 15..</em>

<em>Thus,</em>

<em>The probability of choosing a red grape the first time is 15/23.</em>

<em>Because out of the total 23 grapes only 15 were red grape.</em>

<em>The probability of choosing the red grape the second time will be 14/22. Because the number of red grapes has already decreased by one and so is the total number of grapes after first choice</em>

<em>Hence, the probability of choosing or eating two red grapes will be :</em>

<em>15/23×14/22</em>

<em>=105/253</em>

<em>=0.415</em>

<em>= 41.5%</em>

<em>Therefore, the probability that both grapes are red is about 41.5%</em>

This question is really confusing me, it talks about unknown angle problems with Algebra.
Sever21 [200]

Answer:

20

Step-by-step explanation:

The two given and marked angles add up to 90.

A = x

B = 3x + 10

A + B = 90          Substitute for A and B. A and B are just letters I gave things.

x + 3x + 10 = 90        Combine the left

4x + 10 = 90              Subtract 10 from both sides.

4x +10-10 = 90-10     Combine

4x = 80                      Divide by 4

4x/4=80/4

x = 20
