Find the value of ab when a=4/7 and b= 4/11

Mathematics

Answer:

16/77

Step-by-step explanation:

<em>When two numbers are close togtether, you want to multiply them.  Since it is ab, you multiply a and b.  </em>

<u>a= 4/7</u>

<u>b= 4/11 </u>

<u>so, 4/7 times 4/11</u>

<em>When you multiply fractions, you multiply the numerators (the top number of a fraction) of the fractions together.  You also multiply the denominators(the bottom number) of the fractions together.</em>

So, let's multiply the numerators first.

<u>4 times 4 equals 16, so that is the new numerator</u>

<u>7 times 11 is 77, so that is the new denominator</u>

Let's combine it into a fraction.  Numerator/denominator= 16/77

<em>Sometimes, you will need to reduce.  Reducing meaning that you divide the fraction by a number so it can't be reduced/divided anymore.  Until a fraction is at it's simplest form.  </em>

<u>Example</u>: 2/4 reduces to 1/2 because both the numerator, 2, and the denominator, 4, can be reduced by 2.  As you can see, 1/2 is at it's simplest form and cannot be reduced any further.

Answer: 16/77

Step-by-step explanation: Here we're asked to evaluate ab

given that <em>a = 4/7</em> and <em>b = 4/11</em>.

So we start by plugging in our given

values for <em>a</em> and <em>b</em> into the problem.

If we do this, ab would then be (4/7)(4/11).

When multiplying two fractions together, we multiply across

the numerator and we also multiply across the denominators.

So (4/7)(4/11) is 16/77 which is our final answer.

(x-3) (x-4) polynomial
Debora [2.8K]

Answer:

x^{2} -7x +12

Step-by-step explanation:

Using the Foil method

you multiply x times x and get x^{2}

Then you multiply -4 times X and get -4x

Then you multiply -3 times X and get -3x

then you add -4 and -3 together and get -7x

Lastly you multiply -4 and -3 and get 12

And there you have it

x^{2} -7x +12

If a car travels 792 feet in 12 seconds what is the speed of the car in miles per hour?
UkoKoshka [18]

Answer:

Step-by-step explanation:

1 mile contains 5280 feet

x mile contains 792 feet             Cross Multiply

5280 x = 792                               Divide by 5280

x = 792 / 5280

x = 0.15 miles

1 hour = 3600 seconds

Distance travelled in 12 sec = 0.15 miles

                                 3600 sec = x                       Cross Multiply

12x = 3600  * 0.15                                                  Combine

12x =  540                                                               Divide both sides by 12

12x/12 = 540/12

x = 45 miles / hour
