Evaluate 6+4/a +b/3 when a = 4and b=3

tester [92]

If , a = 4 and b = 3

Then :-

$= 6 + \frac{4}{4} + \frac{3}{3}$

$= 6 + \frac{(4 \times 3)}{12} + \frac{(3 \times 4)}{12}$

$= 6 + \frac{(12 + 12)}{12}$

$= 6 + \frac{2}{1}$

$= 6 + 2 \\$

$= 8$

$∴6 + \frac{4}{4} + \frac{3}{3} =8$

At a local carnival, Mia is shooting at a row of 10 duck targets. Each time she shoots at a duck, the duck she shoots and any du

zubka84 [21]

Using the combination formula, it is found that she can shoot the ducks in 120 ways.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, 3 ducks will be shoot from a set of 10, hence:

$C_{10,3} = \frac{10!}{3!(10-3)!} = 120$

Thus, she can shoot the ducks in 120 ways.

Out of 75,000 voters in a constituency 65%

serious [3.7K]

<h3>Answer:</h3>

$\large\boxed{35\%\,\text{did not vote;}\,48,750\,\text{voted}}$

<h3>Step-by-step explanation:</h3>

In this question, we're trying to find the amount of people that did not vote and the percentage of people that didn't vote.

We know that 65% of people voted and percents are out of 100%.

We would subtract 65 form 100 to get out percentage that didn't vote.

$100-65=35$

35% of people didn't vote.

Now, we can solve the next question.

A total of 75,000 people voted. What we're going to have to do is find how much of 75,000 is 65%.

We would do this by multiplying 75,000 by 0.65

$75,000*0.65=48,750$

This means that 48,750 people voted.

A plane set off to burbank at a speed of 215 mph.On the return flight of 13 hours, the plane cruised at 237 mph. How many hours

bearhunter [10]

It seems you need 2 equations:

We first must solve for: distance = rate * time

Using return flight data: distance = 237 * 13 = 3,081 miles

Then, using flight TO Burbank data: time = distance / rate

time = 3,081 / 215 time = 14.3302325581 hours
