2\frac{3}{4}+3 \frac{5}{8}=6\frac{3}{8}

Solution:

Given expression is 2\frac{3}{4}+3 \frac{5}{8}.

To simplify the expression 2\frac{3}{4}+3 \frac{5}{8}.

Let us first convert the mixed fraction into improper fraction.

2\frac{3}{4}+3 \frac{5}{8}=\frac{(2\times 4) + 3}{4}+ \frac{(3 \times 8)+5}{8}

            =\frac{8+ 3}{4}+ \frac{24+5}{8}

            =\frac{11}{4}+ \frac{29}{8}

Take LCM for the denominators (LCM of 4, 8 = 8) and make the same.

            =\frac{11\times2}{4\times 2}+ \frac{29\times1}{8\times1}

            =\frac{22}{8}+ \frac{29}{8}

            =\frac{51}{8}

Now, divide 51 by 8 and again write it in the mixed fraction.

             =6\frac{3}{8}

2\frac{3}{4}+3 \frac{5}{8}=6\frac{3}{8}

Hence, the simplified answer is 6\frac{3}{8}.

Answer:

4

Step-by-step explanation:

Is that a log with the base of   3√(2)  ?

If so....my calculator says the answer is   4

Let's see if we can do it w/ou the calculator:

3 sqrt(2)^x = 324 =  3^4 * 2^2     Now 'LOG' both sides:

x log (3 sqrt 2)  =   log (3^4 *2^2)  =  4 log ( 3 * 2^(2/4)) = 4 log (3 sqrt2)

                       now divide both sides by log (3 sqrt2 )

  x = 4        (If I did the math correctly ! )

Please help with 1-9<br> 43 points
Paul [167]

Remark

I'll do two from each group, leaving you with 1. I just leave the answer for the one I don't do or a hint it it is long. That's more than we are instructed to do (which is three parts per posted question).

One

Two ratios form a proportion because they both equal the same thing when you reduce them to the point where the ratios are prime to each other.

3/4 = 12/16

3/4 can't be reduced any further. When both 12 and 16 are divided by 4, the result is 3/4

Two

<em><u>Formula</u></em>

Sale Price/Original Price = 3/4

<em><u>Solve</u></em>

Sale Price / 64 = 3/4           Multiply both sides by 64

Sale Price = (3/4)*64

Sale Price = 48

Three

682 Trillion atoms of hydrogen.

Four

<em><u>Formula</u></em>

rotations / 40 seconds = rotations / second

<em><u>Solve</u></em>

2000 / 40 seconds = rotations / 1 second    Just divide

50 rotations/1 second = rotations / second.

Five

<em><u>Formula</u></em>

Herd of cows / Total pounds of milk = 1 cow / pounds of milk

<em><u>Given</u></em>

Herd = 12

pounds total = 224998

<em><u>Solve</u></em>

12/224998 = 1 / x             Cross multiply

12x = 224998

x = 18750 pounds of milk for 1 cow.

Six

0.5 m in 1 second.

Seven

<em><u>Formula</u></em>

Pages / hour = pages / minute

pages / hour = 4.5

1 hour = 60 minutes.

<em><u>Solve</u></em>

4.5 / 1 hour. But 1 hour = 60 min

4.5 pages / 60 min = 0.075 pages per minute.

Note this is not a true proportion. You just have to know how it is done.

Eight

This is also not a true proportion. The best way to do this is called unit analysis.

\dfrac{18feet}{2seconds} * \dfrac{1 mile}{5280 feet}\dfrac{3600sec}{1hour}

Each set of units on the right will cancel with a set of units on the left until all that you area left with is miles / hour. Then just multiply the numerator numbers together and denominator numbers together.

numerator: 18 * 1 * 3600 = 64800

denominator: 2 * 5280 * 1 = 10560

Now divide the numerator by the denominator.

answer: numerator/denominator = 64800/10560 = 6.14 miles per hour.

Nine                                              

Note: there are 1760 yards in a mile.

1 gallon will take you 32000 yards or 18 miles. Do this the same way eight was done.
