<h3>I'll teach you how to solve (2 5/8 +4 8/17 )+( 9/17 +3 3/8 )</h3>

--------------------------------------------------------------------------

(2 5/8 +4 8/17 )+( 9/17 +3 3/8 )

Convert mixed numbers to improper fractions:

(21/8 + 4 8/17)+ (9/17+ 3 3/8)

Convert mixed numbers to improper fractions:

(21/8 + 76/17)+(9/17+ 3 3/8)

Convert mixed numbers to improper fractions:

(21/8 + 76/17)+(9/17+ 27/8)

Remover parentheses:

21/8 + 76/17+9/17+ 3 3/8

9/17+ 3 3/8= 72/163

21/8 + 76/17+72/163

Adjust fractions based on the LMC:

58191/22168+99104/22168+9792/22168

Convert improper fractions to mixed numbers:

7 11911/22168

Your Answer Is 7 11911/22168

plz mark me as brainliest :)

Answer:

Step-by-step explanation:

You don't need the parenthesis, so you get:

2 5/8 + 4 8/17 + 9/17 + 3 3/8

You combine the integer values and get:

9 + 5/8 + 8/17 + 9/17 + 3/8

You combine the fractions with the denom. of 8 and do the same with those with the denom. of 17 and get:

9 + 8/8 + 17/17

You simplify:

9 + 1 + 1 =

Lou’s Shoes is having its annual Flag Day Sale and is offering a 25% discount on all regularly priced shoes. Kayla spends $13.50

patriot [66]

The easiest way to think of these is to put them in terms of percentages. Obviously, if you are SAVING 25%, you are SPENDING 75%. So if she SPENDS 13.50, we can easily use the 75% in an equation. $13.50 = .75x, with x being what the shoes cost originally. The .75 indicates that she is spending 75% of what the original cost is. You don't have any examples to pick from, but this is the best way to explain what one of the equations could be. You could also base it on money saved, but the equation is not quite as neat.

What are the sine and cosine ratios for a 30°–60°–90° triangle with a hypotenuse of 6, when θ = 60°?

Margaret [11]

Answer:

There are two ways to do this problem algebraically or trigonometrically.

Algebraically/geometrically

The ratios of the sides of a 30/60/90 tri. are x, x√3, 2x (short leg, long leg, hyp). Therefore, if the long leg is 6 'units'. then 6 = x√3. x = 6√3.

The hyp is 2x then the hypotenuse is 2(6√3) = 12√3, rationalizing is 12√3/3 = 4√3

Using Trig.

We can use sinx = y/r = opp/hyp. The long leg of 6 is opposite 60 degrees (pi/3).

Therefore, sin(pi/3) = 6/r =

r = 6/sin(pi/3) = 6/(√3/2) = 12/√3, when you rationalize you get 12√3/3 = 4√3
