so is it 36.07 or 36.08

Answer:

36.08

Step-by-step explanation:

Side DE is the side adjacent to ∠D.  Side DF is the hypotenuse of the triangle.  Adjacent/hypotenuse is the ratio for cosine; this gives us the equation

\cos{49}=\frac{x}{55}

To solve this, multiply both sides by 55:

55\times \cos{49}=\frac{x}{55}\times 55\\\\55\cos{49}=x\\\\36.07=x

Which simplified fraction is equal to 0.53 (3 repeated)?
Morgarella [4.7K]
Hello there!

Okay, I don't know if this is a "select all that apply", but I believe that answers 1, 2, and 3 are all equivalent to 0.53.

To see how these fractions are equal, I divided the numerators by the denominators. For instance, you could have 4 over 5 (4/5) and divide 4 by 5 (4/5) to get 0.8. Now you'll do the same thing for the fractions given

24/45=0.533...
8/15=0.533...
48/90=0.533...
5/9=0.5556

As you can see, the only fraction that doesn't equal 0.53, or the outlier, is 5/9 or 0.5556

I hope this helps you out!

help please !!!Kevin wants to make a mixture that is 50% lemon juice and 50% lime juice. How much 100% lemon juice should he add
Liula [17]
So basically, he wants to make mixture where lemon=lime

it is 6 gallons so
40% of 6=0.4 times 60=2.4=lemon
60% of 6=0.6 times 60=3.6=lime
so to make them equal
3.6-2.4=1.2
he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime

1.2 gallons is the answer

See Explanation

Step-by-step explanation:

\frac{mass \: of \: earth}{mass \: of \: human}  =  \frac{5.97 \times  {10}^{24} }{6.35 \times  {10}^{1} }  \\  \\  = 0.94015748 \times  {10}^{24 - 1}  \\  \\  = 0.94015748 \times  {10}^{23}  \\  \\  = 9.4\times  {10}^{22}   \\  \\  \therefore \: mass \: of \: earth  \\ =( 9.4\times  {10}^{22} )  \times mass \: of \: human
