(5/8)+(2/5)= 

so you need a common den so in this case its 40

so we multiply to get 40 like

(5/5)(5/8)+ (2/5)(8/8)=

25/40 + 16/ 40 = 41/40

In ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45. What is the value of the cosine of ∠X to the nearest hundredth?
kotegsom [21]

The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.

Step-by-step explanation:

The given is,

                   In ΔWXY, ∠Y=90°

                        XW = 53

                         YX = 28

                        WY = 45

Step:1

             Ref the attachment,

             Given triangle XWY is right angled triangle.

             Trigonometric ratio's,

                              Cos ∅  = \frac{Adj}{Hyp}    

             For the given attachment, the trigonometric ratio becomes,

                              Cos ∅  = \frac{XY}{XW}.....................................(1)

             Let, ∠X = ∅

             Where, XY = 28

                         XW =  53

             Equation (1) becomes,

                                 Cos ∅  = \frac{28}{53}

                                 Cos ∅ = 0.5283

                                        ∅ = cos^{-1} (0.5283)

                                        ∅ = 58.109°

Result:

          The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.

How to simplify 6 to the power of -1 over -8 to the power of 0
neonofarm [45]

Answer:

\frac{1}{6}

-8 to the power of 0 = 1

(Anything to the power of 0 = 1)

and 6 to the power of -1 = 1/6

( Any number to the power of a negative number will become a fraction)

Example.

5^{ - 3}  =  \frac{1}{5^{3} }

So is will be 1/6 over 1

Which gives you your final answer.

My sister is 2 years older than I am. The sum of our ages is 32. Find our ages.
VikaD [51]
Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30 
x = 15

Your age is 15 and your sisters is 17

<span>Hope This Helps You!
</span>Good Luck Studying :)

I seriously need help.
Leni [432]

Let's go:


y = ax + b


{5 = 4a + b

{15 = - 6a + b


{5 = 4a + b

{- 15 = 6a - b

10a = - 10

a = - 1


5 = 4a + b

4.(-1) + b = 5

b - 4 = 5

b = 9


- 1; 9


y = -1x + 9


I hope I helped you.
