Evaluate for x=2 and y=3: x^2y^-3/x^-1y

Mathematics
1 answer:
Artemon [7]3 years ago
4 0

Answer:

8/81

Step-by-step explanation:

It's most efficient to simplify the quotient algebraically before inserting the values of the variables x and y.  

The given expression reduces to x³ / y^4.

Substituting 2 for x and 3 for y, we get:

 (2)³           8

--------- = ---------- (Agrees with first given possible answer)

 (3)^4         81

It is recommended that an adult drink 64 fluid ounces of water every day.Josey has already consumed 700 millitiers of water. How
Rudiy27
In the given question it is already mentioned that an adult drinks 54 fluid ounces of water daily. Also it is mentioned that Josey has already drank 700 milliliters of water.
Now fopr solving this problem we have to fist convert 64 ounces to liter and then convert 700 milliliter to liter and then only can we get the answer to the question.
We already know
1 ounce = 0.29 liter
64 ounce = 64 * 0.29 liter
               = 18.56 liter
So 18.56 liter is the daily recommendation for an adult to drink water
Again
1 milliliter = 0.001 liter
700 ml = 0.001 * 700 liter
           = 0.7 liter
So Josey has already drank 0.7 liters of water
Amount of water Josey still needs to drink = (18.56 - 0.7) liter
                                                                   = 17.86 liter

Find m∠QPR..........
dexar [7]

Hey there! :)

Answer:

m∠QPR = 25°.

Step-by-step explanation:

Given:

m∠QPS = 40°

m∠RPS = 8x + 7°

m∠QPR = 9x + 16°

m∠QPS = m∠RPS + m∠QPR, therefore:

40° = 8x + 7° + 9x + 16°

Combine like terms:

40° = 17x + 23°

Subtract 23° from both sides:

17° = 17x°

Divide both sides by 17:

x = 1°

If m∠QPR = 9x + 16°, substitute in 1 for 'x':

9(1) + 16 = 9 + 16 = 25°.

5^3+5-6(4)<br><br> HELP FAST I’M IN CLASS
vodomira [7]

To solve: 5^3+5-6(4)

5^3+5-6(4) < first step, 5 to the third power is 125

125 + 5 - 6(4) < next step, 6(4) or 6 x 4 is 24

125 + 5 - 24 < third step, add/subtract based off what comes first.

130 - 24 < final step. 130 - 24 = 106

106 is your final answer.
