Answer:

(a^2 x^10 y^2)^(1/5)

Step-by-step explanation:

a is raised to the 2/5 power. If you put it under the 1/5 power brackets, a will squared comparred to all the other powers.

So the answer is (a^2 x^10 y^2)^(1/5)

(PLEASE HELP ) A falcon flies 800,000 meters in 4 hours. Use the formula d = rt, where d represents distance, r represents rate,

blagie [28]

Answer:

r = d/t

r = 200, 000 meters/hour

r = 200, kilometers/hour

km/ hour makes more sense

Step-by-step explanation:

Given

) A falcon flies 800,000 meters in 4 hours.

thus distance = 800, 000 meters

1 km = 1000 meters

thus distance in km= 800, 000 meters/1000 = 800 km

t = h hours

Part A: Rearrange the distance formula, d = rt, to solve for rate.

d = rt

dividing both sides by t

d/t = rt/r = r

thus. r = d/t

Part B: Find the falcon's rate in meters per hour.

d = 800, 000 meters

t = 4 hours

r = 800, 000 meters/ 4 hours = 200, 000 meters/hour

thus, rate = 200, 000 meters/hour

Part C: Find the falcon's rate in kilometers per hour.

we know d in km = 800 km as shown above

thus

rate = 800 km/4 hours = 200 km/hour

Part D: Which unit, meters, or kilometres, makes more sense to use in this scenario, and why

we know that standard unit of speed is

km/hour and m/sec

we know that that every unit is divided into from to large so that if the value is large or small we can use the appropriate unit and thus it is simpler to look the data and analyze it.

since here distance is very large , hence it is better to use km /hour

The step work of the question along with the answer

Travka [436]

Answer: $RM 31631$

Step-by-step explanation:

We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:

$RM 57000(\frac{8}{9})^{n}$

Where $RM 57000$ is the price of the car when it was bought new, and $n=5$ is the number of years the car was used.

Solving the formula with the given data:

$RM 57000(\frac{8}{9})^{5}=RM 31630.95$ This is the value of the car according to the formula.

However, this value can be approximated to:

$RM 31631$

-8x - 46 = -6x - 8
-8x + 6x = -8 + 46
-2x = 38
x = -19

The equation:
-8x - 46 = -6x - 8

The solution:
x = -19

Kesha sharpened 4 colors of pencils for her teacher. She sharpened equal amounts of red and green pencils. Then she sharpened tw

Nimfa-mama [501]

Variables are taken from the first letter of the color, ex: green = g.

Given:
r = g
2r = b = y
Total =42

So then:
r+ r + 2r + 2r = 42
6r = 42
r = 7

y = 2r
y = 2(7)
14 of the 42 pencils were yellow.
