Answer:

The GCF is going to be 20

Step-by-step explanation:

This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here

The prime factorization of 20, 2 × 2 × 5= 20

The prime factorization of 80, 2 × 2 × 2 × 2 × 5 = 80

The common factors are 2, 2, and 5. We multiply those to get the GCF.

2 × 2 × 5 = 20

(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

If sine theta equals negative square root of three over two and pi less than theta less than three times pi over two, what are t
Romashka-Z-Leto [24]

Cosine theta equals the negative square root of three over two; tangent theta equals the negative square root of three over three is the correct answer.

<h3>What is angle measurement?</h3>

An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry. A protractor is used to measure angles in degrees (°).

Given data;

sin(1/2) = π/6

The value of the trignometric function are;

cos(π/6) = (√3)/2

tan(π/6) = 1/√3 = (√3)/3

In the second quadrant, where the cosine and tangent signs are both negative, is the angle of interest.

θ = 5π/6

cos(5π/6) = -(√3)/2

tan(5π/6) = -(√3)/3

Hence. cosine theta equals the negative square root of three over two; tangent theta equals the negative square root of three over three is the correct answer.

To learn more about the angle measurement, refer to the link;
