IF JOHN RAN A 5-KILOMETER MARATHON HOW LONG WAS THAT IN METERS?

Answers

Answer 1
Answer: A kilometer is composed of 1000 meters. The term "kilo" means "a thousand."

So 5 kilometers means 5 1000 meters, thus it is equal to 5,000 meters.

1 km = 1000 meters

5 km * 1000 m / km = 5 * 1000 m = 5,000 meters

1 m = 0.001 km

5 km * 1m/0.001km = 5 m / 0.001 = 5,000 meters

XYZ is a right angle triangle.XY = 5cm
Angle Z = 32°

Calculate angle YZ.

Answers

We are given the measurement of XY which is 5cm. This is the opposite since it is opposite of the angle given. The angle is 32 degrees. Since this is a right triangle there is a simple relationship between sides and angle. In this case since we are to find YZ or the hypotenuse we are given the relationship sin(\alpha)=opposite/hypotenuse. Then the answer would be 9.44 cm. 

Simplify sin(180-x)°-sin x°

Answers

Answer:

0

Step-by-step explanation:

sin(180-x) - sin(x)

= sin(180) × cos(x) - cos(180) × sin(x) - sin(x)

= 0 × cos(x) - (-1) × sin(x) - sin(x)

= 0 + sin(x) - sin(x)

= 0

Karey is prescribed 600 mg of a medication that decays at a rate of 40% per day, d, according to the equation

Answers

Answer : 7.8%

Karey is prescribed 600 mg of a medication that decays at a rate of 40% per day, d, according to the equation

m=600(0.6)^d

Noelle takes same amount before 5 days.

Amount of medication remain in Nelle's body is

m=600(0.6)^5 = 46.656

Karey is prescribed 600 mg of a medication

We need to find out what percentage of 46.656 in 600

(46.656)/(600) =0.07776

Now multiply it by 100 to get percentage

0.07776 * 100 = 7.8%
