Pythagoras theoram? use it here!

That is,

H² = B² + P²

H² = 15² + 4²

H² = 225 + 16

H = √241

H = 15.5

You should opt for 15.5

P.S: Best of luck for your test! ;))

Ami'yan runs every day for exercise at a rate of 1 kilometer every 15 minutes. How many meters does he run in 1 hour? - Thank yo

Alona [7]

Answer:

The total distance covered in 1 hour is 4000 meters.

Step-by-step explanation:

The distance Ami'yan runs is 15 minutes = 1 kilometer

Using the unit formula,

The distance ran in 1 minute = $(\frac{1}{15} ) \textrm{Kilometer}$

Now, 1 hour = 60 minutes

⇒The distance covered in 60 minutes = 60 x (Distance run in 1 minute)

= $60 \times \frac{1}{15} = 4$

So, the distance covered in 1 hour = 4 kilometer

1 kilometer = 1000 meters

⇒ 4 km = 4 x 1000 meters = 4000 m

Hence, the total distance covered in 1 hour = 4000 meters.

3. Let sin 21 = 0.358. What is the value of x for cos x=0.358?

r-ruslan [8.4K]

Answer:

$\cos(69)$

Step-by-step explanation:

We will use the co-function identity for sine, where:

$\sin(x)=\cos(90-x)$

Since sin(21)=0.358=cos(x). This means that:

$21=90-x$

Solve for x. Add x to both sides:

$x+21=90$

Subtract 21 from both sides:

$x=69\textdegree$

Hence:

$\sin(21)=\cos(69)\approx0.358$
