Answer:1/30 page per minute
Step-by-step explanation:
2 1/2 pages =3/2 pages.
3/4 hrs=45 minutes
Hence the number pages he can type per minute =3/2 pages/45 minutes=3/2×1/45=1/30page per minute
You can round 49 to 50 and you can round 162 to 200.
You know that 5 * 2 = 10, so 50 * 200 must be 1000. You just add the zeroes.
Answer:
I think it is 8.9 and 9.1
Step-by-step explanation:
because
3.1 its way off so no
4.2 and 4.3 it ehh
but 4.5 and 4.6 it close
hope this helps
Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,

Also,

Comparing both we get,

It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
