If Adrianna can read 7 pages in 10 minutes. At this rate, how many page can she read in 25 minutes?
lesya692 [45]

3.5 : 5

7 : 10

14 : 20

17.5 : 25

At that rate, she can read 17.5 pages in 25 minuets.

Divide both 7 and 10 by 2, which gets 3.5 and 5

5 * 5 = 25

5 * 3.5 = 17.5

Therefore, in 25 minuets, she can read 17.5 pages.

Answer:

C. 0.23°

Step-by-step explanation:

We are given

r=\frac{1}{32}v^{2}sin(2\theta)

Re-arranging this equation (multiply by 32 on both sides and divide by v^{2} on both sides gives us:

\frac{32r}{v^{2}}=sin(2\theta) or

sin(2\theta)=\frac{32r}{v^{2}}

Substituting for, r and v we get

sin(2\theta)=\frac{(32)5000}{4500^{2}}=0.00792\\\\\theta=sin^{-1}(0.0079)=0.4527\\\\\theta=\frac{{0.4527}}{2}=0.2263\approx0.23
