Sean reads his book by what speed
This answer is quite unorthodox
LIke a speed question. We will find the amount of pages Sean read per hour or minutes if u want to convert
So speed of reading = amount of pages read/ time
= 144/3 hours or 144/3*60 minutes
=48 or 8/10 minutes
So time taken to complete his book at the same pace he is reading
amount of pages to read/speed of reading
=264/48 or 264*10/8
=5.5 hours or 330 minutes
hope u understood
Answer:
C i think
Step-by-step explanation:
Because length × width × height and when you multiply you get 4.5 or 4 1/2
im so sorry if i'm wrong
Answer: 11:50
Step-by-step explanation:
Ok, la manecilla de los minutos apunta al numero X.
si la ora es Y, entonces Y + X = 12:00
podemos asumir que Y es 11:y
y es la cantidad de minutos despues de las 11, es un numero entre 0 y 59 (por que una hora solo puede tener 60 minutos)
Si la manecilla de los minutos apunta al numero 6 por ejemplo, entoces:
y = 11:30 y X = 6 min
X + y = 11:30 + 0:06 = 11:36
Así funciona.
la equacion es:
y = 5*X
y tambien queremos que:
X + y = 60min
reemplazo y por lo de la equacion de arriba:
X + y = X + 5*X = 6X = 60min
X = 10
Si la manecilla apunta al 10, tenemos que:
y = 11:50 y X = 10min
y + X = 11:50 + 0:10 = 12:00
Entonces podemos concluir que la hora es 11:50.
This is a doozy so pay attention. First thing you have to recognize is that is a trig identity, the sum identity for cosine to be exact. That formula is
.
So that means you need to find the cosine of alpha and the sin of beta. We are given the sin of alpha being 4/5 in the first quadrant. If you set up the sin ratio which is side opposite over hypotenuse of a right triangle, you put the 4 on the side opposite the reference angle, alpha, and the hypotenuse of 5 on the terminal ray and then you have to find the missing side of the right triangle you created. Using Pythagorean's theorem, you find that the missing side, which is the adjacent side to alpha, is 3. Now you can find the cosine of alpha as well, since cosine is the side adjacent, 3, over the hypotenuse, 5. So far wwe have
and
for that first angle. Now moving on to the second angle. The cosine of beta is side adjacent, 5, over the hypotenuse, 13, and we are missing the side opposite the reference angle beta. Using Pythagorean's theorem again to find the side opposite, we have that that side measures 12. Now we can find the sine of beta using that opposite side, 12, over the hypotenuse, 13. What we have now is
and
. According to the identity, we have to multiply those ratios now:
.
When you do that you get
.
Of course in order to subtract those 2 fractions you need a common denominator which is 65 so
which gives you a final answer of 
which is the first choice given above. There you go!
