Answer: 44%
Step-by-step explanation: First, let's add up all the children in the classroom...
15 + 12 = 27
There's 15 boys, therefore have to divide 15 by 27...
15 ÷ 27 = 0.55 x 100 = 55%
Now, let's divided the total amount of girls...
12 ÷ 27 = 0.44 x 100 = 44%
44 + 55 = 99%
The perecent of girls in the classroom are 44%, I hope this helps!
1 1/2 pounds
16 ounces = 1 pound
8 1/4 pounds = 132 ounces
132 ounces/ 6 cakes = 22
22 ounces = 1 1/2 pounds
Let s = the speed of the slower train in km/hrs+10 = the speed of the faster train in km/hrLet t = time in hrs for the slower train to go 160 kmt-5 = time in hrs for faster train to go 160 km---------------Slower train:(1)
160=s.t
Faster train:(2) 160=(s+10) .(t-.5)From (1)(1) t=160/s
use the relations given in following screenshot and then use quadratic equation.
Answer:
yes it can be improved by learning so dont ask any tholing
F(x) = 50x
independent variable = x
dependent variable = f(x)
f(x) = 50x......find f(6)
f(6) = 50(6)
f(6) = 300
