Answer:
100
Step-by-step explanation:
Ratio is a fraction, so ratio of boys to girls would be written as [let boys be "b" and girls be "g"]:
Also, there are 250 more girls than boys, so we can write:
g = 250 + b
Lets substitute this into "g" of the ratio we wrote and cross mulitply and solve for b:
The number of boys = 100
Answer:
3/20 is the answer.......
Answer:
The answer is: the second one
Step-by-step explanation:
(2x + 2)/y = 4w + 2
pass y to the right side 2x + 2 = y(4w + 2)
expand 2x +2 = 4wy + 2y
pass 2 to the right 2x = 4wy + 2y -2
pass 2 to the right x = (4wy + 2y - 2)/2
simplify x = 2wy + y - 1 or = 2yw + y -1
Answer:
4 pack priced at £2.04 is the better pack
Step-by-step explanation:
2.04/4=£0.51 per roll
4.68/9=£0.52 per roll
Angle PQR=90 degrees.
cos 52=PQ/14.72
PQ=14.72 x (cos 52)
PQ= 9 cm to the nearest cm
