Answer:
60% adult
40% children
Reasoning:
Add the adults and children first.
Then find the ratios of the children and parent percentages.
16:40 children
24:40 adult
16/40=2/5=0.4=40% children
24/40=3/5=0.6=60% adult
H=150cm
Because these rectangles are similar then they can be dilated to get to the same size as the other.
First you want to find what the scale factor (dilation degree) from the big rectangle to the small. So to do this you want to but your SMALLER value on the top while the BIGGER value on the bottom of your fraction to find the scale factor. This would then look like 60/84. You could simplify this fraction to 5/7.
You can then use this fraction to multiply by the other side of the big rectangle so that you find h. 210*5/7=1050/7. When this is simplified you will get 1050/7=150
Answer:
A parabola has the form:
y = a*x^2 + b*x + c
Where a is the leading coefficient.
If a is positive, the parabola opens up.
If a is negative, the parabola opens down.
a is the factor that multiplies the part that grows the fastest in the equation, thus, if a is a larger value (in absolute value) then the parabola will grow faster (then the parabola will be narrow)
if a is smaller (again, in absolute value) the parabola will grow slower, then the parabola will be wider.
With this, we can conclude that:
a = -4
is the largest value of a in absolute value.
Then this corresponds to the thinner parabola (the one at the left)
a = -1
Is the middle value of a, then this corresponds to the graph of the middle
a = -0.25
Is the smallest absolute value of a, then this one corresponds to the widest graph (the first one at the left)
