Answer:
36
Step-by-step explanation:
There are 30 red marbles and the ratio of black to yellow is 4/5, so 4/5=orange/green=orange/30.
30 is 6 times 5, so black=6 times 4=24. There are 24 black marbles.
Total of black and yellow=24+30=54.
40% of the marbles are green so 60% are black/yellow. Also 60% is 54 marbles.
60% is 60/100=3/5 so 3/5 of the total is 54 marbles, therefore 1/5 is 54/3=18 and 2/5 is the number of red marbles=2 times 18=36 red marbles.
to be honest i can't think of anything original for the visual thing, but i think the pi chart from the person above me would work well
Answer:
360 degrees total, 90 degrees each
Step-by-step explanation:
a rectangle's angles add up to 360 degrees, so if you divide 360 by 4, each angle is 90 degrees and all right angles are equal to 90 degrees
SA=4pir^2
d/2=r
8/2=4
r=4
SA=4pi4^2
SA=4pi16
SA=64pi in^2
if want, aprox pi=3.14
SA=200.96 in^2
For this case you can write a weighted average expression to find the average number of tickets sold per child.
We have then that an expression that can represent this average is the following:
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
answer
an expression for the average number of tickets sold per school child is
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
Answer:
$14
Step-by-step explanation:
6 attendees divided by the cost of 12 = $2 per attendee
If 7 attendees are joining times $2 per person =$14
