Answer:
36
16 + 16 = 32
32 + 32 = 64
Thats 4 16's
64 x 9 (since 36/4 = 9) = 576
Step-by-step explanation:
Answer:
40 students would choose rap. Hope this helps! BTW nice job scaring people off
It is 40 because the total in the graph is 50 so you have to multiply everything by 4
X+y = 4, -----> y=4 - x
x² +(4-x)² =16
x² +16-2*4x+x² =16
2x² - 8x = 0
x(2x-8) = 0
2x-4=0, 2x=8, x=4
x=0 or x=4
If x=0, y=4-x=4-0=4.
If x=4, y= 4-x=4-4=0.
(0,4) or (4,0)
Check
x² +y² =16
For (0,4)
0²+4² =16
16 =16 True
For (4,0)
4² +0²=16
16=16 True
Answer (0, 4) and (4,0).
<h3>Given</h3>
burned : unburned = 1 : 3
<h3>Find</h3>
burned/total as a percentage
<h3>Solution</h3>
burned : total = burned : (burned + unburned) = 1 : (1+3) = 1 : 4
As a fraction, this is 1/4 = 0.25 = 25%
25% of the total cookies were burned.

"%" is a fancy way to write "/100". You know from place value that 0.25 (twenty-five hundredths) is 25/100, so that can also be written as 25%.
