Answer: 54 flowers
Step-by-step explanation:
0.6 is 60% as a decimal
90 * 0.6 = 54
Thus, since 60% of 90 is 54 and 60% of the flowers are yellow, 54 flowers are yellow.
Answer:
(x+5)²-10x²
Step-by-step explanation:
USing the completing square method
x² +25
= (x)² +2(x)(5) +(5)² -10x²
=(x+5)²-10x²
Let x=small circle
2x = bigger circle
πx^2 + π(2x)^2 = 80π
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 16
x = +/- 4
but we need the positive one because there's no negative measurement so
the answers are:
4m and 8m
Since y must equal both 3x+2 and x-4, we deduce that 3x+2 and x-4 must equal each other. So, we have
