Answer:
a ≈ 14 or 6
Step-by-step explanation:
264 = π × a × (20 - a)
a(20 - a) = 
≈ 84 (rounded off to nearest whole number)
Opening the brackets we get;
a² - 20a + 84 = 0
Applying the quadratic formula we get:
a ≈ 14 or 6
Answer:
Perimeter ratio: 11:6
Area ratio: 121:36
Step-by-step explanation:
The ratio of length of the perimeter of one similar figure to another is the ratio of the side lengths.
The ratio of the areas is the ratio of the squares of the side lengths.
That was said oddly. From what I understand, she would need to buy 64 feet of fabric.
Answer:
1
Step-by-step explanation:
All are divisible by 1.
Leading term is the term with the highest power (first term from left to writewhen arranged in decreasing power order)
8x^5 is higher power than 5x^4 (5>4)
so leading term is 5th degree
constant=0 degree (x^0=1)
linear=1st degree (x^1)
quartic=4th degree (x^4)
quintic=5th degree (x^5)
answer would be B
