Step-by-step explanation:
By Pythagoras' Theorem, 6^2 + 8^2 = x^2.
x^2 = 36 + 64 = 100, x = 10.
15/50 * 2/2 = 30/100
Now you can easily see decimal and percent form
Decimal: 0.30
Percent: 30 percent
Answer:
Step-by-step explanation:
3 in 340,500 is 300,000
and 3 in 316 ,000 is 300,000
so 300,000-300,000 = 0
You are doing the distributive property.
68.5j+76.54
Answer:
and 
Step-by-step explanation:
At=As+Ar; A=b.h and
, then: At=(x+120)x so
(x+120)x=4500,
Applying cuadratic equation formula:
