It is not a very tough question as it has all the information's required to find the necessary answer. It is already given that 82 1/2% of a certain number is 330. It is required to find the unknown number. So we have to create an equation with a single unknown number.
Let us assume the number to be = x
then we can easily write the equation as given below.
82 1/2% x = 330
(165/4)%x = 330
(165/400)x = 330
x = (330 * 400)/165
= 2 * 400
= 800
So the unknown number is 800.
Answer:
<h2>
$14.00</h2>
Step-by-step explanation:
3.50 x 400%
400% = 4
3.50 x 4 = 14.00
We have that
y = 225-16t²
we know that
<span>the ball hit the ground when y=0
the point when y=0 is the x intercept of the graph
so
find the value of t for y=0
y=0
</span>y = 225-16t²------> 0=225-16t²
16t²=225-------> t²=225/16----------> t=√(225/16) -----> t=15/4 sec
t=3.75 sec
the answer is
t=3.75 sec
see the attached figure
Answer:
8
Step-by-step explanation:
from the graph, we can see that when x = 1,
f(1) = 10 and g(1)= 2
hence
f(1) - g(1) = 10 - 2 = 8
