Always place it out of 9. For example, 0.333= 3/9, or if simplified, 1/3.
0.5555? this will be 5/9.
for the other way around, make it a repeating decimal, such as 4/9, make that 0.444
If it is 33/99, or even 333/999, the rule should be the same.
Answer:
(a) Circle Q is 9.4 units to the center of circle P
(b) Circle Q has a smaller radius
Step-by-step explanation:
Given
Solving (a): The distance between both
The equation of a circle is:
Where
P and Q can be rewritten as:
So, for P:
For Q:
The distance between them is:
Where:
--- 
--- 
So:
Solving (b): The radius;
In (a), we have:
--- circle P
--- circle Q
By comparison
<em>Hence, circle Q has a smaller radius</em>
Answer:
<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
Step-by-step explanation:
We need to find the unit rate. This found by dividing the price by the number of bananas so we get the price for 1 pound of bananas.
$1.97/5 = $0.39
$1.05/3 = $0.35
<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
Frac. = 7/200
Dec. = 0.035
Answer:
A.
Step-by-step explanation:
< means open circles
x-21<3 x≥21
-x+21<3 x<21
18<x<21 and 21≤x24
so the union of will be 18<x<24
