Answer:
3
Step-by-step explanation:
The product of 3.99 and 3.3 will have 3 decimals.
When multiplying decimals, you add the decimals to get the total number of decimals in your product.
2+1=3 so it will have 3 decimals.
Answer:
.9
Step-by-step explanation:
If the number behind that place is 5 or greater than you round up one but if it is 4 or below than you keep the number the same.
So 90^2+90^2=c^2
8100+8100=c^2
16200=c^2
C= ~127.28
We want to see which could be the possible score of Kath for the given information. We will find the inequality:
K ≤ 33
<h3>
Stating what we know:</h3>
The given information is:
- The sum of the scores is not greater than 55 points
- Ella's score is 22 points.
<h3>Writing the inequality:</h3>
First, we need to define the variable K for Kath's points, because of the given information, we can write the inequality:
K + 22 ≤ 55
This means that the sum of the points is smaller than or equal to 55.
Now we just need to solve this for K, to do this, we subtract 22 in both sides:
K ≤ 55 - 22
K ≤ 33
From this, we can conclude that Kath has at most 33 points.

Answer:
X+y=30
X=30-y
Z=yx
Z=y(30-y)
D/dy
z=30–2y
At max 30–2y=0
2y=30 Y=15
Therefore x=15
