30/80 = 0.375(100) = 37.5%
30 is 37.5% of 80
Answer:
Pedro got 1520 base hits and Ricky got 1243.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of base hits that Pedro got.
y is the number of base hits that Ricky got.
Pedro and Ricky got 2673 base hits last season.
This means that 
Pedro had 277 more hits than Ricky.
This means that 
Replacing in the first equation






Pedro got 1520 base hits and Ricky got 1243.
The rectangle problem:
First, create some variables.
w = width
l = length
Then you know that the length is 3 times the width, so
l = 3w
The equation for perimeter is
P = 2(l+w)
Now you use substitution, substituting the 3w for l because you found that earlier.
P = 2((3w) + w)
And simplify.
P = 2(4w)
P = 8w
And you know P = 30 because they told you that.
30 = 8w
w = 15/4 inches, or 3.75 inches
Now substitute that value back into that first equation,
l = 3w
l = 3(15/4)
l = 45/4 inches, or 11.25 inches.
The dimensions are 11.25in for length and 3.75in for width.

The volleyball problem:
100 minutes of stretching and scrimmaging combined, and you know 10 have to be stretching, so 90 is scrimmaging.
s = scrimmaging
T = total time
s = 2/3T (they gave you this)
90 = 2/3T
T = (90*3)/2
T = 270/2
T = 135 minutes, or 2 hours and 15 minutes.
Vectors are elements of the vector space, and they can be illustrated by diagrams.
<h3>How to draw the vector 2u - 1/3v</h3>
The vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:


See attachment for the graphs of y1 and y2.
Next, we have:

So, we have:

The above expression means that, we add the vectors y1 and y2 to get vector y
