Answer:
Jessica has $13,80 and Sarah has $58.20.
Step-by-step explanation:
Let j be the amount of money that Jessica has.
Let s be the amount of money that Sarah has.
s + j = 72
Since Sarah has 3 more than 4 times what Jessica has...
s = 4j + 3
So 4j + 3 + j = 72
5j = 69
j = 13.8
So Jessica has $13,80.
Therefore Sarah has $58.20.
Answer: The true statement is (A) P(extra large)≈0.25.
Step-by-step explanation:
Given that a piece of paper is randomly selected from a stack that contains 15 small, 44 large, and 20 extra large pieces.
We are to select the true statement.
Let S be the sample space for the experiment of choosing a piece.
Then, n(S) = 15 + 44 + 20 = 79.
Let A, B and C denote the events of choosing a small piece, a large piece and an extra large piece respectively.
So, n(A) = 15, n(B) = 44 and n(C) = 20.
Therefore, we have
Thus, the true statement is P(extra large)≈0.25.
Option (A) is correct
Answer:
its 136
Step-by-step explanation:
Answer:
The scale factor of the smaller rectangle to the larger rectangle is 3/2
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem
To find out the scale factor of the smaller rectangle to the larger rectangle. set up a proportion
----> ratio of corresponding heights
or
----> ratio of corresponding bases
therefore
The scale factor of the smaller rectangle to the larger rectangle is 3/2
