Answer:
20,100 I think
Step-by-step explanation:
The correct option is: B. length: 14 cm, width: 6.4 cm
<em><u>Explanation</u></em>
The actual length of Lake Superior is 350 miles and the width is 160 miles.
The scale is given as: 1 cm = 25 miles
Suppose, the length and width of the lake on the map are
cm and
cm respectively.
First, the equation according to the <u>ratio of scaled length to the actual length</u> will be....

Now, the equation according to the <u>ratio of scaled width to the actual width</u> will be....

Thus, the length and width of the lake on the map will be 14 cm and 6.4 cm respectively.
We know that
the addition rule states that
P(A or B) = P(A) + P(B) − P(A and B)
in this problem
P(A)=0.72
P(B)=0.84
P(A and B)=0.64
so
P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64
P(A or B) = 0.92
the answer is
0.92 (92%)
Answer:
Part A: Profit = 400 + 70 s, Part B : $3900
Step-by-step explanation:
Part A:
We know that the expression is: 0.2 ( 2000 + 350 s ). Using the distributive property :
Profit = 0.2 · 2000 + 0.2 · 350 s = 400 + 70 s
Part B :
The company's yearly profit when: s = 50 ( the total number of students )
P ( 50 ) = 400 + 70 · 50 = 400 + 3500 = $3900
