Answer:
<h2>A. $97.50</h2>
Step-by-step explanation:
<h3>Step 1: Add all the numbers together</h3>
123 + 89 = 212
56 + 33 = 89
<h3>Step 2: Multiply</h3>
212 x $0.25 = $53.00
89 x $0.50 = $44.50
<h3>Step 3: Add</h3>
$53.00 + $44.50 = $97.50
Answer is a. $97.50
I'm always happy to help :)
Answer:
hello some information related to your question is missing
answer : The pattern discovered supports the hypothesis that taller customers have larger shoe sizes but with some exceptions and this exceptions are ; at Height 5ft 10 inches two people are seen to have different shoe sizes i.e. Eduardo with shoe size : 10.25 inches and Susan with shoe size : 10inches. another exception from the pattern is Lily having a height of 5 ft and shoe length of 9 inches .
Step-by-step explanation:
From the data given the pattern discovered supports the hypothesis that taller customers have larger shoe sizes but with some exceptions and this exceptions are ; at Height 5ft 10 inches two people are seen to have different shoe sizes i.e. Eduardo with shoe size : 10.25 inches and Susan with shoe size : 10inches. another exception from the pattern is Lily having a height of 5 ft and shoe length of 9 inches .
(1/4)*(8/1)
(1*8)/(4*1)8/42 miles
Ratio of student to teacher = 17:3
Let the total number of students and faculty = x
Then
Number of students = 17X
Number of teachers =3X
So
17X+3X=740
20X = 740
X = 37
Then the number of students = 17*37
<span>
= 629</span>
Number of teachers = 3*37
<span>
=111 </span>
Answers:
- rate of the plane in still air = 770 km per hour
- rate of the wind = 130 km per hour
=================================================
Explanation:
p = speed of the plane in still air (i.e. without any wind)
w = speed of the wind
---------
If the plane flies against the wind, then it slows down from p to p-w
distance = rate*time
3200 = (p-w)*5
3200/5 = p-w
p-w = 640
p = 640+w
---------
If the plane flies with the wind, then it gets a speed boost going from p to p+w
distance = rate*time
6300 = (p+w)*7
6300/7 = p+w
900 = p+w
Now plug in p = 640+w and solve for w
900 = p+w
900 = 640+w+w
900 = 640+2w
2w+640 = 900
2w = 900-640
2w = 260
w = 260/2
w = 130
The wind is moving at a speed of 130 km per hour
p = 640+w = 640+130 = 770
The plane moves at a speed of 770 km per hour if there isn't any wind.
