Answer: 54
Step-by-step explanation:
First we add 17 plus 18 to dins total number of students I got 35
Then we make ratio
3/35
So we know we have total number of 630 kids then we make a ratio with no teacher so x
X/630
Lin both together then done ☑️
Step-by-step explanation:
The midpoint can be found with the formula.
midpoint = (x1+x2) /2 , (y1 + y2 )/2
( x1 , y1), and (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.
P = (0,0)
midpoint = (2,5)
x midpoint = 2 = (0+ x2)/2
×2 = 4
y midpoint = 5 = (y2+0 )/2
10 = y2
so the point Q is (4 , 10)
To solve this problem, you must follow the proccedure below:
1. First, you must calculate the Constant of proportionality "k".
2. The problem says that t<span>he number of days needed to remodel a house varies inversely as the number of people working on the job. Then:
Number of days=K/Number of people
K=(</span>Number of days)(Number of people)
18 weeks=135 days
K=135x4
K=540
3. Now, you have:
Number of days=540/Number of people
8 weeks=60 days
Number of people=540/60
Number of people=9

How many people are needed?
The answer is: 9</span>
Answer:
8
Step-by-step explanation:
32 + 72 = 13x
104 = 13x
x = 8
