Answer:
3 1/3 gallons per minute
Step-by-step explanation:
We can use ratio's to solve this problem. We will put gallons on top and time on the bottom
5/6 gallons x gallons
-------------------- = -------------
1/4 minute 1 minute
Using cross products
5/6*1 = 1/4 x
Multiply by 4 on each side
5/6 * 4 = 1/4 *4 x
20/6 = x
Dividing the top and bottom by 2
10/3 =x
Changing this back to a mixed number
3 goes into 10 3 times with 1 left over
3 1/3 gallons per minute
okay well first you should put it in slope-intercept form aka y = mx + b
but you have simplify everything first
2(x + 3) + 2(y + 2) = 16
2x + 3 + 2y + 4 = 16
2x + 2y + 7 = 16
-7 -7
2x + 2y = 9
-2x -2x
2y = -2x + 9
/2 /2
y = -x + 4.5
so now in a graph it should look like this:
Answer:
A 40
Step-by-step explanation:
We can find angle K
J + K + L = 180 The angles of a triangle add to 180
50 + K + 90 =180
140 +K = 180
Subtract 140 from each side
140-140 + K = 180-140
K = 40
Since the triangles are congruent
J = P
K = N
L = M
We want to find N
K = N = 40
K = N

In the given question it is important to take note of every minute details that are given in the question. using these details the answer to the given question can be easily reached.
Let us assume the common ratio to be x.
Then
x + 9x = 81
10x = 81
x = 81/10
= 8.1
A s we already know that the ratio of chaperones to students is 1:9
Then
The number of chaperones = 1 * 8.1
= 8.1
So 8.1 chaperones were there in total. I hope you have got the answer you were looking for.
