Percent decrease : (original number - new number) / original number...x 100
percent decrease = (25 - 18) / 25....x 100
percent decrease = 7/25 * 100
percent decrease = 700/25 = 28%
Answer:
450L
Step-by-step explanation:
This is a ratio and proportion problem. First you need to determine the known ratio and the unknown ratio. In this case we have the known ratio:

The unknown ratio in this case is:

So to do this, we just set up the proportion and solve for it:

Okay so, I am assuming the model is smaller so it would be 0.34m long.
The model has to be 200 times smaller than the actual plane
Divide 68/200 and you get 0.34
Then to check your answer, multiply 0.34 by 200 which is 68 meaning
0.34:68 is equal to 1:200
Assuming the model is bigger (just in case) it would be 13,600m long.
The in this scenario, the model has to be 200 times bigger so it would be 68(200) which is 13,600
Hope this helps
x = 2 and y= 1
y = 3x-5
1= 3 x 2 - 5
1= 6-5
1=1
6x+3y=15
6 x 2 + 3 x 1 = 15
12+3=15
15=15

<h2>
The equation for a horizontal plane through the point (−4,0,−3) is z = -3</h2>
<u>Solution-</u>
Let's assume n is the normal vector for the horizontal plane < 0, 0, 1 > .
The co-ordinate of the point is (-4, 0, -3)
The general equation of a plane is -




∴ The equation for a horizontal plane through the point (−4,0,−3) is z= -3
