Answer:
36cm^2
Step-by-step explanation:
total area: 6x(4+3)=42
total area excluding the space: 42-(2x3)=36
3-----4
3-----4
3-----4
Total (Left): 9
Total (Right): 12
-------------------
Total (Left) + Total (Right) = 9 + 12 = 21
The constant is 36
because direct variation y/x
Answer:
The model is made in a<u> 1:40 ratio
</u>
Step-by-step explanation:
How many times is 4 multiplied to be equal to 160?
4(x) = 160
X = 160 / 4
<u>X = 40</u>
The proportion, rate, and ratio are almost the same.
They represent the correspondence between the parts and the whole since they all express a binary relationship between the quantities, that is, objects, people, tablespoons.
If the ratio is 1: 2 it could be read that for every 1 there are 2.
For example 1: 2 cups; For every cup of something there are 2 cups of something else.
In this case, 1:40; For every inch of the model, there are 40 feet in the playground.
Answer:
<h2>A) y= -x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line<em>:</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
==========================================
We have the points (-1, 2) and (4, -3).
Calculate the slope:
Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:
<em>subtract 1 from both sides</em>
Finally:
