Answer:
Slama paid $17.40
Step-by-step explanation:
70% off of $58 would be only $17.40 because $58 x .3 = $17.40
The <u>correct answer</u> is:
<span>A) Yes, the points shown on the line would be part of y = 0.5x.
Explanation:
Looking at the graph, the line goes through (0, 0). If x=0, we have
y=0.5(0)=0.
This is the y-coordinate of the point, so it goes through this.
The equation for this line is in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. In this equation, m=0.5 and b=0. This means the slope is 0.5 or 1/2; since slope is rise/run, this means the line rises 1 for every horizontal increase of 2.
This means starting from (0, 0), we would go up 1 and over 2, creating the point (2, 1). Looking at the graph, the line goes through this point.
Next we would go up 1 and over 2 again, to (4, 2). Again, the line goes through this point.
We could follow all of the points on this line and they all fit.</span>
Let
b1-------------> base <span>△ABC
b2-------------> base </span><span>△DEF
A1-----------> area </span>△ABC
A2-----------> area △DEF
we know that
h1=20 in
h2=24 in
A1=b1*20/2-------------> A1=10b1
A2=b2*24/2 ------------> A2=12 b2
if <span>△ABC∼△DEF
</span>then
b1/20=b2/24------------> b1=b2*[20/24]-----> b1=b2*[5/6]
<span>What is the ratio of the area of △ABC to the area of △DEF?
</span>A1=10b1
A2=12b2
A1/A2=(10/12)*(b1/b2)-------> (10/12)*(b2*(5/6)/b2)-----> (10/12)*(5/6)=50/72
A1/A2=50/72--------> 25/36
the answer is (25/36)
