Answer:
yoo
Step-by-step explanation:
They have to be at least 40 abut less than 70, so 40 < (underlined) x < 70.
<span>They have to be at least 60 inches but less than 75 inches tall, so 60 < (underlined) y < 75. </span>
<span>Graph the following lines: </span>
<span>x = 40 </span>
<span>x = 70 (dotted) </span>
<span>y =60 </span>
<span>y= 75 (dotted) </span>
<span>The square the four lines make is the answer. I hoped that help!</span>
Yes, both of these ratios are proportional. You could either plug it into an equation and solve it, or do like I did and divide. If you divide 16 by 12, you get 0.75. If You divide 24 by 18, you also get 0.75, therefore they are equal. The reason why I divided by the numbers that I did is because you're trying to figure out how much it increased and if it was equivalent. They increased 0.75% of their size that they started with. I hope this helps!
