Divide the sides of the larger triangle by the corresponding side of the smaller one:
18/7.2 = 2.5
Figure A is 2.5 times the size of figure B
The scale factor is 2.5
Answer:
<h2>x = 114</h2>
Step-by-step explanation:
0.2x – 1.8/5 = 4.2
0.2x - 1.8 = 4.2 (5)
x =<u> 21 + 1.8 </u>
0.2
x = 22.8 / 0.2
x = 114
Here r ur terms : (9x^2) , (-5x) , (-7)......so there r 3 terms
constant : a number by itself...no variables....so ur constant is -7
Using the principle of proportional relationship, the amount of weight lost by hedgedog in 120 days is 3.6 oz
<u>Proportional</u><u> </u><u>relationships</u><u> </u><u>are</u><u> </u><u>defined</u><u> </u><u>thus</u><u> </u><u>:</u>
- y = kx
- <em>k</em><em> </em><em>=</em><em> </em><em>constant</em><em> </em><em>of proportionality</em><em> </em>
Taking a piar of points :
-0.24 = 8k
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>8</em>
(-0.24/8) = k
k = - 0.03
Hence, hedgedog loses weight at a rate of - 0.03 oz per day.
<u>The</u><u> </u><u>amount</u><u> </u><u>of</u><u> </u><u>weight</u><u> </u><u>lost</u><u> </u><u>in</u><u> </u><u>120</u><u> </u><u>days</u><u> </u><u>:</u>
The proportional relationship = y = - 0.03x
<em>Substitute</em><em> </em><em>x</em><em> </em><em>into</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em>
y = -0.03(120)
y = - 3.6 oz
Therefore, the amount of weight lost in 120 days is 3.6 oz.

Answer:
Your answer is 0 (zero).
<u>Step</u><u> </u><u>by</u><u> </u><u>Step</u><u> </u><u>Explanations</u><u>:</u>
<u>For</u><u> </u><u>mean</u><u>:</u>
1. Add all the numbers; which is 90
2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15
3. Your mean is 15
For Median:
1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22
2. Find the middle number(s), which are 12 &18
3. Add; 12 + 18 = 30
4. Divide; 30/2 =15
5. Your Median is 15
So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0
