The correct answer is A, x-4
The race is 111.6 m long.
8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1
Add to this the distance to the first hurdle and the distance from the last hurdle:
86.1+15+10.5 = 111.6 m
Answer:
The price decreased by 16 1/3%, or approximately 16.3%
Step-by-step explanation:
Use the formula for percent change. If the answer is negative, it is a percent decrease. if the answer is positive, it is a percent increase.
percent change = (new price - old price)/(old price) * 100%
In this case, use:
new price = 50
old price = 60
percent change = (new price - old price)/(old price) * 100%
percent change = (50 - 60)/60 * 100%
percent change = -10/60 * 100%
percent change = -1/6 * 100%
percent change = -100/6% = -50/3% = -16 1/3%
The price decreased by 16 1/3%, or approximately 16.3%
Answer:
x² = 35
Step-by-step explanation:
This expression as an equation is x² = 35
<em>x</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>second</em><em> </em><em>power</em><em> </em><em>is</em><em> </em><em>x²</em>
<em>Therefore</em><em> </em><em>x</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>second</em><em> </em><em>power</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>35</em><em> </em><em>as</em><em> </em><em>an</em><em> </em><em>equation</em><em> </em><em>is</em><em> </em><em><u>x²</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>35</u></em>
