Answer:

12

Step-by-step explanation:

When the numerators are the same, the denominator that is bigger has a lesser value. In this case, the inequality > shows that \frac{1}{10} is bigger than the fraction next to it so in order to find a fraction that is lesser in value than  \frac{1}{10}, we need to find a denominator that is <u>more than 10</u>, since 10 is the denominator of the first fraction. The only number more than 10 in the options is 12, so 12 is the answer.

What is the standard form of the equation of a line for which the length of the normal segment to the origin is 8 and the normal
jeka57 [31]
Slope of line = tan(120) = -tan(60) = - &radic;3
Distance from origin = 8

Let equation be Ax+By+C=0
then -A/B=-&radic;3, or
B=A/&radic;3.
Equation becomes
Ax+(A/&radic;3)y+C=0

Knowing that line is 8 units from origin, apply distance formula
8=abs((Ax+(A/&radic;3)y+C)/sqrt(A^2+(A/&radic;3)^2))
Substitute coordinates of origin (x,y)=(0,0)  =>
8=abs(C/sqrt(A^2+A^2/3))
Let A=1 (or any other arbitrary finite value)
solve for positive solution of C
8=C/&radic;(4/3) => C=8*2/&radic;3 = (16/3)&radic;3

Therefore one solution is
x+(1/&radic;3)+(16/3)&radic;3=0
or equivalently
&radic;3 x + y + 16 = 0

Check:
slope = -1/&radic;3  .....ok
distance from origin
= (&radic;3 * 0 + 0 + 16)/(sqrt(&radic;3)^2+1^2)
=16/2
=8  ok.

Similarly C=-16 will satisfy the given conditions.

Answer  The required equations are
&radic;3 x + y = &pm; 16 
in standard form.

You can conveniently convert to point-slope form if you wish.

Tell whether the given value is a solution of the inequality.<br><br> a/6 &gt; -4; a = -18
balandron [24]

First we simplify the inequality

1. <em>multiply 6 by the other side of the inequality (-4) </em>

Now we have ...

a > -24

Anything that can be a solution to the inequality <u>must be greater than -24</u>

-18 is greater than -24

This means that, YES! a = -18 IS a solution to the inequality

during the sale, the price of the bicycle was marked down 24 percent. The sale price of the bike was $364. What was the original
kherson [118]
If the price is marked down 24%, that means it is 100-24 = 76% of the original. So we know that $364 is 76% of the original price. x * 0.76 = 364, x = 364/0.76 = $478.95. Make sense?
