True or false 120% of a whole number is always greater than the number? and why?

Stells [14]

I can only use math to explain it. What is 100%?
100% = $\frac{100}{100}$
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = $\frac{120}{100} * 10$ = 12
is it greater than 10.

Write the equation of the line with a slope of 24 and a y-intercept of -5

zmey [24]

Answer:

$y=24x-5$

Step-by-step explanation:

General slope intercept form equation of straight line is given as

$y=mx+b$

where m is slope and b is y-intercept

here m=24 and b=-5

Therefore

$y=mx+b=24x-5$

I need help with this question i dont understand it

RUDIKE [14]

The perimeter, by definition, is the outside measure of that figure. MN and LM are the same length and LK and NK are the same length....we just need to find the lengths! Use the distance formula to find the distance between the 2 points:
$\sqrt{( x_{2} - x_{1} ) ^{2} +( y_{2}- y_{1} ) ^{2} }$
For the segment MN, use the coordinates of M as your x1, y1, and use the coordinates of N for x2, y2:
$\sqrt{(3-2) ^{2}+(4-3) ^{2} }$
which simplifies to
$\sqrt{(1 )^{2}+(1) ^{2} }$ which is $\sqrt{2}$
So that is the length of both MN and LM. So far our perimeter is $\sqrt{2} + \sqrt{2}=2 \sqrt{2}$
Now let's use the same formula to find out the length of one of the longer segments:
$\sqrt{(5-3) ^{2} +(3-2) ^{2} }$
which simplifies down to
$\sqrt{(2) ^{2} +(1) ^{2} }$
which is of course $\sqrt{5}$
Since we have 2 of those lengths, $\sqrt{5} + \sqrt{5}=2 \sqrt{5}$
So our perimeter is, in the end, $2 \sqrt{2}+2 \sqrt{5}$
That's the third choice down
