Determine whether 2/15 is closest to 0,1/2 or 1

1 answer:

7 0

Since 15ths are smaller pieces 2 of 15 would'nt even really be close to 1/2 half of 15 is 7.5 so not even close. or 1 so the answer would be that it is closer to 0. Hope it helps!!

Answer:

$P(w)=0.2w+1$

Step-by-step explanation:

Let is call $P$ the price of the cereal box, and $w$ its weight, then the linear equation of the price $P(w)$ as a function of weight $w$ will be

$P(w)=mw+b$ ,

where $m$ is the slope of the linear equation, and $b$ is the y-intercept.

We find $m$ by evaluating the rise/ run of the linear equation:

$m= \frac{ \Delta rise}{ \Delta run} = \frac{ \Delta price}{ \Delta weight} =\frac{5-3}{20-10} =\frac{2}{10} \\\\\boxed{m=0.2}$

thus we have

$P(w)+0.2w+b$

now we figure out $b$ from the point ($5, 20 ounces):

$5=0.2(20)+b\\5=4+b\\\\\boxed{b=1}$

So finally we have the function

$\boxed{P(w)+0.2w+1}$

which expresses the price of a box of cereal as a function of the number of ounces of cereal in the box

<h3>What is an isosceles triangle?</h3>

An isosceles triangle is a triangle with base angles equal with any two sides equal.

Analysis:

∠ACB = 120

ABC is isosceles, so ∠CAB = ∠CBA = x

x + x + 120 = 180 ( sum of angles in Δ ABC)

2x = 60

x = 30

∠AMC = 180 - ∠BMC( angles on a straight line)

= 180 - 60 = 120

∠ACM = 180 - (30 + 120) = 180 - 150 = 30°

∠MCB = 90°

using sine rule,

12/sin 30 = AM/ sin 30

AM = 12

MB/sin 90 = 12/sin30

MB sin 30 = 12 sin 90

MB = 12/sin 30 = 12/0.5 = 24

AB = MB + AM = 24 + 12 = 36

Simplify 5s^-7/10s^-9

crimeas [40]

Simply cancel the common factor of 5 to get...
$\frac{s^-7}{2s^-9} \ \textgreater \ Apply exponent rule \ \textgreater \ \frac{x^a}{x^b} = x^{a - b} \ \textgreater \ \frac{s^-7}{s^-9} = s^{-7 - (-9)} = s^2 \ \textgreater \ \frac{s^2}{2}$
Therefore our final answer is.
$\frac{s^2}{2}$
