If y=6 when x=2 over 3 find x when y=12

Mathematics
1 answer:
AlexFokin [52]2 years ago
6 0

Answer:

4/3 or 1 1/3

Step-by-step explanation:

So if y = 6, when x = 2/3. Then, x would equal 1 and 1/3, because 12 is twice the amount of 6, so you'd also multiply 2/3 by 2.

(To multiply a whole number by a fraction, first multiply the whole number by the numerator and then divide that by the denominator. For example: 2 × 2 = 4, since you can't really divide 4 by 3 it would stay as is, but you can turn it to a mixed number. 4/3 is the same as 1 whole and an extra 1/3, or in other words 1 1/3).

Hope this helped :)

Michael works 30 hours per week and makes $15.00 per hour. How much does he make in a 4-week month?
Wewaii [24]

Answer:

$1,800

Step-by-step explanation:

If Michael works 30 hours a week for $15 an hour we can use the equation:

15 x 30 = 450.

Now just multiply the given answer by 4 and you're left with:

450 x 4 = 1800.

The table shows the ratio of caramel corn to cheddar cornvin a bag. What is the constant propotionality?
zvonat [6]
Since we know is a proportionality, namely a multiplier on "x", we can simply use any of those points, say hmmm let's use 10, 15,

\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad  y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------\\\\
\textit{we know that }
\begin{cases}
x=10\\
y=15
\end{cases}\implies 15=k10\implies \cfrac{15}{10}=k\implies \cfrac{3}{2}=k

Match each as either linear or non-linear. HELP​
Virty [35]

Answer:

<u>Linear</u>

y=-x

y  =  \frac{x}{9}

-  \frac{2}{3}x + 3y = 1

<u>Non linear</u>

y =  \frac{4}{x}

\frac{2}{y}  = x

{x}^{2}  +  {y}^{2}  = 1

Step-by-step explanation:

Linear equations have the highest degree to be 1.

Therefore y=-x is linear.

y =  \frac{x}{9}  \: is \: also \: linear.

y =  \frac{4}{x}  \implies \: xy = 4

The degree of this equation is 2.

It is non-linear

-  \frac{2}{3}x + 3y = 1

is also linear.

\frac{2}{y}  = x \implies \: xy = 2....non - linear

{x}^{2}  +  {y}^{2}  = 1.....non - linear

What is the length of BC ? Round to the nearest tenth.<br> 16 cm
serg [7]

Since Sin is equal to opposite over hypotenuse

so that's mean Sin(60°) = \frac{x}{16}

#I just rounddown from angle 65° to 60° as the number is not that much different.

and Sin(60°) is equal to \frac{\sqrt{3} }{2}

so we got Sin(60°) = \frac{\sqrt{3} }{2} = \frac{x}{16}

x = \frac{16\sqrt{3} }{2}

x ≈ 14

then we can answer C)14.5

the answer D) is not correct for sure because the opposite cannot be longer than hypotenuse in the Right Triangle form.
