First find the constant k. For inverse variation, k=yx.
k=(8/3)*3=8
8=yx or y=8/x
8=4y
y=2
Hope this helps.

Use long division to determine the decimal equivalent of fraction with numerator 2 and denominator 3. 0 point 6 bar 0 point 7 ba
VikaD [51]

Answer:

The correct answer is A

0.\bar6

Step-by-step explanation:

We want to determine the decimal equivalence of \frac{2}{3}.


We perform the long division as shown in the attachment.


Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is 2, will be inside the long division sign.

We see that the quotient of our long division is 0.6666....


We can rewrite this as 0.\bar6


Therefore \frac{2}{3}=0.\bar6.

julia-pushkina [17]

Answer:

1285.37

Step-by-step explanation: You can use the formula for compound interest:  

P(1+R)^t

P = the principle, the amount of money

(1+R) = the rate, (%) as a decimal plus 1

^t = to the power of the number of years

Substitute the values:

750(1+0.08)^7

750(1.08)^7

The ratio of the measures of the angles in a triangle is 2:9:4 what is the measure of the largest angle ?
FrozenT [24]
You need to add all of these values together. This is 2 + 9 + 4 which gives 15

There are 180° in a triangle. Divide this by 15.

180/15 = 12

Then multiply this by the largest in the ratio; which is 9.

This is 12 x 9 which = 108°.

The largest angle is therefore 108°.

For reference, the ratio in degrees would look like this:

24:108:48, which adds up to 180°.
