25 × x = 45

or 25÷100 × x= 45

25 × x = 45

or 25÷100 × x= 45

multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25

therefore, x = 180

( if you use a calculator simply enter 45×100÷ 25)

Assume that y varies inversely with x. If y=1/3 when x=1/2, find y when x=1/4.

LenKa [72]

Answer:

y = $\frac{2}{3}$

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = $\frac{1}{3}$ when x = $\frac{1}{2}$ , thus

$\frac{1}{3}$ = $\frac{k}{\frac{1}{2} }$ = 2k ( divide both sides by 2 )

k = $\frac{1}{6}$

y = $\frac{1}{6x}$ ← equation of variation

When x = $\frac{1}{4}$ , then

y = $\frac{1}{6(\frac{1}{4}) }$ = $\frac{1}{\frac{3}{2} }$ = $\frac{2}{3}$

I have a right angle showing 1/6 how do I figure out what the rest of it equates to

alexgriva [62]

I would think of it as this but i could be wrong.
A right angle is 90 degrees and if you put 1/6 into a decimal it would be 6.
90-6=84
so 84 degrees is missing of the right angle.

330 page/(3/4 Hour):==> 330 : 3/4
To solve this division you have to MULTIPLY the 1st term by the reciprocal of the 2nd (the reciprocal of 3/4 is 4/3), so

330 x 4/3 = (330x4)/3 = 440
330 pages were read in 3/4 Hour (given) & in 1 hour. could be read

HELPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

zvonat [6]

Let's take this step-by-step:

Part (a)

The mathematical name of this shape is a right trapezoid

⇒ It is a trapezoid since the image shows a quadrilateral that

has two parallel sides and two non-parallel sides. It is a right

trapezoid because it has two rights angles

Part (b)

The cube has 6 faces

⇒ faces are the individual flat surfaces of an object

⇒by looking at a picture of a cube, we see it has 6 sides

⇒ (I attached an image of a cube below)

Hope that helps!
