True. it can only be written as one repeating number because eventually, a set of numbers would cancel out i think

Find the exact value of s in the given interval that has the given circular function value.

docker41 [41]

Answer:

$\displaystyle s=\frac{3\pi}{4}$

Step-by-step explanation:

Trigonometric Values

We need to find the angle s in the interval [π/2,π] where:

$\displaystyle \sin s=\frac{\sqrt{2}}{2}$

There are two possible angles that have the same sine value in the first rotation of s. Any angle on the first quadrant has the same sine as its supplementary angle in the second quadrant.

The first angle s whose sine is $\frac{\sqrt{2}}{2}$ is:

$\displaystyle s=\frac{\pi }{4}$

The other angle is its supplementary angle:

$\displaystyle s=\pi-\frac{\pi }{4}=\frac{3\pi}{4}$

Only this last angle lies on the required interval, thus:

$\boxed{\displaystyle s=\frac{3\pi}{4}}$

Solve for x, -4/5x -3/20 x + 1/4x = -70

Ira Lisetskai [31]

Answer:

x=100

Step-by-step explanation:

Simplify -4/5x-3/20x+1/4x

-7x/10=-70

Multiply both sides of the equation by -10/7.

-10/7*(-7x/10)=-10/7*-70

Simplify both of the equation.

x=100

Jasmine reduced the size of a triangle to a height of 4 in. What is the new width if it was originally 12 in wide and 16 in tall

cupoosta [38]

Answer:

The new width is 3 in.

Step-by-step explanation:

We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.

12 = x

16 4

Then solve for x:

x = 4 (12/16)

x = 3

To check:

12/16 = 3/4

3/4 = 3/4
