Anyone know the answer?
Zepler [3.9K]
If you look from the points at angle 73, to 42, to 131, to z,  the shape makes a quadrilateral.
Since the total of the interior angles in a quadrilateral add up to 360 you make an equation:

360 = 131 + 73 + 42 + 7 + x
Re-arrange the equation to get the x alone, by subtracting:
360 - 131 - 73 - 42 = x
114 = x

So x = 114 degrees<span />

How man 1/3 cups make 3/4 cups
Sati [7]

Answer:

it would take 2.25 1/3 cups if you are looking for an exact answer, or if you are looking for the minimum amount of 1/3 cups necessary to make 3/4 it would be 3.

Step-by-step explanation:

You can solve this by cross multiplying 1/3 and 3/4

You will get 9/4 which simplifies to 2 1/4 or 2.25

The pendulum swings at an arc of 30 cm and its successive swings reduced to 10% of the previous swings. What is the total distan
OleMash [197]

Answer:

S_g=  33.333cm

Step-by-step explanation:

From the question we are told that

Arc of 30 cm

10% reduction after each swing

Generally sum of geometric sequence is given by the equation

    S_g=\frac{a(1-r^n)}{1-r}

Mathematically solving for total distance traveled we have

    S_g=\frac{30(1-(0.10^5)}{1-(0.10)}

    S_g=\frac{30}{0.9}

Therefore the total distance traveled  by the pendulum after 5 swings

    S_g=  33.333cm

If a person takes a jump which is half a feet and then gets tired so he takes another jump which is half if the first jump and h
patriot [66]
He will never reach the full foot, this is because if he travels 1/2 of the distance of the previous jump each time there will always be a fraction that is unaccounted for.

Is 15/28 equivalent to 25/45
Lana71 [14]
No, it's not.

15/28 equals to (about) 0.54 while 25/45 is (about) 0.56.
They are close, but not equivalent.<span />
