Given:  

total cookies John bought= 15 cookies,

Number of cookies john ate = 3 cookies

To Find:

Percentage of cookies John ate. =?

Solution:

We know that the formula of finding the percentage of any thing which is given as

percentage=\frac{(given value)}{(total value)}\times100

So according to question,  we have given value = 3

And Total value = 15

Now we will put these values in the formula of percentage to find out the % of cookies that he ate.

percentage=\frac{3}{15}\times100=20\%

Hence , he ate 20% of cookies

In a right triangle, what is the 3rd angle measure if an angle is 25
melomori [17]

Answer:

If the quadratic functions for the equations are graphed, which is the widest?
alexandr402 [8]

Answer:

  D)  y = 1/4 x^2

Step-by-step explanation:

For these functions, the leading coefficient can be considered to be either ...

  the vertical scale factor (larger ⇒ narrower)

  the square of the inverse of the horizontal scale factor.

In the latter case, the horizontal scale factor will be larger (wider) when its inverse and the square of its inverse are smaller.

Either way, you're looking for the smallest leading coefficient: 1/4.

Given that parallelogram ABCD and angle D=145 what is the measure of angle C
stiv31 [10]
Opposite angles of parallelogram are equal.
sum of interior angles of parallelogram is 360 degrees.

Therefore,
A + B + C + D = 360
x + 145 + x + 145 = 360 
x = 35
Therefore angle C is 35 degrees
