wolverine [178]

Answer:

1100 cookies

Step-by-step explanation:

There are 3 types of cookies, the first represents 45% of the total, the second 25% and the last type there are 330. We can pose the following equation:

0.45 * x + 0.25 * x + 330 = x

solving for x:

x - 0.45 * x - 0.25 * x = 330

0.30 * x = 330

x = 330 / 0.3

x = 1100

which means that there are a total of 1100 cookies

Light shines through window what is the area of a trapezoid shaped region created by the light
bogdanovich [222]

Answer:

16 ft²

Step-by-step explanation:

The complete question is attached.

A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.

The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.

Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:

The area of a trapezoid = [(3 + 5)/2] * 4

The area of a trapezoid = 16 ft²

If BE bisects _ABD and mŁABE = 28°, find m_ABD.
slamgirl [31]

Answer:

m<ABD = 56 degrees

Step-by-step explanation:

If a segment/ray/line bisects an angle, it divides it into 2 equal parts

Since BE bisects ABD, it will divide it into 2 equal parts, one of which is 28 degrees (given)

Now we can find the measure of ABD by doing 28*2=56
