Part1

there are 360° in a circle (clock), and thus if we check how many degrees in a clock with 60minutes, then it'd be 360/60, or 6° per minute

now, the clock went from 3:35 to 3:55, 20 minutes, how many degree is that? 6*20

The shaded region is the area of the circle minus the area

of the pentagon.

A circle = pi * r^2

A circle = pi * 15^2

A circle = 706.5 cm^2

A regular pentagon = (a * p)/2 where a is the apothem, p is the perimeter.

The apothem id the perpendicular height from the midpoint of a side to the center of the pentagon.

To find the apothem you have to use a trig ratio.

A pent = (8.3 * 12*5)/2

A pent = 249 cm^2

Shaded region: circle - pentagon 706.5 - 249 = 457.5

of the pentagon.

A circle = pi * r^2

A circle = pi * 15^2

A circle = 706.5 cm^2

A regular pentagon = (a * p)/2 where a is the apothem, p is the perimeter.

The apothem id the perpendicular height from the midpoint of a side to the center of the pentagon.

**Answer:**

The midpoints of the EF is (2a,a) .

**Step-by-step explanation:**

Definition of midpoints.

The midpoint is the point lie in middle of a line segment. It is equidistant from both endpoints .

Formula

Quadrilateral EFGH has coordinates E(a, a), F(3a, a), G(2a, 0), and H(0, 0).

Now find out the midpoints of the E(a, a) and F(3a, a) .

Midpoints of EF = (2a,a)

Therefore the midpoints of the EF is (2a,a) .

This is the concept of probability and statistics, we are required to calculate the probability of getting a red, blue and black respectively, given that there are 3 red, 8 blue and 7 black beads;

Probability of an event occurring=(Number of ways it can occur)/(Total number of outcomes )

The total number of outcome in our situation is:

3+8+7=18

P(Red)=3/18=1/6

P(Blue)=8/17

P(Black)=7/16

since these occurrence are such that the selection is without replacement, that means they are dependent. The probability of them occurring in that order will be:

P(x)=1/6*8/17*7/16=7/204

The answer is d. dependent; 7/204

**O = 50°**

- An
**isosceles trapezoid**is a quadrilateral that has a pair of sides that opposite and are parallel and another pair of sides that are opposite and are congruent.

- Both pairs of opposite angles in an isosceles trapezoid are supplementary which means their sum add up to 180°.

**Therefore; **

**∠ B + ∠ A = 180° and ∠T + ∠O = 180°**

**Hence; ∠O = 180 -∠T**

** = 180 - 130°**

** = 50 °**

The scale length is 9cm and the scale is 6cm/15ft which is 3cm/5ft, so we can say:

9cm(5ft/3cm)=15ft for the length

If you wanted the width too...

4cm(5ft/3cm)=20ft/3 (6'8", 6ft 8in)

9cm(5ft/3cm)=15ft for the length

If you wanted the width too...

4cm(5ft/3cm)=20ft/3 (6'8", 6ft 8in)
