### Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 3:35 to 3:55? (Hint: Find the number of degrees per minute first.) Part 2: How far does the tip of the minute hand travel during that time?

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

### Can someone help me find the area of the shaded region? is it just the area of the circle?

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

### Quadrilateral EFGH has coordinates E(a, a), F(3a, a), G(2a, 0), and H(0, 0). Find the midpoint of EF? Please show how the problem is done.

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) .

### A bowl contains 3 red, 8 blue, and 7 black beads. Margaret randomly selects 3 beads one after the other without replacement. Find the probability of getting a red, blue, and black bead, in that order. a. dependent; 204/7 b. independent; 7/243 c. independent; 1/68 d. dependent; 7/204

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

X years  -  Sara (now)
3x years  -  Ralph (now)

(x + 6)  -  Sara (in 6 years)
(3x + 6)  -  Ralph (in 6 years)

1) 3x + 6 = (x + 6) * 2
3x + 6 = 2x + 12
3x - 2x = 12 - 6
x = 6 years - Sara (now)
2) 6 * 3 = 18 years - Ralph (now)

In 6 years :
6 + 6 = 12 - Sara
18 + 6 = 24 - Ralph
24 : 12 = 2 - twice as old as Sara/

O = 50°

### Explanation and solution;

• 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 °

### A patient is given a 100-milligram dosage of a drug that decays exponentially at a rate of 11% per hour. Which equation could be used to find the time when 15 milligrams of the drug remain? A. 100 = 15(0.89)^x B. 100 = 15(0.11)^x C. 15 = 100(0.89)^x D. 15 100(0.11)^x

Exponential functions can be expressed as:

f=ir^t, f=final value, i=initial value, r=rate or common ratio, t=term number or "time" when it is fractional...In this case we have:

f=100((100-11)/100)^x

f=100(0.89)^x and we want to solve for when f=15 so

15=100(0.89)^x

Answer:

Option B. 1134.16 cm³

Step-by-step explanation:

The surface area of two similar solids are 1,008 cm² and 1372 cm²

Since surface area is a two dimensional unit or surface area is the multiplication of two dimensions.

Ratio of the sides of the solids will be

Ratio of sides =

= 1.167

Now ratio of volume of the solids will be cube of the sides.

=

By cross multiplication

V(1.167)³ = 1801

V = = 1134.16 cm³

Option B. 1134.16 cm³ is the answer.
