What is the area of the sector that is NOT shaded?A)12π units2
B)24π units2
C)120π units2
D)144π units2

Answer 1

Answer: Hey there! And welcome to Brainly.

Remember that the area of a circle is π*radius^2
Remember that there are 360° in a circle.

The angle of the unshaded part would be 360° minus the shaded part of 60°.
360°- 60° = 300°
Since the area of a circle is πr^2, and the section of the circle is 300°, or 300/360 = 5/6 or one full circle, the area of the unshaded region is
(5/6)π*radius^2
= (5/6)π*12^2
= 120π units^2

Ise the diagram at the right to find the acute angle measure of the hands of a clock at the time 2:20

Answers

The question is about clock hands. The acute angle measure of the hands of a clock at the time 2:20 is 80 degrees.

Clock hands are essential components of analog clocks and watches, indicating the time by their positions. Typically, a clock has three hands: the hour hand, the minute hand, and the second hand. The hour hand is shorter and denotes the hours, while the longer minute hand points to the minutes. The second hand, the thinnest and longest, measures seconds. Clock hands move in a clockwise direction, and their synchronized motion helps people tell time at a glance, making them fundamental features of timekeeping devices for centuries.

To find the acute angle measure of the hands of a clock at the time 2:20, we need to determine the angle covered by the hour hand. In going from 12 to 3, the hour hand covers 1/4 of the 12 hours needed to make a complete revolution. Therefore, the angle between the hour hand at 12 and at 3 is 90 degrees. Since it is 20 minutes past 2, the minute hand will be 1/3 of the way between 2 and 3. This means the minute hand will be at an angle of 1/3 x 30 degrees = 10 degrees. The acute angle between the hour and minute hands can be found by subtracting the smaller angle from the larger angle. So, the acute angle measure of the hands of the clock at the time 2:20 is 90 degrees - 10 degrees = 80 degrees.

Answer:

50 degrees

Step-by-step explanation:

To find the acute angle measure between the hour and minute hands of a clock at 2:20, you can use the following method:

First, calculate the minute hand's position:

The minute hand moves 360 degrees in 60 minutes, so in 20 minutes, it covers (20/60) * 360 = 120 degrees.

Next, calculate the hour hand's position:

The hour hand moves 360 degrees in 12 hours, so in 2 hours and 20 minutes, it covers (2 + 20/60) * (360/12) = (2 + 1/3) * 30 = (7/3) * 30 = 70 degrees.

Now, find the acute angle between the hour and minute hands:

Subtract the hour hand position from the minute hand position:

120 degrees (minute hand) - 70 degrees (hour hand) = 50 degrees.

So, the acute angle measure between the hands of the clock at 2:20 is 50 degrees.

Nell's mortgage is $50,150 at 10 percent for 30 years. What is her monthly payment if she must pay $8.78 points per $1,000?a) $440.32
b) $439
c) $442.95
d) $385.89

Answers

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

EMI on $1000 is $8.78, so EMI on $1 is

$\text{EMI on }\$1=(8.78)/(1000)=0.00878$

EMI on $50150 is

$\text{EMI on }\$50150=0.00878* 50150=440.317\approx 440.32$

Therefore the correct option is a.

The right answer for the question that is being asked and shown above is that: "d) $385.89." Nell's mortgage is $50,150 at 10 percent for 30 years. Her monthly payment if she must pay $8.78 points per $1,000 is that of d) $385.89

What is the formula for finding a1 in the geometric series sn=48455, r=3.2, n=3?

Answers

The formula for finding the sum in the geometric series: $S_(n)=a_(1) * ( r^(n) -1)/(r-1)$ For finding a1: $a_(1) = ( S_(3)*(3.2-1) )/( 3.2^(3)-1 ) = (48455*2.2)/(32.768-1)= (106601)/(31.768)=3355.6094$
