The minute hand of a clock is 7 inches long how far does the point of the hand travel in one hour

Answers

Answer 1

Answer: The hand represents the radius of the circle of the clock, so we would want to find the perimeter of the circle to begin with to determine how far the point of the hand would travel full circle (12 hours) To do this we would use the equation 2(pi*radius) we would use 3.14 as pi in this equation.

p=2(3.14*7) solves to 43.98 inches. This means the point of the hand travels 48.98 inches in 12 hours, to find how far it moves in just one hour, we would divide 43.98 by 12. This gives us the final answer of 3.665 inches traveled in one hour.

Explain how to find 40 times 80 using mental math

Answers

Using mental math's, the product of 40 times 80 is: 120

How to find the product of numbers?

We want to find the number product given as:

40 times 80

Now, this can be expressed as:

40 * 80

This means a product or multiplication of 40 and 80.

We can break the numbers down as:

40 = 4 * 10

80 = 8 * 10

Thus, we have:

(4 * 10) + (8 * 10)

= 10(4 + 8)

= 10 * 12

= 120

First you can use simple multiplication. Take out the zeroes from 40 and 80. You get 4 and 8. 4 multipled by 8 is 32. so that means that 80 times 40 is 320

RS has endpoints R(-2,3) and S(-8,-2) whats the midpoints? whats the quadrants?

Answers

R is in Quadrant II and S in Quadrant III.

The midpoint in the x-direction is (-2-8)/2, or -5.

The midpoint in the y-direction is (3-2)/2, or 1/2.

The (single) midpoint is (-5,1/2).

Lines b and c are parallel. What is the measure of 2? m2 = 31° m2 = 50° m2 = 120° m2 = 130°

Answers

Answer:

m2 = 50

Step-by-step explanation:

7x+1+18x+4=180

25x+5=180

25x=175

x=7

m2= 7(7)+1 = 50

Answer:

2. $m\angle 2=50^(o)$

Step-by-step explanation:

We have been given that lines b and c are parallel.

Since we know that vertical angles are always congruent. We can see that measure of angle 2 will be equal to $(7x+1)^(o)$ as it is the measure of vertical angle of angle 2.
