What is the measure of the angle between the hour hand and the minute hand when it is 7:00 and 2:00
sergij07 [2.7K]

Answer:

150 degrees or 210 degrees

Step-by-step explanation:

A circle is equal to 360 degrees. The face of a clock is a circle and therefore 360 degrees. A clock is separated into 12 sections. Divide 360/ 12 = 30 degrees. This means each section is 30 degrees.

Between 2:00 and 7:00 clockwise, there are 5 sections. Since each section is 30 degrees, then 5*30 = 150 degrees.

Between 2:00 and 7:00 counter clockwise, there are 7 sections. Since each section is 30 degrees, then 7*30 = 210 degrees.

The angle depends on the direction of it.

How much smaller is the sum of the first 1000 natural numbers than the sum of the first 1001 natural numbers?
aleksandr82 [10.1K]

ANSWER

1001

EXPLANATION

The sum of the first n - natural numbers is

S_n=  \frac{n}{2} (2a + d(n - 1))

The sum of the first 1000 terms is

S_{1000}=  \frac{1000}{2} (2(1) + 1(1000 - 1))

S_{1000}=500 (1001)

S_{1000}=500500

The sum of the first 1001 terms is

S_{1001}=  \frac{1001}{2} (2(1) + 1(1001 - 1))

S_{1001}= 1001 \times (501)

= 501501

The difference is

501501 - 500500= 1001
