Solve for x <br><br> (5x-1) 8x
trapecia [35]

Answer:

x = 7

Step-by-step explanation:

Given is the figure of a kite.

Opposite sides are equal... (given)

Since, measures of the angles opposite to equal sides are equal.

Also, diagonals of a kite interests at right angles.

Therefore,

8x \degree + (5x - 1) \degree + 90 \degree = 180 \degree \\  \\  (8x + 5x - 1) \degree   = 180 \degree -  90 \degree\\  \\(13x - 1) \degree   = 90 \degree\\  \\ 13x - 1 = 90 \\  \\ 13x = 90 + 1 \\  \\ 13x = 91 \\  \\ x =  \frac{91}{13}  \\  \\ x = 7

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
