Answer:

75/7 degrees or 10 and 5/7

Step-by-step explanation:

Complementary angles add up to 90 degrees. So, (6x-47) + (x+4) = 90

Combine like terms

7x-43=90

Subtract 43 from both sides

7x=47

x = 6 and 5/7

Plug this into the equation for the measure of angle s

6 and 5/7 + 4 = 10 and 5/7

For whole numbers between 1 and 1001, inclusive, let m be the sum of odd numbers and n be the sum of even numbers. What is the v

Svetradugi [14.3K]

Answer:

m - n = 501

Step-by-step explanation:

Remark

The first thing you have to do is find the number of odd and even numbers. This is where you have to be careful because there is a danger of being out by one.

equation

l = a + (n - 1)*d

Solution even

l = 1000

a = 2

d = 2

1000 = 2 + (n - 1)*2

998/2 = (n - 1) * 2 / 2

499 = n - 1

n = 500

Solution odd

l = 1001

a = 1

d = 2

1001 = 1 + (n - 1)*2

1000 = (n - 1)*2

1000/2 = (n - 1)2/2

500 = n - 1

501 = n

Sum Even of even numbers from 1 to 1001

Givens

a = 2

n = 500

l = 1000

Equation

Sum = (a + l ) * n / 2

Solution

Sum = (2 + 1000)*500/2

Sum = 1002 * 250

Sum = 250500

Sum of Odd numbers from 1 to 1001

a = 1

l = 1001

n = 501

Equation

sum = (a + l)*n/2

sum = (1 + 1001) * 501

sum = (1002)*501 / 2

Sum = 251001

Answer

m - n = 251001 - 250500 = 501

If you bought a stock last year for a price of $36, and it has gone down 16.6% since then, how much is the stock worth now, to t

Pepsi [2]

Answer:

The stock is now worth of $30.024.

Step-by-step explanation:

Here, the price of the stock last year =$36

The percentage down in the price of stock in a year = 16.6 %

Now, 16.6% of the value of stock $36 = $\frac{16.6}{100} \times 36= 5.976$

⇒16.6% of $36 = $ 5.976

Now, the Current Worth of Stock = Stock Value last year - Decrease in the stock price

= $36 - $ 5.976 = $30.024

Hence, the stock is now worth of $30.024.
