What is the sum of the first 39 positive odd numbers?

liq [111]

1-39 ODD:
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39
Now you'd add them all up.
1+3+5+7+9 = 25
11+13+15+17+19 = 75
21+23+25+27+29 = 125
31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.

In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 270 degrees.

aliya0001 [1]

Answer: 28.26 ft

Step-by-step explanation:

The formula to calculate the length of arc $l$ is:

$l=r \theta$

Where:

$r=6 ft$ is the radius of the circle

$\theta=270\° \frac{\pi}{180\°}=\frac{3}{2} \pi=4.71 rad$ is the angle in radians

$l=(6 ft)(4.71 rad)$

$l=28.26 ft$ This is the length of the arc

What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?

photoshop1234 [79]

Answer:

value of n = 2

Step-by-step explanation:

$\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}$

We need to solve the above equation.

Find Least Common multiplier from 5n, 5 = 5n

Multiply both sides of the equation by 5n

$\frac{4}{5n}*5n-\frac{1}{5}*5n=\frac{2}{5n}*5n\\Solving:\\4 -n = 2\\$

Now finding the value of n.

Adding -4 on both sides

$4 -n-4 = 2-4\\-n= -2$

Multiplying both sides by -1

n = 2

The value of n is 2.

We can verify by putting value of n in the given question.

$\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}\\n=2\\\frac{4}{5*2}-\frac{1}{5}=\frac{2}{5*2}\\\frac{4}{10}-\frac{1}{5}=\frac{2}{10}\\\frac{2}{5}-\frac{1}{5}=\frac{1}{5}\\\frac{2-1}{5}=\frac{1}{5}\\\frac{1}{5}=\frac{1}{5}$

So, value of n = 2
