Determine the 20th term of the sequence 1,4,7,...

2 answers:

6 0

It is 58
That's the 20th number in the sequence since each term is 3 more than the last number. An easy way to do this is multiply 19 times 3 because there are 19 terms after one. Then multiply by 3 because each term is 3 more than the last term. After you do 19 x 3 you get 57 right? Then add 57 to 1, the first term, to get 58.

Each term goes up by 3 so if n is the nth term and y is the value y=3n but the first term is 1 not 3 so
y=3n-2
The 20th term is n=20 so
y= 58

4/6 x what equals 8/6

Sidana [21]

Answer: 4/6

1. Subtract 8/6 by 4/6.

8/6 - 4/6 = 4/6

4/6 + 4/6 = 8 is the same as:

4 + 4 = 8

Notice: You don't change the denominator if your adding or subtracting.

That's why 4 + 4 = 8 is the same as 4/6 + 4/6.

<h2>Final answer: 4/6. </h2>

in a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b what is

puteri [66]

Answer:

Step-by-step explanation:

a=12 (height)

c=13 (hypotenous)

b=? (base)

By using Pythagoras theorm

We have, hypotenous sq=base sq+height sq

Let b =base SO, base sq=hypotenous Sq-height Sq

=>base Sq =13sq-12sq

Base Sq =169-144

Base Sq =25

Base =5 (shifting the sq)....

Convert 150 degrees to radian

Dafna1 [17]

Answer:

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × $\frac{\pi }{180}$

Hence

radian measure = 150° × $\frac{\pi }{180}$

Cancel both 150 and 180 by 30, then

radian measure = 5 × $\frac{\pi }{6}$ = $\frac{5\pi }{6}$
