Which is the sum of the first 6 terms of the geometric series? 7+21 +63

Mathematics
1 answer:
Gwar [14]3 years ago
5 0

Answer:

2,548

Step-by-step explanation:

First, we have to find out the rule. The rule is multiply the previous number by 3 to get the next number.

7x3=21

21x3=63

So, we would continue this pattern until we have the first 6 numbers which are 189, 567, and 1701.

The questions is asking for the SUM of the 6 numbers so you would add the those numbers and do this equation:

7+21+63+189+567+1701= 2548

Hope this helps! :)

Tom jogged 3/5 on Monday and 2/6 mile on Tuesday. How much farther did Tom jog on Monday than on Tuesday
natali 33 [55]
You will want to subtract the amount he ran on Monday from the amount on Tuesday. In order to subtract fractions, we must set them to the same denominator (bottom number). In order to do this, we must multiply 3/5 by 6/6 (the denominator on tuesday) which gets us 18/30. Then, for Tuesday, we must multiply 2/6 by 5/5 (the denominator on Monday) which is 10/30. Now, we can do Monday-Tuesday, 18/30-10/30 which gets us 8/30, if we simplify this, we get 4/15 :)

Giving brainliest *easy*
elena-14-01-66 [18.8K]

Step-by-step explanation:

The formula is given by :

s=\dfrac{m}{360}\times 2\pi r

We have,

m = 19° and d = 9 cm

So,

s=\dfrac{19}{360}\times 2\pi \times \dfrac{9}{2}\\\\s=1.49

Hence, this is the required soltion.

Show steps for 5-x÷3=-7
Alla [95]

5-x÷3=-7

Add 3 to both sides of the equation.

5x=3+7

Divide each term by 5 and simplify.

Divide each term in 5x=10 by 5

5x/5=10/5

Reduce the expression by cancelling the common factors.

x= 10/5

Divide 10 by 5

Answer <em>x </em>=2
