PLEASE SHOW WORK

Answers

Answer:

x = √30 or -√30

Step-by-step explanation:

480 - 16x^2 = 0

divide both sides by 16

30 - x^2 = 0

-x^2 + 30 = 0

-x^2 = -30

X^2 = 30

x = ± √30

x = √30 or -√30

How many blue circles are equivalent to the orange square? Explain how you know.​

Answers

Answer:

5 blue circles are equivalent to the orange square

Step-by-step explanation:

If you take away 2 blue circles from each side so that the orange square is by it's self, and the equation stays balanced, you will be left with 5 blue circles on the side without the orange square.

Answer:

5

Step-by-step explanation:

There are a total of 7 blue circles on the right side and 2 on the left.

You also know that both sides are equivalent.

You can assume that the all the blue circles have the same weight

If you subtract the only blue circles from the left from the 7 blue circles on the right you get

1 orange square on the left and 5 blue circles on the right.

1 over 3 , 3 over 4 ,4 over 7 , 7 over 11, 11over 8 .... (i)one termof this sequence is p over q . Find the term of p and q , the next term in this sequence . Find the 6th term of this sequence 1).... 2).....

Answers

Answer:

Next term will be the 6th term i.e. a₆ will be:

a₆ = 14/11

Here:

p = numerator = 14q = denominator = 11

Step-by-step explanation:

Given the sequence

[tex]\frac{1}{3},\:\frac{3}{4},\:\frac{4}{7},\:\frac{7}{11},\:\frac{11}{8},...[/tex]

First of all the terms of the sequence are in p/q form, where p is the numerator and q is the denominator.

As the fifth term of the sequence is:

a₅ = 11/8

From the given sequence it is clear that the numerator is changing by 3 units and the denominator is also changing by 3 units.

Thus,

The next term will be the 6th term i.e. a₆ will be:

a₆ = 14/11

Here:

p = numerator = 14q = denominator = 11
