Please can you help it says £300
Oksi-84 [34.3K]
This can be done algebraically:

300*x=330 Where x is the multiplier
Therefore x=330/300=1.1

To find a percentage of a number you multiply by the percentage divided by 100.
So 330 is 110% of 300, which is an increase of 10%.

Use the rule to write the first five terms of the pattern.
AlekseyPX

Answer:

A =First term of the pattern = 11

To find the first five terms we have to use the rule which is

Add 10 to first term and then subtract 5 from it.Which is equivalent to

= A +10 -5

1. Second Term = 11 + 10 -5

  = 21 - 5

   =16

→Third term = 16 +10-5

        = 26 - 5

       = 21

→Fourth term : 21 + 10 - 5

     = 31 -5

      = 26

→Fifth term : 26 +10 -5

                = 36- 5

                = 31

→Sixth term:

=31 + 10- 5

= 41 -5

 = 36

So, the first five term apart from 11 is 16, 21,26,31,36 which is an Airthmetic progression.

Find the sum of the counting numbers from 1 to 25 inclusive. In other words, if S = 1 + 2 + 3 + ... + 24 + 25, find the value of
Anastaziya [24]

Answer:

325

Step-by-step explanation:

You must have heard about Arithmetic Progressions (AP)

Arithmetic progressions are a series of numbers such that every successive number is the sum of a constant number and the previous number.

Our very own counting numbers form AP

For example :-

2 = 1 + <u>1</u>

3 = 2 + <u>1</u>

4 = 3 + <u>1</u>

The number in bold (1) is that constant number which is added to a number to form its successive number.

To find the sum of series forming AP, we use the formula :-

sum =  \frac{n}{2} \{ a  + a  _{n}  \}

here,

  • n is the number of terms
  • a is the first number of the series
  • an is the last number of the series

So we'll use all this information to find the sum of continuous numbers from 1 to 25 where 1 is the first term(a) and 25 is the last(an).

and n is 25

S  =   \frac{25}{2}\{ 1  +25\}

=  \frac{25 \times 26}{2}

= 25  \times 13

= 325

So, the value of S comes out to be 325.

When using inverse operations, what should you do to solve y - 7 = 10?
tatyana61 [14]

Answer:

17

Step-by-step explanation:

There is a SUBTRACTION symbol in the problem. So, you will do the opposite, & ADD the 2 available numbers in the equation. 10+7=17

When you replace that y with 17, the equation is correct.
