Answer:

hello : answer : a) 9 cm 2

Step-by-step explanation:

A square has a perimeter of 12 : p = 4×c.....c is the length

12 = 4c

c = 12/4

c = 3

the area A= c²

A= 3² = 9 cm 2

a. 9 cm 2 because each side would be 3 and length x width would be 3 x 3 = 9

What is the value of m in the equation 1/2m-3/4n when n = 8?

kirill [66]

Answer:

$-\frac{1}{32}$

Step-by-step explanation:

$n = 8\\1/2(8) - 3/4(8) = 1/16-3/32$

Multiply the numerator and denomiator of 1/16 by 2 so that the denominators are equal and we can subtract.

$\frac{1}{16} *\frac{2}{2} =\frac{2}{32}$

Then, subtract

$\frac{2}{32} -\frac{3}{32} = \frac{2-3}{32} =- \frac{1}{32}$

Step-by-step explanation:

Next, let's solve 3x+2y = 10 for the variable y. Move the 3x to the right hand side by subtracting 3x from both sides, like this: 3x - 3x = 0. The answer is 2y. The answer is 10-3x.

Use the formula to evaluate the series 1+2+4+8+...a10

valina [46]

Answer:

The sum of the given series is 1023

Step-by-step explanation:

Geometric series states that a series in which a constant ratio is obtained by multiplying the previous term.

Sum of the geometric series is given by:

$S_n = \frac{a(1-r^n)}{1-r}$

where a is the first term and n is the number of term.

Given the series: $1+2+4+8+.................+a_{10}$

This is a geometric series with common ratio(r) = 2

We have to find the sum of the series for 10th term.

⇒ n = 10 and a = 1

then;

$S_n = \frac{1(1-2^{10})}{1-2} =\frac{1-1024}{-1} =\frac{-1023}{-1}=1023$

Therefore, the sum of the given series is 1023
