what is the formula to find perimeter​

Answer: 14/-27

Step-by-step explanation:

4/9 divided by -6/7 = 4/9 times 7/-6

4/9 times 7/-6 = 2/9 times 7/-3 = 14/-27

Answer:

the answer is The second one

Step-by-step explanation:

You basically have to divide your number from a prime factor until your result is 1

For example

12

you divide it from the lowest prime number possible, for in this case, 2

12/2 = 6 and you can set aside 2 for now

You do the same thing and you divide it by 2

6/2 = 3 and set aside 2

Now 3 isn't divisible by 2 so you'll find another number, for in this case 3

3/3 = 1

your set side numbers are now 2,2,3

so you'll find out 12 = 2x2x3 as a product of it's prime factors

how ever you cant divide it by 4 or 6 since they aren't prime factors as they are divisible by other numbers

My calculator shows that

(2.1)/(1.488) = 1.41129

which is approximate. If you want the result to two decimal places, then it would be 1.41 and not 1.40

Try 1.41 and it should work out, assuming your teacher wants two decimal places.

Answer:

[tex] \frac{2}{5} [/tex]

Step-by-step explanation:

[tex] \frac{11}{15} - \frac{1}{3} \\ \frac{11}{15} - \frac{1 \times 5}{3 \times 5} \\ \frac{11}{15} - \frac{5}{15} \\ \frac{6}{15} \\ \frac{6 \div 3}{15 \div 3} \\ \frac{2}{5} [/tex]

11/15 - 1/3 is 2/5.

Given that we need to simplify 11/15 - 1/3.

So,

There must be a common denominator in order to subtract fractions. Since both 3 and 15 can be divided into it in this instance, the common denominator is 15.

If you multiply the numerator and denominator of 1/3 by 5/5 to get a denominator of 15, you can write 11/15 - 1/3 as (11/15) - (5/15).

You can now take the numerators away:

(11/15) - (5/15) = (11 - 5)/15 = 6/15

By dividing the numerator and denominator by their largest common factor, which is 3, the fraction 6/15 can be made even simpler:

6/15 ÷ 3/3 = 2/5

Therefore, 11/15 - 1/3 is 2/5.

Answer:

The correct choice is option C. -7/5 + 11/5i

Step-by-step explanation:

  3 + 5i / 1 - 2i

= (3 × 1 + 5 (-2)) + (5 × 1 - 3(-2)) / 1^2 + (-2)^2

= -7 + 11i / 5

= -7/5 + 11/5i

Answer:

option C. -7/5 + 11/5i

Answer:

Step-by-step explanation:

a) 64 (A=bh)

b) 96 ((16x12)÷2)

Answer:

Step-by-step explanation:

a) base = AB = 16 cm

height = DX = 6cm

Area of  the parallelogram = base * corresponding height to the base

                                            = 16 * 6

                                            = 96 sq. cm

Area of parallelogram =  96 sq .cm

BC * DY = 96

12 * DY = 96

      DY = 96/12

      DY = 8 cm

Answer:

687/999

Step-by-step explanation:

Let x=0.687687....

Then 1000x=687.687687...

                x=     0.687687

Subtract x from 1000x

999x = 687

So

x = 687/999

Answer:

Ratio should be equal so ratio is 3:3

The ratio of the triangles to circles in the diagram below would be; 1: 1

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained.

Thus, there are three circles and three triangles shown in the figure.

Therefore, the ratio will be;

three circles: three triangle

3 : 3

1: 1

Hence, the ratio of the triangles to circles in the diagram below would be; 1: 1

Hi :)

The volume of a sphere is

V = 4/3 (pi) r^3

Supposing "length" as diameter

We can take the radius

2.40/2

1.2 is the radius of the sphere.

Inserting the radius into the formula

V = 4/3 (pi) 1.2^3

The volume is aproximately 7.24cm^3

hi <3

1) as the value ahead of the tenths position is a 5, you would round up.

this gives you the answer of 1.6

2) as the value ahead of the hundredths position is a 4, you would round down.

this gives you the answer of 1.55

3) as the value ahead of the thousandths position is an eight, you would round up.

this gives you the answer of 1.555

hope this helps :)

So first you could need to find the x and y intercepts.

So the x intercept can be found why y is zero and vice versa.

so your graph would go through the points (0,5) and (2.5,0)

When expressions are equivalent, the expressions have the same value. The number x is 42, because 10 less than 42 is 32.

The number is represented as x

10 less than x is represented as x - 10

From the question, we understand that the 10 less than x is equivalent to 32.

So, the expression becomes

[tex]x - 10 =32[/tex]

Collect like terms

[tex]x = 32 + 10[/tex]

Add 32 and 10

[tex]x = 42[/tex]

Hence, the number (x) is 42
