Answer:

27

Step-by-step explanation:

Given the expression

[tex]\left(3^{-6}\times 3^{3}\right)^{-1}\\[/tex]

According to law of indices, this can be written as;

[tex]\left(3^{-6+3})^{-1}\\\\= (3^{-3})^{-1}\\\\= 3^{-3*-1}\\\\= 3^3\\\\= 27[/tex]

Hence the required answer is 27

Answer:

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

The formula for dividing fractions.

= a/b ÷ c/d

= ad/bc

The number of subjects studied for the exam is 3 subjects

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

On Saturday:

The number of hours Kiana studied = 2 ¼ hours

This can be written as,

= 2 (1/4)

= 9/4 hours _____(A)

The number of hours studied for each subject.

= ¾ hour ______(B)

The formula for dividing fractions.

= a/b ÷ c/d

= ad/bc

Now,

From (A) and (B) we get,

The number of subjects.

= 9/4 ÷ 3/4

= (9 x 4) / (4 x 3)

= 3 subjects

Thus,

The number of subjects studied for the exam is 3 subjects

Answer:

44 cm³

Step-by-step explanation:

If you break up this shape into 2 pieces you get a rectangle with the measurements of 2, 2, and 5 and another rectangle with the measurements of 2, 2, and 6. You then multiply 2, 2, and 5 together which will get you 20, and multiply 2, 2, and 6 together which will get you 24. You will then add both products which will get you 44. Since the measurement is in centimeters and it is a 3 dimensional shape it will then become 44 cm³.

Answer:

The equation is:

f(x) = Ix + 3I - 2

Step-by-step explanation:

For a function like:

f(x) = Ix - kI + c

k is the x-value where the vertex is, and c is the y-value where the vertex is.

In the graph we can see that the vertex is in the point (-3, -2)

then:

x-value = -3 = k

y-value = -2 = c

Replacing those in the equation for the function:

f(x) = Ix - (-3)I - 2

f(x) = Ix + 3I - 2

Answer:

Each side of the original triangle is 1/2 the length of each side of the scale drawing

Step-by-step explanation:

The scale drawing was created using a factor of 2 ⇒ each side of the original triangle was multiplied by 2 ⇒ the original triangle lengths are half the size of the scale drawing

Answer:

Each side of the original triangle is 2 times the length of each side of the scale drawing.

Answer:

the value of this increase in percentage indices is 27.77%

Step-by-step explanation:

The computation of the  value of this increase in percentage indices is shown below:

Given that

The population has increase from 82,350 to 105,200

So, the increase in percentage would be

= (105,200 - 82,350) ÷ (82,350)

= 22,850 ÷ 82,350

= 27.77%

Hence, the value of this increase in percentage indices is 27.77%

Answer:

Answer is

(100*-m)+(45*n)

Step-by-step explanation: because stock  decreases per sock so you're going to multiply 100 times -m because it is decreasing so it will be negative

Then it will be 45*n because it increases per number of stocks so you multiply 45 which is the number of stocks times n

Step-by-step explanation:

Answer:

7,680

Step-by-step explanation:

Okay, so we use PEMDAS right, so we start with the parenthesis:

6 + 20 = 26

300 x 26 = 7,800

7,800 - 120 = 7,680

So 300(6+20)-120=7,680
