Answer:

36.2

Step-by-step explanation:

144.8/4 = 36.2

The answer is 36.2 when 144.8 divided by 4.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

/ Division operation: Divides left-hand operand by right-hand operand

For example 12/2 = 6

Given that digit as :

If the denominator is 144.8, the numerator can be taken as 4, so the fraction would become as:

⇒ 144.8/4

⇒ 36.2

Hence, the answer is 36.2 when 144.8 divided by 4.

Hi there!

An equation to represent how he got $460.65 as take home pay is:

15x - (.17× (15x) ) = 460.65

15x tells us how much money he earned in total. We also multiply that by .17 to determine how much goes to taxes. Then, we subtract taxes from total, and put that equal to our take home pay

Answer:

3 3/8 cups of flour

Step-by-step explanation:

So, we know that 2 1/4 is the normal amount of flour you would use in the recipe. but you don't want to do normal. You want to make 1 1/2 times more than you usually do.

To do this, first figure out what half of 2 1/4 is.

(2 1/4) /2 = 1 1/8

Then, because you are looking to use 1 1/2 times more flour, simply add the 1 1/8 to the 2 1/4

You end up using 3 3/8 cups of flour.

Answer:

81, 243, 729, 2187, 6561

Step-by-step explanation:

Note that the

third term 9 = 3²

fourth term 27 = 3³

Thus to obtain a particular term in the sequence we require the exponent to be one less than the terms position n in the sequence, that is

[tex]a_{n}[/tex] = [tex]3^{n-1}[/tex] , thus

first term 1 → [tex]3^{1-1}[/tex] = [tex]3^{0}[/tex] = 1

The next 5 terms in the sequence are

[tex]a_{5}[/tex] = [tex]3^{5-1}[/tex] = [tex]3^{4}[/tex] = 81

[tex]a_{6}[/tex] = [tex]3^{6-1}[/tex] = [tex]3^{5}[/tex] = 243

[tex]a_{7}[/tex] = [tex]3^{7-1}[/tex] = [tex]3^{6}[/tex] = 729

[tex]a_{8}[/tex] = [tex]3^{8-1}[/tex] = [tex]3^{7}[/tex] = 2187

[tex]a_{9}[/tex] = [tex]3^{9-1}[/tex] = [tex]3^{8}[/tex] = 6561

Answer: Option A.

Step-by-step explanation:

The first step is to place the point of the compass in the vertex of the angle and draw an arc that connects both rays.

Then you put the compass in the points where the arc intersected the rays and draw two new arcs (with the radius of the compass constant)

The point where the two new arcs intersect will be the interior point.

Then the first step is: place the compass in the vertex of the angle.

The vertex is the common point to the two rays, in this case, we can see that the vertex is the point A.

Then you should place the compass in the point A, the correct option is option A.

Step-by-step explanation:

f(t)=-2t^2+ 1

f(-3)=-2*-3^2+1

f(-3)=-2*9+1

f(-3)=-18+1

f(-3)=-17

The value of the function f(t)=-2t²+ 1 for f(-3) will be - 17.We can find the value of f(-3) by putting -3 at the place of t

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range. In mathematics, functions serve as the fundamental building blocks for developing technology.

It is given that the function is,

f(t)=-2t²+ 1

We have to find the value of the function as t=-3.

We can find the value of f(-3) by putting -3 at the place of t and applying the arithmetic operation as,

f(t)=-2t²+ 1

f(-3)=-2(-3)²+1

f(-3)=-2(9)+1

f(-3)=-18+1

f(-3)= -17

Thus, the value of the function f(t)=-2t^2+ 1 for f(-3) will be -17. We can find the value of f(-3) by putting -3 in the place of t.

Answer:

B.  9

Step-by-step explanation:

18 per two hours. 18 divided by 2= 9.

Complementary angles are two angles that add up to 90 degrees

So, 2x + 3x = 90 we have to solve for x

5x = 90

Divide each side by 5

x = 18

Plug 18 into x for 3x and 2x

3x = 3(18) = 54

2x= 2(18) = 36

Step-by-step explanation:

Answer:

$15

Step-by-step explanation:

1 chocolate cake and 6 egg tart costs $18.60.

1 chocolate cake and 24 egg tarts cost $29.40.

Find the difference in egg tarts first.

Difference in egg tarts = 24 - 6 = 18

Then, the difference in cost.

$29.40 - $18.60 = $10.80

Find the cost of 1 egg tart.

18 egg tarts = $10.80

18 egg tarts = $10.80

1 egg tart = $10.80 ÷ 18 = $0.60

To find the cost of a chocolate cake, you minus the cost of 6 tarts from $18.60.

6 egg tarts = $0.60 × 6 = $3.60

6 egg tarts = $0.60 × 6 = $3.601 chocolate cake = $18.60 - $3.60 = $15

Answer:

f(x) = 9x - 1,200

Step-by-step explanation:

Let x represent the number of movie tickets sold.

9x will represent the profit made from selling movie tickets that day, since each ticket is 9 dollars.

To determine the profit, subtract 1,200 from 9x.

9x - 1,200 will represent the profit. Turn this into a function:

f(x) = 9x - 1,200 where x is the number of movie tickets sold and f(x) is the profit
