how much is 3/4 of $2.99

Answer:

r = 155°

s = 25°

t = 155°

Step-by-step explanation:

25° is supplementary to <r. Therefore:

m<r + 25° = 180°

m<r = 180 - 25

m<r = 155°

25° and <s are vertical opposite angles. Vertical angles are congruent. Therefore, m<s = 25°

<r and <t are vertical opposite angles, therefore, they are congruent.

m<t = m<r = 155°

Answer:

Step-by-step explanation:

For sales of N copies at  $90 each, 90N is added to Dale's base salary of $1800.

  P = 90N +1800

__

For N=23, Dale's salary would be ...

  P = 90(23) +1800 = 2070 +1800 = 3870

Dale's total pay for selling 23 copies would be $3870.

Answer:

9 downloads

Step-by-step explanation:

Let's start by subtracting the initial fee of $9.99 from her total bill of $10.89.

$10.89 - $9.99 = $0.90

Now, let's divide her total cost of downloads by the individual cost of downloads.

$0.90/$0.10 = 9

Nia made 9 downloads last month.

Addition Property of Equality  ----If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.

Commutative property of addition- changing the order of the numbers we are adding, does not change the sum. Here's an example of how the sum does NOT change, even if the order is changed

The properties that can be used to solve 7y - 15 = -29 are

Addition property of equality and inverse property of multiplication.

Given equation is 7y - 15 = -29.

We will solve for y and see which of the given following properties are applied.

Addition property of equality

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.

Inverse property of multiplication

It states that every non-zero x multiplied with 1/x will equal 1.

Solve for y.

7y - 15 = -29

We will add 17 on both sides of the equation.

7y - 15 + 15 = -29 + 15

7y = -14

Now, multiply 1/7 into both sides of the equation.

7y / 7 = -14 / 7

y = -2

While solving for y we see that we have to use the addition property of equality and inverse property of multiplication.

Plz mark ice bear Brainliest

Two angles that have the same measure are called congruent angles

Two angles having the same degree of measurement are said to be congruent.

A protractor can be used to compare the angle measures of congruent angles, or angle relationships and properties can be used to find congruent angles in a variety of geometric shapes. Because they enable us to recognize and address issues concerning parallel lines, triangles, polygons, and other geometrical shapes, congruent angles are crucial in the study of geometry.

In order to work with angles and their properties in mathematics, one must first understand congruent angles.

A) 2210.56 cubic units

Answer:

21

Step-by-step explanation:

3n - 15 - 6 + 2n = 4n

3 n + 2n = 4n + 15 + 6

5 n - 4n = 15 + 6

n = 21

Answer:

 n = 21

Step-by-step explanation:

Use distributive rule: a(b + c) = a*b + a*c

3(n -5) - (6 - 2n) = 4n

3*n - 3*5 + 6*(-1) - 2n *(-1) = 4n

3n  - 15 - 6 + 2n = 4n             {add like term in LHS}

3n + 2n - 15 - 6 = 4n

            5n - 21  = 4n              {add 21 to both sides}

       5n -21 + 21 = 4n +21

                     5n = 4n + 21         {subtract 4n from both sides}

             5n - 4n = 4n -4n +21

   n = 21

Answer:

C. 10n

Step-by-step explanation:

The figure has 2 sides with length 4n and 2 sides with length n.

perimeter = 4n + 4n + n + n

perimeter = 10n

The perimeter of the figure is 10n. which is the correct answer would be option (C).

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

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that the figure has 2 sides with length 4n and 2 sides with length n.

The perimeter of the figure = 4n + 4n + n + n

Apply the addition operation in the above equation, we get

The perimeter of the figure = 10n

Therefore, the correct answer would be an option (C).

Answer:

1.) 14.09 m/s

2.) 6.9 m/s

Step-by-step explanation:

Given that the boat is pointing North and can typically move at a speed of 12.8 m/s in calm waters. The boat travels through water where there is a 5.9 m/s current flowing to the East.

The speed of the boat relative to a stationary observer on land will be achieved by using pythagorean theorem

V^2 = 12.8^2 + 5.9^2

V^2 = 198.65

Square root both sides

V = 14.09 m/s

2.) If the boat turns to face directly West.

Since the boat can move at speed 12.8 m/s in a calm water, the speed of the boat if it face west will be

12.8 - 5.9 = 6.9 m/s

Therefore, the boat is moving relative to land at 6.9m/s

Answer:

total commission= $2,600

Step-by-step explanation:

Giving the following information:

He earns a 10 percent commission on the first $5,000 and 15 percent on all sales over $5,000.

First, we need to structure the total commission formula:

total commission= 0.10*x + 0.15*y

X= sales up to $5,000

Y= sales from $5,001 to infinity

Now, sales for $19,000 sales:

total commission= 0.1*5,000 + 0.15*14,000

total commission= $2,600
