Dale is a software salesman. His base salary is S1800, and he makes an additional S90 for every copy of English is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of English is Fun he sells. Write an equation relating P to N. Then use this
equation to find his total pay if he sells 23 copies of English is Fun.
Answer:
P = 90N +1800$3870Step-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:
The ratio of this number to the rectangle’s area is 9:32.
Step-by-step explanation:
The information provided are:
Tom made a square measuring 8 feet by 8 feet.He had 18 friends stand inside it as if they are watching a band at a small club.The area of the square is:

Vectors: A boat moves through the ocean on a foggy day. 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. What is the speed of the boat relative to a stationary observer on land? __m/s Part 2 The boat turns to face directly West. Now how fast is the boat moving relative to land? __m/s
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

Which expression represents the perimeter of this figure?
A. 4n(to the second power)
B. 5n
C. 10n
D. 8n
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).
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
What is the perimeter of the rectangle?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).

What does -3mnp equal?
Answer:
3MN to N =3000000
Step-by-step explanation:
Find r, s, and t and then explain how you got your answer using at least two
vocabulary words (adjacent, complementary, supplementary, vertical).
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°

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

Two angles that have the same measure are called congruent angles
How to determine the termTwo 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.

Quincy Jackson sells motorcycles. He earns a 10 percent commission on the first $5,000 and 15 percent on all sales over $5,000. How much cornmission will he earn on $19,000 in sales?
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

Which properties can be used to solve 7y − 15 = −29? Select all that apply. A. Identity Property of Multiplication
B. Addition Property of Equality
C. Distributive Property
D. Inverse Property of Multiplication
E. Commutative Property of Addition
Answer:
A and E
Step-by-step explanation:
Other 2 wouldn't make sense
Only definite of A
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.
What is addition property of equality and the inverse property of multiplication?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.

Nia has a membership to Apple Music. She pays $9.99 per month and $0.10 per download. If she spent $10.89 last month, how many downloads did she make last month?
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.
