You are offered a job that pays a different amount each day. The
first day, you are paid l¢. The second day you are paid 2¢. The
third day you are paid 4¢. Each day, your pay continues to
double. Write an equation that would describe the amount, in
cents, you would be paid on a particular day.
Answers
Answer:
Salary by day = .01 * 2^(n-1)
where n = # of days so
day 1 = .01 * 2^(1 -1) = .01 * 2^0 = .01
day 2 = .01 * 2^(2 -1) = .01 * 2^1 = .02
day 3 = .01 * 2^(3 -1) = .01 * 2^2 = .04
day 4 = .01 * 2^(4 -1) = .01 * 2^4 = .08

What is the length of A'B'?
A. 6 units
B. 7 units
C. 3 units
D. 4 units
Answers
Answer:
Answer- B, 7 units
Step-by-step explanation:
I took the quiz
A.P.E.X
The length of side A'B' is 7 units, so the correct option is B.
What is the length of A'B'?We know that the side length is invariant under rotations, that means that the equivalent sides of the preimage and the image have equal length, then:
AB = A'B'.
We can see that AB= 7, then we can conclude that the correct option is B.
A'B' = 7 units.

SYSTEMS OF EQUATIONS WORD PROBLEM: The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 500 people. By selling tickets, the members would like to raise $3,350 every night to cover all expenses. Let d represent the number of adult tickets sold at $8.50. Let s represent the number of student tickets sold at $5.50 each. If all 500 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $3,350? At one performance there were two times as many student tickets sold as adult tickets. If there were 360 tickets sold at that performance, how much below the goal of $3,350 did ticket sales fall?
Answers
first question: Number of student's ticket(s) = 400
And number of adult's ticket(d) = 100

Amount invested = Principal = 180,000
Interest rate = 5.75%
Time = 1 year
The interest that is earned at the end of the first year will be:
= PRT

The total cost of a vase of spring flowers at a flower shop depends on the number of flowers ordered. Each flower costs $2.50. Which equation represents the relationship between the total cost, y, to the number of flowers, x?
Answers
Answer:
D. y=2.50x
Step-by-step explanation:
Since the equation asks for the total cost of a vase of flowers (y) that goes on the left side. Each flower costs 2.50 and the flower shop depends on the number of flowers ordered, which makes it a variable. Therefore C is wrong because it has 2.50 as a constant.
The ending equation will be y = 2.50x
Written in context this means that the total cost of a vase of flowers is equal to the cost of each flower (2.50) by how many flowers are ordered.

Find x, the angle of depression from the top of a lighthouse that is 199 ft above water level to the waterline of a ship 1104 ft off shore. Round your answer to the nearest tenth of a degree.
Answers
Answer:
10.2°
Step-by-step explanation:
I'm not sure if my answer is correct and I'm not too good at explaining but I'll try.
The height of the triangle would be 199 ft and it's length would be 1104 ft. Since were looking for the angle of depression, the angle would obviously be outside of our triangle (as shown in the picture). The height and length wouldn't change at all so we can just label the imaginary lines with their corresponding measurements.
The angle that we're looking for is marked in the picture. Since we are given the opposite and the adjacent side, we can use the inverse of tan to figure out our angle, which is 10.2°.
You can also use the "Z" rule and our angle would be where it's shown in the third picture. Nothing would change because our opposite side would still be 199 ft and our adjacent side would still be 1104 ft.

Step-by-step explanation:
Option D is representing the inequality 2(x - 3) - 5x < x-2 on the number line.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R."
It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that the inequality is 2(x - 3) - 5x < x-2. The inequality will be solved as,
2(x - 3) - 5x < x-2
2x - 6 - 5x < x - 2
-3x - 6 < x - 2
-3x - x < 6 - 2

Answers
Answer:
Volume is 285
Step-by-step explanation:
We start by calculating the area of the base
Mathematically, we have a rectangle as the base
So, the area of the base will be;
3.75 * 8 = 30
We now multiply this by the height to get the volume
we have this as:
30 * 9.5 = 285

6) Two boats set off from X at the same
time (below). Boat A sets off on a bearing of 325° and with a velocity of

Calculate the distance between the boats after they have been travelling
for 2.5 hours. Give your answer to the nearest metre.
A
N
X Х
B
Answers
Answer:
The distance between the two boats after 2.5 hours is 57 m.
Step-by-step explanation:
The distance covered by each boat after 2.5 hours are:
speed = [tex]\frac{distance}{time}[/tex]
distance = speed x time
For boat A, speed = 14 km/h and time = 2.5 hrs.
So that,
distance = 14 x 2.5
= 35 km
For boat B, speed = 18 km/h and time = 2.5 hrs.
So that,
distance = 18 x 2.5
= 45 km
The distance between the two boats after travelling 2.5 hours can be determined by applying the cosine rule. Let the distance be represented by x, so that:
[tex]a^{2}[/tex] = [tex]b^{2}[/tex] + [tex]c^{2}[/tex] - 2bc Cos A
[tex]x^{2}[/tex] = [tex]45^{2}[/tex] + [tex]35^{2}[/tex] - 2(45 x 35) Cos [tex]90^{o}[/tex]
= 2025 + 1225 - 3150 (0)
= 3250
x = [tex]\sqrt{3250}[/tex]
= 57.0088
x = 57.0 m
The distance between the two boats after 2.5 hours is 57 m.

How many solutions will this equation have? 2(x + 4) = 2x + 8
Answers
Answer:
None
Step-by-step explanation:
This type of equation is a tautology, it will always be true
We want to see how many solutions does the given equation has.
We will see that the equation has infinite solutions.
The given equation is:
2(x + 4) = 2x + 8
To find how many solutions it has, we need to solve it, we first can distribute the product at the left to get:
2(x + 4) = 2x + 8
2x + 2*4 = 2x + 8
2x + 8 = 2x + 8
Note that we have the exact same thing in both sides, so the value of x can be any real number, and the equation will still be true.
This means that there are infinite solutions for the given equation.
