Solve the question.
A department store is offering the same percentage discount on all of their shoes. Suppose one pair of shoes is marked down from $70 to 549. Based on that percentage discount, what would the new price
for a pair of shoes that originally cost $110?
A89.00
B.77.00
C.73.33
D.33.00
O
Answer:
B.77.00Step-by-step explanation:
Note: there is typo- 549 should read $49
Discount is:
$70 - $49 = $21Discount % is:
21/70*100% = 30%Applying same discount to pair of shoes for $110:
$110 - 30% =$110*(100 - 30)/100 = $110*0.7 =$77Correct option is B
stan earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday evening. He earned $160 in all. To the nearest hour, what is the least number of hours Stan would have to work to earn this much money?
Answer:
8 hours
Step-by-step explanation:
Calculator 60 divided by 7.55= 7.94 round to 8
The amount of time Stan works to earn $160 will be 7.94 hours.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Stan earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday evenings. He earned $160 in all.
The working time will be calculated by making an equation assuming the working time to be x hours.
7.55x + 100 = 160
7.55x = 160 - 100
7.55x = 60
x = 60 / 7.55 = 7.94 hours.
Therefore, the amount of time Stan works to earn $160 will be 7.94 hours.

Jon ate too many holiday cookies and gaines 2.2 kilograms in December. Then he went on a diet and lost 1.5 kilograms in January. Then he lost another 3.7 kilograms in February. Jon wants to know what the total change in his weight was over these three months.
WICH OF THE FOLLOWING EQUATIONS MATCHES THE SITUATION ABOVE?
A.) 2.2+(-1.5)+(-3.7)=?
B.) 2.2+1.5-3.7=?
c.) None of the above
Answer:
A
Step-by-step explanation:
This problem is completing our example from the end of the recording today.) We have a 20 foot ladder and lean it against the house at a 75 degree angle with the ground. a) How far up the house does the ladder reach? b) How far from the house is the bottom of the ladder?
Answer:
a) The ladder reach 19.32 foot up the house
b) The bottom of the ladder is 5.18 foot from the house
Step-by-step explanation:
An illustrative diagram of the scenario is attached below.
From the diagram, we have a right angle triangle with the length of the ladder being the hypotenuse. The opposite indicates how far up the house the ladder reach and the adjacent indicates the distance of the bottom of ladder from the house.
a) To determine how far up the house the ladder reach, that is the opposite. Let the opposite be y
From the formula
Sinθ = Opposite / Hypotenuse
Where θ is the angle subtended
Here θ = 75°
Hypotenuse = 20 foot
∴ sin75° = y / 20
y = 20 × sin75°
y = 20 × 0.9659
y = 19.32 foot
Hence, the ladder reach 19.32 foot up the house.
b) To determine how far from the house the bottom of the ladder is, that is the adjacent. Let the adjacent be x
From the formula
Cosθ = Adjacent / Hypotenuse
Where θ is the angle subtended
Then,
cos75° = x / 20
∴ x = 20 × cos75°
x = 20 × 0.2588
x = 5.18 foot
Hence, the bottom of the ladder is 5.18 foot from the house.

Write a system of linear equations for the graph below.
Answer:
y=-1/2x+2
y=-3x-3
Step-by-step explanation:
Slope is rise/run, so finding slope is looking at y/x of the lines in between two points.
Then finding the y-intercept you look along the y-axis where the line passes through and what the value there is (look out for positive or negative!).
A monthly budget is shown. Which equation can be used to determine y, the minimum amount of money a family must earn to meet the requirements of this budget for one year?
Answer:
$3600 * 12
Step-by-step explanation:
To get the minimum amount of money the family must earn to meet the requirements of their budgets for one year, first you have to get their total budget for a month and then multiply it by the number of months in a year.
The monthly budget = Rent + food + child care + transportation + utilities + insurance + savings + taxes
Monthly budget = $870 + $550 + $375 + $480 + $400 + $235 + $400 + $290 = $3600
Minimum requirements for one year = $3600 * 12 months

Write the equation in standard form of the line that passes through (-1,-4) parallel to 9x -y = 4
Answer:
9x-y=-5
Step-by-step explanation:
First, put this equation into slope intercept form (makes it easier)
9x-y=4
subtract 9x from both sides
-y=-9x+4
multiply by -1 on both sides
y=9x-4
Parallel lines have the same slopes, so the second line is y=9x+b (b is a placeholder for the y intercept)
now, find the y intercept
since the line has to go through (-1,-4), plug it into the equation
-4=9(-1)+b
-4=-9+b
5=b
so now the line would be y=9x+5... in slope intercept form. The question asks for the answer to be in standard form.
5 from both sides
y-5=9x
subtract y from both sides
-5=-y+9x
or
9x-y=-5
