You multiply 7.50 by 40 and get 300, then you multiply 6 times 40 and get 240, and you will add 300 plus 240 and get 540
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.

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 triangle has angles of 124, 28° and 28º. Using the given angle measures, how many triangles can be formed?
Answer: 340
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.

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
Which ratio is equivalent to the ratio 33:39?
The ratio which is equivalent to 33:39 is 11:13
Equivalent ratioAn equaivalent ratio are fraction whose value are equal and are integral multiples of each other.
For example 1:2 = 2:4
Since 1:2 = 1 × 2 : 2 × 2 = 2 : 4
Also, 2:4 = 2 ÷ 2: 4 ÷ 2 = 1 : 2
We see that 1:2 and 2:4 are equivalent since we multiply 1:2 by 2 to get 2:4 or divide 2:4 by 2 to get 1:2.
Finding the equivalent ratio to 33:39So, to find the ratio equivalent to 33:39, we write 33:39 in its simplest terms.
So, 33:39 = 11 × 3 : 13 × 3
= 11 : 13
So, the ratio which is equivalent to 33:39 is 11:13

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

When Carla looked out at the school parking lot, she noticed that for every 2 minivans, there were 5 other types of vehicles. If there are 161 total vehicles in the parking lot, how many of them are minivans?
Answer:
46 of the total vehicles are minivans
Step-by-step explanation:
Let the number of minivans be x
and the number of other types of vehicles be y
From the question,
Carla noticed that for every 2 minivans, there were 5 other types of vehicles.
This means the ratio of minivans to other types of vehicles is 2:5.
Therefore,
x:y = 2:5
We can then write that
x/y = 2/5
∴ 5x = 2y ...... (1)
Also from the question,
There are 161 total vehicles in the parking lot
That is
x + y = 161 ...... (2)
From equation (2), we can write that
y = 161 - x
Put this into equation (1)
5x = 2y
Then
5x = 2(161-x)
5x = 322 -2x
5x+2x = 322
7x = 322
x = 322/7
x = 46
Since x represent the number of minivans
Hence, 46 of the total vehicles are minivans.
