Step-by-step explanation:
Step one:
given data
A store buys a shirt from the vendor for $15
The store makes a 55% profit
Required
The sale price of the shirt
Step two:
Percent profit= sale-cost price/cost price *100
subtitute
55= sale-15/15 *100
0.55= sale-15/15
cross multiply
sale-15= 0.55*15
sale-15=8.25
sale= 8.25+15
sale=$23.25
What expression makes the equation true? (Photo found below)
What is the mean, median, mode, and range of 10,14,15,15,16,22,22,22,24,24,27,31,32,37,40,44.
Answer:
mean 16.75
median 15.5
mode 13
range 16
Answer:
25.5 is the median, 22 is the mode, 24.7 is the mean and 34 is the range
Step-by-step explanation:
mean is the average, you get this by adding up all the numbers and then dividing the total by the amount of numbers there are.
the median is the number with the middle value, in this case there were 2 medians because the was an even number of numbers so you average the medians
mode is the number the occurs the most out of the whole set. For example in this case all the numbers occurred twice except 22 which occured 3 times
Last is the range which takes the highest number and subtracts it by the lowest number. It's just that simple!

A delivery company has 18 vehicles in its fleet.
It has 8 vans and 10 trucks.
All 18 vehicles are on the road every working day.
The company is reviewing its fuel expenses and therefore
gathers some information about each type of vehicle.

£1.29 per litre.
Truck

6.2
Use this information to work out the total fuel bill for 1 working day.
You must show all your working.
Answer: £1517.04
Step-by-step explanation:
The fuel expenses for the vans will be calculated as:
Vans:
Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:
= 198/9
= 22 litres
Since there are 8 vans, they'll use:
= 22 × 8 = 176 liters
Trucks:
Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:
= 620/6.2
= 100
Since there are 10 trucks, they'll use:
= 100 × 10 = 1000 liters
The amount of liters for both the van and the truck will be:
= 176 liters + 1000 liters
= 1176 liters
The fuel cost will then be:
= 1176 × 1£1.29
= £1517.04
Determine the number and types of solutions for
6m^2-3m-4=0
Given:
The equation is
[tex]6m^2-3m-4=0[/tex]
To find:
The number and types of solutions for the given equation.
Solution:
We have,
[tex]6m^2-3m-4=0[/tex]
It is a 2nd degree polynomial because the highest degree of the variable x is 2.
Number of solutions = Degree of the polynomial
Number of solutions = 2
Therefore, the given equation has 2 solutions.
In a quadratic equation [tex]ax^2+bx+c=0[/tex], if [tex]b^2-4ac>0[/tex], then the equation has two distinct real solutions.
For the given equation, a=6, b=-3 and c=-4.
[tex]D=b^2-4ac[/tex]
[tex]D=(-3)^2-4(6)(-4)[/tex]
[tex]D=9+96[/tex]
[tex]D=105>0[/tex]
Therefore, the given equation has two distinct real solutions.
33 is 5% of what number?
Answer:
660
Step-by-step explanation:
We know that .05x=33
To solve this just divide by .05
33/.05=660
Answer:
Let the number be x
[tex]5\% \: of \: x = 33 \\ \frac{5}{100} x = 33 \\ x = \frac{33 \times 100}{5} \\ \boxed{x =660}[/tex]
660 is the right answer.What is this answer? Please help.

Answer:
111.46 units
Step-by-step explanation:
The right triangle has side lengths that are 1/√2 times the hypotenuse length, so each is (18√2)/(√2) = 18 units. The top is this length shorter than the bottom, so the total of all side lengths (CW from left) is ...
18 + (43 -18) +18√2 +43 = 86 +18√2 ≈ 111.46 units

Eduardo opened a credit card at a department store with an APR of 22.29% compounded semiannually. What is the APY on this credit card? (2 points) a 44.58% b 11.15% c 23.53% d 49.55%
Answer:
The correct option is c. 23.53%.
Step-by-step explanation:
The annual percentage yield (APY) can be calculated using the following formula:
APY = (1 + r / n)^n - 1 .............................. (1)
Where;
APY = Annual percentage yield = ?
r = Annual percentage rate = 22.29%, or 0.2229
n = Number of compounding period per year = Semiannually = 2
Substituting the values into equation (1), we have:
APY = (1 + 0.2229 / 2)^2 - 1
APY = 0.2353211025, or 23.53211025%
Rounding to 2 decimal places, we have:
APY = 23.53%
Therefore, the correct option is c. 23.53%.
Express as a trinomial.

How do you know if a point is a solution to a linear inequality
Answer:
To see if an ordered pair is a solution to an inequality, plug it into the inequality and simplify. If you get a true statement, then the ordered pair is a solution to the inequality. If you get a false statement, then the ordered pair is not a solution.

2x+22=5x-20, i need help with the steps and the answer. i suck at these :/
Answer:
x=14
Step-by-step explanation:
2x+22=5x-20
First, subtract 2x from both sides
22=3x-20Then add 20 to both sides
42=3xThen divide by 3 to both sides
14=x
Check your answer:
2(14)+22=5(14)-2050=50Use an inverse matrix to solve the system of equations, if possible.

Four families went out for lunch. The total food
bill came to $167. The families also left a $30 tip for the
waitress. If each family spent the same amount, about how
much did each family spend on dinner? Explain how you
found your answer.
Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though
Use the associative property of addition to write an equivalent expression for (x+17) + y
An equivalent expression is
Answer:
x + (y + 17)
Step-by-step explanation:
The associative property of addition is characterized by altering the order of operations by putting brackets in a different place. The answer will always be the same. Just the order is different.
So one possibility and the one you are likely expected to give is
x + (y + 17)
That means that if 17 and y can be added by giving y a value, then they will be done first.
Then you add z to the result if it has been given a value.
The answer you are expected to give is x + (y + 17)
