The print shop charges $1. 10 per square foot for banners of any shape and size. What is the approximate cost of the banner before tax? $41. 95 $46. 14 $83. 90 $92. 30.
The approximate cost of the banner which is charged by print shop before tax is 92.30.
What is cost price per unit?The cost price per unit is the amount of money required to buy one uni of a brand or goods.
To find the cost price per unit, divide the total amount of cost of the goods to the total number of goods.
The length of the sides of parallelogram banner which order by Jace is 9 feet and the length of the bottom side is 12 feet.
The length of the diagonal is 19 ft. The parimeterof the triangle made by this sides is,
[tex]s=\dfrac{9+12+19}{2}\\s=20[/tex]
Using Heron's formula, the area of this triangle is,
[tex]A=\sqrt{20(20-9)(20-12)(20-19)}\\A=\sqrt{20\times11\times8\times1}\\A=41.95\rm ft^2[/tex]
Now the area of the banner is,
[tex]A=41.95\times2\\A=83.90\rm ft^2[/tex]
The print shop charges $1.10 per square foot for banners of any shape and size.Thus, the charge of the banner with area 108 square foot is,
[tex]P=1.10\times83.90\\P=92.29\\P\cong92.30[/tex]
Thus, the approximate cost of the banner which is charged by print shop before tax is 92.30.

Which expression is equivalent to -3 ( x - y )?
A. -3x + y
B. -3x - y
C. -3x - 3y
D. -3x + 3y
I already know it’s not A or B
Answer:
D. -3x+3y
Step-by-step explanation:
Start by distributing the -3 to each term in the parentheses:
-3(x)+(-3)(-y)
Here are some multiplication sign rules that will make this problem easier:
- - make a +
- + make a -
+ - make a -
+ + make a +
-3x+3y (note that since both 3 and y are negative, they make a positive)
Can anyone please help me with this??? I really need it );
Answer:
(x,y) (9,4)
Step-by-step explanation:
-2x+7y = 10
x -3y = -3 (move x to the other side)
-2x +7y = 10
x = -3 + 3y (put in for x)
-2 (-3 +3y) +7y =10 ( slove for y)

Adult tickets to the faculty-students basketball game sold for $5 each and student ticket was sold for $2 each. if 235 tickets were sold for a total of $725, how many of each kind of ticket were sold?
Answer:
85 adult tickets
150 children tickets
Step-by-step explanation:
we can write a system of equations and then use the 'elimination method':
let a = adult tickets
let c = children tickets
a + c = 235
5a + 2c = 725
we can multiply the first equation by -5 to get:
-5a - 5c = -1175
now we can add the second equation to get:
5a + 2c = 725
-3c = -450
c = 150
a + 150 = 235
a = 85
10postmen can sort 500 letters in 30 minutes.How many postmen are needed to sort 600 letters in 20 minutes
Answer: 18
Step-by-step explanation:
We want to find out how many letters each postman can sort in an hour to make the process easier. Since we're already told that 10 postmen can sort 500 letters in 30 minutes, we can use that info to find that each postman can sort 100 letters per hour as 10 postmen would be able to sort 1000 letters in 1 hour.
Then, we can apply this info to find out how many postmen can sort 600 letters in 20 minutes. We can multiply the time and task each by 3 to find that this is the same rate as sorting 1800 letters in 1 hour, so the answer is 18 postmen.

Solve square root of x + square root of x+2 = 2
The value of x is [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Given:
[tex] \sqrt{x} + \sqrt{x + 2} = 2[/tex]
Rearranging the radical on left side,
[tex]\sqrt{x + 2} = 2 - \sqrt{x}[/tex]
Power on both sides,
[tex](\sqrt{x + 2})^{2} = (2 - \sqrt{x})^{2} [/tex]
Simplifying the left,
[tex]x + 2 = (2 - \sqrt{x} )^{2}[/tex]
For the RHS equation, use the property of (a-b)² = (a²-2ab+b²),
[tex] = > x + 2 = {2}^{2} - (2 \times 2 \sqrt{x}) + ( \sqrt{x})^{2} [/tex]
Now calculating its powers,
[tex] = > x + 2 = 4 - 4\sqrt{x} + x[/tex]
Now sending -4√x to the LHS (left side), its sign becomes plus (+),
[tex] = > 4 \sqrt{x} = 4 + x - x - 2[/tex]
Now the +x and -x will be cancelled,
[tex] = > 4 \sqrt{x} = 4 - 2[/tex]
[tex] = > 4 \sqrt{x} = 2[/tex]
Bringing 4 to the right side, it becomes the denominator,
[tex] = > \sqrt{x} = \frac{2}{4} [/tex]
[tex] = > \sqrt{x} = \frac{1}{4} [/tex]
Now powering both sides,
[tex] = > ( \sqrt{x})^{2} = ( \frac{1}{2})^{2}[/tex]
[tex] = > x = \frac{1}{4} [/tex]

A rectangular garden has an area of 52 square yards. If we multiply its
length and width by 15, what is the area of the new rectangle?
OA) 1540 yd.?
OB) 12,270 yd.?
OC) 11,700 yd?
OD 270,000 yd?
Please answer soon!
Answer:
It is OC) 11,700 yd.
Step-by-step explanation:
when finding new area, take you 2 numbers, 52 and 15, square the 15, then multiply them 52 x 15^2 = 11,700
Answer:
C) 11, 700 yd²
Step-by-step explanation:
Let [tex]x[/tex] = width of a rectangle
Let [tex]y[/tex] = length of a rectangle
Area of a rectangle = width x length
⇒ area = [tex]xy[/tex]
If a rectangular garden has an area of 52 yd²
⇒ [tex]xy[/tex] = 52
If the length and width are multiplied by 15:
⇒ new width = [tex]15x[/tex]
⇒ new length = [tex]15y[/tex]
⇒ area = [tex]15x \times 15y=225xy[/tex]
If xy = 52,
new area = 225xy = 225 x 52 = 11700
Pankaj borrows rupees 57,000 to buy a used car and is charged the rate of interest 6% per annum. if the term of his borrowing is 4 years, how much interest does he pay?
Rs.13680 is the answer.
Step-by-step explanation:-
Given-
•Principal (P) = Rs.57,000
•Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
•Time (n) = 4 years
Applying Interest formula,
[tex]→In=P \times R \times T[/tex]
[tex]→57,000 \times 0.06 \times 4[/tex]
[tex]→Rs.13680[/tex]
Hence, the interest is Rs.13680

How will you use the rules of adding, subtracting, multiplying and dividing rational numbers with simplifying algebraic expressions?
Answer:
I would use addition, subtraction, multiplication, and division in terms of taxes, interest rates, my fixed salaries, and so forth. And dividing rational numbers would be like 10% of the interest rate or 11% of the interest rate. I can also simplify the algebraic expressions to make the terms easier for me in my head.

The quartiles of any Normal distribution are about __________ standard deviations from the mean. Give your answer to 3 decimal places.
Answer:
(1) The first quartile of standard normal distribution is -0.67.
(2) The third quartile of standard normal distribution is 0.67.
(3) The percentage of the observations in the standard normal distribution that are suspected outliers is, 0.74%.
Explanation:
A standard normal distribution has mean 0 and variance 1.
(1)
The first quartile of any data is the value below which 25% of the data lie.
That is, P (Z < z) = 0.25.
The value of z is -0.67.
Thus, the first quartile of standard normal distribution is -0.67.
(2)
The third quartile of any data is the value below which 75% of the data lie.
That is, P (Z < z) = 0.75.
The value of z is 0.67.
Thus, the third quartile of standard normal distribution is 0.67.
(3)
In case of a standard normal distribution values lying outside the range
(Q₁ - 1.5 IQR, Q₃ + 1.5 IQR)
are considered as outlier.
Compute the range as follows:
Compute the probability of (Z < -2.68) and P (Z > 2.68) as follows:
The probability of a value being an outlier is,
P (Outlier) = P (Z < -2.68) + P (Z > 2.68)
= 0.0037 + 0.0037
= 0.0074
The percentage of the observations in the standard normal distribution that are suspected outliers is, 0.0074 × 100 = 0.74%.

Circle graphs are used to represent data in percentages and proportions
There are 25 salads in the restaurant shelf
How to determine the total saladsFrom the question, we have:
The number of Caesar salad = 15The percentage of Caesar salad = 60%So, the total number of salad is:
n * 60% = 15
Divide both sides by 60%
n = 25
Hence, there are 25 salads in the restaurant shelf
