Answer:
$120
Step-by-step explanation:
Since after $20 coupon, the price become $100, then before it was
(20 + 100) = $120
Thenks and mark me brainliest :)
Answer:
One regular price ticket cost $40
Step-by-step explanation:
First yo would have to add back the $20 that they saved to the total which would be $120 total and then since that was the total for all 3 of them you would do $120 divided by 3 which would be $40 for each ticket regularly.
Scores for a common standardized college aptitude test are normally distributed with a mean of 496 and a standard deviation of 110. Randomly selected men are given a Test Preparation Course before taking this test. Assume, for sake of argument, that the preparation course has no effect. If 1 of the men is randomly selected, find the probability that his score is at least 545.7. P(X > 545.7)
Answer:
0.3257
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 496 ; Standard deviation = 110
For :
P(x > 545.7)
We obtain the standardized, Z score
Z = (545.7 - 496) / 110
Z = 49.7 / 110
Z = 0.4518
Hence, using the Z distribution table :
P(Z > 0.4518) = 1 - P(Z < 0.4518)
P(Z > 0.4518) = 1 - 0.67429
P(Z > 0.4518) = 0.32571
Bryce, a top landscape architect, was given a special garden design job. The client owned a property as shown below, in which he wanted to have four separate small gardens, each of them exactly the same size and shape. In other words, “congruent.” Remember, all four gardens must fit exactly within the shape of the property as shown below; you can’t change the dimensions of the property or move things around - you have to keep your design within the original shape. Bryce came up with an ingenious design that fit the client’s request exactly. Can you figure out what his design was?

find the slope, and in y=mx+b form
9514 1404 393
Answer:
slope: 1y = x +6Step-by-step explanation:
The slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
Using the first two table entries, this is ...
m = (5 -4)/(-1 -(-2)) = 1/1
m = 1
The y-intercept can be found using the formula ...
b = y1 -m·x1
b = 4 -(1)(-2) = 6
Then the slope-intercept equation is ...
y = mx + b
y = x + 6
The slope is 1; the equation is y = x+6.
Answer:
the answer is
slope:1
y=x+6
Find the total surface area of this square based
pyramid.
1077
10 ft
[? ]ft2
Enter
Answer:
300ft^2
Step-by-step explanation:
Total surface area = Area of base + (1/2) x perimeter of base x slant height
Area of base = length² = 10 x 10 = 100
Perimeter of base = 2 ( length + breadth)
2 x 20 = 40
slant height = 10
100 + (1/2) x 40 x 10 = 300 ft^2
A local pizza shop has a membership program for frequent buyers. The membership costs $5 per month and members get a discounted price of $2 per slice of pizza. Aisha purchased a membership to this pizza shop. How much would Aisha have to pay the pizza shop if she bought 8 slices of pizza this month? What would be the monthly cost for
x slices of pizza?
Answer:
Aisha would pay 21 dollars for 8 slices.
Equation 2x(x=number of slices)+5
Step-by-step explanation:
Rewrite the quadratic function below in Standard Form.
y = (x - 4) (x + 3)
the standard form of a quadratic formula is
y = ax^2 + bx + c
in this case you will solve using foil method
(× - 4)(x + 3)
(x × x) +( x × 3 )(- 4 × x) ( -4)× 3))
x^2 + 3x - 4x -12
x^2 - x - 12
therefore
y = x^2- x - 12

If YV = 28 in, find the length of VYX.
Answer:
B) 68.91 inches
Step-by-step explanation:
To start, lets define what we are trying to find. VYX is the major arc VX, spanning from V to X crossing over Y.
We are also given that the diameter is 28 inches.
Since arc length and area are proportional to the central angle, we can create the following equality:
angle of VYX/360 = arc length of VYX/circumference
We know that the central angle of VYX = central angle of minor UV + UYX = 117 + (180-15) = 282 degrees.
282/360 * 28*pi = arc length of VYX
Thus, the length of VYX = 68.90559887 inches
Thus, the correct answer is B, 68.91 in.

Answer:
The solution to these question can be defined as follows:
Step-by-step explanation:
[tex]H_0: \mu = 33 \ versus\\\\ H_a: \mu > 33\\\\\bar{X} = 33.11\\\\S = 4.7468\\\\n = 47\\\\df = n - 1 = 46\\\\\alpha = 0.05\\\\[/tex]
Testing statistic:
[tex]t = \frac{(\bar{X} - \mu)}{[\frac{S}{\sqrt{(n)}}]}[/tex]
[tex]= \frac{(33.11 – 33)}{\frac{4.7468}{\sqrt{47}}}\\\\= \frac{0.11}{0.6924}\\\\= 0.1589\\\\P-value = 0.4372\\\\P-value > \alpha = 0.05[/tex]
Therefore the null hypothesis we do not deny, it is not clear enough so that the median age once British men get engaged is higher than in 2013.

[tex]\tan (30 + 60) = unde f ined[/tex]
Step-by-step explanation:
Given
[tex]\tan (A + B) = \frac{\tan A + \tan B}{1 - \tan A * \tan B}[/tex] ---- right expression
[tex]A = 30^o; B = 60^o[/tex]

Solve
[tex]\tan (A + B) = \frac{\tan A + \tan B}{1 - \tan A * \tan B}[/tex]
Substitute: [tex]A = 30^o; B = 60^o[/tex]
[tex]\tan (30 + 60) = \frac{\tan 30 + \tan 60}{1 - \tan 30 * \tan 60}[/tex]
In radical forms, we have:
[tex]\tan (30 + 60) = \frac{\sqrt 3/3 + \sqrt 3}{1 - \sqrt 3/3 * \sqrt 3}[/tex]
[tex]\tan (30 + 60) = \frac{\sqrt 3/3 + \sqrt 3}{1 - 1}[/tex]
[tex]\tan (30 + 60) = \frac{\sqrt 3/3 + \sqrt 3}{0}[/tex]
[tex]\tan (30 + 60) = unde f ined[/tex]

The polygon has 15 sides.
The length of each side is 8 cm.
The exterior angle of the polygon is x.
BRC is a right-angled triangle.
Calculate the length of BR.
Thanks in advance
Answer:
BR is about 7.3084 cm
Step-by-step explanation:
the sum of the exterior angles of any polygon is 360. The measure ox x would be 360/15= 24
since I want BR, I will use cos (adj/hyp)
cos24=s/8
.9135=s/8

Again, suppose you were to draw all possible samples of size 36 from a large population with a mean of 650 and a standard deviation of 24. You then compute the sample mean x-bar for each sample. From the long list of sample means, you create the sampling distribution of the sample mean, assigning probabilities to all possible values of x-bar. What value should you show at the center of the distribution
Answer:
Following are the solution to the given question:
Step-by-step explanation:
Please find the complete question in the attached file.

A 2-kilogram bag of potting soil costs $1.96. What is the unit price?
Answer:
The unit price is $0.98
Answer:
98¢
Step-by-step explanation:
The unit price of an item is the price of one unit. In this case, this would be the price of a single kilogram.
To find the unit price, we'll divide the given price by the amount of units it is for. So, divide 1.96 by 2.
1.96 ÷ 2 = unit price
0.98 = unit price
This means the price of a single kilo of potting soil is $0.98. The unit price of the potting soil is 98 cents.
Good luck :)
PLEASE HELP ASAPPPPP Find the value of x for mAB= 27° and mCD= 49°. The figure is not drawn to scale
Answer:
Step-by-step explanation:
The other guy has mislead other people. If i turned my thing in, I would have gotten a 90% instead of 100%.
It is A.
38 degrees.
The measure of x is (a) 38 degrees
The given parameters are:
[tex]mAB = 27^o[/tex]
[tex]mCD = 49^o[/tex]
The measure of x, is the average of angles AB and CD.
So, we have:
[tex]x = \frac{mAB + mCD}{2}[/tex]
Substitute known values of AB and CD in the above equation.
So, we have:
[tex]x = \frac{27^o + 49^o}{2}[/tex]
Add 27and 49
[tex]x = \frac{76^o}{2}[/tex]
Divide 76 by 2
[tex]x = 38^o[/tex]
Hence, the measure of x is (a) 38 degrees
