Answer:
Discount price of T-shirt is $14.40
Regular price of hat is $22.50
Step-by-step explanation:
The regular price, without a discount, of the T-shirt is $18. Since the store offers a discount of 20%, we must remove 20% of the price.
100%-20%=80%. So, the discount price is 80% of the regular price.
18 × 80% = 14.4
So, the discount price of the T-shirt is $14.40.
The hat, on a discount of 20%, costs $18. To find the regular price, we must multiply it by the reciprocal of 80%, which is 100/80, or 1.25.
1.25 × 18 = 22.5
So, the regular price of the hat is $22.50.
find the value of x. write your answer in simplest radical form. x 9 7
Answer:
Answer B
Step-by-step explanation:
You have to use the pythagorean theorm which states that a^2+b^2=c^2
So, 7^2+x^2=9^2
49+x^2=81 subtract 49 from both sides of the equation
x^2=32
x=sqrt(32)
sqrt(32)=sqrt(16)*sqrt(2)
=4*sqrt(2)
Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid
Complete question :
Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid between 15500 and 17000
Answer:
49.85%
Step-by-step explanation:
Mean = 17000
Standard deviation = 500
Obtain the Z score, which is the number of standard deviations from the mean :
((17000 - 17000) / 500) = 0
((15500 - 17000) / 500) = - 3
-3 to 3 = (3 standard deviations)
However,
The value here is (-3 to 0) ; which is only 3 standard deviations to the left.
3 standard deviation = 99.7% (empirical rule)
Since it is only (-3 to 0) ; which is only 3 standard deviations to the left. ; the percentage will be halved
99.7% / 2 = 49.85%
Hence, percentage of buyers who paid between 15500 and 17000 is 49.85%

If sin A = cos B and the measure of angle A is 1.5 times the measure of angle B, find the measure of angle A
Answer:
[tex]A = 54[/tex]
Step-by-step explanation:
Given
[tex]\sin A = \cos B[/tex]
[tex]A=1.5B[/tex]
Required
Find A
If [tex]\sin A = \cos B[/tex]
Then:
[tex]A +B = 90[/tex]
Substitute [tex]A=1.5B[/tex] in [tex]A +B = 90[/tex]
[tex]1.5B + B = 90[/tex]
[tex]2.5B = 90[/tex]
Solve for B
[tex]B = \frac{90}{2.5}[/tex]
[tex]B = 36[/tex]
Substitute [tex]B = 36[/tex] in [tex]A=1.5B[/tex]
[tex]A = 1.5 * 36[/tex]
[tex]A = 54[/tex]

Write an explicate formula for this sequence -2, 6, -18, 54
Answer:
7 =121 and t underscore 15 =193
Step-by-step explanation:
Answer:
[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 6 ÷ - 2 = - 18 ÷ 6 = 54 ÷ - 18 = - 3
This indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 2 and r = - 3 , then
[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]

Which expression represent the product of x3 + 2x - 1 and x4 - x3 + 3
Answer:
x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
Step-by-step explanation:
(x3 + 2x - 1) (x4 - x3 + 3)
= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3
= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
The expression represents the product [tex]x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.[/tex]
We have given that,
[tex]x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
[/tex][tex](x^3 + 2x - 1) (x^4 - x^3 + 3)[/tex]
What is the expression?The expression consists of numbers and arithmetic operators.
It does not contain equality or inequality symbols.
The expression consists of unknown variables.
The expression represent the product of [tex]x^3 + 2x - 1[/tex]and [tex]x^4 - x3 + 3[/tex][tex]= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3[/tex][tex]= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.[/tex]
Therefore, The expression represents the product [tex]x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.[/tex]

What is the volume, in cubic in, of a rectangular prism with a height of 11in, a width of 15in, and a length of 2in?
Plz help me out thanks
Answer:
360 cubic units
Step-by-step explanation:
height = 4 units
length = 10 units
breadth = 6 units
Volume of a cuboid = l × b × h
V = 10 × 6 × 4
V = 10 × 24
V = 240 cubic units
Now a scale factor of 1.5 units is applied to the dimensions,
new volume = 240 × 1.5 = 360
∴ New volume of the prism = 360 cubic units
Answer:
240 cubic units

6) find the value of x such that the data set has the given mean
100, 121, 105, 113, 108, X ; mean = 112.
Answer:
x = 135
Step-by-step explanation:
(100 + 121 + 105 + 113 + 108 + x) /6 = 112
(547 + x) /6 = 112
547 + x = 112 × 6
547 + x = 672
x = 672 - 547
x = 135

Answer:
B. (1, 2)
Step-by-step explanation:
In a function, each value used in as an x-coordinate can be used only once.
Values already used as x-coordinates: -3, 8, 0, -5
The answer cannot have -3, 8, 0, or 5 as an x-coordinate.
The only choice without one of those four values as an x-coordinate is (1, 2).
Answer: B. (1, 2)
Answer:
B

-5 is already used
-3 is already being used
0 is already being used
