Total cost of pay for the lunch will be $96.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The cost of lunch = $75
Sales tax = 8%
Tip = 20%
Now,
The cost on sales tax = 8% of $75
= 8/100 x 75
= $6
Thus, The cost on sales tax = $6
And, The cost for tip = 20% of $75
= 20/100 x 75
= $15
Thus, The cost for tip = $15
So, Total cost to pay for lunch = $75 + $6 + $15
= $96
Thus, Total cost of pay for the lunch will be $96.

Calculate the lower bound and upper bound for Helen's value of .
Give your answers correct to 3 decimal places.
Answer:
lower bound: 2.996
upper bound: 3.244
Step-by-step explanation:
The value that Helen wants to use is Pi = C/D. The lower bound value is 3.065, and the upper bound for Helen's value is 3.165.
What is circumference?The circumference is the perimeter of the circle.
Given, the circumference, C, at 405 mm to three significant numbers.
She correctly estimates the diameter, d, to be 130 mm to two significant numbers.
Helen wants to find the value of Pi using the formula pi=C/D
We have, the circumference of the circle = C = 405 mm
The diameter of the circle = d = 130 mm
Pi = C/D
= 405 mm / 130 mm
= 405 / 130
= 3.115
3.115, measured to the nearest 0.1.
The degree of accuracy is nearest 0.1.
0.1/2 = 0.05
Upper bound = 3.115 + 0.05 = 3.165
Lower bound = 3.115 - 0.05 = 3.065
Therefore, the lower bound and upper bound for Helen's value are 3.165, and 3.065.

Which measurement is equivalent to 84 inches?
A.8 feet
B. 1 yard, 2 feet, 24 inches
C. 7 feet, 4 inches
D. 4 feet, 40 inches
Answer: A
Step-by-step explanation:
Answer: B. 1 yard, 2 feet, 24 inches
Step-by-step explanation: 1 yard is 36 inches. Each feet is 12 inches, but there are 2 feet so 12 times 2 is 24 inches. And the last is just 24 inches. So, 36 + 24 + 24 = 84 inches

The equation of a circle is x2 + y2 - 12y + 20 = 0
What are the coordinates of the center and the length of the radius of the circle?
Answer:
Center: (0, 6); radius = 4
Step-by-step explanation:
x^2 + y^2 - 12y + 20 = 0
We must complete the square in y.
x^2 + y^2 - 12y = -20
x^2 + y^2 - 12y + 36 = -20 + 36
x^2 + (y - 6)^2 = 16
(x - 0)^2 + (y - 6)^2 = 4^2
Center: (0, 6); radius = 4

Group of answer choices
$22,366.96
$12,395.17
$22,905.95
$12,920.84
Answer:
$10,857.8
Step-by-step explanation:
Brad wants to have $17000 available to buy a car in 5 years. How much should he deposit now at 9% compounded monthly to reach that goal?
A = p(1 + r/n)^nt
P = A / (1 + r/n)^nt
P = 17000 / (1 + 0.09/12)^(12*5)
= 17,0000 / (1 + 0.0075)^60
= 17,000 / (1.0075)^60
= 17,000 / 1.5657
= 10,857.8
P = $10,857.8
100 POINTS!!! SHOW ALL WORK PLZ!!! Tarah bought 42 shares of a company’s stock for $16.45 / share. She pays a broker a commission of $7 to buy and
sell stock. After one year, Tarah sold all her shares, when they were worth $20.64 / share.
How much did it cost Tarah to buy the stock? Show your work.
What was Tarah’s net gain or loss? Show your work.
What was Tarah’s annual rate of return? Show your work, make answer a % and then round to tenths place.
Answer:
`a) $697.90
b) $161.98 gain
c) 23.2096% annual return rate
Step-by-step explanation:
a) $16.45 for one share. 42 shares will cost 16.45 x 42 = $690.90
As she used a broker and paid $7, the total cost for Tarah would be $697.90
b) After the investment, Tarah's gain is $20.64 per stock and she had bought 42. So the total income would be 20.64 x 42 = $866.88. However, she used a broker to sell the stocks as well, so the total gain would only be 859.88.
Overall, the cost was -697.90+859.88 = 161.98 net gain.
c) The rate of return would be the percentage of the original price of stocks that is equal to the net gain. What we are trying to find here is:
What percentage of 697.90 is 161.98?
We can find this percentage by doing a simple division (161.98/697.90) which gives us an answer of 0.232096
In percentages, multiply this decimal by 100 to get a 23.2096% annual return.

Triangle STU is rotated 270 clockwise about the origin to create triangle S'T'U'. If point U of triangle STU is a (a,b), which algebraic representation best describes point U' of triangle S'T'U'?
Answer:
(b, -a)
Step-by-step explanation:
First note that the rule for a rotation by 270° about the origin is (x,y)→(y,−x)
Note that the coordinates were swapped and the x coordinates negated. Similarly;
Given the coordinate of the point U as (a, b), if the triangle is rotated 270degrees clockwise, the resulting coordinate will be (b, -a)

Step-by-step explanation:
Use the Pythagorean Theorem.
c^2 = a^2 + b^2
a = 10
b = 24
c = ?
c^2 = 10^2 + 24^2
c^2 = 100 + 576

Answer:
6 * 2/3 = 12/3 = 4
Step-by-step explanation.
you can think about it like this: 6 * 1/3 * 2
1/3 of 6 is 2 because 2 * 3 is 6
2 * 2 is 4, therefore the correct answer is 4
remember doing 6 * 2/3 is the same as doing 6/1 * 2/3 if that helps
A wooden board is leaning against a wall. The base of the board is 10 feet from the base of the wall. The base of the board forms a 35° angle with the ground.
What is the length of the wooden board?
Round your answer to nearest tenth.
Answer:
The length of the wooden board is about 12.2 feet.
Step-by-step explanation:
Please refer to the diagram attached below.
The base of the board forms a 35° degree angle with the ground.
And we want to find the length of the wooden board.
Since we are given an angle and its adjacent length and we want to find the hypotenuse, we can use the cosine ratio:
[tex]\displaystyle \cos(\theta^\circ)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]
The adjacent side is the distance from the wall to the board, which is 10 feet.
And the angle made is 35°.
The hypotenuse is the length of the wooden board. Therefore:
[tex]\displaystyle \cos(35)=\frac{10}{\ell}[/tex]
Solve for the length. Cross-multiply:
[tex]\displaystyle 10=\ell \cos(35)[/tex]
Therefore:
[tex]\displaystyle \ell=\frac{10}{\cos(35)}\approx12.2[/tex]
The length of the wooden board is about 12.2 feet.
if a translation has a coordinate notation of (x,y) --> (x+1,y-3) then what is the image of (4,-4)
Answer:
(5, - 7 )
Step-by-step explanation:
A translation rule of
(x, y ) → (x + 1, y - 3 )
means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate, that is
(4, - 4 ) → (4 + 1, - 4 - 3 ) → (5, - 7 )
The base of an isosceles triangle is 16 cm long. The equal sides are each 22 cm long. Find the height of the triangle.
Given:
The base of an isosceles triangle is 16 cm long.
The equal sides are each 22 cm long.
To find:
The height of the triangle.
Solution:
We know that the altitude of an isosceles triangle divides the base into two equal parts as shown in the below figure.
According to the Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Using Pythagoras theorem, we get
[tex]22^2=h^2+8^2[/tex]
[tex]484=h^2+64[/tex]
[tex]484-64=h^2[/tex]
[tex]420=h^2[/tex]
Taking square root on both sides, we get
[tex]\sqrt{420}=h[/tex] (Because side cannot be negative)
[tex]2\sqrt{105}=h[/tex]
Therefore, the height of the isosceles triangle is [tex]2\sqrt{105}[/tex] cm. Approximate height is 20.49 cm.

draw the line of reflection that reflect quadrilateral ABCD onto quadrilateral A'B'C'D
Answer:
-3 across the x
Step-by-step explanation:
negative 3 is in the middle of the two, both between point -1 and -5, and point 0 and -6.
When a shape is reflected, it must be reflected over a line. The line of reflection of quadrilateral ABCD onto quadrilateral A'B'C'D is [tex]y = -3[/tex]
From the given graph, we have the following observations
ABCD was flipped over to form A'B'C'D'The line of reflection is between both shapesUsing points C and C' as reference;
We have:
[tex]C = (-3,-1)[/tex]
[tex]C' = (-3,-5)[/tex]
Notice that both points have the same x-coordinate
This means that the line of reflection is parallel to the x-axis, and it passes through the y-axis.
The point at which it passes through the y-axis is calculated using mid-point formula.
So, we have:
[tex]y = \frac{y_1 + y_2}{2}[/tex]
[tex]y = \frac{-1-5}{2}[/tex]
[tex]y = \frac{-6}{2}[/tex]
[tex]y = -3[/tex]
Hence, the line of reflection is [tex]y = -3[/tex]
