How much, in total, did Noel spend to cash her three most recent paychecks?
Based on the amount that Noel cashed in each of her most recent paychecks, the amount she spent in total is $10.99.
How much did Noel spend?The bank directory shows that you are charged 1.99% of the amount being cashed as well as a check processing fee of $1.39.
The amount Noel spent is therefore:
= (1.99% x 100.53) + (1.99% x 119.38) + (1.99% x 122.52) + (1.39 x 3 checks)
= 2.00 + 2.38 + 2.44 + 4.17
= $10.99

A 60 cm high cylinder with 14 cm its diameter is cut vertically into two equal halves. what is the volume of a half part
The volume of the half part of a cylinder of 60 cm high and 14 cm in diameter is 1470π cm³.
Volume of a cylindervolume of a cylinder = πr²h
where
r = radiush = heightTherefore,
r = 14 / 2 = 7 cm
h = 60 cm
volume of the cylinder = π × 7² × 60
volume of the cylinder = π × 49 × 60

Trigonometry, how would I find the area of this triangle?
Answer:
Step-by-step explanation:
Area of triangle = 1/2 * base * height
Use the side of length 5.6cm as base, the height will be a perpendicular line from the base to the tip of the triangle.
From the right-angle triangle formed by the height and the side of length 3.9cm,
sin(56°45') = height / 3.9
height = 3.9*sin(56°45')
Substituting back into the area equation:
Area = 1/2*5.6*3.9*sin(56°45')
= 9.0cm^2
= 9cm^2
Use sine rule for Area
[tex]\\ \rm\rightarrowtail Area=\dfrac{1}{2}absinC[/tex]

What is the value of k?
Answer:
10°
Step-by-step explanation:
According remote interior angles, 4k + 5 + 6k + 10 = 115.
10k + 15 = 115
10k = 100
k = 10
Hope this helps :)
Have a nice day!
Answer:
k = 10°
Step-by-step explanation:
According to the exterior angle theorem, the exterior angle will be equal to the two opposite inside angles added together. It will look like the following, and we solve for k from there.
115° = (4k + 5)° + (6k + 10)°
115° = 4k° + 5° + 6k° + 10°
115° = 6k° + 4k° + 10° + 5°
115° = 10k° + 15°
100° = 10k°
10° = k
k = 10°

Find the area. What type of triangle is triangle ABC?
Answer:
Isosceles right triangles are half squares, and if the length of one side is 6cm, that is the length of the other side since both segments are equal. Take the formula to find the area of a square (base times height), apply the side measurement of the triangle (6cm) and divide it in half to find the area of half of it (therefore, finding the area of the isosceles triangle.) (6x6) / 26x6 = 3636 / 2 = 18 The area of the isosceles triangle is 18 square centimeters.

Help!!!!!!! v is a vector of magnitude 4 making an angle of 30° with the positive x-axis. find v in component form .
Since v is a vector of magnitude 4 and makes angle 30° with the positive x axis, vector v in component form is v = 2√3i + 2j
To find vector v in component form, we need to know what a vector is
What is a vector?A vector is a physical quantity that has both magnitude and direction.
Component of a vectorA vector can be resolved into perpendicular components along the x, y and z axis.
Components of vector vSince vector v has a magnitude of 4 making an angle of 30 with the positive x - axis, its x-component is V = (vcos30°)i
= (4cos30°)i
= (4 × √3/2)i
= 2√3i.
The y-component of v is V' = (vsin30°)j
= (4 × sin30°)j
= (4 × 1/2)j
= 2j
Vector v in component form
So, vector v in component form is v = V + V'
= 2√3i + 2j
So, since v is a vector of magnitude 4 and makes angle 30° with the positive x axis, vector v in component form is v = 2√3i + 2j

Step-by-step explanation:
We will set up a proportion. I will have the weight, in pounds, on the top (numerator) and the length, in inches, on the bottom (denominator).
[tex]\frac{12}{36} =\frac{x}{40}[/tex]
Cross-multiply:

x = 13 [tex]\frac{1}{3}[/tex] pounds
Answer:
Step-by-step explanation:
First find unit weight.
1 foot = 12 inches
3 ft = 3*12 = 36 inches
3ft 4 inches = 36 + 4 = 40inches

B. If the price is $30, how much revenue will the company earn?
A. The rule for the function r(x) is r(x)=
Answer:
Sorry let me try to understand the question
Step-by-step explanation:
The domain of the function r(x) is (0, 200).
The revenue earned when the price is $30 is $20400.
The rule for the function r(x) is x(800 - 4x).
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Demand:
d(x) = 800 - 4x
Price = x
Revenue = Price x demand
Revenue = r(x)
A)
The rule for r(x).
r(x) = x d(x) = x(800 - 4x)
The domain of r(x) is 0 < x < 200 i.e (0, 200).
B)
x = 30
r(x) = 30(800 - 4 x 30)
r(x) = 30(800 - 120) = 30 x 680 = 20400
C)
r(x) = x(800 - 4x)

Natoshia's den is 4 feet longer than it is wide. If the den's area is 320 square feet, what are the dimensions of the room?
Dimensions : 16 x 20
Let the width be xthen the length: x + 4 area of rectangle = Length * Widthsolving steps:
(x+4)(x) = 320x² + 4x = 320x² + 4x - 320 = 0x² +20x -16x -320 = 0x(x + 20) -16(x+20) = 0(x-16)(x+20) = 0x = 16, -20x = 16 [ As length or width can never be negative ]So we found Width = 16 feet
Length:
16 + 420 feetAnswer:
width = 16 ft
length = 20 ft
Step-by-step explanation:
Let width = x
If the length is 4 ft longer than the width, then
⇒ length = x + 4
Area of a rectangle = width × length
Given:
area = 320width = xlength = x + 4Substituting these values into the equation for the area of a rectangle and solving for x:
⇒ 320 = x(x + 4)
⇒ 320 = x² + 4x
⇒ x² + 4x - 320 = 0
⇒ (x - 16)(x + 20) = 0
⇒ x = 16, -20
As distance is positive, then x = 16 only.
Therefore, width = 16 ft and length = 20 ft

What is the height of the object after 0.60.60, point, 6 seconds? Round your answer, if necessary, to two decimal places.
The object attached to a string illustrates a sinusoidal trigonometric function
The trigonometric function is H(t) = 5sin(π/2(t-0.2))-20, and the object's height after 0.6 seconds is -17.06 cm
How to determine the trigonometry function model?The trigonometry model of the object is a sine function represented by:
H(t) = Asin(B(t - c)) + D
The maximum height is 5 cm.
So, we have:
Amplitude, A = 5
The average height is - 20 cm.
So, we have
Vertical shift, D = -20
Its first average height is at t = 0.2.
So, we have:
Horizontal shift, C = 0.2
The period B is then calculated as:
B = π/t
The object reaches the maximum height every 2 seconds.
So, we have:
B = π/2
Substitute these values in H(t) = Asin(B(t - c)) + D
H(t) = 5sin(π/2(t-0.2))-20
Hence, the trigonometric function is H(t) = 5sin(π/2(t-0.2))-20
The height of the object after 0.6 secondsSubstitute 0.6 for t in H(t)
H(0.6) = 5sin(π/2(0.6-0.2))-20
Evaluate
H(0.6) = -17.06
Hence, the object's height after 0.6 seconds is -17.06 cm
