Edith wants to make a paperweight at pottery class. She wants the paperweight to have a pyramid-like shape with a base area of 120120120 square centimeters, and she wants it to weigh 400400400 grams. The density of the clay she is using is 1.61.61, point, 6 grams per cubic centimeter.
What should be the height of the paperweight?
Answer:
Step-by-step explanation:
We would determine the volume of the
pyramid-like paperweight. Formula for volume is expressed as
Volume = mass/density
From the information given,
mass = 400g
Density = 1.61g/cm³
Volume = 400/1.61 = 248.45cm³
The formula for determining the volume of a pyramid us expressed as
Volume = 1/3 × base area × height
From the information given,
Base area = 120 cm²
Volume = 248.45cm³
Therefore,
248.45 = 1/3 × 120 × height
248.45 = 40 × height
height = 248.45/40 = 6.2 cm

Answer:
13 cm
Step-by-step explanation:
To find the answer, you can use the formula to calculate the volume of a cone and isolate the height:
V= πr^2[tex]\frac{h}{3}[/tex]
V= volume= 218 cubic centimeters
π= 3.14
r= radius= 4 cm
h=height
218= 3.14*4^2*[tex]\frac{h}{3}[/tex]
218*3=3.14*16*h
654=50.24*h
h=654/50.24
h=13
According to this, the height of the container is 13 cm.

Adrian makes $36.50 per day plus tips. His average tip is 17% of the total amount of money customers spend. Which equation could be used to determine x, the total amount of money customers would need to spend for Adrian to earn a daily income of $150? A. 150 = 36.50 + 17x B. 150 = 0.17 + 36.50x C. 150 = x(17 + 36.50) D. 150 = 36.50 + 0.17x
Answer:
For this case we know that the fixed cost is $36.50 and the variable cost is 17% of the total amount of money customers spend, let's asusme that this variable is x. And we can create a model like this one:
[tex] y = mx +b[/tex]
Where y represent the income and x the the total amount of money customers would need to spend. For this case the value for b = 36.50 and the slope m would be 0.17 since if we convert the % into a fraction we got 0.17. So then the best option is:
[tex] 150 = 36.5 +0.17x[/tex]
D. 150 = 36.50 + 0.17x
Step-by-step explanation:
For this case we know that the fixed cost is $36.50 and the variable cost is 17% of the total amount of money customers spend, let's asusme that this variable is x. And we can create a model like this one:

An urn contains 3 red and 7 black balls. Players and withdraw balls from the urn consecutively until a red ball is selected. Find the probability that selects the red ball. ( draws the first ball, then and so on. There is no replacement of the balls drawn.)
Correct question:
An urn contains 3 red and 7 black balls. Players A and B withdraw balls from the urn consecutively until a red ball is selected. Find the probability that A selects the red ball. (A draws the first ball, then B, and so on. There is no replacement of the balls drawn).
Answer:
The probability that A selects the red ball is 58.33 %
Step-by-step explanation:
A selects the red ball if the first red ball is drawn 1st, 3rd, 5th or 7th
1st selection: 9C2
3rd selection: 7C2
5th selection: 5C2
7th selection: 3C2
9C2 = (9!) / (7!2!) = 36
7C2 = (7!) / (5!2!) = 21
5C2 = (5!) / (3!2!) = 10
3C2 = (3!) / (2!) = 3
sum of all the possible events = 36 + 21 + 10 + 3 = 70
Total possible outcome of selecting the red ball = 10C3
10C3 = (10!) / (7!3!)
= 120
The probability that A selects the red ball is sum of all the possible events divided by the total possible outcome.
P( A selects the red ball) = 70 / 120
= 0.5833
= 58.33 %

A construction company buys a bulldozer for $26,000. The company expects the useful life of the machine to be 12 years, at which time its value will have depreciated to $6000. The company uses the declining balances method for depreciation, so the annual depreciation rate r (in decimal form) is given by the formula r=1−(S/C)^1/n . In the formula, n is the useful life of the item (in years), S is the salvage value (in dollars), and C is the original cost (in dollars). What annual depreciation rate (in percent form) did the company use? Round your answer to the nearest tenth.
Answer:
11.5%
Step-by-step explanation:
Put the given numbers in the formula and do the arithmetic.
r = 1 - (6000/26000)^(1/12) = 1 -(3/13)^(1/12) ≈ 1 -0.88498 ≈ 11.5%
The company used a depreciation rate of 11.5%.

HDTV screens usually have a width-to-heigh ratio of 16:9. Which screen dimensions are in the same proportion?
Answer:
4: 3
Step-by-step explanation:
In this case, we have that there is a relationship between width and height, which is 16: 9, which means that any screen that has the same ratio would be an identical screen.
How would we do this? it must either be raised to a power or rationalized on both sides of the ratio.
If we raise to a power, it would give very large dimensions for an HDTV, therefore, it is best to remove the square root on both sides, since it has more common values for a TV.
[tex]\sqrt{16} :\sqrt{9}[/tex]
4: 3
Therefore, a 4: 3 screen is a good choice for an HDTV with the same ratio.

A wire with a length of 100 cm is cut into three parts. The length of wire of the first and second parts are the same. The length of the third part of the wire exceeds the sum of the first two parts by 4 cm. Calculate the length of each part.
The first two pieces are the same, let each of those equal x, so you have x + x = 2x
The 3rd piece is the sum of the first two + 4, so this would be 2x + 4
Now you have 2x + 2x + 4 = 100 cm
Combine like terms:
4x +4 = 100
Subtract 4 from both sides
4x = 96
Divide both sides by 4
X = 24
First piece is 24 cm
Second piece is 24 cm
Third piece is 52 cm

The height of a saw tooth in inches after time in seconds is represented by the function y = 0.4sin (15x + 1.5) - 0.2 for t > 0. Without graphing the function, determine the maximum height that the saw tooth reaches.
Answer:
0.2 Inches
Step-by-step explanation:
Given the height of the saw tooth represented by the function
[tex]y = 0.4sin (15x + 1.5) - 0.2$ for $t > 0.[/tex]
Comparing with the general form of a trigonometric equation
[tex]y = A sin(B(x + C)) + D[/tex]
Where:
A =AmplitudePeriod =[tex]2\pi/B[/tex]C=Phase Shift D=Vertical ShiftAmplitude, A=0.4
Vertical Shift (Midline),D = - 0.2
The maximum and minimum height of the sinusoidal function is given by:
[Min, Max]=[D-A, D+A]
=[-0.2-0.4, -0.2+0.4]
=[-0.6,0,2]
The maximum height that the sawtooth reaches is 0.2 inches.
