A solid silver paperweight in the form of a square pyramid is shown below. If silver costs $0.12 per cubic centimeter, how much would it cost to manufacture 6 paperweights?
Answers
Answer:
It would cost $232.32, this answer is rounded.
Step-by-step explanation:
The formula for the volume of a square pyramid is:
[tex]V=a^2\frac{h}{3}[/tex]
So its just:
[tex]8.8^2\frac{12.5}{3} = 322.67 cm^3[/tex]
Then you just multiply the volume by the cost per cubic centimetre:
[tex]322.67cm^3*$0.12=$38.704[/tex]
After just multiply the cost of one by how many you want, which is 6:
[tex]38/704*6=232.32[/tex]
The cost to manufacture 6 paper weight is $232.32
Volume of a square pyramid:v = 1 /3 b²hwhere
b = base
h = height
Therefore,
v = 1 / 3 × 8.8² × 12.5
v = 1 / 3 × 77.44 × 12.5
v = 968 / 3
v = 322.666666667 cm³
1 cm³ = $0.12
322.67 cm³ = ?
cost of a paperweight = 322.67 × 0.12 = $38.72
Therefore,
1 paper weight = $38.72
6 paper weight = ?
cross multiply
cost of 6 paper weight = 6 × 38.72
cost of 6 paper weight = $232.32

Answers
Answer:
First option
Step-by-step explanation:
There is a mistake in the description of the first function.
On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).
Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:
Rate of change: (y2 - y1)/(x2 - x1)
Points of the 1st graph: (-4, 1), (0, 3).
Rate of change: (3- 1)/(0 - (-4)) = 1/2
Points of the 2nd graph: (-4, 1), (0, -3).
Rate of change: (-3 - 1)/(0 - (-4)) = -1
Points of the 3rd graph: (-4, 0), (0, 4).
Rate of change: (4 - 0)/(0 - (-4)) = 1
Points of the 4th graph: (-4, 0.25), (0, 4).
Rate of change: (4 - 0.25)/(0 - (-4)) = 0.9375

(12,3) (12,11) on the same x coordinate, 8 squares apart
8 × 5 = 40
The area of a rectangle with vertices at (7,3), (12,3), (12, 11), and (7,11) is 40 square unit.
What are Coordinates?A brace of figures called equals are used to detect a point or a form in a two- dimensional aeroplane . Thex-coordinate and the y- match are two figures that define a point's position on a 2D aeroplane .
We have vertices of rectangle as
vertices at (7,3), (12,3), (12, 11), and (7, 11).
Now, the coordinates (7,3) and (12,3) have the same y coordinate also the difference in x match is 5 places piecemeal.
and, (12,3) and (12,11) have the same x coordinate then the difference in y coordinate is 8 squares apart.
So, the Area of rectangle

When Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second . If Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number ?
Answers
Answer:
87% would be faster than 58 seconds
Step-by-step explanation:
Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second
[tex]\mu = 60[/tex]
Standard deviation =[tex]\sigma = 1[/tex]
We are supposed to find Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number i.eP(x<58)
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{58-60}{1}\\Z=-2[/tex]
Refer the z table for p value
P(x<58)=0.0228
Landon were to 38 practice trials
So, P(x<58)=[tex]38 \times 0.0228=0.8664[/tex]
So, 86.64% would be faster than 58 seconds
Hence 87% would be faster than 58 seconds

Step-by-step explanation:
There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number
To calculate the percentage change, we will follow the steps below:
First, we will find the difference(that is increase) between 144 and 346
Increase = New number - Original number
= 346 - 144
= 202
Next is to divide the increase which is 202 by the original number which is 144 and then multiply by 100
That is;
percentage change = increase ÷ original number × 100
=202 / 144 × 100
≈ 140 to the nearest whole number
percentage change ≈ 140 %
Let the equation C = 2.32 N + 34,180 represent the cost of raising a child, C, on an income, N.

$172,460
$173,380
$175,620
$176,980
Answers
Answer:
173,380
Step-by-step explanation:
just took the test and got it right
The expected cost of raising a child is $173,380.
Given,
C = 2.32 N + 34,180.
C represents the cost of raising a child.
N represents the income.
If the Murphy family has an annual income of $60,000.
We are to find the expected cost of raising a child using the given equation.
We have,
C = 2.32 N + 34,180________(A)
Now,
If the Murphy family has an annual income of $60,000.
N = $60,000___________(B)
Putting (B) in (A).
C = 2.32 x $60,000 + 34,180
C = 139,200 + 34,180
C = $173,380.
Thus the expected cost of raising a child is $173,380.
