Which does the P stand for in the surface area of prisms formula?
Perimeter of the base
Perimeter of the bottom face
Perimeter of the side
Perimeter of the posterior
Answer:
A
Step-by-step explanation:
perimeter of the base...
In the surface area formula for prisms, the letter "P" stands for "Perimeter of the base."
The surface area of a prism is calculated by adding the areas of all its faces. For a prism, the bases are typically parallel polygons, and the other faces are parallelograms connecting the corresponding vertices of the bases.
To find the area of the base, we need to consider its shape and dimensions. The perimeter of the base is the total length of all its sides. Therefore, when calculating the surface area of a prism, we need to determine the perimeter of the base and multiply it by the height of the prism.
By multiplying the perimeter of the base by the height, we obtain the lateral area of the prism. Adding the areas of the two bases to the lateral area gives us the total surface area of the prism.
So, in the surface area formula for prisms, the "P" represents the "Perimeter of the base."

9514 1404 393
Answer:
316.7 ft³
Step-by-step explanation:
The formula for the volume of a cone is ...
V = 1/3πr²h
Here, the radius (r) is half the diameter, so is 7.7 ft. Then the volume is ...
V = 1/3π(7.7 ft)²(5.1 ft) = 100.793π ft³ ≈ 316.6505 ft³
The volume of the cone is about 316.7 cubic feet.
_____
If you use the inappropriate value 3.14 for π, your answer will be 316.5 ft³.
A cylindrical soup can has a radius of 1.1 in. and is 5.4 in. tall. Find the volume of the can and round to the nearest tenths if necessary
Answer:
[tex]V=20.52\ in^3[/tex]
Step-by-step explanation:
Given that,
The radius and the height of the cylindrical soup can are 1.1 inch and 5.4 inch.
We need to find the volume of the can.
The formula for the volume of the can is given by :
[tex]V=\pi r^2 h\\\\V=\pi \times (1.1)^2 \times 5.4\\\\V=20.52\ in^3[/tex]
So, the volume of the can is equal to [tex]20.52\ in^3[/tex].
What is the maximum value and at what point
9514 1404 393
Answer:
maximum z: 43point: (x, y) = (25/7, 9)Step-by-step explanation:
In the attached, we have graphed the inequalities and the objective function line. As we might surmise by looking at the constraints,* the maximum occurs at the intersection of y=9 and 7x-y = 16, where (x, y) = (25/7, 9).
The maximum value of z is 7(25/7) +2(9) = 25 +18 = 43.
__
The graph shows all inequalities reversed. This has the effect of making the solution space white, rather than buried under 4 levels of shading. As we expect with most "maximize" problems, the feasible region vertex farthest from the origin is the one of interest.
_____
* The only upper bound on y is y ≤ 9. The only upper bound on x is 7x-y≤16. When we're maximizing some objective function with positive coefficients on the variables, these will be the boundaries of interest.
The perimeter of this triangular plot of land can be represented by the expression 3x2 + 10x + 20.
6x + 11
2x2 + 9
Write a polynomial that represents the measure of the third side of the plot of land.
Answer:
x^2+4x
Step-by-step explanation:
(3x^2+10x+20)-(6x+11) = 3x^2+4x+9
(3x^2+4x+9)-(2x^2+9) = x^2+4x
The polynomial that represents the measure of the third side of the plot of land is x² + 4x.
What is Perimeter?Perimeter of a straight sided figures or objects is the total length of it's boundary.
Given two sides of a triangular plot of land.
6x + 11
2x² + 9
Perimeter = 3x² + 10x + 20
Perimeter of a triangle = Sum of the three sides
Let A represents the third side.
6x + 11 + 2x² + 9 + A = 3x² + 10x + 20
2x² + 6x + 20 + A = 3x² + 10x + 20
A = 3x² + 10x + 20 - (2x² + 6x + 20)
A = x² + 4x
Hence the measure of the third side is x² + 4x.

After 40 attempts at drawing two marbles from the bag, there were three instances where a blue marble then a yellow marble was pulled. What is the experimental probability of pulling a blue marble and then a yellow marble? 0.0556 0.0750 0.0167 0.0333
Answer:
0.0750 I took the test
The experimental probability of pulling a blue marble and then a yellow marble is 0.075 or 7.5%, which is closest to answer option B.
What is probability?Probability is a statistical term that describes the possibility that something will occur.
Since there is only one blue marble in the bag, the likelihood of getting a blue marble on the first draw is 1/6.
After the blue marble is replaced, the probability of drawing a yellow marble on the second draw is 2/6, since there are now 2 yellow marbles out of a total of 6 marbles in the bag.
The probability of sketching a blue marble and subsequently a yellow marble in the same attempt is:
P(blue then yellow) = P(blue) x P(yellow | blue)
P(blue then yellow) = (1/6) x (2/6)
P(blue then yellow) = 1/18
Since the marbles are replaced after each draw, the probability of drawing a blue marble and then a yellow marble is independent of one attempt to the next.
The experimental probability of pulling a blue marble and then a yellow marble in 40 attempts can be calculated by dividing the number of times it occurred by the total number of attempts:
Experimental probability = number of times blue then yellow was pulled / total number of attempts
Experimental probability = 3 / 40
Experimental probability = 0.075
Therefore, the experimental probability of pulling a blue marble and then a yellow marble is 0.075 or 7.5%.

A lifeguard is standing beside the lifeguard chair on a beach.The lifeguard is 76 inches tall and casts a shadow that is 48 inches long.The chair casts a shadow that is 72 inches long.How y'all is the lifeguard chair?
9514 1404 393
Answer:
114 inches, or 9 ft 6 inches
Step-by-step explanation:
The chair's shadow is 72/48 = 1.5 times as long as the lifeguard's shadow. Since shadow length is presumed proportional to height, we expect the lifeguard chair to be 1.5 times as tall as the lifeguard.
1.5(76 in) = 114 in = 9 ft 6 in . . . height of lifeguard chair
A cup of coffee cost $2.50. If the total cost is $22.50, then how many cups of coffee were purchased?
a. Write an equation
b. What is the constant of proportionality?
An equation is formed of two equal expressions. The constant of proportionality between the number of cups of coffee and the total bill amount is 2.50.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that a cup of coffee cost $2.50. Now, if the total cost of coffees is $22.50, then the number of cups of coffee that was purchased is,
Number of cups of coffee = Total bill amount / Cost of a coffee
Number of cups of coffee = $22.50 / $2..50
Number of cups of coffee = 9
A.) An equation for the total bill amount, y and total number of cups of coffee, x can be written as,
Total bill amount = Cost of a coffee × Number of cups of coffee
y = 2.50 × x
y = 2.50x

Answer:
9
Step-by-step explanation:
We're using the Pythagorean theorem here since it's a right triangle.
a^2 (side) + b^2 (side) = c^2 (hypotenuse)
12 = a
x = b
15 = c
12^2 + b^2 = 15^2
144 + b^2 = 225
- 144 - 144 (subtracting 144 from both sides to isolate b)
b^2 = 81
[tex]\sqrt{b^2} = \sqrt{81}[/tex] (getting rid of the exponent by squaring both sides)
b = 9

Answer:
its 20 inches
Step-by-step explanation:
Answer:
26 inches
Step-by-step explanation:
To the nearest inch, the diameter of the tire is 26 inches.
The bike traveled 136 feet in 20 revolutions. First we want to convert this to inches.
136 ft * 12 in/ft = 1632 inches.
Next we find how many inches it travels in 1 revolution:
1632/20 = 81.6 inches
The distance around the tire is called the circumference, and the formula for circumference is
C=πd
Our circumference is 81.6 and π is 3.14:
81.6 = 3.14d
Divide both sides by 3.14:
81.6/3.14 = 3.14d/3.14
26 = d
