Find the surface area and volume. show your work.
9514 1404 393
Answer:
area = 211 +7√205 ≈ 311.22 square unitsvolume = 273 cubic unitsStep-by-step explanation:
Surface area
The length of the hypotenuse of the front facing triangle is given by the Pythagorean theorem:
d^2 = 13^2 +6^2 = 169 +36 = 205
d = √205
So, the perimeter of that triangle is ...
P = 13 +6 +√205 = 19 +√205
The total area of the rectangular faces of this triangular prism is then ...
rectangular face area = (base perimeter)·(prism height)
= (19 +√205)(7) = 133 +7√205
The area of the two triangular faces will be ...
triangular face total area = 2·(triangle area) = 2(1/2)(6)(13) = 78
Then the total surface area is ...
total surface area = rectangular face area + triangular face total area
total surface area = (133 +7√205) +78
surface area = 211 +7√205 ≈ 311.22 . . . . square units
__
Volume
The volume is the product of the area of the triangular base and the height of the prism.
V = Bh
V = (39)(7)
volume = 273 . . . . cubic units

The exponential functions are plotted on the graph and solved
1) y = 3ˣ = b)
2) y = 3⁻ˣ = a)
3) y = -3ˣ = c)
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
a)
y = 3ˣ
Now , the exponential function is plotted on the graph and is represented by the line b
b)
y = 3⁻ˣ
Now , the exponential function is plotted on the graph and is represented by the line a
c)
y = -3ˣ
Now , the exponential function is plotted on the graph and is represented by the line c

Step-by-step explanation:
A major airline knows that about 2 percent of passengers do not manage to show up for their flight. Consider a small aircraft having 50 seats, and suppose that an airline sells precisely 50 tickets for a specific flight. Assuming that all passsengers are independent and have the same probability of not showing up, compute the probability that
Answer:
a. The probability that the aircraft is fully occupied = 0.3642
b. The probability that between 1 and 5 (including 1 and 5) passengers do not show up is = 0.6354
Step-by-step explanation:
From the given information:
We are to compute the probability that:
a. The aircraft is fully occupied( i.e. all the passengers show up)
b. Between 1 and 5 (including 1 and 5) passengers do not show up
Given that:
Percentage of passengers that do not show up = 2% = 0.02
And the population of the passengers = 50; since 50 tickets are being sold for a specific flight.
Let assume X be the random variable that follows a binomial distribution, thus, the number of passengers from the aircraft with 50 passengers can be represented as:
[tex]X \sim Bin (n = 50, p =0.02)[/tex]
Thus;
The probability that the aircraft is fully occupied i.e. all the passengers show up is:
[tex]= (1 - 0.02)^{50}[/tex]
= 0.98⁵⁰
= 0.3642
Hence, The probability that the aircraft is fully occupied = 0.3642
b. The probability that between 1 and 5 (including 1 and 5) passengers do not show up is:
= P(X = 1) + P(X =2) + P(X = 3) + P(X = 4) + P(X = 5)
= [tex]=(^{50}_1) 0.02(1-0.02)^{50-1} +(^{50}_2) 0.02(1-0.02)^{50-2} + (^{50}_3) 0.02(1-0.02)^{50-3} + ... + (^{50}_5) 0.02(1-0.02)^{50-5}[/tex]
[tex]=(^{50}_1) 0.02(0.98)^{49} +(^{50}_2) 0.02(0.98)^{48} + (^{50}_3) 0.02(0.98)^{47} + ... + (^{50}_5) 0.02(0.98)^{45}[/tex]
= 0.6354
Hence, The probability that between 1 and 5 (including 1 and 5) passengers do not show up is = 0.6354
The Education Foundation hosted an annual fundraising dinner. There were 24 dinner tables with 8 chairs at each table. Each dinner ticket cost $12.50. If of the dinner tables were full, how much money was raised from the dinner ticket sales?
$225
⊝
$1,800
⊝
$2,400
⊝
$3,200
Answer:
2,400
Step-by-step explanation:
24 times 8 equals 192, 192 times 12.50 equals 2,400. If this does not help, sorry.
The amount raised is $2400.
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
There were 24 tables with 8 chairs at each table.
Total chairs.
= 24 x 8
= 192 chairs
Each dinner ticket cost $12.50.
And all the dinner tables were full.
So,
Total amount raised.
= 96 x 12.50
= 2400
Therefore,
The amount raised is $2400.

Step-by-step explanation:
the reason for this is because the total area for the triangle is 17 cm
and from whats shown on the rectangle it has only 12 so far so that means the w equals 2 1/2 because 12 + 2 1/2 + 2 1/2 = 17 so therefor the answer is 2 1/2cm
