The net of a right rectangular pyramid is shown.
What is the surface area of the right rectangular pyramid?
Answers
The surface area of the right rectangular pyramid is 96 sq. ft.
What is the net's surface area?A net pattern is produced when the surface of a three-dimensional figure or solid is spread out flat and each aspect of the shape is visible. The net may then be used to calculate the solid's surface area.
The surface area of the net is calculated by adding the areas of all of its faces. The net's surface area is calculated by summing the surface areas of all its forms.
The surface area of the given net is calculated by adding the area of all the individual shapes in the net.
For the given net the area of the triangle with h= 5 ft and b = 8 ft is:
A1 = 1/2(8)(5)
A1 = 20 sq. ft.
There are two such triangles thus:
A1 = 2(20) = 40 sq. ft
For the triangle with h = 6 ft and b = 4 ft:
A2 = 1/2)(4)(6)
A2 = 12
There are two such triangles thus:
A2 = 2(12) = 24 sq. ft
The area of the rectangle in the center is:
A3 = (8)(4)
A3 = 32 sq. ft
The total surface area of the net is:
A = A1 + A2 + A3
A = 40 + 24 + 32
A = 96 sq. ft.
Hence, the surface area of the right rectangular pyramid is 96 sq. ft.

Answers
Answer:
P+n<20
Step-by-step explanation:
The given situation can be expressed as an inequality as p + n ≤ 20.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
Ethan has p pennies and n nickels.
Number of pennies = p
Number of nickels = n
Total number of coins is no more than 20.
This means that the combined total of pennies and nickels does not exceed 20.
sum of p and n is less than or equal to 20.
p + n ≤ 20
Hence the required inequality expression is p + n ≤ 20.

What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
1) By using the angle sum property of triangle
∠A+58°+61°=180°
∠A+119°=180°
∠A=61°
2) ∠B+50°=180° (Adjacent angles)
∠B=130°
3) ∠A=∠C (Angles of same segment)
∠C=58°
4) ∠D=50° (Vertically opposite angles)
5) 111°+90°+75°+∠E=360° (Sum of interior angles of quadrilateral)
∠E= 84°
6) 111°+84°+130°+130°+x=540° (Sum of interior angles of pentagon)
∠F=x=85°
∠F= 85°
7) 70°+50°+y=180° (angle sum property of triangle)
y=60°

Step-by-step explanation:
27) If x represents the number of boxes, and there are 12 cookies in each box, multiplying 12 by x results in the total number of cookies Kendal bought. However, she kept 2 boxes for herself, which is the same as 2(12) = 24 cookies. Kendal ended up with 60 cookies at the party, so subtracting 24 cookies from the total number of cookies (12x) equals 60 cookies.

In discrete mathematics, a truth table is a table that lists all possible combinations of truth values for a given set of logical variables and shows the resulting truth values of a compound proposition.
In discrete mathematics, a truth table is a table that lists all possible combinations of truth values (usually either true or false) for a given set of logical variables and shows the resulting truth values of a compound proposition (a logical expression formed by combining the variables using logical operators such as AND, OR, and NOT). Each row of the truth table represents one possible combination of truth values, and the columns represent the variables and the various intermediate steps of the logical calculation. Truth tables are often used to determine the truth values of complex propositions and to test the validity of logical arguments.

you lease a car vauled at 23495 for 3 years
at 429.95/month
Answers
The amount of interest paid over the 3-year lease is $4,643.64 for a car.
What is a monthly payment?A monthly payment is a payment made every month to disburse loans or advances.
First, we need to calculate the total amount paid over the 3-year lease.
The monthly payment is $429.95, and there are 36 months in the lease, so:
Total lease payments = 36 x $429.95 = $15,478.20
The down payment of $500 is separate from the lease payments, so we don't include it in this calculation.
Next, we need to calculate the interest paid over the 3-year lease. We are told that interest is 30% of the monthly payment, so:
Monthly interest = 30% of $429.95 = $128.99
To find the total interest paid over the 3-year lease, we can simply multiply the monthly interest by the number of months in the lease:
Total interest paid = 36 x $128.99 = $4,643.64
Therefore, the amount of interest paid over the 3-year lease is $4,643.64.

what is 8.75 as a fraction?
Answers
The number 8.75 is equivalent to the fraction 35/4 in its simplest form.
To convert 8.75 to a fraction, we can write it as a fraction with a denominator of 1. We then multiply both the numerator and denominator by 100 to get rid of the decimal point. This gives us:
8.75 = 8.75/1
= 875/100
Next, we want to get rid of the decimal point, which we can do by multiplying both the numerator and denominator by a power of 10 that moves the decimal point of the numerator to the right until it disappears. In this case, we can multiply both the numerator and denominator by 100, which gives us:
8.75/1 x 100/100 = 875/100
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 25. This gives us:
875/100 = (875/25) / (100/25) = 35/4
Therefore, we conclude that 8.75 is equivalent to the fraction 35/4 in its simplest form.

Using trigonometric identities to simplify the following expression:
tan(θ)cot(θ)
Answers
Answer:
Step-by-step explanation:
The expression tan(θ)cot(θ) can be simplified using the trigonometric identity:
tan(θ) = sin(θ) / cos(θ)
cot(θ) = cos(θ) / sin(θ)
So,
tan(θ)cot(θ) = (sin(θ) / cos(θ)) x (cos(θ) / sin(θ))
= sin(θ) x cos(θ) / (cos(θ) x sin(θ))
= sin^2(θ) / sin^2(θ)
= 1
Therefore, tan(θ)cot(θ) = 1.
A boat traveled 165 miles each way downstream and back. The trip downstream took 11 hours.
The trip back took 15 hours. What is the speed of the boat in still water? What is the speed of
the current?
Answers
The speed of the boat in still water is 20.625 km/hr. and the speed of the current is 66 km/hr.
What is the relation of speed and distance?The speed formula is speed = distance / time.
Consider x= speed of current and y = speed of still water
The speed of the boat in still water can be calculated by dividing the total distance traveled by the total time taken;
(165 km x 2 = 330 km)
(5 hours + 11 hours = 16 hours).
Therefore, the speed of the boat in still water
330 km/16 hours = 20.625 km/hr.
The speed of the current can be calculated by dividing the total distance traveled by the total time taken for the downstream trip ;
(165 km x 2 = 330 km)
(5 hours).
Therefore, the speed of the current = 330 km/5 hours = 66 km/hr.
Hence,
speed of still water = 20.625 km/hr.
speed of current = 66 km/hr

Marco's charges an additional fee for toppings, but all toppings cost the same. Kevin got pepperoni, banana peppers, and black olives on his pizza for a cost of $15.74. Brian ordered mushrooms and eggplant on his pizza and paid $14.49. Using this information, write an equation for the cost of a pizza, C, as a function of the toppings, t, ordered.
Answers
Answer: Let's use x to represent the cost of each topping. Then, the cost of a pizza with t toppings can be expressed as:
C = x * t + 15
We know that Kevin's pizza with 3 toppings cost $15.74, so we can write an equation using this information:
15.74 = 3x + 15
Solving for x, we get:
x = (15.74 - 15) / 3 = 0.74
So, each topping costs $0.74. Now we can use the information about Brian's pizza to check our answer:
14.49 = 2x + 15
Substituting x = 0.74, we get:
14.49 = 2 * 0.74 + 15
Which simplifies to:
14.49 = 1.48 + 15
This confirms that x = 0.74 is the correct cost for each topping. Therefore, the equation for the cost of a pizza as a function of the toppings ordered is:
C = 0.74t + 15
