A pyramid has a square base with sides that measure 10cm and a height of 14cm. What is the slant height of the pyramid?
A)17.2 cm
B)14.9 cm
C)13.2 cm
D)12.1 cm
Answers
The solution is, the slant height of the pyramid is 14.9 meters.
What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
here, we have,
we know that,
The slant height is the height of a triangle making up the base of the pyramid.
We can imagine a right triangle with one leg being a vertical line from the peak of the pyramid going down to the center of the base, and the other leg going from the center of the base to the center of one edge of the base.
And finally, the hypotenuse will join the ends of those 2 lines together and will also be the slant height of the pyramid.
Then we can easily use the Pythagorean theorem to determine the slant height.
So, S = sqrt((10/2)^2 + 14^2)
S = sqrt(5^2 + 14^2)
S = sqrt(25 + 196)
S = sqrt(221)
S = 14.9
So the slant height of the specified pyramid is 14.9 meters.

4 painters can paint a room in 6 hours how long will it take 3 painters to paint the same room
Answers
Answer:
the answer is that it will take 3 panters 3.5 hours to pant that room
Step-by-step explanation:
The number of hours taken by the painter to paint the room will be 4.5 hours .
Given,
4 painters can paint a room in 6 hours .
Now according to the method of unitary,
If 4 painters can paint the room in 6 hours ,
Then
1 painter will paint the room in
6/4 hours
= 3/2 hours .
Now the number of painters are 3
So if 1 painter paints the room in 3/2 hours then,
3 painters will paint the room in
3*3/2
= 4.5 hours
Thus the number of hours required are 4.5 hours .

Five friends attend a matinee movie and spend $8 per ticket. They also purchase a small bag of popcorn each. The friends spend a total of $62.50. Let x be the price of a small bag of popcorn.
Part A
Which equation represents the situation?
62.50 + 8x = 40
40 + 8x = 62.50
40 + 5x = 62.50
62.50 + 5x = 40
Part B
How much does each small bag of popcorn cost?
$
Answers
Answer:
Formula: (cost of ticket + cost of popcorn) * # of friends = total cost
Which would give us (8 + x) * 5 = 62.5
Solve for x.
8 + x = 12.5 {divide each side by 5}
x = 12.5 - 8
x = 4.5
Each small bag of popcorn costs $4.50.
hope this helps!
The equation representing the given situation is 40 + 5x = 62.50 and the price of a small bag of popcorn will be $ 4.5. Option C is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, five buddies each pay $8 for a ticket to the matinee. Additionally, they each buy a little bag of popcorn. The pals spend $62.50 altogether.
Suppose x represent the price of a small bag of popcorn.
(cost of ticket + cost of popcorn) × number of friends = total cost
⇒ (8 + x) 5 = 62.5
Simplify the equation to obtain the value of x as
⇒ (8 + x) = 62.5/5
⇒ 8 + x = 12.5
⇒ x = 12.5 - 8
⇒ x = 4.5
Thus, the equation representing the given situation is 40 + 5x = 62.50 and the price of a small bag of popcorn will be $ 4.5. Option C is correct. Option C is correct.

What is the probability that the car lot will sell at least 18 cars? __%
What is the probability that a car lot will sell at most 26 cars?__%
Answers
Answer:
first question is 10 other question it doesn't sound right to me
The answers to the blanks are as follows:
1) 18 and 22
2) 14 and 26
3) 84%
4) 99.85%
What is Standard Deviation?'The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.'
According to the given problem,
Number of cars sold each week = 20
Standard deviation = 2
= 20 + (2*2)
= 18
68% : 18 and 22
99.7% : 14 and 26
P( x ≥ 18 ) = 50% + [tex]\frac{0.68}{2}[/tex]
= 84%
P( x ≤ 26 ) = 1 - [tex]\frac{(1 - 0.99)}{2}[/tex]
= 99.85%
Hence, we can conclude that 68% will fall between 18 and 22 and 99.7% will fall between 14 and 26. We also concluded that the car lot will sell at least 18 cars is 84% and that they will sell at least 26 cars is 99.85%.
