The Volume of pyramid is 19.5 [tex]m^{3}[/tex].
What is pyramid?A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apx. Each base edge and apx form a triangle, called a lateral face.
What is volume of pyramid?The volume of a pyramid refers to the space enclosed between its faces.
Volume of pyramid = (1/3) (Base area * height of pyramid )
According to the question
Area of the base = 6.8 [tex]m^{2}[/tex]
Height of the pyramid = 8.6 m
now,
using the formula of Volume of pyramid
Volume of pyramid = (1/3) (Base area * height of pyramid )
substituting the values
Volume of pyramid = (1/3) ( 6.8 * 8.6 )
= 19.49 [tex]m^{3}[/tex]
Rounding off to nearest tenth of a cubic meter
Volume of pyramid = 19.5 [tex]m^{3}[/tex]
Hence, the Volume of pyramid is 19.5 [tex]m^{3}[/tex]

The radius of a circle is 8 units.
What is the diameter of the circle?
units
Answer:
16
Step-by-step explanation:
radius is 1/2 of diameter
Answer:
16 units
Step-by-step explanation:
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units.

Three cards are selected one after the other from a standard deck of 52 cards.
What is the probability that all three cards are spades if none of the first two cards is replaced?
Answer:
[tex]\frac{11}{850}[/tex]
Step-by-step explanation:
Let's see
The probability of the first card being a spade is 13/52 (as there's 13 spades in the deck.
The probability for the second card is 12/51 (because there's 12 spades left in 51 cards total).
The probability for the third is - you guessed it! - 11/50
so the total probability is:
[tex]\frac{13}{52} \cdot \frac{12}{51} \cdot \frac{11}{50} = \frac{1}{4} \cdot \frac{4}{17} \cdot \frac{11}{50} = \frac{1}{17} \cdot \frac{11}{50} = \frac{11}{850}[/tex]
A more generic solution:
Let's use the binomials to find the solution with combinations:
We need to pick 3 cards out of 13. This can be done in
[tex]\binom{13}{3} = \frac{13!}{3!\cdot10!}[/tex] ways.
And the total number of ways to pick 3 cards out of 52 is:
[tex]\binom{52}{3} = \frac{52!}{3!\cdot 49!}[/tex]
So the probability is:
[tex]\frac{ \binom{13}{3} }{ \binom{52}{3} } = \frac{ \frac{13!}{3!\cdot 10!} }{ \frac{52!}{3!\cdot 49!} } = \frac{ \frac{13!}{10!} }{ \frac{52!}{49!} } = \frac{13 \cdot 12 \cdot 11}{52 \cdot 51 \cdot 50}[/tex]
Which again brings us to the result computed before.

A store advertises 15% off an item that regularly sells for $300. what is the sale item? how is a 15% discount similar to a 15% decrease? Explain.
Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.

for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it
Cos(60) = 18 / x
I'll show you the algebra we need to use to get this formula so that we can find x
A = B / x ( this is how it looks above )
x = B / A , now just put in the parts
x = 18 / Cos(60) now solve it w/ your calculator.. :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator :/

A taxi hurries for 1 hour 54min with a constant speed of 93km and then for another 5 hours 15min with a constant speed of 72km. What distance did it go
Speed = 93km /h and 72km/h
Answer: The taxi went a distance of 554.7km
Step-by-step explanation:
Speed = Distance / Time
Distance covered in the first trip = Speed x Time
Time = 1 hour 54 min =1+0.9 hours =1.9hours
=93km / h x 1.9 hours =176.7km
Distance covered in the second trip = Speed x Time
Time = 5 hours 15min = 5+0.25hours =5.25hours
=72km / h x 5.25hours =378 km
Total distance =176.7km+378 km
=554.7km

The graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
What is a circle?A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given equation of the graph is f(x + 5)² + (y – 10)² < 169. When we plot the equation we get the circle having an inside shaded part. The coordinates of the circle are (5,-10).
Therefore, the graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
