(8 x 9) x (2 x 5) is the correct answer.
Step-by-step explanation:
(8 x 9)= 72
(2 x 5)= 10
72 x 10 = 720
(8 x 9) x (2 x 5) is the expression can be used to find the product of 720

We need to find the expression can be used to find the product of 720
Product is nothing but multiplication.
Multiplication is a method of finding the product of two or more numbers
(8 x 9) x (2 x 5)
Eight time of nine times two times of five
Eight times of nine is seventy two and two times of five is ten
72×10
Seventy two times of ten is Seven hundred twenty
720
Hence, (8 x 9) x (2 x 5) is the expression can be used to find the product of 720

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
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.

Answer:
1?
Step-by-step explanation:
The number that when multiplied by any other number, the answer will always be the same is 1.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
When you multiply any number by 1, the product is always the same as the original number.
For example, 5 times 1 is 5, and 100 times 1 is 100.
So 1 is known as the multiplicative identity because it has the special property that when it is multiplied by any number, the result is always the same as that number.

Sam spent $1.08 to make 18 copies at office max.At that rate how much will he pay to make 40 copies?
Answer:
$2.40
Step-by-step explanation:
If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.

Find the volume of a hemisphere with a radius of 8. Round to the nearest tenth.
Answer:
V(hemisphere) = 1072.3in^3
Step-by-step explanation:
To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.
The volume of a sphere is:
[tex]V(sphere) = \frac{4}{3} \pi r^3[/tex]
Let's plug in the radium of 8 into the equation and solve:
[tex]V(sphere) = \frac{4}{3} \pi (8)^3\\V(sphere) = \frac{4}{3}\pi 512 \\V(sphere) = 2144.660585[/tex]
Now, divide it by 2
V(sphere) = (2144.660585)/2
V(hemisphere) = 1072.3in^3

The decibel level of the sound of a monster truck is
Further explanation:
Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.
In the question it is given that the intensity of the sound of a monster truck is watts per square inch.
The formula which is used to calculate the decibel level of a sound is as follows:
Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .
The value of the threshold intensity of hearing at is watts per square meter.
This implies that the valiue of is watts per square meter.
The intensity of the sound of a monster is given in unit of per square inch.
The relation between per square inch and per square meter is as follows:
So, the intensity of a monster truck is converted into per square meter as follows:
This implies that the value of is watts per square meter.
Now, substitute the value of and in the equation .
The approximated value of the above equation is as follows:
From the above calculation it is concluded that the decibel level of the sound of a monster truck is .
