Find the value of x. A B X 6 3 2 D x = [?] C

Enter an algebraic expression to model the given context. Give your answer in simplest form. The original price p of an item les

ra1l [238]

Answer:

Step-by-step explanation:

Let

Original price = p

Less Discount = 20%

Total discount paid for the item = 20% of p

= 20/100 * p

= 0.2 * p

= 0.2p

Actual price after discount = 100% - 20%

= 80%

Total price paid for the item = 80% of p

= 80/100 * p

= 0.8 * p

= 0.8p

Li Ping says a square with 3 inch sides has greater area than a parallelogram that is not a square but has sides that have the s

Kipish [7]

Answer:

Li Ping's statement makes sense.

Step-by-step explanation:

The area of a square with side lengths a inches is given by, $A_1 = a^{2}$ .

Now, the area of a parallelogram with equal sides a inches, which is not a square is given by, $A_2 = ah$ , where, h is the perpendicular distance between the opposite sides.

See the diagram attached.

Since a is the hypotenuse of as right triangle with height h, hence, a > h.

So, $A_1 > A_2$

Therefore, Li Ping's statement makes sense. (Answer)

The height of a cylinder is twice the radius of its base.

Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be $2x$ .

Now we will use volume of cylinder formula to our given problem.

$V=\pi r^2h$ , where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

$V=\pi\cdot x^2\cdot 2x$

$V=2x^3\pi$

Therefore, our required volume expression would be $2x^3\pi$ .

How do you determine what your grade average is based on the following grades?:

fiasKO [112]

Answer:

Test's average-95

Homework's average-96.67

Step-by-step explanation:

Average is mathematically defined as the sum of the values divided by the total number of values and is expressed as:

$\bar X=\frac{1}{n}\sum{x_i}, n=number \ of \ values.$

The Tests' average is calculated as:

$\bar X_t=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{3}(98+92+95)\\\\=\frac{1}{3}\times 285\\\\=95$

Hence, the Tests' average is 95

#The Homework's average is calculated as:

$\bar X_h=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{3}(93+97+100)\\\\=\frac{1}{3}\times 290\\\\=96.67$

Hence, the Homework's average is 96.67
