What was the original price if: after 10% discount it becomes $450?

Answers

Answer 1

Answer:

Answer: Original Price=$450

Step-by-step explanation:

Price post discount=$450

Discount=10%

Let the original price be x

Given x - 10% of x=450

$x-(10)/(100)* x$

$(100x-10x)/(100)$ =450

$(90x)/(100)$ =450

x= $(100*450)/(90)$

On solving

x=500$

The original price =500$

Answer 2

Answer:

The original price before the 10% discount was about $500.

What is the original price?

To know the original price before the discount, one can use the following formula:

Original Price = Discounted Price / (1 - Discount Percentage)

So, the discounted price is $450, and the discount percentage is 10%.

To calculate the original price:

Original Price = $450 / (1 - 0.10)

= $450 / 0.90

- $500

Therefore, the original price before the 10% discount was about $500.

What is the total surface area of a right rectangular prism with a base of 2 cm by 3 cm and a height of 6 cm? A) 13 cm2. B) 72 cm2. C) 113 cm2. D) 226 cm2.

Answers

Answer: $=72\ cm^2$ ,

Step-by-step explanation:

The total surface area of a right rectangular prism is given by :-

$\text{Total surface area}=2(lw+wh+hl)$ , where h is height, w is width and l is length of the prism.

Given: Height = 6 cm

Dimensions of base = 2 cm by 3 cm

Now, the total surface area of a given right rectangular prism is given by :-

$\text{Total surface area}=2(2\cdot+3\cdot6+2\cdot6)=2(6+18+12)=2(36)=72\ cm^2$ ,

(L · W · 2) + (perimeter of the base · height). For this prism, that's (2 cm · 3 cm · 2) + (2 cm + 2 cm + 3 cm + 3 cm) · 6 cm. This is (12 cm2) + (10 cm · 6 cm) = 72 cm2.

64/81=(8/9) what is the exponent

Answers

Answer:

2 is the exponent

Step-by-step explanation:

Given is an equation as

$(64)/(81) =((8)/(9) )^m$

and we have to find the exponent m

Since 64 and 81 are prime to each other we cannot simplify the fraction.

We find that both 64 and 81 are perfect squares of 8 and 9 respectively

Hence we write

$(64)/(81) =((8^2)/(9^2) )\n(64)/(81) =((8)/(9) )^2$

Comparing m =2

Hi

x = exponent

64 = 8·8 = 8^2
81 = 9·9 = 9^2

64/81 = 8^2/9^2 = (8/9)^2

(8/9)^2 = (8/9)^x

x = 2

Answer:

The parallelograms PQRS and TUVW are not alike.

Step-by-step explanation:

In a parallelogram, if one angle is known, then all the other angles can also be determined.

Now, parallelograms PQRS and TUVW have one angle of 120° equal.

So, the other three angles will be the same for them.

The adjacent sides of the parallelogram PQRS are 8 ft and 12 ft. and the adjacent sides of the parallelogram TUVW are 2.4 ft and 5.2 ft.

So the ratios of sides of the two parallelograms are $(8)/(2.4) = 3.33$ and $(12)/(5.2) = 2.3$ which are not equal.

So, the parallelograms PQRS and TUVW are not alike. (Answer)

What is an integer exponent?

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that the expression:

$= \rm (\sqrt[5]{x} )^7$

As we know, the expression can be defined as the combination of constants and variables with mathematical operators.

From the properties of the integer exponent:

Integer exponents are exponents that should be integers. It may be a positive or negative number

Applying the properties of the integer exponent:

$= \rm x^{(1)/(5)}^(* 7)$

$= \rm x^{(7)/(5)}$

Thus, the radical expression is an expression with rational exponents that can be written after applying the properties of the integer exponent.
