Rectangle with a length of 96 inches and width of 60 inches. A rug maker wants to increase each dimension by a different amount.

mr Goodwill [35]

Answer:

The perimeter of the new rectangle in simplified expression can be given as:

$2l+2w+312$

Step-by-step explanation:

The question is incomplete.

The actual question should be:

A rug maker is using a patter that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches of the length and width. write and simplify an expression for the perimeter of the new pattern.

Solution:

Original length of the rectangular pattern = 96 inches

Original width of the rectangular pattern = 60 inches

Let increase in length be = $l$ inches

New length of rectangle = $(96+l)$ inches

Let increase in width be = $w$ inches

New width of rectangle = $(60+w)$ inches

The perimeter of a rectangle is given by :

⇒ $2(length+width)$

Substituting the new length and width of the triangle.

⇒ $2(96+l+60+w)$

Simplifying.

⇒ $2(l+w+156)$

Using distribution.

⇒ $2l+2w+312$

Thus, the perimeter of the new rectangle in simplified expression can be given as:

$2l+2w+312$

Precal please help me

OlgaM077 [116]

Answer:

a) 910

b) 1183

c) False

take these answers with a grain of salt, i cant guarantee accuracy but the process should be right?

Step-by-step explanation:

a)

Starting with 1300 dollars, we are given that the stock loses 30% of its value.

This means that we take 70% of 1300 as it is now at 70% of its value. This gives us 910.

b)

At 910 dollars, we are told that the stock's value rises by 30%, so if we multiply 910 by 1.3 or 130%, we get 1183. At this time, the stock is now worth 1183 dollars.

c)

It is false, as can be seen above a 30% loss followed by a 30% gain results in 91% of the original price. That's a 9% net loss.

This can be seen using variables, x -> 0.7x -> 0.7*1.3 x -> 0.91 x

Mark ran a mean distance of 13.2 km in five days. The next day, Mark ran 20 km.

Evgen [1.6K]

Answer:

14.3 km (1 d.p.)

Step-by-step explanation:

To find the mean, divide the sum of all data values by the total number of data values.

If Mark ran a mean distance of 13.2 km in five days, we can use the mean distance for each of the 5 days in our calculation.

$\begin{aligned}\implies \sf mean\:distance & = \sf \dfrac{13.2+13.2+13.2+13.2+13.2+20}{6}\\ & \sf =\dfrac{86}{6}\\\\ & = \sf 14.3\:km\:\:(1\:d.p.)\end{aligned}$

Simplify the expression answer must be in positive exponents a^7/a^3

Liono4ka [1.6K]

Answer:

a⁴

Step-by-step explanation:

Given expression:

$\sf \dfrac{a^7}{a^3}$

To simplify the expression, we can apply the following rule: $\sf \dfrac{x^m}{x^n}=x^{m-n}$ . This is known as the Quotient of Powers Property, which states that when dividing two powers with the same base, the exponents are subtracted.

$\sf \implies \dfrac{a^7}{a^3}=a^{7-3}=\boxed{\sf a^4}$
