Answer:

Option (4) is correct.

The length of one side of the sandbox is $7y^4-13x^3$ inches.

Step-by-step explanation:

Given : Joan is building a sandbox in the shape of a regular pentagon. The perimeter of the pentagon is $35y^4-65x^3$ inches.

We have to find the length of one side of the sandbox.

Since, given sandbox is in shape of a regular pentagon.

So, Perimeter of pentagon is 5 times sides.

Perimeter of pentagon = 5 × sides

Given Perimeter is $35y^4-65x^3$ inches.

Thus, $35y^4-65x^3$ = 5 × sides

Divide both side by 5, we get,

$7y^4-13x^3$ = sides

Thus, The length of one side of the sandbox is $7y^4-13x^3$ inches.

Mr X went shopping with a certain amount of money. He spent Rs. 10(¼) on buying a pen and Rs. 25(¾) in food. He then gave the re

ANEK [815]

Answer:

Rs. 52 $\frac{1}{2}$

Step-by-step explanation:

Given parameters:

Amount spent on buying a food = Rs. 25.75

Amount spend on buying pen = Rs. 10.25

Amount given out to friend = Rs. 16.5

Unknown:

The total money he initially had = ?

Solution:

The total money he initially had :

= amount spent on food + amount spent on pen + amount given to friend

= Rs. 25.75 + Rs. 10.25 + Rs. 16.5

= Rs. 52.5 or Rs. 52 $\frac{1}{2}$

Firewood is stacked in a pile. The bottom row has 20 logs, and the top row was 14 logs. Each row has one more log than the row a

Lyrx [107]

Since, each row has one more log than the row above it

so, this is arithematic sequence

We are given that

First row is

$=14$

so,

$a_1=14$

Last row is

$=20$

so,

$a_n=14$

Each row has one more log than the row above it

so,

$d=1$

now, we can find number of rows

$a_n=a_1+(n-1)d$

we can plug values

$20=14+(n-1)1$

we can solve for n

$6=(n-1)1$

$n=7$

now, we can find total number of logs

$S=\frac{n(a_1+a_n)}{2}$

now, we can plug values

$S=\frac{7(14+20)}{2}$

$S=\frac{7(14+20)}{2}$

$S=119$

So,

Number of logs in the pile are 119........Answer

Answer:

The width is: $w(x)=4x^2$

The length is $l(x)=2x^2+3x+5$

Step-by-step explanation:

The given rectangle has area given algebraically by the function:

$a(x)=8x^5+12x^3+20x^2$

The width of the rectangle is the greatest common factor of $8x^5$ , $12x^3$ and $20x^2$

That is the width is: $w(x)=4x^2$

We now divide the area by the width to obtain the length of the rectangle:

$l(x)=\frac{8x^5+12x^3+20x^2}{4x^2}$

This simplifies to:

$l(x)=\frac{8x^5}{4x^2}+\frac{12x^3}{4x^2}+\frac{20x^2}{4x^2}$

$l(x)=2x^2+3x+5$
