Mrs. Thomas has two rolls of garden edging that are each 96 inches long.

She wants to make two new flower beds in her back yard. Each flower bed

will be bordered by one roll of the edging. One flower bed will be in the

shape of a quadrilateral. The other will be in the shape of a triangle.


Please answer all parts. I will give brainliest for correct answer!

Answers

Answer:

A) The total length of each edging in her scale drawing would be 19.2 centimeters.

B) Square or rectangle

C) angle  α= 53.13 degrees

angle β=  36.87 degrees

height=  32 inches

base= 24 inches

hypotenuse 40 inches.

Step-by-step explanation:

Part A:

If the roll edging is 96 inches long and the scale chosen is

5inches = 1 cm

96inches /5= 19.2cm

The total length of each edging in her scale drawing would be 19.2 centimeters.

Part B:

The quadrilaterals such rectangle square right  trapezoid have a pair of 90 degrees angles.

If we choose a square shape then all sides must be equal. And we have a length of 19.2 centimeters.

Dividing 19.2 by 4  gives 4.8 cm for each side.

Figure A  shows a square and has 4 sides equal and 4 right angles.

If we choose a rectangle shape then 2 sides must be equal. We have a length of 19.2 centimeters.

Suppose the length is 2 times more than the width

which will give the dimensions as

2*2 x+ 2x= 6x   ( length and width denoted by x)

Dividing 19.2 by 6  gives 3.2 cm for each width and  6.4 for the lengths.

Figure B shows a rectangle  and has 2 sides equal and 4 right angles.

It depends on which quadrilateral you wish to choose.

Part C:

Using Pythagorus theorem if the base and altitude are given then the hypotenuse can be found out using the following formula.

c²= a² +b²

c²= 6.4² +4.8²

c²= 40.96+23.04= 64

c= √64 = 8

The third side must be equal to 8 centimeters.

Using the formula

Cos α= base / hypotenuse

Cos α=4.8/8

α= Cos (inverse) 4.8/8

α= Cos (inverse) 0.6

α= 53.13 degrees

So angle α= 53.13 degrees

All the angles in the triangle must be 180 degrees.

α + β +  90°= 180°

And angle β= 180-90-53.13= 36.869= 36.87 degrees

The actual dimensions of this triangle are

height= a= 6.4* 5= 32 inches

base= b= 4.8*5= 24 inches

hypotenuse= 8*5= 40 inches.

solve
[tex]\sf \dfrac{1}{p} + \dfrac{1}{q} + \dfrac{1}{x} = \dfrac{1}{p + q + x}[/tex]

Answers

Answer:

[tex] \displaystyle \begin{cases} \displaystyle {x} _{1} = - p \\ \displaystyle x _{2} = - q \end{cases}[/tex]

Step-by-step explanation:

we would like to solve the following equation for x:

[tex] \displaystyle \frac{1}{p} + \frac{1}{q} + \frac{1}{x} = \frac{1}{p + q + x} [/tex]

to do so isolate [tex]\frac{1}{x}[/tex] to right hand side and change its sign which yields:

[tex] \displaystyle \frac{1}{p} + \frac{1}{q} = \frac{1}{p + q + x} - \frac{1}{x} [/tex]

simplify Substraction:

[tex] \displaystyle \frac{1}{p} + \frac{1}{q} = \frac{x - (q + p + x)}{x(p + q + x)} [/tex]

get rid of only x:

[tex] \displaystyle \frac{1}{p} + \frac{1}{q} = \frac{ - (q + p )}{x(p + q + x)} [/tex]

simplify addition of the left hand side:

[tex] \displaystyle \frac{q + p}{pq} = \frac{ - (q + p )}{x(p + q + x)} [/tex]

divide both sides by q+p Which yields:

[tex] \displaystyle \frac{1}{pq} = \frac{ -1}{x(p + q + x)} [/tex]

cross multiplication:

[tex] \displaystyle x(p + q + x) = - pq[/tex]

distribute:

[tex] \displaystyle xp + xq + {x}^{2} = - pq[/tex]

isolate -pq to the left hand side and change its sign:

[tex] \displaystyle xp + xq + {x}^{2} + pq = 0[/tex]

rearrange it to standard form:

[tex] \displaystyle {x}^{2} + xp + xq + pq = 0[/tex]

now notice we end up with a quadratic equation therefore to solve so we can consider factoring method to use so

factor out x:

[tex] \displaystyle x( {x}^{} + p ) + xq + pq = 0[/tex]

factor out q:

[tex] \displaystyle x( {x}^{} + p ) +q (x + p)= 0[/tex]

group:

[tex] \displaystyle ( {x}^{} + p ) (x + q)= 0[/tex]

by Zero product property we obtain:

[tex] \displaystyle \begin{cases} \displaystyle {x}^{} + p = 0 \\ \displaystyle x + q= 0 \end{cases}[/tex]

cancel out p from the first equation and q from the second equation which yields:

[tex] \displaystyle \begin{cases} \displaystyle {x}^{} = - p \\ \displaystyle x = - q \end{cases}[/tex]

and we are done!

Jessica went shopping for a new watch. She found a watch that was originally priced at $50 on sale for $40. By what percent had the watch been marked down?

Answers

Answer:

20%

Step-by-step explanation:

We were given a price at $50 on sale for $40. To get the markdown percentage, take the amount of money you've discounted the merchandise at and divide it by the sales price.

$50 sweaters, you can put them on sale for $40.

[tex]50 - 40 = 10[/tex]

The difference between these two prices is $10.

Now, we need to add the amount of which it was marked down

[tex]10 + 10 = 20[/tex]

Therefore, the watch has been marked down by 20%.

Written as a simplified polynomial in standard form, what is the result when (3x+7)^2 is subtracted from 3?

Answers

Given:

[tex](3x+7)^2[/tex] is subtracted from 3.

To find:

The result of the given statement in the standard form of the polynomial.

Solution:

We need to find the result when [tex](3x+7)^2[/tex] is subtracted from 3.

So, the resulted polynomial can be written as:

[tex]P(x)=3-(3x+7)^2[/tex]

On simplification, we get

[tex]P(x)=3-((3x)^2+2(3x)(7)+(7)^2)[/tex]               [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]

[tex]P(x)=3-(9x^2+42x+49)[/tex]

[tex]P(x)=3-9x^2-42x-49[/tex]

[tex]P(x)=-9x^2-42x-46[/tex]

Therefore, the resulted polynomial in standard form is [tex]-9x^2-42x-46[/tex].
