Answer:
26.83inches
Step-by-step explanation:
Area of the square mirror is expressed as A = L²
L is the side length of the square mirror
Given
Area = 720in²
Get the length
720 = L²
L = √720
L = 26.83
Hence the length of wood trim needed to go around the entire mirror is 26.83inches

Factorise fully the following 2x+8
Find x step by step (10 points)
Answer:
[tex]\sqrt{(n-m)(n+m)}[/tex] & [tex]-\sqrt{(n-m)(n+m)}[/tex]
Step-by-step explanation:
1) Subtract [tex]m^{2}[/tex] from both sides. This should leave you with [tex]x^{2}=n^{2}-m^{2}[/tex].
2) Square root both sides. This should leave you with [tex]x=\sqrt{n^2-m^2}[/tex] & [tex]x=-\sqrt{n^2-m^2}[/tex].
You can stop here if this is what the problem is asking for. However, it is not fully simplified.
3) Factor the equation. This should leave you with [tex]\sqrt{(n-m)(n+m)}[/tex] & [tex]-\sqrt{(n-m)(n+m)}[/tex].
[tex]\boxed{\left \{ {{\sqrt{(n-m)(m+n)}} \atop {-\sqrt{(n-m)(m+n)}}} \right.}[/tex]
Solution Steps:- Steps using the quadratic formula -______________________________
1.) Subtract n² from both sides:[tex]n^2-n^2=0[/tex][tex]m^2-n^2=m^2-n^2[/tex]2.) Rewrite:This equation is in standard form: ax² + bx² + c = 0. Substitute 1 for a, 0 for b, and (m-n) (m+n) for c in the quadratic formula, [tex]\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}[/tex]:
[tex]x^2+m^2-n^2=0[/tex]2.a) Turns into:
[tex]x=\frac{0\frac{+}{}\sqrt{0^2-4(m-n)(m+n)}}{2}[/tex]3.) Square 0:[tex]0^2=0[/tex] (Also means it Cancels out.)4.) Take the square root of −4(m−n)(m+n):This just means combine them by squaring.
[tex]-4^2=2[/tex] (Half it, don't square it.)[tex](m-n)(m+n)^2=(n^2-m^2)[/tex]4a.) Our equation should look like this now:

A garden is in the shape of a rectangle 90 m by 60 m.
Flowers are grown in 40% of the garden.
The rest of the garden is grass.
Work out the area of the garden that is grass.
Answer:
3240 sq meters
Step-by-step explanation:
Area of garden = 90*60= 5400 square meters.
Flowers grown on = 40%
So, grass grown on = (100 -40)% = 60%
60% of 5400 = 0.6*5400 = 3,240.
So, the area of the garden that is grass = 3,240 square meters
A gallon of water weighs 8.34 pounds. The Rhoads family has a round, 12-foot diameter, above-ground pool. How much weight is added to the pool when it is filled with 3, 205 gallons of water?
Answer:
The amount of weight added is 26,729.7 pounds
Step-by-step explanation:
Here, we are told that a gallon of water weighs 8.34 pounds
Now, we want to find the weight of 3,205 gallons of water
Mathematically, that would be;
3,205 * 8.34 = 26,729.7 pounds

Regional erosion occurs at a rate of 2 m per 1,000 years.
How much regional erosion will occur over 1,000,000 years?
A) 20 m
B) 200 m
C) 2,000 m
D) 100,000 m
Answer:
200
Step-by-step explanation:
It's 200 because you would take the 1,000 and multiply it by the power of 3, which is 100,000. So therefore you would do the same thing with the 2, which 2 to the power of 3 is 200. There is your explanation.

x=2-33x=-2-4x=2x+7-5x=4x+6-7Convert the rate 25 miles per hour to feet per second
Answer:
36.67 feet / second
Step-by-step explanation:We will be using Dimensional Analysis to solve this question
We are given the rate: 25 miles / hour
Converting the Miles to feet:
We know that 1 mile = 5280 feet
So, we can say that [tex]\frac{5280 feet}{1 mile}[/tex] = 1
Multiplying the Given rate by 1:
[tex]\frac{25 miles}{Hour}[/tex] * 1
(multiplying by 1 will not change the actual value of the expression)
[tex]\frac{25 miles}{Hour}[/tex] * [tex]\frac{5280 feet}{1 mile}[/tex] (since 5280 feet/ 1 mile = 1)
here, the 'mile' will cancel out and we will get:
[tex]\frac{25 * 5280 feet }{Hour }[/tex]
[tex]\frac{132000 feet}{Hour}[/tex]
Converting the Hours to Seconds:
We know that 1 hour = 3600 seconds
So, we can say that:
[tex]\frac{1 Hour}{3600 seconds}[/tex] = 1
Multiplying the Rate by 1:
[tex]\frac{132000 feet}{1 Hour} * 1[/tex]
(multiplying by 1 will not change the actual value of the expression)
[tex]\frac{132000 feet}{1 Hour} * \frac{1 Hour}{3600 seconds}[/tex] (since 1 hour / 3600 seconds = 1)
Here, the 'Hour' in the numerator and the denominator will cancel out to make:
[tex]\frac{132000 feet}{3600 seconds}[/tex]
which can be simplified to:
[tex]\frac{36.67 feet}{second}[/tex]
Therefore, 25 mph can also be written as 36.67 feet per second

9514 1404 393
Answer:
$2,070,000
Step-by-step explanation:
The series of salaries has a first term of $40,000 and a common difference of $2,000. The sum of them is given by the formula ...
Sn = (2a1 +d(n -1))(n/2)
where a1 is the first term of the series, d is the common difference, and n is the number of terms.
In this problem, we have ...
a1 = 40,000; d = 2,000; n = 30
so the sum is ...
S30 = (2(40,000) +2,000(30 -1))(30/2) = (80,000 +58,000)(15)
S30 = 2,070,000
The teacher will earn $2,070,000 over 30 years on this salary schedule.

A t-shirt printing company charges a one-time setup fee, plus a charge to print each t-shirt. The math club had 75 t-shirts printed for a cost of $424. The science club had 50 t-shirts printed for a cost of $299. What is the cost of having 170 t-shirts printed? *
Answer:
$826.70
Step-by-step explanation:
If 75 t-shirts cost $ 424, it implies that the value of each shirt is $ 5.65 (424/75). Now, in the case of the 50 shirts, the total value is $ 299, with which the value of each unit is $ 5.98.
Thus, we can see that in an increase of 50% of the units (from 50 to 75), the discount is of the order of, as it arises from the following calculation:
5.98 = 100
5.65 = X
((5.65 x 100) / 5.98) = X
94.48 = X
Thus, since 100 - 94.48 is 5.52, the discount made for the 25 shirts is 0.22% each unit (5.52 / 25). Thus, in the case of printing 170 t-shirts, taking into account this tariff system, and taking as a base price that of 50 t-shirts at $ 299, a discount of 0.22% would be made on each of the 120 remaining t-shirts. Thus, 120 t-shirts at $ 717.6 (5.98 x 120) would be added to the initial $ 299, on which a 26.4% discount (0.22 x 120) would be applied, with which the final price would be $ 527.7 (717 x 0.736).
Thus, the total price of the shirts would be $ 826.7 (that is, adding the base price of $ 299 plus the price of the 120 extra shirts of $ 527.7).

What is the axis of symmetry for the following equation?
y=4x2-8x+9
Answer:x=1
Step-by-step explanation:
The x of the top of the parabola is:
x=-(-8)/(2*4)=1
x=1
Using quadratic function concepts, it is found that the axis of symmetry for the function is x = 1.
The standard quadratic function is modeled by:
[tex]y = ax^2 + bx + c[/tex]
And has axis of symmetry given by:
[tex]x = -\frac{b}{2a}[/tex]
In this problem, the function is:
[tex]y = 4x^2 - 8x + 9[/tex]
The coefficients are:
[tex]a = 4, b = -8, c = 9[/tex]
Then, the axis of symmetry is:
[tex]x = -\frac{b}{2a} = -\frac{(-8)}(2(4)} = 1[/tex]
