The formula to determine the period of one swing of a simple pendulum is T=2\pi\sqrt{\frac{L}{g}},T=2π g L , where LL is the length of the string and gg is the acceleration due to gravity. Solve the formula to solve for LL in terms of \pi,π, TT and g.G.
Answers
Answer:
L = (T² × g) / 4π²
Step-by-step explanation:
T = 2π√L/g
Where,
L = length of the string
g = acceleration due to gravity
T = 2π√L/g
square both sides of the equation to eliminate the square root
T² = (2π)²√(L/g)²
T² = (2π)²(L/g)
(2π)²
= 2π × 2π
= 4π²
T² = 4π²(L/g)
Multiply both sides by g
T² × g = 4π²(L/g) × g
T² × g = 4π²L
Divide both sides by 4π² to get L
L = (T² × g) / 4π²

Triangle JKL has an area of in2 and a perimeter of in.
Answers
Answer:
Area = 24 in²
Perimeter = 24in
Step-by-step explanation:
To find the area given the length of the 3 sides:
a= 8in
b= 6.4in + 3.6in= 10in
c= 6in
Add them together:
8in + 10in + 6in
= 24in²
To find the perimeter you do the same thing:
a= 8in
b= 10in
c= 6in

At Superior Engraving, a trophy costs $12.50 and engraving on the trophy costs $0.40 per letter. At another store, Duluth Trophy, the same trophy costs $14.75 and engraving costs $0.25 per letter. How many letters must be engraved for the costs to be the same at both places?
Answers
Answer:
The answer is 15 words
Step-by-step explanation:
Taking the problem as a algebraic expression, we get
[tex]12.50 + 0.40x = 14.75 + 0.25x[/tex]
Now, subtracting 12.50 + 0.25x from both sides, we get
[tex]0.15x = 2.25[/tex]
Therefore,
No of words = 2.25/0.15 = 15
Peter makes $15 an hour working at the grocery store and $12 an hour babysitting. He needs to make a minimum of $325 for a new bike. Which inequality best represents the situation, where g represents the number of hours at the grocery store and b represents the number of hours babysitting?
Answers
Answer:
15g + 12b ≥ 325
Step-by-step explanation:
g represents the number of hours at the grocery store
b represents the number of hours babysitting?
We are told that he need to make a minimum of: $325 for a new bike
Minimum means at least $325
Therefore, our inequality equation that best represents the situation is:

There are 2 triangles in the square XARS. Squares are always congruent, all sides are the same. Given that WT is 6, we can assume that RS is also 6 (because of congruency). RA is is the hypotenuse of the triangle ARS. To find AS, we can plug in the pythagorean theorem 6^2+x=^2=10^2. We end up getting square root of 64 which simplifies to 8. AS is now 8. We also know that ST is 6 since the square WRST has all congruent sides. 8+6=14 gives us line AT. TZ is 8 due to triangle XAR and the congruency theorem. Now we plug in pythagorean theorem to find AZ and we get 8^2+10^2=x^2. After simplifying the square root of 164, we see that AZ is equal to 12.80

While practicing her foul kicks for soccer, Louisa made 85% of her shots. If she made 51 shots, how many shots did she kick in total?
Answers
Answer:
the exact answer is 58.65
Step-by-step explanation:
since she made 85% of her shots, that means in total from her 51 shots, she made 115% more than 51 (you add 15% to 100%). The 15% is from the difference of 100% and 85%. You then change 115% to fraction form (1.15) and multiply it by the amount of shots made, getting you 58.65. Since you can't make a fraction in terms of a real life scenario like this, you prob need to round or something. Diff teachers want diff things
write in standard form if needed classify the polynomial 14y^2-x^2-3xy
Answers
Therefore, we can classify the polynomial as a quadratic polynomial.
What is polynomial?A polynomial is a mathematical expression that consists of variables and coefficients, and involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and may contain multiple terms. Each term consists of a coefficient and a variable raised to a power. The degree of a term is the power to which the variable is raised, and the degree of a polynomial is the highest degree of any of its terms. Polynomials are used in many areas of mathematics, science, and engineering, such as algebra, calculus, geometry, and physics. They are used to model real-world phenomena, to solve equations, and to approximate complex functions.
Here,
To write the polynomial 14y² - x² - 3xy in standard form, we need to arrange the terms in descending order of degree (highest degree term first) and combine like terms.
First, let's rearrange the terms:
x² - 3xy + 14y²
Now, the polynomial is in descending order of degree. We don't need to do anything else to put it in standard form.
To classify the polynomial, we count the number of terms and the highest degree of those terms. In this case, there are three terms and the highest degree term is 14y², which has degree 2.

The company in the example on page 301 decides to increase the capacity of its large bottles from 32 fl oz to 40 fl oz. It plans to keep the ratio of capacity to cost the same. How much should the company charge for a bottle that holds 40 fl oz
Answers
Answer:
Cost of new bottle = 1.25a
Step-by-step explanation:
Given:
Volume of old bottle = 32 fl oz
Volume of new bottle = 40 fl oz
Computation:
Assume price ratio of old bottle = a
So,
Price ratio of new bottle [Compare by capacity] = [40/32]a
Cost of new bottle = 1.25a

2). 7+2x=3x+3=4 True or False

Answers
The first equation given as 7x + ( -6 ) = 6x - 2 is True.
The second equation given as 7 + 2x = 3x + 3 = 4 is false
How to find if the equation is true or false
Given data
7x + ( -6 ) = 6x - 2
7 + 2x = 3x + 3 = 4
The first equation
7x + ( -6 ) = 6x - 2
solving for x gives
7x - 6 = 6x - 2
7x - 6x = 6 - 2
x = 4
checking for the value
7x + ( -6 ) = 6x - 2
7 * 4 - 6 = 6 * 4 - 2
28 - 6 = 24 - 2
22 = 22
Hence we say the expression in the first equation is true
The second equation
7 + 2x = 3x + 3 = 4
7 + 2x = 3x + 3
7 - 3 = 3x - 2x
4 = x
checking for the value of x
7 + 2x = 3x + 3
7 + 2 * 4 = 3 * 4 + 3
7 + 8 = 12 + 3

15 = 15 ≠ 4 false
The first equation is true while the second equation is false

what was the ratio of the number of sedans to the number of suvs produced by company x last year? 1) last year, if the number of sedans produced by company x had been 8 percent greater, the number of sedans produced would have been 150 percent of the number of suvs produced by company x 2) last year, company x produced 565,000 sedans and 406,800 suvs
Answers
The ratio is 25:18.
This problem is related to the ratio and proportion.
here it's miles given that if the number of sedans produced by organisation x have been extra by using 8% then the quantity would be one hundred fifty % of the quantity of SUVs.
1) Let that the number of sedan produced be x and number of SUVs be y.
Now according to question,
[tex]x+\frac{8}{100}*x =\frac{150}{100}*y[/tex]
⇒[tex]\frac{108x}{100}=\frac{150y}{100}[/tex]
⇒[tex]\frac{x}{y} =\frac{150}{108}[/tex]
∴ x : y=25 : 18
2) Now again the ratio =[tex]\frac{565000}{406800}[/tex]
=[tex]\frac{5650}{4068}[/tex]
= [tex]\frac{25}{18}[/tex]
So, the ratio of the number of sedans to the number of SUVs is 25:18.
