Step-by-step explanation:
length=x
width=x-1
x + x + (x-1) + (x-1) = 54
4x - 2 = 54
4x = 56
x = 14 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
Perimeter= x + x + (x-1) + (x-1)
54 ft = 14 + 14 + (14 - 1) + (14 - 1)
54 ft = 28 + (13 +13)
54 ft = 54 ft

In the 1960s, Filipino and Latino farmworkers in California went to strike against large grape growers, demanding better working conditions, better pay and union representation union head ceaser chavez led the workers on a march to the state capital, and people across the country learned about the workers because in response millions of American stopped eating non-onion grapes eventually the growers agreed to the workers demand the combination of the farmworkers protest and the great of boycott had proven effective
Answer:
the word is boycott
Step-by-step explanation:
A boycott means to purposely refuse to use or buy a product. It is to intentionally cause a form of absenteeism in dealing with a person,a company, an organization or the government. Boycots are usually a form of protests for social, moral or political causes.it has proven overtime to be a ver useful way of protest.

Jenny is solving the equation 3 x + 5 = 4 x + 2 using algebra tiles. She cannot decide if she should add 3 negative x-tiles or add 2 negative unit tiles to both sides first. Which explains which Jenny should do first?
A.She should add 3 negative x-tiles first because that is the only way to isolate the variable.
B.She should add 2 negative unit tiles first because that is the only way to get to the correct solution.
C.She can do either one first because zero pairs will be created to isolate the variable either way.
D.She should do neither one first because the first step is to add 4 negative tiles to both sides.

3x -10+ 4x= -2 (x-4) +9
Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
3x - 10 + 4x = -2(x - 4) + 9
Step 2: Solve for x
Distribute -2: 3x - 10 + 4x = -2x + 8 + 9Combine like terms: 7x - 10 = -2x + 17Add 2x to both sides: 9x - 10 = 17Add 10 to both sides: 9x = 27Divide both sides by 9: x = 3Step 3: Check
Plug in x to verify it's a solution.
3(3) - 10 + 4(3) = -2(3 - 4) + 9
9 - 10 + 12 = -2(-1) + 9
-1 + 12 = 2 + 9
11 = 11
Explain how the Distributive Property can be used to solve the equation.

x + (2x + 40) + (3x – 50) = 15,002
Answer:
x = 2,502
Step-by-step explanation:
x + (2x + 40) + (3x – 50) = 15,002
~Combine like terms
6x - 10 = 15,002
~Add 10 to both sides
6x = 15,012
~Divide 6 to both sides
x = 2,502
Best of Luck!
Answer:
x = 2,502
Step-by-step explanation:
x + (2x + 40) + (3x - 50) = 15,002
Combine Like Terms
6x -10 = 15,002
Add 10 on both sides of the equation
6x = 15,012
Divide both sides by 6
x = 2,502

My TI-83 calculator was worth $75 after I owned it for 2 years. Since the new and improved TI-84 came out, the price of the calculator keeps going down. After 8 years, it is now worth only $10. Write an equation to model this situation and use it to predict when the calculator will be worth $2. Show all work.
Answer:
It will take approximately 13 years for the calculator to be $2
Step-by-step explanation:
We need to set up a depreciation equation for the cost of the calculator per year.
Let the initial cost be I, the present value be P and the depreciation percentage be r%
Thus;
P = I( 1 - r%)^t
r% is same as r/100
For the two years initially;
75 =I( 1 - r/100)^2•••••••••(i)
For the 8 years, we have the equation as
10 = I(1 - r/100)^8 ••••••••(ii)
Now, simply divide the second equation by the first directly; we have;
10/75 = (1 - r/100)^8 / (1 - r/100)^2
2/15 = (1-r/100)^6
Take the log of both sides
ln(2/15) = ln(1-r/100)^6
ln(2/15) = 6 ln (1-r/100)
-2.015 = 6 ln (1 - r/100)
divide both sides by 6
-0.34 = ln (1-r/100)
1-r/100 = e^(-0.34)
1-r/100 = 0.715
Multiply through by 100
100 - r = 71.5
r = 100-71.5
r = 28.5%
Let’s now calculate the initial value;
P = I( 1 - r/100)^t
Let’s use the two years time frame
75 = I( 1 - 28.5/100)^2
75 = I(0.715)^2
I = 75/(0.715)^2
I = 146.71 which is approximately $147
Now, the time it will take for the calculator to be $2
P = I(1-r/100)^t
2 = 147 ( 1 - r/100)^t
divide both sides by 147
0.014 = (0.715)^t
ln 0.014 = ln (0.715)^t
t ln 0.715 = ln 0.014
t = ln 0.014/ln 0.715
t = 12.72
t is approximately 13 years

what is i^85 HELP
PLEASE!!!!!!!!!!!!!
Answer:
the answer to your question is b
The value of the given expression is i. Therefore, the correct answer is option B.
The given expression is i⁸⁵.
An imaginary number is a real number multiplied by the imaginary unit i, which is defined by its property i² = −1.
Here, i⁸⁵ can be written as i⁸⁵=i⁸⁴×i
= (i²)⁴⁸×i
= (-1)⁴⁸×i
= 1×i
= i
Therefore, the correct answer is option B.

The prime factorization of a number is . Which statement is true about the factors of the number? Twenty-one is a factor of the number because both 3 and 7 are prime factors. Twenty-one is not a factor of the number because 21 is not prime. Ninety is a factor of the number because and 90 is divisible by 9. Ninety is not a factor of the number because 90 is not divisible by 7.
Answer & Step-by-step explanation:
Factors of a number are the number(s) whose product ie multiplication gives the number. Prime factorisation is finding 'prime' factors of numbers, ie the numbers which dont have a factor further - other than themselves & 1.
Example : 6 = 2 x 3, so 2 & 3 are factors of 6. Also, 2 & 3 are prime factors, as they dont have further multiplication factors, other than themselves (2 & 3 respectively) & 1. So this can be an illustrative case of prime factorisation of 6.
Answer:
Answer:
Twenty-one is a factor of the number because both 3 and 7 are prime factors.
Step-by-step explanation:
Given number is,
3^2\times 5^3\times 73
2
×5
3
×7
=3\times 3\times 5\times 5\times 5\times 7=3×3×5×5×5×7
Where, 3, 5 and 7 are prime numbers ( only divisible by 1 and itself ),
⇒ Both 3 and 7 are prime factors of the given number,
⇒ 21 is a factor of the given number.
Thus, first option is correct.
⇒ Second option is incorrect.
Now, 5 is factor of the given number but 2 is not,
⇒ 10 is not a factor of the given number,
⇒ 90 is not a factor of the given number,
⇒ Third option is incorrect.
Suppose 90 is divisible by 7,
⇒ 90 = 7a
Where a is any whole number,
⇒ 7=\frac{90}{a}7=
a
90
3^2\times 5^3\times 7=3^2\times 5^3\times \frac{90}{a}3
2
×5
3
×7=3
2
×5
3
×
a
90
Since, 90 could be a factor of this number, if a = 3 or 5 or their multiple,
For the other values of a, 90 can not be the factor,
Hence, there is no effect of divisibility of 90 by 7 on having 90 as a factor of the given number,
⇒ Fourth option is incorrect.
