Answer:
x=6,-6
Step-by-step explanation:
-x^2=-36
x^2=36(cancel the signs) (divide 36 on both sides)
x=+-6
X=6,-6
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

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.

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

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.

If 1/5 of a pizza has 380 calories, how many calories are in 1/8 of that pizza?
Answer:237.5
Step-by-step explanation: 380x5=1900, 1900/8=237.5
The required calories in 1/8 of a pizza is 237.5 calories.
Given that, 1/5th of a pizza has 380 calories. To calculate calories in 1/8 of the pizza by using concept of proportion.
Let a, b, c and d be any real numbers. Consider these four number are in proportion such that a : b : : c : d. That gives, a/b = c/d.
Let "x" represent the number of calories in 1/8 of the pizza.
By using proportion,
(1 / 5) / (1 / 8) = 380/x.
Dividing fraction is by multiplying first fraction with reciprocal of second fraction.
(1/5) × (8/1) = 380/x.
8/5 = 380/x.
By cross multiplication, gives,
8x = 380 × 5= 1900.
x = 1900/8 = 237.5.
Hence, the required calories in 1/8 of a pizza is 237.5 calories.
