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:

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

×7=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.

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.

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

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

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
