Which monomials are perfect cubes? Check all that apply.3x3
8x12
27x9
100x3
125x5

Answers

Answer 1

Answer:

When a number is multiplied by itself three times, then the resultant number is called a perfect cube. It is also a number with an exact cube root.

Out of the given options, $8x^(12)$ and $27x^(9)$ are perfect cubes.

$8x^(12)$ = $2x^(4)* 2x^(4)* 2x^(4)$ (2's are multiplied and powers are added)

$27x^(9)$ = $3x^(3)* 3x^(3)* 3x^(3)$ (3's are multiplied and powers are added)

Answer 2

Answer:

The monomials that are perfect cubes out of the options given are: B. 8x^12, and C. 27x9.

What is a Perfect Cube?

A perfect cube is a number that can give you a precise cube root, i.e. a³ = a × a × a = ∛a³ = a.

27x^9 can be expressed as: ∛(27x^9) = 3x³

8x^12 can be expressed as: ∛(8x^12) = 2x^4

Therefore, the perfect cubes are: B. 8x^12, and C. 27x9.

Simplify 4 + (−3) − 2 × (−6)

Keywords:

Simplify, expression, order of operation, PEMDAS

For this case we must simplify the given expression, we must take into account the order of operation (sequence in which operations must be performed) known as PEMDAS:

P: Parentesis

E: Exponents

M: Multiplication

D: Division:

A: Addition

S: Subtraction

In the given expression, we see that we have multiplication and addition, according to the PEMDAS rule, we must first do the multiplication:

So:

$4 + (-3) - 2 * (-6) =$

We multiply, taking into account that: $- * - = +$

$4 + (- 3) + 12 =$

We add similar terms:

$12+4-3=$

$16-3 =$

Different signs are subtracted and the sign of the major is placed:

$4 + (-3) - 2 * (-6) = 13$

Answer:

By simplifying $4 + (-3) - 2 * (-6)$ we get 13 as a result.

2.-6=-12
4+(-3)-(-12)
13

Mary throws a plastic disc to her friend, which her friend catches six seconds after Mary throws it. The table shows the height of the disc at one-second intervals. Assuming that the throw represents projectile motion, what are the missing values in the table?

Answers

Unfortunately, there is no given table. However, assuming no air resistance, the projectile moves in constant acceleration in the y-axis, while constant velocity in the x-axis. If the total time of flight is 6 seconds, then at 3 seconds the reaches its maximum height. Also, there is no given initial velocity, which means any useful calculation is impossible.

Answer:

The answer is A = 4 and B = 3 or C on edge

Write the ratio 2/11 to 7/11 as a fraction in the lowest terms.

Answers

The lowest term for 2/11 is 2/11 because it can not be reduced. The lowest term for 7/11 is 7/11 to because it can not be reduced

Final answer:

The ratio of 2/11 to 7/11 simplified as a fraction in the lowest terms is 2/7. This was done by canceling out the like terms in both fractions, essentially dividing both numbers in the ratio by the common factor of 11.

Explanation:

To write the ratio 2/11 to 7/11 as a fraction in the lowestterms, you are essentially finding the ratio of these two fractions. Starting from the fractions 2/11 and 7/11, we 'cancel out' the like terms in both fractions. Remember, a ratio is simply a way of comparing two or more numbers. So the ratio of 2/11 to 7/11 simplifies to:

2/11 : 7/11 = 2/7

So, the ratio 2/11 to 7/11 as a fraction in the lowest terms is 2/7. This was achieved by dividing both numbers in the ratio by the common factor of 11.

What would my final balance be if i put R650 in the bank for 60 Months with an interest rate of 6%

Answers

60 months is 5 years
12 × 5 = 60

Interest = Principle amount × Rate × Time in years
= 650 × 0.06 × 5 (6% = $(6)/(100)$ = 0.06)
= R195

R650 + R195 = R845
