Write 56 as a product of primes.<br> Use index notation when giving your answer.

mixas84 [53]

Answer:

56 as a product of primes using index notation is: $\mathbf{2^3 \times 7}$

Step-by-step explanation:

We need to write 56 as a product of primes.

Prime Numbers:

<em>Numbers that are divisible by 1 or itself.</em>

Now, writing 56 as product of primes

56 = 2 x 2 x 2 x 7

Now, Use index notation when giving your answer.

Index Notation:

<em>Express elements in power form i.e. if we have 2 x 2 we can write it as 2^2</em>

So, answer will be:

$56 = 2 \times 2 \times 2 \times 7$

$=2^3 \times 7$

So, 56 as a product of primes using index notation is: $\mathbf{2^3 \times 7}$

Solve <br> (3x+4) (2x-1)=0 <br> X(4x+3)= 0

kotegsom [21]

Answer:

x = -4/3 x = 1/2

x=0 x = -3/4

Step-by-step explanation:

(3x+4) (2x-1)=0

Using the zero product property

3x+4 = 0 2x-1 =0

3x= -4 2x= 1

x = -4/3 x = 1/2

x (4x+3) =0

Using the zero product property

x = 0 4x+3 = 0

x=0 4x=-3

x=0 x = -3/4

A cylinder has a radius of 2.8 inches and a height of 2.4 inches. Which cylinder is similar?

Eddi Din [679]

If two figures are similar, the ratio of their corresponding sides are equal

Let us take the ratio of the radius to the height of the given cylinder. This gives us,

$\frac{radius}{height}=\frac{2.8}{2.4}$

In the simplest form, we have,

$\frac{radius}{height}=\frac{7}{6}$

Let us now find out which of the cylinders in the option has the same ratio,

For option A,

$\frac{radius}{height}=\frac{1.8}{1.4}$

In the simplest form, we have,

$\frac{radius}{height}=\frac{9}{7}$

For option B,

$\frac{radius}{height}=\frac{1.4}{1.2}$

In the simplest form, we have,

$\frac{radius}{height}=\frac{7}{6}$

For option C,

$\frac{radius}{height}=\frac{5.6}{4.2}$

In the simplest form, we have,

$\frac{radius}{height}=\frac{4}{3}$

For option D,

$\frac{radius}{height}=\frac{2.4}{2.8}$

In the simplest form, we have,

$\frac{radius}{height}=\frac{6}{7}$

<h2>Hence the correct answer is B</h2>
