Answer:

3(27) = 3(25 + 2) = TURE

Step-by-step explanation:

Left side: Use long multiplication:

| | 3

× | 2 | 7

Multiply 7 by the digit in the top row:

| | 3

× | 2 | 7

| 2 | 1

Multiply 2 by the digit in the top row:

| | 3

× | 2 | 7

| 2 | 1

| 6 | 0

Add:

Answer: 81

Right Hand: Simplify the following:

3 (25 + 2)

Hint: | Evaluate 25 + 2.

25 + 2 = 27:

3×27

Hint: | Multiply 3 and 27 together.

3×27 = 81:

pllllllls I need help right triangle and trigonometry special right triangles find the value of each variable

$\huge {\mathfrak{Answer : }}$

we know,

$\boxed{\cos( \theta) = \dfrac{base}{hypotenuse}}$

so,

$\cos(30) = \dfrac{24}{x}$

$\dfrac{ \sqrt{3} }{2} = \dfrac{24}{x}$

$x = \dfrac{24 \times 2}{ \sqrt{3} }$

$x = 8 \sqrt{3} \times 2$

$x = 16 \sqrt{3}$

now,

$\boxed{ \tan( \theta) = \frac{perpendcular}{base} }$

$\tan(30) = \dfrac{y}{24}$

$\dfrac{1}{ \sqrt{3} } = \dfrac{y}{24}$

$y = \dfrac{24}{ \sqrt{3} }$

$y = 8 \sqrt{3}$

Do you think that science is a waste of time?

Gnoma [55]

Answer:

it can be. It just depends on what you are interested in. If you are interested in a scientific field then it is an amazing way to use your time. But if you are bot interested in science, it is a waste personally.
