The equation 12+3x=30 can be solved by the following

12+3x=30

First subtract 12 from both sides making the equation

3x=18

Now divide 3 from both sides

x=6

The given numbers ordered from least to greatest is:

{√7 , 2.8..., π, √17, 4.6}

<h3>How to order the numbers from least to greatest?</h3>

First, we need to write all the given numbers in decimal form so we can accurately compare them.

The numbers are:

{4.6, √7, π, 2.8..., √17}

Rewriting all of these in decimal form:

√7 = 2.64

π = 3.14159265....

√17 = 4.12

Then the numbers are:

{4.6, 2.64, 3.14159265...., 2.8..., 4.12}

Now is easier to order these numbers, ordering them from least to greatest we will get:

{2.64, 2.8..., 3.14159265...., 4.12, 4.6}

Now, using the original notation we get:

{√7 , 2.8..., π, √17, 4.6}

Please help me with this trigonometry question:

zzz [600]

Answer:

The distance from A to B is 736.2 to the nearest tenth foot

Step-by-step explanation:

In ΔCAB

∵ m∠CAD = 30° ⇒ exterior angle of Δ at vertex A

∴ m∠CAD = m∠ACB + m∠ABC

∵ m∠ABC = 20°

∴ m∠ACB = 30° - 20° = 10°

We will use the sin rule to find the distance AB

∵ $\frac{sin20}{1450}=\frac{sin10}{AB}$

∴ $AB=\frac{1450(sin10)}{sin20}=736.1842936$ ≅ 736.2 to the nearest tenth foot

Yesterday, 12 kids played Among Us and 8 kids did

marysya [2.9K]

Answer:

60%

Step-by-step explanation:

12 kids played. 8 didn't play. That means there is a total of 20 students.

The fraction would be 12/20.

To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)

100 divided by 20 is 5

12 x 5 = 60

sweet-ann [11.9K]

Answer:

3731.2 pounds

Step-by-step explanation:

Aquarium will hold 4.4 * 2.5 * 5.3 = 58.3 cubic feet of sea water.

For 3 cubic feet of sea water, weight is 192 pounds

For 58.3 cubic feet of sea water,

( 192 * 58.3) / 3 = 11193.6 / 3 = 3731.2 pounds
