Approximate square root 18 to the tenths and plot on number line

1 answer:

8 0

Since 18 does not have a number that when multiplied by itself equal 18, then it will be a decimal number. You can tell the closest whole number by seeing what is the closest square. In this case we know that 16 is 4 times 4 and the next one would be 5 times 5 to equal 25, so the whole number would be 4.

Now, the easiest way to do this is to get you calculator and take the square root of 18 to get 4.242641. The problem wants it to be to the nearest tenth so 4.2 is your answer. On a number line, if it is in four parts, you will plot it just before the first little line.

Hope this helps! If you are using more small lines in you number line, comment me below and I would be happy to lead you in the right direction.

Show how to solve the problem 378 x 6 using place value with regrouping. Explain how you knew when to regroup.

KIM [24]

<u>Answer</u>

2,268

<u>Explanation</u>

<u>By grouping 378 ca</u>n be written as,

378 = 300 + 70 + 8

6× 378 = 6 × (300 + 70 + 8)

= (6×300) + (6×70) + (6×8)

= 1800 + 420 + 48

= 2,268

In the figure, line m is parallel to line n. The measure of angle 2 is 40 degrees and the measure of angle 3 is 68 degrees. What

sveticcg [70]

Answer:

∠1 - 40°

Step-by-step explanation:

∠1 - 40°

b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.

∠2 - 140°

b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.

∠3 - 40°

b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.

∠4 -

b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.

∠5 - 35°

b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

hope that helps lol >:)

When h is one-half and j is one-third, g is 4. if g varies jointly with h and j, what is the value of g when h is 2 and j is 3?

Effectus [21]

The value of g = 144 solved by using direct proportion.

<h3>What is a direct proportion?</h3>

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝.

Given that,

h = $\frac{1}{2}$ , j = $\frac{1}{3}$ , g = 4
