In six seconds,a total of 3 waves crash onto the shore of the beach .

The distance between each wave crest on the water is 8 meters.

Wave length is the length between two wave crests that is the distance between two wave crests.

We know distance between each wave crest is 8 meters

Total of 3 wave crests, the distance between first and second wave crest is 8 meters

the distance between second and third wave crest is 8 meters

So wave length = 8+8 = 16 meters

Estimate the total weight of two boxes that weigh 9.4 and 62.6 pounds using rounding and compatible numbers. which estimate is c

Anit [1.1K]

With rounding:
$4$ is less than $5$ so we round it down to whole number:
$9.4\approx9$

$6$ is more than $5$ so we round it up to whole number:
$62.6\approx63$

Now we have to add rounded numbers
$63+9=72$

Without rounding:
$62.6+9.4$ to make it more visible I will write it differently:

$62+9+0.6+0.4$ is equal to $62.6+9.4$

we can see that $0.6+0.4$ is equal to $1$

so:
$62+9+1=72$

<span>As you see in this example those equations are equal so it doesn't matter if you take rounded numbers or not, it may be different in case like $62.4+9.4$ ( $0.4$ is just an example it could be any other number between $0-4$ ) because in this case it will be equal $71$ and another example $62.5+9.5$ (in this case $0.5$ is just an example, it can be any other number between $5-9$ :) ) and here, answer for this equation is $73$ .</span>

Step-by-step explanation:

Increase = 30 000 × 0.112

Increase = $3336

New salary = 30 000 + 3336

New salary = $33 336

The value of the variable x will be 37°. Then the measure of the angle ∠QNP will be 105°.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The measure of angles ∠MNQ = (2x + 1)° and ∠QNP = (3x - 6)°.

Then the value of x will be

We know that the angles ∠MNQ and ∠QNP are supplementary angles. Then the value of the variable x will be

∠MNQ + ∠QNP = 180°

(2x + 1)° + (3x - 6)° = 180°

5x - 5° = 180°

5x = 185°

x = 37°

Then the measure of the angle ∠QNP will be

∠QNP = [3(37) - 6]°

∠QNP = 111° - 6°

∠QNP = 105°

The value of the variable x will be 37°. Then the measure of the angle ∠QNP will be 105°.
