0.002 is 1/10 (fraction) of......
Tpy6a [65]
<span>0.002 is the 1/10 of what number.
Find the number that applies to this.
=> 0.002 has a thousandths value since it is placed next to the decimal points
=> To be able to get the answer. Let’s convert 1/10 into a decimal.
=> 1 / 10 = 0.1
Now that we have the same decimal numbers, we can now start dividing 0.1 to 0.002
=> 0.002 / 0.1
=> 0.02
Thus, 0.002 is the 1/10 of 0.02 number.</span><span>

An airplane climbs at an angle of 16° with the ground. Find the ground
Tatiana [17]

Answer:

2403.2

Step-by-step explanation:

We get the length of the hypotenuse, and the base angle. To find the length of the base, we use the cosine of 16° since it is equal to the adjacent side length/ hypotenuse side length or cos 16°= x/2500. The isolate x by multiplying both sides by 2500. The cos 16° is around 0.96126, multiplied by 2500 (cos 16°(2500)) = 2403.1

(2x - 3y)(4x - y) can you help me
Mnenie [13.5K]

Answer:

<h2>(2x - 3y)(4x - y) = 8x² - 14xy + 3y²</h2>

Step-by-step explanation:

Use FOIL:  <em>(a + b)(c + d) = ac + ad + bc + bd</em>

(2x - 3y)(4x - y) = (2x)(4x) + (2x)(-y) + (-3y)(4x) + (-3y)(-y)

= 8x² - 2xy - 12xy + 3y²

<em>combine like terms</em>

= 8x² + (-2xy - 12xy) + 3y² = 8x² - 14xy + 3y²

Please help with this question ASAP!
Naddik [55]

Answer:

8w : 3.8974342 ≈ 3.9 or 4 (hope it help)

Step-by-step explanation:

1w : 2

2w : 2 + 10% = 2.2

3w : 2.2 + 10% = 2.42

4w : 2.42 + 10% = 2.662

5w : 2.662 + 10% = 2.9282

6w : 2.9282 + 10% = 3.22102

7w : 3.22102 + 10% = 3.543122

8w : 3.543122 + 10% = 3.8974342

3.8974342 ≈ 3.9 or 4
