Answer:

$8$

Step-by-step explanation:

$6t - 20 - 32u = 6(6) - 20 - 32( \frac{1}{4} ) = 36 - 20 - 8 = 16 - 8 = 8$

Hope this helps ;) ❤❤❤

Plug in the numbers. 6(6)-20-32(1/4)
Then multiply first. 36-20-8.
Then go left to right for subtracting.
36-20= 16; 16-8=8
So your answer would be 8.

Sveta_85 [38]

Answer: 12

Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

3. A submarine dives at an

Vesna [10]

Answer:

The height of deepness of submarine is 424.1 feet

Step-by-step explanation:

Given as :

The angle at which submarine drives of the surface of water = Ф = 13°

The speed at which submarine travel = s = 760 feet per minute

Let The height of deepness of submarine = h feet

The time taken to reach that deepness = t = 5 minutes

<u>According to question</u>

The height of deepness of submarine = $\dfrac{\textrm speed}{\textrm time}$

i.e h × cos(90 - Ф) = $\dfrac{s}{t}$

Or, h × Sin(Ф) = $\dfrac{\textrm 760 feet per min}{8 min}$

Or, h × Sin(13°) = 95 feet

Or, h × 0.224 = 95 feet

∴ h = $\dfrac{95}{0.224}$

i.e h = 424.10 feet

So, The height of deepness of submarine = h = 424.10 feet

Hence, The height of deepness of submarine is 424.1 feet Answer

I need first one and the second one please! I need it tomorrow!

I have a total of 11 pencils = total outcome
a- since we have 6 Red, P(Red)=6/11
b- P(Black) = 3/11
c- P(Green) = 1/11
For the dice:
Total outcome 6 so :
P(3) =1/6
P(1) =1/6
P(less than5) means P( of 1 OR 2 OR 3 Or 4)
Since we have "OR" it means we can add the P(probabilities)====>
P( of 1 OR 2 OR 3 Or 4)=1/6+1/6+1/6+1/6=
= 4/6 = 2/3
