Answer:

F. 824.8 ft³

Step-by-step explanation:

To find the volume of a cube, you want to multiply the length by width by height.

l = 8.2

w = 9.4

h = 10.7

l • w • h

8.2  • 9.4 • 10.7

= 824.756

Round to the nearest tenth.

824.8 ft³

Answer:

23.31 ft

Step-by-step explanation:

Reference angle = 47°

Opp = 25 ft

Adj = x

Apply trigonometry ratio TOA:

Tan 47 = Opp/Adj

Tan 47 = 25/x

x*Tan 47 = 25

x = 25/Tan 47

x = 23.3128772 ≈ 23.31 ft (to 2 d.p)

Answer:

Yellow= 1/2 or 50%chance

Red= 1/5 or 20% chance

Blue= 1/5 or 20% chance

Green= 1/10 or 10% chance

Step-by-step explanation:

There are 10 game pieces

5 are yellow

2 are red

2 are blue

And 1 is green

5/10=1/2=50%

2/10=1/5=20%

2/10=1/5=20%

1/10=10%

Add these up and you get 10/10 or 100%

Answer:

Step-by-step explanation:

Answer:

We have 4 triangles with base 3 and height 4 and a square with side length 3 so:

Triangles:

The area for a triangle is calculated by [tex]\frac{bh}{2}[/tex] where b is the base and h is the height so we have [tex]\frac{12}{2}\cdot 4[/tex] so we have a total area of 24.

[b]Square:[/b]

The area of a square is calculated by [tex]s^{2}[/tex] where s is the side length so we have the area is 9.

Now we put them together for the surface area so we get 24 + 9 = [tex]\boxed{33}[/tex]

Answer:

4.64

Step-by-step explanation:

If you do 20% of 1.45, you would get 0.29, add that by 1.45 plus 1.45 plus 1.45, and you get 4.64. Hope this helps!

Answer:

$4.64

Step-by-step explanation:

3 x 1.45 = 4.35

1.45 x .2 = .29

4.35 +.29 = 4.64

Answer:

Angle 6

Step-by-step explanation:

The opposite exterior angle to angle 3 is angle 6.

For another example, the opposite exterior to angle 1 is angle 8.

If you were to cut them out and put them over each other, they're congruent. Hope that helped you out :)

Answer:

Mr.Tuyen uses 3 1/8 tanks of gas in 5 weeks. The improper fraction version would be 25/8 if that is what you're looking for

Given:

Consider the below figure attaches with this question.

To find:

The size of angle x.

Solution:

Law of Cosines:

[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]

Three sides of the triangle are 11 cm, 8 cm, 15 cm. Since 11 cm is the opposite side of the angle x, therefore [tex]a=11[/tex].

Let [tex]A=x,a=11,b=8,c=15[/tex]. Substitute these values in the above formula.

[tex]\cos x=\dfrac{8^2+15^2-11^2}{2(8)(15)}[/tex]

[tex]\cos x=\dfrac{64+225-121}{240}[/tex]

[tex]\cos x=\dfrac{168}{240}[/tex]

[tex]\cos x=0.7[/tex]

Taking cos inverse on both sides, we get

[tex]x=\cos^{-1} 0.7[/tex]

[tex]x=45.572996^\circ[/tex]

[tex]x\approx 45.6^\circ[/tex]

Therefore, the measure of angle x is 45.6°.

Answer:

b. 156

Step-by-step explanation:

180 - 29 = 151

x-5=151

x=151+5

Answer:

x = 156

Step-by-step explanation:

A straight line has an angle of 180 degrees. Subtract the known angle from 180:

180 - 29 = 151

The missing angle is 151 degrees. The value of x is 5 more, given 151 = ( x - 5 ).

151 + 5 = 156.

x = 156.

Hope that helped :)

Answer:

I'm going to make an uneducated guess here.

I think the probability of two engines failing would be the same for either aircraft. In the instance that does happen, the helicopter doesn't fly at all and the airplane does.

I say the airplane is safer.

Step-by-step explanation:

So, the plane is safer than the helicopter.

The formula for finding the probability by Binomial distribution is,

[tex]P(X = x) = n_C_x \times p^x \times (1 - p)^{(n - x)}[/tex]

For Helicopter,

We need to calculate, Probability of safe landing, [tex]P(X = 0)[/tex]

Here, [tex]n = 2, p = 0.99, (1 - p) = 0.01\ and\ x = 1[/tex]

As per binomial distribution formula [tex]P(X = x) = n_C_x \times p^x \times (1 - p)^{(n - x)}[/tex]

We need to calculate [tex]P(X \ge 1).[/tex]

[tex]P(X \ge1) = (2_C_1 \times 0.99^1 \times 0.01^1) + (2_C_2 \times 0.99^2 \times 0.01^0)\\P(X \ge1) = 0.0198 + 0.9801\\P(X \ge 1) = 0.9999[/tex]

For Plane,[tex]P(safe\ landing)[/tex]

Here, [tex]n = 4, p = 0.99, (1 - p) = 0.01\ and\ x = 2[/tex]

As per binomial distribution formula [tex]P(X = x) = n_C_x \times p^x \times (1 - p)^{(n - x)}[/tex]

We need to calculate P(X >= 2).

[tex]P(X \ge 2) = (4_C_2 \times 0.99^2 \times 0.01^2) + (4_C_3 \times 0.99^3 \times 0.01^1) + (4_C_4 \times 0.99^4 \times 0.01^0)\\P(X \ge 2) = 0.0006 + 0.0388 + 0.9606\\P(X \ge2) = 1\\[/tex]
