Find the volume of the cone. Round to the nearest tenth.
2 ft. 14ft
Volume: ft3

Answer:

791.7 in.²

Step-by-step explanation:

Surface area of the composite figure = ½(surface area of sphere) + surface area of cylinder

= ½(4πr²) + (2πr(h + r)

Where,

r = ½(12) = 6 in.

h = 9 in.

SA = ½(4*π*6²) + (2*π*6(9 + 6)

SA = ½(452.39) + 565.49

SA = 791.685

SA = 791.7 in.² (nearest tenth)

Answer:

x=2/5, y=-24/5. (2/5, -24/5).

Step-by-step explanation:

y=-2x-4

y=1/2x-5

----------------

-2x-4=1/2x-5

-2x-1/2x-4=-5

-4/2x-1/2x=-5+4

-5/2x=-1

5/2x=1

x=1/(5/2)

x=2/5

y=1/2(2/5)-5

y=1/5-5

y=1/5-25/5

y=-24/5

Answer:

B. 273

Step-by-step explanation:

First we have to find the volume of the pencil box.

The volume formula for a rectangular prism is lwh (Length x width x height). Length (6 1/2) x Width (3 1/2) x Height (1 1/2) = 34.125 (Volume of the pencil box)

Next, we have to find the volume of the cube.

The volume formula of a cube is the same as the volume formula for a rectangular prism (lwh). However, a cube's side lengths are all the same. This means that the volume of the cube would be Length (.5) x Width (.5) x Height (.5) = .125

Last, we have to divide the volume of the pencil box by the volume of the cube.

34.125 / .125 = 273 or B.

Answer:

77 1/3

Step-by-step explanation:

to get x you have to divide both sides by 36

2784=36x

x=77 1/3

you can also use an algebra calculator for it

Answer:

77.333

Step-by-step explanation:

So we are given the equation

2784 = 36x

But we need to find the value of just x. So if 36 x = 2784:

2784/36 = x

How did we do this? Well, we divided each side of the equation by 36, which gives us the amazing value of just x.

Solve the equation

77.333 = x

Now, lets check our work:

77.333 x 36 = 2783.88

This is the closest I believe we can get.

Hope this helps!

Answer:

11.5 square units

Step-by-step explanation:

It’s a 4 by 6 rectangle, so the total is 24.  Then subtract the three little triangles on the outside.  (Much easier than doing the main triangle).

1/2x1x4=2

1/2x1x6=3

1/2x3x5=7.5

2+3+7.5=12.5

24-12.5=11.5

Answer:

132cm ^ 2

Step-by-step explanation:

First solve the top rectangle, 4x7 = 28cm

then solve the bottom rectangle, 8x7 = 56cm

then solve the triangle, we know the entire bottom is 19cm, and 7 is subtracted, thereforth leavin 12, since there is 2 triangles its a base of 6, with a height of 8 making 48cm (and since there is 2 triangles no need to divide by 2)

28+56+48 = 132cm^2

Answer:

15: 58 degrees. 16: Answer D

Step-by-step explanation:

Question 15

All you have to do for this one is to add the angle measures of 22 and 36 degrees together to get the answer of 58 degrees.

Question 16

The interior angles of a triangle will always add up to 180 degrees.

Therefore, 180 - 53 - 21 is the answer, which totals 106 degrees.

Answer:

We reject H₀ . We found that at significance level of 0,05 the mean of the type 2 rope is greater than that of rope 1

Step-by-step explanation:

Type 1 rope information:

x₁  =  6.2888

s₁  = 0.1352

n₁  =  17

Type 2 rope Information:

x₂  = 6.400

s₂  = 0.1070

n₂  = 14

We don´t know population standard deviation

We assume that populations follow normal distribution

Hypothesis Test:

Null Hypothesis                               H₀                 x₂  =  x₁

Alternative Hypothesis                    Hₐ                 x₂  >  x₁

The alternative hypothesis indicates a one-tail test on the right

Significance level α  =  0,05     confidence Interval  95 %

Degrees of freedom for t(c)   is   n₁  +  n₂  - 2  =  17 + 14 - 2  

df  =  31 - 2    df  =  29

Then from t- student table we get  t(c)  =  2,045

To calculate t(s)

t(s) =  (   x₂  -   x₁  ) / sp √ ( 1/n₁  +  1/n₂

Doing calculations:

√ (1/n₁  +  1/n₂    =  √  1/17  + 1/14  =   √  0,0588 + 0,0714  = √ 0,1302

√ (1/n₁  +  1/n₂    =  0,3608

sp²  =  ( n₁ - 1 )* s₁²  +  ( n₂ - 1 )*s₂² / n₁ + n₂ - 2

sp²  =  16* (0,1352)²  +  13* ( 0,1070)²  / 29

sp²  =  16*0,0183  +  13* 0,0114 / 29    =    0,2928 + 0,1482 / 29

sp²  =  0,01520

sp  =  0,1233

By substitution

t(s)  =  (  6,400  - 6,2888 ) / 0,1233*0,3608

t(s)  =  0,1112 / 0,0444

t(s) = 2,5045

Comparing  t(s)  and t(c)

t(s) > t(c)         2,50  >  2,045

Then t(s) is in the rejection region we reject H₀ . We found differences between the means of the two groups.

2.  [tex]\frac{1}{5} x + \frac{1}{3} + \frac{2}{5} x = \frac{3}{5} x + \frac{1}{3}[/tex]

Answer:

[tex]F=\frac{32\sqrt{3}}{3}\text{\:or\:} \approx 18.48\:\text{N}[/tex]

Step-by-step explanation:

We can find the horizontal component of force he applied by using the formula for work:

[tex]W=F\Delta x[/tex]

Solving for force, we have:

[tex]160=F\cdot 10,\\F=16\:\text{N}[/tex]

However he applied the original force at an angle of [tex]30^{\circ}[/tex] to the horizontal. This force of 16 newtons is only the horizontal component of that force. To find the magnitude of the original force, we can use basic trigonometry:

[tex]\cos 30^{\circ}=\frac{16}{x},\\x=\frac{16}{\cos 30^{\circ}},\\\\x=\frac{16}{\frac{\sqrt{3}}{2}},\\\\x=16\cdot\frac{2}{\sqrt{3}}=\frac{32}{\sqrt{3}}=\boxed{\frac{32\sqrt{3}}{3}}[/tex]

Answer:

[tex]Lower\ Bound = 6.65cm[/tex]

Step-by-step explanation:

Required

The lower bound

The lengths are approximately 6.7cm to 2sf are:

[tex]Length = \{6.65 \to 6.74\}[/tex]

Such that:

[tex]Length = \{Lower\ Bound \to Upper\ Bound\}[/tex]

So, by comparison:

[tex]Lower\ Bound = 6.65cm[/tex]

Answer:

P(B) = 8/12

P(R | B) = 4/11

P(B ∩ R) = 8/33

The probability that the first ball chosen is black and the second ball chosen is red is about  24 percent.

Step-by-step explanation:

I just got it right on edge 2020. Good luck with school!!

The probability that the first ball chosen is black and the second ball chosen is red is about percent is 66.67%.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a box contains four red balls and eight black balls.

Let event B be choosing a black ball first and event R be choosing a red ball second.

Here, total number of outcomes = 4+8 =12

P(B) = 8/12 and P(R)=4/12

We know that, P(R|B) =P(R∩B)/P(B)

Here, P(R∩B)= 8/12 × 4/12

= 2/3 × 1/3

= 2/9

So, P(R|B) =2/9 × 12/4

= 2/3 ×100

= 66.67%

Therefore, the probability that the first ball chosen is black and the second ball chosen is red is about percent is 66.67%.

Answer:

$38,562.5

Step-by-step explanation

Using the compound interest formula

A = P(1+r/n)^nt

P is the principal = $125,000

r is the rate = 6% = 0.06

time t  = 5years

n = 0.25 (quarterly payment)

Substitute

A = 125000(1+0.06/0.25)^5(0.25)

A = 125000(1+ 0.24)^1.25

A = 125000(1.24)^1.25

A = 125000(1.3085)

A = 163,562.5

Hence the interest earned = 163,562.5 - 125000

interest earned = $38,562.5

Answer:

To find solutions to an equation, we can choose any values for x, and then use the equation to find the value of y to make an ordered pair in the form (x,y). First, let's choose x = 1. y = 3(1) + 4 = 7 The ordered pair is (1,7) Let's choose x = 4. y = 3(4) + 4 = 16 The ordered pair is (4,16) Let's choose x = 11 y = 3(11) + 4 = 37 The ordered pair is (11,37) The three solutions we found are: (1,7) (4,16) (11,37) Note that we could choose any values for x that we like. In this case we chose x = 1, x = 4, and x = 11, but any values of x will work fine.

Answer:

x = 40

Step-by-step explanation:

So a triangle is 180 degrees

and thats a right triangle = 90 degrees

you have three corners: 90, 50 & x

90 + 50 + x = 180

140 + x = 180

subtract 140 from both sides

x = 40

hope this helps

Answer:

40 is the asnwer

Step-by-step explanation:

1. Well, first of all we know that all right angles add up to 180 degrees. The degrees shown in the picture are 50, and 90. You can’t see the 90 exactly, but you can tell by that little square, that’s how it shows us!

2. Second step, we add up 60 and 90 which is 140. We got that, now we can subtract this 140 to the 180 to get our answer!

3. 180 – 140 is equal to 40!

4. Therefore, the 3rd angle is 40!

5. Not confident with my ansawer? Proof time!

6. 40 + 50 + 90 = 180

7. Since this all adds up to 180, it is true!

Have a great day!
