A cone with a radius of 7ft and a height of 12ft is filled with wet sand. you took that sand and built a pyramid with a base of 4ft by 5ft how tall would the resulting pyramid be?

Answers

Answer 1

Answer:

95.36 ft

Step-by-step explanation:

Volume of a Cone[tex]=\frac{1}{3}\pi r^2 h[/tex]

Radius=7 ft, Height=12 ft

Therefore the volume of sand in the cone

[tex]=\frac{1}{3}\pi *7^2*12\\=615.7522$ ft^2[/tex]

If the sand was used to build as pyramid with a base of 4ft by 5ft.

Volume of a Pyramid[tex]=\frac{1}{3}*$Base Area* Height[/tex]

[tex]615.7522=\frac{1}{3}*(4*5)* Height\\615.7522=\dfrac{20}{3}* Height\\$Multiply both sides by \dfrac{3}{20}\\$Height =615.7522*\dfrac{3}{20}\\\\$Height of the pyramid=95.36 ft[/tex]

Answers

It’s D) because 7.38x9 is 66.42

Answer:

D. $66.42

Step-by-step explanation:

If I'm correct (which I highly doubt...)

You multiply 7.38 and 9

That should give $66.42

Sorry if I'm wrong...

And if I'm wrong, my second option would be C. $0.82

2.state the measure of angle 5 and how you know

Thank you!

Answers

Answer:

1. No, Joe is not correct

2. [tex]\angle 5=72^{\circ}[/tex]

Step-by-step explanation:

Given: b and c are parallel lines

To find:

1. whether the given statement is correct or not

2. [tex]\angle 5[/tex]

Solution:

1.

Sum of two angles that form a linear pair is equal to [tex]180^{\circ}[/tex]

[tex]\angle 3+72^{\circ}=180^{\circ}[/tex] (linear pair)

[tex]\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}[/tex]

So, Joe is not correct

2.

If two lines are parallel then alternate interior angles are equal.

As b and c are parallel lines,

[tex]\angle 5=72^{\circ}[/tex] (alternate interior angles)

what are the solutions of 2x^2 +16+34=0?

Answers

Answer:

5i, and - 5i ⇒ ± 5i

Step-by-step explanation:

We are given the equation 2x^2 + 16 + 34 = 0;

2x^2 + 16 + 34 = 0 ⇒ subtract ( 16 + 34 ) from either side of equation,

2x^2 = - 50 ⇒ divide either side by 2,

x^2 = - 25 ⇒ take square root on either side of equation,

| x | = √ - 25 ⇒ apply imaginary value i,

± 5i, provided absolute value sign | |;

Solution; ± 5i

Answers

Answer:

4% account - $1500

4.75% account - $3000

Step-by-step explanation:

x = amount of money in the account that pays 4% interest

y = amount of money in the account that pays 4.75% interest

x + y = 4500

0.04x + 0.0475y = 202.50

4x + 4y = 18000

4x + 4.75y = 20250

  4x + 4y = 18000

- (4x + 4.75y = 20250)

= -0.75y = -2250

y = 3000

x + 3000 = 4500

x = 1500

Solve: -2 < x + 3 < 5

Answers

Answer:

The answer is

[tex] - 5 < x < 2[/tex]

Step-by-step explanation:

First you have to seperate them :

[tex] - 2 < x + 3[/tex]

[tex]x + 3 < 5[/tex]

Next you can solve it by moving all the unrelated terms to the other side :

[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]

[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]

Answer:

-5 < x < 2

Step-by-step explanation:

Subtract 3 from each of the three sides.

-2 < x + 3 < 5

-2 - 3 < x + 3 - 3 < 5 - 3

-5 < x < 2

What's the eleventh term of a sequence with an explicit rule of ƒ(n) = 2 + 3(n – 1)?

Question 16 options:


A)


ƒ(11) = –31


B)


ƒ(11) = 32


C)


ƒ(11) = 23


D)


ƒ(11) = –22

Answers

Answer:

B. F(11) = 32

Step-by-step explanation:

From the explicit equation,

F(n) = 2 + 3(n - 1)

F(11) = 2 + 3(11 - 1)

F(11) = 2 + 33 - 3

F(11) = 35 - 3

F(11) = 32

The 11th term of the sequence with an explicit rule is 32

We simplify the equation to the form, which is simple to understand  

51-2z-8z=23

We move all terms containing z to the left and all other terms to the right.  

-2z-8z=+23-51

We simplify left and right side of the equation.  

-10z=-28

We divide both sides of the equation by -10 to get z.

Step-by-step explanation:

The point slope form of the equation is

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y - -6 = 7/3( x -1)

y+6 = 7/3(x-1)

Answer:

D

Step-by-step explanation:

The general form of a line in point-slope form is y-k=m(x-h), where k is the y coordinate any point on the line, h is the x coordinate, and m is the slope of the line. Therefore, the equation of this line would be y+6=7/3(x-1), or choice D. Hope this helps!
