to the nearest tenth with a

diameter of 2 ft and a height

of 8 ft:)

Answer 2

Answer:

33.493

Step-by-step explanation:

to find the volume of a cone the equation that you are going to use is:

[tex]V=\pi r^2 \frac{h}{3}[/tex]

Step 1: Plugin

[tex]V=\pi 2^2 \frac{8}{3}[/tex]

r/Diameter=2

h=8

step 2: solve

[tex]\pi =3.14[/tex]

[tex]2^2=4[/tex]

[tex]3.14 x 4x \frac{8}{3} = 33.49[/tex]

Rewrite the equation in slope-intercept form.

x - 19y = 4

Answers

Answer:

[tex]y = \frac{1}{19} x - \frac{4}{19} [/tex]

Step-by-step explanation:

[tex]x - 19y = 4[/tex]

Slope intercept form :

y= mx+b

Where ;

m = slope

b = intercept

[tex] - 19y = - x + 4[/tex]

Divide through by -19

[tex] \frac{ - 19y}{ - 19} = - \frac{x}{ - 19} + \frac{4}{ - 19} [/tex]

Simplify

[tex]y = \frac{1}{19} x - \frac{4}{19} [/tex]

Answer:

y = (1/19)x - (4/19)

Step-by-step explanation:

x-19y=4

19=m(slope) write it as 1/19

write 4 as 4/19(represents b or y-intercept)

y=mx+b

m=(1/19)

b=(4/19)

Plug in those numbers into the equation to get: y = (1/19)x - (4/19)

∠A and \angle B∠B are vertical angles. If m\angle A=(3x-21)^{\circ}∠A=(3x−21) ∘ and m\angle B=(2x-13)^{\circ}∠B=(2x−13) ∘ , then find the value of x

Answers

Answer:  x = 8

===============================================

Work Shown:

Vertical angles are always congruent

(angle A) = (angle B)

(3x-21) = (2x-13)

3x-21 = 2x-13

3x-2x = -13+21

x = 8

---------

Extra info:

Use this x value to find each angle

angle A = 3x-21

angle A = 3*8-21

angle A = 24-21

angle A = 3 degrees

angle B = 2x-13

angle B = 2*8-13

angle B = 16-13

angle B = 3 degrees

Both angles A and B are 3 degrees, so this confirms the answer.

Both the angles A and B are 3 degrees, so this confirms that both are vertical angles.

What are vertical angles?

Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.

The Vertical angles are always congruent,

(angle A) = (angle B)

(3x-21) = (2x-13)

3x-21 = 2x-13

3x-2x = -13+21

x = 8

Now Use this x value to find each angle;

angle A = 3x-21

angle A = 3*8-21

angle A = 24-21

angle A = 3 degrees

angle B = 2x-13

angle B = 2*8-13

angle B = 16-13

angle B = 3 degrees

Hence Both the angles A and B are 3 degrees, so this confirms that both are vertical angles.

Describe how you can use the factors of a quadratic function to find its zeros.

Answers

Answer:

Factorising the equation into brackets can help you identify where the x-intercepts are (where the function cuts the x-axis)

Step-by-step explanation:

When you factorise the equation it would look something like this:

(x + a)(x + b) = 0

This also means:

x + a = 0        and        x + b = 0

x = -a             and        x = -b

Example:

Find where the function y = 2x² + 8x + 6 cuts the x-axis

What is subtraction?

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

A certain book is for sale in both Belize and Brazil.

In Belize, it sells for 80.39 Belize dollars.

The exchange rate of us dollars to Belize dollars is 1:1.9246

The cost of a book in dollars will be

[tex]\rm \dfrac{C_{belize }}{80.39} = \dfrac{1}{1.9246}\\\\C _{belize } \ = 41.7697[/tex]

In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of us dollars to Brazilian reals is 1:1.7880.

The cost of a book in dollars will be

[tex]\rm \dfrac{C_{brazil}}{63.65} = \dfrac{1}{1.778}\\\\C _{brazil} \ = 35.5984[/tex]

The difference in the cost will be

[tex]\rm C _{belize} -C _{brazil} = 41.7697 - 35.5984 = 6.1713 \approx 6.17[/tex]

8. PROM A limo costs $85 to rent for 3 hours plus a 7% sales tax, What is the total cost
to rent a limo for 6 hours?

Answers

Answer:

181.9 dollars

Step-by-step explanation:

If it costs 85 dollars for 3 hours we want to double that to get the amount for 6 hours which is 170 dollars. This is before sales tax. You can find the amount after sales tax by multiplying 170 by 1.07. You do this because 100 percent of the cost would be 170 times 1, and 7 percent is .07, so if you want 107 percent of the cost you want to do 170 times 1.07. This works because it takes 7 percent of 170 and adds it to the total cost. You could also do this by 170 times .07. Then add the product to 170. 181.9 is the final answer.

Write the converse of the following statement and determine its truth value:

for brainliest

Answers

Answer:

The converse is:

if the ratio of lefties to righties is 1 : 8, then for every 3 left handed people, there are 24 right handed people.

The truth value is:

True

Step-by-step explanation:

The statement can be split into:

p -> If a class has 3 left-handed people and 24 right-handed people,

q -> the ratio of lefties to righties is 1:8

The converse of a conditional statement is:

if q then p

So, we have the converse to be;

if the ratio of lefties to righties is 1 : 8, then for every 3 left handed people, there are 24 right handed people.

The truth value.

For p, we have.

Ratio = 3 : 24

This can be simplified to.

Ratio = 1 : 8

For q, we have:

Ratio = 1 : 8

Since both are true, then the truth value is true

As it emerges from the cross multiplication performed, the statement is correct.

Since it is stated that "If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1: 8", to determine if this statement is correct the following calculation must be performed:

1 = 3 8 = X 8 x 3 = X 24 = X

Therefore, as it emerges from the cross multiplication performed, the statement is correct.
