Work Shown:

The cylinder has volume of...

V = pi*r^2*h

V = 3.14*4^2*8

V = 401.92

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

The rectangular prism has a volume of...

V = L*W*H

V = 10*7*6

V = 420

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

Subtract the two results:

420-401.92 = 18.08

The cylinder has roughly 18.08 more cubic units of volume compared to the rectangular prism.

Answer:

volume of cylinder: V=Sđ*h=R^2*3.14*8

volume of rectangular prism: V=Sđ*h=10*7*6

Answer:

13

Step-by-step explanation:

To find the range substitute the value of x from the domain into the equation.

x = - 2 : y = -5(- 2) + 3 = 10 + 3 = 13

x = 0 : y = - 5(0) + 3 = 0 + 3 = 3

x = 1 : y = - 5(1) + 3 = - 5 + 3 = - 2

x = 3 : y = - 5(3) + 3 = - 15 + 3 = - 12

range is { - 12, - 2, 3, 13 }

with greatest value in the range being 13

Answer:

x=2

Step-by-step explanation:

15x-10=20

+10 to both sides

15x=30

divide both sides by 15

x=2

Answer:

x = 2

Step-by-step explanation:

15 x - 10 = 20

15 times 2 = 30

30 -10 = 20

20 = 20

So x equals 2

5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.

A pattern is a sequence. It can be an AP, GP also.

present ratio between number of straight lines and number of arcs

=8:9

When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.

Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.

Hence 5 rows are to be added in the pattern B to get the ratio 7:6.

Answer:

3rd one

Step-by-step explanation:

Answer:

k - 2 = 4d - 8

d + 1 = 4d - 8

Step-by-step explanation:

Daniel's age = d

Kevin's age = k

Given that, k = d + 3 -------------- (1)

Two years ago, the age of Daniel = d - 2

Two years ago, the age of Kevin = k - 2

Since,  two years ago, Kevin was 4 times as old as

Daniel, k - 2 = 4(d - 2)

Opening the bracket,

k - 2 = 4d - 8

Since the value of k is d + 3 (see (1))

d + 3 - 2 = 4d - 8

d + 1 = 4d - 8

(I am just giving the answer cause I LOVE Linear Equation )

1 + 8 = 4d - d

9 = 3d

9/3 = d

3 = d

Therefore, Daniel's present age is 3 and Kevin's present age = 6

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".

Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.

Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3

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

To summarize so far, we have these three facts

in this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.

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

Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.

It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

Answer:

1773.91 miles

Step-by-step explanation:

Given data

Completed miles= 816 miles

Percentage completion= 46%

Let the total distance be x

Hence

46% of x= 816

let us find x

46/100*x= 816

0.46x=816

x= 816/0.46

x= 1773.91

Therefore the total distance is 1773.91 miles

Answer:

j = 15

Step-by-step explanation:

The angles shown form a straight line

Angles on a straight line must add up to 180 degrees

Hence, 2j + 32 + 6j - 2 + 30 = 180

( note that we just created an equation that we can use to solve for j )

We now solve for j using the equation we created.

2j + 32 + 6j - 2 + 30 = 180

step 1 combine like terms

2j + 6j = 8j

32 - 2 + 30 = 60

we now have 180 = 8j + 60

step 2 subtract 60 from each side

60 - 60 cancels out

180 - 60 = 120

we now have 120 = 8j

step 3 divide each side by 8

120 / 8 = 15

8j / 8 = j

we're left with j = 15

Answer:

The value of the coin tosses per time in the air

Step-by-step explanation:

The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The theoretical probability of tossing tails in a fair coin is 0.5 or 1/2.

The experimental probability of tossing tails in n trials is the number of times tails appear divided by n.

So, we want to find a value of n such that:

number of times tails appear / n = 0.5

Solving for n:

number of times tails appear = 0.5n

Since the number of times tails appear must be a whole number, n must be even.

This is because if n is odd, then it is not possible to have exactly half the trials result in tails.

For example,

If n=3, the possible numbers of tails that can appear are 0, 1, 2, or 3. Half of 3 is 1.5, which is not a whole number, so it is impossible to have exactly half the trials result in tails.

On the other hand,

If n=4, the possible numbers of tails that can appear are 0, 1, 2, 3, or 4.

Half of 4 is 2, which is a whole number, so it is possible to have exactly half the trials result in tails.

Therefore,

The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.
