In each empty table square, fill in the value that is computed by replacing 'n' in the rule to the left with the value of 'n' above that square.

For example:

The upper left empty square will be filled with ...

  n -5 . . . . with n replaced by 1

  1 - 5 = -4 . . . . the value that goes in the upper left square.

__

Another example:

The lower right square will be filled with ...

  4n -3 . . . . with n replaced by 100

  4·100 -3 = 400 -3 = 397 . . . . the value that goes in the lower right square

Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, and mesurments of angle B=30 degrees.

Answers

Answer:

<D = 100

<E =30

<F =50

Step-by-step explanation

Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e

<A = <D

<B = <E

<C = <F

Given

<A = 100 then <D = 100

<B = 30°, then <E = 30°

To get <F, we will use the expression

<D+<E+<F = 180 (sum of angles in a triangle is 180°)

100+30+<F = 180

130+<F = 180

<F = 180-130

<F = 50°

Hence the measure of <F is 50°

For lines a , c , and d , line c is parallel to line d and m ∠ 1 = 55 ° . Part A: For the given diagram, use the measure of ∠ 1 to find the measure of the remaining seven angles. Part B: In two or more complete sentences, explain the relationship between angle pairs a) ∠ 1 and ∠ 7 and b) ∠ 1 and ∠ 2 . in your explanation, include how you calculated each of the angle measures in the special angle pairs.

Answers

Answer:

Part A:

1, 4, 5, and 8 = 55 degrees.

3, 2, 6, and 7 = 125 degrees.

Part B:

I know that angle 1 is 55 degrees so angle 7 would be 125.

I know that angle 1 is 55 and to get angle 2, both angles should add up to 180 so 180 - 55 is 125, that is how I find angle 2 = 125 degrees.

Step-by-step explanation:

This is what I wrote, I hope it helps and tell me if I am wrong but I think it is right.

Have a Meowgical day!

Part A:

The values of the angles are:

∠1 = 55

∠2 = 125

∠3 = 125

∠4 = 55

∠5 = 55

∠6 = 125

∠7 = 125

∠8 = 55

Part B:

∠1 and ∠7 are exterior angles on the same side.

∠1 and ∠2 form a straight angle.

We have,

Part A:

From the figure,

∠1 and ∠5 are corresponding angles.

So,

∠1 = ∠5 = 55

And,

∠1 and ∠8 are alternate exterior angles.

∠1 = ∠8 = 55

And,

∠1 and ∠4 are vertical angles.

∠4 = 55

And,

∠5 and ∠8 are vertical angles.

∠5 = 55

Now,

∠1 and ∠2 form a straight angle.

This means,

∠1 + ∠2 = 180

∠2 = 180 - 55

∠2 = 125

And,

∠5 and ∠6 forms a straight angle.

This means,

∠5 + ∠6 = 180

∠6 = 180 - 55

∠6 = 125

Now,

∠2 and ∠3 are vertical angles.

∠6 and ∠7 are vertical angles.

This means,

∠3 = 125

∠7 = 125

Part B:

∠1 and ∠7 are exterior angles on the same side.

This means,

∠1 + ∠7 = 180

Substituting the values.

55 + 125 = 180

180 = 180

This is true.

And,

∠1 and ∠2 form a straight angle.

This means,

∠1 + ∠2 = 180

55 + 125 = 180

This is true.

Thus,

The values of the angles are:

∠1 = 55

∠2 = 125

∠3 = 125

∠4 = 55

∠5 = 55

∠6 = 125

∠7 = 125

∠8 = 55

And,

∠1 and ∠7 are exterior angles on the same side.

∠1 and ∠2 form a straight angle.

Denzel buys a basketball for $24 plus 7.5% tax. Mel buys a football for $20 plus 8% tax. What is the difference in the amount Dave and Mel paid, including tax?

Answers

Answer:

Dave paid $4.20 more than Mel

Step-by-step explanation:

Lets start with Dave:

Turn the % into a decimal - so 7.5 % would be 0.075

Then multiply it to the amount in cost to get the tax - 24 x 0.075 = 1. 80

Now add the tax to the total - 24 + 1.8 = $25. 80  

Mel

Turn the % into a decimal - so 8 % would be 0.08

Then multiply it to the amount in cost to get the tax - 20 x 0.08 = 1. 60

Now add the tax to the total - 20 + 1.6 = $21.60  

To find the difference subtract Dave's with Mel's

$25. 80 - $21.60 = $4.20

The probabilities for the following statements are:

a) 1/4

b) 1/18

c) 1/3

d) 1/12

e) 1/6

f) 1/36

What is probability?

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.

We have,

The sample space for rolling a die twice.

= {1, 2, 3, 4, 5, 6 } x {1, 2, 3, 4, 5, 6}

= {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6) }

The number of possible outcomes.

= 36.

Now,

The number of outcomes where both are odd.

= { (1, 1), (1, 3), (1, 5), (3, 1), (3, 3), (3, 5), (5, 1), (5, 3), (5, 5) }

The probability that both are odd.

= 9/36

= 1/4

The number of outcomes where both are a perfect square.

= {1, 1), (4, 4) }

The probability that both are perfect squares.

= 2/36

= 1/18

The number of outcomes where the first is even and the second is less than 5.

= { (2, 1), (2, 2), (2, 3), (2, 4), (4, 1), (4, 2), (4, 3), (4, 4), (6, 1), (6, 2), (6, 3), (6, 4) }

The probability that where first is even and second, is less than 5.

= 12/36

= 1/3

The number of outcomes where the first is prime and the second is 6.

= { (2, 6), (3, 6), (5, 6) }

The probability where the first is prime and the second is 6.

= 3/36

= 1/12

The number of outcomes where both are the same.

= { (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6) }

The probability that both are the same.

= 6/36

= 1/6

The number of outcomes of at least 4 both times.

= {(4, 4)}

The probability that at least 4 both times.

= 1/36

if any body does Lincoln Douglas debate, please let me know because I could use some help with how wording on part of my case.

Answers

Answer:

Step-by-step explanation:

the Lincoln-Douglas debates propelled Lincoln's political career into the national spotlight, while simultaneously stifling Douglas' career, and foreshadowing the 1860 Election. By 1858, Stephen A. Douglas was the most prominent politician in the West. Lincoln-Douglas debates, series of seven debates between the Democratic senator Stephen A. Douglas and Republican challenger Abraham Lincoln during the 1858 Illinois senatorial campaign, largely concerning the issue of slavery extension into the territories. The result of the debates was inconclusive. Senators were then chosen by state legislatures, and in the 1858 legislative election, Illinois Republican candidates slightly outpolled their Democratic rivals. Southerners believed that Abraham Lincoln was an abolitionist and also felt betrayed by Stephen Douglas's suggestion that territories could refuse to grant slavery legal protection. In 1860, Lincoln won the Republican Party's presidential nomination.In that election, he faced Douglas (again), who represented the Northern faction of a heavily divided Democratic Party, as well as Southern Democrat John C. Breckinridge and Constitutional Union candidate John Bell.
