the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements

The radius of a circle is 2 millimeters. What is the circle's area?
mote1985 [20]

Answer:

12.56 mm²

Step-by-step explanation:

A=\pi r^{2}

Plug the given values into the area equation

A=3.14*2^{2}\\A=3.14*4\\A=12.56

Therefore, the area of the circle is 12.56 mm².

I hope this helps!

Answer:

yes in fact Josiah will have Extra left over

Step-by-step explanation:

So you see,

1 3/4 feet x 5 = 8 3/4 which is 1.375 less than 10 1/8 feet

Therefore, Josiah will have more than enough to build 5 shelfs.

Suppose we roll a fair six-sided die and sum the values obtained on each roll, stopping once our sum exceeds 285. Approximate th
OlgaM077 [116]

Answer:

1

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Assuming we stop rolling the six-sided die once our sum is 290 ( exceeds 285)

Number of possible outcomes = 75, number of total outcomes = 290

Probability (75 rolls are needed to get this sum) = 75/290 = 0.259

Probability (more than 75 rolls are needed to get this sum) = 1 - 0.259 = 0.741

Probability (at least 75 rolls are needed to get this sum) means that either 75 rolls or more than 75 rolls are needed to get this sum = 0.259 + 0.741 = 1

A Conjuncture and the paragraph proof used to prove the conjecture are shown
Finger [1]

Answer:

Given

This is our initial premise.

2) Linear pairs of angles are supplementary

This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.

3)

The definition of supplementary angles is that two angles are supplementary if their measures sum to

.

4) Substitution of 1. into 3.

As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.

5)
