How will you know if angles are congruent or supplementary?

Mathematics
1 answer:
Nataly_w [17]3 years ago

Answer:

congruent angles are angles that have the same degree so for example a 45° angle and another 45° angle are congruent

supplementary angles are two angles that add up to 180° or in other words a straight line so an angle that is 100° along with an angle that is 80° would be supplementary

Answer:

The density of the pine log is 0.2842 pounds per inch.

Step-by-step explanation:

To calculate the density of an object, you must divide its mass by its volume (radius times height). Thus, given that the pine log that has a 5-inch radius and is 30 inches long, while its weight is approximately 42.63 pounds, the following calculation must be performed to determine its density:

X = 42.63 / (30 x 5)

X = 42.63 / 150

X = 0.2842

Thus, the density of the pine log is 0.2842 pounds per inch.

I don't understand the question

Answer: 7 pigeons sitting on the branches,  5 pigeons under the tree

=12 in total

Step-by-step explanation:

Upper branch has x pigeons, lower has y.

Top branch said: "If one of you flies up to us our number will be double yours":

Well, if one of the bottom branch flies up, the top branch will have x+1 birds and the bottom will have (y−1). The top will have double the bottom, so:

x+1=2(y−1)

Top branch said: "If one of us flies down to you, our numbers will be equal":

Now, the top branch will have x−1 and the bottom y+1. The numbers should be equal:

x−1=y+1

7. What is the next fraction in each of the following patterns?
serious [3.7K]

Answer:

36/40, 47/101, 192

Step-by-step explanation:

(a)The numerator (top number of the fraction) is adding up by odd numbers in order.

From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.

The next number to add would logically be 11. So from 25/40 you would go to 36/40.

36/40 is your next fraction.

(b)

3+4=7,4+7=11,7+11=18,11+18=29,18+29=47

(c) 1*2=2,2*2=4,2*4=8,4*8=32,8*32=256,32*256=8,192
