From what I can understand, they're telling you to say the types of numbers those groups fall into.
So, the first group, <span>A. {1, 2, 3, 4,…}, is natural numbers. The reason for that is natural numbers are any whole numbers that are positive and not zero.
The second group, </span><span>B. {0, 1, 2, 3,…}, would be whole numbers. The reason for that is whole numbers are non-negative numbers.
The third group, </span><span>C. {-2, -1, 0, 1, 2,…}, would be integers. The reason for that is integers are whole numbers that extend to the negative values.
</span>
I really hope this helps, have a great day :)

4.50+4.50=9.00=9
+
2.39+2.39=4.78
+
1.99
=

519 divided by 6 and 915 divided by 7 and 439 divided by 7 and 812 divided by 9 which one does not have a two digit quotient.

Setler [38]

519/6=86.5

915/7=130.7142

439/7=62.7142

812/9=90.2222

so i think its the 1st on but i may be wrong.

PLSS HELP geometry it's about relations within triangles. need help solving for variables

ValentinkaMS [17]

Using the definition of congruent triangles, the missing measurements are:

23. m = 7; LO = 14; NO = 14

24. x = 15; m∠QTS = 90°

25. p = 3; IJ = 15; KJ = 15

26. r = 3; UW = 48

27. y = 7; m∠DEF = 50°

28. m = 5; p = 10

<h3>What are Congruent Triangles?</h3>

If two triangles are congruent, then all its corresponding sides and angles are equal.

23. The two triangles are congruent by SAS, therefore:

LO = NO

m + 7 = 2m

7 = 2m - m

7 = m

m = 7

LO = NO = m + 7 = 7 + 7 = 14

LO = 14

NO = 14

24. But triangles are congruent by SSS, therefore:

3x = 5x - 30

3x - 5x = -30

-2x = -30

x = 15

m∠QTS = 2(3x) = 6x = 6(15)

m∠QTS = 90°

25. Both triangles are congruent by ASA, therefore:

4p + 3 = 3p + 6

4p - 3p = -3 + 6

p = 3

IJ = KJ = 4p + 3 = 4(3) + 3 = 15

IJ = 15

KJ = 15

26. The two triangles are congruent by SAS, therefore:

5r + 9 = 8r

9 = 8r - 5r

9 = 3r

9/3 = r

r = 3

UW = 2(8r) = 16r = 16(3)

UW = 48

27. Both triangles are congruent by SSS, therefore:

3y + 4 = 5y - 10

3y - 5y = -4 - 10

-2y = -14

y = 7

m∠DEF = 2(3y + 4) = 6y + 8 = 6(7) + 8

m∠DEF = 50°

28. Both triangles are congruent by SSS, therefore:

2m = 10

m = 10/2

m = 5

2p - 5 = p + 5

2p - p = 5 + 5

p = 10

The dashed line shows how you cut the bottom of a rectangular door so it opens more easily.

Anastaziya [24]

See the picture attached to better understand the problem

we know that
m ∠ACD=91.5°
m ∠ACD+m ∠ACB=180°-------> by supplementary angles
so
m ∠ACB=180-91.5-----> m ∠ACB=88.5°

m∠CAB+m ∠ACB=90°-----> by complementary angles
so
m ∠CAB=90-88.5-----> 1.5°
m∠ CAB is <span>the new angle at the bottom left side of the door

the answer is
1.5</span>°
