Answer:
3 and 7
Step-by-step explanation:
You know from your multiplication tables that ...
21 = 1×21 = 3×7
There are no other factorizations of 21 using integers. You may notice that the sums of these factors are ...
1+21 = 22
3+7 = 10 . . . . . . this is the pair of numbers you are looking for
The two numbers are 3 and 7.
Answer:
table c
Step-by-step explanation:
Answer:
1) y = 115°
2) x = 120°
3) x = 163°
Step-by-step explanation:
- the sum of the interior angles of a figure = (number of sides - 2) * 180
1)
the sum of the interior angles of this figure = (5 - 2) * 180 = 540°
the fifth angle = the sum of the interior angles - the sum of the four angles
the fifth angle or y = 540 - (90 + 135 + 112 + 88) = 115
2)
the sum of the interior angles = (6 - 2) * 180 = 720°
x = 720 - (90 + 90 + 140 + 150 + 130) = 120
3)
the sum of the interior angles = (5 - 2) * 180 = 540°
x = 540 - (68 + 121 + 103 + 85) = 163
Answer:
I think it's £200 because 100% of 100 is 100 so 200% of 100 is 200.
The correct answers are 1. C, 2. C, 3. D, 4. D, 5. D
