Answer:
874×1 = 874
874×10 = 8,740
874×100 = 87,400
874×1,000 = 874,000
Step-by-step explanation:
Answer: B has greater spread than A.
Step-by-step explanation:
Since we have given that
Set A: {38, 12, 23, 48, 55, 16, 18}
Range of A = Highest - Lowest
Range of A = 55 - 12
Range of A = 43
Set B:{44, 13, 24, 12, 56}
Range of B = Highest - Lowest
Range of B = 56 - 12
Range of B = 44
Since Range of B is more than range of A.
Hence, B has greater spread than A.
Answer:
x = 22
Step-by-step explanation:
The figure is attached below.
Its given that SV is parallel to RU. We have to find the value of x.
Observe that, if we join point V to U, we will obtain a parallelogram RSVU. One of the properties of a parallelogram is that the sum of its two adjacent angles is always 180 degrees.
So, the two adjacent angles would be: ∠S and ∠R
From the figure:
∠S = 5x + 4
∠R = 44 + x
Since,
∠S + ∠R must be 180 degrees, we can write:
∠S + ∠R = 180
5x + 4 + 44 + x = 180
6x + 48 = 180
6x = 132
x = 22
Therefore, the value of x is 22.
