Therefore, the required vertices after rotation are W'(5,3), X'(3,1),Y'(5,-1) and Z'(7,1).
The formula for the circumference of a circle = 2 x radius x pi
The radius is given as 21 cm and pi = 3.142
Circumference = 2 x 21 x 3.142 = 131.964 cm
Complete question :
John and Kamira are playing a game. John's score (J) and Kamira's score (K) after round 1 are shown on the number line.
The score recorded at the end of the first round is 2.
What could this score represent?
Options :
the sum of John's score and Kamira's score
the difference between John's score and Kamira's score
the absolute value of the difference of John's score and Kamira's score
the sum of the absolute value of John's score and the absolute value of Kamira's score
Answer:
the sum of John's score and Kamira's score
Step-by-step explanation:
Given that :
The score recorded at the end of the round is 2
From the attached number line :
John's score = - 5
Kamira's score = 7
Sum = - 5 + 7 = 2
Difference = - 5 - 7 = - 12
Sum of absolute value = 5 + 7 = 12
absolute value of difference = 12
Answer:
The desired expression is 19 x (3 tens) = 19 x 30 = 570
So, the greatest ten = 3 (tens)
Step-by-step explanation:
Let us check each tens.
19 x (1 ten) = 19 x 10 = 190
19 x (2 tens) = 19 x 20 = 380
19 x (3 tens) = 19 x 30 = 570
19 x (4 tens) = 19 x 40 = 760
But, here 760 is OVER the given term 684.
and 570 is the nearest value to the value 684.
So, the desired expression is 19 x (3 tens) = 19 x 30 = 570
