the sequence is in multiples of 4 (2*4=8, 8*4=32, 32*4=128)
so 128*4=512, 512*4=2048, 2048*4=8192 & 8192*4=32768
2+8+32+128+512+2048+8192+32768=43690
The answer is: positive 61.
Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
Width of key in student calculator = 14 millimeter (1.4 cm)
Width of key in demonstration calculator = 2.8 cm
Thus, the demonstration calculator's dimensions are twice that of students' (in cm)
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
Step-by-step explanation:
-3 times -6r= 18r
-3 times 6 =-18
18r=-18
R=-1
If the answer is wrong try just 1
Percentage that needs to be determined = 24%
The quantity from which the percentage has to be determined = 1321
Then
24% of 1321 = (24/100) * 1321
= 31704/100
= 317.04
So from the above deduction we can easily say that 24% of the number 1321 is 317.04. I hope the procedure is not very complicated for you to understand. You can use this method for solving similar type of problems in future without requiring any help from anyone. Only be careful while calculating. Other than the calculation part, there is nothing tough about the problem.
