Step-by-step explanation:
Given
[ 6 + ( 10- 8 ) *7 ] + 5
= [ 6 + 2 * 7] + 5
= [ 6 + 14 ] + 5
= 20 + 5
= 25
2,640,000. Because the 4 is in the ten thousands place and should be rounded up
N + (n+1) + (n+2) + (n+3) = 90
if n is the first number, then the next number is 1 more than n, the next number is 2 more than n, etc.
Simplify the above expression:
4n + 6 = 90
4n = 84
n = 21
n+1= 22
n+2 = 23
n+3 = 24
The expression that is equivalent to 9^5 is 3^2
Answer:
Riya does not pass
Step-by-step explanation:
From the question:
Section A has 80 marks
Section B has 120 marks.
The total marks from both sections = 200 marks
To pass, Riya needs to score 65% of the total marks.
Hence: 65% of 200 marks
= 65/100 × 200
= 130 marks.
To pass Riya must score 130 marks.
Riya scores:
For section A
55% in Section A
Her marks in section A = 55% × 80
= 55/100 × 80
= 44 marks
For section B
70% in Section B.
Her marks in section A = 70% × 120
= 70/100 × 120
= 84 marks
Therefore , the total marks Riya scored in both sections =
44 marks + 84 marks
= 128 marks
Riya scored a total of 128 marks. SHE DOES NOT PASS. Because the pass mark is a total of 130 marks from Section A and Section B
