An exam has two papers, Paper 1 and Paper 2 Paper 1 has 60 marks.
Paper 2 has 90 marks.
The pass mark is 2/3 of the total number of marks.
Danielle gets 70% of the marks for Paper 1
How many of the marks for Paper 2 must Danielle get in order to get the pass
mark?

58 out of 90 = 64%

Step-by-step explanation:

Total number of marks for both tests = 60 + 90 = 150

She has 70% on test 1.

70% of 60 is 70/100 * 60 =                                  42 marks from test 1

To pass she needs 2/3 * 150 = 300 / 3 = 100

That means she needs 100 - 42 = 58 marks on test 2

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
