We know that 3/5 of the answer is right and 8 are wrong. If we do 5/5-3/5, we get 2/5 which is the amount of problems that are wrong or in other 8 wrong.
3/5=?
2/5= 8 wrong
If we make 2/5 into 1/5 we get 4 wrong answer.
Then we multiply 1/5 and 4 by 5 we get: 5/5 and 20 problems.
So there is 20 problems on the test.
Answer:
Step-by-step explanation:
Assuming this is a right triangle.
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse
Given:
- = 35°
- O = x
- A = 26
Therefore, x = 18.21 (nearest hundredth)
Answer:
x=16

300 (SS) = 600S
150 (Ss) = 150S and 150s
50 (ss) = 100s
750S and 250s
75% dominant S
25% recessive s
