Answer:
Wrong problems = 32
Step-by-step explanation:
Total no of problems = 200
Charlotte earned a grade of 84% on her multiple-choice.
Correct problems,
Wrong problems = 200 - correct problems
= 200 - 168
= 32
Hence, there are 32 problems on the final exam Charlotte get wrong.
Answer:
2
Step-by-step explanation:
You can fit two groups of 3/8. 3/4 is equivalent to 6/8. 3/8 goes into 6/8 two times therefore the answer is two groups of 3/8.
Answer:
b. 75.40
Step-by-step explanation:
The circumference of a circle is the perimeter of the circle. To find the perimeter we would use the formula ⇒ 2 × π × r ⇔ or π × d ← where r is the radius and d is the diameter .
So lets substitute in the values
2 × π × r
Radius = 12
2 × π × 12 = 24 π = 75.3982236862
So the answer is b. 75.40
6y-8x=14(1)
Y=x+5(2)
6y-8x=14(3) ×1
Y-x=5(4)×6
6y-8x=14
6y-6x=30
-2x=16
X=8
Put x into equation 1
6y-8x=14
6y-8(8)=14
6y-64=14
6y=14+64
6y=78
6y=78
Y=13
Answer:
The other angles measure to 90 and 55.
Step-by-step explanation:
This is the answer, because since it is a right triangle, we know that one of the other angles is equal to 90 degrees. But the other one is still not known. Now it is, because all of the angles together should all add up to 180 degrees. So all you need to do is subtract 90 and 35 from 180, and you should end up with 55. And because it is a right triangle, then two of the angles will be acute, and the other one will always be 90 degrees. If you had just one of the acute angles and the measurement of the right angle, then just subtract the two angle measurements from 180 and you get the other measurement of the other acute angle. I hope this helps you in some way, and have a great day.
