Answer:
72 Wrong, so find how many are right with 135 total
Step-by-step explanation:
It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.
so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number. If it helps 8/15 is about 53%. just like 1/2 is half. So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.
so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72. So 72 wrong so al others are right, which you get with 135-72 = 63.
You could also do 135*(1-8/15) = 135 * 7/15. if you ever want to find something NOT part of the proportion you do 1 - that proportion.

Answer:
x = 1
Step-by-step explanation:
We know that the two angles must be equal to each other. So:
65x - 12 = 43x + 10
First add 12 to both sides:
65x - 12 + 12 = 43x + 10 + 12
65x = 43x + 22
Then subtract 43x from both sides:
65x - 43x = 43x - 43x + 22
22x = 22
x = 1
Answer:
[-1,1]
Step-by-step explanation:
The question in English is
which of the following intervals contains the number 0?
case A) (0,1]
All real numbers greater than zero (the number 0 is not included) and less than or equal to 1 (the number 1 is included)
case B) [-1,1]
All real numbers greater than or equal to -1 (the number -1 is included) and less than or equal to 1 (the number 1 is included)
In this interval is included the number 0
case C) [-1,0)
All real numbers greater than or equal to -1 (the number -1 is included) and less than 0 (the number 0 is not included)
Answer:
3π
Step-by-step explanation:
The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.
The radius is given ad 6. So the circumference is:
2*π*6=12π
Now, since the angle of the arc is 90°, this is 1/4 of the circle.
This means that the arc length of this section will be 1/4th of the total circumference which is:
12π/4=3π
