So, you start out with 100 students. 85% are good students, so 85 good students. If 10 more good students were to join the school, then your total of 100 would increase by 10. 100+10=110. Your number of good students would also increase by 10. 85+10=95. To find the new percent, do division. 95/110 rounds to 86%.
First you subtract 60-5 to see how much time you will have left to play.
60-5= 55
Then you divide 55/7 to see how many levels you can play for free.
55/7= I got 7.85 (rounded).
I hope its correct and sorry if its wrong! :)
Answer:
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.

Answer:
Step-by-step explanation:
a)
428721
Place of 2's 10s and 10,000s
Therefore its value is 20 and 20,000
Product of the place value = 20 x 20,000 = 4,00,000
b)
37,20,861
Place of 7 is 1,00,000
Therefore the place value is 7,00,000
c)
Greatest 7 digit number is 99,99,999
Adding 1 to it = 99,99,999 + 1 = 1,00,00,000
d)
85642 = 80000 + 5000 + 600 + 40 +2
e)
round off 85642 to nearest thousand = 86,000
Firstly, we will draw diagram of the scenario
Dana reflects point A(2,5) across line small script letter lℓ to get image point Upper A primeA′(6,1)
It means that AA' is perpendicular bisects of line(l)
so, let's assume it intersects at point M
so, M will be mid-point between A and A'


M is a point on line (l)
now, we will find slope of line on AA'
x1=2 , y1=5
x2=6 , y2=1

now, we can plug values


now, we know that line (l) and AA' are perpendicular to each other
so, slope of line(l) is -1/m
slope=1
so, we have slope and a point


now, we can use point slope form of line

now, we can plug values


so, the equation of line (l) is
