First find 60% of 145 =
60% of 45 equals 87.
Now subtract 87 from 145.
145 - 87 = 58
So there were 58 girls.
Answer:
2x³ - 3y + z²
Step-by-step explanation:
-2x³ – y – 2z² + 4x³ – 2y + 3z² Combine like terms
-2x³ + 4x³ – y – 2y – 2z² + 3z²
2x³ - 3y + z²
Triangle a - acute
Triangle b - acute
Triangle c - acute
Triangle d - right
Answer:
y = 4/7x + 13/7
Step-by-step explanation:
m = 3+1/2+5 = 4/7
i used the coords (-5, -1)
y + 1 = 4/7 (x+5)
y + 1 = 4/7x + 20/7
y = 4/7x + 20/7 - 1
y = 4/7x + 13/7
Answer: Consider a power set of real numbers.
The subsets of the power set are as follows:-
1. Natural number()={1,2,3,4,5,....}
2.Whole numbers={0,1,2,3,4,......}
3.Integers()={.......-3,-2,-1,0,1,2,3,....}
4.Rational numbers()=It contains all of the above subsets and fractions (where denominator ≠ 0) ,terminating and repeating decimals.
5.Irrational numbers=It contains numbers which cannot be expressed as the ratio of integers, and they are non-repeating, non-terminating decimals.
