Answer:
10+(n/2)=6
Step-by-step explanation:
Let the number be n
Quotient of n and 2 is (n/2)
Sum of this and 10 is
10+(n/2)=6
8 inches, because you devide 32/4, which gives you 8.
Answer:
42%
Step-by-step explanation:
Water wasted last year = 75,900 gallons
Water wasted this year = 44,022 gallons
Percentage decrease in the amount of water wasted yearly = (Water wasted last year - Water wasted this year) / Water wasted last year × 100
= (75,900 - 44,022) / 75,900 × 100
= 31,878 / 75,900 × 100
= 0.42 × 100
= 42%
Percentage decrease in the amount of water wasted yearly is 42%
Answer:
The distance from B to B' is 5 units
Step-by-step explanation:
we know that
A translation is a rigid transformation, that means, the size and the shape of the pre-image is the same that the size and the shape of the image after the translation
so
The distance AA' will be equal to the distance BB'
the formula to calculate the distance between two points is equal to
we have
A(1,5) and A'(-2,1)
substitute
therefore
The distance from B to B' is 5 units
Answer:
True mathematical statement.
"If x = 0, then for any real number y, we have: y*x = 0."
This is true, and we can prove it with the axioms of the real set.
A false mathematical statement can be:
"if n and x are integer numbers, then n/x is also an integer number."
And a counterexample of this is if we took n = 1 and x = 2, both are integer numbers, so the first part is true, but:
n/x = 1/2 = 0.5 is not an integer number, then the statement is false,
