Answer:
D
Step-by-step explanation:
D. All of the terms in set D are rational, as they can be expressed as decimal/fractions. sqrt25 is rational, because it simplifies to 5, which is rational.
Answer:
BE ≈ 92 m
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part of the secant and the entire secant, that is
BE² = 59(59 + 83) = 59 × 142 = 8378 ( take the square root of both sides )
BE = 
≈ 92 m ( to the nearest metre )
Problem 1) xy means "x times y". The multiplication symbol is left out because its implied. You can write x*y if you wish. Or we can say "product of two numbers" since a product in math terms is the result of multiplication.
---------------------------------------------
Problem 2) x/y means "x divided by y" which is a fraction
---------------------------------------------
Problem 3)
Writing "x-y" is the same as saying "x minus y"
---------------------------------------------
Problem 4)
x+y is "x plus y", or we can say "the sum of x and y". The "sum" is "result of adding two or more values"
---------------------------------------------
Problem 5)
y-x is "y minus x" or we can say "x subtracted from y"
---------------------------------------------
Problem 6)
y division symbol x is essentially the flip of problem 2. We'd say "y divided by x"
---------------------------------------------
Problem 7)
x+y = 6 is "the sum of two numbers is 6". See problem 4 above.
---------------------------------------------
Problem 8)
xy = 6 is "the product of two numbers is 6". This is an extension of problem 1.
---------------------------------------------
Problem 9)
6x = y is "six times a number equals y" when translated out
---------------------------------------------
Problem 10)
y = x-6 would translate to "six less than a number is y"
where the "a number" portion is represented by x
A multiple is a number that can be gotten from multiplying a number by any number. For example, a multiple of 3 would have to be something that you can count by threes to get to. The same applies to 10, if you count by tens, any of those numbers that you get while counting by tens would be a multiple of 10.
