What are rational numbers

Mathematics
1 answer:
Sophie [7]3 years ago

A rational number is a number that can be written as a fraction or "ratio".
It includes the set of integers because all of them have a denominator of 1.  A rational number can take on the form of \frac{a}{b} where b ≠ 0.  Terminating and repeating decimals are rational numbers because they too can be written as a ratio; for example, 0.3 = \frac{3}{10} or 0.3333... = \frac{1}{3}.

Your teacher recently found an old Nintendo in a thrift store. Use the formula to predict the value of the Nintendo in 2020. (Re
9966 [12]

The value of the Nintendo after 35 years is $2455

Since the formula f(x) = 3x² - 40x + 180 predicts the value of the Nintendo x years after 1986.

Since we require the value in 2021, x years after 1986 is 2021 - 1986 = 35 years.

Substituting x = 35 into the equation, we have

f(x) = 3x² - 40x + 180

f(x) = 3(35)² - 40(35) + 180

f(x) = 3(1225) - 40(35) + 180

f(x) = 3675 - 1400 + 180

f(x) = 2275 + 180

f(x) = 2455

So, the value of the Nintendo after 35 years is $2455

Do you think this is a realistic prediction of the value of that Nintendo?

This is not a realistic prediction for the value of the Nintendo, because, it is too high.

stepladder [879]

Answer:

area= 59.5    perimeter=31.6

Step-by-step explanation:

the area of the square is 49 because 7x7=49 and the area of the triangle is 3x7/2 because it is half of a rectangle so it is 10.5 + 49 = 59.5 and perimeter you add all the sides so 3+7.6+7+7+7= 31.6
