1\dfrac{1}{3}+2\dfrac{2}{3}=1+\dfrac{1}{3}+2+\dfrac{2}{3}=(1+2)+\left(\dfrac{1}{3}+\dfrac{2}{3}\right)=3+\dfrac{1+2}{3}\\\\=3+\dfrac{3}{3}=3+1=4

1-1/3 = 4/3

2-2/3 = 8/3

(4/3) + (8/3)  =  12/3

But 12/3 = 4 .

The only way to make a mixed number out of 4 is to call it "4 and 0/3".

identify the initial amount a and the rate of growth r (as a percent) of the exponential function H(t) = 175 (1.028)t. evaluate
Liula [17]

From the given exponential function, we have that:

  • The initial amount is of 175.
  • The growth rate is of 2.8%.
  • When t = 5, we have that H(5) = 201.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

In this problem, the function is:

H(t) = 175(1.028)^t

  • The initial value is of A(0) = 175.
  • The growth rate is of 0.028 = 2.8\%, as 1 + r = 1.028 \rightarrow r = 0.028.

When t = 5, we have that:

H(5) = 175(1.028)^5 = 201

To which subset of real numbers does -3 belong?
inessss [21]
<h3>Answer: C) integers and rational numbers</h3>

Explanation:

The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically any number that does not have a decimal or fractional part to it. We can say that this set is composed of positive and negative whole numbers along with 0. So this is why -3 is in the set of integers.

The value -3 is not in the set of whole numbers because the set of whole numbers is {0, 1, 2, 3, 4, 5, 6, ...}, so this rules out choice D.

Choice B is also eliminated because -3 is a rational number. We can write -3 as a fraction of two integers, example: -3 = -3/1. Any rational number is not irrational, and vice versa.

Choice A is ruled out because it's not the most complete answer (though its technically true).
