Rational number is part of a whole number therefore both of them are rational
AVprozaik [17]4 years ago

Answer:

rational

Step-by-step explanation:

A rational number can be expressed in the form

\frac{a}{b} ← where a and b are integers

Given

0.75 × 0.82

= \frac{75}{100} × \frac{82}{100}

= \frac{3}{4} × \frac{41}{50}

= \frac{3(41)}{4(50)}

= \frac{123}{200} ← rational number

Which expression is equivalent to x2+3x+ 3+ (2x+134+15) - (x+5))
tia_tia [17]

Answer:

x^{2} + ( 4x) + (147)

Step-by-step explanation:

Here, the given expression is

x^{2} +3x +3 + (2x+134+15) - (x+5)

Now, simplifying the brackets, we get

x^{2} +3x +3 + (2x+134+15) - (x+5) = x^{2} +3x +3 + 2x+134+15 - x -5

Now, operate on the like terms.

= x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)

=x^{2} + ( 4x) + (147)

Hence, the given expression is simplified to the quadratic equation x^{2} + ( 4x) + (147)

On a recent trip, Juan started at an elevation of 1200 feet above sea level. He descended into a valley 20.4 feet below sea leve
liraira [26]

A would be the correct answer because he is up in elevation so that makes the 1200 positive and he goes down 20.4 which is negative and is goes that far down!!

hope this helps

I need help <br><br> Evaluate functions from their graph
andreev551 [17]

Answer:

g(7)=4

Step-by-step explanation:

We look for where x=7. The way you find the answer is first, find the point (0, 7). Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).

Using this method here, we see that g(7) intersects our line at (7, 4), so g(7)=4.
