A rational number is an algebraic term expressed as a fraction. The fraction can also be in decimals but only if the decimal places are not repeating or not infinitely long. If they aren't, then these are called irrational numbers.
Let's try each of the choices:
A. The term 2/4 is a rational number. Now, when 0.3 or 3/10 is added to it, the sum would be 4/5 or 0.8. This is a rational number.
B. √7 is an irrational number because its exact value is 2.645751311.... Even if you add 0.3 to it, the answer would still be irrational
C. Obviously, this is an irrational number
D. The exact value of π is <span>3.14159...... If 0.3 is added to it, the answer would be 3.441592654. This is irrational.
Therefore, the answer is A.</span>
Answer:
(12.2,-6.4)
Step-by-step explanation:
The results from Desmos are as shown.
The displayed values are (12.294, -6.353)
Answer:
Step-by-step explanation:
- (y+9) = 10
Multiply through by -1 gives us
y+9 = -10
Subtract 9 from both sides
y = -19
That's your answer.
If you work it through it satisfies the equation.
That is:
- (-19 +9) = 10
-(-10) = 10
10 = 10
Boo ya!
Answer:
19,200 yds²
Step-by-step explanation:
The question is asking for how many <em>square yards</em> of grass is needed
This means that it is looking for the Area.
The formula for area is <em>Length x Width = Area</em>
<em>120</em> (Length)
<em>160</em> (Width)
<em>120 x 160</em> = 19,200
The unit of measurement is yards...
19,200 yds²
