(6 + 1/4)·4 = (6·4) + (1/4·4) = 24 + 1 = 25
Or, you can convert the mixed number to the improper fraction 25/4 and then multiply by 4 to get 25.
Answer:
42 and 138
Step-by-step explanation:
Supplementary angle mean that the sum of both angle will be 180 degrees. If the angle is X and Y the equation will be:
x + y = 180
x= 180-y
If three times the measure of one angle(X) is 12 degrees less than the measure of the other(Y), the equation will be
3x= y-12
If you insert first equation to second equation, you can find out:
3x= y-12
3(180-y)= y-12
540-3y= y-12
540+12= y+3y
552= 4y
y= 138
x=180- y
x= 180-138
x= 42
Answer:
In other words, the area of a square is the product of the length of each side with itself. That is, Area A = s x s where s is the length of each side of the square. For example, the area of a square of each side of length 8 feet is 8 times 8 or 64 square feet.
Step-by-step explanation:
Answer:
1). Rational
2). Irrational
3). Rational
4). Rational
5). Irrational
Step-by-step explanation:
To solve this question we should follow the rule,
"Addition of rational and an irrational number is an irrational number."
1). (rational number)
(negative rational number)
[rational number]
2). π → (Irrational number)
24 → (rational number)
π + 24 → (Irrational number)
Since addition of a rational and an irrational number is an irrational number.
3). = 2 (rational number)
5 (rational number)
2 + 5 = 7 (rational number)
4). (rational number)
(rational number)
(rational number)
5). (rational number)
→ (Irrational number)
→ (Irrational number)
