Answer:
3 3/8 or 3.375
Step-by-step explanation:
The total weight is:
4 3/8 + 2.5 + 3 1/4 =
= 4.375 + 2.5 + 3.25
= 10.125
= 10 1/8
Now we divide the total weight by 3.
(10 1/8)/3 =
= 81/8 ÷ 3
= 81/8 × 1/3
= 27/8
= 3 3/8
Answer: 3 3/8 or 3.375
Answer:
The greatest common factor of 42, 60 and 78 is 6.
Step-by-step explanation:
The given numbers are : 42, 60 and 78
On Prime Factorization of the given terms, we get:
42 = 2 x 3 x 7
60 = 2 x 2 x 3 x 5
78 = 2 x 3 x 13
The common factors to all these three terms is 2 x 3 = 6
Hence, the greatest common factor of 42, 60 and 78 is 6.
Answer
1. x = (2/3)y²
2. x = 54 when y = 9
3. y = 7.35 when x = 36
Explanation
1. x ∝ y²
x = 24, y = 6
x = ky²
24 = k x 6²
24 = 36k
k = 24/36
k = 2/3
∴ x in terms of y is x = (2/3)y²
2. Using x = (2/3)y² to to find x when y = 9, we have
x = (2/3) x 9²
x = 2/3 x 81
x = 2 x 27
x = 54
∴ x = 54 when y = 9
3. Using x = (2/3)y² to to find y when x = 36, we have
36 = (2/3)y²
36 = 2y²/3
2y² = 36 x 3
y² = 108/2
y² = 54
y = √54
y = 7.35
∴ y = 7.35 when x = 36
Answer:
x= 10 hope it helps have a nice day
