Answer:
4.5/2 which is 2.25
Step-by-step explanation:
2x-2 must be zero or greater, since we cannot have a negative quantity under the radical sign (unless we allow for imaginary roots).
Solving 2x-2≥0, we get x-1≥0, or x≥1. x must be equal to or greater than 1.
16 - 16, so the answer to the 2nd problem is the fourth one: x=4.
Answer:
$2.15
Step-by-step explanation:
Since 3 Tomatoes cost $1.29
Then let's first find how much is 1 Tomatoes.
To do that we have to divide Cost by # of Tomatoes
3/1.29 = 0.43
Thus, 1 Tomatoes Cost 0.43
Now, the question is: How much will 5 tomatoes cost?
Therefore, 0.43 * 5 =2.15
Hence, 5 Tomatoes cost $2.15

Answer:
we know that, Volume of cube=a³
Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)
Step-by-step explanation:
ATQ: 2x=a³ and, x=A³
a=³√2x and, A=x
we know that, surface area of cube is 6a²
Thus, surface area of 1st cube = 6(³√2x)²
= 6³√4x²
Surface area of 2nd cube=6(x)²=6x²
Ratio of S.A=(6³√4x²)÷(6x²)
Ratio of S.A=³√4:1
