Your answer is 3/4. hope this helps.
I believe the answer is
1.1-(-3.8)=4.9
Answer:
512 is a perfect cube because 512 = 8 times 8 times 8
Step-by-step explanation:
A perfect cube is a number that can be rewritten as a product of three identical numbers.
For example: 8 is perfect cube as 8 can be rewritten as:
8 = 2 × 2 × 2
So, from the definition of the perfect cubes, the option that matches it is third option.
512 is a perfect cube as it can be expressed as the product of 8 three times.
512 = 8 × 8 × 8
Therefore, third option is correct.
All the remaining options doesn't fulfill the definition of perfect cubes.
Answer:
0.25
Step-by-step explanation:
Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x
