Answer:
Yes, Nadiya is correct. By multiplying the numerator and denominator by 2, the first fraction equivalent to 2/10 is 4/20.
Step-by-step explanation:
To find a fraction equivalent to 2/10, we need to multiply (or divide) the numerator and denominator by the same nonzero whole number.
As we need an equivalent fraction with a denominator greater than 10, we will need to multiply and not divide.
The first nonzero whole number we have is 1. If we multiply the numerator and denominator by 1, we get 2/10. Obviously, 2/10 is equivalent to 2/10 but the denominator is not greater than 10, so it doesn't help us.
The next whole number is 2. When we multiply the numerator and denominator by 2, we get 4/20. The denominator is not less than 20.
If we keep going, we will get 6/30, 8/40 and so on.
Therefore, Nadiya is correct.
The correct answer is the first one.
Answer:
14 gallons
Step-by-step explanation:
If 11 2/3 gallons represents 5/6 full bucket then we can equate that
x=1 full
Therefore, the bucket requires 14 gallons
The domain is the x values
y = 2 - x
when x = -3
y = 2 - (-3)
y = 2 + 3
y = 5....so ur points are (-3,5)
when x = -2
y = 2 - (-2)
y = 2 + 2
y = 4....so ur points are (-2,4)
when x = -1
y = 2 - (-1)
y = 2 + 1
y = 3...so ur points are (-1,3)
when x = 0
y = 2 - 0
y = 2....so ur points are (0,2)
when x = 1
y = 2 - 1
y = 1...so ur point are (1,1)
so basically, u plot all of those points
The answer is 10 cm
Imagine cement cover as a rectangle which volume is 660,000,000 cm3. So this rectangle has width (w = 60m), length (l = 110m), and height (h = ?). The height of the rectangle is actually a thickness of the cement layer. So, we will use the formula for the volume (V) of the rectangle to calculate the thickness:
V = w · l · h
It is given:
V = 660,000,000 cm³
w = 60 m = 60 · 100 cm = 6,000 cm
l = 110 m = 110 · 100 cm = 11,000 cm
h = ?
Using the formula: V = w · l · h
660,000,000 = 6,000 · 11,000 · h
660,000,000 = 66,000,000 · h
⇒ h = 660,000,000 ÷ 66,000,000 = 10 cm
