Answer:
hundredths I think
Step-by-step explanation:
I did this a few years ago so forgive me if I'm wrong
V = 25,364.4 cm^3 Is volume
r = 2.7g/cm^3 Is density
To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.
m = 68,486,6 g is the answer.
Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = 
= 
= 0.5, hence
y = 0.5x ← equation of variation
Inequalities are used to relate unequal expressions
The greatest whole number of square yards the teacher can buy is 4
The inequality is given as:
When the <em>number of square yards </em>of the white fabrics is 10.
It means that: x = 10
So, we have:
Collect like terms
Divide both sides by 10
The above inequality means that:
The greatest whole number of square yards the teacher can buy is 4

Answer:
x(x - 6)(x + 8)
Step-by-step explanation:
First, the GCF of these 3 terms is x.
So to separate x from this it now becomes x(x^2 + 2x - 48).
Now to factor the expression inside the parentheses easily I use "a" and "b" to make it easier.
a + b = 2 (from 2x)
a * b = -48 (from third term of expression)
a = -6, b = 8
Substitute "a" and "b" and I get: x(x - 6)(x + 8)
