Answer:
660 mm
Step-by-step explanation:
we know that
The scale factor is
That means
1 unit in the model represent 15 units in the actual
or
1 m in the model represent 15 m in the actual
To find out the height of the model rocket, divide the height of the actual rocket by 15
so
Convert m to mm
Remember that
To convert meters to millimeters, multiply by 1,000
so
Answer:
x ≤ 4
Step-by-step explanation:
Given
x +
≤ 4 , that is
x + 2 ≤ 4 ( subtract 2 from both sides )
x ≤ 2 ( multiply both sides by 2 to clear the fraction
x ≤ 4
Answer:
32 bottles
Step-by-step explanation:
In this scenario, we have to divide 8 by 1/4 to see how many of those 1/4-liter bottles can be filled with 8 liters of water. So, let's go ahead and see how this looks mathematically, then we'll start simplifying:
÷
Dividing by a fraction is the same as <em>multiplying by that same fraction's reciprocal</em>, so we can rearrange our math to make things easier.
×
Now, we can multiply the numerators and the denominators.
×
So 32 of those 1/4 liter bottles can be filled from a jug containing 8 liters of water. Hopefully this was helpful! If anything was confusing or didn't make sense, let me know so I can make things clearer. :)
