1 2/3 = 5/3
2 1/3 = 7/3
2 = 2
5/3 * 7/3 * 2 = 70/9 cubic inches = 0.127455 liters
Answer:
720 miles
Step-by-step explanation:
180mi/2.5hr=72 mph
72mph (10hr)=720 miles
Answer:
<em>17.1 feet</em>
Step-by-step explanation:
Scale drawing = 5.7 inches
scale = 1 inches = 3 feet
If 1 inches = 3 feet
5.7 inches = 
feet
solving for , we cross-multiply
x 1 = 5.7 x 3
= <em>17.1 feet</em>
The formula for a rectangle is length*width=area. Since we know the area and the width, we plug it in to the formula, we get length*9=648.
l*9=648 is equivalent to l=648/9. Now we solve <span>l=648/9 and get l=72. SO the width is 72 inches. </span>
Answer:
See below.
Step-by-step explanation:
Since sqrt(a) and sqrt(b) are in simplest radical form, that means a and b have no perfect square factors. When sqrt(a) and sqrt(b) are multiplied giving c * sqrt(d), the fact that c came out of the root means that there was c^2 inside the product sqrt(ab). This means that a and b have at least one common factor.
ab = c^2d
Example:
Let a = 6 and let b = 10.
sqrt(6) and sqrt(10) are in simplest radical form.
Now we multiply the radicals.
sqrt(a) * sqrt(b) = sqrt(6) * sqrt(10) = sqrt(60) = sqrt(4 * 15) = 2sqrt(15)
We have c = 2 and d = 15.
ab = c^2d
6 * 10 = 2^2 * 15
60 = 60
Our relationship between a, b and c, d works.
