Answer:
<em>15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.</em>
Step-by-step explanation:
<u>Length, Area, and Volume Scale Factors</u>
If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is and the scale factor of their volumes is
.
We are given the scale factor of the surface areas of two similar containers A and B as 4:25.
The length scale factor is
The volume scale factor is: = 125:8 = 15.625
Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.
Thus, after she pours the 15th container, in the middle of the next one, the work will be done

Answer:
x = 4
Step-by-step explanation:
If you do not want to read the explanation go the the next part in bold
Ok so the shorter leg of the triangle is a radius of the circle. ( This is indicated by the point in the middle of the circle.) for the hypotenuse we are given one part of the length (2) The other part also happens to be a radius ( remember that a radius is a line that starts from the center of the triangle to any point of the circumference. ) Also remember that the radius is equal to 3. That being said the hypotenuse = 2+3 which equals 5.
This triangle then happens to be a right triangle. ( A triangle formed by a tangent line and a radius is a right triangle.) This means that we can use the Pythagorean theorem to solve for x.
Below here is where the work is shown
a² + b² = c². where a and b = legs and c = hypotenuse. We are given the hypotenuse (5) and a leg (3) So we plug in what we are given and solve for the missing information. 5² = 3² + b²
5² = 25
3² = 9
we would then have 25 = 9 + b²
Next we subtract 9 from each side
25 - 9 = 16
9 - 9 cancels out
Now we have 16 = b²
finally we want to get rid of the ²
To do so we take the square root of each side
we're left with b = 4 which means that x = 4
