Answer:
See below.
Step-by-step explanation:
Increases by 25% :- it is 80 * 1.25 = 100.
100 decreased by 25% = 100 * 0.75
= 75.
Answer:
The smallest diameter of wrapper that will fit the candy bar is 6 cm
Step-by-step explanation:
The smallest diameter of the wrapper will have to be the length of the line AC.
We can observe that there are two similar triangles present in the shape there.
We have triangle ADE and triangle DCF
They are similar because their left side, base length, and right angle are equal.
We are given the length of the side AD for triangle ADE.
From the rules of similar triangles, we have that side DC will also equal 3 cm. because the two triangles are similar.
Hence AC will be 3cm + 3cm = 6 cm
The smallest diameter of wrapper that will fit the candy bar is 6 cm
Answer:
x < - 17 or x > 7
Step-by-step explanation:
Inequalities of the form | x | > a always have solutions of the form
x < - a or x > a
For | x + 5 | > 12, then
x + 5 < - 12 or x + 5 > 12 ( subtract 5 from both sides of the inequalities )
x < - 17 or x > 7

Step-by-step explanation:
<u>Area of a Circle</u>
A circle is a geometric shape where all the points on its circumference are at the same distance to a fixed point called center. The radius is the distance from the center to any point of the circumference.
The relation of the length of the circumference to the radius is an irrational number called pi (
).
Another interesting relation in a circle is the area it occupies in a 2D space. Being r the radius of the circle, the area is computed by the formula
The party hat has a radius of r= 3 inches. The area of the circular base is computed as follows
