Answer:
The formula is a^2 + b^2 = c^2
Step-by-step explanation:
A and B are legs and C is the hypothunisis.
The theorem is used for triangles.
4^2 + 5^2 = c^2
16 + 25 = c^2
41 = c^2
sqr(41) = sqr(c)^2
c = 6.403124237
Height (h) = 24 mm
Diameter = 6 mm
Radius (r) =
= 3 mm
Area =
= 216 * 3.14 = 678.24 mm²
Answer:
The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.
Answer:
1 coin
Step-by-step explanation:
Given that c is number of coins, p the points collected and 20 is the constant.
-The equation for total points is p=20c, therefore, we calculate the number of coins as:
#Hence, Rita only has to collect 1 coin to earn 20 points.
