Estimation helps when there’s a lot of decimals or you want to get the basic number. For an example if you wanted to count the basic population of an area you wouldn’t say 15,347 people you would say over 15,000 people. Hope this helps!
Answer:
25
Step-by-step explanation:
if you look at it, 250 is 1/4 of 1000 and 100 is 1/10 of 1000 so divide 250 by 10 and you get your answer.
∠C is 148°.
Step-by-step explanation:
- Step 1: Given ∠A = 16° and ∠B = (10x - 64)°. Also, AC = BC. Now, the angles opposite to equal sides of a triangle are equal. So ∠B = 16°
- Step 2: Sum of angles of a triangle is 180°
⇒ 16° + 16° + ∠C = 180°
⇒ ∠C = 180 - 32 = 148°
Answer:
Calculate the unknown defining height, slant height, surface area, side length and volume of a square pyramid with any 2 known variables. ... e = lateral edge length r = a/2. V = volume. L = lateral surface area. B = base surface area The units are in place to give an indication of the order of the results such as ft, ft2 or ft3.
