Hey there! :)
Answer:
16 m².
Step-by-step explanation:
Find the surface area by finding the areas of each face:
The base is a square, so use the formula A = s²
A = 2²
A = 4 m².
Find the areas of the congruent triangular lateral sides. Use the formula:
A = 1/2 (bh)
A = 1/2 (2 · 3)
A = 1/2 (6)
A = 3 m².
There are 4 triangular faces, therefore:
3 × 4 = 12 m².
Add up the areas from the triangles and square base:
12 + 4 = 16 m².
Therefore, the surface area of this square pyramid is 16 m².
Answer:Tables are used to organize exact amounts of data and to display numerical information. Tables do not show visual comparisons. As a result, tables take longer to read and understand. It is more difficult to examine overall trends and make comparisons with tables, than it is with graphs.
Line graphs are used to display data or information that changes continuously over time. Line graphs allow us to see overall trends such as an increase or decrease in data over time.
Bar graphs are used to compare facts. The bars provide a visual display for comparing quantities in different categories or groups. Bar graphs help us to see relationships quickly. However, bar graphs can be difficult to read accurately. A change in the scale in a bar graph may alter one's visual perception of the data.
Circle Graphs are used to compare the parts of a whole. Circle graphs represent data visually in the same proportion as the numerical data in a table: The area of each sector in a circle graph is in the same proportion to the whole circle as each item is to the total value in the table. Constructing an accurate circle graph is difficult to do without a computer. This is because you must first find each part of the whole through several elaborate calculations and then use a protractor to draw each angle. This leaves a lot of room for human error. Circle graphs are best used for displaying data when there are no more than five or six sectors, and when the values of each sector are different. Otherwise they can be difficult to read and understand.

Answer:
The rate at which bracelet maked is 27.3
Step-by-step explanation:
Given as :
The number of bracelets sold on Monday = 12
The number of bracelets sold on Tuesday = 22
The Time period of work on Tuesday = 2.5 hours
Now,
The quantity of bracelets after n hours = Initial quantity of bracelets × 
Or, The number of bracelets sold on Tuesday = number of bracelets sold on Monday × 
Or, 22 = 12 ×
Or, 
=
Or, 1.83 =
Or, 
= 1 + 
Or, 1.273 - 1 =
Or, 0.273 × 100 = Rate
∴ Rate = 27.3
Hence The rate at which bracelet maked is 27.3 Answer
Answer: Not 100% sure, but i think it's 3j + 1...?
