Answer:
Step-by-step explanation:
Question 1. 50% of what number is 100?
Number = x
50%x = 100
5x/10 = 100 (50% = 2/10)
5x = 1000 (Multiplying by 10 at both sides of the equation)
<u>x = 200</u> (Dividing by 5 at both sides of the equation)
<u>Part 50 Whole 100 Part 75 Whole 150 Part 100 Whole 200</u>
Question 2. 25% of what number is 30?
Number = x
25%x = 30
x/4 = 30 (25% = 1/4)
x = 120 (Multiplying by 4 at both sides of the equation)
<u>Part 25 Whole 30 Part 50 Whole 60 Part 75 Whole 90 Part 100 Whole 120</u>
<u>Question 3. What did you differently to find the whole using a ratio table?</u>
Using a ratio table is a much more simple path to get the whole. I take it and just calculate the double of the information given to me for completing the next values in my table, until I get the part 100 and its correspondent whole.
C because its a line segment
Let's find the area of the base.
It's a rectangle that's 3.8 by 4.8, so let's multiply.
3.8×4.8=18.24
We have two different triangles.
Triangle one has a height of 2.6 and base of 4.8. But there are two of them.
2.6×4.8×0.5=6.24×2= 12.48; this is the area of two triangles.
Another set of triangles has a height of 2.9 and a base of 3.8.
2.9×3.8×0.5=5.51×2=11.02
Let's add all the areas together.
18.24+12.48+11.02
41.74
The surface area is 41.74 m², so the third option.
