Problem A
When you use the term larger, you mean that (if the power is positive) the bigger number is in the numerator. 4*10^15 > 8 * 10^9 So 8 * 10^9 is in the denominator
Solution
Note:The tricky part is recognizing what to do with the 0.5 * 10^6. You can always break apart a power into it's parts. Since 6 = 5 + 1, the power can be broken down into 10^1*10^5. The 10^1 is used to get the 0.5 to a number that is a single digit.
Problem 2
I'm just going to give you the answer to this. Please use Problem A as a guide.
Answer:
Q1) 104m²
Q2) 121 in.²
Step-by-step explanation:
<em>Q1)</em>
<u>GIVEN :-</u>
- Figure given in the question comprises of a triangle & a rectangle.
- Length of the rectangle = 10 m
- Width of the rectangle = 8 m
- Base of the triangle = 8 m
- Height of the triangle = 6 m
<u>TO FIND :-</u>
<u>GENERAL FORMULAES TO BE USED IN THIS QUESTION :-</u>
- For a triangle with height 'h' & base 'b' , its area = .
- For a rectangle with length 'l' & width 'w' , its area =
<u>SOLUTION :-</u>
Area of the triangle =
Area of the rectangle =
Area of the figure = (Area of the triangle) + (Area of the rectangle)
= 24m²+ 80m²
= 104m²
<em>Q2)</em>
<u>GIVEN :-</u>
- Figure given in the question comprises of a triangle & a trapezium.
- Lengths of parallel sides of trapezium are 6 in. & 7 in.
- Height of trapezium = 20 - 3 = 17 in.
- Base of the triangle = 3 in.
- Height of the triangle = 7 in.
<u>TO FIND :-</u>
<u>GENERAL FORMULAES TO BE USED IN THIS QUESTION :-</u>
- For a triangle with height 'h' & base 'b' , its area = .
- For a trapezium with parallel sides whose lengths are 'a' & 'b' and height 'h' , its area =
<u>SOLUTION :-</u>
Area of the triangle =
Area of the trapezium =
Area of the figure = (Area of the triangle) + (Area of the trapezium)
= 10.5 in.² + 110.5 in.²
= 121 in.²
Answer:
Area=
Step-by-step explanation:
Perimeter of the rectangle= 100 feet
Let, the width of the rectangle be 'w'
Length=w+4
Perimeter=2(Length+width)
Length=w+4=23+4=27 feet
Area of a rectangle = Length*Width
Area=
Answer:
10,5
Step-by-step explanation:
We have the inequality:
We can solve it by dividing each side by 8:
Answer: x<=7 (Option A).
