Answer:
- The inequality should be s<270.
- The number line should be shaded to the left.
Step-by-step explanation:
Miche found that most helicopters fly at speeds of less than 270 kilometers per hour.
If s=speed of the helicopters
Representing this on a number line:
- We have an open circle at 270.
- Everything to the left of the circle is shaded.
Since the options are not given, I would list the mistakes made by Miche.
- The inequality should be s<270.
- The number line should be shaded to the left.
Answer:
D) Van: 7, Bus: 20
Step-by-step explanation:
Add the amount of students together (455 students in total)
Then I added the amount of buses and vans together (5 Vans and 21 Buses)
Then I plugged in each answer
5 x 7 = 35
455 - 35 = 420
420 / 21 = 20
The area of the composite figure from the image attached is 112.5 units²
<h3>What is the area of a composite figure?</h3>
The area of a composite figure refers to the sum total of all the areas of the shapes in that composite figure. This can be done by first identifying the shapes in that composite figure, then finding each area, followed by the addition of all the areas to determine the area of the composite figure.
From the given figure; we can break it down into:
- A parallelogram
- A rectangle
- A triangle
The area of a parallelogram = b × h
where;
- b & h refers to the length of the two opposite diagonal lines.
The area of a parallelogram = 9 × 6
The area of a parallelogram = 54 units²
The area of a rectangle = Length × breadth
The area of a rectangle = (9 × 3) units²
The area of a rectangle = 27 units²
The area of the triangle 
where;
The area of the triangle
The area of the triangle 
The area of the triangle 
Therefore, the area of the composite figure is:
= 54 + 27 + 31.5
= 112.5 units²

Mean = Average
Median = Middle
Mode = Most (the number that appears most)
Answer:
17/72
Step-by-step explanation:
Let's make this equation easier to read.
.5/36 + 16(1/72)
Start by remembering PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
This is the order in which you will solve the problem. So multiplication first, then division, and finally addition.
Multiply 16 and 1/72
16/1 x 1/72 multiply across to get 16/72 which can be reduced to 2/9.
Divide .5 (or 1/2) by 36. To do this, multiply by the reciprocal of 36
1/2 x 1/36 = 1/72
Your equation is now
2/9 + 1/72
Your common denominator is 72, so multiply top and bottom of 2/9 by 8.
16/72 + 1/72 = 17/72
