49 and 5/8. 100-50=50-3/8 is going to be 49 and 5/8.
Answer:
- 3.24 m²
- 156 cm²
Step-by-step explanation:
1.
Area of a parallelogram = base × height
The area of the parallelogram
= 2.7 × 1.2
= <u>3.24 m²</u>
2.
Try to divide the figure into 2 rectangles and find their areas.
The area of the larger rectangle
= 6 × (20-6)
= 84 cm²
The area of the smaller rectangle
= 12 × 6
= 72 cm²
The total area of the figure
= 84 + 72
= <u>156</u><u> cm²</u>
so what was the question again?
Answer:
Step-by-step explanation:
Hey there!
What you do is find how much was taken off and add that to the price
60*.2= 12
12 was taken off of the original price
Now add:
60+12= 72
So the regular price was $72
Options are not shown but…
A square has 4 equal length sides and a right angle
Or two equal length diagonals which are perpendicular
Or 4 right angled corners and two adjacent sides equal
Or perpendicular diagonals with the same midpoint
Using the last one…
Gradient of AC = (5 - 3)/(-3 - 3) = 2/-6 = -1/3
Gradient of BD = (7 - 1)/(1 - -1) = 6/2 = 3
-1/3 x 3 = -1 so AC and BD are perpendicular
Midpoint of AC = ((-3 + 3)/2 , (5 + 3)/2) = (0, 4)
Midpoint of BD = ((1 + -1)/2 , (7 + 1)/2) = (0, 4)
