I believe 67 is the correct answer
Answer:
first one
Step-by-step explanation:
These line equations are all of the form y = mx + b where m is the slope
if m = slope perpindicular m = - 1/m
The only one that fits this description is the first one
slope = 1/5 perpindicular = - 1/(1/5) = -5
Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet
Answer:
95 cm^2
Step-by-step explanation:
Answer:
3^5
Step-by-step explanation:
there are eight 3's as the numerator and three 3's as the denominator.
You will cancel out three of the 3's in the numerator with the ones on the denominator which gives you 3^5.
