A)
360/20=18 (same for all the other value pairs)
p=18*t
b)
direct (inverse would be division not multiplication)
c)
18*40=720
Answer:
a) 42
Step-by-step explanation:
180-138=42
Answer:
The new coordinates are (-11, -35)
Step-by-step explanation:
When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.
Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm
Answer: 86
Step-by-step explanation:
Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.
Therefore, the equation to solve this will be:
= 2 + 6d
where,
d = number of days = 14 days
= 2 + 6d
= 2 + 6(14)
= 2 + 84
= 86
