Answer:
18 in
Step-by-step explanation:
A = (1/2)bh
A = 54 in
b = 12/2 = 6 in
making h the subject
h = 2A/b
h = (2×54) ÷ 6
h = 108/6
h = 18 in
Answer:
Line b and line c are perpendicular.
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, and -1/2 and 2 are opposite reciprocals.
Remember that slope is Δy/Δx
We are looking for a table where the y values are decreasing by a factor of 3, and the x values are increasing by a factor of 2.
Table 2 fits this description.
The second table is correct.
Answer:
p = 12/18
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
8/9*p-(12/18)=0
