Answer:
Step-by-step explanation:
<u>Use the slope formula:</u>
10.
- m = (6.24 - 3.27)/(5 - 2) = 2.97/3 = 0.99
11.
- m = (240 - 360)/(3 - 1) = -120/2 = -60
12.
- m = (8.84 - 6.09)/(7 - 2) = 2.75/5 = 5.5
Answer:
The scale is 1:200
Step-by-step explanation:
On the plan we have the drawing as 6 cm
In real representation, we have the distance as 12 m
Firstly we have to convert to same unit
In this case, we use the cm for convenience
Mathematically, 100 cm is 1 m
Thus, 12 m
will be 12 * 100 = 1,200 cm
So, we have the ratio as;
6 cm : 1,200 cm
and that is 1:200 (since 6/1200 = 1/200 and in ratio form, we have that as 1:200)

Answer:
a=-36
Step-by-step explanation:
1/6(a+12)=-4
1) Distribute <u>1/6</u> to a and 12:
1/6a+2=-4
2) Subtract 2 from both sides:
1/6a=-6
3) Multiply both sides by the reciprocal of 1/6: (6/1)
a=-36
