Answer:
area = 54 mi²
Step-by-step explanation:
1 in = 3 mi
1 in x 1 in = 3 m²
3 mi²
18 in² = --------
1 in²
area = 18 * 3
area = 54 mi²
Answer:
y = 9
Step-by-step explanation:
The line x = -7 is a vertical line, so the perpendicular line will be horizontal.
Horizontal lines have a slope of 0.
Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation
y = mx + b
9 = 0(4) + b
9 = b
Plug this and the slope into the equation:
y = mx + b
y = 0x + b
y = 9
So, y = 9 is the equation
We would subtact 3 from both sides allowing the equation to simplify to -8c=32
We would then divide both sides by -8 to equal -4
The final answer C=-4
The value of the expression (6¾) × -11.5 is; -77⅝
We want to find the value of;
(6¾) × -11.5
Let us change 6¾ to improper fraction to get;
27/4
Also,let's change -11.5 to an improper fraction to get; -115/10
Thus;
(6¾) × -11.5 = 27/4 × -115/10
>> (-115 × 27)/(40)
>> 3105/40
>> -77⅝
