We know that
scale =measure in the map/measure in the actual
measure in the actual=measure in the map/scale
scale=1 cm/ 80 mi
for
measure in the map=7.5 cm
measure in the actual=?
measure in the actual=7.5 /(1/80)-----> 7.5*80-----> 600 mi
the answer is
<span>the actual distance between the two cities is 600 miles</span>
Answer:
x = 52.2
Step-by-step explanation:
we have adjacent (56) and opposite (x) so we use tan (Toa = opposite/adjacent).
Set up like so:
tan 43 = x/56
x = 52.2208
x = 52.2
Answer:
9
Step-by-step explanation:
Using the property that

Answer:
x=-12,y=3
Step-by-step explanation:
1/2x+6y=12
y=x+15
since y=x+15
substitute y in first equation, we have
1/2x+6(x+15)=12
open the bracket
1/2x+6x+90=12
1/2x+6x=12-90
x/2+6x= -78
13x/2=-78
13x=2×-78
x=-12
Now x=-12, put x=-12 in the second equation, we have
y=x+15
y=-12+15
y=3
