1) first step
in first place you must to Know how many feets are in a mile, it is given at the exercise ( 5280 feet = 1 mile)
now Winston's wi-fi has a range of 1 1/2 miles, it is necessary to transform to mile, then 1 + 1/2 = 3/2
establish the following relation 1 mile ____ 5280 feet
3/2 mile _____ x feet
x = 3/2mile ×5280 feet/ 1 mile = 7920 miles this is the range of the Winston 's wi-fi
2 ) second step
in order to know the relation of proportion you must divide the largest amount between the lowest
7960/ 3920 = 2
3960/ 7960 = 1 / 2⇒ 2×3960 = 1×7960, it means that the signals have the relation of 1 : 2, then the value of the range of Winston's signal <em>is twice ( 2) </em>the value of the range of isaac's signal, therefore the value of ratio is 2
B=3 i believe but not positive
Answer:
86,400 yd^2
Step-by-step explanation:
9600 * (3)^2 = 86,400 yd^2
Answer:
a = -15
Step-by-step explanation:
multiply both sides by 3, then you get a = -15
A) This one has no solutions because the answer of the equation is 0=-1 which isn't true.
b) 6t-3=3t+6 ==> 3t=9 ==> t=3 This means that this has one solution.
c) 6 (2m-3)-3m=2m-18+m ==> 12m-18=2m-18+m ==> 9m=0 ==> m=0 so this one has no solutions.
d) 10+3y-2=4y-y+8 ==> 8+3y=3y+8 ==> 0=0 ==> Infinitely many solutions.
~Hope I helped!~
