The length of the subway is 850 miles. If .15 inch represents 45 miles, what is the length of the subway on the map?
Scilla [17]

Answer:

The length of the subway on the map is 2.83\ inches

Step-by-step explanation:

we know that

The scale on the map is equal to the length of the subway on the map divided by the length of the subway in the actual

so

Let

z------> the scale on the map

x------> the length of the subway on the map

y------> the length of the subway in the actual

z=\frac{x}{y}

In this problem we have

z=\frac{0.15}{45}\frac{inches}{miles}

y=850\ miles

substitute and solve for x

\frac{0.15}{45}=\frac{x}{850}

x=850*\frac{0.15}{45}=2.83\ inches

A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx
tester [92]

Answer:

b=-18

Step-by-step explanation:

If a line that passes through the point P(x_o,y_o)and it has slope m, the equation of the line is:

y-y_o=m(x-x_o)~=>y=mx+y_o-mx_o~=>b=y_o-mx_o\\\\b=-6-4(3)=-18

Is it possible for a 5 digit number to be rounded to a 6 digit number
IrinaK [193]
When we round a number the new rounded <span>number is </span>simpler but the value is kept close to what it was. The common method for rounding numbers is the following: we d<span><span>ecide which is the last digit to keep and l</span><span>eave this digit the same the same if the next digit is less than 5 or increase it by 1 if the next digit is bigger than 5.
</span></span>Because the next digit matter, it is not possible for a 5 digit number to be rounded to 6 digit number.
