(1) Ans: 19.1 m

Solution:

\frac{model}{actual} =  \frac{4}{x} \\  \frac{55.7}{265.4} =  \frac{4}{x} \\ x =  \frac{4*265.4}{55.7} \\ x = 19.1 m

(2) Ans: 1.7 ft

Solution:

\frac{map}{actual} =  \frac{1}{15.9} \\  \frac{x}{26.8} =  \frac{1}{15.9} \\ x =  \frac{1*26.8}{15.9} \\ x = 1.7 ft

(3) Ans: 2.3 mi

Solution:

\frac{map}{actual} = \frac{9}{3} \\ \frac{6.8}{x} = \frac{9}{3} \\ x = \frac{6.8*3}{9} \\ x = 2.3 mi


(4) Ans: 6.8 mi

Solution:

\frac{map}{actual} = \frac{2}{5} \\ \frac{2.7}{x} = \frac{2}{5} \\ x = \frac{2.7*5}{2} \\ x = 6.8 mi

(5) Ans: 4.0 ft

Solution:

\frac{map}{actual} = \frac{1}{13.7} \\ \frac{x}{54.9} = \frac{1}{13.7} \\ x = \frac{1*54.9}{13.7} \\ x = 4.0 ft

(6) Ans: 7.8 m

Solution:

\frac{model}{actual} = \frac{4}{x} \\ \frac{55.7}{108.4} = \frac{4}{x} \\ x = \frac{4*108.4}{55.7} \\ x = 7.8 m

(7) Ans: 1.5 mi

Solution:

\frac{map}{actual} = \frac{9}{2} \\ \frac{6.8}{x} = \frac{9}{2} \\ x = \frac{6.8*2}{9} \\ x = 1.5 mi

(8) Ans: 4.9 mi

Solution:

\frac{map}{actual} = \frac{4}{2} \\ \frac{9.7}{x} = \frac{4}{2} \\ x = \frac{9.7*2}{4} \\ x = 4.9 mi

(9) Ans: 36.0 m

Solution:

\frac{model}{actual} = \frac{6}{x} \\ \frac{24.5}{146.8} = \frac{6}{x} \\ x = \frac{6*146.8}{24.5} \\ x = 36.0 m

(10) Ans: 1.2 m

Solution:

\frac{map}{actual} = \frac{1}{16.5} \\
\frac{x}{19.5} = \frac{1}{16.5} \\ 
x = \frac{1*19.5}{16.5} \\ 
x = 1.2 m

(11) Ans: 4.9 mi

Solution:

\frac{map}{actual} = \frac{6}{6} \\ 
\frac{4.9}{x} = \frac{6}{6} \\ 
x = \frac{6*4.9}{6} \\ 
x = 4.9 mi

(15) Ans: 55.9 m</span>

Solution:

\frac{model}{actual} = \frac{9}{x} \\ &#10;\frac{32.9}{204.3} = \frac{9}{x} \\ &#10;x = \frac{9*204.3}{32.9} \\ &#10;x = 55.9 m<span>

(16) Ans: 2.5m</span>

Solution:

\frac{map}{actual} = \frac{1}{15.2} \\ &#10;\frac{x}{37.9} = \frac{1}{15.2} \\ &#10;x = \frac{1*37.9}{15.2} \\ &#10;x = 2.5 m
<span>
(17) Ans: 27.6 mi</span>

Solution:

\frac{map}{actual} = \frac{3}{9} \\ &#10;\frac{9.2}{x} = \frac{3}{9} \\ &#10;x = \frac{9.2*9}{3} \\ &#10;x = 27.6 mi
<span>
(18) Ans: 7.1 m</span>

Solution:

\frac{model}{actual} = \frac{5}{x} \\ &#10;\frac{64.9}{92.6} = \frac{5}{x} \\ &#10;x = \frac{5*92.6}{64.9} \\ &#10;x = 7.1 m<span>

(19) Ans: 4.2 m</span>

Solution:

\frac{map}{actual} = \frac{1}{10.2} \\ &#10;\frac{x}{42.8} = \frac{1}{10.2} \\ &#10;x = \frac{1*42.8}{10.2} \\ &#10;x = 4.2 m

Lisa's store collects 5% sales tax on every item sold. If she collected $22.00 in sales tax, what was the cost of the items her
Ede4ka [16]
Since we are looking for the principal amount, then all we have to do is reverse the process of getting the amount of tax. In order to get the principal, you just have to divide 22 with 0.05. The answer is 440 so that is the principal amount you are looking for.

If a car goes 280 miles in 4 hrs how far could it go in 6 hrs and 30 mins
Zina [86]

Answer:

280/4 = 70 miles per hour. Next, take the unit rate and multiply it by the number of hours you are trying to find. In this case, you are trying to find 6 hours and 30 minutes, but this can also be rewritten as 6.5, since 30 minutes is half an hour. So, in 6.5 hours, the car can go 455 miles

X-y=-3<br> I just kinda need the answer
bezimeni [28]

Just so you know, you have to know at least one of the variables to find out what the other is. Like for example, X could equal 2, so that would make y equal 5. Or X could equal 23, and that would make y equal 26.
