Answer:

a = 14 km

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh  where b is the base and h is the height

112.7 = 1/2 ( a) 16.1

112.7 = 8.05a

Divide each side by 8.05

112.7/8.05 = a

14 =a

The scale on a map of Virginia shows that 1 centimeter represents 30 miles. The actual distance from Richmond, VA to Washington,
Leya [2.2K]
The ratio of cm to mi is 1/30, and we are looking for x/110. Since 1/30 = x/110, 30x=110.
x = 110/30 = 11/3 = 3.7 cm

one half the cost of a dress decreased by $12 is the same as 2/5 the cost of a dress. What is the cost of the dress?
guajiro [1.7K]

Answer:

$120

Step-by-step explanation:

Let the cost of the dress be "c"

ONE HALF the cost DECREASED by 12, can be written as:

\frac{1}{2}c-12

2/5th the cost of dress, can be written as:

\frac{2}{5}c

Now, we equate both parts and solve for c to get cost of dress. Shown below:

\frac{1}{2}c-12=\frac{2}{5}c\\\frac{1}{2}c-\frac{2}{5}c=12\\\frac{5-4}{10}c=12\\\frac{1}{10}c=12\\c=\frac{12}{\frac{1}{10}}\\c=12*10\\c=120

Thus,

The ccost of the dress is $120

For each input (number), there is exactly ONE output.  So the given table does represent a function.


If  <span>f(x)=925x+1000 and x=24, then f(24) = 925(24)+1000 = 23200.</span>
