Answer:

A) DC equals EC times AC all over BC.

Step-by-step explanation:

We know that:

DE\parallel AB

Then by corresponding angles:

\angle CAB\cong \angle CDE\text{ and } \angle CBA\cong \angle CED

So, by AA-Similarity:

\Delta CDE\sim \Delta CAB

Corresponding sides of similar triangles are in proportion. Hence:

\displaystyle \frac{DC}{AC}=\frac{EC}{BC}

By multiplying both sides by AC:

\displaystyle DC=\frac{EC\cdot AC}{BC}

DC is equal to EC times AC over BC.

Hence, our answer is A.

In this equation, we are given:

  • a variable, a letter, and a power
  • a variable, and a letter
  • a variable

They are all different, so there are 3 different terms in the equation

Best of Luck!

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every 1/24 of a minute. At this rate, how many gallons of g
kirill115 [55]

Answer:

5 gallons

Step-by-step explanation:

We can use ratios to solve

5/12 gallon        x gallons

----------------  = -------------------

1/24 minute       1/2 minute

Using cross products

5/12 * 1/2 = x *1/24

5/24 = x/24

Multiply each side by 24

24*5/24 = x/24*24

5=x

We can pump 5 gallons
