3rd Option

Step-by-step explanation:

When you find the ratio of the 2 triangles, it is 14/5, so the 2nd option and 4th option are out of the park (The triangles are indeed similar). You are left with options 1 and 3. Option 3 is the best answer as you have to match the vertices of each triangle to each other.

Solve:

r
5
- 6 = -1

Answers

that's right, 5- 6= -1
If this is your question: 5r - 6 = -1 then keep reading

1) Write the question.
5r - 6 = -1

2) Bring the -6 to the other side by doing the inverse, +6 to both sides
5r = 5

3) Divide both sides by 5, to get the value of r
r = 1

The above is the answer :)

The correct way to write 1/4% as a decimal is 0.0025.

The reporter's likely error was that he did not notice the percent sign, thus saying that 1/4% is equivalent to 0.25.


Answer:

a. .0025   b. (see below)

Step-by-step explanation:

Percents are converted to decimals by moving the decimal 2 places to the left.


a. Write 1/4% as .25% Then, move the decimal two places to the left. You arrive at .0025.

b. The reporter's likely error is he/she thinking that 25 being 1/4 of one hundred, but it is not 1/4 percent of one hundred. It is 25% of one hundred.
