8_murik_8 [283]

Answer:

rational

Step-by-step explanation: because the decimal terminates, it is necessarily rational - specifically, rational with a denominator that is a power of 10. Thus 1.3 = 13/10, 0.5761 = 5761/10000, and

1.2731568 = 12731568/10000000.

A surveyor is conducting measures to see how wide a road is

drek231 [11]

Answer:

D) 45 ft

Step-by-step explanation:

The two triangles are shown below.

Given:

BC = 60 ft, CD = 24 ft and DE = 18 ft.

Since, the two triangles are similar, their corresponding sides are in proportion.

So, $\frac{AB}{DE}=\frac{BC}{CD}=\frac{AC}{CE}$

Now, consider the proportion of sides,

$\frac{AB}{DE}=\frac{BC}{CD}\\AB=\frac{BC}{CD}\times DE\\AB=\frac{60}{24}\times 18\\AB=\frac{60\times 18}{24}=45\ ft$

Therefore, the distance between A and B is 45 ft.

A student's course grade is based on one midterm that counts as 20% of his final grade, one class project that counts as 20%

Rus_ich [418]

Answer:

His overall final score is 80.1.

His letter grade is a B.

Step-by-step explanation:

To find his grade, we multiply each grade by it's weight.

Grades and weights:

His midterm score is 64. The midterm counts 20% = 0.2.

His project score is 80. The project score counts 20% = 0.2.

His homework score is 94. The homework score counts 30%.

His final exam score is 77. It counts 30%.

What is his overall final score?

64*0.2 + 80*0.2 + 94*0.3 + 77*0.3 = 80.1

His overall final score is 80.1.

What letter grade did he earn (A, B, C, D, or F)?

At least 80 but less than 90 is a B. He scored 80.1, so his letter grade is a B.
