What are all names for pi over 2

Lyrx [107]

All the names for the mathematical statement given as pi over 2 are π/2 rad and 90 degrees

<h3>How to determine all the names for pi over 2?</h3>

The mathematical statement is given as:

All names for pi over 2

Rewrite the mathematical statement as follows:

All names for pi/2

This can further be rewritten as:

All names for π/2

In the measurements of angles.

The value of π is 180 degrees

So, we have

π/2 = 180 degrees/2

Evaluate the quotient

π/2 = 90 degrees

Hence, all the names for the mathematical statement given as pi over 2 are π/2 rad and 90 degrees

I need help with this

Dafna11 [192]

Answer:

x = -9

Step-by-step explanation:

The attachment shows the labeling according to the problem statement.

The overall length is the sum of the constituent segment lengths, so ...

FG + GH = FH

(10 +x) +(7) = (2x +26)

x +17 = 2x +26

x -9 = 2x

-9 = x

<em>Check</em>

Then the segment length FG is ...

10 +x = 10 -9 = 1

and the overall length is ...

2x +26 = 2(-9) +26 = -18 +26 = 8

That is, 1 + 7 = 8.

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.
