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.

A cyclist rides 225 m each minute.About how long does it take to ride 15km? Show all fo your work

Elan Coil [88]

Speed = 225 metres per minute

Distance = 15 km = 15,000 metres

---------------------------------------------------

s=d/t

ts=d

Therefore: t=d/s

--------------------------------------------------

Time = Distance / Speed

Time = (15,000 metres) / (225 metres per minute)

--------------------------------------------------

Let's work it out:

$Time=\frac { 15,000\quad metres }{ \frac { 225\quad metres }{ 1\quad minute\left( s \right) } } \\ \\ =\frac { 15,000\quad metres }{ 1 } \cdot \frac { 1\quad minute\left( s \right) }{ 225\quad metres } \\ \\ =\frac { 15,000 }{ 225 } minutes$

$\\ \\ =\frac { 200 }{ 3 } minutes\\ \\ \frac { 200 }{ 3 } minutes\quad =\quad 66\quad minutes,\quad 40\quad seconds$
