A student receives his grade report from a local community college, but the GPA is smudged. He took the following classes: a 2 h

our credit art, a 3 hour credit history, a 4 hour credit science course, a 3 hour credit mathematics course, and a 1 hour science lab. He received a "B" in the art class, an "A" in the history class, a "C" in the science class, a "B" in the mathematics class, and an "A" in the science lab. What was his GPA if the letter grades are based on a 4 point scale? (A=4, B=3, C=2, D=1, F=0)
A. 2.7
B. 2.8
C. 3.0
D. 3.1

Answer:

  • C. 3.0

Step-by-step explanation:

<u>Lets calculate the points:</u>

  • Art - 2 hrs - B (3)                ⇒ 2*3 = 6 points
  • History - 3 hrs - A (4)         ⇒ 3*4 = 12 points
  • Science - 4 hrs - C (2)       ⇒ 4*2 = 8 points
  • Math - 3 hrs - B (3)            ⇒ 3*3 = 9 points
  • Lab - 1 hr - A (4)                 ⇒ 1*4 = 4 points

<u>Totals</u>

  • Total hours = 13            
  • Total points = 39

<u>GPA = total points/ total hours</u>

  • GPA = 39/13 = 3.0

Correct option is C

Answer: The correct statements are 'The equation 2n = p should be 2p = n' , 'The actual cost of the onions is $3.00 per pound' and 'Potatoes cost $1.50 per pound.'

Step-by-step explanation:

Here, p represents cost of one potato and n represents the cost of one onion.

And, According to the question,  He purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18.

Therefore, 6p +3n = 18    ------(1)

And, Onions cost twice as much as potatoes.

Therefore, n= 2p ---------(2)

Putting the values of n from 2) in equation 1),

we get, 6p+3(2p)=18

⇒6p+6p=18 ⇒ 12p =18 ⇒ p = 1.5 dollar.

Thus cost of one potato= $1.5

And cost of one onion = $ 2× 1.5= $ 3.00

Thus with help of above explanation we can say that Options first, third and fifth are correct.

On a coordinate grid, AB has an end point B at (24, 16). The midpoint of AB is P(4, -3). What is the y-coordinate of Point A?
inysia [295]

The y-coordinate of point A is -22

Step-by-step explanation:

Given

B = (24,16)

P = (4,-3)

The formula for mid-point of AB will be given by:

P = (\frac{x_A+x_B}{2} , \frac{y_A+y_B}{2})

As we already know the y-coordinate of midpoint

We can put the formula's y coordinate equal to the given value

\frac{y_A+y_B}{2} = -3\\\frac{y_A + 16}{2 } = -3\\y_A+16 = -3 * 2\\y_A +16 = -6\\y_A = -6-16\\y_A = -22

Hence,

The y-coordinate of point A is -22

A skateboard travels 55 feet in 4 seconds. Is the skateboard going faster, slower, or the same speed as the scooter?
Assoli18 [71]

Answer:

Slower.

Step-by-step explanation:

I belive it is slower because the scooter was 30 feet per 2 seconds. 30+30+60 feet, 2+2= 4 seconds= 60 feet and 4 seconds which makes the 55 feet per 4 seconds slower.

How do I work this out?
zvonat [6]

We have to determine the value of \sum _{m=9} ^{21} (5m+6)

= (5(9)+6) + (5(10)+6) +(5(11)+6) + .......... + (5(21)+6)

= 51+56+61+66+ ........ + 111

Since, the common difference is 5, hence this series is in arithmetic progression.

Sum of AP is given by the formula:

\frac{n}{2}[2a+(n-1)d]

Since, there are 13 terms.

= \frac{13}{2}[2(51)+(13-1)5]

= \frac{13}{2}[102+60]

= \frac{13}{2}[162]

= 13 \times 81

= 1053

Therefore, the sum of the series is 1053.

So, Option G is the correct answer.
