To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of

tia_tia [17]

Answer:

2.89, rounded to the nearest hundredth

Step-by-step explanation:

Given that GPA is weighted by credits, we must first multiply each grade by its credit amount and sum those up to weigh the credits. Then, we divide by the total amount of credits to get the GPA per credit.

So, we start with math,

3.7 *5 + 1.8 *3 + 2.8 * 5 + 2.8 * 4 = 49.1 as the total GPA weighted per credit.

Then, to find the average per credit, we divide by the total amount of credits, which is 5 + 3 + 5 + 4 = 17.

Our answer is 49.1/17 = 2.89, rounded to the nearest hundredth

PLZ HELP 10 PTS!!

Answer:

Jill's best friend jumped 8/21 feet further than Jill.

Step-by-step explanation:

we have that

Jill jumped 6 1/3 feet

Jill best friend jumped 6 5/7 feet

To find out how much farther did Jill's best friend jumped, subtract the length that Jill jumped from the length that Jill best friend jumped

$6\frac{5}{7}-6\frac{1}{3}$

but first convert mixed number to improper fraction

$6\frac{5}{7}\ ft=\frac{6*7+5}{7}=\frac{47}{7}\ ft$

$6\frac{1}{3}\ ft=\frac{6*3+1}{3}=\frac{19}{3}\ ft$

substitute the values

$\frac{47}{7}-\frac{19}{3}=\frac{47*3-7*19}{21}=\frac{8}{21}\ ft$

therefore

Jill's best friend jumped 8/21 feet further than Jill.

NEED HELP ASAPInstructions: Find the length of the missing sides. Round your answers to the

Pie

Answer:

$x = 9.4$

$y = 17.7$

Step-by-step explanation:

Given: The figure

Required: Find x and y

The relationship between length x, length 15 and angle 32 is as follows:

$tan \theta = \frac{opp}{adj}$

So, we have:

$tan\ 32= \frac{x}{15}$

Cross multiply:

$x =15*tan\ 32$

$x = 15 * 0.6248693519$

$x = 9.3730402785$

$x = 9.4$ --- approximated

Similarly:

The relationship between length y, length 15 and angle 32 is as follows:

$cos \theta = \frac{adj}{hyp}$

So, we have:

$cos\ 32= \frac{15}{y}$

Cross Multiply:

$y * cos\ 32= 15$

Solve for y

$y = \frac{15}{cos\ 32}$

$y = \frac{15}{0.84804809615}$

$y = 17.6876760506$

$y = 17.7$ --- approximated

Which operation will cancel out division?

emmasim [6.3K]

Answer:

The operation that will cancel out division is multiplication.

Step-by-step explanation:

For example:

$\frac{2+5x}{2} \\$

*in order to solve for x, and get the upper equation without division, you must multiply by the negative reciprocal*

$2*(\frac{2+5x}2} )$

$4+10x\\$

*to get x alone, we must subtract 4 from both sides*

$10x = -4\\\\-4 / 10 = - 2/5$

$x=- 2/5$
