In triangle NQL, point S is the centroid, NS = (x + 10) feet, and SR = (x + 3) feet. Triangle N Q L has centroid S. Lines are drawn from each point to the midpoint of the opposite side to form line segments N R, Q M, and L P. The length of line segment N S is x + 10 and the length of line segment S R is x + 3.

What is RS?

4 feet
7 feet
10 feet
14 feet

Answer 1

Answer:

B. 7 feet

Step-by-step explanation:

Given:

NS = (x + 10) ft

SR = (x + 3) ft

Required:

SOLUTION:

Based in the centroid theorem, the centroid, S will divide the median, line segment NR, into NS and SR, such that NS : SR = 2 : 1.

Therefore:

NS = 2(SR)

x + 10 = 2(x + 3) (substitution)

Solve for x

x + 10 = 2x + 6

Collect like terms

x - 2x = -10 + 6

-x = -4

divide both sides by -1

x = 4

SR = (x + 3) ft (SR is same as RS)

Plug in the value of x

SR = (4 + 3) ft

SR = RS = 7 ft

Fred works for $8.75 per hour. His regular hours are 40 hours per week and he gets time and a half for overtime. One week he works 47.5 hours. He wants to calculate his pay.

Answers

For the first 40 hours, he gets 8.75/hour, so 40*8.75 = 350. For the last 7.5 hours, he gets (8.75*1.5)/hour. 8.75*1.5 = 13.125/hour, or 13.13/hour. Then do 13.13/hour * 7.5 hours = 98.48. Now add together 350 and 98.48. That equals $448.48 total for the week

Answer:

350, 13.13/hour, 98.48, 448.48.

When graphing an inequality how do you know whether the line should be solid or dotted? plz go into detail and if you have a specific way your remember it plz help i need it for my final exam.

Answers

well, when it comes to graphing an inequality, and you need to know whether the line is solid or dashed, look at the inequality sign..... (i do not remember that exact terms) anyway, if it is JUST > or < then it is dashed, that is because you are not including that number, just any number greater than or less than it...

however, if it is Greater than or Equal to
or
less than or equal to
where these two are including that # by having the "or equal to", it will be solid for it is INCLUDING what ever # we are using...

for example

y > 3 will be dashed

where as y is greater than or equal to 3 will be solid since the y could be 3

i cant really explain this well... but i hope i made it somewhat clear

abby owns a square plot of land. she knows that the area of the plot is between 2200 and 2400 square meters. which of the following answers is a possible value for the side length of the plot of land?

Answers

Answer:

Step-by-step explanation:

The formula for the area of a square is A = s². Plug in each value and see if is in between 2200 and 2400.

A = s²

A = (46)²

A = 2116

A = s²

A = (48)²

A = 2304

A = s²

A = (50)²

A = 2500

A = s²

A = (44)²

A = 1936

The only value that fits in between 220 and 2400 is 48.

Can anyone help me choose the correct answer?!
