What is the perimeter of abc with vertices A(-2,9) B(7,-3) and C(-2,-3) in coordinate plane

Answers

Answer 1

Answer: For the answer to the question above,
A - C = ( -2, 9) - (- 2 -3)

= ( 0, 12)

AC = 12

B - C = (7 - 3) - ( - 2 -3)

= (9, 0)

BC = 9

ABC is a right -angled triangle with AC as the hypotenuse

AC = sqrt( 9^2 + 12^2)

= sqrt(81 + 144)

= srqt(225)

= 15

Perimeter = 12 + 9 + 15

= 36 units

So the answer is 36 units

There are 60 tables in a restaurant, with 25% of them seating 22 people. The tables remaining seat 44 people. How many seats are there in the restaurant?

Answers

find how many seat 22 people
25% of 60=1/4 times 60=15 tables

60-15=45 tables that seat 44

number of seats=22 times number of 22tables+44 times number of 44tables
number of seats=22 times 15+44 times 45
number of seats=330+1980
number of seats=2310 seats

Explain how you can use a straightedge and a compass to construct and angle that is both congruent and adjacent to a given angle?

Answers

Explain how you can use a straightedge and a compass to construct and angle that is both congruent and adjacent to a given angle?

Answer: for this you will simply have to use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.

I hope it helps, Regards.

Let's say x is the given angle

with compass point at A , draw a large arc cutting the line at C

then place compass at point c and draw a small arc through D

Then keeping the compass point at C, draw a similar small arc at E

Join A and E with straight edge

hope this helps

Write a rule for a geometric sequence that has -6 as its first term and a common ratio of 2. What is the tenth term of this sequence?A) A(n) = 2 * -6^10-1; -20,155,392
B) A(n) = -6 * 2^n; -6144
C) A(n) = -6 * 2^n-1; -3072
I need this Answered ASAP, Thank you

Answers

The general form of the geometric sequence is $a_(n) = a_(1) (r) ^(n-1)$ , where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1. Our formula then looks like this: $a_(10) =-6(2) ^(10-1)$ . Simplify it to $a_(10) =-6(2)^9$ . Take 2 to the 9th power then multiply it by -6 to get -3072. C is your answer.

Ling works as a pharmacy technician. She is paid $11.50 for every hour she works. She can calculate her earnings by using the equation t=11.50h, where t represents her total pay and h represents her hours worked. How much money will Ling earn if she works for 13 hours? How much money will Ling earn if she works for 13 hours each week for 5 weeks?

Answers

If you would like to know how much money will Ling earn if she works for 13 hours (and for 13 hours each week for 5 weeks), you can calculate this using the following steps:

t = 11.50 * h
t ... total pay
h ... hours worked

h = 13 hours
t = 11.50 * h = 11.50 * 13 = $149.5
Ling will earn $149.5 for 13 hours.

5 weeks * $149.5 = $747.5
Ling will earn $747.5 if she will work for 13 hours each week for 5 weeks.

Answer:

Ling will earn $747.5 if she will work for 13 hours each week for 5 weeks.

It takes omar four minutes to eat eight carrots sticks. how long does it take him to eat one ?

Answers

It takes Omar 30 seconds to eat one considering he ate 8 in 4 minutes ...

If we really wanted to we could turn this into the fraction 8/4
8 being the amount of carrot sticks he ate and 4 being the time it took
now all u have to do is simplify that turns into 2/1 and since the 1 is one minute and her can eat 2 in one minute we can safely say he eats 1 carrot stick every 30 seconds
