PLEASE HELP I’M SO CONFUSED

Mathematics
1 answer:
bekas [8.4K]3 years ago
5 0

Answer:

a. $45 an hour

b. 5.25 hours

Step-by-step explanation:

a. The plumber charges $75 per job, so it is irrelevant to the number of hours they work. 45(h) is $45 multiplied by the number of hours they work.

b.

First, plug the numbers into the equation, the cost being C(h):

311.25 = 45(h) + 75

Next, subtract $75 as it is a set price that is always payed:

236.25 = 45(h)

Then, divide both sides by 45 to find how many hours were worked:

h = 5.25

Hours = $5.25

DENIUS [597]

Answer:

Step-by-step explanation:

I have to say that there is not enough givens to prove anything. If the statement given is all there is, then many things can be proven.

One

All you are given is that the diagonal is bisected. It does not mean that the other diagonal is bisected without more information. All you can prove is that DH = HF                   Definition of a midpoint.

Two

For the second one KO bisects JKM. What that means is that the two smaller angles are equal. Bisects means cuts in half.

JKO = KOM. KO cuts JKM in half The reason is definition of bisect.

Three

This one actually can prove some something.

AB = BC   which equals AC

BC = CD  which equals BD

Therefore AC = DB

This is the associative property of equality. So far it is the hardest one.

Four

DE perpendicular to EF

Join DF                                                A triangle is formed by construction.

Triangle DEF   if s a right triangle.     Perpendiculars form right angles.

Hey Please help I have no idea what the answer is
Alexxandr [17]

Answer:

24

Step-by-step explanation:

This is a right triangle so you know the bottom right angle is 90 degrees.This is geometry it seems so left side you are given the numerical value 114 and as you know a straight line in correlation with shapes usually means its 180 degrees so 180-114 is 66 so that means the bottom left angle is 66 the bottom right is 90 and since a triangle sums up to 180 degrees you subtract the 2 angles from 180 to get 24
