Answer:

53.0

Step-by-step explanation:

How we get the answer:

the complement of the question proposed one of the choices given beneath:

a) 58.8

b) 53.0

c) 29.4

d) 26.5

as we observe at the figure, AOB an isosceles triangle, and OCB is a right triangle

consider OCB

OC =9, OB= radius = 28

the problem is how to find the length of CA, for that C is a midpoint of segment AB, so AC=BC

BC can be found by using pythagorean theorem

OB²= OC² + CB²,  this implies CB² = OB² - OC²

CB² = 28² - 9² = 784 - 81=703, therefore CB= sqrt (703)=26.51

CB=26.51, since CB= AC, so  AC=CB= 26.51

finally the the length of AB is AB = 2 x CB = 2x AC= 2x 26.51= 53.0

the answer is b) 53.0

A train leaves Los Angeles at 2 p.m. heading north at 50 mph. If the next train leaves three hours later and also heads north at
Mamont248 [21]
Since the first train has been travelling for 3 hours, we have the following equations:
d=50t+3*50=50t+150
d=60t

We want to know when they will be equal, so set these equal to eachother:
60t=50t+150
10t=150
t=15

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.

There is a type of ammo in f/o/r/t/n/i/t/e that can be magically used for every single gun. You open an ammo box, and out pops 141 rounds of that ammo. You have already collected 6 guns. How many rounds go into each gun?

The answer is 23.5

THERE IS A REMAINDER??

Nothing happens! Literally! It never happened! There is no ammo that can be used for all the guns. GG and hope to see you on the game sometime, cause...i am not allowed to have it.

snow_tiger [21]

Answer:4x^2+22x-12

Step-by-step explanation:

height=(2x+12)

base=(4x-2)

Area of =(base x height)/2

Area of =((4x-2)(2x+12))/2

Area of =(8x^2+48x-4x-24)/2

Area of =(8x^2+44x-24)/2

Area of =4x^2+22x-12
