If triangles AMN and ABC are similar, then

AM/AB = AN/AC

or

AM/(AM + MB) = AN/(AN + NC)

Check if this is true:

AM/AB = 21/(21 + 9) = 21/30 = 7/10

AN/AC = 14/(14 + 6) = 14/20 = 7/10

The angle at vertex A is common to both of the triangles.

Then by the side-angle-side (SAS) similarity theorem, the triangles are indeed similar.

You pawn a guitar and receive $880. One month later, you get the guitar back by paying $1250. If this is simple interest, then w
Lemur [1.5K]
Interest=1250-880=370
I=PRT
P=principal
r=rate in deicmal
t=time in years

1 month so t=1/12
P=880
I=370

370=880*r*1/12
370=220/3r
times both sides by 3
1110=220r
divdie both sides by 220
5.04545=r
505% interest

Mr Smith is on a road trip from Cleveland to Chicago. He is 65% of the way there , and has already driven 455 miles. How many mo
Keith_Richards [23]
Hi i'd be glad to help you with this equation. 

basically all we have to do is find (65%) of 455*. 

65% of 455* = 295.75 

Next. 

455 + 295.75 = 750.75 

So, to check my work I have 750.75 miles in total. 

I have already driven 455 miles of 750.75 miles. 

Using subtraction we subtract our distance from our total. 

750.75 - 455 = 295.75 

So, in total your answer to this problem is (295.75) 

Hope this helps. 
Have a great day!

The step most likely to follow this is 2x = 25 because you next want to add 5 to both sides.

Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's
Anuta_ua [19.1K]

Answer:

Option C.

Step-by-step explanation:

It is given that the ball's height, in feet, is modeled by the function

f(x)=-x^2-x+3

where, x represents time in seconds.

We need to find the height of the ball when Sarina throws it. It means, we need to find the initial height of the ball.

Substitute x=0 in the given function, to find the initial height.

f(0)=-(0)^2-(0)+3

f(0)=0+0+3

f(0)=3

The height of the ball is 3 feet when Sarina throws it.

Therefore, the correct option is C.
