To answer this we just need to set up a equation:-
895 - 669 - 100 = 126.
SO, after these transactions you will have $126 left.
Hope I helped ya!!
Answer:
The lateral surface is 120 , which agrees with the third answer option of the list.
Step-by-step explanation:
Notice that the prism has 5 equal lateral faces, which are all rectangles of eight 6". The width of the prisms can be obtained by using the fact that the perimeter of the pentagon is 20", which gives a side length of 20/5 = 4 " which is the same as the with of the lateral rectangles.
Then the lateral area of the prism is:
Lateral area= 5 (6" x 4") = 5 (24) = 120

Answer: 50 x
Step-by-step explanation:
The convex mirror in the park is an illustration of lens magnification
The man must focus his eyes at 4.50 meters to see his image
<h3>How to determine the object distance?</h3>
The given parameter is:
Radius of curvature, r = 3.00 m
The magnification (m) of the mirror is 1/2, because the image (v) is half as tall as the actual height (u).
So, we have:
m = u/v
So, we have:
u/v = 1/2
Make v the subject
v = 2u
The focal length is calculated as:
1/f = 1/u + 1/v
The focal length is calculated as:
f = r/2
f = 3/2
Substitute f = 3/2 in 1/f = 1/u + 1/v
2/3 = 1/u + 1/v
Substitute v = 2u in 2/3 = 1/u + 1/v
2/3 = 1/u + 1/2u
Take the LCM
2/3 = (2 + 1)/2u
This gives
2/3 = 3/2u
Take the inverse of both sides
3/2 = 2u/3
Cross multiply
2u = 3 * 3
4u = 9
Divide both sides by 4
u = 9/4
This gives
u = 2.25
Recall that:
v = 2u
So,we have:
v = 2 * 2.25
v = 4.50
Hence, the man must focus his eyes at 4.50 meters to see his image
