Answer:
a) The height of the image = 11.2 millimeters
b) The distance between the camera and her friend = 2.24 meters
Step-by-step explanation:
<u>Part A: find the height of the image:</u>
distance from the lens to the film = 24 millimeters
distance from the lens to the her friend = 3 meters = 3000 millimeters
height of her friend = 140 centimeters = 1400 mm
the height of the image = x
Using the similarity :
<u>Part B: find the distance between the camera and her friend</u>
If the height of the image on the film of her friend is 15 millimeters.
Let the the distance between the camera and her friend = y
V=1/3*3.14*300^2*300
V=28260000
Answer:
44m
Step-by-step explanation:
A = 
r² = 154
= 22/7 * r² = 154
= r² = 154 * 7/22
= r² = 49
= r = √49
= r = 7m
Perimeter of circle = 2r
= 2 * 22/7 * 7
= 44/7 * 7
= <u>44 m</u>

Answer:
Step-by-step explanation:
ST = w + 6,
PR = w
From the diagram given, we can deduce that PR is the midsegment of ∆QST. Therefore, according to the midsegment theorem:
PR = ½ of ST
Plug in the values into the equation and solve for w.
(distributive property of equality)
(subtraction property of equality)
(multiplication property of equality)
(subtraction property of equality)
Divide both sides by -1
