Answer: 8/343
Step-by-Step:
If two similar solids have a scale factor of a:b then,
The ratio of their surface areas (2D) is- a^2:b^2
The ratio of their volume (3D) is- a^3:b^3
First you want to square root the scale factor numbers to find the original value. Then you cube the original numbers to find the answer.
Answer:
1 dollar is equal to 0.75 E
Step-by-step explanation:
120$ = 90 e -----> 4$ = 3E
250$ = 187.50 e -----> 4$ = 3E
400$ = 300 e -----> 4$ = 3E
----------------------------------
from this we know 4$ = 3E
1 E = 4$/3
1 E = 1.33...$
---------------------
1 $ = 3/4 E
1 $ = 0.75 E
---------------------
1.33...$ dollars is equal to 1 E and
1 $ is equal to 0.75 E
-----------------------------------
90 x 1.33... =120
187.50x1.33...= 250
300 x 1.33... = 400
--------------------------
Answer:
Step-by-step explanation:
All the interior angles are of measure 60 degrees.
We want to find the height of this triangle. Call it h. On the left side of this illustration is a right triangle with height h and base (1/2)(10), or 5.
The ratio of height to base is the tangent of 60 degrees:
h
tan 60 degrees = --------------
5
h
and tan 60 degrees = 1.73 = ------
5
Multiplying both sides of this equation by 5 yields h = 8.66. This is |BD|. This is the same as Answer B.
