Answer:
77.5
Step-by-step explanation:
For 0.30 for the first 50, just subtract 50 from 175, that leaves 125.
(An easy way to do this is think of quarters, 25+25=50 and 50+25=75 so all you have to do is subtract two 25s and you know it's 125)
Put the 125 to the side, and multiply 50 to 0.30, you get 15.
Then for 0.50 over 50 containers, multiply the remaining 125 with 0.50, you get 62.5.
Add 62.5 and 15 together, that gives you 77.5
Answer:
I only know the answer to part A. The triangles ARE similar and they ARE congruent.
Step-by-step explanation:
The big triangle has 75° and 60°.
The little triangle has 75° and 45°
75°+60°+45° = 180°
45° is the missing interior angle for the big triangle.
75°+45°+60° = 180°
60° is the missing interior angle for the little triangle.
Answer:first one is 2.8, second is 3.9

Answer:
14.29cm
Step-by-step explanation:
Height of the building=10cm
Angle of depression=60°
We are therefore asked to find the distance from the stone to the
the foot of the building;Therefore we use Tan ratio which is opp/adj;
Let the distance from the stone to the foot of the building be x;
10/x=Tan60°
10/x=1.7/1
We then cross multiply to get 1.7x=10
x=10/1.7
=10*10/1.7*10
=100/17
=14.29cm.
Answer:
-( 2x^2+6-4/x)
