We are given triangles QRS and DEF.
QR = DE and SR = FE.
Also we are given angle < R = 62 degrees and angle < E = 50 degrees.
<R is greater than the < E.
Note: Corresponding side of smaller angle is small.
<em>In triangle QRS, < R is greater angle than the <E in triangle DEF.</em>
Therefore, side DF is smaller side of QS.
<h3>Therefore, correct statement is B. DF < QS .</h3>
Answer:
16 the answer
Step-by-step explanation:
Let x = 30% y=16%
We need 5 liters of 27.2% acid
A) x + y = 5
B) .30 x + .16y = 5 * .272
Multiplying A by -.30
A) -.30 x - .30y = -1.5 then adding to B
B) .30 x + .16y = 1.36
-.14y = -.14
y = 1 liter 16%
x = 4 liters 30%
Area of the base and the top :(4x7) + (4x7) = 56
Lateral area of the front & the back = (4x12) + (4x12) = 96
Lateral area of the right & left = (7x12) + (7x12) = 168
TOTAL AREA = 56+96+168 = 320
Volume = 4x7x12 = 336
RATIO AREA/VOLUME = 320/336 . Simplify by dividing numerator and denominator by 16. Final result: AREA/VOLUME = 20/21
Answer:
Original price of ticket = $12.5
Step-by-step explanation:
Given:
8% amount = $1
