Answer:
13/12
Step-by-step explanation:
b=7/4-2/3
b=(21-8)/12
b=13/12
The answer is the first option, 3/1
#13:
s² = 144
√(s²) = √144
|s| = 12
s = -12 OR s = 12
--------------------
#15 (not sure what letter you used so I went with 'g')
(g-6)² = 25
√[(g-6)²] = √25
|g-6| = 5
g - 6 = -5 OR g - 6 = 5
g = 1 OR g = 11
Answer:
1350 km yw!
Step-by-step explanation:
The hypotenuse of the triangular surface will be given by the Pythagorean theorem;
c^2=a^2+b^2
c^2=5^2+12^2
c^2=25+144
c^2=169
c=13m
the LA is given by:
AL=(a+b+c)h
AL=(13+12+5)5
AL=30(5)
AL=150 m^2
SA:
SA=2(1/2bh)+(l*w)+(l*w)+(l*w)
SA=(5*12)+(5*5)+(5*13)+(5*12)
SA=60+25+65+60
SA=210 m^2
Volume:
V=(base area)*height
V=(1/2*5*12)*5
V=150 m^2
