Answer:going down d,c,e,a
Step-by-step explanation:
<u>Area of triangle = (1/2) × Base × Height</u>
Area of bigger triangle = (1/2) × 15 cm × 10 cm
Area of bigger triangle = (1/2) × 150 sq. cm
Area of bigger triangle = 75 sq. cm
Similarly,
Area of smaller triangle = (1/2) × 12 cm × 5 cm
Area of smaller triangle = (1/2) × 60 sq. cm
Area of smaller triangle = 30 sq. cm
Area of shaded region = Area of bigger triangle - Area of smaller triangle
Area of shaded region = 75 sq. cm - 30 sq. cm
Area of shaded region = 45 sq. cm
<u>Answer</u><u> </u><u>:</u>
Area of shaded region in sq. cm = 45
Answer:
Vol of prism 1 is 650in^3 I believe and the SA of prism 2 is 260.
Step-by-step explanation:
4/10=.40
1625x.40=650
10/4=2.5
104x2.5=260
Answer:
1496.52 Pa, 14.76 atm
Step-by-step explanation:
This question can be solved using ideal gas law
according to which
pv = nrt
where p is the pressure of gas
v is volume of gas
n is amount gas in moles
R is ideal gas constant whose value is 8.314 J/mol
T is absolute temperature of gas on Kelvin scale
______________________________
given
v = 5 liter
n = 3
T = 300 kelvin
R = 8.314 J/mol
Let the pressure be p
Substituting the above value in ideal gas law equation we have
p*5 = 3*8.314*300
p = 7482.6/5 = 1496.52 Pa
This pressure is in pascal while option is in atm
we know 1 Pascal is equal to 0.0000098692 atm
we know that 1 Atm = 101325 Pa
thus, 1496.52 is equal to 0.0000098692*1496.52 atm
1496.52 is equal to 14.76 atm
