Answer:
165 mL
Step-by-step explanation:
Density is mass divided by volume:
D = M / V
Solving for volume:
V = M / D
The density is given in g/mL. So first let's convert the mass from kg to g:
2.25 kg × (1000 g / kg) = 2250 g
Plugging in values:
V = (2250 g) / (13.6 g/mL)
V = 165.4 mL
Rounded to 3 significant figures, the volume is 165 mL.
Answer:
9000rs.
Step-by-step explanation:
No. Of math book teacher bought =45
No of english books teacher bought =45
Cost of English books -105rs.
Cost of math books -95rs
Teacher paid-45 x 105+42×95
-45x (105 + 95)
-200
-9000 rs.
first you would multiply 25 x 3, which is 75 and then multiply 60 x 2 which is 120, then add 120 and 75 together, making the answer 195
Answer:
x = 10
Step-by-step explanation:
108 = (5x + 47) + (2x + 63)
5x + 47 + 2x + 63 = 180
Simplify
7x + 110 = 180
Move all terms not containing x to the right side of the equation.
7x = 70
Divide
x = 10
