Answer:
9 White marbles are present in the bag.
Step-by-step explanation:
Let the number of White marbles present in the bag be X and number of Yellow marbles present be Y .
Then according to the question ,
X + Y = 16 -(1) (As total marbles are 16)
Also,
X = 2Y - 5 -(2)
From Equation 1 , X = 16 - Y , Comparing with Equation 2 , we get,
16 - Y = 2Y - 5
3Y = 21.
Y = 7.
So, X = 16 - Y = 16 - 7 = 9.
Thus, 9 White marbles are present in the bag.
Answer:
41.472 m²
8.449m²
Step-by-step explanation:
c) scale facot is 7.2/5 = 1.44
the square scale factor is 1.44^2 = 2.0736
times 20 by this to get the area
2.0737x 20 = 41.472 m²
d) 2.8/6 = SF = 0.467
0.2178 x 38.8 = 8.449m²
