Answer:
438.86
Step-by-step explanation:
1. 457 x 0.99 = 452.43 - Decreased by 1%
2. We need to decrease 452.43 again but this time by 3% - 452.43 x 0.97
3. This gives us an answer of 438.8571
4. Finally we need to round this to 2DP, the 7 (438.8571) rounds up so the number to the left increases. This leaves an answer of 438.86
Hope this helps :D
Answer:
1/14
Step-by-step explanation:
Assuming you mean that there are 2 red, 2 green, and 4 blue marbles, there are a total of 8 marbles.
On the first draw, the probability the marble is red is 2/8.
On the second draw, there's one less marble, so the probability of selecting a green marble is 2/7.
The total probability is:
2/8 × 2/7 = 1/14
Answer:

Step-by-step explanation:
Calculate the area of the two triangles first: 6 * 16 = 96
Then the rectangle: 10 * 16 = 160
160 + 96 = 256
B=c-5
c+b=185
so, c+(c-5)=185
2c=190
c=95
b=90
As simple as that.
Step 1: Add together the known angles.
Step 2: Subtract the sum from 180°.
