Answer:
C. 26
Step-by-step explanation:
Let’s suppose that the first question is worth ‘’x’’ amount of points. Then the second question will be worth x+4, the third question x+8, the fourth question x+12, the fifth x+ 16, the sixth x+20, the seventh x+24, the eighth x+ 28, the ninth x+ 32, and the last one x + 36.
The sum of the points of all these questions is equal to 10x + 180. Since the quiz has a total of 360 points, then
10x + 180 = 360.
Solving for x we get:
X = 18.
This means that the first question is worth 18 points, the second one 22 points (18 +4), the third one 26 points(18+4+4), and so on.
12.57 * 4.11 = 51.66
1257 *remove the decimal and treat the numbers as whole numbers.
<u> x 411</u>
1257 * 1 x 1257
12570 *10 x 1257
2800 *400 x 7
20000 *400 x 50
80000 *400 x 200
+ <u>400000 </u> *400 x 1000
516627
516627 is the product of 12.57 and 4.11 without their decimal points.
516627. the decimal point must be moved 4 places because the total count of numbers after the decimal is 4.
from 516627 to 51.6627 ; round to the nearest hundredth 51.66
There are 5 + 7 = 12 triangles or hexagons. So the probability is 12/15 = 4/5. As a percent, it would be 80%.

Answer:
0.4
Step-by-step explanation:
Probability = Favourable Outcomes / Total Outcomes
Probability (Blue socks drawn out) = Blue Socks pairs / Total Socks pairs
6 / ( 5 + 6 + 3 + 1 )
= 6 / 15
= 0.4
