80 times could Kaitlyn expect to pull out a blue chip.
<u>Step-by-step explanation</u>:
- The total number of chips in the bag = 7 white+5 red+ 8 blue = 20 chips.
- Probability (blue chip) = number of blue chips / total chips
P(blue) = 8/20
She does this 200 times.
P(blue) for 200 times = (8/20)
200 = 80.
Answer:
- 20 taffy bags and 15 caramel candy bags
Step-by-step explanation:
<u>Given:</u>
- t = the number of taffy bags
- c = the number of caramel bags
- Number of taffy's are 5 more than caramel bags
- Taffy bags weigh 8 ounces and caramel bags weigh 16 ounces
- Total weight is 400 ounces
<u>Equations:</u>
- t = c + 5 (the difference in number of bags)
- 8t + 16c = 400 (the weight of the bags)
<u>Simplify the second equation by dividing all terms by 8:</u>
<u>Substitute t and solve for c:</u>
- c + 5 + 2c = 50
- 3c = 50 - 5
- 3c = 45
- c = 45/3
- c = 15
<u>Find the value of t:</u>
<u>Answer:</u>
- 20 taffy bags and 15 caramel candy bags
47+ 30 is 77 so def is 77 and 103 is deg. and
Answer:
Area of circle A =113.14 mm²
Area of circle b = 314.29 mm²
Area of circle C = 452.57 mm²
Area of circle A = 254.57 mm²
2.25 times
Step-by-step explanation:
Area of a circle = nr²
where n = 22/7
r = radius
Circle A's radius = 6mm
Circle B's radius = 6mm + 4mm = 10mm
Circle C's radius = 10mm + 2mm = 12mm
Circle D's radius = 12mm - 3mm = 9mm
Area of circle A = (22/7) x 6² = 113.14 mm²
Area of circle b = (22/7) x 10² = 314.29 mm²
Area of circle C = (22/7) x 12² = 452.57 mm²
Area of circle A = (22/7) x 9² = 254.57 mm²
Number of times the area of circle D is greater than that circle A = Area of circle D / Area of circle A
254.57 mm² / 113.14 mm² = 2.25 times
