<h3>Ratio of length of red ribbon to blue ribbon is 9 : 8</h3>
<em><u>Solution:</u></em>
Given that,
Robin is making bows to sell at her mother's yard sale
From given,
![\text{Length of red ribbon } = \frac{3}{4}\ foot\\\\\text{Length of blue ribbon } = \frac{2}{3}\ foot](https://tex.z-dn.net/?f=%5Ctext%7BLength%20of%20red%20ribbon%20%7D%20%3D%20%5Cfrac%7B3%7D%7B4%7D%5C%20foot%5C%5C%5C%5C%5Ctext%7BLength%20of%20blue%20ribbon%20%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5C%20foot)
<em><u>What is the ratio of the length of red ribbon to blue ribbon?</u></em>
![Red : blue = \frac{3}{4} : \frac{2}{3}\\\\Red : blue = \frac{3 \times 3}{4 \times 3} : \frac{2 \times 4}{3 \times 4}\\\\Red : blue = \frac{9}{12} : \frac{8}{12}\\\\Red : blue = 9 : 8](https://tex.z-dn.net/?f=Red%20%3A%20blue%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%3A%20%5Cfrac%7B2%7D%7B3%7D%5C%5C%5C%5CRed%20%3A%20blue%20%3D%20%5Cfrac%7B3%20%5Ctimes%203%7D%7B4%20%5Ctimes%203%7D%20%3A%20%20%5Cfrac%7B2%20%5Ctimes%204%7D%7B3%20%5Ctimes%204%7D%5C%5C%5C%5CRed%20%3A%20blue%20%3D%20%5Cfrac%7B9%7D%7B12%7D%20%3A%20%5Cfrac%7B8%7D%7B12%7D%5C%5C%5C%5CRed%20%3A%20blue%20%3D%209%20%3A%208)
Thus ratio of length of red ribbon to blue ribbon is 9 : 8
Answer:
Radius = 2.8
Step-by-step explanation:
V = 1⁄3 πr² × h
50 = 1⁄3 πr² × 6
50 = 1⁄3 × 22⁄7 × r² × 6
50 = 22⁄21 × r² × 6
50 = 22⁄21 × 6 × r²
50 = 6.286 × r²
50 = 6.286r²
50/6.286 = 6.286r²/6.286
r² = 7.954
r = √7.954
r = 2.820

Answer:
radius r = 2.82094792 m
height h = 6 m
slant height s = 6.63006389 m
volume V = 50 m3
lateral surface area L = 58.7574113 m2
base surface area B = 25 m2
total surface area A = 83.7574113 m2

Answer:
![Total\ Cost = \$973.75](https://tex.z-dn.net/?f=Total%5C%20Cost%20%3D%20%5C%24973.75)
Step-by-step explanation:
Given (Missing part of question)
T-shirts = $7.50
Shorts = $9.00
Windbreakers = $12.25
Required
Determine the total cost
Total Cost is calculated as follows;
![Total\ Cost = Costs\ of\ T-Shirts + Costs\ of\ Shorts + Costs\ of\ Windbreakers](https://tex.z-dn.net/?f=Total%5C%20Cost%20%3D%20Costs%5C%20of%5C%20T-Shirts%20%2B%20Costs%5C%20of%5C%20Shorts%20%2B%20Costs%5C%20of%5C%20Windbreakers)
![Total\ Cost = 35 * \$7.5 + 45 * \$9.00 + 25 * \$12.25](https://tex.z-dn.net/?f=Total%5C%20Cost%20%3D%2035%20%2A%20%5C%247.5%20%2B%2045%20%2A%20%5C%249.00%20%2B%2025%20%2A%20%5C%2412.25)
![Total\ Cost = \$262.5 + \$405.00 + \$306.25](https://tex.z-dn.net/?f=Total%5C%20Cost%20%3D%20%5C%24262.5%20%2B%20%5C%24405.00%20%2B%20%5C%24306.25)
![Total\ Cost = \$973.75](https://tex.z-dn.net/?f=Total%5C%20Cost%20%3D%20%5C%24973.75)
Area of the bigger rectangle =(18×8)cm
2
=144cm
2
Area of the smaller rectangle =((30−18)×(8−6))=(12×6)cm
2
=72cm
2
∴ Total area = area of smaller rectangle + area of bigger rectangle =(72+144)cm
2
=216cm
