Step-by-step explanation:
1. simple interest
I= p × r × t
I = 1050 × 4.5 × 2
I = $9450
2. principal
p = I/(rt)
p= 22.50/ (3× 3)
p = 22.50/9
p = $2.5
3. simple interest
I= p × r × t
I = 500 × 5 × 3
I = $7500
4. time
first convert r to decimal
r= r/100, r= 3.5 / 100
r= 0.035
t = i/(pr)
t = 43.75/ (2500× 0.035)
t = 43.75/ 87.5
t = 0.5 year or 6 months
Answer:
4. No
5. No
6. No
7. No
8. No
9a. 2 : 3 = 8 : 12 Extremes: 2, 12. Means: 3, 8
9b. 90 : 36 = 135 : 54 Extremes: 90, 54. Means: 36, 135
Step-by-step explanation:
4. 12 : 25 and 6 : 13 are NOT equal. NO.
5. 64 : 120 = 8 : 15 and 60 : 100 = 3 : 5. NOT equal. NO
6. 37 : 115 and 296 : 966 = 148 : 483. NOT equal. NO
7. 300 : 200 = 3 : 2 and 6 : 5 are NOT equal. NO.
8. 8 : 10 = 4 : 5 and 11 : 14 are NOT equal. NO.
9a. 2 : 3 = 8 : 12 Extremes: 2, 12. Means: 3, 8
9b. 90 : 36 = 135 : 54 Extremes: 90, 54. Means: 36, 1135

Answer:
36.4mi
Step-by-step explanation:
The boat sailed two legs of a right-angled triangle.
The distance from the starting point is the hypotenuse of the triangle.
d = √(35² + 10²)
= √(1225 + 100)
= √1325
= 36.4 mi
R = 16 according to the problem, so the total amount of income will be:
$20*16 + $15*(40 - 16)
= $320 + <span>$15*(24)
= </span>$320 + <span>$360
= $680
that is the income, but the expenses are $275 so the total revenue is the subtraction of those two
total revenue = $680 - $275
= $405</span>
