Inequality: 21d+25≤115

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Step-by-step explanation:

Given,

Per day rent = $21.00

Per mile rent = $0.10

Miles to be driven by Jim = 250

Cost of 250 miles = 250*0.10 = $25

Amount Jim can spend = $115.00

Let,

d represent the number of days.

Per day rent*number of days + cost of 250 miles ≤ Total amount to spend

21d+25≤115

Subtracting 25 from both sides

21d+25-25\leq 115-25\\21d\leq 90

Dividing both sides by 21

\frac{21d}{21}\leq \frac{90}{21}\\d\leq 4.28

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

0.10d + 0.25q = 3.55
q = d + 3

0.10d + 0.25(d + 3) = 3.55
0.10d + 0.25d + 0.75 = 3.55
0.10d + 0.25d = 3.55 - 0.75
0.35d = 2.80
d = 2.80/0.35
d = 8.....8 dimes

q = d + 3
q = 8 + 3
q = 11 <=== 11 quarters

The ropes on either side of a swing are 1.9 m long. If a child swings through a arc length of 0.9 Determine the angle (in radian
Yuliya22 [10]

Answer:

theta = 9/19 radians or  approximately .4737 radians

Step-by-step explanation:

The formula for arc length is

S = r theta  

where theta is in radians.  Lets put in what we know.  The radius would be 1.9 since the ropes would be the radius.

.9 = 1.9 theta

Divide by 1.9 on each side.

.9/1.9 = theta

theta = 9/19 radians

or in decimal form it is approximately  .4737 radians
