<u>Given</u>:
The given graph represents the cost of the Kayak's rental per hour.
The coordinates are (2,30) and (3,45)
We need to determine the unit rate of renting per hour.
<u>Unit rate of renting:</u>
The unit rate of renting can be determined using the formula,
Substituting the coordinates (2,30) and (3,45), we get;
Simplifying, we get;
Dividing, we get;
Thus, the unit rate for renting a Kayak is $15 per hour.
Answer:
Step-by-step explanation:
let : x The length and y the width you have this system :
xy =60....(1)
x = y+10...(2)
put the value for x in (1): (y+10)y =60
the quadratic equation is : y² +10y - 60 = 0
Δ =b² - 4ac a = 1 b= 10 c= - 60
Δ =10² - 4(1)(-60) = 324 =18²
y 1 = (-10-18)/2 negatif...... refused
y 2 = (-10+18)/2 =4
the width is 4
Answer:
1: 36.561
2: 45701.25
Step-by-step explanation:
31076.85/850 = 36.561
36.561*1250=45701.25
Answer:
$158.8
Step-by-step explanation:
There are 12 months in 1 year.
If in 1 year, it looses value of 10.3%, so in a month it will loose value of:
10.3%/12 = 0.8583% per month
So, to find the decreased value (in dollars) per month, we got to find 0.8583% of 18,500 dollars.
First, we need to convert percentage to decimal by dividing by 100. Then we multiply that to 18,500 to get our answer. So:
0.8583% = 0.8583/100 = 0.008583
Now,
0.008583 * $18,500 = $158.7855
Rounded to nearest tenth (1 decimal pae) = $158.8
