Answer:
13.9%
Step-by-step explanation:
The value of car is modeled as:
Here we can see that, each year Nathan has considered 0.861 of the previous year value or we can say that Nathan has considered 86.1% of the previous year value. So,
We subtract the percentage value considered from 100 to find out the percentage decrease in the value of the car.
The value of new car is decreasing by 13.9% each year.
They model various situations where there is an increasing curve. An example is if you throw a baseball and it curves back down as gravity has more and more of a affect on it. This would be a different equation than if you threw a basketball as the basketball wouldn't go as high but would have about the same downwards acceleration due to gravity.
Answer:
12
Step-by-step explanation:
Side 9 applies to side 18
Side 7 applies to side 14
the factor is multiply by two
So 6 times 2 is 12
Answer:
Cost of shrubs = 23
Cost of tree = 47
Step-by-step explanation:
Let
Cost of shrubs = x
Cost of tree = y
13x + 4y = 487 (1)
6x + 2y = 232 (2)
Multiply (2) by 2
12x + 4y = 464 (3)
13x + 4y = 487 (1)
Subtract (3) from (1)
13x - 12x = 487 - 464
x = 23
Substitute x = 23 into (2)
6x + 2y = 232 (2)
6(23) + 2y = 232
138 + 2y = 232
2y = 232 - 138
2y = 94
y = 94/2
= 47
y = 47
<em><u>0.9506</u></em>
Step-by-step explanation:
here's the easy explanation:
We have 2% and 3%.
Take them both away from 100 since we're decreasing!
<em>100 - 2 = 98</em>
<em>100 - 3 = 97</em>
Divide them both by 100.
<em>98 --> 0.98</em>
<em>97 --> 0.97</em>
Times them both together!
<em>0.98x0.97 = 0.9506</em>
