5. Kathy plans to purchase a car that
depreciates (loses value) at a rate of 14% per
year. The initial cost of the car is $21,000.
How much will the car be worth
in 6 years?
Answers
Answer:
At the end of the 1st year you have 21,000-0.14(21000)
= (1-0.14)21000 = 0.86(21,000)
So after three years you have 21000(0.86)(0.86)(0.86)
= 21000(0.86)^3
Answer:
3360
Step-by-step explanation:
Find 14% of 21,000 then multiply by six which gives you 17,640. Then you subtract 21,000-17640. that is your answer.

10) At a local department store, slacks have been reduced to $27. This price is at 69.2% of the original price for slacks. Given this, what was the original price of the slacks? Round your answer to the nearest whole number if necessary.
Answers
Answer:
9): 64.7
10): 39$
Step-by-step explanation:
Answer:
64.7% and $39
Step-by-step explanation:
Question 9:
This means that the baseball team won 22/34 of their games through their entire season. In order to find the percentages of game they won, you divide 22 by 34, which comes out to 0.64705..., which becomes 64.705%. Rounding this to the nearest tenth, this percentage becomes 64.7%. Therefore, the percentage of games their baseball team is 64.7%.
Question 10:
We can represent this problem as the proportion:
[tex]\frac{27}{69.2} =\frac{x}{100}[/tex]
with x being the original price of the slacks.
We cross multiply to solve this equation. 27 times 100 is 2700. Next, we divide 2700 by 69.2, which comes out to 39.017341. Rounding this to the nearest whole number, this value comes out to 39. Therefore, the original price of these slacks is $39.
If a seed is planted, it has a 95% chance of growing into a healthy plant.
If 7 seeds are planted, what is the probability that exactly 3 do grow? Round to 4 decimal places.
Answers
If 7 seeds are planted, the probability that exactly 3 do grow is;
P(X = 3) = 0.0002
This is a binomial probability distribution problem where;
P(X = x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾
We are given;
p = 95% = 0.95
q = 1 - p
q = 1 - 0.95
q = 0.05
Thus If 7 seeds are planted, the probability that exactly 3 do grow is;
P(X = 3) = ⁷C₃ × 0.95³ × 0.05⁽⁷ ⁻ ³⁾
P(X = 3) = 35 × 0.857375 × 0.00000625
P(X = 3) = 0.000187
To four decimal places gives;
P(X = 3) = 0.0002

Complete the table for the given rule.
Rule: y is 1 less than 2 times x

According to the rule, the table is:
x|y
2|3
3|5

The translation of the rule to a math expression is:
[tex]y = 2x - 1[/tex]
Then, for x = 2:
[tex]y = 2(2) - 1 = 4 - 1 = 3[/tex]
For x = 3:
[tex]y = 2(3) - 1 = 6 - 1 = 5[/tex]
For x = 4:
[tex]y = 2(4) - 1 = 8 - 1 = 7[/tex]

The scale of a map says that 4 cm represents 5 km. a. what distance on the map (in centimetres) represents an actual distance of 4 kilometres? b. What is the actual number of kilometres that is represented by 5 centimetres on the map?
Answers
Answer:
a. 3 cm
b. 6 km
Step-by-step explanation:
to be completely honest, I just shoot my answer based on the pattern.
if you notice that when the scale is 4 cm, the actual distance is 5 km. When the distance is 4 km, the scale should probably be 3 cm. It's the same with the 5 cm scale, then the distance should be 6 km
Step-by-step explanation:
Use ratios to solve it
a)
4 cm → 5 kmx cm → 4 kmx = 4*4/5 = 3.2 cm
b)
4 cm → 5 km5 cm → x kmx = 5*5/4 = 6.25 km
