Answer = 36.0 mph
As per the question,
Actual speed of the car = 40 mph.
Speedometer has a percent error of 10%.
The error can be negative as well as positive.
If the error is negative, it means speedometer is showing less speed than actual speed= - 10%
10 % of 40 = 4
speed shown by speedometer = 40 - (10% of 40) = 36 mph
If the error is positive, it means speedometer is showing more speed than actual speed = +10%
speed shown by speedometer = 40 + ( 10% of 40) = 44 mph
as per the given options, correct option is 36.0 mph
Answer:
Table 3 and Table 5
Step-by-step explanation:
y = 3/5 x
The slope is 3/5
3/5 = .6
We want a slope that is lower
We want to find the slope for each table
Slope is found by
m = (y2-y1)/(x2-x1)
Table 1
= (12-4)/(9-3) = 8/6 = 4/3 =1.33
Table 2
= (12-4)/(15-5) = 8/10 = 4/5=.8
Table 3
= (54-18)/(93-31) = 36/62=18/31=.58
Table 4
= (33-11)/(54-18) = 22/36 = 11/12=.92
Table 5
= (21-7)/(36-12) =14/24 = 7/12 =.58
Answer:
17.74
Step-by-step explanation:
The fraction is easily converted to one with a denominator of 100 (a power of 10):
Then the number of interest is ...
17 37/50 = 17 74/100 = 17.74
Answer:
78 255.20
Step-by-step explanation:
The formula for compound interest is:
A = P(1 + r)ⁿ
Data:
P = 58 000
APR = 3.75 %
t = 8 yr
Calculations:
n = 8 × 12 = 96
r = 0.0375/12 = 0.003 125
A = 58 000(1+ 0.003 125)⁹⁶
= 58 000 × 1.003 125⁹⁶
= 58 000 × 1.349 2275
= 78 255.20
Your balance will be 78 255.20.
