Answer:
0.3276%
Step-by-step explanation:
-The percentage of error is the the percentage deviation from the real value.
-Given the real value is 427.4 m and the pedometer value is 426m, the % of error is calculated:

Hence, the percentage of error is 0.3276%
Answer:
right triangles
always
Step-by-step explanation:
Similar triangles are obtained by rise/run
Since the ratio for all triangles are the same, they have the same slope.

Answer:
To calculate compounded interest, use the compound interest formula.
A(t)=P(1+rn)n⋅t
Recognize the information given in the problem.
P=2560,r=0.035,n=1,t=4
Substitute the values into the appropriate position in the formula.
A(4)=2560(1+0.0351)1⋅4
Simplify by multiplying and dividing by 1.
A(4)=2560(1+0.035)4
Simplify using the order of operations.
A(4)=$2,937.66
The balance at the end of 4 years would be $2,937.66.
Step-by-step explanation:
Part A-For marigold plants X, a geometric sequence has a general form of:
X = Xo * (1 + r)^n
where r = -15% = -0.15 (negative since it is decreasing)
Xo = the initial amount of marigold plants = 150
X = 150 * (1 – 0.15)^n
X = 150 (0.85)^n
