Answer:
C and D
Step-by-step explanation:
The length of the sides will be irrational if it is not a whole number. The tile installer has a square shape, so the formula for area is
area= 
Since we need to find if the side has the whole number, we can make the function to solve for side
side=
Then the side for each tile installer will be:
A= 
= 5 inch
B= 
= 6 inch
C= 
= 6.78 inch
D= 
= 7.74 inch
Both C and D have irrational sides
Answer:the total value of the account after 3 years is $7266
Step-by-step explanation:
Initial amount that Ryan invested into account is $500 This means that the principal is P, so
P = 7000
It was compounded annually. This means that it was compounded once in a year. So
n = 1
The rate at which the principal was compounded is 1.25%. So
r = 1.25/100 = 0.0125
It was compounded for 3 years. So
n = =3
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 7000 (1+0.0125/1)^1×3
A = 7000(1.0125 )^3= $7266
Answer:
the first option
Step-by-step explanation:
equilateral triangles are also equiangular which means each of the three angles is 60°
but you can have an acute triangle with angle measures that are all acute (for example, 59°, 85°, and 36°) that is not equilateral
