Answer:
Chantelle will pay $73 of interest for a loan of $3,500 with an APR of 4.25%.
Step-by-step explanation:
Since APR is defined as the anual percentage rate, the amount of interest that Chantelle will pay can be expressed as:
I=L*(1+APR/100%)^n-L
Where L is the amount of money borrewed and n the numbers of years. As Chantelle repay the loan in less than a year n is less than 1:
n = 6 months / 12 months = 0.5
Then replacing the calculated value of n, the ARP and the the borrowed money:
I=$3,500*(1+4.25%/100%)^0.5-$3,500
I=$3,500*(1+0.0425)^0.5-$3,500
I=$3,500*1.021-$3,500
I=$3,573-$3,500
I=$73

Answer:
Lengths of the sides (there are 3 sides in an equilateral triangle) of the base of prism is5.72cm each.
Step-by-step explanation:
As the base of triangular prism is equilateral:
∴ Area of base = (√ 3 / 4)× (side)²
According to question:
height of prism = height (side) of base
Volume of prism = 81 cm³,
∴ Volume of prism = Area of base x height
⇒ 81 cm³ = (√ 3 / 4)× (side)² × height ∵ side = height
⇒ 81 cm³ = (√ 3 / 4)× (side)³
⇒ 81 × (4/√3) cm³ = side³
⇒ ∛(81 × (4/√3) cm = side
⇒ side = 5.72cm
