8 foot roll I think because 3 yards in a foot 3.42 divided by 1 is 3.42 and 3.60 divided by 8 is 0.45
Answer:
5 ± 2i√5
from the quadratic equation
The answer is: [D]: 0.211 .
____________________________________________________________
Explanation:
________________________
Given: 2(7)^(3x+1) = 48<span>; Solve for "x" (using "ln");
______________________________________________
First, divide EACH side of the equation by: "2" ;
____________________________________________
</span>→ [<span>2(7)^(3x+1)] / 2 = 48 / 2 ;
_____________________________________
to get: </span> → 7^(3x+1) = 24 ;
____________________________
→ Now, take the "ln" of EACH side of the equation:
____________________________________________
→ ln [7^(3x+1)] = ln 24 ;
→ (3x+1) ln 7 = ln 24 ;
→ Divide EACH side of the equation by "ln 7" ;
→ [(3x+1) (ln 7)] / ln 7 = (ln 24 / ln 7) ;
→ 3x + 1 = (ln 24 /ln 7)
_____________________________
(Using calculator, "(ln 24 / ln 7)" equals: "1.63319659538");
___________________________________________
→ 3x + 1 = 1.63319659538 ;
→ Subtract "1" from EACH side of the equation;
→ 3x + 1 − 1 = 1.63319659538 − 1 ;
→ 3x = 0.63319659538 ;
→ Now, divide EACH side of the equation by "3"; to isolate "x" on one side of the equation; and to solve for "x" ;
_______________________________________________
→ 3x / 3 = 0.63319659538 / 3 ; (using calculator);
____________________________
to get:
____________________________________________
→ x = 0.2110655317933333 ; which is:

Here, we area provided a cone with:
- Radius = 48m
- Height = 68 m
We have to find the volume of the cone in feet³, and we are given that 1m = 3.2808ft
<h3><u>Ⳙ⳽ⲓⲛⳋ ⳨ⲟⲅⲙⳙ</u><u>ⳑɑ</u><u>:</u></h3>
