Since the hotdog is $2.99 with 7% tax increased by hotdog then
$2.99+0.07(2.99)
$2.99+$0.21
=$3.2
Answer:
0,-14
Step-by-step explanation:
5(x+7)²=245
divide both sides by 5
(x+7)²=49
Taking the square root of both sides
x+7=±7
Either x+7=7
subtract 7 from both sides
x+7-7=7-7
x=0
or
x+7=-7
subtract 7 from both sides
x+7-7=-7-7
x=-14
ANSWER
A. 22 in
EXPLANATION
The volume of a cone is calculated using the formula:
It was given that: the volume is 2,279.64 in³
The height of the cylinder is also given as: h=18 in.
We substitute, the given values into the formula to get:
We take positive square root to get;
Therefore the diameter is 2(11) which is equal to 22 inches.
Answer:
1/3
Step-by-step explanation:
To change from one base to another, we use the formula
Logb x = Loga x/Loga b
log1/9 (3^(1/3) /3)
log3 ((3^(1/3) /3))
-------------------------
log3 (1/9)
Log a /b = log a - log b
and 1/9 = 3^-2
log3 ((3^(1/3) ) - log3 (3)
-------------------------
log3 (3^-2)
log a^b = blog a
1/3 log3 (3 ) - log3 (3)
-------------------------
-2log3 (3)
We know log3 (3) =1
1/3 (1) - 1
-------------------------
-2 (1)
1/3 - 1
-------------------------
-2
-2/3
------
-2
Copy dot flip
-2/3 * -1/2
1/3
