Answer:

$106.50

Step-by-step explanation:

Take 100 and multiply it by 6.5%. This will give us 6.5, the amount of tax to pay. Then add 100 to 6.5 giving you the total of $106.50.

A positive integer is 47 more than 9 times another. Their product is 1860. Find the two integers.
svlad2 [7]
X = 47 + 9y
xy = 1860

y(47 + 9y) = 1860
47y + 9y² = 1860
9y² + 47y - 1860 = 0

> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b+/- √(b²-4ac)]/(2a)
> only integer solution is x = 12

12y = 1860
y = 155

integers are 12 and 155

Hey user!!!

given the radius of the cylindrical mold is 2 inches and height is 3 inches.

volume of the cylindrical mold = πr²h

= 3.14 × 2 × 2 × 3

= 37.68 in³


radius of the spherical mold is given = 2 inches

volume of the spherical mold = 4/3πr³

= 4/3 × 3.14 × 2 × 2 × 2

= 100.48/3 in³


difference between the amount of wax needed = 37.68/1 - 100.48/3

= ( 113.04 - 100.48 ) / 3

= 12.56/3

= 4.186...

so approximately 4.19 in³

hence, correct option is 4.19 in³


cheers!!!
