Mason, a hardwood flooring installer, needs to calculate the amount of hardwood flooring needed to cover a floor that's 33⁄4 yar
Aleksandr-060686 [28]

Answer:

20 5/8 yd^2

Step-by-step explanation:

width = 3 3/4 yd

length = 5 1/2 yd

First change both measurements to fractions.

3 3/4 = 3 + 3/4 = 12/4 + 3/4 = 15/4

5 1/2 = 5 + 1/2 = 10/2 + 1/2 = 11/2

area = length * width

area = 15/4 yd * 11/2 yd

area = (15 * 11)/(4 * 2) yd^2

area = 165/8 yd^2

165/8 = 20 remainder 5

area = 20 5/8 yd^2

Grandma bakes the world's best and favorite cookies. If grandma's cookies have a half life of 2 hours and she bakes 3 dozen cook
Alchen [17]

Answer:

The time that pass until only two cookies left is 1.89 hour

Step-by-step explanation:

Given as :

The number of cookies bakes in 2 hours = 3 dozen

∵ 1 dozen = 12 piece

So, In 3 dozen = 12 × 3 = 36 cookies

The Time required to bake 36 cookies = 2 hours

Now, Let The time required to bake 2 cookies = x hour

So, According to question

∵ The time required to bake 36 cookies = 2 hours

So, the time required to bake 1 cookies = \frac{2}{36} = \frac{1}{18} hour

∴The time required to bake 34 cookies =  \frac{1}{18} × 34

I.e The time required to bake 34 cookies = \frac{34}{18} hour = 1.89 hour

Or, the time taken is 1.89 hours

Hence The time that pass until only two cookies left is 1.89 hour Answer
