The solution is in the following image
The wood before starting =12 feet
Left wood=6 feet
Wood used till now=12-6=6 feet
Picture frame built till now= 6/(3/4)
=8 pieces
Therefore, till now 8 pieces have been made.
Salesperson will make 6% of 1800
=(6/100)*1800
=108
Salesperson will make $108 in $1800 sales
Area of rectangle= L*b
here,
L=12.4 cm
b= 8.8 cm
A= L*b
= 12.4 * 8.8 = 109.12 cm^2
Volume of rectangular prism=length * width * height
Given,
length=3/8cm
breadth=5/8cm
height=7/8cm
therefore volume=(3/8)*(5/8)*(7/8)
=105/512 cm3
Cost of 6 gallons =$15
Cost of 1 gallon =15/6
=$2.5
Cost of 7 gallons=$2.5 * 7
=$17.5
We can put the numbers in ascending order-
36, 38, 39, 39, 40, 47, 48, 51
Range=max-min
=51-36
=15
There are 6 outcomes 1,2,3,4,5,6
Total outcomes = 6
Outcomes when rolling a number is 4 or less = 1,2,3,4
Total outcome when rolling a number is 4 or less=4
Probability = required outcome/total outcome
=4/6
=2/3
Therefore probability = 2/3
The answer is in the image
It will provide an instant answer!
