Answer:
of the lasagna is left
<u>Step-by-step explanation:</u>
Given:
Amount of lasagna Rico eats = 1/9
Amount of lasagna His friend eats = 1/18
To Find:
The amount lasagna is left =?
Solution:
Total lasagna ate by both Rico and his friend = Amount of lasagna Rico eats + Amount of lasagna His friend eats
Total lasagna ate by both Rico and his friend = 
Total lasagna ate by both Rico and his friend = 
Total lasagna ate by both Rico and his friend = 
Total lasagna ate by both Rico and his friend = 
The amount lasagna is left = 1 - Total lasagna ate by both Rico and his friend.
The amount lasagna is left = 
The amount lasagna is left =
The amount lasagna is left =
Answer:
58 square feet
Step-by-step explanation:
The room is already broken down into two smaller rectangles.
The smaller of the two measures 4 ft by 2 ft. 
, so substitute 4 for 
and 2 for 
.
(smaller rectangle) 
, or 
.
(smaller rectangle) 
The larger measures 10 ft by 5 ft, so using the same method, multiply times .
(larger rectangle) 
, or 
.
(larger rectangle) 
Add the two rectangles' areas together to find the total area of the room.
8 + 50 = 58
Answer:
3√3+4
Step-by-step explanation:
Given the vectors u = <√3, -1> and v = <3, -4>
u · v = <√3, -1> *<3, -4>
u · v = 3√3 + (-1*-4)
u · v = 3√3+(4)
u · v = 3√3+4
Hence the dot product is 3√3+4
AB ≈ ED ( corresponding sides )
∠A ≈ ∠D ( corresponding angles )
∠C ≈ ∠F ( corresponding angles )
The perimeter is 16 inches
4.5+5.5+6=16
