The answer is 21 because you do PEMDAS first. (8-8) is 0. And 0+21 is 21
Answer: The answer would be C
Step-by-step explanation:
37 + 5 = 42
Each teacher needs 8 and there are 5 teachers
5 x 8 = 40
So each teacher can have 8 apples and there will be two left over
Answer:
Total surface area : 733
The shape of the base is a rectangle with sides 11 in. and 12 in.
Step-by-step explanation:
The shape of the base is a rectangle with sides 11 in. and 12 in.
The surface area is the sum of the areas of the 5 sides.
Area of the base = 11*12 = 132
Area of the two triangles = (11*16)/2 = 88
Area of the back rectangle = 192
The theorem of Pitagora to find the oblique side: square root of (11*11 + 16*16)= 19.42 in.
So the area of the oblique face: 19.42* 12 = 233 (almost :) )
So total surface area: 132 + 88*2+192+233= 733 square in
