Answer:
681 square inches
Step-by-step explanation:
The surface area of a rectangular prism of dimensions L, W, and H is given by ...
A = 2(LW +H(L+W))
The surface area of the given box is ...
A = 2(12·3 +18.25(12 +3)) = 2(36 +273.75) = 619.5 . . . square inches
The amount of wrapping paper required is 10% more than this value, so is ...
paper required = (1 +.10)(619.5) = 681.45 ≈ 681 . . . square inches
Answer:
36
Step-by-step explanation:
Given that Kelsay opened a bag of marbles.
The bag included 4 colours of marbles of equal numbers.
The four colours are red, yellow, green and blue.
To find the no of marbles of each colour in the bag:
Total number of marbles = 144
Total colours = 4
Hence divide total number by no of colours to get the answre
No of each colour marbles = 144/4 = 36
Answer:
One piece of pizza = $2.5
One candy bar = $1
Step-by-step explanation:
Call 1 pizza a, 1 candy bar b. We have:
2a + 3b = $8
=> 3(2a+3b) = 3. $8
= 6a + 9b = $24
and
6a + 5b = $20
=> (6a + 9b) - (6a + 5b) = 9b - 5b = 4b = $24 - $20 = $4
=> b = $1
=> 2a + $3 = $8
=> 2a = $5
=> a = $2.5
So one piece of pizza = $2.5, one candy bar = $1
Answer:
2300
