36 squared + 12 squared = AD squared
1296 + 144 = AD squared
square root of 1440 = AD
37.95
My first impulse is to say you don't provide enough info with which to solve this problem. We need to know how many inches in the model correspond to 1 foot in the actual plane (that is, the scale factor). What is the scale factor here?
Step-by-step explanation:
let w be the cost of a bottle of water and p be the cost of a bag of pretzels
"2 bottles of water and 3 bags of pretzels is $7.05" can be written as
2w + 3p = 7.05 ------------- eq.1
"The cost of a bag of pretzels is $1.35" can be written as
p = 1.35 ------------- eq 2
Together, eq 1 and eq 2 make up your system of equations
To solve, take eq 2 and substitute this value int eq 1
2w + 3 (1.35) = 7.05
2w + 4.05 = 7.05
2w = 7.05 - 4.05
2w = 3
w = 1.5
Hence the cost of a bottle of water is $1.50
First let's find the number of ham slices.
90-63 = 27
Then divide it by the total amount to get your percent.
27/90 = 3/10 = 30%
It is 30% ham. Hope this helps!
