if asking for hours to miles (as it looks like in this case, x to y) it would be 1/53
Answer:
Step-by-step explanation:
volume =1/3×base area×height
216=1/3× A×6
base area=216/2=108 in²
Answer:
1. Find < ACB
2. Use that triangles =180 to find <B = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41
Answer:
-53.754
Step-by-step explanation:
<u>step 1:</u>
9.03 + 19.87 = 28.9
<u>step 2:</u>
3.11 - 4.97 = -1.86
<u>step 3:</u>
28.9 x -1.86 = -53.754
Answer:the cost of one drink is $7
the cost of 1 bag of popcorn is $6.5
Step-by-step explanation:
Let x represent the cost of one drink.
Let y represent the cost of 1 bag of popcorn.
Aiden spends a total of $46.00 on 6 drinks and 1 bag of popcorn. This means that
6x + y = 46 - - - -- - - - - - -1
Jeremiah spends a total of $134.00 on 12 drinks and 8 bags of popcorn. This means that
12x + 8y = 134 - - - - - - - - 2
Multiplying equation 1 by 8 and equation 2 by 1, it becomes
48x + 8y = 368
12x + 8y = 134
Subtracting equation 2 from equation 1, it becomes
36x = 234
x = 234/36 = 6.5
Substituting x = 6.5 into equation 1, it becomes
6 × 6.5 + y = 46
39 + y = 46
y = 46 - 39 = 7
