The barrel holds 13.20 liters
No greater means equal or less. Because the problems asks about the highest score(maximum value), we are going to solve following equation:
(72+78+73+x)/ 4 = 74
(72+78+73+x)=74*4
223+x=296
x=296-223= 73
Answer is 73.
Answer:
longer side = √507 cm, shorter side = 13 cm
Step-by-step explanation:
sin60 = opposite side/26cm
opposite side = √507 cm
cos60 = adjacent side/ 26cm
adjacent side = 13 cm
longer side = √507 cm, shorter side = 13 cm
Answer:
a = 242 adult and c = 52 children
Step-by-step explanation:
Solving as a system of equations.
a = adult
c = children
The adult and the children equal 294 people
a + c = 294
adult cost is 2.25 per adult
Total amount of adult is 2.25a because the number of adult are not given.
children cost is 1.75 per children
Total amount children is 1.75c because the number of children are not given
Total receipts $635.50.
a + c = 294 <em>multiply by -1.75</em> -1.75a - 1.75c = - 514.50
2.25a + 1.75c = 635.50 <em>does not change </em>2.25a + 1.75c = 635.50
<em>Add these equations together</em>
-1.75a - 1.75c = - 514.50
<u><em> </em></u><u>2.25a + 1.75c = 635.50 </u>
<em> </em> .50a = 121.00
a = 121.00/.50a
a = 242 adult
a + c = 294
242 + c = 294
c = 294 - 242
c = 52 children
Check: $2.25(242) + $1.75( 52) = $635 .50
$544.50 + $91.00 = $635.50
$635.50 = $635.50
