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
Answer:
C
Step-by-step explanation:
six plus four is ten
six minus four is 2
''m' represents radius of the circle.
Substitute m(t) into Area function.
Now you have Area as function of time.
part B) sub t= 3 to find Area after 3 minutes.
The perimeter is 90, and to calculate the perimeter of rectangle, the equation is ( Length + width ) x2,
so in this case, it should be (6x + 2x) x 2 = 90,
therefore x = 5.625
and therefore the longest side is 5.623 x 6, so the answer should be 33.75
42 dollars/7 minutes
÷ by 7 on both
