Because thee dimensions of ΔRAH is twice as large as corresponding dimensions of ΔEAC,
|RA|=2|EA|=2*3.5=7
|AH|=2|AC|=2*6=12
So, we have that 2 corresponding sides are in proportion and angle between them =90⁰, so the angle between them are congruent,
we can use SAS to prove that these triangles are similar.
<u>Answer:</u> Parallel.
Two or more lines that lie in the same plane and never intersect. Parallel lines will always have the same slope. Skew lines are lines that are in different planes and never intersect. A transversal is a line that intersects two other lines.
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
