Answer:
5 km
Step-by-step explanation:
From. The question, the triangle formed us a right angled triangle,
h km directly from starting point is the hypotenus, h :
Hypotenus = sqrt(opposite² + Adjacent²)
h = sqrt(4² + 3²)
h = sqrt(16 + 9)
h = sqrt(25)
h = 5 km
Answer:
C. 54
Step-by-step explanation:
36/60=.6
90*.6=54
Answer:
Square
Step-by-step explanation:
It has four coordinates which means four vertices which is four sides. Can also be a rectangle or parallelogram.
.
The first thing you need to do is convert the yards into feet. In one yard there are three feet. So 2*3=6 now you can do the triangle area equation. 6*4.25=25.5 then divide by two. 25.5/2=12.75So the area of the triangle is 12.75 ft^2Hope this helps
Answer:
31 children and 290 adults
Step-by-step explanation:
Let a = number of adults and c = number of children.
a + c = 321
2a + 1.75c = 634.25
Multiply both sides of the the first equation by -2 and add it to the second equation.
-2a - 2c = -642
(+) 2a + 1.75c = 634.25
--------------------------------------
-0.25c = -7.75
Divide both sides by -0.25
c = 31
Use the first equation to find a.
a + c = 321
Substitute 31 for c.
a + 31 = 321
Subtract 31 from both sides.
a = 290
Answer: 31 children and 290 adults
