Assume that
a and b = the two legs of the right triangle.
c = the hypotenuse.
The area of the right triangle is 750 yd², therefore
(1/2)*a*b = 750
ab = 1500 (1)
The perimeter is 150yd, therefore
a + b + c = 150 (2)
Let the side fenced with wood be a, at $5/yd. Sides b and c are fenced with steel at $10/y. The total cost is $1200, therefore
5a + 10b + 10c = 1200
or
a + 2b + 2c = 240 (3)
From (2), obtain
c = 150 - a - b (4)
Substitute (4) into (3)
a + 2b + 2(150 - a - b) = 240
-a + 300 = 240
a = 60
From (1), obtain
60b = 1500
b = 25
From (4), obtain
c = 150 - 60 - 25 = 65
Answer:
A. The length of the leg fenced with wood is 60 yd.
B. The length of the leg fenced with steel is 25 yd.
Answer:
C) 25
Step-by-step explanation:
First, solve for the height (red dotted line) using the Pythagorean theorem 9²+b²=15²
81+b²=225
b²=225-81
b²=12
Then set up a ratio.
x/12=9/15
simplify
x/12=3/5
cross-multiply
3x=60
x=20
This gives us the base. Now we can solve for x using the Pythagorean theorem again.
20²+15²=x²
400+225=x²
625=x²
√x²=√625
x=25
Answer:
C
Step-by-step explanation:
Find the difference between $94.79 and $89.00 then do (5.79/89)*100 which is 6.50561797753, then round the initial answer so you get 6.50
Have a great day <3
we are given
Jimmy is trying to escape Jane
For finding total distance , we will find distances and then add them
He runs 12 km/hr for 5 minutes
First distance:
speed =12 kh/hr
time=5 minutes
we can change into hour
now, we can plug values
second distance:
speed =17 kh/hr
time=8 minutes
we can change into hour
now, we can plug values
third distance:
speed =6 kh/hr
time=2 minutes
we can change into hour
now, we can plug values
now, we can find total distance
so,
total distance is 3.46667 km...........Answer
Answer:
Down 4 unit (see discussion, could be right 4 units)
Step-by-step explanation:
f(x) = x
G(x) = x - 4
Discussion:
if f(x) = x g(x) = f(x-4) = x-4 ... shift to right 4 units
or g(x) = f(x) - 4 = x -4 ... shift down 4 units
