Answer:
For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13
Step-by-step explanation:
For the first triangle,
cos(45°)=7/hypotenuse
hypotenuse×cos45=7
hypotenuse×√2/2=7
hypotenuse=14/√2=7√2
We can now find the adjacent side using Pythagorean theorem,
√(7√2)²-7²=7
For the second triangle,
cos(30°)=adjacent/hypotenuse
but cos 30=√3/2
√3/2=adjacent/26(cross multiply and simplify)
26√3/2=13√3
To find the opposite length,
√(26)²-(13√3)²=13
Answer:
32 Hamsters and 18 Birds
Step-by-step explanation:
B+H=50
2B+4H=164
H=50-B
4(50-B)+2B=164
200-4B+2B=164
200-2B=164
-2B=164-200
-2B=-36
-2B/-2=-36/-2
B=18
---
50-18=32
H=32

CHECK: 18+32=50
CHECK: 18 X 2=36 LEGS
CHECK: 32 X 4= 128 LEGS
CHECK: 128+36=164 LEGS IN TOTAL
Answer:
The form is y=mx+b where m is the slope and b is the y-intercept
1)
y=4/3x-5
2)
y=-3/2x+4
y-intercept is (0,4)
4-1/0-2=3/-2=-3/2
3)
y=-2/3x
y-intercept is (0,0)
0-(-2)/0-3=2/-3=-2/3
4)
y=2x-1
9-3/5-2=6/3=2
y-9=2(x-5)
y=2x-10+9
y=2x-1
Step-by-step explanation:
0.6x- 1.2x = 6
-0.6x = 6
x = 6/0.6
x = -10
Pretty sure it is B.) It would be cheaper to return the car on time and pay the refueling cost.
