Answer:
6
Step-by-step explanation:
8.5 can also be written as 8.50. If you take the digits in the hundredths place, 10 and 4, and subtract them, you get 6.
Answer:
the equation of the above is
y= 10x - 5
Answer:
1-nonlinear it is not consistant
2- a increasing, b constant, c decreasing
3- 'a' walking away from hole, 'b' rests, 'c' goes back to hole (b could also be gather, as in food)
4- 8cm per second
work 16cm/2sec=8cm/1sec
Step-by-step explanation:
Answer:
m∠C = 44°
Step-by-step explanation:
In ΔCDE,
m∠C=(4x−16) ∘
m∠D=(6x−1) ∘
m∠E=(4x−13) ∘ .
The sum of angles in a triangle = 180°
Step 1
We solve for x
m∠C + m∠D + m∠E
(4x−16)° + (6x−1)° + (4x−13)° = 180°
4x - 16 + 6x - 1 + 4x - 13 = 180°
4x + 6x + 4x -16 - 1 - 13 = 180°
14x - 30 = 180°
14x = 180+ 30
14x = 210
x = 210/14
x = 15
Step 2
Find m∠C
m∠C = (4x−16)°
m∠C = (4 × 15 - 16)°
m∠C = (60 - 16)°
m∠C = 44°
I see 3 right triangles.
Right triangle: a² + b² = c²
a = long leg ; b = short leg ; c = hypotenuse
hypotenuse = EH
a = 6 - 3 = 3
b = 3 - 1 = 2
c² = 3² + 2²
c² = 9 + 4
c² = 11
c = √11
c = 3.32
hypotenuse = FG
a = 3 ; b = 1
c² = 3² + 1²
c² = 9 + 1
c² = 10
c = √10
c = 3.16
hypotenuse = EF
a = 3 ; b = 2
c² = 3² + 2²
c² = 9 + 4
c² = 11
c = √11
c = 3.32
perimeter = 3.32 + 3.16 + 3.32 + 2 = 11.8
