Answer:
Step-by-step explanation:
3x + 4 + 8x + 4 = 140 degree (sum of two interior opposite angle is equal to the exterior angle formed)
11x + 8 = 140
x = 140 - 8
x = 132 /11
x = 12
angle S = 3x + 4
=3*12 + 4
=36 + 4
=40 degree
89 + 5x - 7 = 14x + 1
82 + 5x = 14x + 1
82 - 1 = 14x - 5x
81 = 9x
81/9 = x
9 = x
angle H = 5x - 7
=5*9 - 7
=45 - 7
=38 degree
Answer:
x = 3 - t and y = 4 - 2t
Step-by-step explanation:
We have to find such a set of parametric equations for the given equation which result in an x-value equal to 3 and a y-value equal to 4 when t is substituted as 0.
There can be more than 1 possible answers to this problem. You have to use hit and trial method to come up with the correct set of parametric equations. One of the possible set is:
y = 4 - 2t , x = 3 - t
For t = 0
x= 3 and y = 4
Hence, the condition is satisfied.
Now checking if these parametric equations result in given equation or not.
From second equation, we get:
t = 3 - x
Using this value in first equation, we get:
y = 4 - 2(3 - x)
y = 4 - 6 + 2x
y = 2x - 2
Which is the given equation.
Hence the set of parametric equation is:
x = 3 - t and y = 4 - 2t
Answer: 0.6 liters per kilometer
Step-by-step explanation:
(A) 475L - 50km
(B) 375L - 200km
Subtract liters.
475-375=100L
Subtract km
200-50=150km
Divide liters per km
100/150=0.6L/km
Let's sort the data
9.9, 10.2, 10.6, 10.6, 11.9
The median is clearly 10.6, the middle value. The sum is 53.2 so the mean is 53.2/5 = 106.4/10 = 10.64
mean - median = 10.64 - 10.6 = 0.04
Answer: 0.04
Answer:
30
Step-by-step explanation:
Similar figures
63/54 = 35/X
X = 35 × 54/63
X = 30
