I'm not sure but I think it's 40 water stations...
Answer:
x = 10
Step-by-step explanation:
First look at the big overall triangle.
It has a right angle and another angle of 44; therefore the missing angle is (since the sum of angles inside a triangle is 180)
180 - 90 - 44 = missing angle
missing angle (top) = 46; now the angle of a straight line is 180 and they give you 56° which has a supplementary angle of 180 - 56 = 124°.
Now we know that the triangle that include the x has angles 46° (missing top angle), and supplementary angle of 124°. Therefore
x = 180 - 46 - 124
x = 10
Answer: May
Step-by-step explanation: 40/7.3333 equals 5.45 months basically 5 and a half of a month so 5 months which is may
Answer:
Step-by-step explanation:
Given:
See attachment for rectangle LINT
Required
Calculate its perimeter
From the attachment:
Considering triangle LYT, we apply Pythagoras theorem.
Where:
The formula becomes:
Take positive square root of both sides
Next, we calculate the length of NT.
By comparing triangles LYT and NYT
We make use of the following equivalent ratios to solve for NT
Convert to fractions
Make NT, the subject:
The perimeter (P) is then calculated as:
Where
and -- opposite sides of rectangle.
So:
Substitute values for NT and LT
<em>Hence, the perimeter is 22.75 units</em>
Answer:
a)
s= 6t-t² --> v = 6 -2t --> a = -2
s=t²-6t --> v = 2t-6 --> a = 2
s= t²-9t+24 --> v = 2t -9 --> a = 2
b)
v = 6 -2t = 0 --> t = 3
v = 2t-6 = 0 --> t = 3
v = 2t -9 = 0 --> t = 9/2
Step-by-step explanation:
si s(t) es la distancia, la velocidad es la primera derivada v(t) = s'(t)
y la acceleracion es la segunda derivada : a(t)= v'(t) = s''(t)
s= 6t-t² --> v = 6 -2t --> a = -2
s=t²-6t --> v = 2t-6 --> a = 2
s= t²-9t+24 --> v = 2t -9 --> a = 2
