Answer:
Soil bacteria convert nitrogen gas into ammonia, nitrites, and then nitrates. Nitrates are then absorbed by producers.
Step-by-step explanation:
.
2 times 35 = 70x
2 times 15 =30
70x+30
Answer:
yes
Step-by-step explanation:
We are to determine if 6 yards is enough t to go round the perimeter of the window
The length is not given, so we have to determine the length from the area
Area of a rectangle = length x breadth
19.25 = 3.5 x length
length = 5.5 feet
Perimeter = 2 x ( length + breadth )
2 x (5.5 + 3.5) = 18 feet
We need to convert the string to foot
1 yard = 3 foot
6 x 3 = 18 foot
the string and the perimeter are equal, so it is enough
Answer
given,
greater compressive strength = 6,000 psi
mean compressive strength(μ) = 7000 psi
standard deviation (σ) = 420 psi
P(X < 6000)
Z = - 2.38
P(Z<-2.38) = Area to left - 2.38
from Z table
P(X < 6000) = P(Z<-2.38) = 0.0087
P(fail) = P(X< 6000) = 0.0087 = 0.87
So you know that the triangle is a right triangle, and that means that the work is pretty straightforward:
You 'know' the measure of angle x and one of the legs of the triangle, so when trying to find the distance of the second leg of the triangle, use the Tangent function because the tangent of angle x = opposite leg / adjacent leg.
Since we know the measure of the adjacent leg and the angle measure, solve for the opposite leg's measure:
tanx = opposite / y
opposite = y * tanx
This means that the distance between the Earth and the Moon is equal to the tangent of the angle of the sun's rays between the Earth and Moon times the distance between the Sun and Earth.
