Answer:
Step-by-step explanation:
basically it's when the order changes, but the value doesnt.
example: a*b=b*a
Answer:
306.8 feet
Step-by-step explanation:
Refer the attached figure .
A surveyor moves 160 feet away from the base of the pole i.e. ED = 160 m
Referring the image .
AC=ED=160 m
A transit i.e. AE is 6 feet tall.
AE = CD=6 feet
With a transmit the angle of elevation to the top of the pole to be 62° i.e. ∠BAC = 62°
To Find BC , use tigonometric ratio.
Now, the height of the pole = BC+CD =300.8+6=306.8 feet
Hence the height of the pole is 306.8 feet
We know that
[area of a circle]=pi*r²
r=5 in
[area of a circle]=pi*5²---------> 78.5 in²
if 2pi radians ( full circle) has an area of-------------------> 78.5 in²
1.5 radians------------------------------------------> X
X=1.5*78.5/2pi---------> 18.75 in²
the answer is
<span>the area of the sector formed by a central angle is </span>18.75 in²
Answer: 275 adults and 130 children
Step-by-step explanation:
<u>First, find the value of one variable by rearranging a equation:</u>
<u />
<u>Substitute it into the other equation and solve for a:</u>
<u />
<u>Use the a-value to find b by substituting it into the rearranged equation:</u>
<u />
<u>Therefore, the answer would be:</u>
<u />
41.625 feet long because it is the product of 4 5/8*9
