The width and length of this rectangle are 3 7/12cm and 4 1/12cm respectively.
Hope this helped! ^v^
Solve for x by simplifying both sides.
Exact form :X= 15/2
Decimal form:x=7.5
Mixed number form:x=7 1/2
Answer:
32%.
Step-by-step explanation:
Given:
Probability of having Statistics course is 0.53.
Probability of having computer course is 0.22.
Probability of having both is 0.07.
The probability of the junior Biology majors are ineligible for Bio Research can be calculated as:
<em>P</em>( Ineligible for Bio Research) =1- { P(Statistics) +<em>P</em>( Computer ) -<em>P</em>( Both}
<em>P</em>( Ineligible for Bio Research) =1- { (0.53) + (0.22) - (0.07)
<em>P</em>( Ineligible for Bio Research) = 0.32
Thus, 32% of the junior Biology majors are ineligible for Bio Research.
see the attached figure to better understand the problem
we know that
in the right triangle ABC
cos 56°=AC/AB
where
AC is the adjacent side to angle 56 degrees------> the distance from the surveyor to the building
AB is the hypotenuse-----> 148 ft 2 in
56 degrees------> is the angle of elevation
so
cos 56°=AC/AB---------> solve for AC
AC=AB*cos 56°
AB=148 ft 2 in
convert 2 in to ft
1 ft -----> 12 in
x ft------> 2 in
x=2/12-----> x=0.17 ft
AB=148 ft 2 in-----> 148 ft+0.17 ft------> AB=148.17 ft
AC=AB*cos 56°----> AC=148.17*cos 56°------> AC=82.86 ft
convert 0.86 ft to in
0.86 ft=0.86*12-----> 10.32 in
distance AB=82 ft 10 in
the answer is
the distance from the surveyor to the building is 82 ft 10 in
