Answer:
the answer is D
Step-by-step explanation:
60x - 48 is correct
Answer:
Step-by-step explanation:
a. p=2200+60n
b. p=2200+60(26)
p=2200 plus 1560
p=3760
Weight goes 4 feet down before hitting the pool
therefor the pool is 12-4 ft or 8ft deep
(12)+(-4)=8 is the sum of integers
12 is an integer
-4 is an integer
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
1,000 yes 25% of 4000 is 1000
