Answer:
x=13 feet
Step-by-step explanation:
A ramp is between 1.96 and 1.80 feet, we will take 1.96
and R(x)=1.96 feet: we apply quadratic formula;
, where a=-0.05, b=0.8 and c=-1.96, so
solving
; we take the highest value of x, x=13
Question Translate and solve: Twelve less than x is equal to 51. Enter the equation

Answer:
a = 36.37 cm
c = 18.19 cm
Step-by-step explanation:
to find a, use tan
⇒ tan =
⇒ tan 60 =
tan of 60 is 1.732
⇒ 1.732 =
multiply 21 on both sides
⇒ 1.732 x 21 = x 21
⇒ 36.37 = a
to find c, use sine
⇒ sine =
⇒ sine 60 =
sine of 60 is 0.866
⇒ 0.866 =
muliply 21 on both sides
⇒ 0.866 x 21 = x 21
⇒ 18.19 = c
Consider two integers . We say that
is a multiple of
if
is evenly divisible by
:
Alternatively, we can say that is a multiple of
if there exists an integer
such that
So:
- 4 is not a multiple of 4, because 4/8 is not an integer.
- 8 is a multiple of 8, because 8/8=1
- 20 is not a multple of 8, because 20/8 is not an integer
- 40 is a multiple of 8, because 40/8=5
