Answer:
1.25 inches
Step-by-step explanation:
200 miles/ 50 miles = 5 inch / x
x = (50 x 5) / 200 = 250 / 200 = 1.25
Answer:
Step-by-step explanation:
cot x=√3
tan x=1/√3=tan π/6,tan (π+π/6)
=tan π/6,tan (7π/6)
x=π/6,7π/6
x
Answer:
t = 6 4/25 hours
Step-by-step explanation:
The formula to find out how long it takes them to do the job is
1/m + 1/ a = 1 /t
where m is the time for Matthew to do the job
a is the time for Arianna to do the job
and t is the time for them to do the job together
m = 14 hours
a = 11 hours
Substituting what we know
1/14 + 1/11 = 1/t
Multiplying by 154t (14*11*t) so we can clear the fractions
154t*(1/14 + 1/11) = 1/t* 154t
11t + 14t = 154
Combine like terms
25t = 154
Divide by 25
t = 154/25
t = 6 4/25 hours
Question number 9
Angle 1 is 75. This is because If two parallel lines are cut by a transversal, the corresponding angles are congruent.
Angle 2 is 105. This is because If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.
Question number 10
Angle 1 is 120. This is because If two parallel lines are cut by a transversal, the corresponding angles are congruent.
Angle 2 is 60. This is because If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.
