Answer:
its a 3.5
Step-by-step explanation:
Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = 
finding d:
⇒tan 63 = 
tan of 63 is 1.963
⇒ 1.963 = 
multiply 3.1 on both sides
⇒ 1.963 x 3.1 =
x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 = 
tan of 45 is 1
⇒ 1 = 
multiply 7 on both sides:
⇒ 1 x 7 =
x 7
7 = n
Answer:12 5/8
Step-by-step explanation:
Add the whole numbers together. 3 + 9 = 12
Multiply 1/4 so that it will have the same dnominator as 3/8. 2(1/4)= 2/8
Add the fractions together. 2/8 + 3/8 = 5/8.
Add the whole number and fraction to get a mixed number. 12 + 5/8 = 12 5/8
Not sure what alive by graphing means, but these are the equations on a graph. Red is y=4x+7 and blue is y=-3x.
