Answer:
Step-by-step explanation:
9.54 x 10^6
Tan(A) = opposite / adjacent
if we call opposite "a" and adjacent "b"
tan(A) = a/b
then...
tan(B) = b/a
because it's on the other angle so "b" is now opposite angle B and "a" is adjacent.
So really you just need to take the reciprocal of the given values.
6. tan(A) = 1.25
reciprocal is flipping the value and using it to divide by 1.
you can keep as decimal , 1/1.25 = 0.8
or change to fraction
1.25 = 5/4
tan(B) = 4/5 or 0.8
7. tan(B) = 0.5
1/0.5 = 2
tan(A) = 2
8. tan(B) = 1
tan(A) = 1
Answer:
6 quarters, 6 dimes, and 6 nickels
Step-by-step explanation:
6 quarters=1.50
6 dimes=0.6
6 nickels=0.3
1.5+0.6+0.3=2.40
Answer:
4 and 12
Step-by-step explanation:
a = young
b = old
b = 3a, a+b =2a+8 => a = 4, b = 12
You want one of the values in the ratio to be one for a unit rate. First, write out the ratio. It is 70 miles/2 hours. It's better not to include decimal numbers when you write a ratio when you can, so we're going to make the hours the unit rate. To make 2 -> 1 hour, divide both sides of the ratio by 2. 70/2 = 35.
The unit rate is 35 mi./hr.
Hope that helped you.
