Answer:
ZYX- CBA
Step-by-step explanation:
ZYX is backwards
so cba needs to be too
3y-3y+-4=9y-3y-8
-4=6y-8
-4+8=6y-8+8
4=6y
y=4/6
y=2/3 (66.6%)
Answer:
ln(2) + 3ln(a) - 4ln (b)
Step-by-step explanation:
ln(2a^3 /b^4)
We know that ln(x/y) = ln (x) - ln y
ln(2a^3 ) - ln (b^4)
We know that ln (xy) = ln x + ln y
ln(2) + ln(a^3 ) - ln (b^4)
We know that ln(x^y) = y ln (x)
ln(2) + 3ln(a) - 4ln (b)
Answer:
Step-by-step explanation:
d = r * t
Let the time at 59 miles / hour be t
59*t + 57* (4.5 - t) = 259.5 Remove the brackets
59*t + 256.5 - 57*t = 259.5 Combine the left
2t + 256.5 = 259.5 Subtract 228 from both sides
2t = 259.5 - 256.5 Combine
2t = 3 Divide by 2
t = 1.5
So he spent 1.5 hours going at 59 miles per hour
He spent 4.5 - 1.5 = 3 hours going 57 miles per hour.
Answer:
The markup amount on the cost 39.99 $ will be: 8.78 $
Step-by-step explanation:
Given
- The cost = 39.99 (Let say in $)
As
22% = 0.22
The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22
so
Markup amount = 0.22 × 39.99
= 8.78 $
Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $
