Answer:
The answer is last option
As we know 1 + tan^2 = sec^2
We are given:
number of kilometers = 875.52 km
time = 38.4 hours
We need to calculate the unit rate, which means that we need to find the number of kilometers in one hour.
To do so, we will simply divide the total number of kilometers by the total time as follows:
unit rate = 875.52 / 38.4 = 22.8 km/hour
Answer:
D. $5.37
Step-by-step explanation:
We need to figure out how much grapes cost per pound
Change the mixed number to an improper fraction
7 1/5 = (5*7+1) /5 = 36/5
$12.89 / 36/5
Copy dot flip
12.89 * 5/36 = 1.79 per lb
If we are purchasing 3 pounds, we will multiply by 3
3 lbs * $1.79 / lb = $5.37
Answer:
∠2=92°
Step-by-step explanation:
Using an angle formula, -8x+144=2x+74
Simplification:
-8x+144=2x+74
-8x+70=2x
70=10x
x=7
Therefore, each angle is 88°
Now, because ∠2 is adjacent to one of 88°, they add up to 180°
Therefore,
180°=88°+∠2
∠2=92°
