Answer:
34.8 liters
Step-by-step explanation:
He has 35.8 liters.
He uses 28.6 liters.
Now that tanks has 35.8 liters - 28.6 liters = 7.2 liters
The capacity of the tank is 42 liters, and he has only 7.2 liters.
The fill up will be 42 liters - 7.2 liters = 34.8 liters
Answer:
The slope of the line is 
⇒ B
Step-by-step explanation:
Let us revise the rule of the slope
The rule of the slope of the line is m = 
, where
- (x1, y1) and (x2, y2) are two points lie on the line
∵ The line passes through the point (-3, 1) and point (4, -2)
→ That means one of them is (x1, y1) and the other is (x2, y2)
∴ x1 = -3 and y1 = 1
∴ x2 = 4 and y2 = -2
→ Substitute them in the rule of the slope above to find it
∵ m = 
= 
∴ m =
∴ The slope of the line is
Answer:
x = 7.5
Step-by-step explanation:
We see that in order to find <em>x</em>, we need to use tangent, which is opposite over adjacent.
Step 1: Set up equation
tan37° = x/10
Step 2: Multiply 10 on both sides
10tan37° = x
Step 3: Evaluate
x = 7.53554
Step 4: Round
x = 7.5
Answer:
20 < x < 38.
Step-by-step explanation:
An obtuse angle has a value between 90 and 180.
90 < 5x - 10 < 180
5x - 10 > 90
5x > 100.
x > 20.
5x - 10< 180
5x < 190
x < 38
