Step-by-step explanation:
<A + <B = 180
6x-35+ 3x+53=180
9x=162
x=18
<A= 6(18) -35
<A= 73°
In this big ol' word problem, this is just an instance of basic multiplication/division.
If it takes it 1 hour for 3 meters...
12 ÷ 3 = 4.
It would take 4 hours for the water level to change to 12 meters.
Total charge at park, T = 2×charge on adults + 4×charge on children .
T =$(2×16 + 4×10)
T = $72
Now, Melissa's father paid $100 .
Amount her father get back is :
A = $( 100 - 72 )
A = $28
Therefore, her father get $28 back.
Hence, this is the required solution.
Answer:
B
Step-by-step explanation:
Given 2 quantities that vary directly, then the graph must pass through the origin.
Nikiya's graph is the only one to do this ⇒ B
This is an obtuse triangle.
Acute triangles have angles of less than 90º.
Right triangles have an angle equal to 90º.
Obtuse triangles an angle more than 90º.
