Step-by-step explanation:
So
Total money = 20
Entrance fee = 1.75
Food = 2.50
Ride = 1.05
Amount spend = 1.75 + 2.05 = 3.8
Left for rides = 20 - 3.8 = 16.2
So rides = 16.2 ÷ 1.05 = 15
I think atleast 15 rides
Answer:
≈ 47.2 m
Step-by-step explanation:
let the height from the sea to the base of lighthouse be h₁
let the height from the sea to the top of the lighthouse be h₂
using the tangent ratio in the right triangle
tan55.1° = 
= 
( multiply both sides by 610 )
h₁ = 610 tan55.1°
tan56.5° = 
( multiply both sides by 610 )
h₂ = 610 tan56.5°
then
height of lighthouse = h₂ - h₁
= 610 tan56.5° - 610 tan55.1°
= 610(tan56.5° - tan55.1° )
≈ 47.2 m ( to the nearest tenth )
A word problem is used to solve problems in mathematics without the explicit use of equations initially.
<h3>What is a Word Problem?</h3>
This refers to the use of words to generate an equation that can be solved by mathematical means.
Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.

Answer:
(2,4) is the solution of the equation.
Step-by-step explanation:
Basically, the solution is the two points intersecting at a point. So, (2,4) is the solution of the equation.
Hoped this helped.
5x²-(-2x²) = 7x²
(-3x)-(-x) = (-3x+x)=-2x
(-2)-(10)=-12
7x²-2x-12
