Answer:
A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.
(this may be more of an architect's job, as they are the ones that design the houses)
or
An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.
75 buttons
Gives 15 buttons to Jake.
75 - 15 = 60
15/75
15 ÷ 75 = 0.2
0.2 × 100 = 20
20%
Emily gave Jake 20% of the buttons!
Let m be the total mileages for each company.
Company A.
The total cost for m miles for this company is:
Company B.
The total cost for miles for this company is:
Now, we need to know for what mileage company A charges more than company B, this means:
Solving for m we have:
Therefore for m>140 (that is for more than 140 miles) company A will charge more tan company B.
Answer:
infinite solutions
Step-by-step explanation:
-3v-2=-2-8v+5v
Combine like terms
-3v-2 = -2 -3v
Add 3v to each side
-3v-2+3v = -2 -3v+3v
-2 = -2
Since this is always a true statement, there are infinite solutions
Answer:
Step-by-step explanation:
Let X be length of life of the participants in the plan.
Given that X is N(68,3.5)
We convert this to standard normal score z using
a) proportion of the plan recipients that would receive payments beyond age 75=
b) proportion of the plan recipients die before they reach the standard retirement age of 65=
c) x for 86% ceased
