Answer:
Sophie has to work 18 hours to buy the sneakers.
Step-by-step explanation:
Since Sophie earns $ 12.80 per hour babysitting, and she has to repay a loan to her parents in the amount of $ 100, and after repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $ 130.40, for write an inequality modeling the number of hours, X, Sophie needs to work to have enough money to buy the sneakers, the following mathematical reasoning must be carried out:
12.80X = 100 + 130.40
12.80X = 230.4
X = 230.4 / 12.8
X = 18
So Sophie has to work 18 hours to buy the sneakers.
Answer:
im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*
Step-by-step explanation:
reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3
i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle and that would be your answer
Answer:
Step-by-step explanation:
Everything is distributed evenly on both ends.
I am joyous to assist you anytime.
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
