Answer:
<h2>90 min or 1hr 30 mins</h2>
Step-by-step explanation:
Even though the options to choose from are not given in this question we can try and lay our hand on the most likely equation for the number of minutes Jack reads his book.
firstly on a daily Jack reads a total of = 8+10 = 18 mins
He attends school from Mon- fri = 5 days
Now on a weekly basis jack reads = 5*18
in other words, the equation is simply the number of days times the time spent to read his book per day
hence this is = 90 min or 1hr 30 mins
Answer:
D. -2/3
Step-by-step explanation:
Since it is going down, it is negative
Think of this: Rise/Run
In this case, rise is when you are going up or down the graph
Run is when you are going to the right of the graph
Let's use 2 points (0,3) and (3,1)
Since you are going three points to the right we are going to put 3 in for run
You are going 2 places down, so we are going put -2 in for rise
This gives us -2/3
Another way to do this is (1-3)/(3-0) = -2/3
Answer: 6 years
Step-by-step explanation:
Formula to calculate compound amount:
, where P= Principal , r=rate of interest, t= time
Given: P = £400, r = 3% = 0.03 , A= 475
Required equation: ![400(1+0.03)^t\geq475](https://tex.z-dn.net/?f=400%281%2B0.03%29%5Et%5Cgeq475)
![400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875](https://tex.z-dn.net/?f=400%281.03%29%5Et%5Cgeq475%5C%5C%5C%5C%5CRightarrow%5C%20%281.03%29%5Et%5Cgeq%5Cdfrac%7B475%7D%7B400%7D%5C%5C%5C%5C%5CRightarrow%5C%20%281.03%29%5Et%5Cgeq1.1875)
Taking log on both sides , we get
![t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6](https://tex.z-dn.net/?f=t%20%5Clog%201.03%5Cgeq%5Clog1.1875%5C%5C%5C%5C%5CRightarrow%5C%20t%280.0128372%29%5Cgeq%280.0746336%29%5C%5C%5C%5C%5CRightarrow%5C%20t%5Cgeq%5Cdfrac%7B0.0746336%7D%7B0.0128372%7D%3D5.81385%5Capprox6)
Hence, he needs to invest the money for 6 years to get atleast £475.
