Data:
P (Principal) = $1500
I (Simple Interest) = ?
t (time) = 5 years
r (percentage rate) = 4% = 0.04
Formula:
![I = P*r*t](https://tex.z-dn.net/?f=I%20%3D%20P%2Ar%2At)
Solving (1) <span>Find the interest earned.</span>
![I = P*r*t](https://tex.z-dn.net/?f=I%20%3D%20P%2Ar%2At)
![I = 1500*0.04*5](https://tex.z-dn.net/?f=I%20%3D%201500%2A0.04%2A5)
![\boxed{\boxed{I = 300}}\end{array}}\qquad\quad\checkmark](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7BI%20%3D%20300%7D%7D%5Cend%7Barray%7D%7D%5Cqquad%5Cquad%5Ccheckmark)
Solution (2) <span>Find the balance of the account.
</span>The future value, (Account), of a loan is given by the equation: A = P + I
![A = P + I](https://tex.z-dn.net/?f=A%20%3D%20P%20%2B%20I)
![A = 1500 + 300](https://tex.z-dn.net/?f=A%20%3D%201500%20%2B%20300)
This is a proportion question. We can express this as an equation where the answer is
x:
![\frac{1}{250}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B250%7D%20)
=
![\frac{x}{378}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B378%7D%20)
From there, you can just cross-multiply and divide to get:
![\frac{1 * 378}{250}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20%2A%20378%7D%7B250%7D%20)
A tenth of 250 is 25, so this is roughly
![\frac{375}{250}](https://tex.z-dn.net/?f=%20%5Cfrac%7B375%7D%7B250%7D%20)
or
![\frac{17}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B17%7D%7B10%7D%20)
, so it'll be approximately 1.7 inches on the map.
Answer:
Susy had 60 in the biggening
Step-by-step explanation:
First:
Susy:Mary=2:3
Next:
Susy:Mary=3.5:1.5=7:3
7=210,1=30
Susy had 60 in the biggening
Answer:
D
Step-by-step explanation:
We need to find 2 roots of the quadratic function given and find the greater of the two roots.
We factorize the quadratic and find the two solutions first:
![x^2-6x+5=0\\(x-5)(x-1)=0\\x=1,5](https://tex.z-dn.net/?f=x%5E2-6x%2B5%3D0%5C%5C%28x-5%29%28x-1%29%3D0%5C%5Cx%3D1%2C5)
So,
x = 1
and
x= 5
Out of the two, x = 5 is the greater root.
D is the correct answer.
