How much will have to deposit into an account that pays 5.25% simple interest today, in order to earn $345.45 interest in seven
Ann [662]

To earn $345.45 simple interest in 7 years, you have to invest $940.

<u>Step-by-step explanation:</u>

Step 1:

Given details are Simple Interest Rate (R) = 5.25%, Simple Interest (SI) = $345.45, Time (T) = 7 years

Step 2:

Use the above details to find principal using the formula for Simple Interest (SI) = PRT/100

⇒ 345.45 = (P × 5.25 × 7)/100

⇒ 34545 = 36.75 P

⇒ P = $940

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 500(1.075)120x = 100.000
Volgvan

Answer:

The solution is:

x = 0.61

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

500(1.075)^{120x} = 100000

(1.075)^{120x} = \frac{100000}{500}

(1.075)^{120x} = 200

To find x, we have to apply log to both sides of the equality.

We also have that:

\log{a^{x}} = x\log{a}

So

\log{(1.075)^{120x}} = \log{200}

120x\log{1.075} = 2.30

120x*0.03 = 2.30

3.77x = 2.30

x = \frac{2.30}{3.77}

x = 0.61

The ratio of 3 km to 1800 m is​
Ugo [173]
5 : 3


D1 = 3km = 3000 m (1km = 1000m)
D2 = 1800m


Ratio of D1:D2
=3000/1800
=1000/600 (dividing by 3)
=10/6 (dividing by 100)
=5/3 (dividing by 2)

= 5 : 3
