if £5000 Is placed into a bank account that pays 2% compound interest per year, how much will be in the account after two years

timurjin [86]

Answer:

£5200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 5000 × 0.02 × 2 = 200

I = £ 200.00

The simple interest accumulated

on a principal of £ 5,000.00

at a rate of 2% per year

for 2 years is £ 200.00.

A) .10 d + .25 q = 7.75
B) d + q = 40

Multiplying B) by -.10
B) -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75

Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75

Correct!!

To achive that you have to piant a ring in red, which will have its big diameter equal to the sphere diameter and its small diameter equal to the cube diagonal.

The diagonal of the cube can be calculated using Pithagoras:

$D^2=L^2+L^2$

Where D is the diagonal and L is the side of the cube

The campers in cabin A walked 1/4 of the way to otter ridge (13 miles) How many miles did they walk?

shusha [124]

The question demands that we find a fraction of a given quantity.

The 'of ' means multiplication.

So the total distance of the journey was

$13 \: miles$

But they walked ¼ of the whole journey. We are supposed to find

$\frac{1}{4} \: of \: 13 \: miles$
$\\= \frac{1}{4} \times 13 \: miles$

$= \frac{13}{4} \: miles$

$= 3.25\: miles$

Hence they walked 3.25 miles.
