a savings account receives 12% simple interest p.a. how long would it take for £30000 to gain £28800 in interest
Elis [28]

Answer:

<h2>8 years</h2>

Step-by-step explanation:

Given,

Principal (P) = £ 30000

Simple Interest ( I ) = £ 28800

Rate (R) = 12%

Time (t) = ?

Now,

t =  \frac{i \times 100}{p \:  \times  \: r}

=  \frac{28800 \times 100}{30000 \times 12}

=  \frac{2880000}{360000}

= 8 \: years

Hence, It would take 8 years.

Hope this helps...

Good luck on your assignment...

Find the volume of the specified cone. Use 3.14 for pi, and round your answer to the nearest whole number. Diameter = 3 cm, Heig
ValentinkaMS [17]

Answer:

16 centimeters cubed

Step-by-step explanation:

Volume of cone is equal to 1/3 * pi * r^2 * h

We are using 3.14 for pi so I'm going to rewrite my formula for volume.

V=1/3 * 3.14 * r^2 * h

We are given diameter is 3 but we need the radius.  We know the radius is half of the diameter so the radius is 1.5 since that is half of 3.

We are given the height is 7.

V=1/3 * 3.14 * 1.5^2 *7

Put into calculator

V=16.485

The whole number that this is closest to is .... 16

So

The Volume of the cone is approximately 16 centimeters cubed.

Solve the proportion for the variable.<br><br> W/5=49/35
hammer [34]

Answer:

7

Step-by-step explanation:

So if w/5 = 49/35, then you can take w/5 and make the denominator 35 by multiplying the top and bottom by 7:

w/5 * 7/7 = 7w/35

So then you have:

7w/35 = 49/35

Which means:

7w = 49

w = 7
