Answer:

3 inches

Step-by-step explanation:

(14+2x) × (15+2x) = 2(14×15)

210 +30x +28x + 4x² = 420

4x² + 58x - 210 = 0

2x² + 29x - 105 = 0

2x² + 35x - 6x - 105 = 0

x(2x + 35) - 3(2x + 35) = 0

(x - 3)(2x + 35) = 0

x = 3, -35/2(not possible)

The difference between the simple and compound interest for a certain sum of money of 3 years at 5% per annum is Rs.61.0. Find t
miss Akunina [59]

5% interest compounded annually for 3 years multiplies the initial balance by

... 1.05^3 = 1.157625

5% simple interest for 3 years multiplies the initial balance by 1 + 3*0.05 = 1.15.

The difference of these multipliers is

... 1.157625 - 1.15 = 0.007625

If the difference in account balance is Rs 61.00, then the invested principal amount P is

... P*0.007625 = 61.00

,.. P = 61.00/0.007625 = 8000.00

The sum of money is Rs 8000.

Answer:

<u>7 squares</u>

Step-by-step explanation:

<u>Key skills: Counting, Averages</u>

1) Based on what I counted, there are 11 columns, and 53 squares. If you want an average of 5 squares per column and you have 12 columns, the total number of squares you want is 60.

2) Since there are already 53 squares present, you need 60-53 = <u>7 squares</u> more.

<em>Hope you understood and have a nice day!!</em>

Ava is 23 cm taller than Olivia, and Olive is half the height of Lucas. If Lucas is1.78 m tall, how tall are Ava and Olive? Expr
bonufazy [111]
Ava's Height = a
Olivia's Height = o
Lucas' Height = l

We know from the question that;

o =  \frac{1}{2}l

If Lucas is 1.78m tall, then he is 178cm tall, so l = 178

o = \frac{1}{2}178

o = 89

We also know that;

a + 23 = o

As we have worked out that o = 89,

a + 23 = 89

a = 89 - 23

a= 66

\boxed  {a = 66cm, o = 89cm}
