Normally, compasses are circles
you didn't give us a height so we only need to compute the area of the face of the compass


area of circle=pir²
2r=d so



area=12.56
12.56=pir³
aprox pi=3.141592
divide both sides by pi or 3.141592
3.99=r³
sqrt both sides
about 2
2=r

2r=d
2(2)=d
4=d

diameter is 4cm

What number is it that, when multiplied by 18,27,36,45,54,63,72,81, or 99, gives a product in which the first and last figures a
allsm [11]

The given multipliers are factors of 9, the possible number will have 1 as first and last digit which gives the number as 101

<h3>How can the correct number be found?</h3>

The given numbers are;

18, 27, 36, 45, 54, 63, 72, 81, 99

Given that the first and the last figures are those of the multipliers, we have;

The first and last and last digit of the number can be 1, which gives;

Possible numbers includes; 11 and 101

By trying the possible numbers, the difference found is presented as follows;

99 × 11 = 1089 (The first and the last digit are not the same as the multiplier)

  • 99 × 101 = 9999 (First and last digit are not the same as the multiplier)

90 × 11 = 990

90 × 101 = 9090

The correct option is therefore 101

  • The number is 101

Sam invested $48,000 some at 6% interest and the rest at 10% . How much did he invest at each rate if he received $4,000 in inte
emmainna [20.7K]

<u>Answer with step-by-step explanation:</u>

We are given that Sam invested $48,000 at 6% interest and the rest at 10%. Given that he received $4,000 interest in one year, we are to find how much he invest at each rate.

Assuming the amount invested at 6% interest rate as x, we can write it as:

(\frac{6}{100} \times x)+(\frac{10}{100} \times [48000-x])=4000

0.06x+0.1(48000-x)=4000

0.06x+4800-0.1x=4000

0.1x-0.06x=4800-4000

0.04x=800

x=20000

So the amount invested at 6% = $20,000 and amount invested at 10% = (48000 - 20000) = $28,000
