Answer:

4/5

Step-by-step explanation:

Lets do math:

So look we have this many marbles in all:

8+6+6 = 20

and we dont want 6 white marbles so we subtract that

we are left with two numbers 16 and 20 representing the number of non white marbles and the overall number of marbles

to get the probability we divide these:

16/20 which is simplified to 4/5 which is our final answer.

Sam initially invested $4,500 into a savings account that offers an interest rate of 3% each year. He wants to determine the num
FrozenT [24]

Answer:

Principal = $4,500

Rate of interest=3%

Time = x years

We have to find number of years such that

Amount ≤$7020

Amount ≤ Principal + Simple interest

7020≤4500+ S.I

S.I≥7020-4500

S.I≥$2520

Formula for simple interest

S.I=\frac{P\times R \times T}{100}, where P=Principal, R=Rate of interest, T=time

2520≥\frac{4500 \times 3 \times x}{100}

\frac{2520 \times 100}{4500 \times 3} \leq x

x≤\frac{56}{3}

So, the solution set is (0,\frac{56}{3}]

the length of the rectangle is measured as 370mm correct to 2 significant figures.a) what is the upper bound for the length?the
ivanzaharov [21]

Answer:

a) 375

b) 7062.75 mm²

Step-by-step explanation:

b) We need to find the shortest possible width and length to get the smallest possible area.

To get the boundaries for 19.4, we go on to the next significant figure (the hundredths) and ± 5 of them.

The boundaries are, therefore: 19.35 - 19.45

As for the length, we can see they've added 5 units as the measurement is correct to 2 sig' figures, which is the tens.

And so, if we do as we did before, we go to the next sig' figure (the units) and ± 5 of them, we get the boundaries to be 365 - 375.

Now, we just multiply the lower bounds of the length and width to get the minimal/lower-bound area:

365 * 19.35 = 7062.75 mm²

Find the least number which when divisible by 20, 24, 32 and 38 leaves a remainder 5 in cach case
Olegator [25]

Answer:

18245

Step-by-step explanation:

We have to use L.C.M,

L.C.M(20,24,32,38)

2|20,24,32,38

2| 10 ,12 ,16 ,19

2| 5 , 6 , 8 , 19

2| 5 , 3 , 4 , 19

2| 5 , 3 , 2 , 19

L.C.M = 2 x 2 x 2 x 2 x 2 x 2 x 5 x 3 x 19

          = 18240

Now for each case remainder is 5,

So the number is 18240+5

=> 18245
