O 14
O24
O 32

Answers

Answer:

√24 because it's lies on between of√16 and√25.

The only square root that falls between 4 and 5 is √24.

What is Number system?

A number system is defined as a system of writing to express numbers.

We can estimate the value of each square root and see which one falls between 4 and 5:

The value of √10 is less than 4 because √10 is, 3.16

√14 is less than 4.5 because  √14 value is 3.76

√24  is greater than 4.5 because √24 value  is 4.89

√32  is greater than 5 because 5 x 5 = 25, and √32 is slightly smaller than 5.

Therefore, the only square root that falls between 4 and 5 is √24.

Find the amount and compound interest on 5000 at 6% per annum for 3 years annual

Answers

Answer:

The amount is 5,955.08

Step-by-step explanation:

Here, we want to calculate compound interest

We can find this by using the compound interest formula

A = P( 1 + r/n)^nt

A is amount

P

is the principal = 5,000

r is the interest rate = 6% = 6/100 = 0.06

n is the number of times per year in which the interest is compounded = 1

t is the number of years = 3

Substituting these values;

A = 5,000(1 + 0.06/1)^3(1)

A = 5000(1.06)^3

A = 5,955.08

If your driving 60miles an hour and you drive for 1hour how far do you travel?​

Answers

Answer:

60 miles

Step-by-step explanation:

1 hour=60 miles

1 hour=60 miles

To solve this problem, we’ll utilize the “time-speed-distance” relationship which is expressed by the formula d = rt, i.e., distance d is equal to speed r multiplied by time t.

The given information in this problem gives us: the speed of r = 60 mi/hr traveled over a distance of 1 mile. We need to find how much time, t, it took to travel a distance d of 1 mile at a speed r = 60 mi/hr, that is:

d/r = t or

t = d/r

Substituting the known values for d and r into the above equation, we have:

t = 1 mi./(60 mi/hr)

t = (1/60) hr.

t = (1/60) hr. (1)

t = (1/60) hr. (60 min./1 hr.)

t = (1/60)(60/1) min.

t = 1 minute ( or 60 seconds) to travel 1 mile at a speed of 60 miles per hour.

Share 39 in the ratio 3:3:7

Answers

Answer:

9 : 9 : 21

Step-by-step explanation:

sum the parts of the ratio, 3 + 3 + 7 = 13 parts

Divide 39 by 13 to find the value of one part of the ratio

39 ÷ 13 = 3 ← value of 1 part of the ratio, then

3 parts = 3 × 3 = 9

7 parts = 7 × 3 = 21

Then 39 in ratio 3 : 3 : 7 = 9 : 9 : 21
