What is the total payment
required to pay off a promissory
note issued for $500.00 at 10%
ordinary interest and a 180-day
term?

Answers

Answer:

the total payment need to pay is $525

Step-by-step explanation:

Given that

The amount at promissory note issued is $500

The rate of interest is 10%

And, the time period is 180 days

So, the total payment included is

= $500 + ($500 × 10% × 180 days ÷ 360 days)

= $500 + $25

= $525

hence, the total payment need to pay is $525

Answers

Answer:

Curved Surface Area = 48π cm² (≈ 150.72 cm²)

Total Surface Area = 120π cm² (≈ 376.8 cm²)

Step-by-step explanation:

GIVEN :-

Height of cylinder = 4 cmBase radius = 6 cm

TO FIND :-

Area of cylinder

GENERAL FORMULAES TO BE USED IN THIS QUESTION :-

Curved Surface Area of cylinder = 2πrh

Total surface Area of cylinder = 2πrh + 2πr² = 2πr(h + r)

SOLUTION :-

Curved Surface Area of cylinder = 2×π×6×4 = 48π cm² ≈ 150.72 cm²

Total Surface Area of cylinder = 2×π×6(4 + 6) = 120π cm² ≈ 376.8 cm²

2(x + 10) = -60 solve for x

Answers

Answer:

2x + 20 = -60

-20           -20

2x = -80

Divide by 2 on both sides.

X = -40

Answer:

-40

Step-by-step explanation:

2(x + 10) = -60

step 1 distribute the 2 to the x and 10

2 * x = 2x

2 * 10 = 20

we now have 20 + 2x = -60

step 2 subtract 20 from each side

20 - 20 cancels out

-60 - 20 = -80

we now have 2x = -80

step 3 divide each side by 2

2x / 2 = x

-80 / 2 = -40

we're left with x = -40

help po plsss

Answers

Answer:

9.42 m

6.28m

Step-by-step explanation:

to determine the distance walked, calculate the circumference of the circular pool

circumference of a circle = πD

π = 3.14

D = diameter

3 x 3.14 = 9.42 m

Difference in circumference =  π( diameter of bigger circle - diameter of smaller circle)  

diameter of smaller circle = 5 x 2 = 10

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter
