Answer:

4

Step-by-step explanation:

Proportionality between skein values

8:2=4:1

Proportionality between cost values

28:7=4:1

The variation(both the skein values and cost values) has the constant of 4 ie the 1st skein value × 4= the last skein value & the 1st cost value × 4=the last cost value

A regular pentagon is shown. A regular pentagon has side lengths of 9.4 centimeters and a radius of 8 centimeters. What is the l
Angelina_Jolie [31]

Answer:

6.5 cm

Step-by-step explanation:

The computation of the length of the apothem is shown below:

Given that

The side length is 9.4 centimeters

And, the radius is 8 centimeters

Now based on the above information

As per the attached figure  

AB = 8 cm

BC = 9.4 ÷ 2 = 4.7 cm

Now apply the pythagoras theorem

AB^2 = BC^2 + AC^2

8^2 = 4.7^2 + AC^2

AC^2 = 41.91

AC = 6.47 cm

= 6.5 cm

Find the principal which will yield simple interest of N55.60 for 1yr 6 months at the rate of 2%
Norma-Jean [14]

There should be a point the line is going through, (1,2).

We have given that,

N55.60 for 1yr 6 months at the rate of 2%

We have to determine the principal which will yield simple interest of N55.60 for 1yr 6 months at the rate of 2%.

<h3>What is the simple interest?</h3>

A = P (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

x = inches

y = miles

per 1 inch = 2 miles

so on the graph, there should be a point the line is going through, (1,2).
