Answer:

Length=15cm

Hope this answer is right!!

Step-by-step explanation:

Length be 3 cm longer than the breadth.

So, x=y+3

Perimeter = 2(x+y)54

The sum of all but one interior angle of a heptagon is 776°. What is the measure of the final interior angle? 42º 56º 124º 3
weqwewe [10]

The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

<h3>What is the measure of the missing interior angle in a heptagon?</h3>

Heptagons are polygons with seven sides, seven vertices, seven <em>interior</em> angles and seven <em>central</em> angles. Herein we know the value of the sum of six interior angles and we need to know the measure of the seventh <em>interior</em> angle. We can determine the measure of the seven interior angles by using the following expression:

θ = (n - 2) · 180°, where n is the number of sides of the polygon.     (1)

If we know that n = 7, then sum of the internal angles in the heptagon is:

θ = (7 - 2) · 180°

θ = 900°

And the measure of the final interior angle is found by subtraction:

θ₇ = 900° - 776°

θ₇ = 124°

The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

Suzanne bought a sofa for d dollars and paid 8% sales tax. Write two different expressions that represent the total number of do
slavikrds [6]

Answer:

The total money spent by Suzanne for sofa is = c=d+0.08d or c=d(1+0.08)

Step-by-step explanation:

Let the overall cost be represented by = c

Cost of the sofa is = $ d

Sales tax paid for the sofa is = 8%

So, this becomes 8% of d = 0.08d

So, the total money spent by Suzanne for sofa is =

c=d+0.08d or c=d(1+0.08)

Solve for g in the proportion.<br> 143<br> g<br> 540<br> 858
Doss [256]

The value of g from the given proportion is 227.2

<h3>Ratio and proportions</h3>

Fractions are written as a ratio of two integers. For instance a/b is a fraction where a and b are integers.

Given the following proportion shown below;

143/g = 540/858

In order to determine the value of g,  we will cross multiply to have:

540g = 143 * 858

Simplify

540g = 122694

Divide both sides by 540

540g/540 = 122694/540

g = 122694/540

g = 227.2

Hence the value of g from the given proportion is 227.2
