a flower bed is in the shape of triangle with one side twice the length of the shortest side and the third side is 28 feet more thanthe length of the shortest side. find the dimensions if the perimeter is 184 feet.

Answers

x - the shortest side
2x
x + 28

The sum of these must be equal to the perimeter of the flower bed, so

x + 2x + x + 28 = 184

4 x + 28 = 184 Combined like terms

4x = 156 Subtracted 28 from both sides

x = 39 Divided both sides by 4.

So the dimensions are 39 feet, 78 feet, and 67 feet

Final answer:

The problem involves finding the sides of a triangle given the perimeter and conditions for each side. After setting up an equation based on the conditions and solving for x, which is assumed to be the shortest side, the sides of the triangle are found to be 39 feet, 78 feet, and 67 feet.

Explanation:

This is a mathematical problem involving triangles and perimeter. The perimeter of a triangle is the sum of all of its sides. In your case, if we assume the shortest side to be x feet, then the other two sides, according to the question, are 2x feet and x+28 feet. Since the perimeter is 184 feet, these can be added together and set equal to 184, as such:

x + 2x + (x+28) = 184.

Add together like terms:

4x + 28 = 184.

Subtract 28 from both sides:

4x = 156.

Divide both sides by 4:

x = 39 feet.

Therefore, the sides of the triangle are 39 feet, 78 feet (2 * 39), and 67 feet (39 + 28).

Line AB goes through the points A (0, –4) and B (6, 2). Which equation represents line AB?

Answers

the graph equation is in the form y = mx + c
we need to find m - gradient and c - intercept of the graph
since we have been given 2 points we know the x and y coordinates of these 2 points
point A , x = 0 and y = -4
point B , x = 6 and y = 2
substituting these x and y values in y = mx + c form
-4 = m*0 + c
-4 = c
then intercept is -4
substituting x and y in point B
2 = m * 6 + c
since c = -4
2 = 6m - 4
6m = 6
m = 1

since we know m=1 and c = -4
the equation for line AB is
y = 1*x - 4
y = x - 4

Answer: the answer is y + 4 = x

Looking for some furniture for her new apartment, Susan visits the local swap meet in search of something cheap. Knowing that most swap meet vendors willnot accept credit cards and that she will not have any money until her next payday, Susan decides to take out a $200 cash advance on her credit card at an interest rate of 32%. If Susan had no previous balance on her credit card, and she manages to pay off the balance within 1 month, how much will she have to pay in interest?

Answers

Given:
cash advance = 200
interest rate = 32% , I'm assuming this is a per annum rate.
pay w/in a month.

I = 200 * 32% * 1/12
I = 5.33

She will have to pay 5.33 in interest after 1 month.
