Answer:

area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

Step-by-step explanation:

  • let, the shape of the bulletin board is a rectangle,
  • then the perimeter of it = sum of all sides

= 2[length+width] = 2[l+w]

(let l: length, w : width )

  • so, 200 = 2[l+w]

100= l+w ( dividing both the sides by 2)

so, l= 100-w

  • area = length*width=l*w=[100-w]*w
  • therefore,area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

Perform the operation and reduce the answer fully. 1/10 + 2/9 =
larisa [96]
You need to ensure the denominators are the same. To do this you multiply the denominators together.

1/90 + 2/90

However, this is incorrect, as you need to do the same to the numerators, so for the left hand side you multiplied by 9 and for the right hand side you multiplied by 10, so you must do the same for the numerators.

So it should be:

9/90 + 20/90

You can now add this together, to get:

29/90

This is triple checked so I’m not sure why it says reduce the answer fully as that is as far as it can be reduced.

Could someone help me with math? *spam answers not tolerated* THANKS WILL GIVE BRAINLIEST if you have an explanation! Thanks in
Andru [333]

Answer:

r = 3/2

Step-by-step explanation:

ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence (). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get ). If we take 24 and divide it by 16, we get the common ratio of 3/2 (, ).

A circular trampoline has a radius of 8 feet. Wendy wants to buy a cover for the trampoline. What will be the area of the cover
padilas [110]

Answer:

Option (3)

Step-by-step explanation:

Area of a circle is given by the formula,

Area = πr²

Here, r = radius of the circle

Since, radius of the circular trampoline = 8 feet

Area of the cover required for the circular trampoline = π(8)²

                                                                                         = 64π square feet

Therefore, Option (3) will be the answer.

For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the y-axis? Circle
zaharov [31]

Answer:

a) Not parallel to y-axis

b) Not parallel to y-axis

c) Parallel to y-axis

Step-by-step explanation:

The best way to check whether a line passing through two points is parlle to y-axis is by plotting them on graph.

The equation of line: (y-y_1) = \frac{y_2 - y_1}{x_2 - x_1}(x-x_1)

a) The line joining the points (4,12) and ( 6,12) is not parallel to y-axis.

It is parallel to x-axis.  Another two points that can lie on this line are : (5,12) and (\frac{9}{2},12).

b) The line joining the points (\frac{3}{5}, \frac{13}{5}), (\frac{1}{5} ,\frac{8}{5}) is not parallel to y-axis.

Equation of line: 5y - 7.5x = 5.5

Another points that could be lie on this line are (0.6,2) and (0.25,1.475)

c) The line joining the points (0.8, 1.9), (0.8,2.3) is parallel to y-axis because points have the same x-coordinate.

Another points that could be lie on this line are (0.8,2) and (0.8,2.1)
