Kaylis [27]

Answer:

$3x+$5y=C and the total cost is $ 78

Step-by-step explanation:

the equation first is going to be  $3x+$5y=C

x: small balloons

y: large balloons

c: total cost

Now to find the how much the total cost is, you should substitute the variables  and then solve the equation.

x: 11

y:9

3(11)+5(9)= 33+45

78

Answer:

  244 tiles

Step-by-step explanation:

These "border" problems can be a little tricky.

The tiles are 1 ft square, so an integer number of them fit along each of the sides. The 40-ft side will take 40 tiles for its border, and the 80-ft side will take 80 tiles.

The total number of tiles along each of the four sides is ...

  40 + 80 + 40 + 80 = 240 . . . tiles

However, there is also a tile in each of the corners. There are 4 of those, so the total number of tiles surrounding the pool is ...

  240 +4 = 244 tiles

__

<em>Alternate solution</em>

For a border of width w, the outside area of the pool plus the border is ...

  A = LW = (80 +2w)(40 +2w) = 80·40 +240w +4w²

The area of the pool is ...

  A = LW = (80)(40) = 80·40

Subtracting the area of the pool from the total area including the border gives ...

  border area = (80·40 +240w +4w²) -(80·40) = 240w +4w²

We know the width of the border is 1 foot, so w=1 and the border area is ...

  border area = 240·1 +4·1² = 244 . . . . square feet

Each tile is 1 square foot, so 244 tiles are needed for the border.

_____

It can help to draw yourself a diagram. It can also help to make a small model using blocks, Scrabble tiles, Legos, jigsaw puzzle pieces, squares cut from paper, or even coins (pennies). Anything that will give you an idea of how to count the tiles required to make a border can be helpful.

Type the correct answer in each box. Use numerals instead of words.
Natali5045456 [20]

Given:

Consider the given function is f(x)=-(x+1)(x-3)(x+2).

To find:

The remaining zero and y-coordinate of y-intercept.

Solution:

We have,

f(x)=-(x+1)(x-3)(x+2)

For zeros, f(x)=0.

-(x+1)(x-3)(x+2)=0

(x+1)(x-3)(x+2)=0

(x+1)=0,(x-3)=0,(x+2)=0

x=-1,x=3,x=-2

So, three zeros of given function are -1, 3 and -2.

Putting x=0 in the given function, we get

f(0)=-(0+1)(0-3)(0+2)

f(0)=-(1)(-3)(2)

f(0)=-(-6)

f(0)=6

So, the y-coordinate of y-intercept of the given function is 6. It means the y-intercept is at point (0,6).

Therefore, the zeros of the function f(x)=-(x+1)(x-3)(x+2) are –1, 3, and -2 and the y-intercept of the function is located at (0,6).

Can u find the area of these please
Schach [20]
Area of a rectangle can be calculated by multiplying the length by the height.
So:

l x w
3 x 13
39 cm squared

Area of a triangle can be calculated by multiply the length by the height and dividing by two. So:

1/2 x l x w
1/2 x 10 x 8
40 m squared
