45 + 3x and 108 - 4x

45 + 3x = 108 - 4x

3x = 108 - 45 - 4x

3x = 63 - 4x

9x = 63

x = 63/9

x = 7

Emily wants to plant flowers in an area with angular but that is 1 foot by 4.5 ft. the flowers she wants to plant need to be spa
lukranit [14]

Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.

---------------------------

The perimeter of a rectangle of length l and width w is given by:

P = 2(l + w)

In this question, the perimeter is of 1 ft by 4.5, thus, l = 1, w = 4.5, and the perimeter is:

P = 2(1 + 4.5) = 2(5.5) = 11

  • Perimeter of 11 ft.
  • The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:

1 plant - 2/3 ft

x plants - 11 ft

Applying cross multiplication:

\frac{2x}{3} = 11

2x = 33

x = \frac{33}{2}

x = 16.5

At least 8 inches apart(can be more), thus she should buy at most 16 plants.

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute. After 1.5 minutes, the balloon is at an al
azamat

Answer:

The balloon will not reach 2,500 feet after 4 minutes.

Step-by-step explanation:

The equation of the line in the point-slope form is

y-y_1=m(x-x_1)

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute, then the slope is

m=120

After x_1=1.5 minutes, the balloon is at an altitude of y_1=2,150 feet. This means, the line passes through the point (1.5, 2,150).

Substitute the slope and point coordinates into the equation:

y-2,150=120(x-1.5)

We know that after 3 minutes, the balloon is at an altitude of 2,330 feet. Check this:

2,330-2,150=180\\ \\120(3-1.5)=120\cdot 1.5=180\\ \\2,330-2,150=120(3-1.5)

Now, find the height after 4 minutes:

y-2,150=120(4-1.5)\\ \\y=120\cdot 2.5+2,150=300+2,150=2,450

Thus, the balloon will reach only 2,450 feet after 4 minutes.

Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x. 
 
                                      364 = 1.40x

Solving for x gives x = 260.

Thus, the autograph of the basketball player was worth only $260 last year.
