Answer:

5 ft

Step-by-step explanation:

Total area of turf and flower bed is [tex]1200\ \text{ft}^2[/tex]

Turf dimensions is 20 feet by 30 ft

Area of turf = [tex]20\times 30=600\ \text{ft}^2[/tex]

Area of flower bed = [tex]1200-600=600\ \text{ft}^2[/tex]

Let [tex]x[/tex] be the width of the flower bed so area of flower bed is

[tex]2\times 30x+2(20+2x)x=600\\\Rightarrow 30x+20x+2x^2=300\\\Rightarrow 2x^2+50x-300=0\\\Rightarrow x^2+25x-150=0\\\Rightarrow x=\dfrac{-25\pm \sqrt{25^2-4\times \:1\times \left(-150\right)}}{2\times \:1}\\\Rightarrow x=5,-30[/tex]

So, width of the flower bed is 5 ft.

Answer:

B. 21.2

Step-by-step explanation:

Perimeter of ∆ABC = AB + BC + AC

A(-4, 1)

B(-2, 3)

C(3, -4)

✔️Distance between A(-4, 1) and B(-2, 3):

[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] AB = \sqrt{(-2 - (-4))^2 + (3 - 1)^2} = \sqrt{(2)^2 + (2)^2)} [/tex]

[tex] AB = \sqrt{4 + 4} [/tex]

[tex] AB = \sqrt{16} [/tex]

AB = 4 units

✔️Distance between B(-2, 3) and C(3, -4):

[tex] BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] BC = \sqrt{(3 - (-2))^2 + (-4 - 3)^2} = \sqrt{(5)^2 + (-7)^2)} [/tex]

[tex] BC = \sqrt{25 + 49} [/tex]

[tex] BC = \sqrt{74} [/tex]

BC = 8.6 units (nearest tenth)

✔️Distance between A(-4, 1) and C(3, -4):

[tex] AC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] AC = \sqrt{(3 - (-4))^2 + (-4 - 1)^2} = \sqrt{(7)^2 + (-5)^2)} [/tex]

[tex] AC = \sqrt{47 + 25} [/tex]

[tex] AC = \sqrt{74} [/tex]

AC = 8.6 units (nearest tenth)

Perimeter of ∆ABC = 4 + 8.6 + 8.6 = 21.2 units

Answer:

70 km/h

Step-by-step explanation:

A car is travel 210 km in 3 hours.

Distance, d = 210 km

Time, t = 3 hours

We can find the speed of the car. The speed of an object is equal to the total distance divided by time taken.

v = d/t

Substitute the values,

[tex]v=\dfrac{210\ km}{3\ h}\\\\v=70\ km/h[/tex]

So, the required speed of the car is 70 km/h.

Answer:

The equation of the line is [tex]y = -\frac{x}{4} - 3[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(the value of y when x = 0).

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

Line perpendicular to y = 4x + 4.

This line has slope 4, so our line will have slope:

[tex]4m = -1[/tex]

[tex]m = -\frac{1}{4}[/tex]

So

[tex]y = -\frac{x}{4} + b[/tex]

Through (0, -3)

This means that [tex]b = -3[/tex]

So

[tex]y = -\frac{x}{4} - 3[/tex]

Answer:

h ≅ 16.29 cm

[tex]\mathbf{\dfrac{dh}{dt}= -0.1809 \ cm/s}[/tex]

Step-by-step explanation:

From the conical funnel;

Let the adjacent line at the base of the cone be radius (r) and the opposite ( vertical length) be the height (h)

Then;

[tex]tan \theta= \dfrac{r}{h}[/tex]

[tex]tan \theta= \dfrac{8}{16}[/tex]

[tex]tan \theta= \dfrac{1}{2}[/tex]

∴

[tex]\dfrac{r}{h} = \dfrac{1}{2}[/tex]

[tex]r = \dfrac{h}{2}[/tex]

The volume (V) of the cone is expressed as:

[tex]V = \dfrac{1}{3}\pi r ^2 h[/tex]

[tex]V = \dfrac{1}{3}\pi (\dfrac{h}{2})^2 h[/tex]

[tex]V = \dfrac{\pi h^3}{3\times 4}[/tex]

[tex]\dfrac{dv}{dt} = \dfrac{3 \pi h^2}{3 \times 4} \dfrac{dh}{dt}[/tex]

[tex]\dfrac{dv}{dt} = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}[/tex]

Given that:

[tex]\dfrac{dv}{dt} = 12 \pi[/tex]

Then:

[tex]-12 \pi = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}[/tex]

[tex]- \int 48 \ dt = \int h^2 \ dh[/tex]

[tex]\dfrac{h^3}{3}= -48 t + c[/tex]

[tex]At \ t = 0 \ ; h = 0[/tex]

∴

[tex]\dfrac{0^3}{3} = -48(0) + c[/tex]

c = 0

So;

[tex]\dfrac{h^3}{3}= -48 t + 0[/tex]

[tex]\dfrac{h^3}{3}= -48 t[/tex]

t = 30

[tex]\implies h = (-48(30))^{1/3}[/tex]

h = 16.2865

h ≅ 16.29 cm

Thus;

from [tex]-12 \pi = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}[/tex]

[tex]\dfrac{-12 \pi} { \dfrac{ \pi h^2}{4} } =\dfrac{dh}{dt}[/tex]

[tex]\dfrac{dh}{dt} = \dfrac{-12 \pi} { \dfrac{ \pi h^2}{4} }[/tex]

[tex]\dfrac{dh}{dt}=\dfrac{-12 \times 4} { {16.29^2} }[/tex]

[tex]\mathbf{\dfrac{dh}{dt}= -0.1809 \ cm/s}[/tex]

hello, it's easy❤

answer is -9

Answer:

$2448 in a year

Step-by-step explanation:

$63,648 ÷ 52 = $1224 a week (this would be how much he earns per week)

Since he is not getting paid for two week we do 52 - 2 = 50 week of work.

Since per week salary is $1224 we multiply by 2 for two weeks = $2448

Before $63,648 - $2448 = $61200 per year (Now he's making $61200/year)

Answer:

A. 15

Step-by-step explanation:

The segment addition postulate states that the lengths of the pieces of a segment will add up to the length of the entire segment.

Using the segment addition postulate, The value of x is 15.

The segment addition postulate states that the lengths of the pieces of a segment will add up to the length of the entire segment.

WE have been given the following parameters;

HI = 6x + 8

DJ = 2x - 4

HJ = 124

Then by using  the segment addition postulate,

HI + DJ + HJ

(6x + 8) +(2x - 4) = 124

8x + 4 = 124

8x = 120

x = 15

(6x + 8)  = 6(15) + 8 = 78

(2x - 4)  = 2(15) -4 = 20

Therefore, the value of x is 15.
