An airplane files with a constant speed of 680 km/h. How far can it travel in 2 1/4 hours?

1 answer:

6 0

$\frac{distance}{hour} =\frac{680km}{1 hour} = \frac{x}{2\frac{1}{4}}\\
\frac{680}{1} = \frac{x}{2\frac{1}{4}}\\
680*2\frac{1}{4}=1*x\\
1530=x$

The plane can travel 1530km in $2 \frac{1}{4}$ hours.

8(3 – 2x)+ 4(3x – 2)=-16 Can someone solve for x? please

castortr0y [4]

Answer: x = 8

Step-by-step explanation:

8(3-2x) + 4(3x - 2) = -16

expanding the equation , we have

24 - 16x +12x - 8 = -16

16 - 4x = -16

collecting the like terms

4x = 32

x = 32/4

x = 8

Quinn has 6 bottles of water that each weigh \large \frac{3}{5} pound. What is the total weight of the water bottles?_

Art [367]

Answer:

3.6 pounds

Step-by-step explanation:

If 1 bottle weighs 3/5 pounds

the 6 bottles will weigh 6 x 3/5

= 18/5

ratio method :

1:3/5

6:x

since the ratios are direct we can cross multiply

18/5 = 1x

so the 6 bottles weigh 18/5 pounds or 3.6 pounds

Answer:

$(x-230)^2+(y-220)^2=6100$

Step-by-step explanation:

The equation for a circle is $(x-h)^2+(y-k)^2=r^2$ , where $(h,k)$ is the vertex of the circle and $r$ is the radius. Immediately, since the center of the circle is given, we know what $h$ and $k$ are. $h$ is 230 and $k$ is 220.

The only thing we need to find is the radius, which will just be the distance from the center (230,220) to a point on the circumference (170,170). The distance between them can be calculated using the distance formula, which is really just the Pythagorean Theorem rearranged. The formula states that $d=\sqrt{x^2+y^2}$ , where $x$ is the change in the x-coordinates of the two points and $y$ is the change in the y-coordinates of the two points. Plug-in $x$ for 60 and $y$ for 50 to get $d=\sqrt{50^2+60^2}$ . Solve for $d$ , arriving at $\sqrt{6100}$ . Therefore, the radius of the circle is $\sqrt{6100}$ .

Finally, we have all of the components to create the equation of the circle. Plug-in 230 for $h$ , 220 for $k$ , and $\sqrt{6100}$ for $r$ .

The equation of the circle will be $(x-230)^2+(y-220)^2=6100$ .

Hope this helps :)
