Find the solution to the system of equations.

Ow many cans of paint are needed to cover an area of 2,200 square units if one can of paint covers an area of 400 square units?

salantis [7]

The number of cans needed to paint an area covering 2,200 sq. units will be given by:
number of cans=[area required to be painted]/[area that 1 can of paint can cover]
=2200/400
=5.5
Therefore we conclude that we will need 5.5 cans of paint

A circle is centered at $O$ and has an area of $48 \pi.$ Let $Q$ and $R$ be points on the circle, and let $P$ be the circumcente

nikklg [1K]

Answer:

Area of Triangle QRP = 3 $\sqrt{3}$

Step-by-step explanation:

According to Question , We have a circle With Centre 'O' & Area 48 $\pi$ .

Area Of Circle = 48 $\pi$

$\pi$ $r^{2}$ = 48 $\pi$

r = $\sqrt{48}$

Now We Have Two Points Given On Circle Q & R , P Is Circumcentre Of Triangle QRO .

Thus A Circle Can Also Be Formed with Centre P . ( See attachment For Diagram )

Now The Diameter of Circle With Centre P = Radius Of Circle with Centre O

so Radius Of Circle With Centre P( $r_{2}$ ) = $\frac{\sqrt{48}}{2}$

Now We Have To Find Area Of Equilateral Triangle .

A = $\frac{\sqrt{3}}{4} r_{2} ^{2}$

A= $\frac{\sqrt{3} }{4} * \frac{\sqrt{48} }{2}*\frac{\sqrt{48} }{2}$

The Area Of PQR is = 3 $\sqrt{3}$

At a particular restaurant, each onion ring has 65 calories and each slider has 250 calories. A combination meal with onion ring

andre [41]

Answer:

The number of onion rings is 3 in the combination meal and the number of sliders is 2 in the combination meal.

Step-by-step explanation:

Given:

At a particular restaurant, each onion ring has 65 calories and each slider has 250 calories. A combination meal with onion rings and sliders has a total of 5 onion rings and sliders altogether and contains 695 calories.

Now, to find the number of onion rings in the combination meal and the number of sliders in the combination meal.

Let the number of onion rings in the combination meal be $x.$
