Hello I hope I can help you with this!!

EXPLANATION:
first we work out what all the marbles equal which is 9/9=63

Then we work out what 1/9 of the marbles are! Which is 1/9= 7 marbles!!

Then we work out what 5/9 of them are! Which is 5/9= 35 marbles

Then now we work out 4/9 which is our RED marbles! We do 4 times 7 which equals 28 red marbles!!

if you want to check to add the two numbers and they equal 63!

ANSWER= 28 red marbles

hoa [83]

Answer:

<em>El camión lleva 3000 cajas de patatas</em>

Step-by-step explanation:

<u>Proporciones</u>

La capacidad de carga de un camión es de 68.25 Toneladas de patatas.

Como 1 tonelada es equivalente a 1000 Kg, expresamos la capacidad en Kg:

68.25 * 1000 = 68250 Kg

Cada caja de patatas pesa 22.75 Kg, luego el número de cajas que caben en el camión son:

68250/22.75 = 3000 cajas

El camión lleva 3000 cajas de patatas

A rectangular pool is to be built on a lot that measures 20 m by 12 m. A wooden deck of uniform width, equal to the area of the

frutty [35]

The length and breadth(width) of the pool are

$l\approx15.7m\text{ and }b\approx7.7m$

Let

$l=\text{length of the side of the pool}\\b=\text{breadth of the pool side}\\w=\text{the width of the strip of deck surrounding the pool}$

From the question, we can build the following relationships

$l+2w=20\\b+2w=12$

subtracting to eliminate $w$ (we do not even need it!)

$l-b=8\\b=l-8$

we can also build another relationship from the question. Since the area of the strip equals the area of the pool:

$lb+lb=2lb=20\times 12\\lb=120$

We have two unknowns, $l$ and $b$ . Eliminate $b$

$lb=120\\l(l-8)=120\\l^2-8l-120=0$

If we solve the quadratic equation for $l$ , we get

$l=4+2\sqrt{34}\approx 15.7m$

and

$b=l-8\\b=(4+2\sqrt{34})-8\\b=2\sqrt{34}-4\approx7.7m$

The length and breadth(width) of the pool are

$l\approx15.7m\text{ and }b\approx7.7m$

Please answer quick!!

IRINA_888 [86]

Answer:

mBC = 96°

mB = 55°

mC = 77°

mAB = 154°

Step-by-step explanation:

The angle mB inscribes the arc mAC, so we have:

$mB = mAC / 2$

$mB = 110 / 2 = 55\°$

The sum of internal angles of a triangle is 180°, so in the triangle ABC we have:

$mA + mB + mC = 180$

$48 + 55 + mC = 180$

$mC = 180 - 48 - 55$

$mC = 77\°$

Using again the property of inscribed angles, we have:

$mAB = 2*mC = 154\°$

$mBC = 2*mA = 96\°$
