zmey [24]

Answer:

3 pencils

Step-by-step explanation:

We are given Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.

Number of pencils=72

Number of calculators=24

If Zayed creates the greatest number of identical packages

Then , we find GCF of 72 and 24

$72=2\times 2\times 2\times 3\times 3$

$24=2\times 2\times 2\times 3$

GCF= $2\times 2\times 2\times 3$

Hence, Zayed creates 24 packages.

Number of pencils in each package= $\frac{72}{24}=3$

Hence, 3 pencils and one calculator will be in each package .

GarryVolchara [31]

Answer:

9 basket balls, 15 foot balls

Step-by-step explanation:

Let x be the number of basket ball

y be the number of foot ball

1 basket ball = $22

so x basket ball = 22x

1 foot ball = $30

so y foot ball = 30y

Total cost = 648

The equation becomes 22x+ 30y = 648

Given : They bought 6 more footballs than basketballs.

foot ball (y) = 6 more basket balls(x)

so y = x + 6

we solve for x and y

Now we plug in x+6 for y in the equation 22x+ 30y = 648

22x+ 30(x+6) = 648

22x + 30x + 180 = 648

Subtract 180 on both sides

52x = 468

Divide both sides by 52

so x= 9

Number of basket ball x= 9

Number of foot ball y=x+6= 9+ 6 = 15

A pile of gravel is in the shape of a cone. The radius of the pile of gravel is 9 feet at the base. The height of the pile of gr

vitfil [10]

Answer:

678.24 cubic feet.

Step-by-step explanation:

A pile of gravel is in the shape of a cone.

Radius of base of cone (r) = 9 feet

Height of the cone (h) = 8 feet

Volume of the cone (V) = ?

We know that, volume of a conical shape of radius 'r' and height 'h' is given as:

$V=\frac{1}{3}\pi r^2h$

Now, plug in the given values and use 3.14 for π. Solve for 'V'. This gives,

$V=\frac{1}{3}\times 3.14\times 9^2\times 8\\\\V=\frac{3.14\times 81\times 8}{3}\\\\V=3.14\times 27\times 8\\\\V=678.24\ ft^3$

Therefore, the volume of the gravel of pile is 678.24 cubic feet.
