Answer:

$4000, $5600 and $7200

Step-by-step explanation:

Let the money be 5x,7x and 9x.

Total collection of money is $16,800

ATQ,

5x+7x+9x=$16,800

21x=$16,800

x=\dfrac{16800}{21}\\\\x=\$800

So, the values are :

5x=5(800) = $4000

7x=7(800) = $5600

9x=9(800) = $7200

Can someone please help me on these two questions tysm
Rashid [163]
Plug them in:

x + 5y = 18 
x - 3y = 10

F. (1,13)
G. (13,1)
H. (-2,4)
J. (-2,-4)

1 + 5*13 = 18 is obliviously not true so that takes out the first option.
 
13 + 5*1 = 18 : This is true but we have to check the next one.
13 - 3*1 = 10 : This is also true so we know this is the answer. We don't really need to check the other 2 but u can if u want to.

Hope that helped :) <span />

If the mass of a material is 44 grams and the volume of the material is 6 cm^3, what would the density of the material be?
Svetlanka [38]

Density is mass per unit volume.

For the given material that has a mass of 44 grams occupying a volume of 6 cm^3, we divide the mass by the volume, i.e.

density of material = 44 grams / 6 cm^3 = 44/6 grams/cm^3 = 7.3 g/cm^3 (to two significant figures)

Someone please help me I only have until January 18th to turn this in. Question: Mr Lopez picks up 2 pallets of dog food to deli
miv72 [106K]

Answer:

Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.

Step-by-step explanation:

Mr Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs 37 1/2 pounds pet bag.

The weight of 1 bag of dog food = 37\frac{1}{2}\text{ pounds }

The weight of 40 bags of dog food = 40 \times 37\frac{1}{2} =1500 \text{ pounds }

Each pallet weighs = 1500 pounds

2 pallets weighs = 1500×2=3000 pounds.

We know that 2000 pounds = 1 ton

\frac{3000}{2000} \text{ pounds}=1.5 \text{ tons}

Hence, Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.
