Answer:

pounds

Step-by-step explanation:

10³ = 10(10)(10) = 1000

4.5(1000) = 4500

4500 grams would be much too small for a car.

4500 tons would be 4500(2000) = 9000000 pounds; this would be much too large for a car.

4500 ounces would be much too small for a car.

4500 pounds, however, is about the right size for a car.

Scilla [17]

Answer:

$35.50

Step-by-step explanation:

55.50-48= 7.5

2008-2005 = 3

7.5 divided by 3 = 2.5 per year

2005-2000 = 5 multipled by 2.5 = 12.5

48-12.5=35.5

4 1/2 ÷ 1 1/4 = a b/c

Alex17521 [72]

Here is the equation:

$4 \frac{1}{2} \div 1 \frac{1}{4} = a \frac{b}{c}$

When you're going to be dividing fractions, you have to keep, change, and flip. Also, make sure you make the fractions improper when it's a mixed number.

$4 \frac{1}{2} = \frac{9}{2}$

$1 \frac{1}{4} = \frac{5}{4}$

Now keep, change, flip

$Keep\ \frac{9}{2} \\ Change \div to\ \times \\ Flip\ \frac{5}{4} = \frac{4}{5}$

Your new equation is:

$\frac{9}{2} \times \frac{4}{5}$

Multiply:

$\frac{9}{2} \times \frac{4}{5} = \frac{36}{10} = 3 \frac{6}{10} \rightarrow 3 \frac{3}{5}$

Your answer is:

$3 \frac{3}{5} \\ a = 3 \\ b = 3 \\ c = 5$

Please please plz plz plz plz plz plz plz plz plz please please help me plz

To solve for these, we will use formulas and convertions as we go.
For 1:
We are looking for kg (kilograms) to g (grams). 1 g = 0.001 kg.
We have 2.5 kg. This means we must multiply 2.5 by 1,000.
2.5 x 1,000 = 2,500.
1.) is 2,500 grams.
For 2:
This problem has multiple steps, but we will successfully solve it. As of now, we have yards. There are 3 feet in a yard, and 12 inches in 1 ft. We will convert yards to feet, and then feet to inches.
500x3 = 1500, 1500 x 12 = 18,000.
2.) is 18,000 inches.
For 3:
There are 2,000 pounds in 1 ton. Using this, we can determine how many tons we have.
7,000/2,000 = 3.5
3.) is 3.5 tons.
I hope this helps!
