First we need to know price per lb. we can calculate that with the info provided. So 10.5/2.5=4.2
So $4.20 per lb.
Double check that work before calculating the rest of the problem: 2.5(4.2)=10.5
So if 1 lb cost $4.20 we can multiply 5 1/4 or in decimal form 5.25(4.2)=22.05
So the total cost for 5 1/4 lbs is $22.05

Please help with the question in the picture!!!

Answer:

We have the measures:

1023 cm

2.3 m

8.72m

6430 mm

1200 mm

6.4 cm

2.5m

0.06km

Now let's write all those measures in the same unit, let's use meters.

We know that:

1cm = 0.01m

1mm = 0.001m

1 km = 1000m

Then, we can rewrie the measures as:

1023 cm = 1023*0.01 m = 10.23 m

2.3 m

8.72m

6430 mm = 6430*0.001 m = 6.430 m

1200mm = 1200*0.001 m = 1.2 m

6.4 cm = 6.4*0.01m = 0.064 m

2.5m

0.06km = 0.06*1000km = 60m

Then the order, from smallest to largest is:

6.4 cm

1200mm

2.3 m

2.5m

6430 mm

8.72m

1023 cm

0.06km

Let the unknown be x

$\sqrt{3} = 27^x$

$3^\frac{1}{2} = 3^{3x}$

Both the base number are 3, so we equate the exponent:

$\dfrac{1}{2} = 3x$

$x = \dfrac{1}{2} \div 3$

$x = \dfrac{1}{2} \times \dfrac{1}{3}$

$x = \dfrac{1}{6}$

Answer: 1/6

The slope should be 3/5 because the rise over run using the points (0,3) and (5,6) result in 3/5.
