Answer:

The original price is $6,95

Step-by-step explanation:

Jaylynn bought a mascara on sale  for $5.56. This price has a 20% discount,  so  $5.56 is the 80% of the original price.

We are looking for the original price, that is 100%  

We use cross-multiplication

a/b=c/d

$5.56/80%= x/100%

x=$5.56*100%/80%

x=$6.95

The answer is $6.67 because if you multiply $5.56 by 20% you get 6.672 but you would have to round it to the nearest cent.

The circumference of an NBA-approved basketball is 29.6 in. Given that the radius of Earth is about 6400 km, how many basketball
ella [17]

Answer:

167,886,383 basketballs

Step-by-step explanation:

We are asked to find how many basketballs would take to circle around the equator. We have given the earth's radius. So, we need the formula to obtain it's perimeter. Thus:

Perimeter = Pi*diameter [m]\\Where Pi = 3.14

Earth's diameter is simply radius*2. It means:

P= 3.14*6400*2 = 40,192 [km]

On the other hand, we have a basketball crcumference; however, we need to obtain its diameter so that we can later calculate how many basketballs fit on earth's equator by simply dividing earth's circumference by a basketball's diameter.

Diameter of a basketball:

D= Perimeter /Pi [m]

We need to change units to fit in the international system.

29.6 in to cm = 29.6*2.54 = 75.184 [cm]

Then:

Diameter=75.184/3.14 = 23.94 [cm]

We have to convert earth's perimeter in km to cm:

Equator=40192[km]*100000=4,019,200,000 [cm]

Finally, dividing total earth's circumference by a basketball diameter:

Totalbasketballs=4,019,200,000/23.94= 167,886,383 [basketballs]

If 4b-3=2b, then 12b=
Andru [333]
Hi there! The answer is 18.

First we need to solve the first equation for b.
4b - 3 = 2b

Subtract 2b from both sides.
2b - 3 = 0

Add 3 to both sides.
2b = 3

Divide both sides by 2.
b = \frac{3}{2} = 1 \frac{1}{2}

Now we can plug our value of b into the second expression.
12b = 12 \times 1 \frac{1}{2} = 18
