Baseball hat is on sale for 15% off, which is $2.70. How much does the baseball hat cost at full price?

lidiya [134]

Answer:

27.9 dollars

Step-by-step explanation:

2.70= 15 percent

2.70x2=5.4=30 percent

5.4+2.70=8.1=45 percent

8.1x2=16.2=95 percent

95 percent + 15 percent=18.9

18.9=105 percent

in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3

which = .9

18.9+9=27.9

100 percent is 27.9 dollars

Answer:

Radius of the given circle is r = 2.

Step-by-step explanation:

Given equation of the circle is $x^2 + y^2 = 4$ .

To find that let's compare with the formula of the circle with is $x^2 + y^2 = r^2$ , where r is the radius.

We get $r^2 = 4$

take square root of both sides.

$r=2$

Hence radius of the given circle is r = 2.
