The Surface Area of the sphere is 1017.16 unit^2.

what is the surface area of the sphere?

The surface area of the sphere is 4*pi*r^2.

where, r is the radius

Calculation :

given radius is 9 units

putting value in the formula of the sphere

S(area)=4*pi*r^2

=4*3.14*9^2

=4*3.14*81

=1017.16 UNIT^2

The Surface Area of the sphere is 1017.16 unit^2.

Xy=-2
x+y=6

minnus x from second equation
y=6-x
sub for y
x(6-x)=-2
6x-x^2=-2
add x^2 both sides and minus 6x both sides
0=x^2-6x-2
use quadatic formula

if you have
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

x^2-6x-2=0
a=1
b=-6
c=-2
x= $\frac{-(-6)+/- \sqrt{(-6)^{2}-4(1)(-2)} }{2(1)}$
x= $\frac{6+/- \sqrt{36+8} }{2}$
x= $\frac{6+/- \sqrt{44} }{2}$
x= $\frac{6+/- 2\sqrt{11} }{2}$
x= $3+/- \sqrt{11}$

x= $3+ \sqrt{11}$ or x= $3- \sqrt{11}$
aprox
x=6.31662 or -0.316625

those are the numbers

6.31662 and -0.316625

20 is what percent of 52? Round your answer to the nearest tenth.

Schach [20]

20/52 = b/100
20 x 100/52 x b
2000/ 52b
b = 38.5

Explanation:

b is a variable that stands for the unknown quantity
Write 20/52 as equal to b/100
Next we cross multiply 20 by 100 = 2000 and 52 by b = 52b
2000/52b is equal to 38.46 but roundest to the nearest tenth it is 38.5

Caitlyn has a credit card with a spending limit of $1500 and an APR (annual percentage rate) of 18%. During the first month, Cai

anzhelika [568]

APR=18%
Monthly interest = 18/12=1.5%
If Caitlyn paid before due date,
amount liable for interest charges = 375-250 = $125
Interest charge for the month
=$125*1.5%
=$1.88

If a single expression is required, then
interest = (375-250)*0.018/12 = $1.88 to the nearest cent.
