Answer:

2.28 x 10^10

Step-by-step explanation:

(3.8 x 10^6) (6 x 10^3) do distributive property 3.8 to 6 and 10^6 to 10^3

22.8 x 10^9 since its 22.8 you have to make it in "once" place, therefore, move the decimal to the left and add the exponent "1"

2.28 x 10^10 is the answer

Sams brother is 7 years older than Sam. His mother is 4 less than 3 times sams age. Their combined age is 63. How old isn’t Sam,

statuscvo [17]

The answer is 14. This is because 63=3+x+3x-4. Then You just subtract it and then you get 64=4x. Then you just divide it and then you get x=16.

Can a right triangle have a leg that is 10 meters long and a hypotenuse that is 10 meters long

pishuonlain [190]

Lets see
a and b are legs
c=hypotnuse
a^2+b^2=c^2
10^2+b^2=10^2
100+b^2=100
minus 100 both sides
b^2=0
b=0
false, if you have a leg legnth 0, then they lines are right on top of each other

Answer: A=351.68 cm²

Step-by-step explanation:

To find the area of the shaded region, we would subtract the area of the circle by the area of the inner circle.

Area of Circle

$A=\pi r^2$

$A=\pi (11)^2$

$A=121\pi$

Area of inner (white) circle

$A=\pi r^2$

$A=\pi (3)^2$

$A=9\pi$

Now that we have the area to the circle and inner circle, we would subtract to find the area of the shaded region.

$A=121\pi -9\pi$

$A=112\pi$

$A=351.68 cm^2$
