Answer:

361.7cm²

Step-by-step explanation:

Volume of sphere 1= 8cm³

=

Volume of sphere 2 = 647cm³

But volume of sphere = 4/3πr³

The radius of sphere 2

647 = 4/3πr³

((3*647)/4)/π= r³

5.36544 = r

Surface area = 4πr²

Surface area for the big sphere

= 4π5.36544²

= 361.7cm²

Answer:

Hello!

An irrational number is all the real numbers which are not rational numbers.

M = \sqrt{2 is a irrational number.

N = \sqrt{5} is a irrational number.

S = 2 is not irrational, and is actually a whole number.

T = 5 is not irrational, and is actually a whole number.

Have a great day!

I hope this helps! <33

Xavier bought a shirt that was on sale for 20% off the original price. He also used a coupon that gave him an extra 15% off the
just olya [345]
To find the sale price multiply the original cost by the sale percentage. (37x.2= 7.4) subtract this discount from the total (37-7.4= 29.6) this is your sale price. Now multiply this by the other percentage (29.6x.15= 4.44) (29.6-4.44= 25.16) $25.16 is your final answer

Pls help. No files pls. Will give brainliest.

To find f(-20), first figure out which piece x = -20 fits with.

Since -20 < -12, x = -20 first in the domain used by the third piece.

For f(-20), treat this function as if it was just f(x) = 3x-7.

f(-20) = 3(-20) -7

         = -60 - 7

         = -67

Leno4ka [110]

Answer:

y¹⁵-20y¹⁴

Step-by-step explanation:

I'm going to assume that your problem looks like this

(y-20)(y^5)^3

(x^n)^y=x^{n*y}

which means we have

(y-20)*y^{15}\\\\y^{16}-20y^{15}=ya\\\\*y^{15}-20y^{14}=a
