Answer:

17.5

Step-by-step explanation:

8 : 10 = 14 : x

8x = 10*14 = 140

x = 140/8 = 17.5 cm

Anettt [7]

If you unroll the fence, you find it has a length equal to the circumference of a circle of radius 10 m and an average height of 3 m. Its two-sided area will be

... A = 2·(3 m)·(2π·(10 m)) = 120π m²

Then the amount of paint required is

... (120π m²) × (1L)/(100 m²) = 1.2π L ≈ 3.77 L

Suppose that when you factor 4t^6-r^10, you get (2t^x+r^y)(2t^x-r^y). determine the sum of t and r.

Alexxandr [17]

Answer:

Step-by-step explanation:

Given the expression

4t^6-r^10 we are to factorize in the form;

(2t^x+r^y)(2t^x-r^y)

First we need to factorize (2t^x+r^y)(2t^x-r^y)

$= (2t^x+r^y)(2t^x-r^y)\\= 4t^{2x}-2t^xr^y + 2t^xr^y - r^{2y}\\= 4t^{2x}-r^{2y}$

Compare $4t^{2x}-r^{2y} \ with \ 4t^6-r^{10}$

$4t^{2x} = 4t^6\\t^{2x} = t^6\\equate \ the \ powers\\2x = 6\\x = 3\\$

Get y;

$r^{2y} = r^{10}\\2y = 10\\y = 5\\Hence \ x + y = 3+5 = 8$

Hence the sum of x and y is 8

Keiko, Dale, and Jose have a total of $107 in their wallets. Jose has 3 times what Dale has. Keiko has $8 less than Dale. How mu

olga2289 [7]

Answer:

Amount in Dale's wallet :$23

Amount in Keiko's wallet :$15

Amount in Jose's wallet: $69

Step-by-step explanation:

Let the money in Dale's wallet be $X

Given Jose has 3 times money than what Dale has.

if Dale has $X then Jose has $3X.

Also Keiko has $8 less than Dale

if Dale has $X then Keiko has $X - $8

Also Keiko, Dale, and Jose have a total of $107 in their wallets.

Writing this in form of mathematical expression with their value of money in terms of X we have given below equation.

$X + $3X + $X - $8 = $107

=> $5X - $8 = $107

=> $5X = $107 + $8 = $115

=> X = $115/5 = $23.

Amount in Dale's wallet = $X = $23

Amount in Keiko's wallet = $X - $8 = $23 - $8 =$15

Amount in Jose's wallet = $3X = $3*23 = $69
