Answer:
Let S = price of sweater
Let P = price of pants
S + P = 89.47 because that was the total spent
S = P - 8.53 because the sweater is 8.53 less than pants
Substitute P-8.53 in place of S in the
1st equation and solve for P
P - 8.53 + P = 89.47
2P - 8.53 = 89.47 add 8.53 to both sides
2P = 89.47 + 8.53
2P = 98.00 divide both sides by 2
P = 98.00/2
P = $49.00
S = P - 8.53
S = 49.00-8.53
S = $40.47
A sweater costs $40.47 and the pants cost $49.00
Let the length of unknown side be x
So, hypotenuse = 2x + 1
By pythagorean theorem ie , a² = b² + c²
(2x + 1)² = x² + 15²
4x² + 1 + 4x = x² + 225
3x² + 4x -224
(3x +28)(x-8)
x = -9.33 , 8
Since, length can't be negative
x = 8
∴Unknown side length = 8 m
Length of hypotenuse = 2 x 8 + 1 = 17 m
Hope it helps now.

Answer:
No
Step-by-step explanation:
Scientific notation has to be a number between 1 and 10 times 10 to the something power. 10.2 is not between 1 and 10
<h2>
Density of ethyl alcohol is 56.25 lbm/ft³ </h2>
Step-by-step explanation:
We have 1 lbm = 0.454 kg
1 kg = 2.203 lbm
1 m = 3.28 ft
Density of ethyl alcohol = 9.01 x 10² kg/m³
So
Density of ethyl alcohol = 56.25 lbm/ft³
