12.5+12.5+5.5+5.5=36 there are 3 ft in a yard so 36*3=108ft
L+L+W+W= Area
10x6=60 pounds
36x12=432 ounces which is 27 pounds
60+27=87
$22.50
20 pounds -12.00
50 pounds-.50
30 pounds since there is 17 pounds left -10
$22.50 in total
Hope this is what you needed
Answer:
x = √2/2
Step-by-step explanation:
Use the identity:
arcsin x + arccos x = π/2
Therefore, we can rewrite this as:
arcsin x (π/2 − arcsin x) = π²/16
If we substitute y = arcsin x:
y (π/2 − y) = π²/16
π/2 y − y² = π²/16
0 = y² − π/2 y + π²/16
0 = 16y² − 8π y + π²
0 = (4y − π)²
y = π/4
Substituting back:
arcsin x = π/4
x = sin(π/4)
x = √2/2
Answer:
equation for a straight horizontal line passing through the coordinates (3,4):
y=4
Step-by-step explanation:
Answer:
X=3.5
Step-by-step explanation:
AD = 4+3 = 7
ED = X
that is the ADE triangle
AB= 4
CB = 2
this is the ABC triangle
because the A angle shares the same triangles
ED /CB = AD/ AB
X/2 = 7/4
by multiplying all of the equation by 2 to get rid of the 2 under the x
X= 7/2 which is 3.5
so X= 3.5
