Answer:
134 sneakers and 66 sandals
Step-by-step explanation:
Sneakers= x, sandals= y
Profit rate:
- sneakers: (10-2)/8= 25%
- sandals: (17-14)/14= 21.4%
Sneakers are more profitable, so it should be maximized.
Cost:
8x+14y≤2000
x+y≤200
if we assume the maximum of 200 shoes stocked, then:
x= 200-y
8(200-y)+14y ≤ 2000
1600 - 8y +14y ≤ 2000
6y≤400
y≤66 and x=134 is the best option
Answer:
x = 
Step-by-step explanation:
This question is from the topic subject of formula. It implies expressing x in terms of G, H y and J.
Given that: Gx + Hy = J
Subtract Hy from both sides to have;
Gx + Hy - Hy = J - Hy
⇒ Gx = J - Hy
Then divide both sides by G, so that we have;
x = 
Therefore,
x = 
The angle measured is 1.72 radians
<em><u>Solution:</u></em>
Given that radius is 9 units and arc length is 15.5 units
To find: angle,
, in radians
<em><u>The length of arc when angle in radians is given as:</u></em>

Where, "r" is the radius and "s" is the arc length
is central angle measured in radians
Substituting r = 9 and s = 15.5 in above formula,

Thus the angle measured is 1.72 radians
