Answer:

504 millimeters (or 50.4 cm)

Step-by-step explanation:

   Width of key in student calculator = 14 millimeter (1.4 cm)

   Width of key in demonstration calculator = 2.8 cm

Thus, the demonstration calculator's dimensions are twice that of students' (in cm)

Also given, student calculator height as 252 millimeters (25.2 cm)

Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)

If the manufacturer gains 6 %, the wholesale dealer 8% and the retailer 10 %. Then what
Alexandra [31]

Answer:

The production cost is Rs 12,500

Step-by-step explanation:

Let the production cost be $x

At any point in time

sales price = cost price +( profit percentage* cost price)

Manufacturer gaining 6%

That would be;

x + 6% of x

x + 0.06x

= 1.06x

Wholesaler gaining 8%

= 1.06x + 8% of 1.06x

1.06x + 0.08(1.06x)

= 1.06x + 0.0848x

= 1.1448x

The for the retailer

= 1.1448x + 10% of 1.1448x

= 1.1448x + 0.11448x

= 1.25928x

1.25928x = 15,741

x = 15,741/1.25928

x = 12,500

Can someone help me
kramer

Answer:

m∠W = 134

Step-by-step explanation:

JGN is congruent to AIW and the names of the triangles are both in the same order. That may sound confusing but this means that:

J = A

G = I

N = W

So, if angle N is 134 then angle W is the same.

Please help me with this I don’t understand it what do ever
dmitriy555 [2]

Answer:

x=3

y=4/3

Step-by-step explanation:

Substitution Method:

Substitute the value of x into the equation

2(6y-5)-3y=2

Solve for y

12y - 10 - 3y= 2

12y - 3y=2 +10

9y=12

y=12/9

y=4/3

Substitute the value of y into the other equation

x=6×(4/3) - 5

Solve for x

x=8-5

x=3
