Answer:
0.25 % loss.
Step-by-step explanation:
Let the cost of 1 watch be rs x then the cost of the other is rs 400 - x.
Let the sp be rs y.
So we have:
y = x + 0.05x
y = (400 - x) - 0.05(400 - x)
y = 400 - x - 20 + 0.05x
y = 380 - 0.95x
So x + 0.05x = 380 - 0.95x
2x = 380
x = 190.
and y = 190 + 0.05*190 = 199.5.
So the total selling price = 2 * 199.5 = rs 399
So final loss is [ (400-399)/ 400] * 100
= 0.25 %.
Answer:
A) y = 4/3 x - 1/3
Step-by-step explanation:
(4,5) and (-2,-3)
Slope = (5 + 3)/(4 + 2)
= 8/6
= 4/3
Equation
y + 3 = 4/3(x + 2)
y + 3 = 4/3 x + 8/3
y = 4/3 x + 8/3 - 9/3
y = 4/3 x - 1/3
Answer:
y = 4/3 x - 1/3
Answer:
I think it's A AND C. The diameter is just the radius multiplied by 2 at the end of the day.B is just wrong.
Answer:
4m is the answer.
Step-by-step explanation:
a = 3m
b = ?
c = 5m
According to the Pythagoras theorem,
a² + b² = c²
3² + b² = 5²
9 + b² = 25
b² = 25 - 9
b² = 16
b = 4m
∴ The distance between the ladder and the bottom of the slide is 4m.
Solution
For this case we can take square root in both sides and we have:
![3x-5=\pm\sqrt[]{19}](https://tex.z-dn.net/?f=3x-5%3D%5Cpm%5Csqrt%5B%5D%7B19%7D)
And solving for x we got:
![x=\frac{5\pm\sqrt[]{19}}{3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%5Cpm%5Csqrt%5B%5D%7B19%7D%7D%7B3%7D)
then the solutions for this case are:
B and E
