Answer:
24 mm
Step-by-step explanation:
Since it is a right triangle, we can use Pythagorean theorem
where a and b are the legs, and c is the hypotenuse.
We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.
Solve the exponents
Now, solve for b. To do this, get b by itself.
First, subtract 100 from both sides
Take the square root of both sides
b=24
So, the other leg is 24 mm
Answer:
The final cost price of the cellphone is $121.5
Step-by-step explanation:
The marked price of the cell phone = $150
Now, sale percentage on the marked price = 10%
Now, 10 % of 150 =
⇒The sale discount on the marked price = $15
So, the selling price of cellphone = Marked Price - Sale discount
= $150 - $15 = $135
Now, the second discount offered on $135 is 10%
10 % of 130 =
⇒The additional sale discount on the selling price = $13.5
So, the final cost of cellphone = Selling Price - Additional Sale discount
= $135 - $13.5 = $121.5
Hence, the final cost price of the cellphone is $121.5
