13.36 I don’t know if you need the rounded up form but if so 13.37
Answer:
21 cm
Step-by-step explanation:
Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.
The right triangles formed by the altitude are all similar to the original. That means ...
AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant
Multiplying by AB and substituting the given numbers, we get ...
AD = AB²/AC = 10²/25
AD = 4
Then the segment DC is ...
DC = AC -AD = 25 -4
DC = 21 . . . . . centimeters
Your answer would be 18.39
And here's why:
Behind the decimal your numbers are in the following places.
The (3) is in the tenths place.
The (8) is in the hundredths place.
And the (6) is in the thousandths place.
Whatever number is AFTER the place your rounding, is going to help you out.
If the number is 1-4, you round down.
If the number is 5-9, you round up.
Hope this helps! (:
5 units, it’s the squares that go on that line
Answer:
D
Step-by-step explanation:
Lowest possible price would be when the discount is maximum (i.e 60% and then 25%)
Discount of 60% means the cost is 40% of the original price
40% of 32 = 40/100 × 32 = 12.8
Additional 25% discount means paying 75% of 12.8
75% of 12.8 = 75/100 × 12.8 = 9.6
