Answer:
Last option (bottom right)
Step-by-step explanation:
The scientific notation for 0.002 is (you move the decimal 3 to the right to get 2)
multiply the number of mustard seeds with this and you get 80. In scientific notation it is (move the decimal 1 to the left to get 8.0)
Answer:
One of the sides is 6 cm and the other is 8 cm
Step-by-step explanation:
Let's call the unknown sides a and b. From the perimeter information (24 cm) we have:
a + b + hypotenuse = 24
a + b + 10 = 24
a + b = 14
b = 14 - a
So now we can right the Pythagorean theorem as follows:
and from this expression in factor form to be zero a must be 6 or a must be 8.
Therefore the solutions are a = 6 (and therefore b = 14 - 6 = 8)
or a = 8 (and therefore b = 14 - 8 = 6)
