Answer:
13.5 mg
Step-by-step explanation:
Here given Cobalt isotope has half life of 5.3 years.
Initial amount is 50 mg.
Given time(10 years) is roughly equals to two half life.
So, after 5.3 year 25 mg of isotope will left further in next half life only around 12.5 mg remains.
Among options 13.5 mg is the best possible
Hello there.
<span>Ariel travels 400 miles in 8 hours. What is her rate of change or rate?
</span>Rate of change is defined as
change in distance
<span>change in time
400 </span>÷ 8 = 50
Answer: <span>B) 50 miles per hour
</span>
5 hours.
Divide the numbers.
$125 divded by $25 = 5
Answer: Kim can afford 5 hours lf repair time. (Brainlest?)
Have a good rest of your day/night!!
Answer:
7 feet
Step-by-step explanation:
56/8 = 7
i'm assuming by breadth you mean width
Given:
length = 6
width = 5
height = 9
Diagonal of a rectangular prism = √(l² + w² + h²)
d = √ 6² + 5² + 9²
d = √ 36 + 25 + 81
d = √ 142
d = 11.916 ROUNDED TO NEAREST WHOLE UNIT D. 12 CM.
Given:
Pyramid base = 12 cm
height = 8 cm
We can use the Pythagorean theorem to look for the slant height because it is the hypotenuse of a right triangle.
a² + b² = c²
a is the height ; b is the base ; c is the slant height.
b = 1/2 of the pyramid base.
b = 12/2 = 6 cm
8² + 6² = c²
64 + 36 = c²
100 = c²
√100 = √c²
10 = c Answer is letted D. 10 cm.
