The length of x is 3. Since the two trapezoids are similar. In the second trapezoid the top is half of 10. so it would be logical for x to be 3
Answer:
the third one
Step-by-step explanation:
9 to the power of 4 is 9 multiplied by it's self 4 times
Answer:
$0.29
Step-by-step explanation:
Multiply the unit weight ($0.24/ounce) by the weight (1.2 oz.):
$0.24 1.2 oz
.24 * 1.2 = $0.288
So, the rounded answer will be $0.29
The mass of radioactive material remaining after 50 years would be 48.79 kilograms
<h3>How to determine the amount</h3>
It is important to note that half - life is the time it takes for the amount of a substance to reduce by half its original size.
Given the radioactive decay formula as
m(t)=120e−0.018t
Where
t= 50 years
m(t) is the remaining amount
Substitute the value of t


Find the exponential value
m(t) = 48.788399
m(t) = 48.79 kilograms to 2 decimal places
Thus, the mass of radioactive material remaining after 50 years would be 48.79 kilograms

Answer:
39.407m
Step-by-step explanation:
sin 66deg = 36/length of cable
length of cable = 36/sin 66deg = 39.407m (5sf)
