complementary angles, right angle
we know that
If two angles are <u>complementary angles</u>, then their sum is equal to a <u>right angle</u>
In this problem
-------> by <u>complementary angles</u>
we have

Substitute and solve for Angle TSU

therefore
the answer is the option

Total number of marbles:
75 + 50 + 100 + 25 =
250
Probability of selecting a red marble:
25/250 (since 25 out of 250 marbles are red)
Since the top and bottom of this fraction are both divisible by 25, we can go ahead and divide them both by 25, simplifying to
1/10.
Probability of selecting a green marble:
50/250
Simplifies to 2/10
Simplifies to
1/5.
Probability of selecting a blue or orange marble
(75+100)/250
175/250
Simplifies to
7/10.
To find the probability that each event occurs in order, simply multiply them all together.

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. I will assume the function is:

Required
Determine the rate of decay
In an exponential function
,
The decay rate of the function is calculated as:

By comparison:

So, the equation becomes:

Make r the subject


<em>The rate of decay is 0.14</em>
I think it represents the height hope that helps:)
