Write an expression for the missing value in
2 answers:
Answer:
C) a+3
Step-by-step explanation:
We are given the following data:
Tom's Age: 10 11 12 a
Kim's Age: 13 14 15
We have to evaluate Kim's age when Tom's age is a.
We have to build a relationship between Tim's age and Kim's age. If we look at their ages carefully we can see a pattern and their relation can be described as:
Thus, when Tim's age is a, we can compute Kim's age as:

Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given
Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in
Divide both sides by -16
Split
or
Solve for t
or
But time (t) can not be negative.
So:
Hence, the diver will hit the water at 1.5 seconds
The volume of the pyramid is
Explanation:
It is given that the base of the pyramid is a right triangle.
The formula to determine the volume of the pyramid is given by
where l is the base length of the pyramid,
w is the base width of the pyramid and
h is the height of the pyramid.
From the figure, we can see that,
,
and
Substituting these values in the formula , we have,
Multiplying the numerator, we get,
Dividing, we get,
Thus, the volume of the pyramid is
