If D varies directly with t and D is 105 when t is 3 then value of D when t is 8 is equal to 280
<u>Solution:</u>
In this sum we have been given that there is a direct relationship between d and t.
If d is 105 when t is 3 so now, we need to find d when t is 8.
To do this we can simply use the unitary method. The definition of unitary method is, the unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, according to the definition we need to find the value of d when t is 1.
This can be done as follows:

Therefore, the value of d when t = 1 is 35.
Now, if the value of t=8 then d becomes:

Hence, when t=8 the value of d is 280.

Answer:
[ 4, ∞ )
Step-by-step explanation:
Given
8(x - 5) - 3x ≥ - 20 ← distribute and simplify left side
8x - 40 - 3x ≥ - 20
5x - 40 ≥ - 20 ( add 40 to both sides )
5x ≥ 20 ( divide both sides by 5 )
x ≥ 4
Solution set is [ 4, ∞ )
