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:
Option D
Step-by-step explanation:
I evaluated the numbers in the parentheses and multiply both of them. Then I found the answer that is equivalent to mine. I got 7/10, which is also equal to 7.0 x 10^-1.
Hope this helps! :)

Answer:
199.5 ft^3
Step-by-step explanation:
to find your answer you simply multiply all the measurements together
19 * 1.5 * 7 is your equation
19 * 1.5 * 7 = 199.5
it is 199.5 ft^3
