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:
600 ft³
Step-by-step explanation:
Base area: B
Base is triangle
base = 12 ft and height = 5 ft
Area of triangle = B = 
H = 20 ft
Volume = B * H
= 30 * 20
= 600 ft³
A line parallel to y=0 is y=1
In order to figure this out, we need to find the price per ounce of candy. We can do this by dividing the price of the candy by the amount of ounces of candy that were bought.
Tiffany bought 3 ounces and paid 46 cents, so she bought candy with a rate of 46/3 = 15.33 cents per ounce.
Tony bought 13 ounces of candy and paid 76 cents. He bought candy with a rate of 76/13 = 5.85 cents per ounce.
Because Tony is paying less for each ounce, he made the better buy.
Answer:
3, 5.38, 66, V21
Step-by-step explanation:
I assumed that V was the roman numeral V, which is equivalent to the number 5. I then multiplied 5 by 21 which is 105. If this is not the case and they simply wanted us to replace the v with a 5, then the answer would still be correct because 521 is greater than all the numbers in this set. Hope this helps.
