They would have to split apart the group with 6 blueberries. Each friend would get three blueberries from this group.
Answer:
The percentage rate is 4.5%.
Step-by-step explanation:
The given formula for simple interest is I=prt where I=simple interest, p=principle, r = percentage rate and t=time. In the problem, we are told that after six years (t=6), $7000 (p=7000) earns $1890 (I=1890). We can then substitute in the values for three of our variable to get the following: 1890 = (7000)(6)r. Multiplying 7000x6 = 42000 giving us 1890 = 42000r. Using inverse operations, we divide both sides of the equation by 42000 to get 0.045 = r. Since r = percentage rate, we need to multiply our decimal by 100 to find the percentage. 0.045 x 100 = 4.5%.
I think it is D

2. The table below shows that the distance d varies directly as the time t. Find the constant of variation and the equation which describes the relation.
<h2><u>Solution</u>:-</h2>
Since the distance d varies directly as the time t, then d = kt.
Using one of the pairs of values, (2, 20), from the table, substitute the values of d and t in d = kt and solve for k.
![\sf{\rightarrow{d = kt}}](https://tex.z-dn.net/?f=%5Csf%7B%5Crightarrow%7Bd%20%3D%20%20kt%7D%7D)
![\sf\rightarrow{20 = 2k }](https://tex.z-dn.net/?f=%20%5Csf%5Crightarrow%7B20%20%20%3D%202k%20%7D)
![\sf\rightarrow{K= \frac{20}{2} }](https://tex.z-dn.net/?f=%20%5Csf%5Crightarrow%7BK%3D%20%5Cfrac%7B20%7D%7B2%7D%20%7D)
![\sf\rightarrow{K={\color{magenta}{10}}}](https://tex.z-dn.net/?f=%5Csf%5Crightarrow%7BK%3D%7B%5Ccolor%7Bmagenta%7D%7B10%7D%7D%7D)
<h2><u>Answer</u>:-</h2>
- Therefore, the constant of variation is 10.
42
let the smallest even number be x, than the four even numbers are x, x+2, x+4, x+6, their sum is 180
x+x+2+x+4+x+6=180
4x+12=180
4x=168
x=42
the smallest even number is 42.
