Yuri purchased 8 trees to have planted at his house. the store charged a delivery fee of $5 per tree.

the total cost of the trees including the delivery was $168.

how much did each tree cost?

$16.

Step-by-step explanation:

Let t represent the cost of each tree.

We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.

We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be

The total cost of purchasing 8 trees will be .  

Since the total cost of the trees including the delivery was $168, so we can get an equation as:

Upon dividing both sides of our given equation by 8, we will get:

Therefore, the cost of each tree is $16.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
