Answer:
13 pounds of grass.
Step-by-step explanation:
You need 20 pounds of grass seed to plant inside the baseball diamond.
The Baseball Diamond is a square of side = 90 ft
The Softball Diamond is a square of side = 60 ft
The ratio of the size of the Baseball Diamond to that of Softball Diamond is:
90: 60 = 3:2
If 3 represents 20 pounds, then 2 represents;
× 20 = 13.33333333 pounds = 13 pounds (rounded to nearest pound)
Cost per ticket for the rides = $1.50.
a) Let us assume the number of ride tickets = x.
Total cost of x number of rides = y.
Total amount spent = $48.75.
Amount spent on 20 tickets = 20 × 1.50 = $30
<em>Fair admission charge = Total amount spent - Amount spent on 20 tickets</em>
<em> = $48.75 - $30 = $18.75.</em>
Let us apply slope-intercept form y=mx+b to get the equation.
Total cost of x number of tickets at the rate $1.50 each ticket = 1.50x.
To<em>tal cost of fair = Total cost of x number of tickets + Fair admission charge.</em>
<h3>b) y = 1.50x + 18.75.</h3>
R² - 6r - 8 = 0
r² = 7.12
r = -1.12
Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%
Hello!
The recursive rule for an arithmetic sequence: 
.
The explicit rule for an arithmetic sequence: 
.
is the value you are trying to find, or simply the answer. :)
is the common difference of the sequence.
is the first term of the sequence.
Given, 
and 
...
The common difference is -6, and the first term is 8.
Plug these values into the explicit rule for an arithmetic sequence, you get:
.
Therefore, the answer is A, 
.
If you wondered why, is equal to , the Commutative Property of Multiplication states that when two numbers are multiplied together, the answer is the same regardless of the order of the numbers, which makes and equal to each other.
