For this case, you must use the given expression, taking into account that:
n = number of days.
We have then that for day 21, n = 21.
Substituting we have:
a21 = 100 + (21-1) * 4
a21 = 180
Answer:
she sprints 180 yards on day 21
Answer: 10
Step-by-step explanation:
10+10 = 20
10 x 10 = 100
mi would do another but i supposed to be in class :P
Answer:
A)The slope of the graph is 1
B) The table is 3
C) The equation is 1/2
D) The table
Step-by-step explanation:
y2-y1/x2-x1=the slope
Pick two undefined points {such as 5,0 and 0,-5)
5-0/0+5=1
The slope is 1.
~~~~~~~~~~
Same equation of slope, you just have to find two points (I chose 2,2 and 4,3
The slope of the equation y=0.5x+1 is 1/2 or 0.5
~~~~~~~~~~
You choose two points (I chose 2,9 and 1,6)
Slope equation
9-6/2-1=3/1=3
Slope is 3
~~~~~~~~~~~
The greatest change is in the table. You know this because it has the greatest slope and if you draw it out on a graph, it has the most significant change.
Good luck!
Shortest to tallest: Plant A, Plant B, Plant C.
Given:
Plant A 1/3 inch tall
Plant B 3/4 inch tall
Plant C 5/6 inch tall
Order from shortest to tallest.
First we need to get the least common multiple of the three fractions.
Multiple of 3: 3, 6, 9, 12
Multiple of 4: 4, 8, 12, 16
Multiple of 6: 6, 12, 18
Their least common multiple is 12. We need to multiply each fraction by the number that will give the product of 12 to the denominator.
Plant A: 1/3 * 4/4 = 4/12
Plant B: 3/4 * 3/3 = 9/12
Plant C: 5/6 * 2/2 = 10/12
Since the denominator is common, we will use the numerator as basis in ordering the plants from shortest to tallest.
4 is less than 9 and 9 is less than 10.
so, Plant A is the shortest, Plant B is the medium height, and Plant C is the tallest.
Answer:
Arley should charge $2.25 for each unbroken cookie.
Step-by-step explanation:
1. This problem has a lot of information to take in. To make things easier, it's vital to condense the problem into the most vital information.
Normal Price (x) = $1.50
Markup = %50 (1.5)
Total Price = 1.5x
Note that the amount of cookies produced and the amount charged for the broken cookie was not written in this condensed format.
The question was only: What <u>price</u> should Arley charge for each <u>unbroken cookie?</u>
Neither the cookies produced or the amount charged were part of the question. In this case, the other information is simply there as a filler.
2. With the information given, a simple formula should be created to find the total price.
The formula for this problem is: 1.5x
As stated above, 1.5 represents the 50% markup while the variable (x) represents the normal price.
When 1.5*1.5 is solved, it comes out to $2.25 dollars.
3. The answer is $2.25 dollars for each unbroken cookie.
