A teacher bought markers at a cost of $3 per set. The teacher had a $2-off coupon to use toward the total cost of the markers bought
Answer: A
Explanation:
if we look at the chart for A,
in the first row...
we see that the teacher brought 3 sets of markers.
If 1 set is $3, then 3 sets is $9 (<-- 3*3).
Now we know that the teacher has a $2-off coupon, so 9 - 2 = $7
we will repeat this with 12 sets
in the third row...
If 1 set is $3, then 12 sets is $36 (<--12*3)
We will use now the teacher's $2-off coupon, so 36 - 2 = $34
these values are correctly shown on chart A, therefore the correct answer is
A.An organization must have all of the following except _____________. A. Structure b. A group of people c. Many employees d. Compatible goals please select the best answer from the choices provided a b c d

You have $750 in your savings account. You owe your brother $30 and your mom $75. What is your current net worth?
Answer is 25
Explanation:
30/750
Based on the given information, the net worth is $645 when you have $750 in your savings account.
What is a saving account?A savings account is a fundamental kind of investment product that enables you to store your money and often earn a tiny bit of interest. A savings account is a bank account created to house money you don't intend to spend right away.
The net worth of any individual is calculated as the value of your assets less your obligations. Entire assets minus total liabilities to get the amount of net worth.
To calculate net worth
Balance in your savings account = $750
Liabilities:
amount from Brother = $30
amount from Mom = $75
Total liabilities = $105
Net worth = assets - liabilities
= $750 - $105
= $645
Therefore, the total net worth or equity is $645.

What are the dimensions of the rectangle? 8 by 5 10 by 4 11 by 9 13 by 7
The dimensions of a rectangle with an area of 40 square units and the length is 6 more than the width is 10 by 4.
Area of a rectanglearea of a rectangle = lw
where
l = lengthw = widthTherefore,
area = 40 square units
The length is 6 unit greater than the width. Hence,
l = 6 + w
Therefore,
40 = w(6 + w)
40 = 6w + w²
w² + 6w - 40 = 0
w² - 4w + 10w - 40 = 0
w(w - 4) + 10(w - 4) = 0
(w + 10)(w - 4) = 0
w = - 10 or 4

During a rainfall, the depth of water in a rain gauge increases at a rate modeled by r(t)=0.5+tcos(πt380) r ( t ) = 0.5 + t cos ( π t 3 80 ) , where t is the time in hours since the start of the rainfall and r (t) r ( t ) is measured in centimeters per hour. how much did the depth of water in the rain gauge increase from t = 0 t = 0 to t = 3 t = 3 hours?
The function r(t)= 0.5 + t cos(πt³/80) is an illustration of a cosine function
The depth of water in the rain gauge increases by 1.466cm from t = 0 to t = 3
How to determine the increase in water depth?The function is given as:
r(t)= 0.5 + t cos(πt³/80)
When t = 0, the depth of water is:
r(0)= 0.5 + 0 * cos(π *0³/80)
Evaluate
r(0) = 0.5
When t = 3, the depth of water is:
r(3)= 0.5 + 3 * cos(π *3³/80)
Evaluate
r(3)= 1.966
Calculate the difference (d) in the depths
d = r(3) - r(0)
So, we have:
d = 1.966 - 0.5
Evaluate
d = 1.466
Hence, the depth of water in the rain gauge increases by 1.466cm from t = 0 to t = 3

with each of a, b, and c greater than 0. Then the plane has intercepts with coordinates
[tex]y=z=0 \implies ax = 1 \implies x = \dfrac1a[/tex]
