The possible number represented by the 9 counter is 27
How to determine the possible number?The counters are given as:
12 counters and 15 counters
When added, we get a number that can be represented by 9 counters.
This means that:
12 + 15 = 9x
Evaluate the sum
27 = 9x
Divide by 9
x = 3
When subtracted, you need more than 9 counters.
This means that:
x = 15 - 12 = 3
So, we conclude that the number is a multiple of 3 and 9
In other words, the decimal number is a multiple of 9 (i.e. 27)
Hence, the possible number is 27

Lisa is on a trip of 1,579 miles. She has already traveled 220 miles. She has 3 days left in her trip. How many miles does she need to travel each day to complete the trip?
A. 673
B. 906
C. 1,359
D. 453
Answer: D. 453
Step-by-step explanation:
First, we will find out how many miles she has left.
-> We will subtract miles travled from total trip.
1,579 miles - 220 miles = 1,359 miles
Now, we will find the answer to your question.
-> If she has three days left in her trip, we will divide the rest of the miles to travel by 3.
1,359 miles / 3 days = 453 miles
The answer to your question is;
D. 453

The complete statement is 67000 pounds is equivalent to 33.5 tons
How to convert the units?The unit is given as:
Weight = 67000 pounds
As a general rule;
1 pound = 0.0005 tons
Multiply both sides by 67000
67000 * 1 pound = 67000 * 0.0005 tons
Evaluate
67000 pounds = 33.5 tons
Hence, 67000 pounds is equivalent to 33.5 tons

Step-by-step explanation:
y = -x² + x + 2
y = -x + 3
1. Set the two equations equal to each other:
-x² + x + 2 = -x + 3
2. move one of the equations to the other side:
-x² + 2x - 1
3. Factor out a -1:
-1 (-x² + 2x - 1) = 0
x² - 2x + 1
4. Factor:
(x - 1)(x - 1)
x = 1
5. Plug in 1 to one of the equations:
y = -x + 3
y = -(1) + 3
y = 2

Given g of x equals cube root of the quantity x plus 6, on what interval is the function negative?
The interval for the function to be negative will be (-∞<x<-7).
What is a function?A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
Here we have a function:-
g(x) = ∛(x+6)
If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-
(-∞<x<-7).
Therefore interval for the function to be negative will be (-∞<x<-7).

Wyatt is paying back a loan with a nominal interest rate of 13.62%. If the interest is compounded quarterly, how much greater is Wyatt’s effective interest rate than his nominal interest rate? a. 0.96 percentage points b. 0.40 percentage points c. 0.25 percentage points d. 0.71 percentage points
Answer:
d. 0.71 percentage points
Step-by-step explanation:
13.62 % is .1362 in decimal
quarterly period compounding makes periodic (quarterly) interes rate
= .1362/4 = .03405 per period
FOUR periods in a year
(1+ .03405)^4 = 1.1433
which means effective interest is .1433 or 14.33 %
14.33 - 13.62 = .7115 percentage points difference

Of the 400 students, 120 students like to drink coffee, 80 students like to drink tea, 160 students like both and 40 students do not like any of these drinks.
How many students like to drink coffee, tea, or none?Cofee: 70% of 400 = 280 students
Tea: 60% of 400 = 240 students
None: 10% of 400= 40 students
This means that 360 students like coffee, tea or both.
How many students like both drinks?280 + 240 (students who drink either coffe or tea)= 520 - 360 (real number of students who like coffee or tea) = 160 (students who like both coffee and tea.
Moreover, it can be inferred 80 students like tea and 120 studetns like coffee.
How to represented it in a Venn diagram?Set A: Students who like coffee 120 students.Set B: Students who like tea 80 students.Set A^B: Students who ike both drinks 160 studentsOutside the sets 40 students who do not like any of the drinks.

The volume of a right cone is 168π units^3. If its diameter measures 12 units, find its height
Answer:
14 unitsStep-by-step explanation:
In the question, it is given that a right cone has a diameter of 12 units and volume of 168π units³ and we have to find the height of the cone.
[tex] \: [/tex]
To Find the height of the cone, we must know this formula :
[tex]\\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { \dfrac{1}{3} \: \pi r^2h ={ Volume_{(cone) }}}}}}}}} \\ \\[/tex]
Where,
r refers to the radius of the cone. Here, the diameter is 12, Therefore the radius will be 6 units.h refers to the height of the cone.Now, we will substitute the values in the formula :
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{1}{3} \times \pi \times (6)^2 \times h = 168 \pi}}}}}}} \\ \\[/tex]
Cancelling π from both sides we get :
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{1}{3} \times \cancel\pi \times 36 \times h = 168 \cancel\pi}}}}}}} \\ \\[/tex]
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{1}{3} \ \times 36 \times h = 168 }}}}}}} \\ \\[/tex]
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{36}{3} \times h = 168 }}}}}}} \\ \\[/tex]
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { 12 \times h = 168 }}}}}}} \\ \\[/tex]
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { h = \frac{168}{12} }}}}}}} \\ \\[/tex]
[tex]\\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { h ={14 }}}}}}}} \\ \\[/tex]
Therefore,
The height of the cone is 14 units .
