Answer:
Equation is 4 p-3=11
Step-by-step explanation:
Barbara is buying 4 binders each cost same amount.
Let the cost of 1 binder is '$p'.
So, cost of 4 binders = $4 p.
Now, a coupon that gives her $3 off.
So, Barb needs to pay 4 p-3 dollars.
Barb pays a total of $11 when the value of the coupon is subtracted.
So, we can set up equation as
4 p-3=11

Henry enjoys watching his pet frog hop.
Each time his frog hops, Henry skip-counts backward by 100s.
Henry starts his first count at 815.
How many times does his frog have to jump to get to 15?
Explain your thinking below.
8 times does his frog have to jump to get to 15.
Why do frogs hops?The frog jump is a plyometric exercise that primarily works your quads, glutes, and hip flexors. This exercise strengthens the wrists, ankles, knees, hips, and ligaments in the joints. It also stretches your hips and ankles while strengthening your legs and lower back muscles.Frogs jump and hop around using their long, strong legs. Toads, on the other hand, prefer to walk rather than hop. They only move modest distances when they jump or hop. As a result, they don't require long legs like a frog, hence their legs are quite short.The starting number is 815.
the frog hops once (715)
2nd (615)
3rd (515)
4th (415)
5th (315)
6th (215)
7th (115) and
one last time (15) there are 8 numbers.
No. of Times = (815-15)/100 = 8 times.

Hannah opened a bank account. She placed $120 into the bank account and added $30 per week. Now she has $450 in her account. A. Write an equation that represents her savings. B. Find the number of weeks that have passed since she opened her savings account. Explain how you arrived at your answer
The equation that represents her savings is $450 = $120 + $30n.
The number of weeks that have passed since she opened her savings account is 11 weeks.
What equation represents her savings?Total amount saved = amount initially deposited + (amount added weekly x number of weeks)
$450 = $120 + $30n
Where n = number of weeks
In order to determine the value of n, take the following steps:
Combine similar terms = $450 - $120 = 30n
$330 = 30n
Divide both sides by 30
n = 11 weeks

How many milliliters are in
10 teaspoons? 1 tsp = 5 mL
Answer:
about 50
Step-by-step explanation:
Ten teaspoons equal 50 milliliters using the conversion factor 1 tsp = 5 mL.
1 tsp = 5 mL
By multiplying 10 teaspoons by the conversion factor (10 tsp × 5 mL/1 tsp)
10 teaspoons × 5 mL/1 tsp = 50 milliliters
So, there are 50 milliliters in 10 teaspoons.
The conversion factor enables us to maintain the same quantity while converting between different units of measurement. It is an essential tool for performing precise conversions in a variety of disciplines including chemistry, medicine and cooking. For practical applications unit conversions must be understood in order to ensure accurate measurements and consistent outcomes across various measurement systems. Since milliliters are a more commonly used unit of measurement, the conversion in this instance enables us to express the volume of teaspoons in that unit.

What is the center of the circle x ^ 2 + y ^ 2 + 14 = 9x
Find the slope of the line drawn below
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (1, - 3)
m = [tex]\frac{-3-2}{1-1}[/tex] = [tex]\frac{-5}{0}[/tex]
Since division by zero is undefined then the slope of the line is undefined
Rounded to the nearest whole degree, what is the measure of angle boa? ° rounded to the nearest tenth of a centimeter, what is the length of arc bac? cm
1) The measure of ∠BOA is 60.16°.
2) the length of arc BAC is 14.68cm.
What is the formula for arc length?
Arc length = Central Angle(in radian) * Radius
So, length of arc AC = (45π/180) * 8
Arc AC = 2π
Arc AC = 6.28cm
So, length of arc BAC = arc AC+ arc AB
Arc BAC = 6.28 +8.4
Arc BAC = 14.68cm
∠BOA = length of Arc AB / Radius
∠BOA = 8.4/8 = 1.05 radian
∠BOA= 1.05 *(180/π)°
∠BOA=60.16°
Therefore, 1) The measure of ∠BOA is 60.16°.
2) the length of arc BAC is 14.68cm.

While evan and sam are fishing 12kms from shore, their boat springs a leak, and water comes in at a constant rate of 3 gallons per minute. Same starts rowing towards the shore at a constant rate of 24kms per hour while evan bails water out of the boat. What is the slowest rate, in gallons per minute, at which evan can bail if they are to reach the shore with out sinking?
Based on the calculations, the slowest rate is equal to 4 gallons per minute.
Given the following data:
Distance from shore = 12 km.In-rate = 3 gallons per minute. Rowing rate = 24 km per hour.How to calculate the slowest rate.Let's assume the boat would sink if it takes in more than 20 gallons of water.
Conversion:
24 km/h to km/min = [tex]\frac{24 }{60}[/tex] = 0.4 km/min.Translating the word problem into an algebraic expression, we have;
[tex]\frac{12}{0.4} \times 3 - \frac{12}{0.4} \times x\geq 30\\\\\frac{36}{0.4}-\frac{12x}{0.4} \geq 30\\\\90-\frac{12x}{0.4} \geq 30\\\\\frac{12x}{0.4} \geq90+30\\\\\frac{12x}{0.4} \geq120\\\\12x \geq120 \times 0.4\\\\12x \geq 48\\\\x\geq 4[/tex]
Therefore, the slowest rate is equal to 4 gallons per minute.

Now check your work by using the GeoGebra geometry tool to repeat parts A through D. Open GeoGebra e, and complete
each step below. If you need help, follow these instructions for using GeoGebra. You'll take a screenshot of your work when
you're through, so be sure to clearly label your construction as you work.
1. Plot points A, B and C, and draw a polygon, AABC, through the points.
2. Draw a line perpendicular to AC through point B. 3. Label the intersection of the line perpendicular to AC through Band AC point D.
4. Measure and display the slopes of AC and BD.
5. Display the equations of AC and BD in the Algebra margin.
6. Measure and display the lengths of AC and BD.
7. Calculate and display the area o Part F
Compare the calculations displayed in GeoGebra with the calculations you completed in parts A through D. Look in the Algebra
margin too. Do the results in GeoGebra match the results you obtained earlier? If not, where do the discrepancies occur? You
might have to rearrange equations algebraically to determine whether two equations match. Part 6
You've seen two methods for finding the area of AABC-using coordinate algebra (by hand) and using geometry software.
How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using
geometry software?
Answer:
Part E is the pic
Part F is the triangle
sorry if it is kinda blurry
Part 6:
You've seen two methods for finding the area of AABC-using coordinate algebra (by hand) and using geometry software.
How are the two methods similar?
They both apply the fundamentals of triangle geometry in solving the area of a triangle using the formula for the area of triangle 1/2×base of triangle×height of the triangle.
How are they different?
Using coordinate algebra in finding the area of a triangle, you would have to measure coordinates(XY coordinates) of a triangle manually on the graph and find y coordinates based on x. If you used geometry software, it would get these coordinates automatically(based on your graph on the software) and calculate the area of the triangle using the formula.
Why might coordinate algebra be important in making and using geometry software?
A solid grasp of coordinate algebra allows you to understand how the geometry software works because it makes use of the same geometry fundamentals, making it easier for you to tweak and get the best value out of the software for your geometry calculations.

(etc) With a series of numbers we place the dot over the first and last, as with 0.97979797979 . . . (etc) The remarkable feature being that a proper fraction divided by 9s e.g. 46/99 is exactly equal to the numerator with the repeater sign followed by the decimal.
