Hanna walks a total of 3 1/6 miles before and after school.

To find how many miles Hanna walks before and after school, we can add the distances she walks to school and to work.

Distance to school = 1 2/3 miles

Distance to work = 1 1/2 miles

To find the total distance Hanna walks before and after school, add the two distances:

Total distance = 1 2/3 + 1 1/2

To add these fractions, we need to convert them to have a common denominator, which is 6:

1 2/3 = (3/3 + 2/3) = 5/3

1 1/2 = (3/2)

Now, we can add the fractions:

Total distance = 5/3 + 3/2

To add these fractions, we need to have a common denominator, which is 6:

Total distance = (5/3) * (2/2) + (3/2) * (3/3)

Total distance = 10/6 + 9/6

Now, add the fractions:

Total distance = 19/6

We can simplify this fraction:

Total distance = 3 1/6 miles

So, Hanna walks a total of 3 1/6 miles before and after school.

To solve the equation x²−12x=−6, Lamar should first move the constant to the other side and complete the square, leading to x = 6 ±√30. This equation, which is a type of quadratic or second-order polynomial, may have two solutions, a typical characteristic of such equations.

The equation presented is x²−12x=−6. To solve this equation by completing the square, we first move the constant term to the other side, which leads to x² - 12x = -6, or x² - 12x + 36 = -6 + 36. We added 36 on both sides because (12/2)² = 36, which is a step in completing the square for the equation. Thus, we have (x-6)² = 30. Now, solve for x: x - 6 = ±√30, so x = 6 ±√30.

This method, known as completing the square, is a typical approach to solving quadratic equations. The general quadratic equation ax²+bx+c = 0 can also be solved using the quadratic formula -b ± √(b² - 4ac) / 2a. With both methods, remember that a quadratic equation will usually have two solutions, as it is a second-order polynomial.

Max cost of 15 bats = 15 x 35 = $535

Min cost of 15 bats = 15 x 20 = $300

Max cost of 12 gloves = 12 x 60 = $720

Mix cost of 12 gloves = 12 x 30 = $360

Min total cost = 360 + 300 = $660

Max total cost = 535 + 720 = $1255

The range is from  $660 to $1255

$45 is 75% of the original price. 75/3 is 25, so divide 45/3=15. $15 is 1/4 of the original price. 15*4=60

The original price of the pair of shoes is $60.

To find the original price of a pair of shoes, we can use the given information that the sale price is $45 after a 25% discount.

Let's assume the original price of the shoes is "x" dollars.

The discount of 25% means that the sale price is equal to 75% (100% - 25%) of the original price.

Mathematically, we can express this as:

Sale price = Original price * (Discount percentage in decimal form)

$45 = x * (0.75)

To find the original price (x), we divide both sides of the equation by 0.75:

$45 / 0.75 = x

x = $60

Therefore, the original price of the pair of shoes is $60.

To solve the linear system by graphing, convert the equations to slope-intercept form, plot the lines, and find the point of intersection.

To solve the given linear system by graphing, we need to graph both equations on the same coordinate plane and find the point of intersection.

Step 1: Convert both equations into slope-intercept form, y = mx + b.

Step 2: Plot the y-intercepts (b values) of both equations and use the slopes (m values) to draw the lines.

Step 3: The point where the lines intersect is the solution to the system of equations. In this case, the solution is x = 6 and y = 0.

The answer is C.37.41

to solve  for the dimensions (x+7)(x+2)=66,

we can first use the foiling method to simplify the left side.

x^2 + 2x + 7x + 14 = 66

x^2 + 9x + 14 = 66

now, subtract 66 from both sides.

x^2 + 9x - 52 = 0

now, split this into two parentheses.

(x + 13)(x - 4)

since the root of -13 would give you negative values, x=4. This means that the dimensions of the rectangle are 11 and 6.

The dimensions of the rectangle is 11 by 6 inches

The dimensions are given as:

x + 7 and x + 2

The area is given as:

Area = 66

The area of a rectangle is:

Area = Length * Width

So, we have:

(x + 7) * (x + 2) = 66

Express 66 as 11 * 6

(x + 7) * (x + 2) = 11 * 6

By comparison, we have:

x + 7 = 11 and x + 2 = 6

Solve for x

x = 4 and x = 4

Substitute 4 for x in x + 7 and x + 2

x + 7 = 4 + 7 = 11

x + 2 = 4 + 2 = 6

Hence, the dimensions of the rectangle is 11 by 6 inches

The discriminant of the quadratic equation p²+6p+9=0 is zero, suggesting that it has exactly one real, repeated solution.

The discriminant of the quadratic equation p²+6p+9=0 is calculated using the formula D=b²-4ac, where a, b, and c are the coefficients of the quadratic equation ax²+bx+c=0. In this equation, a=1, b=6, and c=9. Substituting these values into the discriminant formula gives us:

D = b² - 4ac

D = (6)² - 4(1)(9)

D = 36 - 36

D = 0

The discriminant is zero, which indicates that the quadratic equation has one real, repeated solution, meaning the parabola touches the x-axis at a single point.

Isolate the p. Note the equal sign. What you do to one side, you do to the other. Multiply 7/6 to both sides

(-2)(7/6) = (6/7)(7/6)p

p = (-2)(7/6)

Multiply -2 and 7, then divide by 6

p = (-2 x 7)/6

p = -14/6
