The unshaded area inside the figure to the right is 648 in.² Use this fact to write an equation involving x. Then solve the equation to find the value of x.
Length of rectangle is 40 inches
Width of rectangle is 22 inches
Border inside rectangle is x
Answers
The second order polynomial that involves the variable x (border inside the rectangle) and associated to the unshaded area is x² - 62 · x + 232 = 0.
How to derive an expression for the area of an unshaded region of a rectangle
The area of a rectangle (A), in square inches, is equal to the product of its width (w), in inches, and its height (h), in inches. According to the figure, we have two proportional rectangles and we need to derive an expression that describes the value of the unshaded area.
If we know that A = 648 in², w = 22 - x and h = 40 - x, then the expression is derived below:
A = w · h
(22 - x) · (40 - x) = 648
40 · (22 - x) - x · (22 - x) = 648
880 - 40 · x - 22 · x + x² = 648
x² - 62 · x + 232 = 0
The second order polynomial that involves the variable x (border inside the rectangle) and associated to the unshaded area is x² - 62 · x + 232 = 0. [tex]\blacksquare[/tex]

Solve for h. -18 + h = 28
h=10
Answers
Answer:
h = 46
Step-by-step explanation:
Have unknowns (h) on one side and knowns on other side.
-18 + h = 28 Add 18 on both side to move it to the right side.
h = 28 + 18
h = 46
Answer:
[tex]\boxed{\sf{h=46}}[/tex]Step-by-step explanation:
Isolate the term of h from one side of the equation.
-18+h=28First, switch sides.
⇒ h-18=28
Add by 18 from both sides.
⇒ h-18+18=28+18
Solve.
Add the numbers from left to right.
⇒ 28+18=46
⇒ h=46
Therefore, the correct answer is h=46.I hope this helps! Let me know if you have any questions.
In circle k(O),
AC is a diameter,
AB is a chord, and
MA is tangent to the circle. Angle ∠MAB is acute. Prove that m∠MAB=m∠ACB
Answers
The circle and the lines AC & AB are illustrations of congruent angles
See below for the proof that the angles ∠ACB and ∠MAB are equal
How to prove that ∠MAB=∠ACBTo prove that ∠MAB=∠ACB, we make use of the attached diagram
From the attached diagram, we have:
∠MAB = x°
The angle at between a tangent and a radius or a diameter is a right angle.
This means that:
∠MAB + ∠BAC = 90°
Substitute ∠MAB = x°
x° + ∠BAC = 90°
Subtract x from both sides
∠BAC = 90° - x°
The angle at in a semicircle is a right angle.
This means that:
∠CBA = 90°
The angles in a triangle add up to 180°.
So, we have:
∠BAC + ∠CBA + ∠ACB = 180°
Substitute ∠CBA = 90° and ∠BAC = 90° - x°
90° - x° + 90° + ∠ACB = 180°
Evaluate the like terms
180° - x° + ∠ACB = 180°
Subtract 180° from both sides
- x° + ∠ACB = 0
Add x° to both sides
∠ACB = x°
Recall that:
∠MAB = x°
So, we have:
∠ACB = ∠MAB = x°
Hence, the angles ∠ACB and ∠MAB are equal

Step-by-step explanation:
1) the sum of the internal angles of the given figure is:
S=180*(n-2), where 'n' is number of the angles.
2) according to the rule above the sum of all the internal angles is 720°;
3) according to the item 2, m∠A+m∠B+m∠C+m∠D+m∠E+m∠F=720°. If all the angles are known, then it is possible to re-write this equation as:
6x+(3x+45)+7x+(4x+2)+(2x+15)+(x-9)=720;
23x=667; ⇔ x=29.
4) if x=29, then m∠A=174; m∠B=132; m∠C=203; m∠D=118; m∠E=73; m∠F=20°.

What is metric system?The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.
The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.
Thus, the volume of sugar solution has been reported in mL.
The given sugar solution has volume of 1.32 fl. Oz
The volume in mL can be given as:

Susan mixes red and blue paint to make purple.
Red
2 parts of red paint with 3 parts of blue paint make purple.
Susan has 50 ml of red and 100 ml of blue.
What is the maximum amount of purple she can make?
Answers
Answer:
125 mL
Step-by-step explanation:
Susan's purple paint has the proportions 2 parts red and 3 parts blue. That means the total amount of paint is (2+3)/2 = 5/2 the amount of red paint, or (2+3)/3 = 5/3 the amount of blue paint.
__
The total amount of paint Susan has is 50 mL +100 mL = 150 mL.
If Susan uses all of her red paint (with sufficient blue paint), she would have an amount of purple paint equal to ...
(5/2)(50 mL) = 125 mL . . . . purple paint
If Susan uses all of her blue paint (with sufficient red paint), she would have an amount of purple paint equal to ...
(5/3)(100 mL) = 166 2/3 mL . . . . purple paint
This is more paint than Susan has, so the amount of purple paint Susan can make is limited by the amount of red paint she has. Susan can make a maximum of 125 mL of purple paint.
_____
Additional comment
Essentially, we have rewritten the proportion to show corresponding amounts of red and blue paint:
red : blue = 2 : 3 = 50 : 75 = 66 2/3 : 100
Since Susan has only 50 mL of red, and more than 75 mL of blue, the red paint is the limiting ingredient.

Answers
Answer:
y = 3,224x + 750
Step-by-step explanation:
Assuming the scholarship and grants are applied using the slope intercept form y=mx+b where m is the slope in this case the cost per year attending x the number of years attended and b the y intercept which in this case is the one time fee subtracting 13,774 by 10,550 gives us 3,224.
Since the one time fee is only in place once that would make it the y intercept therefore y=3,224x+750 is the correct answer

A translation followed by a rotation
A rotation of 270 degrees about the origin
A dilation followed by a translation
Answers
Answer:
A dilation followed by a translationStep-by-step explanation:
A dilation would change the size of the figureHence, on changing it, the transformation will form an image that is not congruent to its pre-imageThe transformation or sequence of transformations that would produce an image that is not congruent to its pre-image is:
A dilation followed by a translation.
If we follow a dilation with a translation, the image will be both resized and shifted. The combination of these transformations will result in an image that is not congruent to its pre-image.
On the other hand:
A translation of (x − 2, y + 9) will shift the object without changing its size or shape. The resulting image will be congruent to the pre-image.
A translation followed by a rotation can result in a congruent image if the rotation angle and translation distance are appropriately chosen. It depends on the specific values used in the transformation.
A rotation of 270 degrees about the origin will preserve the shape and size of the object. The resulting image will be congruent to the pre-image.
