The graph below represents the relationship between the number of days a book is overdue and the library fine charged. A graph titled Library Fines. The horizontal axis shows days overdue and the vertical axis shows the fine (dollars). The line shows an increase to $10 at 19 days overdue, then constant. Christen returned an overdue book to the library. Her fine was the same as it would have been if she returned the book the previous day. Which of the answer choices below could be the number of days Christen’s book is overdue? 10 14 18 22

Answer:

46.4 in ^2

Step-by-step explanation:

We know the area of a rectangle is found by

A = l*w  where l is the length and w is the width

A = 14.5 * 3.2

A = 46.4 in ^2

Answer:

This statement is not true. (Alternate Interior Angles Theorem)

Step-by-step explanation:

<6 and <3 are both interior angles, meaning that they are on the interior of two transversals. They are also alternating the transversal, so they are alternate interior angles. The Alternate Interior Angles Theorem states that if a transversal crosses the set of parallel lines, the alternate interior angles are congruent. This means that <6 and <3 would be congruent to one another, so they would have to measure the exact same degree. Hope this helps! :)

Answer: $97.2

Step-by-step explanation: 75+8%/100=81+20%/100=97.2

If their lunch costs $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$. He will totally pay $ 97.2.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

It is given that, Franklin treated his sister to lunch while visiting her in Ashland. Their lunch costs $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$.

We have to apply arithmetic operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

If their lunch costs $75 and the sales tax in Ashland is 8%.

= 75+8% of 75

=75+(8/100)×75

=81

If Franklin left a 20% tip on the 75$

=81+20% of 81

=$ 97.2

Thus, if their lunch costs $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$. He will totally pay $ 97.2.

Answer:

Mary

Step-by-step explanation:

You have to change the fractions so that the denominator is the same in both of them. To do this, you can multiply the numerator and denominator in 3/4 by 2. This would equal 6/8.

6/8 > 3/8

This shows that Mary climbed higher.

Answer:

The number is 69.

Step-by-step explanation:

[tex]\sqrt{(x+12)} =9[/tex]

Square both sides.

[tex]x+12=81[/tex]

Solve for x. Subtract 12 from both sides.

[tex]x=81-12\\x=69[/tex]

Check.

[tex]\sqrt{(69+12)} =9\\\sqrt{81} =9[/tex]

Step-by-step explanation:

total student in the class = 30

10% are male students

The amount of metal he will need to cover the back of the shelves is 180 inches².

The figure above is like a composite figure. Therefore, lets find the area.

The area of the figure is the sum of the whole individual 2 dimensional shapes in the composite figure.

Therefore, two rectangles can be drawn from it.

area of rectangle = lw

where

l = length

w = width

Therefore,

area of rectangle 1 = 9 × 8 = 72 inches²

area of rectangle 2 = 6 × 18 = 108 inches²

Total area = 108 + 72 = 180 inches²

Therefore, the amount of metal he will need to cover the back of the shelves is 180 inches².

Answer:

Step-by-step explanation:

in 10 hrs distance covered=speed×time=15×10=150 nautical miles.

x²=600²+150²-2×600×150×cos 20°

x²=360,000+22,500-180,000×cos 20°

x=√(382,500+180,000×cos 20°)

x\approx 742.73 nautical miles

time taken=742.73/15 \approx ~49.52 hours

total time taken=10+49.52=59.52 hours

applying sine formula

[tex]\frac{sin ~B}{150} =\frac{sin~20}{742.73} \\\sin~B=\frac{150}{742.73} \times~sin~20\\B=\sin^{-1} [\frac{150}{742.73} \times \sin~20]\\B\approx~3.96 ^\circ\\B\approx 4^\circ[/tex]

Answer:

  B.  Substitute for x in the first equation

Step-by-step explanation:

The solution to a system of equations in which one is quadratic and the other is linear will necessarily involve solving a quadratic equation. Generally, we want to arrive at that quadratic as early as possible in the solution process.

Here, we have a linear expression for x, so it is pretty simple to use that to substitute for x in the first equation:

  (2y -1)² -(2y -1) +3y = 5 . . . . substitute for x

  4y² -4y +1 -2y +1 +3y = 5 . . . . eliminate parentheses

  4y² -3y -3 = 0 . . . . quadratic in y in standard form

This does not have integer solutions, so it is perhaps best solved using the quadratic formula.

  [tex]y=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(4)(-3)}}{2(4)}=\dfrac{3\pm\sqrt{57}}{8}[/tex]

Answer:

12

Step-by-step explanation:

Use Pythagorean Theorem

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

[tex]9^{2}[/tex] + [tex]b^{2}[/tex] = [tex]15^{2}[/tex]

81 + [tex]b^{2}[/tex] = 225

[tex]b^{2}[/tex] = 144   (subtract 81 both sides)

b = 12      (square root each side)

➣ The hypotenuse of a right triangle measures 15 cm.

➣ one of its legs (base) measures 9 cm.

➣ the measure of the other leg (perpendicular).

➣ to round the answer to nearest tenth.

Here,

p = perpendicular of the triangle

b = base of the triangle

h = hypotenuse of the triangle

Using the Pythagoras Theorem,

(height)² = (perpendicular)² +(base)²

i.e h² = p² + b²

➩ (15)² = p² + (9)²

➩ p² = (15)² - (9)²

➩ p² = 225 - 81

➩ p² = 144

➩ p = √144

➩ p = 12 cm

Answer:

a.

Step-by-step explanation:

Since the denomaitor is the same, just add straight across.

[tex] \frac{4n - 10}{2n - 5} [/tex]

The numerator can be factored.

The greater common factor is 2 so we have
