Answer: 7
Step-by-step explanation:
In 9 hours, Ali can read 63 chapters. To find how many chapters, on average, he can read per hour, we divide 63 by 9 to get 7.
This is how we put it as an equation:
[tex]9 hours = 63 chapters\\1 hour = \frac{63}{9} chapters \\1 hour = 7 chapters[/tex]

The distances between the given points are 6.4 units, 7.2 units, 5 units and 7 units
What is distance between points?Distance between two points is the length of the line segment that connects the two points in a plane.
Given that are some points, we need to find the distance between them.
The distance between two points is given by,
C = √(x₂-x₁)²+(y₂-y₁)²
1) (0, 2) and (5, -2)
C = √(5-0)²+(-2-2)²
= √25+16
= √41 = 6.4 units
2) (-4, -3) and (2, 1)
C = √(2+4)²+(1+3)²
= √36+16
= √52 = 7.2 units
3) (0, 0) and (-4, -3)
C = √(-4-0)²+(-3-0)²
= √16+9
= √25 = 5 units
4) (-3, 4) and (2, -3)
C = √(2-3)²+(-3-4)²
= √1+49
= √50 = 7 units
Hence, the distances between the given points are 6.4 units, 7.2 units, 5 units and 7 units

The Haverstown theater club is selling tickets for dinner and a show. They already have props and costumes, but they spend $142.50 on food. If they charge $9.50 for each ticket, how many tickets do they need to sell to cover their costs?
Answer:
15 tickets
Step-by-step explanation:
If the theater club needs $142.50 and each ticket costs $9.50, we need to divide 142.5/9.5 to determine how many tickets must be sold, which gets us 15.

Answer:
The height is 5.6 units.
Step-by-step explanation:
The height can be calculated using this formula
[tex]h=\sqrt{a^2-\frac{b^2}{4} }[/tex]
Let [tex]a[/tex] be the base of the triangle along the horizontal.
Let [tex]b[/tex] be the side of the triangle.
In an isosceles triangle has 2 sides that are equal in length.
Numerical Evaluation
In this example we are given
[tex]a=6\\b=3\sqrt{2}[/tex]
Substituting our values into the equation gives us
[tex]h=\sqrt{6^2-\frac{\left(3\sqrt{2} \right) ^2}{4} }[/tex]
Lets solve for [tex]h[/tex].
Evaluate [tex]6^2[/tex].
[tex]h=\sqrt{36-\frac{\left(3\sqrt{2} \right) ^2}{4} }[/tex]
Apply the product rule to [tex]3\sqrt{2}[/tex].
[tex]h=\sqrt{36-\frac{3^2\sqrt{2}^2 }{4} }[/tex]
Evaluate [tex]3^2[/tex].
[tex]h=\sqrt{36-\frac{9\sqrt{2}^2 }{4} }[/tex]
Rewrite [tex]\sqrt{2}^2[/tex] as [tex]2[/tex].
[tex]h=\sqrt{36-\frac{9*2 }{4} }[/tex]
Evaluate [tex]9*2[/tex].
[tex]h=\sqrt{36-\frac{18 }{4} }[/tex]
Factor [tex]2[/tex] out of [tex]18[/tex] and [tex]2[/tex] out of [tex]4[/tex].
[tex]h=\sqrt{36-\frac{2(9) }{2(2)} }[/tex]
Cancel the common factor of [tex]2[/tex].
[tex]h=\sqrt{36-\frac{9 }{2} }[/tex]
To write [tex]36[/tex] as a fraction with a common denominator, multiply by [tex]\frac{2}{2}[/tex].
[tex]h=\sqrt{36*\frac{2}{2} -\frac{9 }{2} }[/tex]
Combine the numerators over the common denominator.
[tex]h=\sqrt{\frac{36*2-9}{2}[/tex]
Multiply [tex]36[/tex] by [tex]2[/tex] then subtract [tex]9[/tex].
[tex]h=\sqrt{\frac{63}{2} }[/tex]
Evaluate [tex]\sqrt{\frac{63}{2} }[/tex].
[tex]h=5.6125[/tex]
Round to nearest tenth.
[tex]h=5.6[/tex]

Answer:
8% as a fraction can be expressed as 8/100 or 4/50.
Explanation:
Percentages are a way of expressing a number as a fraction of 100. The symbol % represents "per hundred" or "out of 100." So, 8% can be thought of as 8 out of 100 or 8/100.
When we convert a percentage to a fraction, the numerator (top part of the fraction) represents the percentage value and the denominator (bottom part of the fraction) is set to 100. This is because 100 represents the whole, and the numerator represents a part of that whole.
In this case, 8% as a fraction is 8/100, which can be simplified to 4/50.
Answer: hope this helps ♡
8% = [tex]\frac{8}{100}[/tex] = [tex]\frac{2}{25}[/tex]
Step-by-step explanation:
% = something out of a hundred (not out of 10)
eg: 25% = 25 out of a hundred
so 8% = (8 out of a hundred) [tex]\frac{8}{100}[/tex] = [tex]\frac{4}{50}[/tex] = [tex]\frac{2}{25}[/tex] (simplified answer)
(100 divided by 2 = 50 50 divided by 2 = 25)
(8 divided by 2 = 4 4 divided by 2 = 2)

Answer: 8.2% rounded to the nearest tenth
Step-by-step explanation:
The original price was 85.78 excluding the sales tax, the total price including the sales tax was 92.82. Subtract 92.82 minus 85.78 and you get 7.04 which was the amount added due to sales tax. Now you will need to find the percentage. What percent is 7.04 of 85.78. You can use the formula p=x times 100 divided by y. x is 7.04 times 100 is 704 then divided by y which is 85.78 you get 8.2 which is your percent.

^PREVIOUS QUESTION^ THE ANSWER WAS 78
THE QUESTION
You must read 130 pages for homework. Reading at the same rate as the previous question, can you complete the assignment in two hours? Explain your reasoning
No, it is not possible to complete the assignment in two hours if reading at the same rate as the previous question. The previous question states that 52 pages can be read in an hour, meaning 104 pages can be read in two hours. Therefore, 130 pages cannot be completed in two hours.
Answer:
No.
Step-by-step explanation:
It isn't possible to read 130 pages for homework in 2 hours because like the previous question says, you are only able to tead 52 pages per hour. Now 52 multiplied by 2 is only equal to 104 pages read in two hours. This means that you will have left 26 pages unread for your homework. Although, you are able to read 130 pages in 2 and a half hours since for two hours you are able to read 104 pages, and the left over pages (26 pages) is half of 52 pages which is our hourly rate, meaning that every half hour, we are able to read 26 pages!

A sector of a circle of radius 8cm has an area of 120° at the centre. Find its perimeter
Answer:
Area of the sector = [tex]24\pi ^{2}[/tex]
The perimeter of the sector of the given circle is 32.75 cm.
The perimeter of a sector is given by the sum of the arc length and the two radii that form the sector. To find the perimeter of this sector, we need to find the length of the arc and the two radii.
The area of the sector is given as 120° at the center. We can use this information to find the length of the arc by using the formula for the area of a sector:
Area of sector = (angle/360) x πr²
where r is the radius of the circle and angle is the central angle of the sector in degrees.
In this case, we have:
120/360 x π x 8² = 33.51 cm² (rounded to two decimal places)
The length of the arc can be found by using the formula:
Arc length = (angle/360) x 2πr
In this case, we have:
(120/360) x 2π x 8 = 16.75 cm (rounded to two decimal places)
The two radii that form the sector have lengths of 8 cm each.
Therefore, the perimeter of the sector is the sum of the arc length and the two radii:
Perimeter = arc length + 2r
= 16.75 + 2(8)
= 32.75 cm (rounded to two decimal places)
Therefore, the perimeter of the sector is approximately 32.75 cm.
