The question is down below in the picture pls solve
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:
Jessica and Luke rates are inequivalent.
Step-by-step explanation:
Jessica had 4 laps and had 9 minutes.
4 Laps/9 Minutes = 12 laps/27 Minute
12 Laps/27 Minutes ≠ 8 Laps/ 27 Minute

^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!
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:
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)
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.

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

1 hour - how many more hours will the tank be out of gas
Step-by-step explanation:
The path of the boat, the horizontal distance and vertical distance from the dock are in the shape of a right triangle
Distance of boat from dock after 1 hour
d = [tex]\sqrt{6^2 + 8^2} = \sqrt{36 + 64} = \sqrt{100} = 10\;mi\\[/tex]
Speed of boat = 10mph
distance that can be traveled with 4 gallons of fuel
d = 5 mpg x 4 g = 20 miles
The boat has already traveled 10miles in the diagonal direction. Assuming same trajectory, the boat can travel 20 - 10 = 10 miles more
10 miles ==> 1 hour more at 10 mph
So additional time the boat can travel = 1 hour
