Step-by-step explanation:

The distances between the given points are 6.4 units, 7.2 units, 5 units and 7 units

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

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]

[tex]\frac{5}{12}[/tex] cups of dog food is recommended for a 25-pound adult dog.

Step-by-step explanation:

Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol)  :)

10 lb = ⅙ Or 0.1666666 cups

1 lb = ? cups

[tex]\frac{0.16}{10}[/tex] = 0.01666666

1 lb = 0.01666666 cups

25 lb = 0.01666666 × 25 cups

25 lb = 0.416666667 Or [tex]\frac{5}{12}[/tex] cups

(Or:      10lb= ⅙              20lb= ⅙+⅙ = [tex]\frac{2}{6}[/tex]              5lb= ⅙ ÷ 2= [tex]\frac{1}{12}[/tex] (10lb÷2)       25lb = [tex]\frac{1}{12}+\frac{2}{6}[/tex] = [tex]\frac{5}{12}[/tex] ≈ 0.416666667     (25=20+5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer: Foremost sum could Be a = $250.09 Principal sum is B = $400. Account B earned you the foremost intrigued the first​ month The equation for straightforward intrigued is communicated as I = PRT/100 Where P = the central or starting sum of cash invested. R = intrigued rate T = time

On account A,

I = $6.94

R = 3.7%

T = 9 months = 9/12 = 0.75 years.

On account B,

I = $13.80

R = 2.3%

T = 18 months = 18/12 = 1.5 years

To decide the account that earned more intrigued within the to begin with month we separate the intrigued by the number of months.

$6.94/9 = $0.7711

$13.80/18 = $0.7667

Account B earned you the foremost intrigued the first​ month since $0.7667 is higher than $0.7711.

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.

Answer:

No, Noah's method does not always work.

Step-by-step explanation:

Let's say we're trying to find 40% of 80 instead of 20% of 60.

If we divide 80 by 5, like Noah says, we get 16, which is not 40% of 80.

The proper solution would be to multiply the number by the percentage converted to a decimal.

In this case, it would be 80 × 0.4, which is 32.

When you try to solve 20% of 60, you can say 60 × 0.2, which also gets 16.

Answer:

No it doesn't

Step-by-step explanation:

His method never works because multiplying by does not give the same result as dividing by 5. AI Recommended Answer: To find 20% of a number, divide the number by 5. For example, 20% of 60 is 12.

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)

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
