Melanie is standing on the 10 m diving platform. Her coach is on the ground to the
left of her, while her parents are on the ground to the right of her. Her coach is
looking at her at an angle of 38° with the ground, while her parents are looking at her
at an angle of 30° with the ground. If the angle at the base of the platform between
Melanie's coach and Melanie's parents is 105°, how far apart are her coach and her parents to the nearest metre?

Answer:

I think it's 60%

Step-by-step explanation:

Answer:

30 is the correct choice.

Step-by-step explanation:

150 = {baseball} + {cricket} + {soccer} - {exactly 2 sports} - 2*{exactly 3 sports} + {none of the ports}

150 = 66 + 45 + 42 - 27 - 2*3 + {none of the ports}

--> {none of the ports} = 30

Answer:

6 hours and 45 minutes

Step-by-step explanation:

if you divide 3 hours by four songs you deduce that it take 45 minutes to record one song.

8 is double 4 so it will take 3more hours plus the 45 minutes for the ninth song.

3+3+.45= 6.45

Answer:

60

Step-by-step explanation:

interior angles for a triangle is 180°

180 ÷ 3 sides = 60°

The given regular polygon is an equilateral triangle.

The measure of one interior angle of it is 60°.

The measure of one exterior angle is 120°.

For an n-sided polygon,

The sum of all interior angles = (n - 2)180°.

The sum of all exterior angles = 360°.

We know, that a regular polygon has all sides equal, all interior angles equal, and also all exterior angles equal.

Therefore,

The value of each interior angle of a regular polygon = (The sum of all interior angles)/n,

or, The value of each interior angle of a regular polygon = {(n - 2)180°}/n.

The value of each exterior angle of a regular polygon = (The sum of all exterior angles)/n,

or, The value of each exterior angle of a regular polygon = 360°/n.

In the question, we are asked to find the measure of one interior and one exterior angle of the given regular polygon.

The given regular polygon is a three-sided regular polygon, that is, it is an equilateral triangle.

∴ We can say that n = 3.

∴ The value of each interior angle of a regular polygon = {(n - 2)180°}/n.

or, The value of each interior angle of a regular polygon = {(3 - 2)180°}/3 = 180°/3 = 60°.

∴ The value of each exterior angle of a regular polygon = 360°/n.

or, The value of each exterior angle of a regular polygon = 360°/3 = 120°.

∴ The given regular polygon is an equilateral triangle.

The measure of one interior angle of it is 60°.

The measure of one exterior angle is 120°.

Answer: 7 minutes

Step-by-step explanation:

There is no n variable in the question, found the original question and the equations is: t = 2n – 3.

So, to answer this question we simply have to substitute n=5 in the equation given:

t = 2(5) – 3.

Solving for t(time)

t = 10-3 = 7 min.

It will take the customer 7 minutes to buy 5 coffees.

Step-by-step explanation:

perimeter is to add all sides

73m= 16+B+C

{ use algebra}

C is a, B is twice C, hence 2a

a+2a(+16)=73

3a=73-16= 57

3a=57, divide

a= 19

B=19×2= 38m

C=19m

C is 19m

Answer:

C = 19 m

Step-by-step explanation:

Side B is twice the length of Side C.

B = 2C -----------(I)

Perimeter = 73 m

A + B + C = 73

A + 2C + C = 73  {from (I)}

16 + 3C = 73

3C = 73 - 16

3C = 57

C = 57/3

C = 19 m

Answer:

A

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying

[tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]

[tex]\sqrt{12}[/tex] = [tex]\sqrt{4(3)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]

Thus

[tex]\sqrt{6}[/tex] + 2[tex]\sqrt{3}[/tex] + [tex]\sqrt{27}[/tex] - [tex]\sqrt{12}[/tex]

= [tex]\sqrt{6}[/tex] + 2[tex]\sqrt{3}[/tex] + 3[tex]\sqrt{3}[/tex] - 2[tex]\sqrt{3}[/tex] ← collect like terms

= 3[tex]\sqrt{3}[/tex] + [tex]\sqrt{6}[/tex] → A

The equivalent to the given expression is √6 + 3√3.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can simplify the given expression by combining like terms under the radicals:

√6 + 2√3 + √27 - √12

= √(23) + 2√3 + √(3³) - √(2²3)

= √2√3 + 2√3 + 3√3 - 2√3

= √2√3 + 3√3

= √(23) + 3√3

= √6 + 3√3

Therefore,

The equivalent to the given expression is √6 + 3√3.

[tex] \boxed{\sf \frac{3x - 11}{ {x}^{2} + 2x - 3}} [/tex]

Step-by-step explanation:

[tex] \sf \implies \frac{5}{x + 3} - \frac{2}{x - 1} \\ \\ \sf Put \: each \: term \: in \: \frac{5}{x + 3} - \frac{2}{x - 1} \: over \: the \: common \\ \sf denominator \:(x + 3)(x - 1) : \\ \sf \implies \frac{5(x - 1)}{(x - 1)(x + 3)} - \frac{2(x + 3)}{(x - 1)(x + 3)} \\ \\ \sf \frac{5(x - 1)}{(x - 1)(x + 3)} - \frac{2(x + 3)}{(x - 1)(x + 3)} = \frac{5(x - 1) - 2(x + 3)}{(x - 1)(x + 3)} : \\ \sf \implies \frac{5(x - 1) - 2(x + 3)}{(x - 1)(x + 3)} \\ \\ \sf 5(x - 1) = 5x - 5 : \\ \sf \implies \frac{ \boxed{ \sf 5x - 5} - 2(x + 3)}{(x - 1)(x + 3)} \\ \\ \sf - 2(x + 3) = - 2x - 6 : \\ \sf \implies \frac{5x - 5 + \boxed{ \sf - 2x - 6}}{(x - 1)(x + 3)} \\ \\ \sf Grouping \: like \: terms, \: 5x - 5 - 2x - 6 = \\ \sf (5x - 2x) + ( - 5 - 6) : \\ \sf \implies \frac{ \boxed{ \sf (5x - 2x) + ( - 5 - 6)}}{(x - 1)(x + 3)} \\ \\ \sf 5x - 2x = 3x : \\ \sf \implies \frac{ \boxed{ \sf 3x} + ( - 5 - 6)}{(x - 1)(x + 3)} \\ \\ \sf - 5 - 6 = - 11 : \\ \sf \implies \frac{3x + \boxed{ - 11}}{(x - 1)(x + 3)} [/tex]

Answer:

[tex]g(x) = \frac14x^2[/tex]

Step-by-step explanation:

Since f(x) and g(x) share the same top at (0,0), their difference is only a scale factor, so g(x) = ax² but we need to find a.

To find it, we use the given point of g, (2,1)

So g(2) = 1

meaning that

a·2² = 1

4a = 1

a = 1/4

Answer:

Answer:

75a + 90b ≤ 70000

a ≤ b

Step-by-step explanation:

Maple grove wants to include 2 types of maple trees .The 2 trees that are to be added cost $75 and $90 each. The total amount should not exceed $70000. And the people wants more of the $90 tree.  

Let

the number of the $75 tree = a

number of the $90 tree = b

The total cost of the $75 variety of maple tree = 75a

The total cost of the $90 variety of maple tree = 90b

And the cost of the trees shouldn't exceed $70000. Therefore,

75a + 90b ≤ 70000

Note the people needs more of the $90 tree, this means a ≤ b.

So, for the circle:
