================================================

Part (f)

See the diagram that mentions this part. It's in a separate image.

The item can be anything really. I'm going to add a trampoline which is a square shown in purple. The square is rotated 45 degrees so it looks like a diamond shape. The rotation isn't necessary but I figured to spice things up compared to the other figures which were mostly squares or rectangles. If we split the purple square into 4 triangles, and apply the pythagorean theorem, then we can find the length of each side of the purple square to be roughly 2.828 cm.

Scaling things up, the trampoline in real life is 2*2.828 = 5.656 meters along each dimension.

With any square the angles are always 90 degrees.

Answer: M=7

Step-by-step explanation:

Isolate the variable by dividing each side by factors that dont contain the variable.

Answer:

the probability is 50% or 1/2 (equally likely and equally unlikely)

That is because it does not state the amount of socks inside the draw; meaning the answer has to be theoretical.

If the probability is the same, than it has to equal to 100

so we can conclude that 1/2 of the drawer is blue socks and 1/2 is white socks.

Answer:

sqrt( 17^2+ 25^2)

Step-by-step explanation:

Since this is a right triangle, we can use Pythagorean theorem

a^2+b^2 = c^2  where a and b are the sides and c is the hypotenuse

Taking the square root of each side

sqrt(a^2+b^2) = QR

sqrt( 17^2+ 25^2) = QR

Answer:

[tex] \small \sf A. \sqrt{25 {}^{2} + 17 {}^{2} } [/tex]

Step-by-step explanation:

Using pythagoras theorem

( Base) ² + ( Perpendicular) ² = (Hypotenuse) ²

( QS)² + ( RS)² = (OR )²

( 25 )² + ( 5 )² = OR²

Taking square root of each side.

[tex] \sqrt{25 {}^{2} + 17 {}^{2} } = \sqrt{OR}[/tex]

[tex] \sqrt{25 {}^{2} + 17 {}^{2} } = {OR}[/tex]

Answer:

[tex]1.8[/tex]

Step-by-step explanation:

Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:

[tex]T\propto \frac{1}{H}[/tex]

Convert 5 minutes to seconds:

[tex]5\cdot 60=300\:\mathrm{s}[/tex]

Therefore, from the initial data given (When H=6, T=90), the new time is [tex]\frac{300}{90}=3\frac{1}{3}[/tex] larger. Therefore, H must be [tex]3\frac{1}{3}[/tex] times smaller for them to be inversely proportional.

[tex]H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}[/tex]

Answer:

x > 1/6.

Step-by-step explanation:

–2(8x – 4) < 2x + 5

-16x + 8 < 2x + 5

-18x < -3

x > 1/6.

The solution to the inequality expression is x > 1/6

Given the inequality expression

–2(8x – 4) < 2x + 5

Expand the parenthesis

-16x + 8 < 2x + 5

Subtract 5 from both sides

-16x + 8 - 5 < 2x + 5 - 5

-16x + 3 < 2x

-16x - 2x < -3

-18x < -3

Divide both sides by -18

-18x/-18 > -3/-18

x > 1/6

Hence the solution to the inequality expression is x > 1/6

Step-by-step explanation:

since theyre mutliplied you can separate

(125 / 25) x (x^3 / x^4) x (y^5 / y^2)

when you divide exponents, they subtract

Dont be afraid of negative exponents

(125 / 25) x (x^-1 / 1) x ( y^3)

x^-1 = 1/x

solve for 125/25 and put together the fractions

Answer:

[tex]\frac{5y^3}{x^1}[/tex] or [tex]\frac{5y^3}{x}[/tex]

Step-by-step explanation:

125/25 = 5

x³ - x⁴ = x⁻¹

y⁵ - y² = y³

All together; 5x⁻¹y³

Since the answer has to be positive exponents, it would be;

[tex]\frac{5y^3}{x^1}[/tex]

Answer:

Sin31°= 11/x

x = 11/Sin31

x= 21.4. ( Nearest tenth).

Answer:

x ≈ 21.4

Step-by-step explanation:

Using the sine ratio in the right triangle

sin31° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )

x × sin31° = 11 ( divide both sides by sin31° )

x = [tex]\frac{11}{sin31}[/tex] ≈ 21.4 ( to the nearest tenth )

Answer:

30 baloons

Step-by-step explanation:

1. Remove the price of the banner from the total amount you can spend.  You should then end up with $90

2.  Divide 90 by 3, because each balloon costs $3.  You should end up with 30.

Answer:

30 balloons

Step-by-step explanation:

Cost of banner = $ 35

Remaining amount after paying for banner = 125 - 35 = $90

Number of balloons = Remaining amount ÷ cost of one balloon

= 90 ÷ 3

 = 30

Answer:

195

Step-by-step explanation:

create a proportion: # tests/time = # tests/time

cross-multiply to get:

3t = 585

t = 585/3 which equals 195

Answer:

5 1/3 > 5.3

Step-by-step explanation:

1/3 = 0.333... so 5 1/3 > 5.3 as 5 1/3 = 5.333...

The fraction 5 1/3 is greater than 5.3.

A number expressed as a quotient, in which a numerator is divided by a denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. A fraction represented with its quotient and remainder is a mixed fraction.

For the given situation,

The decimal number is 5.3.

The mixed fraction is 5 1/3.

First, convert this fraction to a decimal number to check which is greater.

[tex]5\frac{1}{3}=\frac{16}{3}[/tex]

⇒ [tex]5.33[/tex]

On comparing these two decimals 5.33 and 5.3, we can conclude that    5 1/3 is greater than 5.3.

Answer:

-12 + 6 -14

Step-by-step explanation:

Answer: 9√2

Step-by-step explanation:

The length of each side of the square is 109/25 units.

Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².

The length of the diagonal of the square in given figure is 9 units.

Suppose each side of square be x unit.

Apply Pythagoras theorem to obtain length of the side as follows,

x² + x² = 9²

=> 2x² = 81

=> x² = 81/2

=> x = 6.36

       = 636/100

       = 159/25

Hence, the value of x in the simplest radical form is 6.36 units.

Step-by-step explanation:

The number of ways we can choose three different numbers in order for a unique code for this case is 2730

A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total number of ways,

⇒ [tex]^{m} C_{k} =[/tex] m! / (m - k)! k!

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, total number of choices in that case would be:

⇒ [tex]^{m} P_{k} =[/tex] m! / (m - k)!

This is called permutation of k items chosen out of m items (all distinct).

Given that:

The considered lock as a 3 number code

There are 15 numbers available.

None of the number can repeat.

In a lock, the order of the way numbers are arranged matters.

Because of no repetition allowed, we can simulate this situation as:

The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.

And we have:

The number of ways we can choose 3 numbers out of 15 numbers with order is,

⇒  [tex]^{m} P_{k} =[/tex] m! / (m - k)!

⇒  [tex]^{15} P_{3} =[/tex] 15! / (15 - 3)!

            = 15! / 12!

            = 2730

Thus, The number of ways we can choose three different numbers in order for a unique code for this case is 2730

Step-by-step explanation:

angles of a Tringle Addup to 180

let <2=x

61+58+x=180

x=180-61-58

x= 61°

now we know that the triangle was an isocelies triangle

<2=61°

But <2 and <4are on a straight line

therefore the sum of the angles are 180

<2+<4=180°

61°+<4=180°

<4=180°-61°

<4=119°
