Answer:

36.43m

Step-by-step explanation:

Let the wingspan of the real aeroplane = x

The scale of the model is 4 cm to 15 m.

= 4: 15 = 4/15.

Sunita's model has a wingspan of 17cm.

Hence:

4cm/15m = 17cm/xm

Cross Multiply

4x = 15 × 17

4x = 255

x = 255/4

x = 36.428571429 m

Approximately = 36.43 m

Therefore, the wingspan of the real aeroplane is 36.43m

Step-by-step explanation:

George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft. And then he continues on into making ten pieces that all are 6ft long before loading them onto his truck.

By looking at the different pieces of wood we can see that the following holds true.

60=30+30=6+6+6+6+6+6+6+6+6+6

This is called the reflexive property of equality and tells us that any quantity is equal to itself

a=a

We can also use this example with the pieces of wood to explain the symmetric property of equality. This property states that if quantity a equals quantity b, then b equals a.

ifa=b,thenb=a

Or if we use our example

if60=30+30,then30+30=60

Another property that can be explained by this is the transitive property of equality. It tells us that if a quantity a equals quantity b, and b equals the quantity, c, then a and c are equal as well.

ifa=bandb=c,thena=c

Or in the numbers taken from the oak tree example

if60=30+30

and30+30=6+6+6+6+6+6+6+6+6+6

then60=6+6+6+6+6+6+6+6+6+6

Since we know that 30 + 30 = 20 + 40 and that 30 + 30 = 60 we can substitute 30 + 30 for 20 + 40 and get 60 = 20 + 40. This is called the substitution property of equality.

If a = b, then a can be substituted for b in any expression.George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft.

Answer:

1) Slope: 3; y-intercept: -7

2) Slope: 2/3; y-intercept: 1

Step-by-step explanation:

y = mx + b; m is slope and b is y-intercept

1. y = 3x - 7

The equation is already in slope-intercept form, so you can find the slope and intercept.

Slope: 3

y-intercept: -7

2. y - 1 = 2/3x

For this one, you have to convert this into slope-intercept form (solving for y)

y - 1 = 2/3x

Add 1 to both sides

y - 1 + 1 = 2/3x + 1

y = 2/3x + 1

Now that the equation is in slope-intercept form, you can get the slope and y-intercept.

Slope: 2/3

y-intercept: 1

Answer:

1) y = - 3 and x = 3

Answer:

[tex]c = 41[/tex]

Step-by-step explanation:

[tex] {c}^{2} = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

[tex]c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

[tex]c = \sqrt{ {9}^{2} + {40}^{2} } [/tex]

[tex]c = \sqrt{81 + 1600} [/tex]

[tex]c = \sqrt{1681} [/tex]

Answer:

$40.25

Step-by-step explanation:

15% = 0.15, so multiply 35 * 0.15 = 5.25 to get the tip.

Since the answer is asking for both the tip and the cost, add 35 + 5.25, which gives the answer $40.25

Answer:

Step-by-step explanation:

4 kings in a standard 52 card deck. Just find the fraction of 4/52 and then you will be able to find the percent, decimal and of course, fraction.

Answer:

Here are all 52 cards

A♥ 2♥ 3♥ 4♥ 5♥ 6♥ 7♥ 8♥ 9♥ 10♥ J♥ Q♥ K♥

A♦ 2♦ 3♦ 4♦ 5♦ 6♦ 7♦ 8♦ 9♦ 10♦ J♦ Q♦ K♦

A♠ 2♠ 3♠ 4♠ 5♠ 6♠ 7♠ 8♠ 9♠ 10♠ J♠ Q♠ K♠

A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣

Here are all the cards that are either a club or a 5:

5♥

5♦

5♠

A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣

Count them. There are 16.

So the probability is 16 out of 52 or 16/52 which reduces to 4/13.

Step-by-step explanation:

Step 1: figure out the total number of cards you might pull.

Write down all the possible cards and mark the ones that you would pull out (in our case we’ve been asked the probability of a club or a seven so we’re going to mark all the clubs and all the sevens):

hearts: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

clubs: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

spades: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

diamonds: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

This totals 16 cards. *

Step 2: Count the total number of cards in the deck(s). We have one deck, so the total = 52

Step 3: Write the answer as a fraction. Divide step 3 by Step 4:

16 / 52

Answer:

C) 5/3

Step-by-step explanation:

The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles

This gets you 5/3

So, the correct answer is C) 5/3

Answer:

5/3

Step-by-step explanation:

This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.

Answer:

[tex]\sqrt{2n^{2}}[/tex]

You have the side lengths of the two legs, n and n.

Then, using the pythagorean theorem you have to find the length of the third side:

[tex]a^2 + b^2 = c^2\\n^2 + n^2 = c^2\\2n^2 = c ^ 2\\\sqrt{2n^2} = c[/tex]

where c is the third side

Answer:

Angle 13 equal 90 and Angle 12 equal 45

Step-by-step explanation:

This is a square so all of the corner angles and the diagonals angles measure 90 degrees. A square also forms 4 congruent isoceles triangles or technically 45-45-90 triangles. So that means the following angles measure 45 degrees since they share a point

Angle 5,6,7,8,9,10,11,12. So the measure of 12 is 90 degrees.

To find the measure of 13, in a square diagonals bisect each other and form perpendicular lines so that means every angle in the middle of the square measure 90 degrees.

Using that

Angle 13,15,16 and R measure 90 degrees so Angle 13 equal 90.

Answer:

[tex]\% Percent = 75 \%[/tex]

Step-by-step explanation:

Given

[tex]Painters = 32[/tex]

[tex]Interior\ Painters = 24[/tex]

Required

Determine the percentage of the interior painters

This percentage is calculated as:

[tex]\% Percent = \frac{Interior\ Painters}{Painters} * 100\%[/tex]

This gives:

[tex]\% Percent = \frac{24}{32} * 100\%[/tex]

[tex]\% Percent = \frac{24* 100\%}{32}[/tex]

[tex]\% Percent = \frac{2400\%}{32}[/tex]

[tex]\% Percent = 75 \%[/tex]

75% are painting the interiors

Step-by-step explanation:

Answer:

x = 60°, y = 30°

Step-by-step explanation:

The sum of the triangle angles is always 180°

Therefore 90° + x + y = 180°

It is also known that x = 2y

// combine the given value of x into the previous expression

90° + 2y + y = 180°

2y + y = 180° - 90°

3y = 90°

// divide both sides by 3

y = 30°

// then combine the given value of y into the expression x = 2y

x = 2 * 30°

x = 60°
