Answer:

8 meters

Step-by-step explanation:

Given that:

Height of person = 2metres

Length of person's shadow = 6 meters

Height of flagpole =?

Length of flagpole shadow = 24 meters

Height of person = length of person's shadow

Height of flagpole = length of person's shadow

2 = 6

x = 24

Cross multiply

6x = 48

x = 48 / 6

x = 8 meters

Answer:

yes the cost is proportional to the number of tickets

Step-by-step explanation:

for each 1 ticket added, it is $12 more

you can graph it by using the equation y=12x where x is the amount of tickets and the y-intercept is (0,0)

The amount Archie has to pay for his share of the cost is £605

The costs of the holiday will be shared equally between the 4 friends.

These are:

The 4 of them will share the total cost equally. This means Archie paid the same amount with his friends.

Therefore, the amount Archie have to pay for his share of the costs can be calculated as follows:

total cost = 1360 + 850 + 210

total cost = £2420

Amount Archie paid = 2420 / 4

Amount Archie paid = £605

Therefore, the amount Archie has to pay for his share of the cost is £605

The Inequality Equation =

22 + 9x ≤ 58

The number of T -shirts Debbie can buy is at most 4 T-shirts

Step-by-step explanation:

Let the number of T shirts Debbie can buy be represented as x

We are told in the question: Debbie has at most $58 to spend on clothes.

This means she would not exceed $58. She would be spending less than or equal to $58

The Inequality Equation =

$22 + $9 × x ≤ $58

22 + 9x ≤ 58

Solving the Inequality Equation above:

22 + 9x ≤ 58

9x ≤ 58 - 22

9x ≤ 36

x ≤ 36/9

x ≤ 4 shirts

The number of T -shirts Debbie can buy is at most 4 T-shirts

Answer:

The number is 3

Step-by-step explanation:

Ok, first thing's first: we need to make the words into an actual equation.

since it just says a number I'll use x

3 times x + 4 = 13

3x +4 =13

Now that we have our equation, we can solve for x

3x + 4 = 13

     -4      -4

3x = 9

I subtracted 4 on both sides to get rid of the 4 and move it to the other side of the equation, so we can try to get x by itself.

3x =9

/3     /3

x = 3

I divided both sides by 3 to get rid of the 3 that's being multiplied by x

Now we have our number : x = 3

I hope this helps :)

Answer:

  acute scalene triangle

Step-by-step explanation:

The largest angle is acute, and all sides are different lengths. The triangle is an acute scalene triangle.

____

The magnitudes of the coordinate differences are ...

  WX = (7, 5), XY = (2, 7), WY = (9, 2)

The two sides that are closest in length are ...

  WX = √(49+25) = √74

  WY = √(81 +4) = √85

Obviously, these are different lengths.

You can get a clue by comparing the numbers whose squares you are adding:

  7^2 +5^2 > 7^2 +2^2 . . . . . WX > XY

  9^2 +2^2 > 7^2 +2^2 . . . . WY > XY

so, the only question is relation between WX and WY. We note that the length of WX is less than one of the coordinate differences of WY, so we know WY is the longest. (√74 < 9)

We can tell from the graph that angle X (opposite longest side WY) is an acute angle, so the triangle is acute.

Answer:

1+3+2+2=8

Step-by-step explanation:

Answer:

1/3+3+4(1/2)+2/3 = ♥♥♥♥6♥♥♥♥

Step-by-step explanation:

Lets denote the numbers x and y:

The sum of two numbers 94 → x + y = 94

Their difference is 12 → x - y = 12

We have:

x + y = 94

x - y = 12

----------------  Add both equations

2x = 106

x = 106/2

x = 53

Using first equation:

x + y = 94

53 + y = 94

y = 94 - 53

y = 41

A/ The numbers are 53 and 41.

Answer:

B

Step-by-step explanation:

∠ 2 and ∠ 3 are a linear pair and sum to 180°

∠ 2 + ∠ 3 = 180 , that is

9x + 7 + 5x + 5 = 180

14x + 12 = 180 ( subtract 12 from both sides )

14x = 168 ( divide both sides by 14 )

x = 12

Then

∠ 3 = 5x + 5 = 5(12) + 5 = 60 + 5 = 65°

∠ 3 and ∠ 1 are vertically opposite angles and are congruent , so

∠ 1 = 65°

n= number of times the interest is compounded per year (1)

t= time (7 years)

Answer:

£6053.29 to the nearest penny.

Step-by-step explanation:

Amount after 7 years = 4600(1 + 0.04)^7

Answer:

No. Jami can mow more than her advertisement states

Step-by-step explanation:

Because she can mow 1/6 of an acre in 6 minutes, and an hour is 60 minutes long, we know that she can mow up to ten times that in one hour. Think about it this way. How many times does six minutes go into 60? 10. So Jami can mow 1/6 of an acre up to 10 times in one hour. This means that in an hour Jami can mow 10/6, or 1 and 2/3 of an acre in an hour. Thus, her advertisement is understating how quickly she can mow.

The length of the hypotenuse is 13.

A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

According to the question ,

Given that ,  legs is 5 inches and 12 inches

how to find hypotenuse :    

we know ,  c^{2} = a^{2} + b^{2}    

⇒ c^{2}= 5^{2} + 12^{2}    

⇒ c^{2} = 25 + 144    

⇒ c = \sqrt{169}    

⇒ c = 13

The length of the hypotenuse is 13.

Correct option is (b) 13 inches .

Answer:

4

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The weight of the weight lighting bar = the initial value/y-intercept (b) = 45

Amount of weight = x

Total amount of weight = y

The rate of change (m) = 1

Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b

Thus:

y = (1)x + 45

y = x + 45

The correct option is c

Answer:

a) -9, -10, -11

b)24, 36, 54

c)-10, 20, -40

Step-by-step explanation:

-8 - 1 = -9

-9 - 1 = -10

-10 - 1 = -11

a2 = 16 * 3/2 = 24

a3 = 24 * 3/2 = 36

a4 = 36 * 3/2 = 54

f(2) = 5 * -2 = -10

f(3) = -10 * -2 = 20

f(4) = 20 * -2 = -40

The next three terms of each geometric sequence  are;

a) -9, -10, -11

b)24, 36, 54

c)-10, 20, -40

There are three parameters which differentiate between which geometric sequence we're talking about.

The first parameter is the initial value of the sequence.

The second parameter is the quantity by which we multiply previous term to get the next term.

a) The common difference is;

-8 - 1 = -9

b) The common difference is;

-9 - 1 = -10

c) The common difference is;

-10 - 1 = -11

a2 = 16 * 3/2 = 24

a3 = 24 * 3/2 = 36

a4 = 36 * 3/2 = 54

Therefore, the next terms are;

f(2) = 5 * -2 = -10

f(3) = -10 * -2 = 20

f(4) = 20 * -2 = -40

Answer:

Step-by-step explanation:

2 (9n-1)+7(n+6)= -60

18n-2 +7n + 42 = -60

25n + 40 = -60

25n = -100

n = -4

Answer:

n = - 4

Step-by-step explanation:

2 ( 9n - 1 ) + 7 ( n + 6 ) = - 60

Solve the brackets.

18n - 2 + 7n + 42 = - 60

Combine like terms.

25n + 40 = - 60

Subtract 40 from both sides.

25n = - 60 - 40

25n = - 100

Subtract 25 from both sides.

n = -4

The two triangles are symmetrically the same the only difference is they are opposite Intersecting at C.

Angle DCE and BCA intersect from the triangles which both form a similar angle let's assume are 60 degrees.

Therefore, Angle ACE and BCD are 120 degrees.

Therefore all sides from both triangles correspond to be both equal, for example, BA = ED, AC = DC, BC = EC

C is the midpoint of AD and BE therefore AC = CD and BC = CE.

The angles too are equally corresponding such as,

Angle ABC = DEC , CAB = CDE and BCA = ECD
