Answer:

[tex]\Huge\boxed{76}[/tex]

Step-by-step explanation:

Hello There!

The first thing we want to do is find the proportional relationship between to two triangles

The smaller triangles longest side is 18

Given the longest side of the similar triangle we can divide the longest side of the preimage by the longest side of the similar triangle

So the proportional relationship would be

36/18 or 2

Our next step is to find the the sides of the similar triangle

To do so we multiply the sides of the preimage by 2 (because 2 is the proportional relationship between the two triangles)

12x2=24

8x2=16

and we already know that the longest side measures 36

Now we can find the perimeter by adding all of the side lengths

36+24+16 = 76

So we can conclude that the perimeter of the dilated image is 76

The perimeter of the dilated triangle is 81.

Step-by-step explanation:

Jamal has some counters in a bag.
36% of the counters are red
the rest of the counters are yellow
Jamal puts 50 blue counters into the bag.
Now 25% of the counters in the bag are blue.
Work out the number of yellow counters in the bag.
(3 marks)
​

Answers

Since he put 50 blue which form 25% then the total number of flags is 200 flag so the yellow have 39% of the flags which are 78 yellow flag

The number of yellow counters in the bag Jamal has got for this case is obtained being 96

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given that:

The bag initially had 36% of red counters and rest of the counters being yellow in color.Later was added 50 blue counters.The number of blue counter in the bag is 25% of all the counters in the bag.

Let the initial number of counters in the bag be 'x'

Then, 36% of x is:

[tex]\text{Number of red counters} = \dfrac{x}{100} \times 36 = 0.36 \times x[/tex]

Rest of them are yellow, so we get:

[tex]\text{Number of yellow counters} = x - \dfrac{x}{100} \times 36 = x(1-0.36) = 0.64 \times x[/tex]

Now, adding 50 blue counters make:

Total count of counters in bag = [tex]x + 50[/tex]

25% of this count is blue, and we know its 50. Thus, we get:
25% of (x+50) = 50

or

[tex]\dfrac{x+50}{100} \times 25 =50\\\\x+50 = 4 \times 50\\\\x = 200-50 = 150[/tex]

Thus, there were 150 coutners in the bag, initially.

The number of yellow counters is:

[tex]\text{Number of yellow counters} = 0.64 \times x = 0.64 \times 150 = 96[/tex]

Thus, the number of yellow counters in the bag Jamal has got for this case is obtained being 96

Find the area of this figure. Round your
answer to the nearest hundredth.
Use 3.14 to approximate a.
A = [?] m2
Notice that only half of the circle is included in the figure!

Answers

Answer:

51.63m^3

Step-by-step explanation:

The figure is made up of a rectangle, triangle and a semi circle

Area of the figure = Area of triangle + rectangle + semicircle

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 * 3 * 5

Area of the triangle = 15/2

Area of the triangle = 7.5m^3

Area of the rectangle = Length * Width

Area of the rectangle = 6 * 5

Area of the rectangle = 30m^2

Area of the semicircle = πr²/2

Area of the semicircle = π(3)²/2

Area of the semicircle = 3.14(9)/2

Area of the semicircle = 3.14 * 4.5

Area of the semicircle = 14.13m^2

The area = 30 + 14.13+7.5

Area of the figure = 51.63m^3

Find the value of x. Round your answer to the nearest tenth.

That's a question about the Pythagorean Theorem.

We use the Pythagorean Theorem to find the value of one side in a right triangle.

This theorem says that:

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

a is the hypotenuse (It's the opposite side the right angle).b and c are cathetus (They're the adjacent sides the right angle).

Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of x (the hypotenuse). Let's change this information in that formula.

[tex]a^2 = b^2 + c^2\\x^2 = 10^2 + 7^2\\x^2 = 100 + 49\\x^2 = 149\\x = \sqrt{149}[/tex]

Therefore, the value of x is [tex]\sqrt{149}[/tex].

I hope I've helped. :D

If ab = 9 and a² + b² = 81, then (a+b)² = ?​

Answers

Answer:

99

Step-by-step explanation:

Through some clever algebra, we can combine our first two equations using the fact that

[tex](a+b)^2=a^2+2ab+b^2[/tex]

We have the a² and the b² in the equation [tex]a^2+b^2=81[/tex], and we almost have a 2ab in the equation [tex]ab=9[/tex]. To get that 2ab, we can simply double both sides of the first equation to get [tex]2ab=18[/tex]. From there, we'll add the first two equations together, giving us the summed equation

[tex]a^2+b^2+2ab=81+18\\a^2+2ab+b^2=99[/tex]

And since [tex](a+b)^2=a^2+2ab+b^2[/tex], we can equivalently say that

[tex](a+b)^2=99[/tex]

Answer: Yw :^

Step-by-step explanation: Present: Ishaan = Christopher + 20       - Equation 1

1 years back: Ishaan-14 = 3(Christopher-14)    - Equation 2

 

Solve above equations:

 

I = 3c-42+14

I = 3c-24

I = c+20

 

2c-44 = 0

 

Christopher = 22  then from Equation 1

Ishaan = 22 + 20 = 42

m<KJL=22°

Answer:

BC = 54 unitsm∠KJL =  22°

Step-by-step explanation:

BD is the perpendicular bisector of AC because AD = DC and DB⊥AC, therefore AB = BC

6x = 9x - 279x - 6x = 273x = 27x = 9

BC = 9x - 27 = 9*9 - 27 = 81 - 27 = 54

-----------------------

JL is angle bisector of KJM, because KL = ML and  KL⊥JK & ML⊥JM, therefore

m∠KJL = m∠MJL4x + 6 = 3x + 104x - 3x = 10 - 6x = 4

m∠KJL = 4*4° + 6 = 22°
