Afla cate procente reprezinta numarul a din numarul b daca a si b sunt invers proportionale cu numerele 12 si 15

Answers

Answer 1

Răspuns:

125%

Explicație pas cu pas:

a și B sunt invers proporționale cu numerele 12 și 15

Proporționalitate inversă:

a = k / y

Prin urmare ;

a = k / 12 - - - (1)

b = k / 15 - - - (2)

Procent care reprezintă a de la b

a = 100%

b = x

k / 12 = 1

k / 15 = x

Înmulțirea încrucișată:

x * k / 12 = k / 15

x = k / 12 ÷ k / 15

x = k / 12 * 15 / k

x = 15/12

x = 1,25

1,25 * 100% = 125%

Step-by-step explanation:

Essentially, we must have e^(-0.00012h) = 0.65 since 0.65 = 65%

Taking natural log of both sides, we get

-0.00012h = -0.430782916

0.00012h = 0.430782916

the first player to the tenth player without spilling within the allotted time. After the task, the team captain measured
the water collected using a measuring cup. Team Narra collected 1.402 liters while Team Mahogany collected 1.045
liters of water. Which team got more water?
Solution:​

Answers

Answer:

Team Nara collected more water

1.402 > 1.045

so team nara wins

Team Narra is collected more amount of water than Team Mahogany and this can be determined by using the given data.

Given :

Team Narra and Team Mahogany underwent a water challenge.Their task was to transfer the water in a cup from  the first player to the tenth player without spilling within the allotted time.Team Narra collected 1.402 liters while Team Mahogany collected 1.045  liters of water.

The following steps can be used to determine which team collected more amount of water in a cup:

Step 1 - Remember that the amount of water collected by Team Narra is 1.402 liters.

Step 2 - Also remember that the amount of water collected by Team Mahogany is 1.045 liters.

Step 3 - Now, compare both quantities of water.

1.045 < 1.402

So, according to the given data Team Narra is collected more amount of water than Team Mahogany.

Solve for x. Then find the side lengths of the triangle. If needed, round to the nearest tenth of a foot.
40 ft
Bx ft
6x ft
side lengths =
ft and

Answers

Answer:

The side lengths are 17.9 feet and 35.8 feet

Step-by-step explanation:

Given lengths are;

40 feet, 3x feet and 6x feet

As the given triangle is right angled,

a = 3x, b = 6x and c = 40

Using Pythagorean theorem;

[tex]a^2+b^2=c^2\\(3x)^2+(6x)^2=(40)^2\\9x^2+36x^2=1600\\45x^2=1600\\[/tex]Dividing both sides by 45

[tex]\frac{45x^2}{45}=\frac{1600}{45}\\x^2=35.55[/tex]

Taking square root on both sides

[tex]\sqrt{x^2}=\sqrt{35.55}\\x=5.96[/tex]

Side lengths = 3x = 3(5.96) = 17.9 feet

and

6x = 6(5.96) = 35.8 feet

Hence,

The side lengths are 17.9 feet and 35.8 feet

Answer: x= 8

Step-by-step explanation:

According to the converse of basic proportionality theorem,

If in ΔABC , DE is a line drawn from AB to AC such that [tex]\dfrac{AD}{DB}=\dfrac{AE}{EB}[/tex]

then, DE is parallel to the third side BC.

Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have

[tex]\dfrac{LO}{OJ}=\dfrac{LN}{NK}\\\\\Rightarrow \dfrac{x-4}{x}=\dfrac{x-3}{x+2}\\\\\Rightarrow\ (x-4)(x+2)=x(x-3)\\\\\Rightarrow\ x^2-2x-8=x^2-3x\\\\\Rightarrow\ -2x+3x=8\\\\\Rightarrow\ x=8[/tex]

Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.
