Answer:

[tex]\huge\boxed{\sf x = 16}[/tex]

Step-by-step explanation:

Using Pythagoras Theorem since it is a right angled triangle.

Where,

Base = 12

Perpendicular = x

Hypotenuse = 20

[tex](Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]

[tex](20)^2=(12)^2+x^2\\\\400 = 144 + x^2\\\\Subtract \ 144 \ to \ both \ sides\\\\400-144=x^2\\\\256 =x^2\\\\Take\ Sq. \ root\ on \ both \ sides\\\\\sqrt{256} =x^2\\\\16 = x\\\\x = 16\\\\\rule[225]{225}{2}[/tex]

Answer:

Submarine submerges at the rate of =5m/min

descend starts from = 20m

submarine have to reach = -250m

Distance between above sea level to below sea level = 250 + 20 = 270m

time taken to reach 270 m = 270/5= 54 minutes

Answer:

mn(5mn² + 9) ;

2mn(1 - 1/2mn²)

Step-by-step explanation:

Given:

5m²n³ +9mn

(8mn - 4m²n³ ÷ 4)​

5m²n³ + 9mn

mn(5mn² + 9)

(8mn - 4m²n³ ÷ 4)​

8mn/ 4 - 4m²n³ / 4

2mn - m²n³

2mn(1 - 1/2mn²)

3x-2y+4z-x+5y+3x-2y+4z-x+z

First, reorder(I put the like terms in parenthesis to help you see the work better).

(3x+3x-x-x)+(5y-2y-2y)+(4z+4z+z)

Now, we add/subtract like terms.

(6x-2x)+(5y-4y)+(8z+z)

Lastly, we combine.

4x+y+9z

I got you bro!

Answer:

{x,y} = {4-1}

You might be wondering how I got this, well here are the steps:

System of Linear Equations entered :

  [1]    2x + y = 7

  [2]    x - 2y = 6

Graphic Representation of the Equations :

   y + 2x = 7        -2y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    x = 2y + 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y+6) + y = 7

  [1]    5y = -5

// Solve equation [1] for the variable  y  

  [1]    5y = - 5

  [1]    y = - 1

// By now we know this much :

   x = 2y+6

   y = -1

// Use the  y  value to solve for  x  

   x = 2(-1)+6 = 4

Solution :

{x,y} = {4,-1}

I hope this has helped you and have a wonderful day!

Answer:

11

Step-by-step explanation:

square of 44 + 77

1st step = go with the number that is inside the square

that will 44+77 = 121

now using the square root , you may think about which number multiple by himself give you 121

11×11 =121

so square root of 121 = 11

[tex] \sf Q) \sqrt{44 + 77} = {?} [/tex]

[tex] \sf \implies \sqrt{44 + 77} [/tex]

[tex] \sf \implies \sqrt{121} [/tex]

[tex] \sf \implies 11[/tex] is the required answer.

Answer: MN = 8.5

Step-by-step explanation:

Form it into a right triangle with MN being the hypotenuse (side opposite the right angle)

To make this a right triangle, plot a point at (8,-2) and connect the sides. The lengths of the legs that form the right angle are both 6 units. Use the Pythagorean theorem to solve for length of MN. a^2+b^2=c^2. (a and b are the legs that form the right angle and c is the hypotenuse)

6^2+6^2=c^2

36+36=c^2

72= c^2

8.48528137 = c.

Question says to round to nearest tenth of a unit

8.5 = c (line MN)

The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.

Then the probability of the oranges that weigh 5 ounces is given as,

p = 2/25

Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,

E(x) = 700 x 2 / 25

E(x) = 28 x 2

E(x) = 56

The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

Answer:

Bru I’m in ur class and it’s The median

Step-by-step explanation:

It’s the median

Out of all the options listed, the only one that does not show variation (spread) is the median.

The median is simply used to show the medium value of a data set. It cannot be used to tell the variation because it does not take into account all the values but rather the middle one alone.

The other options are wrong because:

In conclusion, only the median does not help with finding the variation of a dataset.

Answer:

The area of the rectangle in terms of x :

=> x1=−2/5, x2= 4/3

Step-by-step explanation:

Answer:

4y^{2}+3y  

Step-by-step explanation:

First you need to distribute the values.  

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials  

You Should get  

8y^{2}+6y  

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2  

Doing this you will get  

4y^{2}+3y
