Answer:

119cm

Step-by-step explanation:

add 37 and 24 you get 61 and the size of a triangle no matter what is going to be 180 so then subtract 180 from 61 and get 119.

Answer:

Step-by-step explanation:

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have

x = (mx₂ + nx₁) / (m + n)

y = (my₂ + ny₁) / (m + n)

The two endpoints are (-6, -2) and (8, -9). And m: n = 2: 5. Then the value of the x-coordinate is calculated as,

x = (2 · 8 + 5 · -6) / (2 + 5)

x = (16 - 30) / (7)

x = - 14 / 7

x = - 2

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the  cholesterol level is decreased after particular time period,

Hence, it is an uncontrolled experiment.

Thus, option B is correct.

Given:

The graph of a polynomial.

To find:

The number of roots of the polynomial lie between x = -4 and x = 3.

Solution:

From the given graph it is clear that the graph is a downward U-shaped curve. It means the given graph represents a quadratic polynomial.

The graph of the polynomial is below the x-axis immediate before x=-2 and above the x-axis immediate after x=-2. It means the graph intersect the x-axis at x=-2.

The graph of the polynomial is above the x-axis immediate before x=2 and below the x-axis immediate after x=2. It means the graph intersect the x-axis at x=2.

Since the graph of the polynomial divides the x-axis two times between x = -4 and x = 3, therefore the two roots of the polynomial lie between x = -4 and x = 3.

Answer:

parallelogram is a special type of rectangle, a square. A square is one of the most basic geometric shape

Answer:

320 cm² or 264 cm²

Step-by-step explanation:

first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²

the 2 square faces will be either 8 x 8 or 6 x 6.

If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²

If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²

x = 19 cm

Step-by-step explanation:

3+3+2+5+6 = 19

Answer:

Length & Breadth could be : 4 meters , 5 meters

Step-by-step explanation:

Border, ie perimeter measurement of Rectangle = 2 ( Length + Breadth )

So, 2 (Length + Breadth) = 18

Length + Breadth = 18 / 2

Length + Breadth  = 9

So, sum of length & breadth must be = 9.

(L, B) = (2,5) ; (2,8) ; (2,9) and (3,5) ; (3,8) ; (3,9) don't satisfy this condition. (4,5) ; (4,8) also don't.

(L, B) = (4,5) satisfy it. As sum 4 + 5 = 9.

Answer:

Primer hermano = x = 16 años

Segundo hermano = y = 9 años

Step-by-step explanation:

Representemos sus edades como:

Primer hermano = x

Segundo hermano = y

Dos hermanos tienen 7 años de diferencia

= x - y = 7

x = 7 + y

La suma de los cuadrados de sus edades es 337.

x² + y² = 337

Sustituyendo

(7 + y) ² + y² = 337

Cuadrado

(7 + y) (7 + y) + y² = 337

49 + 7y + 7y + y² + y² - 337 = 0

2y² + 14y - 288 = 0

Paso 1: Factoriza el lado izquierdo de la ecuación.

2 (y − 9) (y + 16) = 0

Paso 2: Iguala los factores a 0.

y - 9 = 0 o y + 16 = 0

y = 9 o y = −16

Por tanto, y = 9 años

x = 7 + y

x = 7 + 9

x = 16 años

Primer hermano = x = 16 años

Segundo hermano = y = 9 años

Step-by-step explanation:

The area of a triangle is base times height times 1/2. The base times the height of that triangle is 66. 66 times 1/2 is 33. So, the correct answer is C.

Answer:

66 cm

Step-by-step explanation

11cm x 6 cm= 66cm

Answer:

yn +y -xn

Step-by-step explanation:

Mean= sum of numbers ÷number of numbers

x= sum of n numbers ÷n

Multiply both sides by n:

xn= sum of n numbers

sum of n numbers= xn -----(1)

Let the number added be a.

After a has been added,

y= (sum of n numbers +a) ÷(n+1)

Multiply both sides by (n +1):

y(n +1)= sum of n numbers +a

sum of n numbers= y(n +1) -a -----(2)

Substitute (1) into (2):

xn= y(n +1) -a

Expand:

xn= yn +y -a

a= yn +y -xn

Let's check!

Let the numbers be 1, 2, 3 and 4.

mean, x= 10 ÷4= 2.5

n= 4

Let the new number added, a, be 7.

a= 7

mean, y= 17 ÷5= 3.4

a= yn +y -xn

a= 3.4(4) +3.4 -2.5(4)

a= 7

Thus, the expression is true.

Given

The above steps

Required

Which is not part of the process

We have:

[tex]5(2x-8)= 20[/tex]

[tex]10x - 40 = 20[/tex]

[tex]10x - 40+ 40 = 20 + 40[/tex]

[tex]10x = 60[/tex]

[tex]\frac{10x}{10} = \frac{60}{10}[/tex]

[tex]x = 6[/tex]

Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.

Other properties are:

[tex]5(2x-8)= 20[/tex] ---- Distributive

[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms

[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable

When theres a triangle with a right angle you need to make in a rectangle and divide it by 2

Answer:

In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.

Step-by-step explanation:

The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.
