Answer:

c=35 degrees

Step-by-step explanation:

Its a right angle triangle which is equal to 90 degrees

so 43 +12=55 degrees.

90-55=35 degrees

c=35 degrees

Step-by-step explanation:

Geometric mean = 7.3

Answer:

This is the isosceles right triangle as one of the angles is 45°.

The second leg is same as the first and the hypotenuse is √2 times the leg.

This is the 30°x60°x90° triangle and the ratio of sides is:

Since the hypotenuse is 16, the other sides are:

Geometric mean of two numbers is the square root of their product.

Correct choice is C

Answer:

129 m²

Step-by-step explanation:

Let's start by finding the areas of the triangles on the sides:

4×6÷2=12 (height times base divided by two)

Then we multiply by 2 as there are 2 of them

12×2=24

Then we find the areas of the rectangles:

5×7=35

35×3=105 (there are three)

Finally we add them:

105+24=129 m²

yeet this is a thicc problem...

6x - 14 + 3(2x-1) = 5 - 2(x-10)

first expand

6x - 14 + 6x -3 = 5 -2x-20

now put constants and variables on either sides of the thingamajig

6x+6x+2x= 5 - 20 + 3 + 14

14x = 2

x = 1/7

The value x = 3 makes the given equation true.

Important information:

The given equation can be written as:

[tex]6x-14+6x-3=5-2x+20[/tex]

[tex]12x-17=-2x+25[/tex]

Isolate the variable.

[tex]12x+2x=25+17[/tex]

[tex]14x=42[/tex]

[tex]x=\dfrac{42}{14}[/tex]

[tex]x=3[/tex]

Therefore, the required value of x is 3.

Answer:

3

Step-by-step explanation:

C(n) = 5n, 0 ≤ n ≤ 10       You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.

C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.

C(10) = 5(10)                 Input the value 10 as x.

C(10) = 50                    Simplified

Next,

C(n) = 4n + 5, n > 10      You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.

C(n) = 4n + 5, n > 10  ←  You can ignore the n>10 part.

C(12) = 4(12) + 5, n > 10  Input the value of 12 as x.

C(12) = 48 + 5                 Simplify

C(12) = 53    

Finally,

The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).

C(12) - C(10)

(53) - (50)                       Input the values of C(12) and C(10).

= 3                                  Simplify.

The answer is 3.

Answer:

Option D. {7 + i√71 / 20, 7 – i√71 / 20}

Step-by-step explanation:

10m² – 7m + 3 = 0

Using formula method, the solution to equation can be obtained as follow:

10m² – 7m + 3 = 0

Coefficient of m² (a) = 10

Coefficient of –7m (b) = –7

Constant (c) = 3

m = –b ±√(b² – 4ac) / 2a

= – –7 ±√((–7)² – 4 × 10 × 3) / 2 × 10

= 7 ±√(49 – 120) / 20

= 7 ±√(–71) / 20

Recall:

–17 = –1 × 17

Thus,

7 ±√(–71) / 20 = 7 ±√(–1 × 71) / 20

Recall:

√–1 = i

Thus,

7 ±√(–1 × 71) / 20 = 7 ± i√71 / 20

= 7 + i√71 / 20 or 7 – i√71 / 20

Therefore, the solutions to the equation are:

{7 + i√71 / 20, 7 – i√71 / 20}

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 6) and (x₂, y₂ ) = (- 1, 8) ← 2 ordered pairs from the table

m = [tex]\frac{8-6}{-1-1}[/tex] = [tex]\frac{2}{-2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute any ordered pair from the table into the partial equation

Using (1, 6 ) , then

6 = - 1 + c ⇒ c = 6 + 1 = 7

y = - x + 7 → B

Answer:

Option B

Step-by-step explanation:

Given quadratic equation is,

12a² + 9a + 7 = 0

By comparing this equation with standard quadratic equation,

hx² + kx + c = 0

h = 12, k = 9 and c = 7

By using quadratic formula,

a = [tex]\frac{-k\pm\sqrt{k^2-4hc}}{2h}[/tex]

  = [tex]\frac{-9\pm\sqrt{9^2-4(12)(7)}}{2(12)}[/tex]

  = [tex]\frac{-9\pm\sqrt{81-336}}{2(12)}[/tex]

  = [tex]\frac{-9\pm\sqrt{-255}}{24}[/tex]

  = [tex]\frac{-9\pm i\sqrt{255}}{24}[/tex]

a = [tex]\frac{-9+ i\sqrt{255}}{24},\frac{-9- i\sqrt{255}}{24}[/tex]

Therefore, Option B will be the correct option.

Answer:

11 marbles

Step-by-step explanation:

Let x = no. of marbles-Alex

3x = no. of marbles-Billie

3x - 9 = no. of marbles-Chris

x + 3x + 3x - 9 = 68

7x - 9 = 68

7x = 77

x = 11

Alex will have 11 marbles out of a total of 68 marbles.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Alex has some marbles. Billie has three times as many marbles are Alex.

Chris has 9 fewer marbles than Billie.

In total, they have 68 marbles.

Let x = no. of marbles-Alex

3x = no. of marbles-Billie

3x - 9 = no. of marbles-Chris

The number of marbles will be calculated as,

x + 3x + 3x - 9 = 68

7x - 9 = 68

7x = 77

x = 11

Hope this helps

Step-by-step explanation:

Answer:

x = 13

Step-by-step explanation:

(8x - 46) + (10x - 8) = 180

18x - 54 = 180

      +54    +54

18x = 234

/18     /18

x = 13

Check work:

8(13) - 46 = 10(13) - 8

8(13) - 46 = 58

10(13) - 8 = 122

58 + 122  = 180
