Answer:

∠ B = 65°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for B, that is

∠ B = 180° - (78 + 37)° = 180° - 115° = 65°

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.75x+3=6(x−3)

0.75x+3=(6)(x)+(6)(−3)(Distribute)

0.75x+3=6x+−18

0.75x+3=6x−18

Step 2: Subtract 6x from both sides.

0.75x+3−6x=6x−18−6x

−5.25x+3=−18

Step 3: Subtract 3 from both sides.

−5.25x+3−3=−18−3

−5.25x=−21

Step 4: Divide both sides by -5.25.

−5.25x/-5.25    =    -21/-5.25

Answer: x=4

The value of x from the given equation is 4.

The given equation is 0.75x + 3 = 6 (x - 3).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solve for x as follows:

0.75x + 3 = 6x - 18

⇒ 6x-0.75x = 3+18

⇒ 5.25x=21

⇒ x=21/5.25

⇒ x=4

Therefore, the value of x from the given equation is 4.

Answer:

[tex]V = 113.04m^3[/tex] --- Standard Model

[tex]Diameter = 15m[/tex] --- Larger Tank

Step-by-step explanation:

Given

Standard Model

[tex]Diameter = 6m[/tex]

Larger Tank

Diameter = 2.5 * Standard Model

Solving (a): Volume of Standard Model.

The tank is spherical; so, the volume (V) is as follows

[tex]V = \frac{4}{3}\pi r^3[/tex]

Where

[tex]r = \frac{1}{2}Diameter[/tex]

[tex]r = \frac{1}{2} * 6m[/tex]

[tex]r = 3m[/tex]

So:

[tex]V = \frac{4}{3}\pi r^3[/tex]

[tex]V = \frac{4}{3} * \pi * 3^3[/tex]

[tex]V = \frac{4}{3} * \pi * 27[/tex]

[tex]V = 4 * \pi * 9[/tex]

[tex]V = 4 * 9* \pi[/tex]

[tex]V = 36* \pi[/tex]

Take [tex]\pi[/tex] as 3.14

[tex]V = 36 * 3.14[/tex]

[tex]V = 113.04m^3[/tex]

Solving (b): Diameter of the larger tank

Diameter = 2.5 * Standard Model

[tex]Diameter = 2.5 * 6m[/tex]

[tex]Diameter = 15m[/tex]

Answer:

diameter =8.1

Step-by-step explanation:

The graph of g(x) is steeper than the graph of f(x). Then the correct option is A.

Functions are found all across mathematics and are required for the creation of complex relationships.

The graphs of f(x) = x and g(x) = f(5x).

Then the g(x) can be written as

g(x) = 5x

Then the slope of g(x) is more than the slope of f(x).

The graph of g(x) is steeper than the graph of f(x).

Then the correct option is A.

Answer:

  3x -4y = -9

Step-by-step explanation:

Multiply by 4 to clear the fraction.

  4(y -6) = 3(x -5)

Subtract the left-side term to get variables on the same side, with a positive x-coefficient.

  0 = 3(x -5) -4(y -6)

Eliminate parentheses and collect terms.

  0 = 3x -15 -4y +24

  0 = 3x -4y +9

Subtract 9 and swap sides to get standard form.

  3x -4y = -9

_____

Standard form is ...

  ax +by = c

where a ≥ 0, and a, b, c are mutually prime integers. If a=0, then b > 0.

The attached graph shows the equations give the same line. The original line is shown dotted so that you can see they overlap.

Step-by-step explanation:

Case 1 : |x| > a, => x > a or x < -a

Case 2 : |x| < a, => -a < x < a

Since this question follows Case 1, we will have an "or" inequality.

Answer:

n = 2.5 or n = (5/2)

Step-by-step explanation:

(2n+4) +6 = -9 + 4(2n+1)

first distribute the 4 to the (2n+1)

(2n+4) +6 = -9 + (8n+4)

then add 9 to both sides to cancel out the -9 on the right side

(2n+4) +15 = (8n+4)

next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract

15 = 6n

then divide 15 by 6 to get your final answer

n = 2.5

or

n = (5/2)

Step-by-step explanation:

Y intercept is 500 because she is starting off with $500 each month

slope is 75 because she gets $75 more every time she sells one

start at (0,500) then plot a point at (1,575) then (2,650) increasing by 75 every time x increases by 1

If you start at (0,500) you can move backwards going to (-1,425) to (-2,350) decreasing by 75 as you move backwards

the equation is y=75x+500

table: -3    275  

        -2     350

        -1     425

         0     500

Step-by-step explanation:

Volume of the square prism = Base  area * Height

Since the base is a square;

Base area = s²

s is the side length of the square

Given s= 13 inches,

Base area = 13²

Base area = 169in²

If he wants the height 6 inches longer than the width and the length, then the height will be:

Height = 13 + 6 = 18 inches

Get the volume

Volume of the square prism = 169in² * 18in

Volume of the square prism = 3042in³
