Answer:   [A]:  " 78 °  " .

_______

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

So, given m∠F & m∠G are supplementary angles:
 and given m∠F = (4x + 22) and:  m∠G = (6x + 18) ;

 Find m∠F ; which equals (4x + 22).

_______
So, add the 2 (two) supplementary angles;

set them as "equal to 180" ;

solve for x ;

then: plug that x  value into:
     (4x + 22) ; which is the m∠F ;

_______
 4x + 22 + 6x + 18 = 180 ;  

On the 'right-hand side of the equation" ;

 "combine the like terms" :
    + 4x + 6x = + 10x ;

    + 22 + 18 = 40 ;

Then rewrite the equation:
   10x + 40 = 180 ;

_______
Now:
Method 1):
 Subtract 40 from Each Side of the equation:
   10x + 40 − 40 = 180 − 40 ;
     to get:  10x = 140 ;  

  Now:  Divide Each Side of the equation by 10 ;  to isolate x on one side of the equation; & to solve for x ;
     10x / 10 = 140 / 10 ; to get:  " x = 14 " ;

Method 2):
  When we have:  10x + 40 = 180 ;

    Divide the entire equation (i.e. Each Side of the equation) by 10 ;

   to get rid of the "zeros" :

        (10x + 40) / 10 = (180)/10 ;

    to get:
    (10x/10) + (40/10) = (180/10);

     →  x  + 4 = 18 ;

     Subtract 4 from Each Side of the equation;  to isolate x on one side of the equation; & to solve for x ;
         x  + 4 − 4 = 18 − 4  ;
     to get:  x = 14 .
_______
 Now, find m∠F = 4x + 22  ;  
   Plug in 14 for x ; to solve:
                  m∠F = 4(14) +22 ;

                           =   56 + 22 ;

                  m∠F =  78°

        which corresponds to:
Answer choice:  [A]:  78°  .

Answer:

A

Step-by-step explanation:

Angles that are supplementary add to 180°.

[tex]4x+22+6x+18=180 \\ \\ 10x+40=180 \\ \\ 10x=140 \\ \\ x=14 \\ \\ \therefore m\angle F=78^{\circ}[/tex]

The figure that is shaded here has the quadrant and the sector as the two parts that it has.

The area of the shaded is given as (πr²) / 4 - bh/2

We have ACD as the sector of the circle.

such that we can see that the arc of AC is the quadrant of the circle nad it has the line at point o.

We would solve the area of the shaded as:

the area of a circle / 4 - the area of the triangle

this is mathematically written as

πr²/4 - 1/2bh

where

b = base

h = height

r = radius

This is the area of the shaded

An isosceles traingle would be formed when < A = < C = x

AO is equal to radius of the circle equal to the height CO

mathematically,

< A = < C = x

180 - 90 = 90 / 2

x = 45 degrees

We have to find the area of the sector

This is

= ∅/360 * πr²  

= (45 / 360) * (πr²)

= (πr²) / 4

From the calculation we have here, we would see that

the area of the shaded is  area of sector - area of the right angle triangle

= (πr²) / 4 - bh/2

When we go on to compare the sides we would then find out that they are equal. Therefore the shaded quadrant equals to the shaded sector.

The percent of decrease in the price of the scooter is 30.6%.

Step-by-step explanation:

In order to calculate the percent of decrease, you have to divide the difference between the two numbers by the original number and multiply the result for 100:

% decrease=((10.75-15.50)/15.50)*100

% decrease=-0.306*100

% decrease= -30.6%

The first step is to determine the number of people that one spring roll would serve.

Number of people that one spring roll would serve = 3 / 6 = 1/2

Number of people that s spring rolls would serve = number of people that 1 spring roll would serve x s

Number of people that 30 spring rolls would serve = 1/2 x 30 = 15

Number of people that 40 spring rolls would serve = 1/2 x 40 = 20

A stem-and-leaf plot is a table that is used to display numerical data.  A  stem-and-leaf plot has two column, one for the stem and the other for the leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 59, 5 would be the stem and 9 would be the leaf.

Mode is the number that occurs most frequently in a dataset. The mode is 59 because it appears 6 times in the dataset.

Range is the difference between the highest number and the lowest number

Range = 59 - 9 = 50

Median is the number at the center of the dataset.

Median = (n + 1) / 2

As per the direct variation formula, it take  11 hours : 6 minutes : 36 seconds to earn $25,000 for the restaurant.

Direct variation:

Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other.

Direct variation equation: y = kx

Given,

A local fast food restaurant takes in $9000 in a 4 hours period. Write a direct variation equation for the relationship income and number of hours.

Here we need to estimate how many hours it would take the restaurant to earn $25,000.

a) Let us consider income (I) directly varies to number of hours (h) where k is the constant of variation.

I = kh   ⇒  Direct variation equation

Solve for k:

9,000 = (k)(4)

k = 9,000/4

k = 2,250

b) When income (I) = 25,000, find the number of hours:

I = kh

25,000 = (2,250) (h)

h = 25,000/2,250

h = 11.11

It will take approximately 11 hours : 6 minutes : 36 seconds for the restaurant to earn $25,000.

The side x of the rectangle is 36.0 cm

A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.

All four angles of a rectangle are right angles.

The diagonal of a rectangle are equal in length to each other and they bisect each other at there point of intersection.

Therefore,

∠ COD = 48°

∠OCD = ∠ODC = 132 / 2 = 66°

Using sin law

OD / sin 66  = 16 / sin 48

OD sin 48 = 16 sin 66

OD =  16 sin 66 / sin 48

OD = 14.6167273223 / 0.74314482547

OD = 19.6687105931

OD = 19.7 cm

∠AOD = 180 - 48

∠AOD = 132°

∠OAD = ∠ODA = 48 / 2 = 24°

Hence, using sine law let's find x

19.7 / sin 24 = x / sin 132

x sin 24 = 19.7 sin 132

x = 19.7 sin 132 / sin 24

x = 14.6399530619 / 0.40673664307

y = -x(x - 1).

Step-by-step explanation:

y = a(x - b)(x - c) where a is a constant and b and c are the x-intercepts.

y = a(x - 0)( x - 1)

y =   ax(x - 1).

When x = 2, y = -2 so:

-2 = a(2) (2 - 1)

2a = -2

a = -1.

The number of smaller squares that can fit inside a larger square with a side length of 31 units is A. 961 smaller squares if the larger square is a plane.

A side length is one part of the length of an object.

Determining the number of smaller squares in a larger square depends on if the square is an enclosure or a plane.

If the square object is an enclosure, then it has three dimensions, length, width, and height, which are squared.  In that case, the number of smaller squares will be 29,791.

But if the square object is a plane with two dimensions, the number of smaller squares is 961.

Side length = 31 units

Area of a square plane = 961 unit² (31 x 31)

Volume of a square enclosure = 29,791 unit³ (31 x 31 x 31)

Thus, the number of smaller squares depends on the dimensions of the larger square.

The formula for y in terms of x is y = 8/x^3 and x is 1/2 when y = 64

The variation statement is given as

y is inversely proportional to the cube of x

This means that

y = k/x^3

Where k represents the constant of variation

Using the points on the table, we have

(x, y) = (1, 8)

This gives

8 = k/1^3

Evaluate

k = 8

So, we have

y = 8/x^3

Here, we have

y = 64 and y = 8/x^3

This gives

8/x^3 = 64

So, we have

x^3 = 1/8

Take the cube roots

x = 1/2

Hence, the value of x is 1/2

The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left hand side = right hand side) is a fundamental mathematical formula. For an unknown quantity represented by an unknown variable, equations can be solved to determine its value. It is clear that a statement is not an equation if there is no "equal to" sign in it. The phrase will be regarded as an expression.
