It's true If every pair of consecutive angles of a quadrilateral are supplementary, then the quadrilateral must be a parallelogram.

Rectangles, rhombus, and squares are parallelograms. A trapezoid has as a minimum one pair of parallel facets. The parallel aspects are referred to as the bases and the non-parallel sides are called the legs. There are three kinds of trapezoid - isosceles, right-angled, and scalene trapezoids.

To identify a parallelogram, the shape has to fulfill one of the following standards:

Answer: [tex]12x-15[/tex]

Step-by-step explanation:

Given: Sunny earns $12 per hour delivering cupcakes. She worked for x hours this week.

The total earning for this week = [tex]12x[/tex]

Also, she was charged $15 for a late delivery on Tuesday.

It means, The total earning for this week =[tex]12x-15[/tex]

So if Sunny earns $12 per hour delivering cupcakes. She worked for x hours this week and was charged $15 for a late delivery on Tuesday then her earning for this week = 12x-15

The value of x will be equal to 21.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be solved as below:-

√(x-5) + 7 = 11

√(x-5)  = 11 -7

√(x-5)  = 4

x - 5 = 4^2

x - 5 = 16

x = 16 + 5

x = 21

Therefore, the value of x will be equal to 21.

Answer:

This is correct! answer is (2 1/2, 10) and (3/12)

Step-by-step explanation:

Answer:

m ≥ 82 + 32w

m ≥ 402

Step-by-step explanation:

Here, w represents the number of weeks and m represents the total amount in the account after w weeks,

The amount of money saved in each week = $ 32,

So, the total amount saved after weeks = 32w dollars,

Since, the original amount in the account = $ 82

The total amount in the account = 82 + 32w

Thus, the required inequality would be,

m ≥ 82 + 32w

If w = 10,

The amount in the account after 10 weeks = 82 + 32(10) = 82 + 320 = $ 402

⇒ m ≥ 402  

That is, the closed circle on 402 and shaded right in the number line ( shown below )

Answer:

Step-by-step explanation:

we are given the equation a+b-c=180

Now to solve it for c we need to isolate the c

first step can be addition of c to  both side

a+b-c+c=180+c

a+b=180+c

now in second step we subtract 180 from both sides to get

a+b-180=180+c-180

a+b-180 = c

c= a+b-180

Answer:

B. Score(3)

Step-by-step explanation:

Given,

Bella's score on a spelling test is a function of the number of hours she studies.

Let x represents the number of hours and S represents her score after x hours,

Thus, her scoring after x hours = S( x )

If she studies for 3 hours,

That is, x = 3,

Then her score would be S(3) or we can say that score(3).

Hence, option 'B' is correct.

Answer:

[tex]y=x^2+16x+64[/tex]

Step-by-step explanation:

A quadratic needs 2 solutions, but since you only have 1, I am to assume that x = -8 twice (or multiplicity of 2).  If x = -8, then in factor form, it's (x + 8).  Muliplying that by itself twice:

(x + 8)(x + 8):

[tex]x^2+8x+8x+64=0[/tex]

Simplifying gives you:

[tex]x^2+16x+64=y[/tex]

Final answer:

Harvey has 112 marbles distributed equally across seven trays. Each tray holds 16 marbles, therefore, on three trays, Harvey will display a total of 48 marbles.

Explanation:

Harvey has 112 marbles in his collection and uses seven trays to hold all of the marbles. To find out how many marbles Harvey will display on three trays, we need to divide the total number of marbles by the total number of trays to find out how many marbles each tray holds.

First, divide 112 marbles by 7 trays to find out how many marbles go on each tray. The calculation is as follows:

112 marbles ÷ 7 trays = 16 marbles per tray

Now that we know each tray holds 16 marbles, to find out how many marbles are displayed on three trays, we multiple the number of marbles per tray by the number of trays:

16 marbles per tray × 3 trays = 48 marbles

Therefore, Harvey will display 48 marbles on three trays.
