Answer 1

Answer:

z=32

Step-by-step explanation:

sum of these angles is equal to 180 so we add all of these angles and set it equal to 180

Z+12+2z+z+40=180

4z+52=180

    -52.  -52

      4z=128

       /4.  /4

       z=32

Hopes this helps

Answer 2

Answer:

z = 32° (degrees)

Step-by-step explanation:

Angles in triangle = 180° (degrees)

z + 12 + z + 40 + 2z = 180

2z + 2z + 12 + 40 = 180

4z + 52 = 180

4z = 180 - 52

4z = 128

z = 128/4 → 32

How many sides do 4 nonagons and 4 triangles have in all?

Answers

Answer: Regular nonagon has 9 sides. 9×9×9×9 is 6,561 which is the total of 4 nonagons. A regular triangle has 3 sides. 3×3×3×3 is 81 which is the total of 4 triangles. When you add 6,561 and 81 together, it's 6,642. Therefore, 6,642 is the 4 nonagons and 4 triangles in total.

to get the equation of any straight line, we simply need two points off of it, let's notice the picture above, the line passes through the origin and (8 , -5), so let's use those two points then

[tex]\stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{8}-\underset{x_1}{0}}} \implies \cfrac{ -5 }{ 8 } \implies - \cfrac{5 }{ 8 }[/tex]

Graph the inequality:
Elaina guessed on a maximum of 3 questions, q, on the science test. (That is a Q)

Answers

Answer: Q≤3

Step-by-step explanation:

Elaina guessed on a max of 3 questions. So he/she could have guessed on 3 or less (3 included.) Since 3 is included the dot at 3 would be filled in (aka closed circle.) And the inequality would be pointing left.

Answer:

The answer is the image.

Step-by-step explanation:

Determine the equation represented by the word problem, which is [tex]q\leq 3[/tex].Graph the equation accordingly. Because the range includes 3, you put a closed circle on 3. And since it also includes anything less than 3, you arrow should go from right to left.

This assignment is due soon! If someone can help it would be great. It is about triangle angle sun theorem.

Answers

X = 44 because you set it up like an equation

Ok so basically we know that all the angles in a triangle add up to 180 degrees.

That means

(x-7) + (2x) + (x+11) = 180 because we combined all the angle measures.

To solve this equation we've got to combine like terms.

We can combine the x's together so we have 4x + (-7) + 11 =180.

Then we can combine -7 and 11 to get 4 because 11-7=4.

Now our equation is 4x+4=180.

We can subtract 4 from both sides of the equation to get 4x=176.

Then simplify this by doing 176/4=44.

That means x=44.

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night, the theater makes $1,512 from popcorn sales and $1,584 from nacho sales. If on the next night the employees sell $1,848 of popcorn, how much is earned from nachos?

Answers

Answer:

Using proportions, it is found that $1,225 is earned from nachos.

This question is solved by proportions, using a rule of three.

The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.

When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?

The rule of three is:

$1,540 - $1,330

$1,672 - $x

Applying line multiplication:

$1,225 is earned from nachos.

Filomena applies the commutative property to the product.
( 7/15 ) x ( −11 ) x ( 30 )
Which expression illustrates the commutative property applied to the product?
*someone please answer this before 2:20 :)*

Answers

Answer: Option 4

Step-by-step explanation:

Commutative property is when you change the order of the operands but it does not change the answer like 5 times 6 and 6 times 5 all = 30.

In this case, the fourth answer is correct because 7/15 x -11 x 30 is the same as 7/15 x 30 x -11 but -11 and 30 are switched around.

Hope this helps you!

I can agree but the easiest way to do that you do 5times 6makes 30 but you can do the other way round and you still going to have the same answer innit

Answer: Not really

Step-by-step explanation:

Decimals just look better than fractions. People don't normally say, "I have two and 4/25 dollars!" They just don't want to have to work in order to determine how much something costs or how far someone walked. If the question states clearly to write it as a fraction then do so, but otherwise, do it however you want to.

An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers.

Which equation could be used to find n, the total number of markers in stock?
A:80 × 48 + 34 × 20= n
B:80 + 48 × 34 + 20 = n
C:80×48−34×20=n
D:80 + 48 + 34 + 20 = n

Answers

The answer would be A
Because if you have 80 large boxes and a large box has 48 makers that would be 80x48 and the same thing for the small boxes which would be 34x20 the you would add both of this to get the total number of makers so it would be 80x48 + 34+20= n

Your team wins 16 medals at a competition. The medals are gold, silver, and bronze in a ratio of 6 : 1 : 1. How many of each medal did your team win?

Answers

Answer: 12 gold, 2 silver and 2 bronze

Step-by-step explanation:

16 is the total number of medals and in the ration 6:1:1 there are 8. To get to 16 total medals you need to double each of them. 6x2, 1x2 and 1x2. Now you have a ratio of 8:2:2. 8+2+2=16.

The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Your group wins 16 decorations at a rivalry. The decorations are gold (G), silver (S), and bronze (B) in a proportion of 6: 1: 1.

G/6 = S/1 = B/1 = x

G = 6x

S = x

B = x

Then the equation is written as,

6x + x + x = 16

8x = 16

x = 16 / 8

x = 2

Then the number of each medal is given as,

G = 6x = 6(2) = 12

S = x = 2

B = x = 2

The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.
