True or False: the relationship shown in the mapping diagram is a function

Answer:

[tex] \huge{ \boxed{ \bold{ \sf{ \pink{80°}}}}} [/tex]

Step-by-step explanation:

✰ [tex] \underline{ \sf{First, \: Let's \: learn \: about \: internal \: angles \: of \: a \: triangle}}[/tex]

The angles which are formed inside by the joining of arms of a triangle is called interior angles of a triangle. According to the figure provided , In ∆ ABC , ∠ABC , ∠ ACB , ∠ BAC are interior angles because they lie inside the ∆ ABC and sum of such interior angles is always 180°.

☄ [tex] \underline{ \underline{ \sf{Provided : }}}[/tex]

☄ [tex] \underline{ \sf{To \: Find :}}[/tex]

✏ [tex] \text{Set \: up \: an \: equation \: and \: solve \: for \: x.}[/tex]

[tex] \text{{∠a \: + \: ∠ \: b \: + \: ∠ \: c \: = \: 180 \degree}}[/tex]

→ [tex] \sf{2x + 3x + 4x = 180 \degree}[/tex]

→ [tex] \sf{9x = 180 \degree}[/tex]

→ [tex] \sf{ \frac{9x}{9} = \frac{180 \degree }{9} }[/tex]

→ [tex] \sf{x = 20 \degree}[/tex]

The value of x is 20°. As we are asked to find the measure of ∠C , substituting the value of x in 4x :

[tex] \text{∠c = 4x}[/tex]

→ [tex] \sf{∠ \: c \: = 4 \times 20 \degree}[/tex]

→ [tex] \boxed{ \bold{ \pink{ \sf{∠c \: = 80 \degree}}}}[/tex]

Hence , The measure of ∠ C is 80 °

Answer:

80

Step-by-step explanation:Solution:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The given numbers are 78 & 80

step 2 Find the sum of the given two numbers.

sum = 78 + 80 = 158

step 3 Divide the sum by 2 to get the average.

average = 158/2

= 79

Thus, 79 is an average of positive integers 78 and 80.

Answer:

Rhombus

Step-by-step explanation:

It does not have congruent diagonals

Answer:

7

Step-by-step explanation:

the median is the middle and if you order them

4,5,6,8,8,9 then you remove one from each side until you have 6,8 so you go in-between the two (seven)

Answer:

7

Step-by-step explanation:

You need to arrange the numbers in an increasing order:

4 5 6 8 8 9

then you need to count how many values we have in the specific set:

6 total values

now we need to find the middle of our set

4 5 6 II 8 8 9

and then we divide the two numbers next to the middle part (6;8) and divide them by 2

(6+8):2=7

Answer:

(1-1)+(5×2)

Answer: 24

Step-by-step explanation: thanks

Answer:

elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.

  In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.

  That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

Step-by-step explanation:

A transform is a dilation that has changed the size and shape of such a geometric form.  

Segment of let line is:

[tex]\to x_i=x_n+t(x_{n+1} -x_n)\\\\\to y_i=y_n+t(y_{n+1} -y_n)[/tex]

[tex]scale \ factor = \frac{1}{2}[/tex]

The dialling is based on its origin and also the line section, in order to provide new coordinates [tex](\frac{x_n}{2}, \frac{y_n}{2}) , (\frac{x_{n+1}}{2}, \frac{y_{n+1}}{2})[/tex] So, the line segment is unchanged, and also has shorter.

Answer:

128x + 288

Step-by-step explanation:

Given the expression 2^5(4×+9)

on factoring

2^5(4×+9) = 2^5(4x) + 2^5(9)

2^5(4×+9) = 32(4x) + 32(9)

2^5(4×+9) = 128x + 288

Hence the expression is also equivalent to 128x + 288

Answer:

Blank 1: 28

Blank 2: 42

Blank 3: 22

Answer: It will take 7 sessions.

Step-by-step explanation:

We already know the 3 blanks from the equation 28x = 42 + 22x

Now to find the answer.

28x = 42 + 22x

Subtract 22x from both sides. This cancels the +22x.

28x - 22x = 42

Subtract 22x from 28x to get 6x

6x = 42

Divide both sides by 6. This undoes the multiplication by 6.

x = 42/6

Divide 42 by 6 to get 7.

x = 7

It will take 7 sessions for the costs to match.

Answer:

G(x) = 18

Step-by-step explanation:

first you add x on both sides (-7+x=11)

then you add 7 on both sides and end up with (x=18)
