A sandwich store charges $20 to have 3 turkey subs delivered and $26 to have 4 delivered. Is the relationship between number of turkey subs delivered and the amount charged proportional?

Answer:

C then B

Step-by-step explanation:

If  2x > 50 , then x > 25.  Draw a circle at x=25 and then extend a ray in the positive x direction away from x = 25.

If x + 6 < 32, subtract 6 from both sides, obtaining x < 26.

    Draw a cirlce at x=26 and extend a ray from that x to the left.

Answer:

graph c is 2x> 50 and graph b is x+6<32

Step-by-step explanation:

For 2x>50 you first divide 50 by2 leaving you with x>25 therefore x is all numbers greater than 25.

For x+6<32 you first subtract 6 from 32 leaving you with x<26 therefore x is  all numbers less than 26.

Step-by-step explanation:

The number of degrees in the measure of angle A is

⇒ A = 60°

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ sin (A - 30) = cos 60°

Now,

We know that;

⇒ sin (90 - θ) = cos θ

Hence, We get;

⇒ cos 60° = sin (90 - 60)

Substitute above value in equation (i), we get;

⇒ sin (A - 30) = cos 60°

⇒ sin (A - 30) = sin (90 - 60)

⇒ (A - 30) = (90 - 60)

⇒ A - 30 = 30

⇒ A = 60°

Thus, The number of degrees in the measure of angle A is

⇒ A = 60°

Step-by-step explanation:

Area of outer triangle = [tex]\dfrac{4x*(4x+3)}{2}= 2x*(4x +3)[/tex]

                                    = 2x*4x + 2x*3

                                   = 8x² + 6x

Area of inner triangle= [tex]\dfrac{2x*(2x+5)}{2}=x*(2x+5)=x*2x+x*5=2x^{2} + 5x[/tex]

Area of aluminium = area of outer triangle - area of inner triangle

                        = 8x² + 6x + 2x² + 5x

                        = 10x² + 11x

Area of 20 aluminum borders = 20*(10x² + 11x)  = 200x² + 220x

b) x = 25 cm

Area of 20 aluminum borders = 200*25² + 220*25

                                                  = 200 * 625 + 220*25

                                                 = 125000  + 5500

                                                  = 130500 cm²

c) Area of inner triangle (Glass) = 5500 cm²

Cost of aluminium = 130500 * 0.06 = $ 7830

Cost of glass = 5500 * 0.03 = $ 165

Cost of making 20 windows =  7830 + 165 = $ 7995

Answer:

z = 36

Step-by-step explanation:

Isolate the variable, z. Note the equal sign, what you do to one side, you do to the other. Multiply 3 to both sides of the equation:

(z/3) * 3 = (12) * 3

z = 12 * 3

z = 36

z = 36 is your answer.

~

Answer:

z = 36

Step-by-step explanation:

In order to find z, solve with the opposite operation.

Since z and 3 are dividing to equal 12, multiply 12 and 3 to find z.

Multiply 12 and 3:

[tex]z=12(3)[/tex]

[tex]z=36[/tex]

To take the average of the weight of the cat in the month of April is the following:

9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48

But then divide that by the number of samples:

48/5=9.6

The mean for April is 9.6

To take the average of the weight of the cat in the month of November is the following:

9.4 + 9.3 + 9.1 + 9.2 + 9 = 46

But then divide that by the number of samples:

46/5=9.2

Then, lastly, subtract the mean from November by the mean of April:

Considering that the probability of Noah making each free throw is of 75%, the ways that Noah could accurately simulate the number of free throws he will make in his next 6 attempts are:

C. Put 3 red chips and 1 white chip in a bag. Draw a chip from the bag, record the result, and put it back in the bag. Do this 6 times and count the number of red chips drawn.

D. Make a spinner with 4 equally-sized sections. Color three sections green and one sections red. Spin the spinner 6 times and count the number of times the spinner lands on green.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, for each free throw, Noah has a 75% probability of making it. Hence, the equivalent ways are the ones in which the probability of a success on each trial is of 75%, considering 6 trials.

Hence, options C and D are correct.

Answer:

[tex]f^{-1}(x) = ( \frac{4y - 36}{-3} )[/tex]

Step-by-step explanation:

f(x)=-3/4x+9

let f(x) be y .......................to find inverse we have making x the subject.

y = -3/4x+9

y - 9 = -3/4 x

-3x = 4y - 36

x = (4y - 36)/-3

so, [tex]f^{-1}(x) = ( \frac{4y - 36}{-3} )[/tex]

[tex]\\ \tt\hookrightarrow y=\dfrac{-3}{4}x+9[/tex]

[tex]\\ \tt\hookrightarrow y-9=\dfrac{-3x}{4}[/tex]

[tex]\\ \tt\hookrightarrow -3x=4y-36[/tex]

[tex]\\ \tt\hookrightarrow x=\dfrac{-4}{3}y+12[/tex]

Step-by-step explanation:

Answer:

The correct answer is 5.

Step-by-step explanation:

For the first circle,

When we add 6,18,12,

we get 6+18+12 = 36

Now

when we divide 36 with 6 we get 6.

again,

for second circle,

When we add 10,53,18

we get 10 + 53 + 18 = 81

when we divide 81 with 9 we get 9.

Now

let the unknown number be x.

so,

Pattern : When we add all of the number in the circle excluding the smallest number and dividing it by the smallest number we get the same number.

following the pattern,

Here in the options x>=5 (smallest number in the circle 3)

so, we can take smallest number as 5.

As the pattern,

(x+10+10)/5 = x

or, (x+20)/5 = x

or, x+20 = 5x

or, 5x-x = 20

or, 4x = 20

so, x = 5
