A restaurant sells cheeseburgers to chicken sandwiches in a ratio of 7:2. If the restaurant sells 12 chicken sandwiches one day, how many cheeseburgers does it sell

Answers

Answer:

Food problems are fun  :D

Step-by-step explanation:

[tex]\frac{7}{2}[/tex] = [tex]\frac{cheeseburgers}{chicken}[/tex]

chicken =12  sooo..

[tex]\frac{7}{2}[/tex] = [tex]\frac{x}{12}[/tex]

and solve for x.... that is... get x by itself... "isolate x"

12 * [tex]\frac{7}{2}[/tex] = x

6 * 7 = x

42 = x

the restaurant sold 42 cheeseburgers  :P  

Estimate the cost of painting the inner
wall of a well, if the depth of the well is
14 ft and the diameter is 8 ft. The cost of
painting 2.5 sq. ft is 20.​

Answers

Answer:

2816 rupees

Step-by-step explanation:

here , depth = 14 ft

diameter = 8 feet

so , radius = 4 ft

We will paint it in its C.S.A.

C.S.A. of a cylindrical well

= 2πrh

= 2×(22/7)× 4 × 14

= 352 ft²

so,

cost = rate per unit area × area

= (20/2.5)×352

= 8×352

= 2816

so,the cost of the painting will be 2816 rupees

What are the coordinates of the point on the directed line segment from (-8, 5)(−8,5) to (4, -3)(4,−3) that partitions the segment into a ratio of 5 to 3?

Answers

Answer:

(2, -7/2)

Step-by-step explanation:

According to the midpoint theorem;

M(X, Y) = [(ax1+bx2/a+b), ay1+by2/a+b ]

(x1, y1) and (x2, y2) are the coordinates

a:b is the given ratio

Given the following

Coordinate of the line segment (-8, 5) and (4, -3)

Ratio: 5:3

Get the X coordinate;

X = ax1 + bx2 / a+b

X = 5(-8) + 3(4)/5+3

X = -40+12/8

X = -28/8

X = -7/2

Get the Y coordinate

Y = ay1 + by2 / a+b

Y = 5(5) + 3(-3)/5+3

Y = 25-9/8

Y = 16/8

Y = 2

Hence the required coordinate is (2, -7/2)

3 feet after 5 seconds. What is the rate of change between the 3rd second
and the 5th second? Hint: your ordered pairs should be (times in seconds,
height in feet). Your answer should be in feet/s. *

Answers

Answer:

2.6 ft/s

Step-by-step explanation:

Given that a soccer ball kicked into the air reaches 15 feet in 3 second. The first rate or speed will be:

Rate 1 = 15/3 = 5 feet/s

and falls to 3 feet after 5 seconds. Also, the second rate or second speed will be:

Rate 2 = ( 15 - 3 ) / 5

Rate 2 = 12 / 5

Rate 2 = 2.4 ft/ s

What is the rate of change between the 3rd second and the 5th second? That is, the change in speed. Which can be expressed as:

The rate of change = 5 - 2.4

The rate of change = 2.6 ft/s

Step-by-step explanation:

Describe how the graph of y= x^2 can be transformed to the graph of the given equation.
y = x^2 - 12 (5 points)

a) Shift the graph of y = x2 left 12 units.
b) Shift the graph of y = x2 down 12 units.
c) Shift the graph of y = x2 right 12 units.
d) Shift the graph of y = x2 up 12 units.

Answers

Answer:

b

Step-by-step explanation:

Given y = x² then y = x² + c is a vertical translation of y = x²

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 12 < 0

Thus y = x² - 12 is the graph of y = x² shifted 12 units down → b

Answer:

b) Shift the graph of y = x2 down 12 units.

Step-by-step explanation:

Graphs

The graph of the function

[tex]y=x^2[/tex]

can be found by giving the variable x some values and calculating the values of y as follows:

For x=-2, [tex]y=(-2)^2=4[/tex]. Point (-2,4)

For x=-1, [tex]y=(-1)^2=1[/tex]. Point (-1,1)

For x=0, [tex]y=(0)^2=0[/tex]. Point (0,0)

For x=1, [tex]y=(1)^2=1[/tex]. Point (1,1)

For x=2, [tex]y=(2)^2=4[/tex]. Point (2,4)

The graph of

[tex]y=x^2-12[/tex]

Can be similarly found:

For x=-2, [tex]y=(-2)^2-12=-8[/tex]. Point (-2,-8)

For x=-1, [tex]y=(-1)^2-12=-11[/tex]. Point (-1,-11)

For x=0, [tex]y=(0)^2-12=-12[/tex]. Point (0,-12)

For x=1, [tex]y=(1)^2-12=-11[/tex]. Point (1,-11)

For x=2, [tex]y=(2)^2-12=-8[/tex]. Point (2,-8)

The graphs are shown in the attached image. It can be clearly seen that the second graph (in blue) is shifted down 12 units with respect to the red graph. Answer:

b) Shift the graph of y = x2 down 12 units.

In this question data is missing and I filled it out and calculated the questions accordingly. Please refer to the attachment for the data calculated.

Step-by-step explanation:

First of all, this question is incomplete. It lacks the data needed to calculate the required things.

So, I  figured out the question and I will try my best to solve the question at hand.

I have calculated the some data sheet in excel. Please refer to the attachment for that data.

let a be the salaries

b be the viewers

[tex]S_{aa}[/tex] = ∑[tex]a^{2}[/tex]  - [tex]\frac{ Summtion a^{2} }{n}[/tex]

[tex]S_{aa}[/tex] = 7522.8571

[tex]S_{bb}[/tex] = ∑[tex]b^{2}[/tex]  - [tex]\frac{ Summtion b^{2} }{n}[/tex]

[tex]S_{bb}[/tex] = 47.1943

[tex]S_{ab}[/tex] = ∑[tex]ab^{}[/tex]  - [tex]\frac{ Summtion a x Summation b^{} }{n}[/tex]

[tex]S_{ab}[/tex] = -76.8286

Now the slope of the required regression equation is:

Slope =  [tex]S_{ab}[/tex]/[tex]S_{aa}[/tex] = -76.8286/7522.8571 = -0.010

And the intercept of the required regression equation:

intercept = [tex]\frac{1}{n}[/tex] x (∑b - slope x ∑a) = 5.064

So, the regression equation will be:

y = intercept + slope x

y = 5.064 - 0.010x

Here, in this question x = 33

y = 5.064 - 0.010 (33)

y = 4.734 million views

Screen-printing a batch of shirts requires 1 minute per shirt in addition to 4 minutes of initial set-up time. If it takes 41 minutes to screen-print a bath of shirts, how many shirts are in the batch?

Answer with the amount of shirts.

Answers

Answer:

There are 37 shirts in the batch.

Step-by-step explanation:

Since it takes an initial 4 minutes to set up the screen-printer, we can subtract 4 from 41 minutes to get the time used to print the shirts.

41 - 4 = 37

Since each shirt requires 1 minute of screen printing and there are 37 minutes, we can divide 37 by 1.

37 / 1 = 37

So there are 37 shirts in this batch. Hope this helps.

Answer:

P+Q+R+S+T=540. then substitute x for result in p

Step-by-step explanation:

i would work it out but im lazy sorry

In a pentagon, there are 540 degrees

First, find x.

Set up the equation

132 + (4x+2) + 128 + (5x -11) + (4x - 10) = 540

Combine like terms

260 +13x -19 = 540

241 + 13x = 540

solve

13x = 299

x = 23

Now plug x in to angle p (4x + 2)

4(23) + 2

92 + 2 = 94

Therefore angle P = 94 degrees

Answer:

  x ∈ {1/2, 1, 3, i, -i}

Step-by-step explanation:

We assume your function is supposed to be ...

  f(x) = 2x^5 -9x^4 +12x^3 -12x^2 +10x -3=0

I find it convenient to use a graphing calculator to find the real roots of higher-degree polynomials. The attached shows the real roots are ...

  x = 1/2, 1, 3

Factoring those out leaves the quadratic factor ...

  x^2 +1 = 0

That one has roots ±i.

So, the full complement of roots is ...

  x ∈ {1/2, 1, 3, i, -i}

_____

Descartes' rule of signs tells you the real roots are all positive. The rational root theorem tells you that rational roots are in the set {1/2, 1, 3/2, 3}. The sum of coefficients is 0, telling you that x=1 is a real root.

Factoring that from the polynomial leaves the 4th-degree factor ...

  2x^4 −7x^3 +5x^2 −7x +3 . . . . . division shown in 2nd attachment

For x=1, this has a negative value (-4), so you know there is a root between f(0) =3 and f(1) = -4. The only rational choice is 1/2.

Similarly, factoring that from the polynomial (along with a factor of 2) leaves the cubic ...

  x^3 -3x^2 +x -3 . . . . . division shown in 3rd attachment

This is clearly factorable by grouping to (x -3)(x^2 +1), so we have our third real root and the quadratic that yields the complex roots.

Answers

[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

Step-by-step explanation:

Given the expression

[tex]a+\frac{2b}{3}=\frac{2}{c^9}[/tex]

subtract a from both sides

[tex]a+\frac{2b}{3}-a=\frac{2}{c^9}-a[/tex]

Simplify

[tex]\frac{2b}{3}=\frac{2}{c^9}-a[/tex]

Multiply both sides by 3

[tex]\frac{3\cdot \:2b}{3}=3\cdot \frac{2}{c^9}-3a[/tex]

Simplify

[tex]2b=\frac{6}{c^9}-3a[/tex]

Divide both sides by 2

[tex]\frac{2b}{2}=\frac{\frac{6}{c^9}}{2}-\frac{3a}{2}[/tex]

Simplify

[tex]b=\frac{6-3ac^9}{2c^9}[/tex]

Calculating 4/b

[tex]\frac{4}{b}=\frac{4}{\frac{6-3ac^9}{2c^9}}[/tex]       ∵ [tex]b=\frac{6-3ac^9}{2c^9}[/tex]

[tex]\frac{4}{b}\:=\frac{4\:\times \:\:2c^9}{6-3ac^9}[/tex]

[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

Therefore, we conclude that:
