Natalie paid $20.7 for 3 small pizzas and a salad which was $3.

a- Write an equation to represent the situation

b- solve the equation to find the cost of one pizza. Show your work

Answers

Answer:

Step-by-step explanation:

a) Let the cost of a Pizza = $ x

Cost of three pizza's = 3 *x = 3x

cost of 3 pizza + cost of a salad = $ 20.7

3x + 3 = 20.7

b) 3x + 3 = 20. 7     {Subtract 3 from both sides}

3x       = 20.7 - 3

     3x = 17.7  {Divide both sides by 3}

       x = 17.7/3

      x  = 5.9

Cost of one pizza = $ 5.9

Part A
$20.70=3p+3
Part B
$20.70=3p+3
$17.90=3p
$5.90=p
So the cost of one pizza is $5.90

Answer:while baking a cake it is best to use a round pan if you are going to have the a 7-inch diameter

Step-by-step explanation:

The rectangular cake pan has a larger volume. If you multiply the length times the height times the width it gives you the total volume of 108 inches. The round cake pan only gives you a total volume of 76.97 inches, which is less than the rectangular pan.

I really don't know how to do this-

Answers

The sum of the interior angles of any quadrilateral is 360°.

So,

90° + 90° + 52° + x = 360°

=> 232° + x = 360°

=> x = 360° - 232°

=> x = 128°

Answer:

x = 128

Step-by-step explanation:

All angles on a trapezoid must add up to 360 degrees. So we have 3 of our 4 angles so we can solve this as an equation

90 + 90 + 52 + x = 360

232 + x = 360

x = 128

The function f(x) = –(x – 20)(x – 100) represents a company’s monthly profit as a function of x, the number of purchase orders received. Which number of purchase orders will generate the greatest profit? *

Answers

Answer:

Explanation is the answer

Step-by-step explanation:

The max happens at the vertex. The line of symmetry runs through the vertex. So if you have the x-intercepts of the graph, the axis of symmetry will be the same distance from them but on opposite sides of the axis of symmetry. So if you have the x-intercepts then you can average them to fnd the x-coordinate of the middle point, the vertex.

So your factored form says the x-intercepts are (20,0) and (100,0).

So the x-coordinate of the vertex is (20+100)/2=120/2=60.

The question is asking for x-coordinate of the vertex so we are done.

Question :-

A cylinder has a radius of 4.9 ft and a height of 7.8 ft. What is the surface area of the cylinder?

Answer :-

The surface area of the cylinder is 390.8044 ft².

[tex] \rule{180pt}{3pt}[/tex]

Diagram :-

[tex]\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{4.9 \: ft}}\put(9,17.5){\sf{7.8 \: ft}}\end{picture}[/tex]

Solution :-

As per the provided information in the given question, we have been given that the radius of the cylinder is 4.9 ft. The height of the cylinder is 7.8 ft. We have been asked to find or calculate the surface area of the cylinder.

To calculate the surface area of the cylinder, we will use the formula below :-

[tex]\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh \:\:}}[/tex]

Substitute the given values into the above formula and solve for surface area:

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh[/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(4.9 \: ft)^2 + (2)(3.14)(4.9\: ft)(7.8\:ft) [/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(24.01\: ft^2) + (2)(3.14)(38.22\:ft^2) [/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(75.3914 \: ft^2) + (2)(120.0108 \: ft^2) [/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 150.7828 \: ft^2 + 240.0216 \: ft^2 [/tex]

[tex]\sf:\implies \bf{Surface \: Area_{(Cylinder)} = 390.8044 \: ft^2}[/tex]

Therefore :-

The surface area of the cylinder is 390.8044 ft².
