The Problem We Are Working Is:If John Can Paint Half Of A Room In Two-thirds Of An Hour, What Part Of

Answers

Answer 1

Answer:

Answer: 0.75(3/4) part of the room

Step-by-step explanation:

Answer 2

Answer:

0.75(3/4) part of the room

Step-by-step explanation:

if he takes 2/3 hours to paint 0.5 room

then he will take 1 hour to paint x

cross multiply we have

x= 0.5/2/3

x=0.5*3/2

x= 1.5/2

x=0.75 part of the room

75/100= 15/20=3/4 part

for A you should take each plotted point and change the sign of the x values. for example (-1,3) should become (1,3) and (-4,4) should become (4,4)

for B take each point and flip the variables and x's sign. (-1,3) should become (3,1)

for C take every x value and subtract 2. (-1,3) should become (-3,3)

for D take each point and flip the variables and y's sign. (-1,3) should become (-3,-1)

Step-by-step explanation:

the way i learned how to find slope from a table was to calaucate 2 points.usually the first 2 pairs. so in your table you would take the points(1,8)&(3,5) then you subtract your x&ys.

1-3&8-5 then your x goes on bottem and y on top.

1-3=-2

Step-by-step explanation:

one platter has 6 veggie wraps, 12 turkey wraps and costs 64.50 another platter has 8 veggie wraps 8 turkey wraps and costs $56


Which system of equations represents the situation if x represents the cost of a veggie wrap and y represents the cost of a turkey wrap?
A.12x + 6y = 568x + 8y = 64.50
B.6x + 12y = 64.508x + 8y = 56
C.x + 2y = 64.50x + y = 56
D.6x = 64.508y = 56

Answers

Answer: $3.25

Step-by-step explanation: The computation of the cost of a veggie wrap is shown below:

Let us assume the veggie strap be x

And the turkey wrap be y

Now the equations are

6x + 12y = $64.50

x + 2y = $10.75

8x + 8y = $56

x + y = 7

Now

x + 2y = $10.75

x + y = $7

y = $3.75

So x = $7 - 3.75

= $3.25

So, the correct option is option (B).

Linear simultaneous equation:

Simultaneous linear equations are the system of two linear equations in two or three variables that are solved together to find a common solution. The simultaneous linear equation is represented as follows:

[tex]a_1x+b_1y=c_1\\a_2x+b_2y=c_2[/tex]

It is given that,

[tex]x[/tex] represents the cost of a veggie wrap and  [tex]y[/tex] represents the cost of a turkey wrap.

Now, using the first part of the given question we get,

[tex]6x+12y=64.50...(1)[/tex]

Again in the second part of the given question is 8 veggies wraps 8 turkey wraps and costs $56 then we get the equation as,

[tex]8x+8y=56...(2)[/tex]

Then from equations (1) and (2) we get the equation as,

[tex]6x+12y=64.50\\8x+8y=56[/tex]

The diameter of a pizza is 14 inches. The pizza has 8 slices of equal size. Which of the following is the closest to the area of a slice?

Answers

Answer:

Step-by-step explanation:

First let us find the area of the whole pizza. Area of a circle is:

[tex]A=\pi r^2[/tex]

Then, we have diameter as:

[tex]diameter\div2=radius[/tex]

So, then using these formulas we would have,

[tex]16\div2=8\\A=8\pi \text{ or }25.12[/tex]

Now, one slice is [tex]\frac{1}{8}[/tex] of the entire pizza. So, we would have:

[tex]8\pi\div8=1\pi\\\text{ or }\\25.12\div8=3.14[/tex]

HOPE THIS HELPS!!!!!!!!
A full circle is 360 degrees, so one slice is an eighth of that. 360 / 8 = 45 degrees.

Answers

Answer:

Radius is the distance from the center of the circle to the edge (if you were to cut just a slice of pizza)

diameter is directly in the middle from one end to the other (if you were to cut the pizza in half)

this means that the diameter is DOUBLE the radius

circumference is the length of the outside of the circle (so the length of the pizza crust)

this one is tricky because to find circumference you need to do  [tex]2\pi r[/tex] (r is the value of the radius)

so for problem 1 the radius is 3 cm (the line is equivalent to if you were trying to cut out one slice of pizza)

the diameter is DOUBLE the radius, so if you were to cut the pizza in half all the way it would be 6 cm

and the circumference ([tex]2\pi r[/tex]) is 2 * pi * 3 cm

because it says to round pi to 3.14, the circumference would be 18.84
