Answer:

D. Yes, because it passes the vertical line test

Step-by-step explanation:

the vertical line test is a test you do by drawing a vertical line through the graph of the function if more than one point from the function lies on the line it does not represent a function

in this graph at any part if you draw a vertical line it passes through one point only

Answer:

Okay so what you need to know here is for a graph to be considered a function it has to pass the vertical line test. This means that if a vertical line is moved across the graph and touches the graph at only one point, then it is considered a function. But if the vertical line touches the graph at more than one point, then it is not considered a function.

Step-by-step explanation:

But for this graph, I know it wouldn't be A, B, or C...... This is because this  and it touches the graph at only one point. We know the graph has to pass the vertical line test to be a function. But we can see here that it does because on the graph it only touches one point as you can see in that attachment. So, It would be D.... I'm pretty sure it is D though. Sorry if it's wrong. I tried to do what I could bcs I'm not really good at math lol

Please mark as brainliest pls and I have attached of graphs that pass the vertical line test to help you understand it better!

Answer:

Perimeter= 20 inches

Step-by-step explanation:

since the perimeter of a plane figure is distance round the shape, we add all the sides in order to get 20inches.

Perimeter= 4+5+4+4+3= 20incjes. That's for the perimeter.

Then area, we divide the shape into two portions sides A and B.

We find the area of side A which is a rectangle so, the are = Length×Breadth..

= 4×5 = 29cm².Side B is a triangle so it's area will be

Answer:

Total Perimeter = 30 in

Total Area: 30 in²

Step-by-step explanation:

First, do the perimeter of the triangle.

Equation: side+side+base = 3 + 4 + 5 = 12

Next is the perimeter of the rectangle.

Equation: 2(length + width) = 2·(5 + 4) = 18

Then, add the two perimeters:

12 + 18 = 30 in (Total Perimeter = 30 in)

Next, do the area of the triangle.

Equation: height • base/2 = 4 · 5/2 = 10

Finally, the area of the rectangle.

Equation: width • length = 4 · 5 = 20

Then, add the two areas:

10 + 20 = 30 (Total Area: 30 in²)

An interior angle of a polygon is found by subtracting 2 from the number of sides, multiplying that by 180 And then divide by the number of sides:

40-2 = 38

38 x 180 = 6840

6840/40 = 171

Answer : 171 degrees

Answer:

[tex]5c^2+2cd-2d^2-15[/tex]

Step-by-step explanation:

Perimeter of a 2D shape = distance around the outside.

Therefore, to calculate the perimeter, sum the lengths of all the sides.

[tex]\textsf{perimeter} \ =(4c^2+4cd+12)+(c^2-d^2+1)+(3cd+4d^2-30)+(-5d^2-5cd+2)[/tex]

[tex]=4c^2+4cd+12+c^2-d^2+1+3cd+4d^2-30-5d^2-5cd+2[/tex]

[tex]=4c^2+c^2+4cd+3cd-5cd+4d^2-d^2-5d^2+12+1-30+2[/tex]

We have given in the question that,

[tex]\bold{\underline{ To \: Find }}[/tex]

[tex]\bold{\underline{ Let's \: Begin }}[/tex]

Let the two numbers be x and y

According to the question,

[tex]\sf{ x + y = 11......eq(1) }[/tex]

[tex]\sf{ x - y = 19......eq(2) }[/tex]

Solving eq( 1 ) we get :-

[tex]\sf{ x + y = 11 }[/tex]

[tex]\sf{ x = 11 - y ......eq(3 ) }[/tex]

Subsituting eq(3 ) in eq(2) :-

[tex]\sf{ x - y = 19 }[/tex]

[tex]\sf{ ( 11 - y) - y = 19 }[/tex]

[tex]\sf{ 11 - y - y = 19 }[/tex]

[tex]\sf{ 11 - 2y = 19 }[/tex]

[tex]\sf{ - 2y = 19 - 11 }[/tex]

[tex]\sf{ - 2y = 8}[/tex]

[tex]\sf{ y = 8/(-2) }[/tex]

[tex]\sf{ y = - 4 }[/tex]

[tex]\sf{\red{Thus ,\: the\: value\: of \: y = -4}}[/tex]

Now, Subsitute the value of y in eq( 3 ) :-

[tex]\sf{ x = 11 - y }[/tex]

[tex]\sf{ x = 11 - (-4 ) }[/tex]

[tex]\sf{ x = 11 + 4 }[/tex]

[tex]\sf{ x = 15 }[/tex]

Hence, The value of x and y are 15 and (-4) .

The shape of the cross-section is rectangle, 8 inches by 4 inches.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

Now, from the figure we cut the figure from red line.

As the figure is a three dimensional figure called Cuboid.

We know that cuboid is formed by rectangle surfaces.

Then, the shape of the cross-section is Rectangle whose length is 8 inches and width 4 inches.

Volume is the space occupied by an object. The volume of the globe is 268.0825 in³.

The volume of the sphere is given by the formula,

[tex]\text{Volume of Sphere}= \dfrac{4}{3} \pi r^3[/tex]

We know that the diameter of the globe is reduced to half, therefore, the diameter of the globe,

[tex]\rm \text{New Diameter of the globe} = \dfrac{Diameter}{2} = \dfrac{16}{2} = 8\ inches[/tex]

Also, the radius of the globe is half of its diameter,

[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{8}{2} = 4\ inches[/tex]

We know that the shape of a globe is spherical, also, we know the formula of the volume of the sphere, therefore, the volume of the globe can be written as,

[tex]\begin{aligned}\text{Volume of Globe}&= \dfrac{4}{3} \pi r^3\\\\& =\dfrac{4}{3} \pi (4)^3\\\\&=268.0825\rm\ in^3 \end{aligned}[/tex]

Answer:

There are 50 large boxes.

There are 65 small boxes

Step-by-step explanation:

First, "boxes of two sizes" means we can assign variables:

  Let x = number of large boxes

       y = number of small boxes

 "There are 115 boxes in all"    means    x + y = 115      [eq1]

Now, the pounds for each kind of box is:

    (pounds per box)*(number of boxes)

So,pounds for large boxes     +    pounds for small boxes      =    4125 pounds"the truck is carrying a total of 4125 pounds in boxes"

        (50)*(x)                   +              (25)*(y)                  = 4125    [eq2]

It is important to find two equations so we can solve for two variables.

Solve for one of the variables in eq1 then replace (substitute) the expression for that variable in eq2.  Let's solve for x:

   x = 115 - y          [from eq1]

 50(115-y) + 25y = 4125             [from eq2]

 5750 - 50y  + 25y = 4125           [distribute]

 5750 - 25y = 4125

 -25y = -1625

    y = 65   [divide both sides by (-25)]

  There are 65 small boxes.

Put that value into either equation (now, which is easier?) to solve for x:

  x = 115 - y

  x = 115 - 65

  x = 50

  There are 50 large boxes.

Add up to get the total number of marbles: (8 + 6 + 12 + 10) = 36

Then subtract the number of blue marbles from the total amount of marbles: 36 - 8 = 28.

28 signifies the amount of marbles that are NOT blue.

So the probability is: 28/36 = 0.77 = About 77%

The final answer is 7/9.
