Its a solid and a cube

You were wrong with square because a square only has one face while a cube has 6.

You were also wrong with polygon because while polygons are 1-dimensional a cube is 3-dimensional

The following terms correctly describe the given object Square, Solid, Cube, Polygon.

Options A, B, C, D are correct.

A cube is a 3-D solid shape, which has 6 faces. A cube is one of the simplest shapes in three-dimensional space. All the six faces of a cube are squares, a two-dimensional shape.

Square is a figure in which all four sides are equal.

Solid is a three dimensional figure.

A Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges.

Polygon is two dimensional figure with straight lines.

Answer:

about 180

Step-by-step explanation:

(when rounding, numbers 0-4 "stay" meaning you'd round down. If the numbers are 5-9, you round up)

91 rounded to the nearest ten would be 90

94 rounded to the nearest ten would be 90 as well

So, 90 + 90 = 180

Technically though, 91+94 = 185. So rounding this to the nearest ten would be 190.

Step-by-step explanation:

Answer:

79=23+8h

or,79-23=8h

or,56/8=h

or,7=h

therefore the value of h is 7.

Step-by-step explanation:

Hope it helps you!!

first you have to do the 23+ you have to make 23 into a subtraction problem in these expressions. 79-23= 56

Now you have to cancel out the 8in 8h and do the opposite of multiplication and do division on both sides 8h/8 cancels out and 56 divided by 8 = 7

your answer is 7 hope this helps

Answer:

The total volume of the glass is 300 cm^3.

Step-by-step explanation:

Let V represent the total glass volume.

Then (4/5)V - (2/3)V = 40 cm^3.  The LCD here is 15, so we rewrite this equation as

(12/15)V - (10/15)V = 40 cm^3, or

(2/15)V = 40 cm^3.

Solve for V by multiplying both sides of this equation by (15/2):

(15/2)(2/15)V = (15/2)(40  = 300 cm^3

The total volume of the glass is 300 cm^3.

Answer:

x = 25

y = 65

Step-by-step explanation:

I'm not sure if I'm right but..

To solve x:

Since there is a 90 degree angle with 65 degrees and x, the total should sum up to 90. (ofc)

90 - 65 = 25 <--- the missing angle (x)

To solve y:

I'm pretty sure that it is also a 90 degree angle because there is a 90 degree across from you, so they should have the same angles. Since you know x=25, You would do this:

90 - 25 = 65 <--- y

Your welcome!!

Answer:

69 pi is your answer.

Answer:

x = 90

Step-by-step explanation:

If x = 3 and y = 4 then when y = 120 just find out what times 4 = 120

which is 30.

so just multiply 30 for x = 3, then the answer will be 90

x = 90

Answer:

x=90

Step-by-step explanation:

x is directly proportional to y

Therefore, if the initial y value was 4 and the final y value is 120. This means that y initial had been multiplied 120/4 times, which is 30.

Same goes for x. If x initial is 3, then the final x value would be x/3=30. This means that x=3×30, which is equal to 90.
