Hope this helped Mark BRAINLIEST!!!

Answer 2

The number of figures has at least one vertex is 2. Therefore, option C is the correct answer.

What is a vertex?

A vertex is a point in geometry where two or more curves, lines, or edges converge. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedral.

From the given figure,

Sphere: Spheres have no vertex (the surface is a curve).

Triangular pyramid: Triangular pyramid has 5 vertex, 4 faces and 6 edges

Cube: Cube has 8 vertex, 6 faces and 8 edges.

Cylinder: A cylinder has 0 vertices. A cylinder has 2 edges. A cylinder has 2 faces and 1 curved surface.

Therefore, option C is the correct answer.

Hello there!

The slopes of perpendicular lines are opposite reciprocals.

So, if one line has a slope of 4, then the slope of the line perpendicular to it is the opposite of 4 flopped over (-1/4)

A box is being packed with cubes that measure 1 cubic foot. What is the volume of the box in cubic feet

Answers

Answer:

81 cubic foot

Step-by-step explanation:

It is given that the box is packed with cubes whose side is 1 foot. So the volume of one cube is 1 cubic foot.

Now from the figure, we can see that :

Number of cubes fitting the box across its length = 9 cubes

Number of cubes fitting the box across its width = 3 cubes

Number of cubes fitting the box across its height = 3 cubes

And each of these cubes measures 1 x 1 x 1 cubic foot

So the volume of the box can be found out by:

Volume = length x width x height

= 9 x 3 x 3

= 81 cubic foot

Therefore volume of the box is 81 cubic foot.

Mandy runs 4 km in 18 minutes. She plans to run in a 16 km race. Based on her current speed. how long will it take her to complete the race

Answers

Answer:

72 minutes

Step-by-step explanation:

You need to set up 2 fractions and set them equal to one another to be able to solve this.

Equation: 4km/18min = 16km/x min

You need to find x. In order to do this you can use that butterfly method/cross multiplication. You do 4 times set equal to 18*16.

Next, you get 18*16=288 and you must divide the other side (4x) to get your final answer. So, 288/4= 72 minutes.

John buys an item that costs $50.00 is marked 20% off. Sales tax for the item is 8%. What is the final price that John pays, including tax?

Answers

Answer:

$43.20

Step-by-step explanation:

20% of $50.00 is $10.00. $50 - $10 is $40. 8% of $40 is $3.20. Since this is tax, you must add it. $40+$3.20 = $43.20

The dimensions of two square pyramids formed of sand are shown. How much more sand is in the pyramid with the greater volume?

I will ONLY give brainliest to whoever answer FIRST AND whoever answers CORRECTLY!

Answers

Answer:

There is 32in² more sand in the pyramid with greater volume.

Step-by-step explanation:

Volume of rectangular pyramid = l²*h/3, where l is the base length and h is height.

Volume of left pyramid=l²*h/3=8²*(6/3)=64*(2)=128in³

Volume of right period=l²*h/3=6²*(8/3)=36(8/3)=96in³

128-96=32, there is 32in² more sand in the pyramid with greater volume.
