What else can I help you with?
In a box of 39 buttons 25 have 4 holes 18 are red and 13 have 4 holes and are also red so how many buttons have 4 holes and are not red?
their are a total of 39 14 have no holes at all 25 have 4 holes, 18 of wich are red but only 13 of them have 4 holes so thiers 5 red without holes that leave the other 7 with 4 holes.
What is the formula for pcd dia 100 for 8 holes?
The formula to calculate the Pitch Circle Diameter (PCD) for a given number of holes is: [ \text{PCD} = \frac{d}{\sin\left(\frac{180^\circ}{n}\right)} ] where ( d ) is the distance between holes (or the diameter of the circle on which the holes are located), and ( n ) is the number of holes. For a PCD of 100 mm with 8 holes, you would use this formula to determine the spacing and arrangement of the holes around the circle.
What is the word that means to make holes through?
We can punch or perforate materials to make holes.
What is Four holes and one half as a decimal?
Assuming that you do not mean holes but wholes(!), the answer is 4.5
How many holes are there per square inch in a sieve set?
The size of the holes in a sieve depends on what is the the size of material to be allowed through the holes. A set of sieves (flour sieves, garden riddles, etc) will range from large holes to fine.
What is the significance of octahedral holes in crystal structures?
Octahedral holes in crystal structures are important because they provide spaces where certain atoms or ions can fit, helping to stabilize the overall structure of the crystal. These holes play a key role in determining the physical and chemical properties of the crystal, such as its density, hardness, and conductivity.
What is the arrangement of atoms in a crystal lattice that allows for the presence of both tetrahedral and octahedral holes?
The arrangement of atoms in a crystal lattice that allows for the presence of both tetrahedral and octahedral holes is known as a close-packed structure. This structure consists of layers of atoms packed closely together in a repeating pattern, creating spaces where smaller atoms can fit into either tetrahedral or octahedral positions.
What type of holes are therein body centered cubic?
There are no holes in the body-centered cubic (BCC) structure, as it consists of atoms positioned at the corners and one atom at the center of the cube.
What note is it that you play on the bassoon when all the holes are closed?
When all of the holes are closed, the note is a A. It may also be a B,I am not positive
What are bong holes?
Bong holes might refer to the holes that are in the pipe portion of a water bong that is used to smoke herbal tobacco. Bung holes are the holes in wine barrels that are closed with corks.
What flame is what you called when air holes are closed?
Safety flame
What are the differences between a tetrahedral hole and an octahedral hole in crystal structures?
In crystal structures, a tetrahedral hole has four neighboring atoms or ions surrounding it, while an octahedral hole has six neighboring atoms or ions surrounding it. This difference in coordination number affects the size and shape of the holes, as well as the types of ions that can fit into them.
Is a sponge open or closed?
it has lots of holes which need filling... if you know what i mean
How does air goes out of a tightly closed balloon?
It gradually leaks out. There are tiny holes in the balloon's skin.
How soon after having your wisdom teeth pulled should you clean out the holes?
The holes are actually stitched closed. So there aren't actually any holes. Don't go poking around where the teeth were, you might cause an infection.
Could you pierce your ears in a already closed hole?
Yes but it's better to reopen the closed holes with an insertion taper in the hands of an experienced professional body piercer.
Do black whales have blow horns?
Yes, black whales do have blow holes. They keep them closed when they are underwater.
