Which property is best to use when determining the strength of an ionic bond in a solid?

Shtirlitz [24]

I think the best property to use is electronegativity since that is how much it attracts/wants electrons. The larger the difference in electronegativity is between two atoms, the stronger the ionic bond will be. This is also why two atoms need to have a minimum difference between the electronegativity to be considered ionic and not covalent.

7c??? help on 7c???? please?!

Salsk061 [2.6K]

It would be a 12.5% increase. First you find her monthly wages: $10.50 x 160 hours= $1680 a month. Her insurance is $210/month. So you need to find what percentage 210 is of 1680. So $1680*x=210$ . Solve for x by dividing 1680 on both sides and you get 0.125. Multiply by 100 to get the percentage and you get 12.5%. Check your answer by multiplying 1680 x 0.125 and you get 210.

Sam volunteers at an animal shelter. He created a line plot to show the weights in pounds of the kittens at the shelter.

Anastaziya [24]

Answer:

The total weight is 5kg

Step-by-step explanation:

Given

See attachment for box plot

Required

Determine the total weight of the kitten

First, we represent the plot in the following table where the number of dots represent the frequency.

So, we have:

$Weight \to Frequency$

$\frac{1}{2} \to 3$

$1 \to 2$

$1\frac{1}{2} \to 1$

$2 \to 0$

$2\frac{1}{2} \to 0$

Multiply the weight by the frequency, then add up the result

So, we have:

$Total = \frac{1}{2} * 3 + 1 * 2 + 1\frac{1}{2} * 1 + 2 * 0 + 2\frac{1}{2} * 0$

$Total = 1\frac{1}{2} + 2 + 1\frac{1}{2} + 0 + 0$

$Total = 1\frac{1}{2} + 2 + 1\frac{1}{2}$

Express as improper fraction

$Total = \frac{3}{2} + 2 + \frac{3}{2}$

Take LCM

$Total = \frac{3+4+3}{2}$

$Total = \frac{10}{2}$

$Total = 5kg$

A conical paper funnel of radius 4 and height 6 units is needed to make a good cup of coffee. If this funnel is made out of a se

Nimfa-mama [501]

Answer:

The radius of this circle is $2\sqrt{13}$ and the central angle of the sector is $\theta=\frac{2}{\sqrt{13}}\times360^\circ$ .

Step-by-step explanation:

Consider the provided information.

If a conical paper funnel is made out of a sector of circle then the radius of the sector becomes the slant height of the cone, and the length of the curved part of the sector becomes the circumference of the base of the cone.

First find the slant height: $l=\sqrt{r^2+h^2}$
