Answer:

Let x equal the ice thickness. An equality that represents a safe ice thickness for walkability is:

x ≥ 4 inches

(Plus the graph)

Step-by-step explanation:

Defining a variable just means you let any letter or symbol take the place of something. But you have to specifically say what is what in order for it to be clear.

So I defined "x" as the variable to represent the ice's thickness. And since we want an inequality for all the safe thicknesses, we could say that "x" must be greater than or equal to 4 inches thick in order to safely walk on it.

Lastly, you'd graph it with a solid point on 4 with the arrow going to the right.

Answer:

0.6

Step-by-step explanation:

We know that there are 5 counters in total. 3 white and 2 black.

So we know that 3 out of 5 are white and 2 out of 5 are black.

Therefore the chance to get white is 3/5. And for black: 2/5.

We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)

And 2/5 = 0.4 (You can make it 4/10 to make it easier.)

Answering the question, you should put your cross/marker on 0.6

How much simple interest is earned on $6000 principal, with an annual interest rate of 3.7% over 5 years?

diamong [38]

I = PRT
P (principal) = 6000
R (rate) = 3.7%.....u need decimal form = 0.037
T (time) = 5

I = (6000)(0.037)(5)
I = 1110.00 <===

u dont need years as a decimal...u need rate as a decimal

A cone and a sphere both have a radius of 1. If you fill the cone with liquid, and pour it into the sphere, it fits exactly. Wha

PtichkaEL [24]

Answer and Step-by-step explanation:

First, solve for the volume of the sphere, then solve for the height of the cone using the volume of the sphere (which is said to be equal to the volume of the cone) and the radius given.

Volume formula of Sphere

V = $\frac{4}{3} \pi r^2$
