Mandarinka [93]3 years ago
8 0

Answer: One of them is the set {1,2,3,4,5,6}itself; one is the empty set, containing no elements. “Proper subset of a set ” usually denotes a subset in which at least one element of the original set is missing; so one of the subsets - the original set iitself - is not a proper subset. Therefore the answer is 63.

The distance (d) in meters that an ant can travel varies directly with the amount of time (t) in hours it spends walking.assume
Assoli18 [71]

Answer:  d=18t

Step-by-step explanation:

By definition, Direct proportion equations have the following form:

y=kx

Where "k" is the constant of proportionality.

In this case you know that the distance (in meters) that an ant can travel varies directly with the amount of time (in hours) the ant spends walking.

With this information you can write the following equation:

d=kt

According to the exercise, the constant of proportionality is:

k=18

Therefore, substituting the value of the constant of proportionality into the equation, you get that  the equation that represents the proportional relationship between "d" and "t" is:

d=18t

Find the missing side for each triangle below
xxTIMURxx [149]

Applying the Trigonometry ratio, CAH, the missing side is, x = 1.9.

<h3>How to Solve a Right Triangle Using Trigonometry Ratio</h3>

The Trigonometry Ratios are:

  • SOH - sin∅ = opp/hyp.
  • CAH - cos∅ = adj/hyp.
  • TOA - tan∅ = opp/adj.

Thus, given:

∅ = 51°

hyp = 3

adj = x

  • Apply, CAH:

cos 51 = x/3

x = (cos 51)(3)

x = 1.9

Thus, applying the Trigonometry ratio, CAH, the missing side is, x = 1.9.

HELP ME PLEASE!!!!!!! What is the volume of the cube?
tatiyna
The answer is A. 3375 mm^3. This is because, since it is a cube, all of the sides are the same, meaning that you have to do 15 × 15 = 225, and then multiply that by 15 which is 3375. I hope this helps!
