Student Council sells bottled water at the cheerleading completion. At this rate, how many cases of bottled water would they sel
amid [387]

Answer:

27

Step-by-step explanation:

Lets find the rate of selling:

Let v= the rate of selling, b = number of bottles of water, and t = time:

b over t gives us the v=\frac{b}{t}=\frac{3}{20}=\frac{6}{40}=0.15 rate of selling:

3 hours is 60min * 3 = 180 mins, and since v=b/t, vt=b:

(0.15) * 180 = 27 bottles of water

Which additional information could be used to prove that the triangles are congruent using AAS or ASA? Check all that apply.
Ad libitum [116K]

Consider the given triangles.

Given: \angle C \cong \angle Q

ASA congruence criterion states that if two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

AAS congruence criterion states that if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Consider the first part:

1. In triangles ABC and QPT

If we take \angle B \cong \angle P , BC \cong PQ along with the given condition.

Then the triangles are congruent by ASA congruence criterion.

2. If we take \angle A \cong \angle T and AC= TQ=3.2 along with the given condition.

Then the triangles are congruent by ASA congruence criterion.

3. As,\angle C \cong \angle Q, \angle A \cong \angle T and \angle B \cong \angle P, so the triangles can not be congruent.

4. If we take \angle A \cong \angle T and BC \cong PQ along with the given condition.

Then the triangles are congruent by AAS congruence criterion.

5. If we take AC=TQ=3.2 and CB=QP=3.2 along with the given condition, then the triangles are congruent but by SAS congruence criteria neither by ASA nor AAS congruence criterion.

The sum of three consecutive numbers is 267.what is the largest number
iris [78.8K]
Rather than trial and error, you can do this with an equation.

x + x+1 + x+2 = 267 =>
3x+3 = 267
x = 264/3 = 88

So the numbers are 88+89+90. 90 is the largest number.

PLZ AMWSER, find the area for the circle, will mark brainest, plz tell me what u did to get the ANWSER
strojnjashka [21]

Answer:

area = 81π in² (or ≈ 254.47 in²)

Step-by-step explanation:

The formula for an area of a circle is  area = πr².

You are given the diameter, which is 18 in.

diameter = radius (2)

So to get radius, divide the diameter in half:

18/2 = 9.

Now that we have the radius, put that back into the formula for the area of a circle:

area= π9²

Then, solve for the 9², which will be 81 and put it back into the formula.

area = 81π in²

If you need to get rid of the π, the answer will be about 254.47 in²
