Hey! The drink was $1.15 because $10 minus the cost of the lunch ($7.75), tax (0.47), and what was given back in change (0.63) leaves you with $1.15
Answer:
32
Step-by-step explanation:
(4x6)/2+(2x2)/2+2x2+(2x6)/2
In a triangle, the measure of an angle is in the same order of size as the length of the opposite side. The smallest angle is opposite the shortest side. The largest angle is opposite the longest side. The middle-sized angle is opposite the middle-sized side.
Also, in a triangle, the sum of the measures of the interior angles is 180.
We can now calculate the measures of the three angles by writing and solving an equation.
m<A + m<B + m<C = 180
9x - 7 + 7x - 9 + 28 - 2x = 180
Collect like terms on the left side.
9x + 7x - 2x - 7 - 9 + 28 = 180
14x + 12 = 180
Subtract 12 from both sides.
14x = 168
x = 12
Now that we know x, we can find the measure of each angle.
m<A = 9x - 7 = 9(12) - 7 = 108 - 7 = 101
m<B = 7x - 9 = 7(12) - 9 = 84 - 9 = 75
m<C = 28 - 2x = 28 - 2(12) = 28 - 24 = 4
(Quick check: Add the angles measures: 101 + 75 + 4 = 180. The sum is 180 as it should be.)
Now that we know the angle measures, the opposite sides are in the same order of size.
AB < AC < BC
The sides are, in increasing order of length:
AB, AC, BC
A solid whose top and base are congruent polygons and lateral faces are parallelograms is called <u>prism</u>.
<h3>
What is prism?</h3>
A prism is a polyhedron made up of n parallelogram faces that connect the n-sided polygon basis, the second base, which is a translated duplicate of the first base, and the n faces. Translations of the bases are found in all cross-sections that are parallel to them.
<h3>What is
congruent polygons?</h3>
If the corresponding sides and angles of two polygons are identical, then the polygons are congruent. It should be noted that two sides are congruent if their lengths are the same, and that an angle is congruent if its measure is the same.

I understand that the question you are looking for is:
A solid whose top and base are congruent polygons and lateral faces are parallelograms is called _____.
A. prism
B. polyhedron
C. sphere
D. cone
Answer:
is the better unit price.
Step-by-step explanation:
120 is the better unit price because if you divide 120 divided by 6 you get 20 and if you divide 200 divided by 8 you get 25 so then you would pick the cheapest one because of its price and amount.
