Answer:
<h3>Question 1</h3>
- Let number of adult tickets - x, student tickets - y
<u>Required equations:</u>
- x + y = 8
- 7.25x + 5.50y = 52.75
<u>Solve by substitution x = 8 - y</u>
- 7.25(8 - y) + 5.50y = 52.75
- 58 - 7.25y + 5.50y = 52.75
- 1.75y = 5.25
- y = 5.25/1.75
- y = 3
<u>Find x:</u>
Answer: 5 adults and 3 students
<h3>Question 2</h3>
- Pair of gloves costs- x, hats cost- y
<u>Equations:</u>
<u>Solve by elimination, subtract the equations:</u>
- 2y = 43 - 30
- 2y = 13
- y = 6.5
<u>Find x:</u>
- 2x = 30 - 13
- 2x = 17
- x = 8.5
Answer: Gloves cost $8.5, hats cost $6.5
Given that median area is 15 square units.
Hence rectangle C in the middle has 15 square units.
Its dimensions can be width= 5 and length = 3
SInce B is smaller than C and has the same length, B has lengh of 3 with area = 9 sq units.
D has the same perimeter = 16 units. Since D is a square, side of D = 4 units.
Now D and E have the same length. Hence length of E = 4 units.
Width of E = width of C = 5 units.Thus makes the area of E as 20 sq units.
Rectangle A has length =3 and width can be less than 3 since area is smaller than B.
so A has length= 3 width = 2 with area = 6 sq units.
All Real Numbers that are NOT Rational Numbers; cannot be expressed as
fractions, only non-repeating, non-terminating decimals
−√2 , −√5 3 , √21, √81 3 , √101
*Even roots (such as square roots) that don’t simplify to whole numbers are irrational.
Answer:
M = (6, 8)
Step-by-step explanation:
To the find the midpoint of a segment you add the x values, then divide by 2, then add the y values and divide by 2. 
. Therefore, you would do ((4+8)/2, (9+7)/2). So, you're answer is (12/2, 16/2), which equals (6, 8)
1meter=1000milimeter
1meter=100centimeter
1000milimeter=100centimeter
1cm=10mm
1cm^3=1000mm^3
8000mm^3 * 1cm^3/(1000mm^3) = 8 cm^3
hopes this gains.
