The parallelogram pictured below has a perimeter of 129. Find the value of y.
Answer:
y = 2½ = 2.5
Step-by-step explanation:
From the question given above, the following data were obtained:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
The perimeter of a parallelogram can be obtained by using the following formula:
Perimeter = 2(a + b)
Thus, with the above formula, we can obtain the value of y as shown below:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
Perimeter = 2(a + b)
Perimeter = 2a + 2b
129 = 2(10y – 9) + 2(17y + 6)
Clear bracket
129 = 20y – 18 + 34y + 12
Collect like terms
129 + 18 – 12 = 20y + 34y
135 = 54y
Divide both side by the coefficient of y i.e 54
y = 135/54
y = 2½ = 2.5
Thus, the value of y is 2½ or 2.5

An isosceles triangle is a two-dimensional figure which has two equal sides and the two angles opposite to the equal sides are equal.
The sum of the three angles is equal to 180 degrees.
The value of angle m∠Y is 34°.
Option B is the correct answer.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Isosceles triangle:
Two sides are equal.
The angles opposite to the equal sides are also equal.
So,
From the figure we have,
6x - 23 = 4x + 9
Add 23 on both sides.
6x - 23 + 23 = 4x + 9 + 23
6x = 4x + 32
Subtract 4x on both sides.
6x - 4x = 4x + 32 - 4x
2x = 32
Divide both sides by 2.
x = 32/2
x = 16
The sum of the three angles of the Isosceles triangle given must be 180 degrees.
6x - 23 + 4x + 9 + m∠Y = 180
Put x = 16
6x16 - 23 + 4x16 + 9 + m∠Y = 180
96 - 23 + 64 + 9 + m∠Y = 180
146 + m∠Y = 180
Subtract 146 on both sides.
m∠Y = 180 - 146
m∠Y = 34
Thus,
The value of angle m∠Y is 34°.
Option B is the correct answer.

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. What is the unit rate at which Martin paints in wall per gallon?
35/25
1 7/25
1/2
1 3/32
Answer:
Since your answer needs to be in walls per gallon I would assume you divide 4/5 by 5/8 since that would tell you how many walls he can paint in an hour.
4/5 walls÷5/8 gallons=1.28walls/gallon.

Lin-Manuel runs a rare book store. Last year, he earned $35,000 in revenue and had explicit costs of $8,000. Lin-Manuel could have made $29,750 testing information security equipment and received an additional $10,000 if he had used the company's inputs in a different way. Calculate Lin-Manuel's economic profit.
Answer: Economic loss of $12,750
Step-by-step explanation:
Economic profit is calculated by deducting both the implicit and the explicit costs from income.
Explicit cost are the costs of running the business whilst implicit costs are the gains that could have been earned if other alternatives had been embarked on.
Economic profit (loss);
= 35,000 - 8,000 - 29,750 - 10,000
= (12,750)

1) true or false: Two triangles with three pairs of corresponding congruent angles are congruent.
2) true or false: Two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent.
Step-by-step explanation:
TrueFalseFor two triangle to be congruent,there must be any three sides or angle including congruent
Congruent triangles have three pairs of corresponding sides that are congruent, while two triangles that have three pairs of corresponding congruent angles are similar and not necessary congruent. Therefore:
Statement 1 is FALSE.Statement 2 is TRUE.Recall:
Two triangles having three pairs of corresponding sides have the same shape and size, and are congruent.Two triangles having three pairs of corresponding angles have the same shape but may have different sizes. They are rather similar.1. When the two triangles have the three pairs of corresponding angles that are congruent, they can only be said to be similar. They have the same shape but may be of different sizes.
They will be congruent if all corresponding three pairs of sides of both triangles are congruent.Therefore, statement 1 is FALSE.
2. Knowing that three pairs of corresponding sides of two triangles are congruent, it is enough to prove that both triangles are congruent to each other.
Therefore, statement 2 is TRUE.

m/4 - 3 = 6 + m/2
Answer:
m = -36
Step-by-step explanation:
Solve for m:
m/4 - 3 = m/2 + 6
Hint: | Put the fractions in m/4 - 3 over a common denominator.
Put each term in m/4 - 3 over the common denominator 4: m/4 - 3 = m/4 - 12/4:
m/4 - 12/4 = m/2 + 6
Hint: | Combine m/4 - 12/4 into a single fraction.
m/4 - 12/4 = (m - 12)/4:
(m - 12)/4 = m/2 + 6
Hint: | Put the fractions in m/2 + 6 over a common denominator.
Put each term in m/2 + 6 over the common denominator 2: m/2 + 6 = m/2 + 12/2:
(m - 12)/4 = m/2 + 12/2
Hint: | Combine m/2 + 12/2 into a single fraction.
m/2 + 12/2 = (m + 12)/2:
(m - 12)/4 = (m + 12)/2
Hint: | Make (m - 12)/4 = (m + 12)/2 simpler by multiplying both sides by a constant.
Multiply both sides by 4:
(4 (m - 12))/4 = (4 (m + 12))/2
Hint: | Cancel common terms in the numerator and denominator of (4 (m - 12))/4.
(4 (m - 12))/4 = 4/4×(m - 12) = m - 12:
m - 12 = (4 (m + 12))/2
Hint: | In (4 (m + 12))/2, divide 4 in the numerator by 2 in the denominator.
4/2 = (2×2)/2 = 2:
m - 12 = 2 (m + 12)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the right hand side:
m - 12 = 2 m + 24
Hint: | Move terms with m to the left hand side.
Subtract 2 m from both sides:
(m - 2 m) - 12 = (2 m - 2 m) + 24
Hint: | Combine like terms in m - 2 m.
m - 2 m = -m:
-m - 12 = (2 m - 2 m) + 24
Hint: | Look for the difference of two identical terms.
2 m - 2 m = 0:
-m - 12 = 24
Hint: | Isolate terms with m to the left hand side.
Add 12 to both sides:
(12 - 12) - m = 12 + 24
Hint: | Look for the difference of two identical terms.
12 - 12 = 0:
-m = 24 + 12
Hint: | Evaluate 24 + 12.
24 + 12 = 36:
-m = 36
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of -m = 36 by -1:
(-m)/(-1) = -36
Hint: | Any nonzero number divided by itself is one.
(-1)/(-1) = 1:
Answer: m = -36
