Answer:
-7/8
Step-by-step explanation:
change the denominator and numerator of -1/2 by multiplying both by 4.
Then you get -4/8 instead of -1/2. This allows you to then subtract the -3/8 with -4/8 which equals -7/8.
3/5 + 1/2 in simplest form

Answer:
1) Bigger sector = 168.8pi
1) Smaller sector = 56.3pi
2) Bigger sector = 529.9
3) Smaller sector = 176.6
Step-by-step explanation:
1) Bigger sector = [tex]\frac{270}{360}[/tex]×pi×15×15
= 168.75pi
1) Smaller sector = [tex]\frac{360-270}{360}[/tex]×pi×15×15
= [tex]\frac{90}{360}[/tex]×pi×15×15
= 56.25pi
2) Bigger sector = [tex]\frac{270}{360}[/tex]×3.14×15×15
= 529.875
2) Smaller sector = [tex]\frac{360-270}{360}[/tex]×3.14×15×15
= [tex]\frac{90}{360}[/tex]×3.14×15×15
= 176.625
Use A Diagram To Show That (3x+1)(x+2) Is Equivalent To 3x2+7x+2. Show Your Work.
Is (x+4) Equivalent To 2x2+8x+8? Explain Or Show Your Reasoning.
Answer:
1) Please find attached the diagram showing the answer to the question
The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares
∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2
2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18
Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8
Step-by-step explanation:
1) In the attached diagram, we have;
For x = 1
(3x + 1)(x + 2) = (3 + 1)(1 + 2)
Therefore, the length of the sides of the rectangle are;
Height = 4, and Width = 3
For x = 1, x² = 1² = 1
∴ 3·x² = 3, 7·x = 7 × 1 = 7, and 2 = 2
Therefore, from the diagram, we have;
The area = (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares
∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2
The diagram for when x = 3 is also included
2) For (x + 4)², we have;
When x = 1, (x + 4)² = (1 + 4)² = 25
However;
When x = 1, 2·x² + 8·x + 8 = 2 × 1² + 8 × 1 + 8 = 18
Therefore;
(x + 4)² is not equivalent to 2·x² + 8·x + 8

What is 15 % converted into numbers, or 120$ increased by 15%
After the semester is over, you discover that the math department has changed textbooks (again) so the bookstore won't buy back your nearly-new book. You and your friend Anna decide to get creative. You go to the rook of a five-story building and look over the edge to the reflecting pool 60 feet below. You drop your book over the edge at the same instant that Anna chucks her book straight down at 30 feet per second. By about how many seconds does her book beat yours into the water (approximately)? Your function is s(t)=−16t2+60 Anna's function is s(t)=−16t2−30t+60
Answer:
0.78 s
Step-by-step explanation:
Since the position of the pool is at 60 feet below, s(t) = -60 for both me and Anna. So, both expressions for the motion of the book are equated to -60 and then solved to find the time they reach the water.
So, For me s(t)= −16t² + 60
-60 = −16t² + 60
collecting like terms, we have
-60 - 60 = −16t²
- 120 = −16t²
dividing both sides by - 16, we have
t² = -120/-16
t² = 7.5
t = √7.5
t = 2.74 s
For Anna, s(t)= −16t² - 30t + 60
-60 = −16t² - 30t + 60
adding 60 to both sides, we have
-60 + 60 = −16t² - 30t + 60 + 60
−16t² - 30t + 120 = 0
dividing through by -2, we have
8t² + 15t - 60 = 0
Using the quadratic formula to find t
[tex]t = \frac{-15 +/- \sqrt{15^{2} - 4 X 8 X -60} }{2 X 8} \\t = \frac{-15 +/- \sqrt{225 + 1920} }{16} \\t = \frac{-15 +/- \sqrt{2145} }{16} \\t = \frac{-15 +/- 46.31}{16} \\t = \frac{-15 - 46.31}{16} or t = \frac{-15 + 46.31}{16} \\t = \frac{-61.31}{16} or t = \frac{31.31}{16} \\t = -3.83 s or 1.96 s[/tex]
Since t' cannot be negative, t' = 1.96 s.
It takes Anna's book 1.96 s to reach the water, while it takes 2.74 s for my book to reach the water.
So, the time it takes Anna's book to beat mine is the difference between the time of reaching the water of each book. So Δt = t - t' = 2.74 s - 1.96 s = 0.78 s

1. 10 − 6 x = 4 + 5 x
2. 7-6x=1+5x
Answer:
1. After solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]
2. After solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]
Step-by-step explanation:
We need to Solve the equations.
1. [tex]10 - 6 x = 4 + 5 x[/tex]
Step 1: Subtract 5x on both sides
[tex]10 - 6 x-5x = 4 + 5 x-5x\\10-11x=4[/tex]
Step 2: Subtract 10 on both sides
[tex]10-11x-10=4-10\\-11x=-6[/tex]
Step 3: Divide both sides by -11
[tex]\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}[/tex]
So, after solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]
2. [tex]7-6x=1+5x[/tex]
Step 1: Subtract 5x on both sides
[tex]7 - 6 x-5x = 1 + 5 x-5x\\7-11x=1[/tex]
Step 2: Subtract 7 on both sides
[tex]7-11x-7=1-7\\-11x=-6[/tex]
Step 3: Divide both sides by -11
[tex]\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}[/tex]
So, after solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

Given: a and b are parallel and c is a transversal. Prove: ∠2 ≅ ∠7 Parallel lines b and a are cut by transversal c. On line b where it intersects with line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 5, 6, 2. On line a where it intersects with line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 3, 7, 8, 4. Use the drop-down menus to complete the paragraph proof showing that alternate interior angles are congruent. We know that lines a and b are parallel and that line c is a transversal because that is given. We can tell that angles 2 and 5 are congruent because angles are congruent. Angles 5 and 7 are congruent because angles by parallel lines cut by a transversal are congruent. Therefore, angles 2 and 7 are congruent based on the
