Answer:
im not sure i got stuck here ;; but i started sort of
Step-by-step explanation:
The first step is to get the inner angles. I'll start with the one at 60 degrees and call it A and go counter clockwise
A flat angle is 180 and -60 makes it 120 = Angle A
180-100=80=B
180-20=160=C
Then when you're trying to calculate a figure with more than 4 corners, you're supposed to divide them into triangles. Now we have a hexagon and the total degrees is 720. And we know that we have 2 6x and they're the angles

(d) Determine how many cups of punch the punch bowl will fill using Cup size B. Round the number of scoops to the nearest whole number, and make certain to show your work.
Can someone help me with this?
The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³
Volume
Volume is the amount of space occupied by a three dimensional object or figure.
The cup has the shape of a cylinder, the volume is:
Volume = π * radius² * height
For cup A:
Volume = π * (10/2)² * 20 = 1570.8 cm³
Let each punch be 1 cm³, the number of cups needed = 1570.8 cm³ / 1 cm³ = 1571
For cup B:
Volume = π * (20/2)² * 20 = 6283 cm³
Let each punch be 1 cm³, the number of cups needed = 6283 cm³ / 1 cm³ = 6283
The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

Answer:
Step-by-step explanation:
1) (y - 1)²
1. y*y =y²
2. 2(y)(-1)= -2y
3 . (1)(1) = 1
(y-1)² = y² - 2y + 1
2) (6y + 3)²
1. (6y)(6y) = 36y²
2. (2)(6y)(3)=36y
3. (3)(3) = 9
(6y + 3)² = 36y² + 36y + 9
3) (4x - y)²
1. (4x)(4x) = 16x²
2. (2)(4x)(-y) = -8xy
3. (y)(y) = y²
(4x -y)² = 16x² - 8xy + y²
4) (y - 12)²
1.(y)(y) = y²
2. (2)(y)(-12) = -24y
3. (12)(12) = 144
(y - 12)² = y² - 24y + 144

John can eat a melon 2 minutes faster than Sam can eat an identical melon. If they share one melon, they can eat it together in 2.4 minutes. How long does it take each of them to eat a melon?
Answer:
4 mins
Step-by-step explanation:
I guess not to sure ask teacher
Sam eats the melon in 0.2 minutes.
John eats the melon in 2.2 minutes.
What are the linear equations that represent this question?
x - y = 2 equation 1
x + y = 2.4 equation 2
Where:
x = minutes John eats the melon
y = minutes Sam eats the melon
How many minutes does John eat the melon?Add equation 1 and equation 2 together
2x = 4.4
Divide both sides by 2
x = 2.2
How many minutes does Sam eat the melon?
Substitute for x in equation 1
2.2 - y = 2
y = 2.2 2
y = 0.2 minutes

find f(2) given f(x) = 2x^2 + 5x - 21
Answer:
f(2) = -3
Step-by-step explanation:
Find f(2) given f(x) = 2x^2 + 5x - 21
Since on the left side, x is replaced by 2, on the right side, x should also be replaced by 2.
f2 = 2(2)² + 5(2) - 21
2 x 2² = 2 x 4 = 8
5 x 2 = 10
8 + 10 = 18
18 - 21 = ?
-(21 - 18 = 3)
-21 + 18 = -3
f(2) = -3

The admission fee at an amusement park is $1.25 for children and $6.60 for adults. On a certain day, 342 people entered the park, and the admission fees collected totaled $1337. How many children and how many adults were admitted
Let's imagine all the tickets were for children.
The fees collected would've been 342 x 1.25 = $427.5
That is 1337 - 427.5 = $909.5 less than the actual fees.
Everytime we switch 1 children ticket to an adult ticket, the gap goes down 6.60 - 1.25 = 5.35
For example, if 341 tickets were children tickets, and 1 is adult, the gap go from 909.5 to 904.15.
We do this until the gap becomes 0... So, there are 909.5 : 5.35 = 170 adult tickets
And there are 342 - 170 = 172 children tickets
Recheck : 172 x 1.25 + 170 x 6.6 = 215 + 1122 = 1337.

Answer:
x=2
Step-by-step explanation: 1.2x-5.2=-2.4x+2. First, you add 2.4x to 1.2x to get x isolated. So now it's 3.6x-5.2=2. Then add 5.2 to 2 to isolate x. Now you have 3.6x=7.2 now you divide 7.2 by 3.6 to get x=2.
Answer:
x=2
Step-by-step explanation:
1.2x-5.2=-2.4x+2
multiply 10
12x-52=-24x+20
refine and add 52
12x=-24x+72
add 24x
36x=72
divide 36

Error Analysis A gardener plans to extend the length of a rectangular garden by 7 feet. Letx represent the garden's original length. The expression 9(x + 7) represents the area of the garden, where 9 is the width, in feet, and (x + 7) represents the extended length, in feet, of the garden When asked for the area of the extended portion, the gardener incorrectly said it was 16 square feet. Expand the expression to find the area of the extension.
Answer:
9(x+7)
Distribute the 9 by multiplying it to x and 7
9x+63
The area of the extension is 63.
The gardener added 9 and 7 instead of multiplying.
What is the value of x when h(x) = -3?

O. -1
О.0
O. 2
Answer:
O. -1
Step-by-step explanation:
We can look at the graph given to see the value of -3.
When h(x) = -3, it means that the y value is equal to -3. We see that, on the graph, when y = -3, x = -1.
What is the greatest common factor of 12 and 30
Answer:
6
Step-by-step explanation:
We know if we multiply 6x2=12 and 6x5=30. After 6 you can not multiply anything else higher than that. For example 15x2=30 but 15 is not a GCF of 12 and 4x3=12 3 and 4 are not GCFs of 30. So 6 is the GCF of 12 and 30.
