Since the perimeter of said hexagon is 120√3, we simply multiply this number by 10 and divide it by 2.
1200√3/2 = 600√3
A baker uses 4 cups of flour. She uses 1/4 cup to flour the counters and rest to make 8 identical muffins. How much flour is in each muffin? Answer must be in fractional form.
Answer:
15/32 cup
Step-by-step explanation:
Apparently, you're to assume that flour used on the countertop does not end up in the muffins. If that is the case, then the amount of flour in the 8 muffins is ...
4 cups - 1/4 cup = 3 3/4 cups
When that is divided evenly among 8 muffins, the amount in each is ...
(1/8)·(3 3/4 cups) = (1/8)·(15/4 cups) = 15/32 cup
Answer: 15/32
Step-by-step explanation: Because she uses 1/4 to flour the counter you need to subtract 1/4 from four which gives you 3 3/4. 3 3/4 divided by eight equals 15/32
Which of the following is a polynomial function in standard form with zeros at -8,-1 and 3? Help needed!!! 10 points!!! Math 3
ANSWER
[tex]f(x) = {x}^{3} + 6 {x}^{2} - 19 - 24[/tex]
EXPLANATION
The polynomial function has zeros at:
-8,-1 and 3
This means the polynomial can be factored as:
[tex]f(x) = (x + 8)(x + 1)(x - 3)[/tex]
We expand the last two factors:
[tex]f(x) = (x + 8)( {x}^{2} - 2x - 3)[/tex]
We expand further to get:
[tex]f(x) = {x}^{3} - 2 {x}^{2} - 3x + 8 {x}^{2} - 16x - 24[/tex]
[tex]f(x) = {x}^{3} + 6 {x}^{2} - 19 - 24[/tex]
The polynomial in descending powers of x is said to be in standard form.
What is the recursive formula for this geometric sequence
6, -24, 96, -384,...
Answer:
see explanation
Step-by-step explanation:
The recursive formula allows us to calculate the next term in the sequence from the previous term.
The common ratio r = [tex]\frac{-24}{6}[/tex] = - 4
Thus multiplying any term by - 4 gives the next term, that is
[tex]a_{n+1}[/tex] = - 4 [tex]a_{n}[/tex] with a₁ = 6
Which point is part of the solution of the inequality y<=|x+4|-3
The answer is: The point (0,0) is part of the solution.
Why?To find which point is part of the solution of the inequality, we need to evaluate each of the given points. If the inequality is satisfied, then the point is part of the solution, otherwise, if the inequality is not satisfied, the point is not part of the solution.
We are given the inequality:
[tex]y\leq |x+4|-3[/tex]
So, evaluating we have:
- First point (-2,1)
[tex]y\leq |x+4|-3\\\\1\leq |-2+4|-3\\\\1\leq |2|-3\\\\1\leq 2-3\\\\1\leq -1[/tex]
Now, since 1 is not less or equal to -1, the point (-2,1) is not part of the solution.
- Second point (1,3)
[tex]y\leq |x+4|-3\\\\3\leq |1+4|-3\\\\3\leq |5|-3\\\\3\leq 5-3\\\\3\leq 2[/tex]
Now, since 3 is not less or equal to 2, the point (1,3) is not part of the solution.
- Third point (-4,2)
[tex]y\leq |x+4|-3\\\\2\leq |-4+4|-3\\\\2\leq |0|-3\\\\2\leq 0-3\\\\2\leq -3[/tex]
Now, since 2 is not less or equal to -3, the point (-4,2) is not part of the solution.
- Fourth point (0,0)
[tex]y\leq |x+4|-3\\\\0\leq |0+4|-3\\\\0\leq |4|-3\\\\0\leq 4-3\\\\0\leq 1[/tex]
Now, since 0 is less than 1, the point (0,0) is part of the solution.
Hence, we have that the point (0,0) is part of the solution.
Have a nice day!

An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled using h(t) = 144 – 16t2. How many seconds will it take the object to reach the ground? second(s)
Answer:
t = 3 seconds
Step-by-step explanation:
We have the equation, as a function of time, that describes the height of the object that is dropped from the bridge.
The equation is:
[tex]h (t) = 144 - 16t ^ 2[/tex]
Where t is the time in seconds and h is the height in feet.
To know how long it takes the object to fall to the ground we do h (t) = 0 and solve for t.
So:
[tex]0 = 144 - 16t ^ 2\\\\16t ^ 2 = 144\\\\t ^ 2 = \frac{144}{16}\\\\t ^ 2 = 9\\\\t_1 = 3\\t_2 = -3[/tex]
We take the positive solution.
Therefore the object takes 3 seconds to reach the ground
Answer:
t=3 seconds

Which is an equation PLS HELP MEEEE
Answer:
It should be D if that is an option.
Step-by-step explanation:
The equation is y= -3/2 x + 3
The slope is -3/2. It goes down 3 and over 2 to the right.
The y-intercept is positive 3. It intersects with the y-axis at the point (3,0).
Answer:
y = -3/2x + 3
Step-by-step explanation:
To find the equation for the graph, first you must find the slope. Pick 2 random points on the line, [for example (2,0) and (0,3)] You can find the slope by using the formula rise/run [rise over run]. To get from point (2,0) to point (0,3) you have to go up 3 and left 2 [resulting in the negative infront of 3/2. if you went right, ti would've been positive.] Then you have your slope, -3/2x
Next find the y-intercept [the point where the line hits the y-axis]
The line hits the y-axis at (0,3), so your y-intercept s 3.
Therefore, the equation is -3/2x+3

There were two containers of oil. There was twice as much oil in the second container as in the first one. After using 13 liters of oil from the first container and 7 liters from the second one, the second container still had 3 times more oil than the first one. How many liters of oil in total were in both containers originally?
PleASE HELP
Answer:
There are 96 liters of oil in both containers originally
Step-by-step explanation:
* Lets change the story problem to mathematics equation
- Let the first container had A liters of oil and the second container
had B liters of oil
- The quantity of oil B in the second container is twice the quantity
of oil in A in the first container
∴ B = 2A ⇒ (1)
- After using 13 liters from the quantity of oil A in the first container,
the container had (A - 13) liters
- After using 7 liters from the quantity of oil B in the second container,
the container had (B - 7) liters
- After that the quantity of oil in the second container is 3 times
more oil than the first one
∴ B - 7 = 3(A - 13) ⇒ simplify
∴ B - 7 = 3A - 39 ⇒ add 7 and subtract 3A from both sides
∴ B - 3A = -39 + 7
∴ B - 3A = -32 ⇒ (2)
- Substitute the value of B from (1) into (2)
∴ 2A - 3A = -32
∴ -A = -32 ⇒ × -1
∴ A = 32 liters
- Find the value of B by substitute value of A in (1)
∴ B = 2(32) = 64 liters
- Now find the total liters of oil in both containers
∴ A + B = 32 + 64 = 96 liters
* There are 96 liters of oil in both containers originally

300 children are divided into 2 groups. There are 50 more children in the first group than in the 2nd group. How many children are there in the 2nd group?
Hei there!
Let's start by letting x be the number of children in the 2nd group. So we can make an equation:
(50+x)+x=300
Next, open parenthesis and combine like terms. Then solve for x.
50+x+x=300
2x=300-50
2x=250
x=125
So, there are 125 kinds in the 2nd group.
Hope I helped, sorry if I'm wrong ouo.

Answer: 125 children
We have an unknown amount of children in the second group, so let us call this x. The number of children in the first class must be x + 50. In other words, the total number of children in both classes would be x + x + 50, which equals to 2x+50, and you have a total of 300 children. Let us start with this equation:
2x + 50 = 300
Subtract 50 from both sides
2x + 50 - 50 = 300 - 50
Simplify
2x = 250
Divide both sides by 2
2x / 2 = 250 / 2
Simplify
x = 125
Again, we said, x is an unknown amount of children in the second group. As you can see, x = 125, so there are 125 children in the second group.
125 + 50 = 175
Since, there are 50 more children in the first group, you would add 50 to 125, and that will give us a total of 175 children in the first group.

____________________________________________________
Answer:
Your answer would be D). Since -2 is to the left of 1, -2 < 1.
____________________________________________________
Step-by-step explanation:
The reason why this would be the correct answer is because it numerically makes sense, and the statement said in the answer choice is correct on the number line.
The numbers that are on the left side of the number line, the negatives, are a lower value than the numbers on the right. To sum it up, the numbers that are more to the left are less value than the ones more to the right.
In the answer choice D, it says, "Since -2 is to the left of 1, -2 < 1."
This is correct because -2 is less than 1, so when you use the the less than sign, it makes sense since -2 is less than 1. To sum it uyp, 1 is greater than -2.
D should be your FINAL answer.
____________________________________________________
Why the other answer choices are incorrect:
The reason why answer choice "A" is incorrect because:
-2 is actually not greater than -1. Remember, The numbers that are more to the right are greater than the numbers on the left. -2 is to the left of -1, which means that -1 would be greater than -2. This statement would be incorrect. This is the reason why this answer choice would be wrong.
The reason why answer choice "B" is incorrect because:
-1 is not equal to 1. -1 is more to the left than 1, and since the negative sign is there, they wouldn't be the same. Even though they have the same number, they don't have the same value. If the equation said 1 =1, it would be true, but that's not the case in this answer choice, which would make it incorrect. This is the reason why this answer choice would be wrong.
The reason why answer choice "C" is incorrect because:
-2 is not greater than 1/3. -2 is negative, while 1/3 is positive, therefore making the 1/3 greater than -2. In the answer choice, it's saying that -2 is greater than positive 1/3, which is incorrect. This is the reason why this answer choice would be wrong.

Find the missing value so that the two points have a slope of -2 (1,y)and (6,-5)
Final answer:
To find the missing value so that the two given points have a slope of -2, substitute the values into the slope formula and solve for y. The missing value is y = 5.
Explanation:
To find the missing value for the given points (1, y) and (6, -5) so that the two points have a slope of -2, we can use the formula for finding the slope between two points:
Slope = (y₂ - y₁) / (x₂ - x₁)
Substituting the given values into the formula, we have:
(-5 - y) / (6 - 1) = -2
Simplifying this equation:
-5 - y = -2(6 - 1)
-5 - y = -2(5)
-5 - y = -10
Solving for y:
y = -5 + 10
y = 5
Therefore, the missing value 'y' is 5.

A. slope = 4/5' and y-intercept = '-(9)/(5)
B. slope = `-(4)/(5) and y-intercept = (9)/(5)
Oc. slope = *-(4)/(5) and y-intercept = *-(9)/(5)
D. slope = °(4)/(5) and y-intercept = "9/59
Answer:

Which conic section is represented by the polar equation r=3/(4+2sintheta)?
A. ellipse
B. hyperbola
C. parabola
D. circle
Answer:
The conic is an ellipse ⇒ answer A
Step-by-step explanation:
* Lets explain how to solve the problem
- The polar form equation of a conic with a focus at the origin, the
directrix is y = ± p where p is a positive real number, and the
eccentricity is a positive real number e is r = ep/(1 ± e sin Ф)
# If 0 ≤ e <1, then the conic is an ellipse
# If e = 1, then the conic is a parabola
# If e > 1, then the conic is an hyperbola
- Lets solve the problem
∵ The equation of the conic is r = 3/(4 + 2 sin Ф)
∵ The form of the equation is r = ep/(1 ± e sin Ф)
- We must divide up and down by 4 to make the 1st term of the
denominator equal 1
∴ r = (3/4)/(1 + (2/4) sin Ф)
∴ ep = 3/4
∴ e = 2/4
- Lets use the rules above to identify the type of the conic
∵ e = 2/4 = 1/2
∴ 0 ≤ e < 1
∴ The conic is an ellipse
Answer:
A C D are the answers
