The city's engineer noticed that the bridge is not opening and closing at the same rate and wanted to determine the
rate of change over these intervals. Complete the table to determine the rate of change or the drawbridge (in feet per
minute) at each of the specified intervals.

Find the area of each sector.
Answer:
d. 250π/3
Step-by-step explanation:
A = πr²
A = 3.14(10)² = 314.159
A = 314.159*(5/6) = 261.799
A = 261.799 = 250π/3
Answer:
D
Step-by-step explanation:
You need to set up a ratio between the area of the sector & the area of the circle vs the angle of the sector & 360 degrees.
[tex]\frac{SectorAngle}{360} =\frac{SectorArea}{CircleArea}[/tex]
That above is your formula you need to remember for these equations.
Now let's solve. You've been given the sector angle, which is 300 degrees, and you've been given the radius of the circle, 10 feet.
The area of a circle is the formula: A = πr²
Given that formula and you know the radius. You plug in 10 feet for r and solve for the area.
[tex]A=\pi10^2\\A=314.159[/tex]
Now lets solve for the missing variable (Sector Area).
[tex]\frac{300}{360} = \frac{x}{100\pi }\\100\pi * \frac{300}{360} = \frac{x}{314.159}*100\pi\\100\pi* \frac{300}{360} = x\\\frac{250\pi }{3} = x[/tex]
I kind of messed up since I didn't realize the answer choices were simplified, make sure for the area you don't completely solve the area, keep the pi simple if the answer choices include pi.

SLOPE:
Y-INTERCEPT:
Answer:
slope: 0
y-intercept:(0,49)
Step-by-step explanation:
Hope this helps!
Answer:
SLOPE: 0
Y -INTERCEPT: 49
Step-by-step explanation:
y = -32 - 17 (collect like terms)
y = 49
The slope would be zero because it doesn't have an x-intercept.
The line would look like this..
49 -------------------------------------------- completely flat like the floor so zero slope.

Ok to start of lets identify the money in each bank account
I will not be using names to make this simpler.
Student A: $-100.54
Student B: $95.88
Student C: $50.00
Student D: $-120.37
Lets pretend that were not talking about money to help you understand this.
So just from glancing at this you'd think -120.37 would be the most because its the largest number correct?
Well you have to include the negative sign. The negative sign shows that this number is below 0.
Lets take a look at the other negative number.
-100.54
Greater or less than -120.37?
-100.54 is actually greater than -120.37
Why?
On a number line, the negative side, your counting back from 0. So the farther away you are from 0 for negatives, the less that number is.
So -120.37 would be the least and -100.54 would be the second least.
The greatest would be 95.88 because its greater than 50.
So the order would be 95.88, 50, -100.54, then -120.37
Just find which students that goes with and your done!

You start hiking at an elevation that is 80 meters below base camp.
You increase your elevation by 42 meters. What is the new elevation
with respect to base camp?
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since a negative value is below the base camp, this means that you are now 38 m below base camp.

Answer:
x = −1
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
Original Equation:
15 + 4x = 12 + x
Subtract x from both sides
15 + 3x = 12
Subtract 15 from both sides
3x = -3
Divide both sides by 3
x = -1

Denise bought 116 ounces of beans for a bean dip. She bought both 15-ounce cans and 28-ounce cans, and the total number of cans she bought was 6. Which of these systems of equations can be used to determine the number of 15-ounce cans and the number of 28-ounce cans that she bought? Assume x represents the number of 15-ounce cans and y represents the number of 28-ounce cans.
x + y = 6. 15 x + 28 y = 116.
x + y = 6. 28 x + 15 y = 116.
x + y = 116. 15 x + 28 y = 6.
x + y = 116. 28 x + 15 y = 6.
Mark this and return

15x + 28y = 116
x + y = 6

Write a function for the geometric sequence where the first term is 11 and the common ratio is 4. please help This is due today and I don't understand it I will give brainliest
Given:
In a geometric sequence,
First term = 11
Common ratio = 4
To find:
The function for the geometric sequence.
Solution:
We have,
First term: a = 11
Common ratio: r = 4
We know that, nth term of a geometric sequence is
[tex]a_n=ar^{n-1}[/tex]
Putting a=11 and r=4, we get
[tex]a_n=(11)(4)^{n-1}[/tex]
The function notation is
[tex]f(n)=(11)(4)^{n-1}[/tex]
Therefore, the function for the geometric sequence is [tex]f(n)=(11)(4)^{n-1}[/tex], where n is a positive integer.

At the gas station, each liter of gas costs \$3$3dollar sign, 3, but there's a promotion that for every beverage you purchase you save \$0.20$0.20dollar sign, 0, point, 20 on gas.
Is your total savings on gas proportional to the number of beverages you purchase?
Yes Or No
Answer:
Yes, your total savings on gas is proportional to the number of beverages you purchase.
Step-by-step explanation:
What is a proportional relationship?
A proportional relationship, also known as direct relation, between two variables exists when the ratio between every pair of data is constant.
In this case the variables are:
number of beverage purchased
savings
Thus, as per every beverage purchase you save $ 0.20 the ratio of total savings to the number of beverage purchases is:
savings / beverages purchase = $ 0.20 / beverage
That means that you can determine the savings by multipliying the number of beverages times $ 0.20.
For proportional relationships it is easy to build a table that shows the behavior of the variables. This shows you that:
Number of beverages savings ratio
1 $ 0.20 $0.20 / 1 beverage = 0.20
2 $ 0.40 $0.40 / 2 beverages = 0.20
3 $ 0.60 $0.60 / 3 beverages = 0.20
4 $ 0.80 $0.80 / 4 beverages = 0.20

which of the following is the slope intercept form of the equation of this line
Answer:
The slope-intercept form of the equation of this line is:
[tex]y=-x[/tex]
Hence, option 'c' is true.
Step-by-step explanation:
From the line equation, let us take two points
(1, -1)(-1, 1)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-1,\:1\right)[/tex]
[tex]m=\frac{1-\left(-1\right)}{-1-1}[/tex]
[tex]m=-1[/tex]
From the line graph, we can determine the y-intercept by setting x=0 and checking the y-value at x=0
at x=0, y=0
Thus, (0, 0) is the y-intercept
We know that the slope-intercept form of the line equation is
y=mx+b
where
m=slope b=y-interceptAs we have already determined m=-1 and y-intercept=b=0
so substituting m=-1, b=0 in the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
[tex]y=(-1)x+0[/tex]
[tex]y=-x[/tex]
Thus, the slope-intercept form of the equation of this line is:
[tex]y=-x[/tex]
Hence, option 'c' is true.
Solve the system of equations by substitution.
X + y = 21
y = 6x
Answer:
x = 3
y = 18
Step-by-step explanation:
you replace y with 6x
x + 6x = 21
combine like terms
7x = 21
divide both sides by seven
x = 3
then you plyg 3 into the other equation
y = 6(3)
y= 18
Answer:
x=3
y=18
Step-by-step explanation:
x+y=21..........equation 1
or,x=21-y......equation 2
y=6x.......equation3
substituting the value of x in equation 3
y=6(21-y)
or,y=126-6y
or,7y=126
y=18
again,substituting the value of y in equation 2
x=21-y
or,x=21-18
x=3
x=3,y=18

2X+20 and X+60 I have to solve for X
Answer:
x = 40
Step-by-step explanation:
I don't understand, but I think you mean 2x + 20 = x + 60
So that's what I'm going to solve for if that's wrong tell me what you mean.
2x + 20 = x + 60 (subtract 20 on both sides)
2x = x + 40 (subtract x on both sides)
x = 40
