The staff takes 1/2 of an hour to assemble 1/8 of the booths. How long does it take the staff to assemble all of the booths?
Answer:
It takes all staff 3 hours
Step-by-step explanation:
So, first we write down all these important info. It takes half hour for staff to assemble one sixth (1/6) of the booths. First you need to take the fraction 1/6 a whole number by multiplying it by the denominator which in this case is 6 which will give you the answer 1. Next, you do the exact same thing for the other part. Multiply 1/2 by 6 to get 3.
The time to assemble the remaining fraction of the bottle is 3.5 hours.
Time to assemble one-eight of the bottles
The time taken for the staff to assemble one - eight (1/8) of the bottles is given as half (1/2) hour.
Remaining fractionThe remaining fraction of the bottle is calculated as follows;
[tex]= 1 - \frac{1}{8} \\\\= \frac{7}{8}[/tex]
Time to assemble the remaining fraction of the bottlesThe time to assemble the remaining fraction of the bottle is calculated as follows;
1/8 ----------------- 1/2 hour
7/8 ---------------- ?
[tex]\frac{7}{8} \times \frac{1}{2} \times \frac{8}{1} = 3.5 \ hours[/tex]

There is $500 in Holly's bank account. She takes out $50 from her account each month but doesn't put money back in. What is the slope/rate? *
Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptGiven that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
EXTRA BONUS!
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form
[tex]y = mx+b[/tex]
y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500
If point A(-8, 5) is reflected over the line y=2 and then translated according to the rule (x,y) -> (x-1, y-4), what quadrant will point A be in?
9514 1404 393
Answer:
3rd quadrant
Step-by-step explanation:
The second-quadrant point will lie in the 3rd quadrant after reflection over the line. Its coordinates there will be ...
A'(-8, 2·2 -5) = A'(-8, -1)
Then, translation down and to the left will move it further into the 3rd quadrant, to ...
A''(-8-1, -1-4) = A''(-9, -5) . . . . a 3rd-quadrant point

Answer:
x= 10
Step-by-step explanation:
8x+30=110
8x+30-30=110-30
8x=80
8x/8=80/8
x=10
Answer:
x=10
Step-by-step explanation:
Vertical angles are always congruent, those to angles are vertical angles so they are congruent.
Set them equal to each other:
110=8x+30 subtract 30 from both sides
80=8x divide by 8 on both sides
x=10

Write the equation of a line that is parallel to y=x-4 and passes through the point (2,3)
Answer:
y = x - 1
Step-by-step explanation:
The given line is y = x - 4. Any line parallel to this one has an equation of the same form, though the constant will be different.
Substitute the coordinates of the given point (2, 3) into y = x - 4 and determine the value of b, which is the y-intercept:
3 = 2 - C
Then C = -1, and the desired equation is y = x - 1.
3x+2y=46 x+y=17 how u solve
Answer: (12, 5)
Step-by-step explanation:
3x + 2y = 46 x + y = 17
Subtract y from both sides of the equation.
x = 17 − y 3x + 2y = 46
Replace all occurrences of x with 17 − y in each equation.
51 − y = 46
x = 17 − y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
Subtract 51 from both sides of the equation.
−y = 46 − 51
x = 17 − y
Subtract 51 from 46.
−y = −5
x = 17 − y
Multiply each term in −y = −5 by −1
Multiply each term in −y = −5 by −1. (−y) ⋅ −1 = (−5) ⋅ −1
x = 17 − y
Multiply (−y) ⋅ −1.
y = (−5) ⋅ −1
x = 17 − y
Multiply −5 by −1.
y = 5
x = 17 − y
Replace all occurrences of y with 5 in each equation.
Replace all occurrences of y in x = 17 − y with 5. x = 17 − (5)
y = 5
Simplify 17 − (5).
Multiply −1 by 5.
x = 17 − 5
y = 5
Subtract 5 from 17.
x = 12
y = 5
The solution to the system is the complete set of ordered pairs that are valid solutions.
(12, 5)
The result can be shown in multiple forms.
Point Form: (12, 5)

The number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees. Which expression represents how many trees will be left in 10 years. Group of answer choices
Answer:
[tex]y=2.5*10^9(0.005^{12 0}) \\\\[/tex]
Step-by-step explanation:
The above question is in the form of an exponential decay. The equation for an exponential decay is given by:
[tex]y=ab^x[/tex]
where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).
Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:
[tex]y=2.5*10^9(0.005^x)\\\\After\ ten\ years(x=10*12\ months=120\ months):\\\\y=2.5*10^9(0.005^{12 0}) \\\\[/tex]
Sammy earns money for college by walking dogs and mowing lawns. She earns $3 for each dog she walks and $25 for each lawn she mows. Which expression can be used to determine the amount of money she earns from walking w dogs and mowing m lawns
Answer:
x = 3w + 25m
Step-by-step explanation:
The number of dogs she walks (w) and the number of lawns that Sammy mows (m) need to be multiplied by the amount of money that Sammy makes from each individual action. Both of these products are then added together to equal the total amount of money that Sammy has earned. All of this can be represented with the following expression where x is the total amount of money earned...
x = 3w + 25m

Answer:
C
Step-by-step explanation:
Firstly, we will identify the angle that has the given cosine value
From what we can see, the arc cos of this value is 45 degrees
but, as we can see, the value is negative
On the quadrants, the value of cosine is negative on the 2nd and 3rd quadrant
2nd quadrant ranges from 90 - 180
That is pi/2 to pi
3rd ranges from 180 to 270
That is pi to 3pi/2
Kindly recall, we are considering angles from -360 to 360
So what this mean is that we will consider angles that are negative of what we have as positive angles on the first and fourth quadrant on which cosine is positive
Thus, we have the following;
5pi/4 is same as 225 degrees
This is on the 3rd quadrant, and cosine is negative there
7pi/4 is same as 315 and this is on the fourth quadrant
This is expected to be negative because normally, cosine is positive on that axis and what we have should be negative
3pi/4 is same as 135
This is on the second quadrant and normally, cosine is negative here so we do not need to negate the angle measure
pi/4 is on the first quadrant and cosine is positive here;
Since the value we have here is positive, we have to negate the angle measure
So the correct angles are;
negative pi/4
positive 3pi/4
positive 5pi/4
negative 7pi/4
