Answer:
The answer is below
Step-by-step explanation:
Let us assume the relationship between the worker hours and the towers is a linear relationship. A linear relationship is in the form of y = mx + b, where m is the rate of change and b is the value of y when x = 0.
Let y represent the number of worker hours and x represent the number of additional towers. The rate per tower is 0.8 for additional towers. The relationship can be given as:
y = 5500 - 0.8x
a) The number of hours is reduced to 3,000 worker-hours. y = 3000
3000 = 5500 - 0.8x
0.8x = 2500
x = 3125 towers
b) For an additional 16th tower:
y = 5500 - 0.8(16)
y = 5487.2 hours

Determine whether the events are independent or dependent. Explain your reasoning. Returning a rented movie after the due date and receiving a late fee
Answer:
They are dependent
Step-by-step explanation:
A dependent event is one in which its chances of happenning greatly relies on another event. An independent event which is the opposite is one in which its chances of happening is unaffected by another event. In the event described in the question above returning the rented movie after the due date would result in receiving a late fee.
One of the events- receiving a late fee, depends on when the rented movie is returned. This means that the events are dependent.
What the volume of the figure
Answer:
1,530
Step-by-step explanation:
box 1 (left one): 10*9*9=810
box 2 (right one): 18*4*10=720
720+810=1,530
Answer:
1530 cm^3
Step-by-step explanation:
They are two Rectangular Prism.
prism 1.
length l = 18 cm
width w = 10 cm
height h = 4 cm
diagonal d = 20.976177 cm
total surface area S_tot = 584 cm^2
lateral surface area S_lat = 224 cm^2
top surface area St_op = 180 cm2
bottom surface area S_bot = 180 cm^2
volume V = 720 cm^3
Prism 2.
length l = 10 cm
width w = 9 cm
height h = 9 cm
diagonal d = 16.1864141 cm
total surface area S_tot = 522 cm^2
lateral surface area S_lat = 342 cm^2
top surface area Stop = 90 cm^2
bottom surface area Sbot = 90 cm^2
volume V = 810 cm^3
Add 720 cm^3+810 cm^3 = 1530 cm^3
Agenda: l = length
w = width
h = height
d = diagonal
S_tot = total surface area
S_lat = lateral surface area
S_top = top surface area
S_bot = bottom surface area
V = volume
Formula: Volume of Rectangular Prism: V = lwh

how many times does 255 go into 375
Answer: 1 time
255 times 1 is 255. 255 plus 255 is 505. So only goes into 375 once.
Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 7 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Enter the exact answer.
Hint: The distance formula is that distance = rate * time, so for example in one and a half hours, Ben has walked 3 * 1.5 miles.
Answer:
Step-by-step explanation:
Distance = speed * time
For Ben:
speed = 3mi/hr
Time = (x+1.5)hr
Distance = 3 * (x+1.5)
Distance = 3(x+1.5)
For Amanda:
Speed = 7mi/hr
time = 1x
Distance = 7x
Since they cover the same distance then:
3(x+1.5) = 7x
3x + 4.5= 7x
3x-7x = -4.5
-4x =-4.5
x = 4.5/4
x = 1.125 hr
The time taken by Amanda is 1.125 hr

Answer:
70.68 inch is the volume of the rectangular prism
Step-by-step explanation:
V = w × h × l
V = 3.8 inch × 3 inch × 6.2 inch
V = 70.68 inch is the volume of the rectangular prism
To check:
70.68 ÷ 3.8 ÷ 6.2 = 3 inch (height)
70.68 ÷ 6.2 ÷ 3 = 3.8 inch (width)
70.68 ÷ 3.8 ÷ 3 = 6.2 inch (length)
If x = -7, which number line shows the value of |x|?
I NEED ANSWER ASAP YOU WILL GET 50 POINTS
Answer:
A

Because |x| would be absolute value.
Absolute value is always positive so If you had
|-7| it would equal 7.
The number line in option A is the only one that shows it.
Answer: option A
Step-by-step explanation:
Remember, the number line that is option A has absolute value.
So, it would mean this number line is the answer.

The sales price for a jacket is $30. It is 75% off. What is
the original price?
Answer:
$120
Step-by-step explanation:
$120-75% is $30. 1/4 of $120 is $30, so 3/4 is $90. $120-$90 is $30. To find the answer to future equations like this, just multiply the sales price by 4 if the percentage is 75.
It is not $52.50, because 75% of that is $39.375, making that one's sales price 13.125.
Answer:
$52.50 is the original price
Step-by-step explanation:
In order to find the answer, multiply $30 * 0.75 which equals $22.50 and add $30 + $22.50 which would equal $52.50

Answer:
x=20
Step-by-step explanation:
Complementary = 2 angles which = 90 degrees
so 2x+10 + x+20 =90
combine like terms
3x+30=90
-30 -30
3x=60
x=20
lets check! (2(20)+10) + (20+20)
50 + 40 =90 degrees
Answer:
x = 20
angle 1 = 50
angle 2 = 40
Step-by-step explanation:
complementary angles add up to 90
so, you can make this equation:
2x + 10 + x + 20 = 90
combine like terms
2x + x + 10 + 20 = 90
3x + 30 = 90
subtract 30 from both sides of the equation
3x + 30 - 30= 90 - 30
3x = 90 - 30
3x = 60
divide both sides of the equation by 3
3x/3 = 60/3
x = 60/3
x = 20
now, plug x into the angles:
2x + 10
2 * 20 + 10
40 + 10
the first angle is 50°
x + 20
20 + 20
the second angle is 40

A manufacturing process has a 70% yield, meaning that 70% of the products are acceptable and 30% are defective. If three of the products are randomly selected, one after the other, find the probability that all of them are acceptable. Consider these as independent.
Answer:
[tex]Probability = 34.3\%[/tex]
Step-by-step explanation:
Given
Represent acceptable with A and defective with D
[tex]A = 70\%[/tex]
[tex]B = 30\%[/tex]
Required
Determine the probability that three selected are acceptable
This can be represented as:
[tex]Probability = AAA[/tex]
Substitute values for A
[tex]Probability = 70\% * 70\% * 70\%[/tex]
[tex]Probability = 34.3\%[/tex]

A 16-ounce bottle of orange juice says it contains 200 milligrams of vitamin C,
which is 250% of the daily recommended allowance of vitamin C for adults. What is
100% of the daily recommended allowance of vitamin C for adults?
Answer:
Step-by-step explanation:
Use the given functions to set up and simplify
C.A⋅16−ounce=16A−ounce200mil.ligrams=−200m2l2grasC=−200m2l2grams
250%=2.5C=2.5100%=1C=1
Answer:
80 milligrams
Step-by-step explanation:
The volume of bottle is 16-ounce, and the amount of vitamin C in the bottle is 200 mg.
Since the 16-ounce bottle of orange juice says it contains 200 milligrams of vitamin C, which is 250% of the daily recommended allowance of vitamin C for adults. Then for 100% of the daily alowence, we need to multiply 200/250 by 10. We get 80. The picture shows a dubble number line for paper homework. Good luck!

Answer:
Domain: [-4,4]
Step-by-step explanation:
Domain is representative of the space on the graph that x occupies. Because all the points are closed, there should be closed or inclusive brackets outside of the domain. Because the lowest inclusive point is -4, that should be the first domain point. The graph continues until -2, where that line stops, but the second line begins at -2, so we include this point too, and there is no need to mention it in the domain. The second line ends at 4, so that is the highest end of the domain and would be the second domain point. Therefore the domain is [-4, 4]. Remember to keep closed brackets because of the closed points.
