Step-by-step explanation:
When given a question like this, you have to separate the variables by adding the one with the same variable together. If you add 5x and -8x you will get -3x and if you add 7w with -7w, you'll get 0w which isn't needed in the equation. 20xw would be alone.

On a Ferris wheel, Sarah observes that it takes 45 seconds for her chair to complete a full revolution. Her chair is 30 feet from the axle of the Ferris wheel.
To the nearest hundredth, Sarah’s angular velocity is ____ radians per minute
Answer:
8.38 radians
Step-by-step explanation:
correct on edge 2021
The angular velocity of the Ferris wheel is 8.38 radians/minute.
What is angular velocity?"The angular velocity is the time rate at which an object rotates or revolves about an axis."
It takes 45 seconds for her chair to complete a full revolution.
Therefore, in terms of revolution per minute, the speed is
= 60/45 revolutions/minute
= 4/3 revolutions/minute.
We know, 1 revolutions = 2π radian
Therefore, 4/3 revolutions/minute
= (4/3) × 2π radians/minute
= 8.38 radians/minute
Hence, the angular velocity is 8.38 radians/minute.

Mr. Gaines is catering his company picnic. He will pay $18.45 for 3 people to eat the barbecue lunch. At this rate, how many people can Mr. Gaines afford to feed on a budget of $1850.00? (Will give brainliest)
Answer: 300
Step-by-step explanation:
From the question, we are informed that Mr Gaines is catering his company picnic and that he will pay $18.45 for 3 people to eat the barbecue lunch. This means each person spends:
= $18.45/3
= $6.15
With a budget of $1850.00, the number of people that he'll be able to feed will be:
= $1850/$6.15
= $300 people
Tom is 4 more than twice andrews age. Sara is 8 less than 5 times ANdrews age. If tom and sara are twins how old is andrew
Answer:
there
Step-by-step explanation:
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
Heather was assigned the task of making labels for all of the drawers in the file cabinets in her office. There were 12 file cabinets. Three cabinets have 4 drawers; all the other cabinets have 5 drawers. How many labels will Heather need to make?
Answer:
52 Labels
8 cabinets with 5 drawers 8x5=40
3 cabinets with 4 drawers 3x4=12
40+12=52
Answer:
Heather will need to make 57 labels to complete the task.
Step-by-step explanation:
There are 12 file cabinets.
Three of them have 4 drawers.
Heather will need to make 3*4=12 labels for these cabinets
The rest of the cabinets (12-3=9) have 5 drawers.
Heather will need to make 9*5=45 labels for these cabinets
The total of labels needed is 12+45=57.
Heather will need to make 57 labels to complete the task.

find the y-intercept of the graph of 2x-5y=10
Answer:
y-intercept: ( 0 , − 2 )
Step-by-step explanation:
To find the y-intercept, substitute in 0 for x and solve for y
Answer:
(0,-2)
Step-by-step explanation:
Start with:
[tex]2x-5y=10[/tex]
We are going to want this equation in slope-intercept form.
[tex]y=mx+b[/tex]
[tex]mx=slope[/tex]
[tex]b=y-intercept[/tex]
To get the equation in slope intercept from, start by subtracting [tex]2x[/tex] from both sides of the equation:
[tex]-5y=-2x+10[/tex]
Now, divide both sides of the equation by [tex]-5[/tex]:
[tex]y=-\frac{2}{5}x -2[/tex]
[tex]b=-2[/tex]
[tex](0,-2)[/tex]
A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)^x. To the nearest hundredth, how much sodium-24 can the scientist predict will remain 12 hours after the experiment started?
_mg
Answer:
56.43
Step-by-step explanation:
The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)ˣ.
The amount of the sodium-24 that scientists can predict will remain 12 hours after the experiment started will be given as,
y = 98.8 (0.9544)¹²
y = 98.8 (0.571169)
y = 56.43 mg
The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.

after how many seconds is needed for a thrown ball to reach a 14-m distance if it's distance is given by the relation d=10+40t-5t? (t=time in seconds)
Answer:
Time, t = 0.1143 seconds.
Step-by-step explanation:
Given that distance, d = 14m
From the equation;
d = 10 + 40t - 5t
d = 10 + 35t
Substituting the value of distance;
14 = 10 + 35t
35t = 14 - 10
35t = 4
t = 4/35
t = 0.1143 seconds.
The time needed for the ball to reach the 14-m distance is 0.1143 seconds.
The thrown ball will reach a 14-m distance after 0.114 seconds.
The relation given is:
d = 10+40t-5t
where, d = 14
In this case, we've to put the value of d into the relation and this will be:
d = 10+40t-5t
14 = 10 + 40t - 5t
Collect like terms
40t - 5t = 14 - 10
35t = 4
Divide both side by 35
35t/35 = 4/35
t = 0.114 seconds.

Answer:
56cm
Step-by-step explanation:
5488 is the area of the rectangle.
we know that length x width = area
so to find the with we do area/length
so, 5488/98 =56
Answer: 56 cm
Step-by-step explanation:
Area (A) = Length (L) × width (w)
Given: A = 5488 cm², w = 98 cm
A = L × w
5488 = L × 98
56 = L Divided 98 from both sides
