The area of the rectangular sheet is 500cm square. If the length of the sheet is 25cm, what is its width? Also find the perimeter of the rectangular sheet.
Answer:
20cm Perimeter: 90
Step-by-step explanation:
Hope this helps!(^-^)
Step-by-step explanation:
area of rectangular sheet is 500 CM square
length =25cm
area =l×b
500cm2=25cm×b
500cm2÷25cm=b
20cm=b
b=20cm
again,
perimeter =2(l+b)
perimeter =2(25cm+20)
perimeter =2×45
perimeter =90cm

Is the relation shown in the table below a function? Explain.
Answer
No
Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function
No, the given relation is not a function. A function is a connection between inputs in which each input is connected to precisely one output.
What is a function?A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, co-domain, and domain for every function.
Given, a table where points are denoted as inputs and outputs.
To prove the relation is a function:
A relation between a collection of inputs and outputs is known as a function.
A function is a connection between inputs in which each input is connected to precisely one output.
But here, input value of 3 have two outputs.
Which gives us contradiction.
Therefore, a given relation is not a function.

Answer:
20Step-by-step explanation:
The equation of shifted function y = ax² is y = a(x-h)²+k, where h tells us how many units we move left (h<0) or right (h>0) and k tells how many units up (k>0) or down (k<0)
y = x² - 20 = 1(x - 0)² + (-20) ⇒ k = -20<0
So it's shifted 20 units down.
What expression is equivalent to (-18) - 64n
-18-64n
= (-2)×9 + (-2)×32n
Take (-2) common, we get
= (-2)( 9+32n)
Therefore,
-18-64n = (-2)(9+32n)

A product is marked down 15%; the sale price is $127.46. What
was the original price?
Answer: $ 149.95.
Step-by-step explanation:A product is marked down 15%; the sale price is $127.46. What was the original price? Substitute 127.46 for S.P and 15 for m in (1). So, the original price is $ 149.95.
The original price of the product will be $149.95.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred.
A product is marked down 15%.
The sale price is $127.46.
Then the original price of the product will be
Let x be the original price.
(1 – 0.15)x = $127.46
0.85x = $127.46
x = $149.95

Answer: A.
Step-by-step explanation: The fashion express magazine having 4,880 subscribers and losing 300 times something lines up with that in the expression. And the new trends magazine having 3,140 and gaining 280 times something lines up with the expression. The expression is also suppose to be equal and the word problem is asking for when the subscriber count would be equal. Solving the expression using the word problem would have you end up with m = 3, so in 3 months they will have equal subscribers (aka both will have 3,980 subscribers)

Question 1
You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=-11x+330, where x is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercepts of the graph.
Answer:
Domain
[tex]x\in [0\,s,30\,s][/tex]
Range
[tex]h \in [0\,ft,330\,ft][/tex]
The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.
The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.
The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.
Step-by-step explanation:
Both the time (domain), measured in seconds, and the height (range), measured in feet, are positive variables. The hot air balloon start at a height above and descends to the ground. Which means that domain and range of the function are, respectively:
Now we find the upper bound of the height of the hot air balloon. If we know that [tex]t = 0\,s[/tex], then the upper bound is:
[tex]h(0) = -11\cdot (0)+330[/tex]
[tex]h(0) = 330\,ft[/tex]
Range
[tex]h \in [0\,ft,330\,ft][/tex]
Now we find the upper bound of time. If we know that [tex]h = 0\,ft[/tex]. then the upper bound is:
[tex]-11\cdot x +330 = 0[/tex]
[tex]11\cdot x = 330[/tex]
[tex]x = 30\,s[/tex]
Domain
[tex]x\in [0\,s,30\,s][/tex]
The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.
The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.
The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.

Find the 15th term or the geometric sequence 7, -21, 63,
33480783
Step-by-step explanation:Finding the Common Ratio:
We know that the formula for the common ratio of a GP is:
r = aₙ / (aₙ₋₁) (Where n is any integer)
replacing the values, taking n=2
r = -21 / 7
r = -3
Solving for the 15th Term:
We know that the Formula for the nth term of a GP:
G(n) = a * r ⁿ⁻¹ (where a is the first term and r is the common ratio)
replacing the values (taking n = 15 since we need the 15th term)
G(15) = 7 * (-3)¹⁴
G(15) = 33480783
Hence, the 15th term of the given GP is 33480783

Answer:
there are 114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)

Lila and Nina are at college and spending their savings. Nina has $1,500 and is spending $80 a week. Lila has $600 and is spending $20 a week. Write and solve an equation that will figure out how long it will take for them to have the same amount of money.
So you can take this as a sequence. For Nina the term would be 1,500 and second be 1,420. So the equation for it would be -80n + 1580. For Lila it would be -20n + 620. 1,500 and 600ths highest common factor is 300. So it would take Nina 16 weeks. For Lila it would take 16 as well.

Question 1 (1 point)
A mail carrier divides 4,830 envelopes into boxes. Each box can hold a maximum of 50 envelopes.
What is the minimum number of boxes the mail carrier must use?
Answer:
97 boxes
Explanation:
4,830÷50= 96.6
You then have to round 96.6 up and you get 97.
To check your answer:
97×50= 4,850
Even though having 97 boxes leaves more room for envelopes, having 96 boxes will leave all the boxes full with remaining envelopes. 96 boxes isn't enough for 4,830 envelopes.
