What percent of 120 is 72?
Show the equation and all work. HELP ASAP
We already have our first value 120 and the second value 72. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
Y = [tex]\frac{72}{120}[/tex]
By multiplying both numerator and denominator by 100 we will get:
Y = [tex]\frac{72}{120}[/tex] × [tex]\frac{100}{100}[/tex] = [tex]\frac{60}{100}[/tex]
Therefore, we get y = 60
You can also find percent of 120 is 72, just by entering 72 ÷ 120 × 100 and you will get your answer which is 60.
Hop you found this helpful!

The sum of the
First n terms of a linear
sequence is
ce is
[tex]2 - 7 {n}^{2} [/tex]
, find the second term
Answer:
-21
Step-by-step explanation:
Given the sum of the first n term as;
Sn = 2 - 7n^2
The nth term is expressed as;
Tn = Sn - Sn-1
Sn-1 = 2 - 7(n-1)^2
Tn = 2 - 7n^2 - (2 - 7(n-1)^2)
Tn = -7n^2 + 7(n-1)^2
To get the second term, we will substitute n = 2 into the resulting expression
T2 = -7(2)^2 + 7(2-1)^2
T2 = -7(4)+7(1)^2
T2 = -28 + 7
T2 = -21
Hence the second term of the sequence is -21

A car is purchased for £11 500 In its first year, the value of the car will depreciate by 15%. Each year after that, the value of the car will depreciate by 10%. What is the value of the car at the end of 3 years?
Answer:
Value of the car at the end of 3 years is £7917.75
Step-by-step explanation:
The car is purchased for £11500.
In the first year, 15% depriciation.
So, depreciation on first year =11500 *[tex]\frac{15}{100}[/tex] =1725
After first year depreciation the value of car =11500-1725 =£9775
Now, second year depreciation is 10%
So, 10% of 9775 =0.10*9775 =977.5
Value of car after 2 years = 9775 -977.5 =8797.5
Now, for third year depreciation is 10%.
So, depreciation on 3 year = 10% *8797.5
=0.10*8797.5
=879.75
So, value of car after 3 years = 8797.5 -879.75 =£7917.75

The range of the given function from the given graph are: all values of y that are greater than or equal to -3. Therefore, the correct option is option D.
What is range of function?It is seen to be best practice to define the word "range" the first time it appears in a book or article because it might have several different meanings. When the word "range" is used in older literature, it frequently refers to what is today known as the codomain.
If more recent texts use the phrase "range" at all, they typically do so to refer to what is now known as the image. Several contemporary novels shouldn't use the term "range" at all to avoid any misunderstandings.
A function's range is the set of each of its potential outputs1,2,3,4. That's the output that the function generates when all of its inputs are used3,5. The range of the given function from the given graph are: all values of y that are greater than or equal to -3.
Therefore, the correct option is option D.

Which of the following functions represents exponential decay and has a y-intercept of 2?
Answer:A
Step-by-step explanation:
The exponential decay functions are y = 2(2/5)ˣ and y = 2(4/3)ˣ
What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
We know,
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
And to find the y-intercept,
Substitute the value of x = 0 and solve for y.
Then y =2.
The functions are y = 2(2/5)ˣ and y = 2(4/3)ˣ
Therefore, the function are y = 2(2/5)ˣ and y = 2(4/3)ˣ.

The area of a bookmark is 140 square centimeters. The perimeter is 54 centimeters. What are the dimensions of the bookmark?
Answer:
See explanation
Step-by-step explanation:
Recall that all the sides of the square are equal
Hence;
Area of a rectangle= l * b ------- equation 1
Perimeter of a rectangle = 2(l + b)----------equation 2
Area of the rectangle = 140 square centimeters
140 = lb
l = 140/b
Perimeter of the rectangle = 54 centimeters
substituting l = 140/b into equation 2
54 = 2(140/b + b)
Multiplying through by b
54b = 280 + 2b^2
Hence;
2b^2 - 54b + 280 = 0
Solving the quadratic equation
b=20 or b=7
substituting b=20 or b=7 into l = 140/b
l = 140/20 or l = 140/7
l = 7 or 20
THEREFORE;
b=20 cm or b=7 cm
l = 7cm or 20cm

Answer:

Step-by-step explanation:
(0,-4) (-4, -3)
-3- -4 / -4 -0 = 1/-4 is the slope
so is C
Answer:
The answer is B.
Step-by-step explanation:
slope-intercept form is y=mx + b with m being slope and b being y-intercept. slope is change in y over change in x, and in this situation the change in y is 1 and the change in x is 4. so, slope = 1/4. so now our equation is y=1/4x+b. now we have to find the y-intercept, which in this graph is -4. so, the equation is y=1/4x+-4.

-11y = 6(2+1) - 13y
4y - 24 = c(z – 1)
For what value of c does the above system of linear equations in the variables y and z have
infinitely many solutions?
Answer:
12
Step-by-step explanation:
Let's put the equations in standard form. For the first equation, we have:
−11y=6(z+1)-13y
2y−6z=6
y−3z=3
The second equation is:
4y−24=c(z−1)
4y−cz=24−c
If we multiply the first equation by 4, we get:
4y-12z=12
Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.
The correct value of c is 12.
