What is the measure of an angle if it is 120 less
than four times its own supplement?
Answer:
120°
Step-by-step explanation:
x = angle supplement = 180-x
x = 4(180-x) -120
x = 720 - 4x - 120
5x = 600°
x =120°

Teddy opens a new bank account by depositing the $245 he has saved from mowing lawns. He chose
this account because it will accrue 2% monthly and he wants to save up $2,000 for a car within a
couple of years.
P
Answer:
245 +4.9m = 2000
Step-by-step explanation:
so 245 is what he has and he puts it where he gets 2 percent monthly so 4.9 is 2 percent of 245. 2000 is there because that's how much he wants to save.

abc has a $5 million liability at december 31, 2018, of which $1 million is payable in each of the next five years. abc reports the liability on the balance sheet as a:
ABC reports the liability on the balance sheet as a $1 million current liability, and a $4 million long-term liability.
What are current and long-term liabilities?A current liability is a liability that is payable within 12 months or one year.
On the other hand, a long-term liability is a liability that is payable after 12 months or one year.
Since $1 million is payable in each of the next five years, this implies $1 million is payable within one year while $4 million is payable after one year.
Therefore, ABC reports the liability on the balance sheet as a $1 million current liability, and a $4 million long-term liability.

The sum of a number 8 and twice the number X is 28
ANSWERS ARE AT THE BOTTOM
To solve this question, we need to write the questions algebraically. Let's look at the problem first: The sum of a number 8, and twice the number x is equal to 28.
Algebraic form:
8 + 2x = 28
Lets solve this!
8 + 2x = 28 (Algebraic Form)
2x = 28 - 8 (Subtract 8 from both sides)
2x = 20 (Divide by 2)

Repost question: Guys, can you please help me write an expression for shaded area circle and please expand and simplify for me, guys, please? :)
Step-by-step explanation:
area of shaded area = area of larger circle - area of smaller circle
a = pi * (r+7)^2 - pi * r^2
a = pi * r^2 + 14pi*r + 49* pi - pi * r^2
pi r^2 cancels
a = 14*pi*r + 49 *pi
a = 7pi(2r + 7)
Answer:
14πr + 49π
Step-by-step explanation:
Logically, to find the area of the border of a circle, we need to find both the area of the inner circle [not including border] and the area of the outer circle [including border]
Once we have found these two areas, we find the difference (difference meaning subtraction) between the two values.
We know that the area of a circle = πr²
We can use this formula to find the area of both circles.
Inner circle:
πr²
(cannot be simplified further)
Outer circle:
π(r + 7)²
(r + 7)² = (r + 7)(r + 7) = r² + 7r +7r +49 {FOIL method}
outer - inner
π(r² + 14r + 49) - πr²
π (r² +14r +49)= πr² + 14πr + 49π
πr² + 14πr + 49π - πr²
πr² - πr² = 0
So, the area of our border is: 14πr + 49π
hope this helps!!

A bag contains equal numbers of green marbles and blue marbles. You can divide all of the green marbles into groups of 12 and all the blue marbles into groups of 16. Whatis the least number of each color of marble thatcan be in the bag
Answer: 48
Step-by-step explanation:
We need to find the least common multiple of 12 and 16.
Finding the prime factorizations of 12 and 16,
[tex]12=2^{2} \times 3\\\\16=2^{4}[/tex]
Thus, the least common multiple is [tex]2^{4} \times 3=\boxed{48}[/tex]
The vertex of this parabola is at (3-2). When the value is 4 the
y-value is 3. What is the coefficient of the squared expression in the
parabola's equation?
A. 7
B. 1
C. -1
D. 5
Answer:
D
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here (h, k ) = (3, - 2 ) , then
y = a(x - 3)² - 2
to find a substitute the point (4, 3 ) into the equation
3 = a(4 - 3)² - 2 ( add 2 to both sides )
5 = a × 1² = a
the coefficient of the squared expression is 5
By the distributive law 49 x 17 + 49 x 3=
Answer:
49(17 + 3)
Step-by-step explanation:
The Distributive Law says [tex]a(b+c)=ab+ac[/tex]. But it can be used in the other direction, [tex]ab+ac=a(b+c)[/tex]. That way, you look at ab and ac to find the common factor a. What's playing the role of a in the expression 49 x 17 + 49 x 3? It's 49, the factor that shows up twice. That's the factor that can be taken outside the parentheses.
49 x 17 + 49 x 3 = 49(17 + 3)
Solve for x......
[tex]4x + 10 = 2x + 26[/tex]
Answer:
x=8
Step-by-step explanation:
4x+10 = 2x+26
4x-2x+10=2x-2x+26 [Subtract 2x from both sides]
2x+10=26
2x + 10 - 10 = 26 - 10 [Subtract 10 from both sides]
2x = 1
2x/2 = 16/2 [Divide both sides by 2]
x = 8
CHECK:
Does 4x+10 = 2x+26 when x is 8?
4(8)+10 = 2*(8)+26 ?
32+10 = 16+26 ?
42 = 42 YES
Answer:
[tex]\large \boxed{\sf x =8}[/tex]
Explanation:
[tex]\sf \rightarrow 4x + 10 = 2x + 26[/tex]
collect like terms
[tex]\sf \rightarrow 4x -2x = 26-10[/tex]
subtract like terms
[tex]\sf \rightarrow 2x = 16[/tex]
divide both sides by 2
[tex]\sf \rightarrow x = 8[/tex]
If 5 men or 10 women can complete any work in 50 days. Than in how many days 8 men and 4 women complete that whole work?
Firstly, let’s assume the the whole capacity the work requires is 1.
Then, let’s see how 1 man can do in 50 days: 1/5.
Further, let’s see how 1 man can do in 1 day : 1/(5×50) = 1/250.
Similarly, let’s see how 1 woman can do in 1 day: 1/(10×50) = 1/500.
Now, we have 8 men, and they can do 8*1/250 in 1 day, which is 4/125.
Besides, we have 4 women, and they can do 4×1/500 in 1 day, which is 1/125.
Therefore, all people we have can do 4/125 + 1/125 of the work in 1 day, which is 1/25.
As a result, the work takes 1/(1/25)= 25 days.

Step-by-step explanation:
Geometric sequence
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
(where a is the first term and r is the common ratio)
Given:
[tex]\displaystyle \sum^{20}_{n=1} 4 \left(\dfrac{8}{9}\right)^{n-1}[/tex]
Therefore:
a = 4r = 8/9Sum of the first n terms of a geometric series:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
To find the sum of the first 20 terms, substitute the found values of a and r, together with n = 20, into the formula:
[tex]\implies S_{20}=\dfrac{4\left(1-\left(\frac{8}{9}\right)^{20}\right)}{1-\left(\frac{8}{9}\right)}[/tex]
[tex]\implies S_{20}=32.58609013...[/tex]

If f(x) = 2x – 5, find the inverse. This function passes the Horizontal Line Test which means it is a onetoone function that has an inverse. y = 2x – 5 Change f(x) to y. x = 2y – 5 Switch x and y. Solve for y by adding 5 to each side and then dividing each side by 2.
A function assigns the values. The inverse of the function is y = (x+5)/2.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
To find the inverse of the function, the function is needed to be solved for x, and then replace x with y and vice versa. Therefore, the inverse of the function will be,
f(x) = y = 2x - 5
y = 2x - 5
y + 5 = 2x
x = (y+5)/2
y = (x+5)/2
Hence, the inverse of the function is y = (x+5)/2.

Answer:
2y + 3 = 4y + 2; y = 1/2
Step-by-step explanation:
to find this equation we can use the ys and the 1s to create an equation
so
in the left side
there are 2 ys and 3 1s
your equation is
2y + 3
on the other side
it is
4 ys and 2 1s
so
4y + 2 is your equation
then yo uset them equal to each other
2y + 3 = 4y + 2
if you must solve
subtract 2y and 2 from both sides
1 = 2y
then divide both sides by 2
y = 1/2 is your answer
