180
Answer:
30 + 2x = 180
Step-by-step explanation:
This is becuase we know this triangle is an isosceles triangle. (The two markings on the sides prove that.) An isosceles triangle is when two sides (so naturally also two angles) are the same. This means the other angle is x. We know that if we add all of the angles, we'll get 180. So, 30 + x + x = 180 or "30 + 2x = 180".
Also, x = 75.
Here:
30 + 2x = 180
30 - 30 + 2x = 180 - 30
2x = 150
2x / 2 = 150 / 2
x = 75

What is the percentage difference?Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.
Percentage difference= [ (amount made this year / amount made last year) - 1 ] x 100
'(650,000 / 500,000) - 1] x 100 = 30%

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills account earns compound interest. After 25 years, who will earn more interest and how much more will he earn.
Answers
Answer:
Bill will earn more interest
He will earn $ 20,448.67 from his investment
Step-by-step explanation:
Firstly let us calculate Jim's earnings based on simple interest
A = P(1 + rt)
Calculation:
First, converting R percent to r
a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 15000(1 + (0.035 × 25)) = 28125
A = $28,125.00
The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim
Now let's us calculate bill's investment based on compound interest
Equation
A = P(1 + r)^t
A=15000(1+0.035)^25
A=15000(1.035)^25
A=15000*2.36324498427
A = $ 35,448.67
We see that Bill will earn
$ 20,448.67 from his investment
what is the value of x in the equation 3(2x + 8) =0
Answers
Answer:
x=-4
Step-by-step explanation:
1. Distribute
3(2x+8)=0
6x+24=0
2. Subtract 24 from both sides.
6x+24=0
6x+24-24=0-24
3. Simplify
6x=-24
4. Divide both sides of the equation by the same term
6x=-24
[tex]\frac{6x}{6}[/tex] = [tex]\frac{-24}{6}[/tex]
5. Simplify
x=-4
And thats the answer.

11259.5
Step-by-step explanation:
25×386+3219÷2
Multiply 25 and 386 to get 9650.
9650+3219/2
Convert 9650 to fraction 19300/2.
19300/2+3219/2
Since 19300/2 and 3219/2 have the same denominator, add them by adding their numerators.
19300+3219/2
Add 19300 and 3219 to get 22519.
22519/2
Divide 22519 by 2 to get 11259.5.

Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]
[tex]2a + 7a = a(9)[/tex]
Open bracket
[tex]2a + 7a = a*9[/tex]

[tex]5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2[/tex]
Express c as c * c
[tex]c - c^2 = c - c * c[/tex]
Apply distributive property [Factor out c]
[tex]c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r+ r+ r[/tex]
Express r as r * 1
[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]

[tex]r + r + r + r = r(1+1+1+1)[/tex]
[tex]r + r + r + r = r * 4[/tex]

[tex](e)\ 2x - \frac{1}{2}[/tex]
Express 2x as 4x/2
[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]

Independent = cups of milk poured Dependent = Milk left in the gallon jug Independent = Milk left in the gallon jug Dependent = cups of milk poured
Answers
Answer:
Independent = Milk left in the gallon jug
Dependent = cups of milk poured
Step-by-step explanation:
In an experiment or a research, a variable is defined as the thing or a phenomenon that you are trying to found out or measure. Variables can be independent variable as well as the dependent variable.
Independent variable is the variable that the researcher or the experimenter can change or manipulate in the research. This variable does not depend on others and thus stands alone. Its value can be change or altered to find the changes in the dependent variables. They are used as treatment variables.
Whereas, the dependent variables are those variables that are dependent on the values of the independent variables. It is considered as the effect of the independent variable. An independent variable is often manipulated to measure the outcome in the dependent variable.
In the context, the cups of milk poured is the dependent variable and the independent variable is the amount of milk left in the jug.
How would you limit the domain to
make this function one to one?
f(x) = (x + 3)^2
Answers
Answer:
Domain would be x ≥ -3.
So enter -3.
Step-by-step explanation:
This is a parabola with line of symmetry x = -3.
When x has values like say -4 and -2, f(x) will have a value of 1 making the function many to one.
So, to make it one to one, x would have to be equal or greater than -3.
A function assigns values. The limit of the domain to make this function one to one is x≥3.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A one to one function is a function whose every input gives a distinct output. Now given the function is a quadratic function, therefore, the function will have the same output for multiple inputs.
Since the symmetrical axis for this function lies at x=-3, therefore, for the function to be one to one the domain of the function must be greater than or equal to 6.
Hence, the limit of the domain to make this function one to one is x≥3.

Answer:
x = $11
Step-by-step explanation:
5x = $55
9x = $99
2x = $22
In order to find the relationship between x and y, all we have to do is divide y by the term.
$55 ÷ 5 = 11
$99 ÷ 9 = 11
$22 ÷ 2 = 11
Therefore, each ticket sold is $11, or x = $11
Given the function f (x) = x² + 8x + 7, what are the zeros of f?
Answers
Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1
