Find the missing angle in the triangle below
Answer:
120
Step-by-step explanation:
Exterior angle theorem
50 + 70 = 120
Answer:
120
Step-by-step explanation:
the insides of a triangle add up to 180 degrees. You're given 70 and 50 degrees which add to 120 and that means the other angle is 60 degrees. Since you're trying to find an outside angle, you need to do subtract the 60 degrees we just found from 180 (because its a supplementary angle). 180-60 is 120 and thats the answer

I hope l helped you. ❤❤if an is a monotone sequence and if an has a convergent subsquence then an converges to the same limit
limₐ→∞xₙₐ= limₙ→∞xₙ= L;
Let xₙ be a monotonically increasing sequence. Thus:
xₙ₊₁≥xₙ
Consider a subsequence of xₙ namely xₙₐ. Then:
xₙₐ≥xₙ, ∀nₐ≥n
We are also given that:
limₐ→∞xₙₐ=L
Given that fact we know that xₙₐ is bounded above. Therefore:
xₙ≤xₙₐ≤L
Now by monotone convergence theorem a monotone bounded sequence must be convergent. Also by uniqueness of a limit for a convergent sequence and the fact that all its subsequences are also convergent to the same limit:
limₐ→∞xₙₐ= limₙ→∞xₙ= L

Find the sale price to the nearest cent
$53 pair of jeans with a 20% discount
Answer: It is $42.4
Step-by-step explanation: Multiply (0.20)(53), you get 10.6, now that's the price that is discounted, so subtract that from the total, to get $42.4. If you want to check your answer, do 42.4/53 and you would get 0.80, or 80%. That is what you should get since you have a 20% discount from 100% of a product.
Answer:
the sales price is $10.60
Step-by-step explanation:
to find 20% of 53, I multiplied 53 by 20 and 100 by a (i used the variable a to substitute for the answer we are going to get)
53 x 20 = 1060
100 x a = 100a
In order to get "a" we have to divide by 100 for each number.
1060 ÷ 100 = 10.6
100a ÷ 100 = a
in conclusion, a = 10.6, or $10.60 hope this helps :)

four consecutive integers sum to 22 what is the least of these integers
Answer:
4
Step-by-step explanation:
To get 22 with four consecutive integers, we need the integers 4, 5, 6, and 7.
(4 and 5 equal 9, then 9 and 6 equal 15, and 15 and 7 equal 22.)
4 is the smallest of these four, and thus the least of these.

Step-by-step explanation:
4. because the graph is in a negative direction and the point is higher than 0

Answer:
The length of the third side of the triangle is 30.
Step-by-step explanation:
Here is the formula for the Pythagorean Theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!
We need to multiply 40 times 40 and 50 times 50.
40 times 40, or 40 squared, equals to 1600.
50 times 50, or 50 squared, equals to 2500.
[tex]c^{2} - b^{2} = a^{2}[/tex]
Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
Answer:
30
Step-by-step explanation:
c=√a^2+b^2
a=√c^2-b^2 = √50^2-40^2 = 30
Dasher was super hungry after his big night so he ordered 4 candy cane pies. He ate 3/5 of the pies on the way home. How much pie did he have left when he got home?
Answer:
He had 3 2/5 pies left when he got home.
Step-by-step explanation:
Hope this helped have an amazing day!
The fraction of candy cane pies that Dasher left is 8/5.
What is a fraction?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, if we divide two numbers by each other then the upper word is called the numerator, and the lower word is called the denominator.
As per the given,
Number of candy cane pies that Dasher order = 4
Fraction he ate = 3/5
Left = 4 - ate
Left = 4 - (3/5)4
Left = 4(1 - 3/5)
Left = 4(2/5)
Left = 8/5
Hence "The fraction of candy cane pies that Dasher left is 8/5".

Barinda is considering running for student government. However, she knows she will have to work about 10 hours fewer per week if elected, and she makes $ 7 an hour. The campaign will also cost her about $100 in campaign buttons and posters. What is her opportunity cost for serving on student government if elected if she actively serves for 30 weeks?
Answer: $2,200
Step-by-step explanation:
The opportunity cost is the sum of the amount she spent on the election and the amount she would lose in total from serving on the student government.
Amount she would lose in wages
= 7 * 10 hours * 30 weeks
= $2,100
Opportunity cost = 2,100 + 100
= $2,200

Mrs smith invested r60 000 at a bank for two years with compound interest.in the first year she received an interest rate of 4,3% per annum while in the second year the interest rate was 5,1 per annum mrs smith stated that she would have enough money at the end of second year to pay the residual value of the ford figo show all calculations whether het statement is correct
By using the formula of compound interest we can say that at the end of second year Mrs. Smith will have $65,771.58.
What is Compound Interest?The interest earned from the initial deposit plus the cumulative interest is known as compound interest.
A = P(1 + r/n)^(nt), where P is the principle balance, r is the interest rate, n is the number of times interest is compounded per time period, and t is the total number of time periods, is the formula for compound interest.
Given that,
For first year,
P (principal) = $60,000.00
R = 4.3%
n = 1
t = 1
First, convert R as a percent to r as a decimal
r = R/100
r = 4.3/100
r = 0.043 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 60,000.00(1 + 0.043/1)^(1×1)
A = 60,000.00(1 + 0.043)^(1)
A = $62,580.00
A = P + I where,
P (principal) = $60,000.00
I (interest) = $2,580.00
So, by the end of second year Mrs. Smith will have $62,580.00.
Now, the amount calculated from first year will become the principle for second year.
For second year,
P (principal) = $62,580.00
R = 5.1%
n=1
t=1
First, convert R as a percent to r as a decimal
r = R/100
r = 5.1/100
r = 0.051 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 62,580.00(1 + 0.051/1)^(1×1)
A = 62,580.00(1 + 0.051)^(1)
A = $65,771.58
A = P + I where,
P (principal) = $62,580.00
I (interest) = $3,191.58
So, by the end of second year Mrs. Smith will have $65,771.58.

function f(x)={2x,x<1 5, x=1
What is the value of x + y + 5 if x = 6 and y = 15?
Answer:
26
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Step 1: Define
x + y + 5
x = 6
y = 15
Step 2: Evaluate
Substitute: 6 + 15 + 5Add: 21 + 5Add: 26find all values of c in the open interval (a, b) such that f'(c)=(f(b)-f(a))/(b-a)
f(x)=4sin(x), [0,π]
There is only one value of c that satisfies the requirements.
=======================================================
Work Shown:
Let's compute the function value at the given endpoints of the interval.
[tex]f(x) = 4\sin(x)\\\\f(\pi) = 4\sin(\pi) = 0\\\\f(0) = 4\sin(0) = 0\\\\[/tex]
Which means,
[tex]f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(\pi)-f(0)}{\pi-0}\\\\f'(c) = \frac{0-0}{\pi}\\\\f'(c) = \frac{0}{\pi}\\\\f'(c) = 0\\\\[/tex]
We want to find all values of c such that the derivative is 0.
This can be rephrased into wanting to solve [tex]4\cos(x) = 0\\\\[/tex] since the derivative of sine is cosine
In other words, [tex]f(x) = 4\sin(x)\\\\[/tex] turns into [tex]f'(x) = 4\cos(x)\\\\[/tex]
Solving that equation leads to:
[tex]4\cos(x) = 0\\\\\cos(x) = 0\\\\x = \frac{\pi}{2}\\\\[/tex]
Use a reference table or the unit circle to determine this.
This is the value of c that satisfies f ' (c) = 0, such that [tex]0 < c < \pi[/tex]. No other value of c works.
If you graphed f(x) = 4sin(x), and only focused on the interval [0,pi], then you'll find that there's a horizontal tangent at the point (pi/2, 4). Note how the endpoints have the same y value so that's why the average rate of change over [0,pi] is 0.
