Find the measure of each angle indicated (quadrilaterals)
I think it’s 100 I just wanna make sure if it is
Find the measure of each angle indicated.
○ 44°
○ 68°
○ 59°
○ 100°
____________________Solution :-Given Information :-∠S = 95° ∠T = 85° ∠Q = 80° To Find :-The measure of ∠R Formula Used :-Sum of all angles of a Quadrilateral = 360° Calculation :-We will simply substitute the given values in the formula,
⇒ Sum of all angles of a Quadrilateral = 360°
⇒ ∠S + ∠T + ∠Q + ∠R = 360°
Substituting the values given, We get,
⇒ 95° + 85° + 80° + ∠R = 360°
Calculating further, We get,
⇒ 260° + ∠R = 360°
Transposing 260° to Right Hand Side, We get,
⇒ ∠R = 360° - 260°
Calculating further, We get,
⇒ ∠R = 100°
∴ ∠R = 100°
____________________Final Answer :-The measure of ∠R is 100°
Hence, Last option i.e., 100° is correct answer.
____________________Find the margin of error for the given values of c, s, and n.
c=0.95, s=2.5, n = 26
Answer:
0.9609
Step-by-step explanation:
Margin of error is expressed using the formula;
M = z * √s²/n
z is the 95% z score = 1.96
s is the standard deviation = 2.5
n is the sample size = 26
M = 1.96 * √2.5²/26
M = 1.96 * √0.2404
M = 1.96 * 0.49029
M = 0.9609
Hence the margin of error is 0.9609

A chemist mixes 25 milliliters of a solution that is 44% acid with 225 milliliters of pure acid.
(a) How many milliliters of acid are in the resulting
mixture?
milliliters
(b) What percentage of the resulting mixture is acid?
Answer: a) 236 ml b) 94.4 %
Step-by-step explanation: a) in 44 % solution there is 0.44 · 25 ml = 11 ml.
Total volume of acid is 225 ml + 11 ml = 236 ml
b) vol-% of acid is 236 ml /(225 ml + 25 ml) · 100 % = 94.4 %
The milliliters of acid that are in the resulting mixture is 236 millimeters and the percentage of the resulting mixture is acid is 94.4%.
a. The milliliters of acid are in the resulting mixture will be:
= 225 ml + (44% × 25ml)
= 225ml + (0.44 × 25ml)
= 225ml + 11ml
= 236ml
b. The percentage of the resulting mixture that is acid will be:
= [(236ml / (25ml + 225ml)] × 100
= (236ml/250ml) × 100
= 94.4%

If my dad is 3x my age today and he was 4x my age 10 years ago, how old will I be in 25 years from now?
Answer:
55
Step-by-step explanation:
We can use the given relations to write an equation that can be solved for my age 25 years from now.
__
Let x represent my age in 25 years. The age relationships can be summarized as ...
in 25 years -- me: xnow -- me: x-25; dad: 3(x-25) = 3x-7510 years ago -- me: x-35; dad: 3x -85We know 10 years ago my dad was 4 times my age, so we have ...
4(x -35) = 3x -85
4x -140 = 3x -85 . . . eliminate parentheses
x = 55 . . . . . . . . . . . add 140-3x
I will be 55 in 25 years from now.

Please anybody help I need to finish this today!!
Answer:
well Liam is right that is the same statement
please help me!!! justify your answers.
Answer:
G is true is out divide 1/7 by 2 out get 1/14
H is false the product is always 1
I is false all numbers have a reciprocal besides 0
Answer:
g. True
h. False
i. False
Step-by-step explanation:
g.
[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]
This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]
If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]
The numerator is 1 * 1 which is 1
And then the denominator is 7 * 2 which is 14
That would give you [tex]\frac{1}{14}[/tex]
h.
The products of two reciprocals is 0
This is not true
Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.
Ex: [tex]\frac{2}{8}[/tex]
Its reciprocal is [tex]\frac{8}{2}[/tex]
So multiply them together
[tex]\frac{2}{8}* \frac{8}{2}[/tex]
2 * 8 = 16
8 * 2 = 16
[tex]\frac{16}{16} = 1[/tex]
i.
A whole number does not have a reciprocal
This is incorrect. If you think about it, a whole number is just the number, over 1
Ex: [tex]\frac{6}{1}[/tex]
This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.
If you an write it as a fraction, it has a reciprocal.
The reciprocal in this case would be [tex]\frac{1}{6}[/tex]

Based on the density graph below, what is the probability of a value in the sample space being anywhere from 10 to 25?
A. 80% B. 60% C. 40% D. 20%
The probability of the sample from 10 to 25 will be 60%. Then the correct option is B.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
Based on the density graph below.
Then the probability of a value in the sample space being anywhere from 10 to 25 will be
P = (25 - 10)/(25 - 0)
P = 15/25
P = 0.6
P = 60%
Thus, the probability of a value in the sample space being anywhere from 10 to 25 will be 60.
Hence the correct option is B.

Suppose you save $1 the first day of a month, $4 the second day, $16 the third day, and so on. That is, each day you save four times as much as you did the day before. What will you put aside for savings on the seventh day of the month?
Answer:
$ 4096 on the 7th day
Step-by-step explanation:
From the amount earned for the first 3 days it's 1 , 4 , 16 , .... We realize it increases exponentially.
So therefore:
Day 1 =4⁰
Day 2=4¹
Day 3=4²
Day 4=4³
Day 5=4⁴
Day 6=4⁵
Day 7=4⁶
Therefore on day 7 he saves 4⁶ which is $4096

the sum of digits of two digit number is 6 when we interchange the digits it is found that the resulting number is greater than the original number by 18. what is the two digit number?
Answer:
24
Step-by-step explanation:
Original Number :-
Given that ,
Sum of digits is 6 .Let ,
Tens place = x Units place = 6 - xNumber ,
10x + 6 - x = 9x + 6On interchanging the digits :-
Tens place = 6-x Units place = x→ Number = 10( 6-x) + x
→ Number = 60 - 10x + x
→ Number = 60 - 9x
According to Question,
→ 9x + 6 + 18 = 60 - 9x
→ 18x = 60 - 24
→ 18x = 36
→ x = 36/18
→ x = 2
N = 9x + 6 = 18+6 = 24 Hence the required answer is 24.Which set of values could be the side lengths of a 30-60-90 triangle?

Which statement best describes g(x) = cube root x + 6 - 8 and the parent function f(x) = cube root X?
Answer:
Here we can not see the options, so I will answer in a general way.
We have the equations:
g(x) = ∛(x + 6) - 8
f(x) = ∛x
First, let's describe the translations.
Vertical translation:
When we have a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
Such that if N is positive, the translation is upwards
If N is negative, the translation is downwards.
Horizontal translation:
When we have a function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left
If N is negative, the translation is to the right.
Now that we know that, we can compare the functions:
g(x) = ∛(x + 6) - 8
f(x) = ∛x
So if we start with f(x), we can have a horizontal translation of 6 units to the left:
g(x) = f(x + 6)
And then a vertical translation of 8 units down:
g(x) = f(x + 6) - 8
∛(x + 6) - 8 = f(x + 6) - 8
Then g(x) is the function that you get when you apply a horizontal translation of 6 units to the left followed of a vertical translation of 8 units down to the function f(x)

now, our equation is 10=0.75(x).
we are looking for x, so....
10/.75= 13 and 1/3.

Curve is concave downward when the second derivative is negative.
y' = [tex]\frac{x^{2} }{x^{2} -x+4}[/tex] , by the Fundamental Theorem of Calculus
y'' = [tex]\frac{-x^2+8x}{\left(x^2-x+4\right)^2}[/tex] , which has a denominator that is always positive. The numerator [tex]-x^2+8x[/tex] is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.
