One of the angles in an isosceles triangle is 74°.
What could the other two angles be?
Answer:
we know that isoceles has pair of angle with same measurement and sum of interior angle of triangle is 180°
Step-by-step explanation:
Let other angle be x
x+x+74°= 180°
=> 2x = 180°-74°
=>x = 106°/2
=> x= 53°
If one of the angles in an isosceles triangle is 74°. Then the other two angles will be 53°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In an isosceles triangle, two angles and their opposite sides are equal.
One of the angles in an isosceles triangle is 74°.
Let the other angle be x.
Then the value of x will be
x + x + 74° = 180°
2x = 180° – 74°
2x = 106°
x = 53°

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The number of quarters = 1
So , the value of quarters = $ 0.25
The number of cents = 2
So , the value of cents = $ 0.20
The number of nickels = 2
So , the value of nickels = $ 10
And , the equation will be
A = value of quarters + value of cents + value of nickels
On simplifying , we get
A = 0.25 + 0.20 + 0.10
A = $ 0.55
Therefore , the value of the coins is A = $ 0.55
Hence , the equation is A = $ 0.55

Answer:
12
Step-by-step explanation:
Pythagoras Theorem is clearly used in this question.
To Calculate the Hypotenuse:
C = [tex]\sqrt{a^2+b^2}[/tex]
The Adjacent angle has already given as 9, so you can factor that into the question.
In Order to calculate the Opposite angle you need to use the following formula.
[tex]b = \sqrt{c^2-a^2}[/tex]
With the integers we already have for both Hypotenuse and Adjacent factored in this will be your equation:
[tex]b = \sqrt{15^2-9^2} = 12[/tex]

What is the definition of Linear Angle?
A pair of angles that lie on the same plane, have a common vertex, and share a common side
or
A pair of angles that have a common side and same vertex, and the sides points in opposite directions.
or
A pair of angles that are opposite of each other and formed by two intersecting lines.
Answer:
The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles. The adjacent angles are the angles which have a common vertex.

Find an explicit rule for each geometric sequence using subscript notation. Use a calculator and round your answers to the nearest tenth if necessary.
The fifth term of a geometric sequence is 7. The sixth term is 3.5.
Answer:
aₙ = 224(1/2)ⁿStep-by-step explanation:
Given GP with:
a₅ = 7a₆ = 3.5We can find the common ratio:
r = 3.5/7 = 1/2Using the nth term formula we can work out the first term:
aₙ = a₁rⁿ⁻¹a₅ = a₁(1/2)⁴7 = a₁ (1/16)a₁ = 7*16a₁ = 112So the explicit rule is:
aₙ = 112(1/2)ⁿ⁻¹ = 224(1/2)ⁿSuppose a normal distribution has a mean of 222 and a standard deviation of

Answer:
C) 53.3%
The probability that a data value is between 206 and 230
P( 206 ≤X≤230) = 0.5328 = 53.3%
Step-by-step explanation:
Explanation
Given that Mean of the Normal distribution(μ) = 222
Given that the standard deviation of the Normal distribution (σ) = 16
Let 'X' be the random variable in the Normal distribution
we have to find that the probability that a data value is between 206 and 230
solution:-
Step(i):-
Let 'X' = 206
[tex]Z = \frac{x^{-}-mean }{S.D} = \frac{206-222}{16} = -1[/tex]
Let X = 230
[tex]Z = \frac{x-mean }{S.D} = \frac{230-222}{16} = 0.5[/tex]
Step(ii):-
The probability that a data value is between 206 and 230
P( 206 ≤X≤230) = P( -1≤Z≤0.5)
= |A(0.5)+A(-1)|
= 0.1915+0.3413
= 0.5328
final answer:-
The probability that a data value is between 206 and 230
P( 206 ≤X≤230) = 0.5328 = 53.3%

Which measure should be used to summarize the data?
Mean?
Median?
Mode?
Answer:
mean
Step-by-step explanation:
The method to summarize the data will be mean
The mean of the laps of swim team is 84.1 laps
What is Mean?
The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the data be represented by the set A
Let the mean of the data set be M
The value of set A = { 77 , 79 , 80 , 82 , 84 , 85 , 86 , 87 , 90 , 91 }
The total number of data elements in the set = 10
Now , since all the data elements are distributed normally and does have a central point
So , it follows normal distribution
Therefore , the mean of the data will be
Mean M = Sum of Values / Number of Values
Mean = ( 77 + 79 + 80 + 82 + 84 + 85 + 86 + 87 + 90 + 91 ) / 10
Mean = 841 / 10
Mean M = 84.1 laps
Therefore , the value of M is 84.1
Hence , The method to summarize the data will be mean
The mean of the laps of swim team is 84.1 laps

Are 2(x - 3) + 1 and 2x + 6 equivalent expressions
Answer:
No.
Step-by-step explanation:
2(x-3) + 1 = 2x - 6 + 1 = 2x - 5
2x + 6 ≠ 2x -5, so no, they aren't equivalent.
The expression 2(x - 3) + 1 and 2x + 6 are not Equivalent.
What is Equivalent Expression?Equivalent expressions are expressions that perform the same function notwithstanding their appearance. If two algebraic expressions are equivalent, they have the same value when the same value(s) for the variable are used (s).
We have two expressions to compare 2(x- 3) + 1 and 2x +6 .
Now, simplifying the first expression as
= 2(x -3) + 1
= 2x - 6 +1
= 2x - 5
and, the second expression is 2x + 6.
Thus, both of expression are not Equivalent.
