An angle measures 29° . what is the measure of its complement?
The measure of the complementary angle will be 61°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
An angle measures 29°.
Let 'x' be the complementary angle. Then the measure of the complementary angle is given as,
x + 29° = 90°
Simplify the equation, then we have
x + 29° = 90°
x = 61°
The measure of the complementary angle will be 61°.

Which of the following represents the set of possible rational roots for the polynomial shown below? This question is a review from Algebra 2. Remember that possible rational roots take the form of p/q. Where p is a factor of the constant and q is a factor of the leading coefficient.
2x^3+5x^2-8x-20=0
Answer:
Step-by-step explanation:
Given is the polynomials as
1) [tex]f(x) = x^3+2x^2-x-2[/tex]
The graph of this function has x intercepts as
-2, -1 and 0
Since f(x) =0 has solutions equivalent to x intercepts we see that the roots are
-2,-1 and 0
2) Given is a polynomial as
[tex]f(x) = 2x^3+5x^2-8x-20 =0[/tex]
Using rational roots theorem we find that
the roots possible are ±1.±2,±4,±5,±10,±20,±1/2,±5/2
Using remainder theorem we see that
f(2) =f(-2)=0
By using division, we find that the other factor is 2x+5
Hence roots are 2,-2, -2.5

−7x−50≤−1 AND−6x+70>−2
Answer:
[tex]-7\geq x<12[/tex] and [tex][-7,12)[/tex] in interval notation.
Step-by-step explanation:
We have been given a compound inequality [tex]-7x-50\leq -1\text{ and }-6x+70>-2[/tex]. We are supposed to find the solution of our given inequality.
First of all, we will solve both inequalities separately, then we will combine both solution merging overlapping intervals.
[tex]-7x-50\leq -1[/tex]
[tex]-7x-50+50\leq -1+50[/tex]
[tex]-7x\leq 49[/tex]
Dividing by negative number, flip the inequality sign:
[tex]\frac{-7x}{-7}\geq \frac{49}{-7}[/tex]
[tex]x\geq -7[/tex]
[tex]-6x+70>-2[/tex]
[tex]-6x+70-70>-2-70[/tex]
[tex]-6x>-72[/tex]
Dividing by negative number, flip the inequality sign:
[tex]\frac{-6x}{-6}<\frac{-72}{-6}[/tex]
[tex]x<12[/tex]
Upon merging both intervals, we will get:
[tex]-7\geq x<12[/tex]
Therefore, the solution for our given inequality would be [tex]-7\geq x<12[/tex] and [tex][-7,12)[/tex] in interval notation.

Sound a measures 25 decibels and sound b is 8 times as loud as sound
a. what is the decibel rating of sound b to the nearest integer?
Final answer:
To find the decibel rating of sound b, we calculate the decibel difference between sound a and sound b, which is 9.031 decibels. Adding this to the decibel rating of sound a gives us an approximate decibel rating of 34 for sound b.
Explanation:
To find the decibel rating of sound b, we need to determine how many decibels louder it is compared to sound a. We know that sound b is 8 times as loud as sound a, so we can use the formula for decibel difference:
Decibel difference = 10 * log10(intensity ratio)
Since sound b is 8 times as loud as sound a, the intensity ratio is 8. Plugging this into the formula gives:
Decibel difference = 10 * log10(8) = 10 * 0.9031 = 9.031 decibels
To find the decibel rating of sound b, we add the decibel difference to the decibel rating of sound a:
Decibel rating of sound b = Decibel rating of sound a + Decibel difference = 25 + 9.031 ≈ 34 decibels

What two numbers multiply to -30 and add to 1?
The products of two numbers involves multiplying them.
The two numbers are -5 and 6
Let the numbers be x and y.
So, we have:
[tex]\mathbf{x \times y = -30}[/tex]
[tex]\mathbf{x + y = 1}[/tex]
Make x the subject in [tex]\mathbf{x + y = 1}[/tex]
[tex]\mathbf{x = 1 - y}[/tex]
Substitute [tex]\mathbf{x = 1 - y}[/tex] in [tex]\mathbf{x \times y = -30}[/tex]
[tex]\mathbf{(1 - y)y = -30}[/tex]
Expand
[tex]\mathbf{y - y^2 = -30}[/tex]
So, we have:
[tex]\mathbf{y^2 -y - 30 = 0}[/tex]
Expand
[tex]\mathbf{y^2 -6y + 5y - 30 = 0}[/tex]
Factorize
[tex]\mathbf{y(y -6) + 5(y - 6) = 0}[/tex]
Factor out y - 6
[tex]\mathbf{(y + 5) (y - 6) = 0}[/tex]
Solve for y
[tex]\mathbf{y = -5\ and\ 6}[/tex]
Hence, the two numbers are -5 and 6

In
kite WXYZ, m∠ZWY=43°and m∠XYW=12°.
What is m∠WXY?
Enter your answer in the box.
photo:
Answer: [tex]\angle WXY=125^{\circ}[/tex]
Explanation: Since, a kite has one pair of congruent angles and its main diagonal bisects its opposite angles.
Therefore, According to the given figure,
[tex]\angle WXY=\angle WZY[/tex]
And, WY is the main diagonal which bisects angles ZWX and XYZ.
So, [tex]\angle ZWX =2\times \angle ZWY= 2\times 43^{\circ}=86^{\circ}[/tex]
And, [tex]\angle XYZ =2\times \angle XYW= 2\times 12^{\circ}=24^{\circ}[/tex]
Since, Sum of all angles of a quadrilateral is equal to [tex]360^{\circ}[/tex]
Therefore, [tex]\angle WXY+\angle WZY+\angle XYZ+\angle ZWX=360^{\circ}[/tex]
⇒[tex]2\times \angle WXY+ 86^{\circ}+24^{\circ}=360^{\circ}[/tex]
⇒[tex]2\times \angle WXY=360^{\circ}-110^{\circ}=250{\circ}[/tex]
⇒ [tex]\angle WXY=125^{\circ}[/tex]

Suppose the tree diagram below represents all the students in a high school and that one of these students were chosen at random. If the student is known to be a girl, what is the probability that the student is right-handed?
A. 1/4
B. 3/4
C. 5/6
D. 1/6
The Answer is C 5/6
250/300 reduced and simplified is 5/6
Answer:
The probability that the student is right-handed given that the student is a girl is:
[tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
From the tree diagram we have to find the probability that the students is right handed given that the student is a girl.
Let A denote the event that the student is a girl.
and B denote the event that the student is right handed.
We are asked to find the probability:
P(B|A)
We know that P(B|A) is calculated as:
[tex]P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}[/tex]
There are a total of 500 students.
Out of which 300 are girls.
( i.e. [tex]P(A)=\dfrac{300}{500}=\dfrac{3}{5}[/tex] )
and out of 300 girls 250 are right handed.
( i.e. [tex]P(A\bigcap B)=\dfrac{250}{500}=\dfrac{1}{2}[/tex] )
Hence,
[tex]P(B|A)=\dfrac{\dfrac{1}{2}}{\dfrac{3}{5}}\\\\\\P(B|A)=\dfrac{5}{6}[/tex]
Hence,The probability that the student is right-handed given that the student is a girl is:
[tex]\dfrac{5}{6}[/tex]
