If the measure of Angle B E C is (2 x + 3) degrees and x = 30, which expression could represent the measure of Angle A E D?
Lines A C and B D intersect at point E.
(4 x minus 3) degrees
(3 x minus 27) degrees
(5 x minus 33) degrees
(x + 43) degrees
Answer:
(3x−27)o
Step-by-step explanation:
we know that
m\angle BEC=m\angle AEDm∠BEC=m∠AED ----> by vertical angles
we have
m\angle BEC=(2x+3)^om∠BEC=(2x+3)o
The value of x is given
x=30
so
m\angle BEC=(2(30)+3)=63^om∠BEC=(2(30)+3)=63o
That means that the measure of angle AED is also 63 degrees
so
The expression that could represent the measure of Angle A E D is
(3x-27)^o(3x−27)o
because
For x=30
(3(30)-27)=63^o(3(30)−27)=63o
Answer:
(3x−27)o

What is the slope of a line perpendicular to the line whose equation is 10 x + 6 y = − 84 10x+6y=−84.
Answer:
3/5
Step-by-step explanation:
The equation of a line is written as
y = mx + b where
m is the slope
b is the y-intercept.
We put the given equation above in that form
10x + 6y = - 84
6y = -10x - 84
Divide both sides by 6
y = -10x/6 - 84/6
y = -5x/3 - 14
y = -5/3x - 14
The slope of this line is -5/3
But we are told that: the slope of the line is perpendicular to the line
Hence: we find the reciprocal of , -5/3
This is = 3/5
Therefore, the slope of a line perpendicular to the line whose equation is 10x + 6y = −84 is 3/5

What number is she thinking of?
Question:
Sue is thinking of a number 3/8 of 88 = 1/3 of her number
what number is she thinking of
Answer:
[tex]x = 99[/tex]
Step-by-step explanation:
Represent the number with x.
So, we have:
[tex]\frac{3}{8} * 88 = \frac{1}{3} *x[/tex]
Multiply through by 3
[tex]3 * \frac{3}{8} * 88 = \frac{1}{3} *x * 3[/tex]
[tex]3 * \frac{3}{8} * 88 = x[/tex]
[tex]3 * 3 * 11 = x[/tex]
[tex]99= x[/tex]
[tex]x = 99[/tex]
Hence, she is thinking of 99

Answer:
x = 26
Step-by-step explanation:
1. Information
One can partition this figure into three different parts, two congruent triangles, and one rectangle. To find the value of x, one has to find the base of the two triangles, and then the base of the rectangle. Since opposite sides are congruent, the base of the rectangles is 10. To find the base of the triangle, one has to use the Pythagorean theorem.
2. Base of the rectangle
Again, opposite sides are congruent, hence the base of the rectangle is equivalent to the top part. Hence the base is 10.
3. Base of the triangle
Use the Pythagorean theorem;
[tex]a^{2}+b^{2} = c^{2}\\a-leg\\b-leg\\c-hypotenuse[/tex]
Substitute in the given value and solve
[tex]a^{2}+15^{2} = 17^{2}\\a^{2} + 225 = 289\\a^{2} = 64\\a = 8[/tex]
4. Finding x
There are two congruent trinagles, hence one has to add the base of the triangle twice. The equation will be
x = base_of_triangle + base_of_rectagle + base_of_triangle
x = 8 + 10 + 8
x = 26

Clare went to a concession stand that sells pretzels for $3.25, drinks for $1.85, and bags of popcorn for $0.99 each. She bought at least one of each item and spent no more than $10. Could Clare have purchased 2 pretzels, 2 drinks, and 2 bags of popcorn? Explain your reasoning. Check your work with the video when you are ready
Answer:
No.
Step-by-step explanation:
Price of each pretzel = $3.25
Price of each drink = $1.85
Price of each bag of popcorn = $0.99
Maximum money to be spent = $10
Price of two pretzels = $3.25 [tex]\times[/tex] 2 = $6.5
Price of two drink = $1.85 [tex]\times[/tex] 2 = $3.70
Price of two bags of popcorn = $0.99 [tex]\times[/tex] 2 = $1.98
Total money spent for buying two items of each type = $6.5 + $3.70 + $1.98 = $12.18
The money spent when 2 pretzels, 2 drinks and 2 bags of popcorn are bought is $12.18.
But maximum money available is $10.
Therefore, Clare would not be able to buy 2 pretzels, 2 drinks and 2 bags of popcorn with the amount of money available.

Given the frequency table, what percentage of the students that like rock are also in grades 11–12? Round to the nearest whole percent.
Band Preference for School Dance
Rap Rock Country Row totals
Grades 9–10 40 30 55 125
Grades 11–12 60 25 35 120
Column totals 100 55 90 245
10%
21%
25%
45%
Answer:
d. 45%
Step-by-step explanation:
According to the frequency table there are 30 sudents who like rock in grades 9-10 and 25 students that like rock and are in grades 11-12.
25 ÷ 55 = n ÷ 100
25 · 100 = 55 · n
2500 ÷ 55 = n n = 45.454545 n = 45%
55 is the total amount of students that like rock
25 is the total amount of students that like rock in grades 11-12
100 is the total percentage

Question is: Work of the bearing of Q from P.
Answer:
The bearing of Q from P is [tex]75^{o}[/tex].
Step-by-step explanation:
The diagram shows the locations of each point with respect to their bearings. As in bearing, angles are measured with the north axis taken as a reference point.
So that,
the bearing of Q from P would be the value of angle NPQ.
<NPQ = [tex]180^{o}[/tex] - <NQP (alternate angle principle)
= [tex]180^{o}[/tex] - [tex]105^{o}[/tex]
= [tex]75^{o}[/tex]
Thus, the bearing of Q from P is [tex]75^{o}[/tex].
Furthermore, the bearing of P from Q can be determined as;
= [tex]360^{0}[/tex] - [tex]105^{o}[/tex]
= [tex]255^{o}[/tex]
The bearing of P from Q is [tex]255^{o}[/tex].
