Classify the pair of angles. Then find the value of x.
Answer:
3) x = 50, vertical angles.
4) x = 20, supplementary angles
5) x = 14, complimentary angles
Step-by-step explanation:
3)vertical angles.
vertical angles are equal.
so, you can make this equation:
67 = x + 17
subtract 17 from both sides of the equation
67 - 17 = x + 17 - 17
67 - 17 = x
50 = x
4)
supplementary angles
supplementary angles add up to 180
so, you can make this equation:
7x + 40 = 180
subtract 40 from both sides of the equation
7x + 40 - 40 = 180 - 40
7x = 180 - 40
7x = 140
divide both sides by 7
7x/7 = 140/7
x = 140/7
x = 20
5)
complimentary angles
complimentary angles add up to 90
so, you can make this equation:
4x + 34 = 90
subtract 34 from both sides of the equation
4x + 34 - 34 = 90 - 34
4x = 90 - 34
4x = 56
divide both sides by 4
4x/4 = 56/4
x = 56/4
x = 14

Answer:
The equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex]
Step-by-step explanation:
We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)
First we need to find slope and y-intercept of the line.
The slope is given i.e. m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, y-intercept can be found using:
[tex]y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17[/tex]
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:
[tex]y=mx+b\\y=-4x-17[/tex]
Now writing in form of Ax + By = C
[tex]y=-4x-17\\4x+y=-17[/tex]
So, the equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex].
plz answer correctly for brainlest, find the mean
Answer:
103
Step-by-step explanation:
108+85+94+103+112+115+98+119+126+105+82+89=1236
1236/12=103
Answer:
103
Step-by-step explanation:
This is the answer because:
1) The mean of a set of numbers is the sum divided by the number of terms:
108 + 85 + 94 + 103 + 112 + 115 + 98 + 119 + 126 + 105 + 82 + 89 = 1236
There are 12 numbers, so divide 1236 with 12:
1236 ÷ 12 = 103
Therefore, the answer is 103.

There are some beads in the box. 40% of them were blue and the rest were red. Adam used all the blue beads and 25% of the red beads to make a bracelet. what percentage of the beads was used to make the bracelet?
Answer:
65% of the beads were used to make the bracelet.
Step-by-step explanation:
40% of the beads were blue which means 60% of the beads were red. If all the blue beads were used that means 40% was used so you add the 25% of the red beads that were used which is why the answer is 65%.
John drives 60 miles per hour on the freeway. If there are 1.60934 kilometers in 1 mile, how many kilometers will John drive in 1 hour? Round your answer to the nearest hundredth.
Answer:

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 8
and AD = 2, what is the length of AC?
Answer:
x = 32
Step-by-step explanation:
∠BCA = ∠DBA (90 - ∠DBC)
∠A = ∠A
ΔABD similar to ΔACB
AC/AB = AB/AD
x / 8 = 8 / 2
x = 32
The length of AC if The right triangle ABC with altitude BD drawn to hypotenuse AC, AB = 8 and AD = 2, is 32.
What is the triangle?Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.
Given:
The right triangle ABC with altitude BD drawn to hypotenuse AC,
AB = 8 and AD = 2,
Check if the triangle Δ ABD similar to Δ ACB
∠ BCA = ∠ DBA (90 - ∠ DBC)
∠ A = ∠ A
Thus, Δ ABD is similar to Δ ACB by AAS similarity,
Calculate the length of AC by using the similarity property,
AC/AB = AB/AD
x / 8 = 8 / 2
x = 32
Thus, the value of AC is 32.

Which expression is equivalent to 4(6 - 2x)?
A)
24 - 8x
B) 24-6x C) 10-8x D) 10-6x
Answer:
the answer is A.
Step-by-step explanation:
to get the you would use the distributive property to multiple the 4 by the two term in the parentheses.
Answer:
It would be A
Step-by-step explanation:
The Key Skill is: Distribution Property
1) We have the expression 4(6-2x)
2) We have to use distribution property to expand this.
The way distribution property works is that we need to multiply the 6 by the 4 on the outside, and also the -2x by the 4 on the outside.
4 x 6 = 24
4 x -2x = -8x
Therefore, the final expression is 24-8x.
The only answer that matches this is A.

Question:
A charter bus travels 225 miles in 4.5 hours. Assume the distance travelled is directly proportional to the time spent.
Write a direct variation equation.
Answer:
[tex]y = 50x[/tex]
Step-by-step explanation:
Let:
y = distance
x = time
So:
[tex]y = 225[/tex] and [tex]x = 4.5[/tex]
Since, they are directly proportional: The following relationship exists
[tex]y = kx[/tex]
Where
k = constant of variation
Substitute values for y and x
[tex]225 = 4.5 * k[/tex]
Make x the subject
[tex]k = \frac{225}{4.5}[/tex]
[tex]k = 50[/tex]
Substitute 50 for k in [tex]y = kx[/tex]
[tex]y = 50x[/tex]

Lexi is making a scale drawing of a soccer field that is 120 yards long and 80 yards wide and the field is that see strong is 30 cm wide how long should the field be in drawing
Answer:
45 cm
Step-by-step explanation:
l = Length of football field is 120 yards
w = Width of football field is 80 yards
The ratio of the sides is [tex]\dfrac{l}{w}=\dfrac{120}{80}=\dfrac{3}{2}[/tex]
Now the width of the field is 30 cm = w'
[tex]\dfrac{l'}{w'}=\dfrac{l}{w}\\\Rightarrow l'=\dfrac{l}{w}\times w'\\\Rightarrow l'=\dfrac{3}{2}\times 30\\\Rightarrow l'=45\ \text{cm}[/tex]
The length of the field in the drawing is 45 cm.

At the beginning of the season, carl had to remove 50 dead orange trees from his farm while each of the remaining trees produced more than 210 oranges. Write mathematical sentences describe the number of oranges produced
Answer:
y > (x - 50) * 210
Step-by-step explanation:
Given :
Number of dead trees = 50
Number of oranges produced by each of the remaining trees > 210
Let total number of trees = x ; total number of oranges produced = y
Hence, number of oranges produced, y
y > number of remaining trees * number of oranges produced per tree
y > (x - 50) * 210

Consider we need to find the first five terms of the given AP and the explicit formula.
Given:
[tex]a_n=a_{n-1}-3[/tex] when [tex]a_1=5[/tex]
To find:
First five terms of the given AP and the explicit formula.
Solution:
We have,
[tex]a_n=a_{n-1}-3[/tex] ...(i)
[tex]a_1=5[/tex], it means first term is 5.
Putting n=2 in (i), we get
[tex]a_2=a_{2-1}-3[/tex]
[tex]a_2=a_{1}-3[/tex]
[tex]a_2=5-3[/tex]
[tex]a_2=2[/tex]
Second term is 2. So, common difference is
[tex]d=a_2-a_1[/tex]
[tex]d=2-5[/tex]
[tex]d=-3[/tex]
First terms is 5 and common difference is -3. So, the first five terms of the AP are 5, 2, -1, -4, -7.
The explicit formula of an AP is
[tex]a_n=a_1+(n-1)d[/tex]
[tex]a_n=5+(n-1)(-3)[/tex]
[tex]a_n=5-3n+3[/tex]
[tex]a_n=8-3n[/tex]
Therefore, the explicit formula of AP is [tex]a_n=8-3n[/tex].

Answer:
The slope is 1/2
Step-by-step explanation:
To get the slope, we select any two points on the line and apply the slope formula
The points are;
(5,4) and (9,6)
The formula for the slope is;
m = (y2-y1)/(x2-x1)
m = (6-4)/(9-5) = 2/4 = 1/2

What is m∠D?
m∠D = °
The measure of Angle D is the same as Angle B which is 63 degrees.
How does an angle form?An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints. The point of their joint is called the vertex of that angle. Those two line segments forming it are called arms of that angle. One arm is fixed, and one arm rotates around that vertex to make angles of different measurements. The fixed arm is called the initial arm. The moving arm is called the terminal arm.
The angle is the degree of rotation that it will take for the moving side to go from the initial side to the position it is currently on.
We are given that m∠B = 63°
Since the lines BC and AD are parallel to each other, they form the quadrilateral ABCD and parallelogram.
Therefore, according to the parallelogram properties,
the measure of Angle D is the same as Angle B which is 63 degrees.
