Answer:
The actual measure of ∠1 = 40°
Step-by-step explanation:
We are given: ∠1 = 2x+6 and ∠2 = 8x+4
and both angles are supplementary. we need to find the actual measure of ∠1
Supplementary angles: If the angles are supplementary their sum is equal to 180°
In our case ∠1 +∠2 = 180°
2x+6+8x+4=180
Solving the equation to find x, then we can find the actual measure of ∠1
[tex]2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17[/tex]
So, value of x = 17
Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6
[tex]\angle1=2(17)+6\\\angle1=34+6\\\angle1=40[/tex]
So, the actual measure of ∠1 = 40°
Translate the following statement: "Your grade, g, must be at least
75 to pass this class."
Answer:
"Your grade, g, must be at least 75 to pass this class'' is translated as:
g ≥︎ 75Step-by-step explanation:
Given the grade is denoted by 'g'.
In algebra '≥︎' denotes that something must be 'greater than or equal to'. In other words, it means 'at least'.
As the gade must be at least 75, it means it can be greater than 75, but it can not be less than 75.
Therefore, "Your grade, g, must be at least 75 to pass this class'' is translated as:
g ≥︎ 75Plz I'm sooooo confuzzled: If you reflect any shape across the x-axis and then across the y-axis, do you get the same result that you would if you rotated it 180° about the origin? What does that mean?
Answer:
the answer is true
Step-by-step explanation:
If the shape is in the upper left quadrant then you reflect it across the x-axis it would be in the lower left quadrant, next you reflect across the y-axis it would be in the lower right quadrant, finally, if you rotate it 180 degrees it would be where it started.
Answer:
it's correct because even though rotating 90° is not the same as reflecting about the y-axis, when you reflect again about the x-axis, it becomes the same as reflecting an additional 90°.
so reflecting about y and then about x is the same as rotating 180°.
Step-by-step explanation:
if you reflect (x, y) in 180° it becomes (-x,-y)
when you reflect about the y-axis, (x,y) becomes (-x,y).
when you reflect again about the x-axis, (-x,y) becomes (-x,-y) which is the same as the 180°
You make a necklace using blue,purple and green beads in ratio of 1:3:5. You use a total of 126 beads. How many green beads are in the necklace?
Answer:
Step-by-step explanation:
x + 3x + 5x = 126
9x = 126
x = 14 (blue beads)
3(14) = 42 (purple beads)
5(14) = 70 (green beads)
A museum has 6,000 visitors in its first month of operation. The museum staff predicts that the number of visitors will increase by 5% each month. Assuming that this prediction is true, how many visitors does the museum expect on the 7th month of operation?

8100 visitors in 7th month.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
given:
Visitor in first month= 6000
If the visitors will increase at the rate of 5% then
Visitors in second month
=6000+ 6000 x 5/100
=6000 + 300
=6000
So, the visitors in 7 month
=6000+ 7(300)
=6000 +2100
=8100
Hence, there 8100 visitors in 7th month.

During the big storm, 29 in. of snow fell in 8 hours. Find the rate of snowfall in inches per hour.
Answer:
3 5/8 inches of snow per hour
Step-by-step explanation:
29 divided by 8 = 3.625
(3 5/8)
if 29 inches for 8 hours, and you need to find how much snow in one hour, you can get 1 hour from 8 hours by doing 8 divided by 8. You use the same number to find the snow, divide 29 by 8 and you get the rate at which snow builds up.

The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 2.17 square centimeters. The perimeter of the octagon is 48 centimeters. What is the length of each side of the octagon?
Answer:
The length of each side of the Octagon is 6 centimeters
Step-by-step explanation:
An Octagon is an 8 sided polygon
The perimeter of the octagon can be obtained by the addition of all the sides of the octagon
Since it is a regular octagon, it means that all the sides are of equal length
Mathematically, what this mean is that the perimeter of the Octagon is simply 8s
where s is the length of the side of the Octagon
Thus, mathematically, the length of each side of the Octagon will be 48/8 = 6 centimeters

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (3, 6), has a vertex at (5, 2), and goes through (7, 6).
What is the equation of the translated function, g(x), if
f(x) = x2?
A: g(x) = (x + 5)2 + 2
B: g(x) = (x + 2)2 + 5
C: g(x) = (x – 2)2 + 5
D: g(x) = (x – 5)2 + 2
Answer:
D
Step-by-step explanation:
Option 4.
The vertex form of a parabola is
where, a is a constant (h,k) is the vertex.
The given function is
The vertex of the function is (0,0) and it goes through (-2, 4) and (2, 4).
It is given that the vertex of function g(x) is at (5,2).
Substitute h=5 and k=2 in the equation.
g(x) is passed through (3, 6).
Divide both sides by 4.
Substitute a=1 in equation (2).
The function g(x) is g(x) =(x-2)2+5) .
Therefore, the correct option is 4.

Step-by-step explanation:
5.46+1
230+1
231
answer this?
Answer:
yes
Step-by-step explanation:
Equate 5n + 1 and 46 to find n, that is
5n + 1 = 46 ( subtract 1 from both sides )
5n = 45 ( divide both sides by 5 )
n = 9
Thus 46 is the ninth term in the sequence
Martin traveled at an average rate of 40 miles per hour for the first half of his trip. For the second half of his trip, he traveled at a rate of 60 miles per hour. How far did he travel in the 4-hour trip?
Answer:
Total distance traveled = 200 miles
Step-by-step explanation:
Total time taken for the trip = 4 hours
∴ The trip can be divided into two halves of 2 hours each.
1st half:
speed = 40 miles per hour
distance = speed × time
when time = 2 hours
distance = 40 × 2 = 80 miles
2nd half:
distance = speed × time
speed = 60 miles per hour
time = 2 hours
∴ distance = 60 × 2 = 120 miles
Combined distance traveled = 80 + 120 = 200 miles

Lines a and b are parallel. Line c is a transversal. FInd the measures of all angles formed by a, b, and c, given each scenario. One of the angles measures 150 degrees.
Answer:
30° and 150°
Step-by-step explanation:
Given
Parallel lines a and b
Transversal c
Angle = 150°

Determine the list of possible angles
A transversal divides a parallel line into two measure which add up to 180°
Given that one of the angles is 150°, the other angle would be 180° - 150°
