What is the measure of ∠1
A: 56°
B: 73°
C: 107°
ANSWER FAST HURRY! WILL MARK BRAINLEIST WORTH 100 POINTS
Answer: 73
Step-by-step explanation:
Angle B is 180-107=73
Angle 1 is equivalent to B and it is 73
Answer:
C. ∠1 = 73°
Step-by-step explanation:
Angles on a straight line add up to 180°
Therefore:
⇒ ∠1 + 107° = 180°
Subtract 107° from both sides:
⇒ ∠1 + 107° - 107° = 180° - 107°
⇒ ∠1 = 73°
In how many ways can 8 people be seated in a row of chairs if three of the people, John, Wilma, and Paul, refuse to sit in three consecutive seats?
Answer:
I think it's easiest to count the ways that they can consecutively sit together and subtract this from the total number of seating arrangements.
There are 6 groups of 3 consecutive seats. Within each group there are 3!=6 ways the three people can be arranged
Then the remaining 5 people can be arranged 5!=120 ways in the remaining seats.
So there are 6*6*120 = 4320 arrangements where they DO sit consecutively
There are 8! = 40320 total arrangements.
So there are 40320 - 4320 = 36000 arrangements where the 3 do not sit consecutively.

a/b + 8/b = ?/b what’s the numerator for the following rational expression
Answer:
Numerator: A + 8
Complete Form: [tex]\frac{A+8}{b}[/tex]
Step-by-step explanation:
Hello!
If we have two fractions that are being added or subtracted with the same denominator, we can simply add up the numerators and keep it over the same denominator.
Let's use this question as an example:
[tex]\frac Ab + \frac 8b = \frac ?b[/tex][tex]\frac {A + 8}{b}[/tex]The problem is basically saying, "If I took A slices from b slices and 8 slices from b slices, how many slices would I have?"
The answer would be A + 8 slices.

In the graph above, the coordinates of the vertices of QPR are Q(3, 0), P(5, 6), and R(7, 0). If AQPR is reflected across
the x-axis to create Q'P'R', find the coordinates of R.
A. (-7,0)
B. (3,0)
C. (5,-6)
D. (7,0)
Answer:
D. (7, 0)
Step-by-step explanation:
The rule for a reflection over the y-axis is (x, y) → (x, -y)
This means that the x-values stay the same while the y-values change.
Q(x, y) → (x, -y)
Q(3, 0) → (3, 0)
Q'(3, 0)
P(x, y) → (x, -y)
P(5, 6) → (5, -6)
P'(5, -6)
R(x, y) → (x, -y)
R(7, 0) → (7, 0)
R'(7, 0)
Therefore, the correct answer is D.

2) Tara is trying to find the nth term of the arithmetic sequence 5,8,11, and 14…. Which expression can Tara use to find the nth term? What is the 15th term of the sequence?
Answer:
Below in bold.
Step-by-step explanation:
Nth term an = a1 + d(n - 1) where a1 = term 1 and d = common difference.
Here a1 = 5 and d = 8-5 = 3.
So an = 5 + 3(n - 1)
15th term a15
= 5 + 3(15 - 1)
= 5 + 42
= 47.

Suppose Jonathan eats 6 packages of pemmican. He also eats some biscuits. Create an equation that models the total number of calories Jonathan consumes, y, based on the number of biscuits he eats, x, and the 6 packages of pemmican.
Using proportions, it is found that the equation that models the total number of calories Jonathan consumes is given by:
y = 810 + 75x.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem:
Each biscuit has 75 calories, hence x biscuits will have 75x calories.Each package of pemmican has 135 calories, hence 6 packages will have 6 x 135 = 810 calories.Thus, the equation is given by:
y = 810 + 75x.

Second = 5(2) - 3 = 7
Third = 5(3) - 3 = 12.
Find sin D, sin E, cos D, and cos E. Write each answer as a fraction in simplest form
The value of sin D, sin E , cos D , and cos E in simplest fraction form are as follows:
Sin D = 4 / 5
sin E = 3 / 5
cos D = 3 / 5
cos E = 4 / 5
Trigonometric ratios:The simplest trigonometric ratios expression are as follows:
sin ∅ = opposite / hypotenusecos ∅ = adjacent / hypotenusetan ∅ = opposite / adjacentTherefore,
Sin D = opposite / hypotenuse = 12 / 15 = 4 / 5
sin E = opposite / hypotenuse = 9 / 15 = 3 / 5
cos D = adjacent / hypotenuse = 9 / 15 = 3 / 5

Con= addjacent/ hypotnuse
if you cant tell which side the hypotnues if on, it is always opposite from the 90 degree mark.
Now that you know how to make the fraction for Sin and Con, you would have to use a graphing calulator, plug in Sin^-1 or Con^-1 what ever the sign is and put the fractions in ( ) next to it and it will give you the decmle. Also using a graphing calculator is 100% allowed in this type of math.

Determine the coordinate of the point where
y=x−6 crosses the x-axis.
Answer:
(6, 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x
0 = x - 6 ( add 6 to both sides )
6 = x
the line crosses the x- axis at (6, 0 )
Instead of y write 0:
0=x-6
Now solve for x :0=x-6
Add 6 on both sides6=x or x=6
We know the x coordinate of the point that intersects the x axis; the y coordinate is always 0.
Coordinates of the point ↓(6, 0)

Roy wants to make a path from one corner of his yard to the other as shown below. the path will be 4 feet wide. he wants to find the area of lawn that remains. a rectangle has a height of 40 feet and a base of 15 feet. a 4 feet wide path forms a parallelogram inside of the rectangle. roy claims that the area of the lawn is 300 square feet since it covers exactly one-half of the yard. which statement about his claim is correct? he is incorrect. the path will have an area of (4) (40) = 160 sq ft. the yard has an area of 600 sq ft. the area of the lawn will be the difference of the yard and path, so it is 440 sq ft. he is incorrect. the path will have an area of one-half (4) (40) = 80 sq ft. the yard has an area of 300 sq ft. the area of the lawn will be the difference of the yard and path, so it is 220 sq ft. he is incorrect. the path will have an area of (4) (40) = 160 sq ft. the yard has an area of 300 sq ft. the area of the lawn will be the difference of the yard and path, so it is 140 sq ft. he is incorrect. the path will have an area of (9) (40) = 360 sq ft. the yard has an area of 600 sq ft. the area of the lawn will be the difference of the yard and path, so it is 240 sq ft.
The incorrect claim is A. He is incorrect. The path will have an area of (4)(40)=160 sq ft. The yard has an area of 600 sq ft. The area of the lawn will be the difference of the yard and path, so it is 440 sq ft.
What is an Area?This refers to the quantity used in mathematics to show the extent of a two-dimensional region, shape, or planar lamina, in the plane.
Hence, because Roy wants to make a path from one corner of his yard to the other, he makes an incorrect claim about the area of the yard and the lawn, and option A is the correct answer.

A boy leaves home at 7:30 a.m and cycles to school, 6 km away, arriving at 7:45 a.m. The average speed of the boy as he cycles, in kmh, is (A) 32 (B) 24 (C) 18 (D) 16
Answer:
B) 24
Step-by-step explanation:
distance = 6 km
we want the speed in km/h, so let's turn everything into either km or h if possible
time = 7:45 am - 7: 30 am = 15 minutes
60 minutes = 1 hour
1 hour / 60 minutes = 1
15 minutes * 1 = 15 minutes * 1 hour/60 minutes = 15 / 60 hours = 1/4 hours = 0.25 hours
note that we multiply by 1 hour / 60 minutes, not 60 minutes/ 1 hour. this is because we want the minutes to cross out -- because the original is given in minutes ( 15 minutes = 15 minutes/1) and is in the numerator, we need minutes in the denominator of 1 hour/60 minutes to cross it out
km = 6
h = 0.25
km/h = 6/0.25 = 24

At the alternative hypotheses, it is tested if it is different, hence:
