What is the equation of the line
Answer:
y = -7
Step-by-step explanation:
The line represents the y-coordinate, because it is a straight line over the x axis, indicating it cant be an x coordinate
Because it is 7 units below the x-axis, it is -7
y = -7

Acellus Find the next term in this arithmetic sequence. 7/2,9/4,1,-1/4,-2/3 ,___
Answer:
-11/4
(I think you meant -3/2 not -2/3 at the end there.)
Step-by-step explanation:
If it is arithmetic, it's going up or down by same number.
So we started with 7/2 and went down to 9/4.
If we can find how much it went down, then we can find the next term after -3/2.
Find difference
7/2-9/4
Find common denominator
14/4-9/4
5/4
So we are going down by 5/4 each time.
That means the following equations should ve true:
7/2-5/4=9/4
9/4-5/4=1
1-5/4=-1/4
-1/4-5/4=-3/2
And all of these are in fact true.
The next term in the sequence will be
-3/2-5/4.
Find common denominator
-6/4-5/4
-11/4

Answer:
9 pi
Step-by-step explanation:
First find the circumference of the circle
C =2 * pi *r
C = 2 * pi *9
C = 18 pi
This is a semicircle which is 1/2 of a circle
Take 1/2 of the circumference
1/2 C = 1/2 ( 18 pi)
1/2 C = 9 pi

Find the missing length of the triangle.
Answer:
29 = c
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2+b^2= c^2 where a and b are the legs and c is the hypotenuse
20^2 + 21^2 = c^2
400 +441 =c^2
841 = c^2
Take the square root of each side
sqrt(841) = sqrt(c^2)
29 = c
Answer:
c = 29 km
Step-by-step explanation:
21² + 20² = c²
441 + 400 = 841
√841 = 29
A student was trying to find the solution to a system of equations, but they were incorrect. Their explanation is shown below.
3x +4y = 10
3x + 4y =2
There are infinite solutions. When I subtract the equations, I get 0x + 0y = 8, so I know that there are infinite solutions to this system of equations.
Explain the mistake that the student made:
Answer:
no solution
Step-by-step explanation:
if you subtract the equations then you get 0 = 8 and this can never be true; therefore there are no solution

At Mathville Middle School, there were 50 students and 50 lockers. Each year for Pi Day (March 14), the students lined up in alphabetical order and performed the following strange ritual. The first student opened every locker. The second student went to every second locker and closed it. The third student went to every third locker and changed it (i.e. if the locker was open, the student closed it; if the locker was closed, the student opened it). In a similar manner, the fourth, fifth, sixth, . . . student changed every fourth, fifth, sixth, . . . locker. After all 50 students had passed by the lockers, which lockers were left open?

What is the factored form of b3 − 1,000?
Kindly, check the attachment below to see the answer.
The factor form of expression (b³ - 1,000) will be;
⇒ (b - 10) (b² + 10b + 100)
What is mean by Factor?
A number or an algebraic expression that divides the another number or algebraic expression is called the factor of same number.
Given that;
The algebraic expression is;
⇒ b³ - 1,000
Now, Solve the expression for the factor form as;
Since, The formula is;
a³ - b³ = (a - b) (a² + ab + b²)
Hence, we factor the expression b³ - 1,000 with the help of above formula as;
⇒ b³ - 1,000
⇒ b³ - 10³
⇒ (b - 10) (b² + b × 10 + 10²)
⇒ (b - 10) (b² + 10b + 100)
Thus, b³ - 1,000 = (b - 10) (b² + 10b + 100)
Therefore,
The factor form of expression (b³ - 1,000) will be;
⇒ (b - 10) (b² + 10b + 100)

What is the area of the shaded portion of the circle?
9514 1404 393
Answer:
(a) (5π -11.6) ft²
Step-by-step explanation:
The shaded area is the area of 1/5 of the circle less the area of the triangle with base 5.8 ft and height 4 ft.
shaded area = 1/5(π(5 ft)²) -(1/2)(5.8 ft)(4 ft)
shaded area = (5π -11.6) ft²

x = 360
The Distance between two points = 360 Km
7b* Consider the average speed at 2/3 distance was V
(45+V)/2 = 54
45+V = 108
V= 108-45= 63km/hr
The average speed for the last 2/3 trip was 63 km/hr
