how many terms of the AP: 24,21,18 must be taken so that thier sum is 78?
Answers
common difference, d = 21-24 = -3
let the number of terms to get sum 78 is n.
S_n=78\\ \\ \Rightarrow \frac{n}{2}(2a+(n-1)d)=78\\ \\ \Rightarrow \frac{n}{2}(2 \times 24+(n-1)(-3))=78\\ \\ \Rightarrow n(48-3n+3)=78 \times 2\\ \\ \Rightarrow -3n^2+51n-156=0\\ \\ \Rightarrow 3n^2-51n+156=0
Solving the quadratic equation, we get n=4 and n=13.
So you can take either 4 terms or 13 terms to get the sum 78.

Find the value of that makes m ll n.
Answers
Answer: x = 108
Step-by-step explanation: In this problem, we're given a diagram and
we're asked to find the value of x that would make m ll n.
We can see that the angles that are marked in the diagram
are same-side interior angles since they lie on the same side
of the transversal and they lie on the interior of lines m and n.
Therefore, in order for line m to be parallel to line n,
these angles must be supplementary.
In other words, they must add to 180 degrees.
So we can setup the equation x + 72 = 180.
Subtracting 72 from both sides gives us x = 108.
So the value of x that would make line m ll n is 108.

The discount allowed in a store for a cash payment is 6%. Find what a buyer pays for an article whose marked prices $567.50
Answers
Answer:
A buyer would have to pay $533.45 for an article whose marked prices $567.50.
Step-by-step explanation:
Marked price = $567.50
Discount=6%
Price after discount = 567.50 - 6% of 567.50
[tex]=\:567.50\:-\frac{6}{100}\:\times \:567.50[/tex]
[tex]=567.5-34.05[/tex]

This figure is made from a part of a square and a part of a circle.
What is the perimeter of this figure, to the nearest unit? ______ units
Answers
Answer:
38 units (rounded off to the nearest unit)
Step-by-step explanation:
Find the perimeter of the circle part, if the circle section is a 90degree slice, then it is a quarter of the full circle's circumference[tex]Circumference=pi\times 2radius\\C=\pi \times 2(5)\\C=10\pi[/tex] now find a quarter of this then[tex]SectionCircumference=\frac{5}{2}\pi[/tex] Then find the perimeter of the whole thing by adding the side [tex]P=10+10+5+5+\frac{5}{2}\pi =37.85[/tex]The perimeter of the given figure will be 38 units.
What is perimeter?Its the sum of length of the sides used to made the given figure.
We are given that Measures of three linear sides as 5, 10, 10, 5 units.
Radius of the circular part = 5 units
Since Perimeter of a polygon = Measure of the circumference of the polygon
The Perimeter of the figure = measure of the three straight lines + measure of the circumference of the quarter circle
Thus Measure of linear sides = 5 + 10 + 10 + 5 = 30 units
Circumference of the quarter circle = 2πr
= 2π(5)
= 7.85 units
Perimeter of the figure = 30 + 7.85
= 37.85
≈ 38 units
Therefore, the perimeter will be 38 units.

Answers
Complete question :
On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?
Answer:
1.6 hours
Step-by-step explanation:
Given the function :
Time t taken for flying distance d is given by:
t = 1/500 * d
Tine taken to fly 800 miles;
d = 800 miles
t = 1/500 * (800)
t = 800 / 500
t = 1.6
Hence, time t = 1.6 hours

The slope of the line that passes through the points (9, 11) and (3,6) is what
Answers
(y2 - y1) / (x2 - x1)
Our points are (9, 11) and (3, 6).
Therefore we can determine:
y2 = 6
y1 = 11
x2 = 3
x1 = 9
Substitute these into the formula:
(y2 - y1) / (x2 - x1)
(6 - 11) / (3 - 9)
Solve:
(6 - 11) / (3 - 9)
-5 / -6
Reduce the fraction with -1:
Slope (m) = 5 / 6
The equaiton of the line is y = (5/6)x + 7/2. Then the slope of the line is 5/6.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The two points are (9, 11) and (3, 6).
The equation of the line that passes through (9, 11) and (3, 6) will be given as,
(y - 6) = [(11 - 6) / (9 - 3)](x - 3)
y - 6 = (5/6)(x - 3)
y - 6 = (5/6)x - 5/2
y = (5/6)x + 7/2
The equaiton of the line is y = (5/6)x + 7/2. Then the slope of the line is 5/6.

Points X and Z are on a number line, and point Y partitions
line XZ into two parts so that the ratio of the length of line
segment XY to the length of line segment YZ is 5:7. The
coordinate of X is 0.4, and the coordinate of Y is 5.8. What
is the coordinate of Z?
Answers
Answer:
The coordinate of [tex]Z[/tex] is 13.36.
Step-by-step explanation:
According to the statement, we have the following information:
[tex]\frac{XY}{XZ} = \frac{5}{12}[/tex] (1)
[tex]\frac{YZ}{XZ} = \frac{7}{12}[/tex] (2)
[tex]X = 0.4[/tex] (3)
[tex]Y = 5.8[/tex] (4)
From (2), we have the following expression:
[tex]YZ = \frac{7}{12}\cdot XZ[/tex]
[tex]Y-Z =\frac{7}{12}\cdot (X-Z)[/tex]
[tex]Y - Z = \frac{7}{12}\cdot X -\frac{7}{12}\cdot Z[/tex]
[tex]Y-\frac{7}{12}\cdot X = Z-\frac{7}{12}\cdot Z[/tex]
[tex]\frac{5}{12}\cdot Z = Y-\frac{7}{12}\cdot X[/tex]
[tex]5\cdot Z = 12\cdot Y-7\cdot X[/tex]
[tex]Z = \frac{12}{5}\cdot Y-\frac{7}{5}\cdot X[/tex] (5)
If we know that [tex]Y = 5.8[/tex] and [tex]X = 0.4[/tex], then the coordinate of [tex]Z[/tex] is:
[tex]Z = \frac{12}{5}\cdot (5.8)-\frac{7}{5}\cdot (0.4)[/tex]
[tex]Z = 13.36[/tex]
The coordinate of [tex]Z[/tex] is 13.36.

100 pointsssss!!
what are the pointsss???? Graph the function.
f(x)=−15x+4
Answers
Answer:
Step-by-step explanation:
I'd suggest you find the two intercepts and draw a line through them.
y-intercept: value of y when x = 0. Here, f(0) = -15(0) + 4, so the y intercept is the point (0, 4).
x-intercept: value of x when y = 0. Letting f(x) = y = 0, we get
0 = -15x + 4, so that 15x = 4, and x = 4/15. The x-intercept is (4/15, 0).
Plot the points (0, 4) and (4/15, 0) and draw a line thru them.

Answer:
[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)[/tex]
Step-by-step explanation:
To see which equations have the slope of 3/4, we just need to focus on the right half of the equations to see what the multiplier of x is.
Equations 1 and 3 can be eliminated because they have a slope of [tex]\frac{1}{3}[/tex] and 4 respectively.
Now we can decide between 2 and 4 by plugging in the point [tex](4,\frac{1}{3})[/tex] to see which works properly.
Simplify equation 2
[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)\\\\y-\frac{1}{3} =\frac{3}{4}x-3\\\\y=\frac{3}{4}x-\frac{8}{3}[/tex]
Plug in the point
[tex]\frac{1}{3} =\frac{3}{4}(4)-\frac{8}{3} \\ \\\frac{1}{3} =3-\frac{8}{3} \\\\\frac{1}{3} =\frac{9}{3} -\frac{8}{3} \\\\\frac{1}{3} = \frac{1}{3}[/tex]
This checks out, so equation 2 is your answer.
