Answer:
Elena needs to sell 60 tickets
Answer:
Elena must sell 90 tickets to earn $900
Step-by-step explanation:
Divide the total money needed by how much each ticket costs:
900 ÷ 10 = 90
If you're talking about how many more tickets are needed:
Subtract the total tickets needed by how many tickets Elena already sold
90 - 30 = 60 more tickets needed

Answer:
C
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = [tex]x^{4}[/tex] + 7 ( subtract 7 from both sides )
y - 7 = [tex]x^{4}[/tex] ( take the fourth root of both sides )
[tex]\sqrt[4]{y-7}[/tex] = x
Change y back into terms of x where x is g(x)
g(x) = [tex]\sqrt[4]{x-7}[/tex] , x ≥ 7
What is the solution to the equation One-third (x minus 2) = one-fifth (x + 4) + 2? x = 12 x = 14 x = 16 x = 26
Answer:
x = 26
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (x - 2) = [tex]\frac{1}{5}[/tex] (x + 4) + 2
Multiply through by 15 to clear the fractions
5(x - 2) =3(x + 4) + 30 ← distribute and simplify both sides
5x - 10 = 3x + 12 + 30, that is
5x - 10 = 3x + 42 ( subtract 3x from both sides )
2x - 10 = 42 ( add 10 to both sides )
2x = 52 ( divide both sides by 2 )
x = 26
Kaya rented a limousine for prom. The company charges a cleaning fee of $100 and an hourly rate of $45. Her total cost for the night was $437.50. For how many hours did Kaya rent the limousine?
Answer:
Number of hours= 7.5
Step-by-step explanation:
Giving the following information:
The company charges a cleaning fee of $100 and an hourly rate of $45.
Her total cost for the night was $437.50
First, we need to structure the total cost formula:
Total cost= 100 + 45*x
x= number of hours
437.5= 100 + 45x
337.5/45= x
x= 7.5
Number of hours= 7.5
Answer:
Kaya rented the limo for about 7.5 hours
Hope this helps! good luck :)

How to draw a shifted figure if the shifts are provided?Suppose the graph is drawn on the coordinate plane.
Let the shifting be (x,y) → (x+a, y+b)
Then, add 'a' to all x coordinates of the graph's points. Add 'b' to all y coordinates of the graph's points.
The resultant set of new points will be plotted.
Thus it is called origin shift since we think of it as the origin was picked and placed at the point (a,b)(in this case) along with those two axes (x and y axes) and now everything will be measured from this new axes' frame.
Therefore, the coordinates of the vertices after a translation 5 units right and 2 units up.
C =(1,-8)
D =(7,-8)
E =(7,0)
F =(1,0)

Cynthia besch  wants to buy a rug for a room that is 21 feet wide and 29 feet long. she wants to leave a uniform strip floor around the rug. she can afford to buy 345 square fee of carpeting. what dimensions should the rug have
Step-by-step explanation:
Let x be the width of the uniform strip floor around the rug.
Then the width of the rug is (21 - 2x) and the length of the rug is (29 - 2x).
(21 - 2x)(29 - 2x) = 345
609 - 100x + 4x^2 = 345
4x^2 - 100x + 264 = 0
x^2 - 25x + 66 = 0
(x - 22)(x - 3) = 0
x = 3 or x = 22 (rejected as x must be less that the width of the room)
Hence the width of the rug is 21 - 2(3) = 15 feet and the length of the rug is 29 - 2(3) = 23 feet.

Answer:
AC= 22
Step-by-step explanation:

The numerical length of AC is 22 units.
What is a line segment?In geometry, a line segment is a part of a line that is bounded by two distinct end points,and contains every point on the line that is between its endpoints.
Now it is given that,
Point B is on line segment AC
AB = 4x-6
AC = 2x+10
BC = 4
now since Point B is on line segment AC, therefore
AC = AB + AC
⇒ 2x + 10 = 4x - 6 + 4
⇒ 2x + 10 = 4x - 2
⇒ 2x = 12
⇒ x = 6
Put the value of x in AC, we get
AC = 2(6) + 10
or, AC = 12 + 10
or, AC = 22 units.
Hence, the numerical length of AC is 22 units.

A.155.0
B.151.9
C.150.5
D.141.4
E.158.1
Answer:
The answer is option E.Step-by-step explanation:
The length of a line segment or the distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
J(-4,2) and G(146,52)
The the length of the line segment joining the points is
[tex] |JG| = \sqrt{ ({ - 4 - 146})^{2} + ({2 - 52})^{2} } \\ = \sqrt{ ({ -150})^{2} + ({ -50})^{2} } \\ = \sqrt{22500 + 2500} \\ = \sqrt{25000} \\ = 50 \sqrt{10} \\ = 158.11388[/tex]

The triangle is an isosceles and an obtuse triangle
What Is an Isosceles Triangle?A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.
In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle
The three types of Isosceles Triangles are :
Isosceles acute triangle
Isosceles right triangle
Isosceles obtuse triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of ∠ABC = 120°
So , it is an obtuse triangle with angle > 90°
Now , the measure of sides AB = measure of BC
So , an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base
Therefore , it is an Isosceles obtuse triangle
Hence , the triangle is isosceles

2.4+10m=6.89 what does m equal
Answer:
m = 0.449
Step-by-step explanation:
Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.
PEMDAS is the order of operation & =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition

First, subtract 2.4 from both sides:
2.4 (-2.4) + 10m = 6.89 (-2.4)
10m = 6.89 - 2.4
10m = 4.49
Divide 10 from both sides:
(10m)/10 = (4.49)/10
m = 4.49/10
m = 0.449
0.449 is your answer for m.

A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bicycle? Use any strategy to solve.
Answer:
640 students
Step-by-step explanation:
We are told in the question that 4 out of every 5 students owns a bicycle
This also means , out of every 5 students only 1 does not have bicycle
Then we have a ratio of 4 : 1
This means a fraction of 4/5 students own a bicycle in a school
Based on this result, how many of the 800 students in a school own a bicycle?
This calculated as:
4/5 × 800
= 640 students
Therefore, 640 students out of 800 students own a bicycle
