If the endpoints of AB have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of AB?

Answers

The midpoint of a line segment given the coordinates of the endpoints may be obtained by getting the average of the two abscissas and ordinates. With the given above, the average of the abscissas is 4 and that of the ordinates is 3. Thus, the midpoint is at (4, 3).

Answer:

The cross section will be an isosceles triangle

Step-by-step explanation:

The image of the inquiry in the joined figure N 1

we realize that

On the off chance that a plane goes through the pivot of revolution of the cone, at that point the resultant cross-area will be a triangle with one vertex as the vertex of the cone and the different sides of the triangle through the vertex A will be equivalent.

Where the base of the triangle will be equivalent to the breadth of the round base of cone and the two compatible sides of triangle will be equivalent to the inclination tallness of the cone

hence

The cross segment will be an isosceles triangle

Rebecca sold 11 more magazine subscriptions than Chad.Laura sold 4 more than Rebecca.Laura sold 45 magazine subscriptions.How many magazine subscriptions did Chad sell?

Answers

Since Laura sold 4 more than Rebecca, you subtract 4 from 45 which is 41, and Rebecca sold 11 more than Chad, you subtract 11 from 41 which is 30.
Laura sold 45 magazine.
Rebecca sold 41 magazine.
Chad sold 30 magzine.

$45-4 = 41 \ (Rebecca) \n\ 41-11 = 30 \ (Chad)$

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50a + 3.75b = 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

Answers

Given:
b = 82
\
Asked:
a = number of adult tickets sold = ?

Solution:
10.50(a) + 3.47(82) = 2071.50

solving for a:

a= [2071.5-3.47(82)]/10.50

a=168

FINAL ANSWER: There were 168 adult tickets sold.

Answer:

The correct answer would be , a = 168 tickets were sold

Step-by-step explanation:

Cost of adults ticket = $10.5

Cost of Students Ticket = %3.75

Sales Totals for opening night = $2071.5

Equation would be

10.5a + 3.75b = 2071.5

If 82 students attended the the play at that night, it means the value of b would be 82. Thus substituting the value in the above equation, we can find the value of a, which means how many adult tickets were sold.

10.5a + 3.75(82) = 2071.5

10.5a + 307.5 = 2071.5

10.5a = 2071.5-307.5

10.5a = 1764

a= 168 tickets were sold.
