Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 150 adults and 280 children will a

ttend. Let x represent the cost of an adult ticket and y represent the cost of a child ticket. If the goal is to raise $1310, which of the given equations may be used to represent this situation?
280x + 150y =1310

150x + 280y =1310

430x =1310

150x =1310 + 280y

The coordinates of the endpoints of directed line sergeant ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2 then the coordinates of
cestrela7 [59]

The correct answer is A) (1,-5)

Further explanation:

Given points are:

A(-8,7)=(x1,y1)

C(7,13)=(x2,y2)

IT is also given that

AB:BC=3:2

Which means that B divides the line segment in 3:2

Here,

m=3

n=2

To find the coordinates of B

x_B=\frac{mx_2+nx_1}{m+n}\\ = \frac{(3)(7)+(2)(-8)}{3+2}\\=\frac{21-16}{5}\\=\frac{5}{5}\\=1\\y_B=\frac{my_2+ny_1}{m+n}\\=\frac{(3)(-13)+(2)(7)}{3+2}\\=\frac{-39+14}{5}\\=\frac{-25}{5}\\=-5

The coordinates of point B are (1,-5)

The correct answer is A) (1,-5)

Can someone explain how to do this and add the formula please
lisabon 2012 [21]

Answer:

5 is 35 and 6 is 50

Step-by-step explanation:

To solve 5, you need to know how many degrees is the line, which is 180 because lines are 180 degrees. You then subtract 110 from 180 which equals to 70. What you have left now is 2k. A number times 2 will equal to 70, so k=35.

For 6, if you ever see two lines intersecting each other, it means that it is 360 degrees. We already have one angle, which is 120. The other angle is d+70 degrees, and any angle that is reflecting the other angle will have the same value. So, d equals 50

Can someone please help me on this question? I am very confused!
n200080 [17]

Here we are give the value for π and Diameter of the circle fence

π=3.14

Diameter = 16

Radius = Diameter/2

2πr = 2(3.14)(8)

Circumference = 50.27

Now to fine the square fence length so we do 16*4 = 64

64-50.27 = 13.73 in

Therefore, the square fence is 13.73 inches longer than the circle fence
