Answer:
1kg of onion is $1.5
Step-by-step explanation:
He paid $10 and got $1.50 back, meaning that the total price for the 2kg and 3kg of the potato and onion is:
10 - 1.5 = $8.50
Now, equating the prices of the two (take x as the cost of the potato per kg and take y as the cost of the onion per kg):
x -0.5 = y
x - y = 0.5 ---- Eq 1
Equating the total costs:
2x + 3y = 8.5 ---- Eq 2
Multiplying Eq 1 by 2:
2x - 2y = 1 ---- Eq 1'
Subtracting Eq 2 from Eq 1':
2x - 2x +3y - (-2y) = 8.5 - 1
5y = 7.5
y = 1.5
Substituting this into the first equation:
x - 1.5 = 0.5
x = 2
Hence,
the cost of the Potato is $2, and
the cost of the Onion per kg is $1.5

write and equation of a parabola with the vertex of (0,3) and the focus of (-8,3)
Answer:
(y-3)²= -32x
Step-by-step explanation:
1) the required equation has a form: (y-y₀)²=-2p(x-x₀), where (x₀;y₀) - vertex (0;3), p - parameter of the given parabola;
x₀=0; y₀=3.
2) according to the conditiion F(-8;3)=F(x₀+p/2; y₀), it means (x₀+p/2; y₀)=(p/2;3), then p/2= -8; ⇒ p= -16.
3) finally, p= -16; x₀=0; y₀=3, then it is possible to make up the required equation:
(y-3)²= -32x.

What is the sum of the first 7 terms for the geometric sequence with first term 3, seventh term 46,875, and common ratio 5
A. 35,154
B. 58,593
C. 19,531
D. 11,718
The sum of the given geometric sequence with first term 3 and seventh term 46875 is 136717 so none of the given options are correct.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
Given that,
First term (a) = 7
Common ratio r = 5
Seventh term = 46875
The sum of the first n term in GP is given as,
[tex]S_{n} = a(r^n-1)/(r-1)\\[/tex]
Sum of first seventh term,
S₇ = 7(5⁷ - 1)/(5-1)
S₇ = 136717
Hence "The sum of the given geometric sequence with first term 3 and seventh term 46875 is 136717 ".

Step-by-step explanation:
The first part of solving the area is multiplying the rectangle. So you do 15*18 which is 270. Then to solve a triangle you make it a square/rectangle. So it would be 8*15 which is 120. Because the length is the length of the rectangle and the width is shown on top. Then because it’s a rectangle not a triangle you divide by 2 because you were adding half to it when you were making it a rectangle. So it’s 120/2 which is 60. And 270+60 is 330. So the area is 330. To get the perimeter you add all the sides together. And because one of the sides is not added but half of the bottom line is the same length as the top so it would be 18+ the 8 on the top which is 26. So 15+18+17+26 is 76. So the perimeter is 76
So the answer is the bottom one. P=76 and A=330
Need help on #9 and #10 please ASAP. Was busy with a family emergency and missed my class on this.
Answer:
#9
given, angle BOD = 95 degree
and angle COD = 35 degree
assume that, angle BOC = x degree
so, angle BOC + angle COD = angle BOD
or, x + 35 degree = 95 degree
so, x = 95 degree - 35 degree = 60 degree
so, angle BOC = 60 degree
#10
given, angle AOC = right angle = 90 degree
and angle AOB = 30 degree
assume that, angle BOC = y degree
so, angle AOB + angle BOC = angle AOC
or, 30 degree + y = 90 degree
so, y = 90 degree - 30 degree = 60 degree
so, angle BOC = 60 degree

Step-by-step explanation:
solve for y
[tex]3y - 7 = 2x[/tex]
isolate the y variable to one side
let's first add 7 to both sides of the equation
[tex]3y - 7 + 7 = 2x + 7[/tex]
sevens on the left side of the equation cancel so we get
[tex]3y = 2x + 7[/tex]
Now let's divide everything in the equation by 3 to further isolate the y variable
[tex] \frac{3y}{3} = \frac{2x}{3} + \frac{7}{3} [/tex]
The threes on the left hand side of the equation cancel
[tex] y = \frac{2}{3}x + \frac{7}{3} [/tex]
The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c.
The given statement "The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c" is absolutely correct.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
For example
Perimeter of square = side + side + side + side
The perimeter of the circle = πd where d is the dia of the circle.
Given a triangle with sides a,b and c
The perimeter of triangle is = a + b+ c
So,
The perimeter of the triangle is the sum of all sides.
