If the ratio of the purple flowers to black flowers is 4 to 8 and there are a total of 108 flowers how many of the flowers are purple

Answers

Answer 1

Answer: Ok let's see.

The way to tackle this, is to first add up the ratio's.

So 4+8 = 12. Now this 12 is important as this is total number of shares (bunches) we need to allocate to 2 different flower colours.

Before we can know how much flowers = 4 and 8 bunches. We first need to work out how many flowers = 1 bunch.

It's simple.

108 (total number of flowers) ÷ 12 (bunches of flowers) = 9 flowers per bunch.

So if 1 bunch = 9 flowers.

4 : 8

= (4 bunches x 9 flowers) : (8 bunches x 9 flowers)

Which leads to...

36 purple : 72 black

Answer 2

Answer: Purple flowers: black flowers = 4:8 = 108

4 + 8 = 12

108 / 12 = 9.

9 x 4 = 36.

36 of the flowers are purple.

I need help with part a and park b pleasee!

Answers

Part A: First plot the points. Then you have to find the midpoint of AB.

Midpoint Formula:(x1+x2)/2,(y1+y2)/2

Answer: (-1,-1)

Part B: We know that the midpoint is (-1,-1). C is (2,7) and D is (x,y)

So redo the midpoint formula with both C and D.

(2+x)/2=-1

2 + x =-2; x=-4

(7+y)/2=-1

7 + y=-2; y=-9

Hope this helps!

Formula for the coordinates of the midpoint of the AB sector:

$A(x_A,\ y_A);\ B(x_B;\ y_B)\n\nM_(AB)\left((x_A+x_B)/(2);\ (y_A+y_B)/(2)\right)$

$A(-8,\ 7),\ B(6,\ -9)\n\nM\left((-8+6)/(2);\ (7+(-9))/(2)\right)\to M\left((-2)/(2);\ (-2)/(2)\right)\to M(-1;\ -1)$

Answer: The picture 1. M(-1, -1).

$C(2,\ 7),\ M(-1,\ -1)\n\n(2+x)/(2)=-1\ ;\ (7+y)/(2)=-1\ \ \ \ |\cdot2\n\n2+x=-2\ ;\ 7+y=-2\n\nx=-4\ ;\ y=-9\n\nD(-4;\ -9)$

Answer: The picture 2. D(-4, -9).
