Answer:

i think it is 3

Step-by-step explanation:

i drawed a circle and put it into sections

then i saw that to get the 40 degree angle i have to divide it for times to make 8 parts

then i did 12 divided by 4 because divide the circle four time

when i did 12/4 i got 3

and if i am correct

thats the answer

Instead of having 1.5 times as many pink flowers as white

elena55 [62]

Answer:

The first row has 4 pink flowers and 2 white flowers

The second row has 6 pink flowers and 3 white flowers

The third row has 8 pink flowers and 4 white flowers.

Step-by-step explanation:

Based on the above question,

Molly has decided to plant a garden with twice as

many pink flowers as white flowers per row.

We can find the number of white flowers in each row by using the principle of ratio to solve this question.

Mathematically, what Molly planted is expressed as:

2 pink flowers : 1 white flower

Therefore for the three rows:

a. The first row is 4 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

4 pink flowers = designated as y

We cross multiply

2× y = 4 × 1

Divide both sides by 2

y = 4 ÷ 2

y = 2 white flowers.

Therefore, the first row that Molly planted 4 pink flowers has 2 white flowers.

b. The second row, Molly planted 6 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

6 pink flowers = designated as z

We cross multiply

2× z = 6 × 1

Divide both sides by 2

z = 6 ÷ 2

z = 3 white flowers.

Therefore, the second row that Molly planted 6 pink flowers has 3 white flowers.

c. The third row , Molly planted 8 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

8 pink flowers = designated as p

We cross multiply

2× p = 4 × 1

Divide both sides by 2

P = 8 ÷ 2

y = 4 white flowers.

Therefore, the third row that Molly planted 8 pink flowers has 4 white flowers.

Therefore, since Molly has decided to plant a garden with twice as

many pink flowers as white flowers per row,

The first row has 4 pink flowers and 2 white flowers

The second row has 6 pink flowers and 3 white flowers

The third row has 8 pink flowers and 4 white flowers.

Please help In which table does y vary directly with x?

grigory [225]

Answer:

Table D

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Verify each case

Table A

For x=1, y=3

Find the value of k

$k=y/x$ -----> $k=3/1=3$

For x=2, y=9

Find the value of k

$k=y/x$ -----> $k=9/2=4.5$

the values of k are different

therefore

The table A not represent a direct variation

Table B

For x=1, y=-5

Find the value of k

$k=y/x$ -----> $k=-5/1=-5$

For x=2, y=5

Find the value of k

$k=y/x$ -----> $k=5/2=2.5$

the values of k are different

therefore

The table B not represent a direct variation

Table C

For x=1, y=-18

Find the value of k

$k=y/x$ -----> $k=-18/1=-18$

For x=2, y=-9

Find the value of k

$k=y/x$ -----> $k=-9/2=-4.5$

the values of k are different

therefore

The table A not represent a direct variation

Table D

For x=1, y=4

Find the value of k

$k=y/x$ -----> $k=4/1=4$

For x=2, y=8

Find the value of k

$k=y/x$ -----> $k=8/2=4$

For x=3, y=12

Find the value of k

$k=y/x$ -----> $k=12/3=4$

All the values of k are equal

therefore

The table D represent a direct variation or proportional relationship

The linear equation is $y=4x$
