20 POINTS!! (please Help Quickk)15 Dance Tickets Were Sold In One Half Hour. If This Rate Continues,

Answers

Answer 1

First, you would divided 270 by 15

270 ÷ 15 = 18

Then, you would divide 18 by 2 because it only takes half an hour to sell 15.

18÷2 = 9

Therefore, it would take 9 hours!

-----

Another Way!

First, multiply 15 by 2 because it only takes half an hour to sell 15.

15×2 = 30

Then, divide 270 by 30!

270÷30 = 9

Therefore, it would take 9 hours!

solve for p 9p - 3p 05 = 19

Answers

Answer:

p = 4

Step-by-step explanation:

9p - 3p - 5 = 19

First you subtract like terms which gives you

6p - 5 = 19

Then you move the constant to the right and change its sign which gives you

6p= 19 + 5

Then calculate your answer which gives you

6p=24

Then divide both sides by 6 which gives you

Determine if the linear equations are parallel, perpendicular, or neither.

y = - 2x, 2y = x, 4y = 2x + 4

a
perpendicular
b
neither
c

Answers

Answer:

C. Neither

Step-by-step explanation:

The first equation is

This equation is already in the slope-intercept form;

The slope of this equation is 2.

The second equation is .

This equation is also already in the slope-intercept form.

The slope of this equation is .

Since the two slopes are not the same, the two lines are not parallel.

If these two lines are perpendicular, then the product of their slopes is -1.

But which is not equal to -1.

Therefore the two lines are also not perpendicular.

The correct choice is C.

Answer:

I’m pretty sure it’s Triangle ABC is congruent to Triangle DEF.

Step-by-step explanation:

If you rotate Triangle DEF to where the 90 degree angle is on the bottom right, you can the compare the two triangles. You can divide 300/25, 240/20, and 180/15. They all result in 12 meaning they are congruent and similar in that way. (I’m only 90% this is right btw)

Of the seeds Quincey planted in his tomato garden, 75% grew into mature plants. If Quincey has 39 tomato plants in his garden, how many seeds did he plant?

PLEASE HELP WORTH 70 POINTS

Answers

Answer:

52 seeds.

Step-by-step explanation:

So, 3/4 of his plants have grown. SO, 3/4 = 39 plants, and if we divide by 3, we get 1/4 of the plants are 13 plants. SO, if we want to find 4/4, we can multiply 13*4=52 seeds.

Quincey planted 52 seeds in total.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

75% grew into mature plants.

If Quincey has 39 tomato plants in his garden.

let x number of seed he planted.

So, 75% of x= 39

75x/100= 39

75x = 3900

x = 52

Hence, He planted 52 seeds.
