Which statement is true about the relationship between the amount of plant food remaining and the number of days? Can you help me with this problem

Answer:  this is in a fraction: X = 16/5, decimal form: x = 3.2, and in a mix number: x = 3 1/5

Step-by-step explanation:

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer: 150% increase

Step-by-step explanation:

percent of increase: new/old × 100%-100%

--------------

new/this month: 20 puppies

old/last month: 8 puppies

 new/old×100%-100%

=20/8×100%-100%

=2.5×100%-100%

=250% -100%

=150% increase

a century = 100 years.

3/4 x 100 years = 75 years.

2/5 x 100 years = 40 years.

Answer:

the thousandths equils 2

Step-by-step explanation:

yuh

Answer:

  9007 thousandths = 9.007

Step-by-step explanation:

A unit is 1000 thousandths, so 9 ones is 9000 thousandths.

You have ...

  0.002 + 9.005 = 9.007

  2 thousandths + 9 ones 5 thousandths = 9007 thousandths = 9.007

Answer:

y = 10

Step-by-step explanation:

4/5 y = 8

4/5 y * 5/4 = 8 * 5/4           multiply by reciprocal

y = 10

Answer: y=10

Step-by-step explanation:

times each side by 5 so you're left with 4y=40

divide wach by 4 and then you got the answer

Answer:

Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)

Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's

Line 2 and Line 3: Neither -- different slopes

Step-by-step explanation:

Lines are parallel if they have the same slope but different y-intercept.

Lines are perpendicular if the slopes are negative reciprocals.

Answer:

number of hours worked equation

The observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Observed amount:

At x = 7.9, y = $33.50

At x = 25.00, y = $25.00

We have a line of best fit:

y=0.3x+24.00

At x = 7.9

Predicated amount:

y = $26.37

At x = 12.1

Predicated amount:

y = $27.63

Residual (when x = 7.9)  = $33.50 - $26.37 = $7.13

Residual (when x = 12.1) = $25.00 -  $27.63 = -$2.63

Thus, the observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

Answer:

4:3

Step-by-step explanation:

divide 8 by 2 and 6 by 2

8/2:6/2

4:3

Hi there!

Answer:

4:3

Step-by-step explanation:

Here is how we simplify a ratio:

1.Find the greatest common factor in both of the numbers

2.Divide both of the numbers by that factor.

3. And than your done solving the problem!

*******************************************************************

You have to divide both numbers by 2 because the GCF of 8 and 6 is 2

Remember; GCF means Greatest Common Factor...

8/2=4

6/2=3

Since we got 4 and 3...

The answer would be 4:3

So, 8:6 would equal to 4:3

Also if you want to simplify you have to divide and make it the smallest number you can!

If we simplify 8:6 it will be 4:3 but we can’t simplify 4:3 so that will be the answer.

(Note; Half of 8 is 4 and half of 6 is 3 so we know that’s correct, it’s also a way you can check your work)

~Have a great day!~

Answer:

deviation = -95.50147493     mean = 61

Step-by-step explanation:

54% wet there brushes first

suppose 68% wet there brushes what is the mean

mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this

54 + 68 = 122

we added to numbers so well divide by 2

122 divided by 2 or 122/2 is equal to 61

61 is our mean

standard deviation : this is were you take the known average 1356 adults and subtract the mean

1356- 61 = 1295 then divide by 1356 and times by 100

if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493

Answer:

D. 1,000 cm^3

Step-by-step explanation:

Surface area of a cube is calculated by multiplying the square value of the edge by 6 which is shown as 6 × a^2

6 × a^2 = 600

a^2 = 100

a = 10

The volume of a cube is calculated by multiplying edge with itself three times which is shown as a^3

10^3 = 1000

Answer:

D

Step-by-step explanation:

10×10 on each side of the cube= 100. 6 sides = 600.

10×10×10= 1000

Let's assume the number as x

→ ⅔rd of x =( ⅔)x

Now ⅔ of x is greater than ⅓ of 5 .

[tex] \sf{ \implies \: \dfrac{1}{3} \times 5 = \dfrac{5}{3} } [/tex]

[tex]\sf{ \implies \: \dfrac{2}{3} \times x > \dfrac{5}{3} } [/tex]

[tex]\sf{ \implies \: x > \dfrac{5}{3} \times \dfrac{3}{2} }[/tex]

[tex]\sf{ \implies \: x > \dfrac{5}{2} }[/tex]

So number will be greater than 5/2 .

Answer:

answer is c

Step-by-step explanation:

Answer: Let length = 2x + 3

Let width = x

Area = 54 ft2

length × width = Area

x(2x + 3) = 54

2x2 + 3x = 54

2x2 + 3x - 54 = 0

(2x - 9)(x + 6) = 0

x = 9/2 and x = -6

x = 4.5 and x = -6

We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:

width = 4.5 ft

length = 2(4.5) + 3 = 9 + 3 = 12 ft

Answer:

Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

The vertex of a parabola is the point at the top or bottom of the parabola.

'h' is -6, the first coordinate in the vertex.

'k' is -4, the second coordinate in the vertex.

'x' is -2, the first coordinate in the other point.

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer:

9, 1, 9, 1

2, 8, 2, 8

3, 7, 3, 7

6, 4, 6, 4

Step-by-step explanation:

you would have to have the numbers repeat so it works, for instance, you could do 9,1,9,1 as the first row then 2,8,2,8 as the second row and for the third row you could do 3,7,3,7 and for the fourth row you could do 6,4,6,4 so both the columns and rows add to 20
