What Is The Approximate Average Rate Ofchange For The Height Of The Plant, Measured Incentimeters Per

Answers

Answer 1

Answer:

Average change in height of the plant is 0.5 cm per day.

Step-by-step explanation:

Height of the plant on day 20 = 40 cm

Height of the plant on day 40 = 50 cm

Change in height = 50 - 40 = 10 cm

Number of days between day 20 and day 40 = 20

Average change in height of the plant = [tex]\frac{\text{Change in height of the plant}}{\text{Duration}}[/tex]

                                                                = [tex]\frac{10}{20}[/tex]

                                                                = 0.5 cm per day

Therefore, average change in height of the plant is 0.5 cm per day.

What is the equation in slope – intercept form? 7x + 2y = 14

Answers

Answer:

y = - [tex]\frac{7}{2}[/tex] x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

7x + 2y = 14 ( subtract 7x from both sides )

2y = - 7x + 14 ( divide all 3 terms by 2 )

y = - [tex]\frac{7}{2}[/tex] x + 7 ← in slope- intercept form

Answer:

SU = 22

Step-by-step explanation:

SU = ST + TU

Also , SU = 2y - 4 ; ST = y ; TU = 18

So,

[tex]2y - 4 = y + 18[/tex]

[tex] = > 2y - y = 18 + 4[/tex]

crazy son Calvin runs around the castle and opens all the doors. Then he runs around the castle and
closes every other door (2, 4, 6, 8, ... 100). Then he runs around the castle and when he comes to
every third door (3,6,9,12,...99) if it is open he closes it and if it is closed he opens it. He then does
the same for every 4th door, then every 5th door and then every 6th door, and so on until then does
it for every 100th door. At the end of this exhausting run clearly door 1 is open, but what other door
are also open? (hint: Grappling would suggest you try using a smaller number like 20 doors and see

Describe in words the translation of X represented by the translation rule T ...?

Answers

Answer: B. 4 units to the right, 5 units down

The vector notation <4, -5> is the same as writing [tex](x,y) \to (x+4, y-5)[/tex] which in my opinion is more descriptive in saying "4 units to the right, 5 units down"

We shift 4 units to the right because of the x+4. Whatever x is, add 4 to it getting x+4. So for instance x = 10 leads to x+4 = 10+4 = 14.

The y-5 is why we shift 5 units down. Eg: y = 37 leads to y-5 = 37-5 = 32.

Hope This Helps :)

Answer:

The answer is 11.

Step-by-step explanation:

Use PEMDAS

P - Parenthesis

E - Exponents

M - Mulitiplication

D - Divide

A - Add

S - Subtract

So, with that you learn that you solve whatever is in the parenthesis first.

(9 - 3) = 6

Now, divide 20 by 4 which equals 5.

So now the problem is now 6 + 5 which equals 11.

The answer is 11.

25(b+3)=11(b-7) using distributive property when solving equations.

Answers

Answer:

b = -76/7

Step-by-step explanation:

Step 1: Write equation

25(b + 3) = 11(b - 7)

Step 2: Solve for b

Distribute: 25b + 75 = 11b - 77

Subtract 11b on both sides: 14b + 75 = -77

Subtract 75 on both sides: 14b = -152

Divide both sides by 14: b = -76/7

Step 3: Check

Plug in b to verify it's a solution.

25(-76/7 + 3) = 11(-76/7 - 7)

25(-55/7) = 11(-125/7)

-1375/7 = -1375/7

Answer:

b= -10.85

Step-by-step explanation:

25(b+3)=11(b-7)

25b+75=11b-77

      +77       +77

25b+152=11b

-25b        -25b

      152=-14b

      -14   -14

-10.8571=b

Answer:

Interesting question.

112/12 = 28/3

so 3/28 * 112 = 12

so we multiply 3/28 * 312

936/28

Simplifying we get 33 3/7

[tex]33 \frac{3}{7}[/tex] is the answer.

Answer:  2 & 11/14 cups of flour

This is a mixed number with 2 as the whole part and 11/14 as the fractional part.

You may need to drop the ampersand sign and simply say 2 11/14

==============================================

Work Shown:

112 dozen muffins = 312 cups of flour

112/112 dozen muffins = 312/112 cups of flour

1 dozen muffins = 312/112 cups of flour

1 dozen muffins = (39*8)/(14*8) cups of flour

1 dozen muffins = 39/14 cups of flour

1 dozen muffins = (28+11)/14 cups of flour

1 dozen muffins = (28/14+11/14) cups of flour

1 dozen muffins = (2+11/14) cups of flour

1 dozen muffins = 2 & 11/14 cups of flour
