9. Andrew was measuring the height of the tree in his yard. Four years after it was planted, the tree was 11 feet tall. Twelve years after the tree was planted, it was 21 feet tall. Assuming the tree was growing at a constant rate, create the equation that models that growth of the tree over time. Show or explain your reasoning. (HINT: Use the two points to find the slope and use point-slope form to create an equation.)

Answer:

2/5 gallons

Step-by-step explanation:

If it takes 2 gallons of paint to paint 5 walls, then the amount of gallons used per wall can be calculated by comparison

[tex]5 walls = 2 gallons \\ 1 \: wall = x \: gallons \\ by \: cross \: multiplication \\ 5 \times x = 2 \times 1 \\ 5x = 2 \\ x = \frac{2}{5} [/tex]

Hence, 2/5 gallons of paint is used per wall.

Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000  x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

D) 27

Step-by-step explanation:

4 + 2 = 6 (pets)

For each pet he spends $4.50, so:

6 × 4.50 =

6 × 4 = 24 +

6 × 0.5 =

6/2 = 3

24 + 3 = 27

x > -1

Step-by-step explanation:

5-2x < 7

5 - 2x - 5 < 7 - 5

-2 x < 2

(-1) (-1)

2x > -2 (divide both sides by 2)

*answer*

Answer:

-1<x

Step-by-step explanation:

5-2x<7

Subtract 5 from both sides:

-2x<7-5

-2x<2

Divide by 2:

-x<1

Switch sides (add x, subtract 1):

Answer:

D

Step-by-step explanation:

Answer:

1) Not Similar. 2/6 does not equal 6\12

2) Yes. 5/3 = 15/9

3)Yes. 10/30=8/24

4) Not Similar. 13/16 does not equal 16/21.

5) Not Similar. 28/48 and 42/36 do not reduce to the same value.

6)No. The angles are not the same.

Step-by-step explanation:

Ask yourself, is it proportional? Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

In other words, ifthe corresponding sides reduce down to the same value, they are similar.

The frequency for 2 to 7 is 3

The frequency for 8 to 13 is 4

The frequency for 14 to 19 is 2

The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.

We need to complete the grouped frequency distribution for the data.

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 2 to 7 the frequency is 3.

For intervals 8 to 13 the frequency is 4.

For intervals 14 to 19 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Answer: the third option

Step-by-step explanation:

The third option means less than or equal to, so if 1/4 of a number is no more than 2/3, it is less than or equal to 2/3

The correct symbol for the inequality is ≤

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given that, Michaela needs to represent this statement as an inequality.

One-fourth of a number is no more than two-thirds.

So, in the given options, the third option means less than or equal to,

so if 1/4 of a number is no more than 2/3, it is less than or equal to 2/3

Hence, the inequality will be =

x/4 ≤ 2/3

Hence, the correct symbol for the inequality is ≤
