How to solve:

We need to create a table for Donovan's height, compare it to Margaret's table, and then choose the appropriate statement. H will represent height, and a will represent age. B and c are constant values, and x is a coefficient to a-c

Simplifying equation

Set up equation                                                 H = 105 + 4.25(a - 5)

Distribute                                                            H = 105 + (4.25a - 21.25)

Age 5

Set up equation                                                 H = 105 + (4.25a - 21.25)

Substitute                                                           H = 105 + [(4.25*5) - 21.25]

Simplify                                                               H = 105 + (21.25 - 21.25)

Simplify                                                               H = 105

Age 6

Set up equation                                                  H = 105 + (4.25a - 21.25)

Substitute                                                            H = 105 + [(4.25*6) - 21.25]

Simplify                                                                H = 105 + (25.5 - 21.25 )

Subtract                                                               H = 105 + 4.25

Solve                                                                    H = 109.25

Age 7

Set up equation                                                  H = 105 + (4.25a - 21.25)

Substitute                                                            H = 105 + [(4.25*7) - 21.25]

Simplify                                                                H = 105 + (29.75 - 21.25)

Subtract                                                               H = 105 + 8.5

Solve                                                                    H = 113.5

Continue for the following ages (8-10)

1. Create a table for both sets of data. Example:

______________________________________________

Age                       |   5   |      6     |    7   |     8     |   9   |     10     |

Mar. height (cm)  | 101  |    105   |  109  |   113    |  117  |    121     |

Don. height (cm) | 105 | 109.25 | 113.5 | 117.75 | 122 | 126. 25 |

______________________________________________

2. Find which statement applies

    2a. Margaret did not grow faster than Donovan

    2b. Donovan did grow faster than Margaret

    2c. Margaret and Donovan did not grow at the same rate

    2d. There is enough data to draw a conclusion

Check:

We came to this conclusion by putting Donovan's data into a chart. We can check by writing an equation for Margaret's height. Then, use that equation with Donovan's to see the difference

Margaret's equation:

H = 4a + 81

Comparison (using ages 8 & 9):

8:

H= 4a + 81       |       H = 105 + (4.25a - 21.25)

H = (4*8) + 81   |       H = 105 + [(4.25*8) - 21.25)

H = 32 + 81      |       H = 105 + 12.75

H = 113             |       H = 117.75

9:

H = 117              |      H = 122

________________________

113 < 117.75

117 < 122

Because the statement still holds true, answer B is correct.

Step-by-step explanation:

Answer:

1. 78 ounces

2. 52 ounces

3. 12 guests

Step-by-step explanation:

1. Consider 6 ounces of dough and 4 ounces of sauce for each person as a set. So 1 set will have 10 ounces. Then, we divide the total ounces, 130 ounces by 10, which will give us 13 sets or people.Then, to find the ounces of dough,just multiply 6 ounces by 13 which will give us 78 ounces.

2. Similar to previous one, just multiply 4 ounces by 13 which will give us 52 ounces or simply minus 78 ounces from 130.

3. We obtained 13 sets(people) from number 1. Minus one (the host, yourself) from 13, we'll get 12.

Answer:

  (a)  18.84 cm

Step-by-step explanation:

The circumference of a circle is given by the formula ...

  C = 2πr . . . . . for radius r

A circle of radius 3 cm will have a circumference of ...

  C = 2(3.14)(3 cm) = 18.84 cm

_____

Additional comment

The area is ...

  A = πr² = 3.14(3 cm)² = 28.26 cm²

The units of area are not cm, but are cm². This question asks for circumference. The shading may be misleading.

Answer:

7 m/s square root 2

Step-by-step explanation:

Answer:

x = -1.5

Step-by-step explanation:

(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)

*I would first change any  minus signs that are outside of the parenthesis to a plus sign. This is optional, not necessary. *

0.5x + 1.2 + (-3.6) + 4.5x = 4.8–0.3x + 10.5x + 0.6

*Now combine like terms on each side. *

5x + (-2.4) = 10.2x + 5.4

*move all Xs on one side.*

-5.2x = 7.8

*Divide both sides by -5.2 to get X by itself."

x = -1.5

Answer: B. perpendicular lines because they intersect at a right angle, making them perpendicular.

Answer:

None of the above

Step-by-step explanation:

Parallel Lines are not shown in this triangle and it is impossible for a triangle to have parallel lines due to its shape. Perpendicular lines are not shown either. Skew lines are only in 3d models and shapes. This is a 2d shape.

Answer :D

x = 52

Question explanation:

1. Add 28 to both sides:

[tex]5x - 28 = 232[/tex]

[tex]5x - 28 + 28 = 232 + 28[/tex]

2. Simplify:

[tex](adding, add again) = 5x =260[/tex]

3. Divide both sides by the same factor

[tex]5x = 260[/tex]

[tex]\frac{5x}{5} = \frac{260}{5}[/tex]

4. Cancel terms that are in both the numerator and denominator.

5. Divide the numbers.

x = 52

Answer:

new answer with estimate= 10 old answer= [tex]9.24[/tex]

Step-by-step explanation:

Use this method percent proportion

[tex]\frac{Percent}{100} = \frac{Part}{Whole}[/tex]  or   [tex]\frac{Percent}{100} = \frac{is}{of}[/tex]

Answer:

12% of 77

[tex]\frac{12}{100} = \frac{x}{77} = \frac{100x}{100} = \frac{924}{100} x = 9.24[/tex]

Steps:

1. Make a proportion with the method percent proportion.
2. After setting up numbers in proportion cross-multiply.

3. Make 100x because we don't know the value of x.

4. After multiplying 12 x 77 you should've gotten 924.

5. After cross-multiplying divide your new proportion.

6. [tex]x= 9.24[/tex]  estimate = 10

now I'm not sure if those number in your question is your new estimate answer but since 9.24 is close to 10 your answer will be 10

Have a great day hoped it helped :)

Answer:

D. None.

Step-by-step explanation:

Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.

Answer:

1.  36

2.  2000

Step-by-step explanation:

Step-by-step explanation:

903.6 ÷ 25.1 = 36 (exact answer).

900 ÷ 30 = 30 (estimated). As 903.6 near to 900 and not to 1000, and 25.1 near to 30 and not to 25 the equation is 900 ÷ 30 = 30.

760.38 ÷ 0.38 = 2001 (exact answer).

In the estimated answer Im not so sure about it so I leave you four choices.

1. 800 ÷ 0.40 = 2000 (rounded to the nearest ten)

2. 800 ÷ 0.00 = Infinity (0.38 close to a whole)

3. 800 ÷ 1 = 800 (0.38 not close to a whole)

4. 800 ÷ 40 = 20 (possibly the wrong answer not even close to 0.38)

Answer:

The explanation on how to do them is down below. If you have anymore questions pls feel free to ask

Step-by-step explanation:

So for number one you just need to state the sentence under the lines back wards but starting Lines m and n......

For number two name two angles that are inside the parallel lines and for three the opposite name two that are basically verticle outside of the parallel lines.

For number four they are across from each so they are verticle and since they are verticle they are concurrent so the m of 2 is 125.

In number 5,4 and 7 are corresponding so the are equal.

In number 6 the angles are alternate interior so they are congruent.

In number 7, the angles are corresponding so they are congruent.

In number 8, the angles are alternate exterior so they are congruent.

In number 9, the angles are are verticle so the are congruent.

In number 10, the answer is supplementary because on the top and bottom they add up to 180 degrees. And it part b 2 and 3 are adjacent and supplementary, so you subtract 119 from 180 and you get 61.

Answer: ~3.8 mph (see below)

What we know:

How to solve:

We need to find what number when multiplied with 1045, will equal 3600. The unknown will be a variable x, and the seconds will be represented with s. Then, we need to multiply this number with the value of the miles (m) to find how many miles are traveled in that hour (h).

Finding X (in seconds)

Set up equation                                                       H = sx

Substitute                                                           3600 = 1045x

Divide                                                                 /1045   /1045

Solution                                                 3.44497608 = x

Finding Miles

Set up equation                                                 mph = x(m/s)

Substitute                                                           mph = 3.44497608(1.1/1045)

Simplify                                                               mph = ~3.79/3600

Convert                                                               mph = ~3.8 miles per hour
