Answer:

17166 m/days

Step-by-step explanation:

1 mile = 1609.34 m

4 miles = 1609.34×4

= 6437.38m

1 hour = 0.0416667

9 hours = 9 × 0.0416667

= 0.375 days

Speed= (6437.38/0.375) m/days

= 17166.34667 m/days

= 17166 m/ days ( nearest whole number)

Answer:

the answer is A hope it helps: )

Answer:

A

Step-by-step explanation:

I had this question on a practice test, it's correct.

∠CAB and the angle above it whose measure is 84° are vertically opposite angles , which means their measure will be equal .

By the definition of vertically opposite angle, Measure of an angle CAB is, 84°.

Parallel lines are those lines that are equidistance from each other and never intersect each other.

We know that;

The vertically opposite angles are equal to each other.

Here, ∠CAB and the angle above it whose measure is 84° are vertically opposite angles.

Hence, Measure of ∠CAB = 84°

Answer: Number 3; $1250

Number 4; Salesperson A ($7428.30)

Number 5; 18%

Number 6; Rent 780, Food 900, Medical 450, Clothes 300, Miscellaneous 570.

Step-by-step explanation: (No 3) The principal amount is 5000, the rate is 5% (0.05) and the time in years is 5. The formula for calculating simple interest is as follows;

I = P x R x T

I = 5000 x 0.05 x 5

I = 1250

Therefore Joanna will pay $1,250 as interest

(No 4) The amount made by both salespersons is shown as follows;

A = 11% x 67530

A = 0.11 x 67530

A = 7,428.30

B= 8% x 85740

B = 0.08 x 85740

B = 6,859.20

Therefore from the calculations above, salesperson A made more commission and the amount made is $7,428.30

(5) John's earning is 38000 and he paid 6840 for entertainment. The percentage paid for entertainment therefore is as follows;

Percent paid = (entertainment/total income) x 100

Percent paid= (6840/38000) x 100

Percent paid = 684000/38000

Percent paid = 18

Therefore he paid 18% for entertainment

(6) Nora makes a total of 3000 a month broken down as follows;

Rent = (26/100) x 3000

Rent = 0.26 x 3000

Rent = 780

Food = (30/100) x 3000

Food = 0.30 x 3000

Food = 900

Medical = (15/100) x 3000

Medical = 0.15 x 3000

Medical = 450

Clothes = (10/100) x 300

Clothes = 0.10 x 3000

Clothes = 300

Miscellaneous = (19/100) x 3000

Miscellaneous = 0.19 x 3000

Miscellaneous = 570

Answer: Number 3; $1250

Number 4; Salesperson A ($7428.30)

Answer:

We calculate the amount of gas used per km and multiply it by 286

Step-by-step explanation:

If we drive for 260km and use 12 litres of gas that means that we use

[tex]\frac{12}{260}[/tex] litres per km.

Now we multiply it by 286:

[tex]\frac{12}{260} *286 = \frac{858}{65} = 13.2[/tex]

So, the answer is 13.2 litres.

Answer:

A and D.

Step-by-step explanation:

A sequence is a set of the objects or numbers in a specific order. It is a function whose domain is a set of natural numbers or non-negative integers i.e. {1, 2, 3,..}

(A)

"An arithmetic sequence is a linear function whose domain is restricted to the set of non-negative integers."

The general form an arithmetic sequence is:

[tex]a_{n}=a_{1}+(n-1)d[/tex]

The function is linear. The sequence consists of either numbers that are increasing or decreasing based on the value of d, the common difference.

So, the statement provided is True.

(D)

"A geometric sequence is an exponential function whose domain is restricted to the set of non-negative integers."

The general form an geometric sequence is:

[tex]a_{n}=a_{1}\cdot r^{n-1}[/tex]

The function is exponential. The sequence consists of either numbers that are exponentially increasing or decreasing by the factor r, the common ratio.

So, the statement provided is True.

Answer:

[tex]m=-\frac{4}{3}[/tex]

Step-by-step explanation:

Formula

[tex]m=\frac{rise}{run}=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Solve

[tex]m=\frac{10+6}{-14+5}=\frac{16}{-9}=-\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

A=(-5, -6) = (x1 , y1)

B= (-14, 10)= (x2 , y2)

slope= y2 - y1/ x2- x1

=10+6/ -14+5

= 16/ -9

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

Work Shown:

P(E or F) = P(E) + P(F) - P(E and F)

0.55 = 0.40 + P(F) - 0.20

0.55 = P(F) + 0.20

P(F) + 0.20 = 0.55

P(F) = 0.55 - 0.20

P(F) = 0.35

---------

note: Sometimes you may see the formula as

P(E and F) = P(E) + P(F) - P(E or F)

but it's an equivalent form to the first equation above.

Answer:

14 depth per minute

Step-by-step explanation:

84/6 = 14

Answer:

[tex]m\angle1 =47^o[/tex]

[tex]m\angle2 =119^o[/tex]

[tex]m\angle ABC =97^o[/tex]

[tex]m \angle FED = 62^o[/tex]

Step-by-step explanation:

angle 1 and the angle 133 degrees are supplementary angles, then added should give 180 degrees.

angle1 + 133 = 180   then angle1 = 180-133 = 47 degrees

[tex]m\angle1 = 180^o - 133^o=47^o[/tex]

Angle 2 is of the same measure as the angle marked as 119 degrees since they are what is called "corresponding angles between parallel lines."

Angle ABC plus angle that measures 83 degrees should add to 180 since their sum gives a straight line, then:

ABC + 83 = 180

ABC = 180 - 83 = 97 degrees

Last image:

The two angles with algebraic denomination should be equal because they are alternate internal angles, Then this equality can be written as:

8 x - 34 = 5 x + 2

solve for x by subtracting 5 x from both sides:

3 x - 34 = 2

add 34 to both sides:

3 x = 2 + 34

3 x = 36

x = 36/3

x = 12

and now knowing x we can find angle DEF

DEF = 5 x + 2 = 5 (12) + 2 = 60 + 2 = 62 degrees

Answer: A 83

Step-by-step explanation:

Add 46 to 51 then subtract from 180 to get the correct answer(83)

Answer:

mode

Step-by-step explanation:

in statistics, the mode is the most commonly observed value in a set.

Answer:

Mode

Step-by-step explanation:

Mode is the value that is shown most frequently in a set.

Answer:

First part:

Set h(t) = 73 and solve for t.

-16t2 + 64t + 16 = 73

-16t2 + 64t - 57 = 0

Solve this quadratic equation for t.  You should get 2 positive solutions.  The lower value is the time to reach 73 on the way up, and the higher value is the time to reach 73 again, on the way down.

Second part:

Set h(t) = 0 and solve the resulting quadratic equation for t.  You should get a negative solution (which you can discard), and a positive solution.  The latter is your answer.

STATEMENT ====> REASONS

1. m<AOB = 180° ==> 1. Definition of straight angle

2. m<AOF + m<FOG + m<GOB = m<AOB ==> 2. Angle Addition Postulate

3. (5x - 15)° + 90° + 2x = 180° ==> 3. Substitution

4. Solve as algebra to get x

5x - 15 + 90 + 2x = 180

Collect like terms

5x + 2x - 15 + 90 = 180

7x + 75 = 180

Subtract 75 from both sides

7x + 75 - 75= 180 - 75

7x = 105

Divide both sides by 7

7x/7 = 105/7

x = 15 ===> 4. Algebra

Answer:

The side lengths of the image after the dilation = 13.5 cm and 20.25cm

Step-by-step explanation:

A rectangle has side lengths 6 cm and 9 cm. What would the side lengths of the image be after a dilation of 2.25? Explain your reasoning.

Dilation can also be referred to as scale factor

6cm × 2.25 = 13.5 cm

9 cm × 2.25 = 20.25 cm

The side lengths of the image after the dilation = 13.5 cm and 20.25cm
