Answer:

She spends:

2980.83 hours reading in a year,

3406.67 hours listening to music in a year,

and 3650 hours listening to podcasts in a year.

Step-by-step explanation:

Let's multiply each activity she does by 14 and take it to a year:

-Reading

[tex] R = 14*35 \frac{min}{d} = 490 \frac{min}{d}*\frac{365 d}{1 y}*\frac{1 h}{60 min} = 2980.83 \frac{h}{y} [/tex]

She spends 2980.83 hours reading in a year.

-Listenign to music:

[tex] M = 14*40 \frac{min}{d} = 560 \frac{min}{d}*\frac{365 d}{1 y}*\frac{1 h}{60 min} = 3406.67 \frac{h}{y} [/tex]  

She spends 3406.67 hours listening to music in a year.

-Listenign to podcasts:

[tex] P = 14*1.25*4 \frac{h}{w} = 70 \frac{h}{w}*\frac{1 w}{7 d}*\frac{365 d}{1 y} = 3650 \frac{h}{y} [/tex]

She spends 3650 hours listening to podcasts in a year.

I hope it helps you!  

Answer:

option B is correct-$1.45+$0.55× ≤ $35.

Step-by-step explanation:

Total cost equals the $1.45, plus $0.55 per mile. She can only spend $35 or less

In math language:

35≤1.45+.55x

33.55≤.55x

61≤x

So, Ariel can go 61 miles or less for $35

Hope u like it ♥️

The inequality is  $1.45 + $0.55x ≤ $35

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size

Given:

Total cost equals the $1.45, plus $0.55 per mile.

She can only spend $35 or less

$1.45 + $0.55x ≤ $35

0.55x≤ $35-1.45

0.55x≤33.55

x≤ 61

Hence, Ariel can go 61 miles or less for $35.

Answer:

x = 6, AM = 22

Step-by-step explanation:

Since A is the midpoint of RM, then RA = AM = 3x + 4 , then

RM = RA + AM , substitute values

7x + 2 = 3x + 4 + 3x + 4 = 6x + 8 ( subtract 6x from both sides )

x + 2 = 8 ( subtract 2 from both sides )

x = 6

Thus

AM = 3x + 4 = 3(6) + 4 = 18 + 4 = 22

Answer: B: 85 °

Ans:- [tex]\red{\bold{\boxed{156 \degree}}}[/tex]

Answer:

156°

Step-by-step explanation:

The sum of the interior angles of a regular polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 15, thus

sum = 180° × 13 = 2340°

Divide the sum by the number of sides for each interior angle, that is

interior angle = 2340° ÷ 15 = 156°

Answer:

Look below.

Step-by-step explanation:

As 3/2 is the multiplicative inverse (reciprocal) of 2/3, multiply 3/2 to both sides.

6 = 2/3p                            Write the original equation.

6 · 3/2 = 2/3 · 3/2 · p       Multiply the reciprocal of 2/3 (3/2) to both sides.

18/2 = p                            Simplify.

p = 9                                 Simplify.

Answer:

I think it's 4x +8 =100

Step-by-step explanation:

x in this equation is the number of cookies baked last week.

Answer: (7, 9)

Step-by-step explanation: To solve this system, I would use addition.

To solve a system of equations by addition,

we need one of our variables to cancel out.

Notice that we have a 4x in our first equation.

If we had a -4x in our second equation, the x's would cancel.

To create a -4x in the second equation,

we must multiply the entire equation by -4.

So we have (-4)(x + 6y) = (61)(-4).

Rewriting this equation, we have -4x - 24y = -244.

Now let's rewrite both equations.

Now when we add the equations together, the x's cancel.

So we're left with -29y = -261.

Now divide both sides by -29 and we have y = 9.

To find x, we plug a y back in for x in either equation.

So let's go with our second equation, x + 6y = 61.

Plugging a 9 in for y, we have x + 6(9) = 61 or x + 54 = 61.

Subtracting 54 from both sides, we have x = 7.

So x = 7 and y = 9 which we can write as the ordered pair (7, 9).
