Answer:

x=113º

Step-by-step explanation:

67 + x is a linear pair

they would be supplementary if they were next to each other

the 67º represents the acute angle directly next to xº

so

x+67= 180º

subtract 67º from both sides

180-67=113

x=113º

both will give you the same amount of money, $100,000, so I would consider the fact that I'd rather only have 200 people give me money then 500. So I would say 200 people giving me $500 would be the best option

Denise has 3 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 8mph and walks back at a speed of 2mph, how long should she plan to spend walking back?

Answers

Answer:

Denise should plan to spend 36 minutes walking back.

Step-by-step explanation:

Let 'x' reflect the amount of time spent running in hours, then 3-x represents the time spent walking in hours.

here , we know,

           [tex]Distance= Speed \times time[/tex]

Given the values ,

[tex]Distance= 8x[/tex]  

[tex]speed=2mph[/tex]

[tex]Time=(3-x)hours[/tex]

Now , putting these values ,

[tex]8x=2(3-x)[/tex]

[tex]8x=6-2x[/tex]

[tex]10x=6[/tex]

[tex]x=\frac{6}{10}[/tex]

[tex]x=\frac{3}{5}[/tex]

[tex]\frac{3}{5} \times 60[/tex] = 36minutes (converting hours into minutes that is 1 hour = 60 minutes )

Hence , the answer is 36 minutes .

As a director of operations for a fast-food company, you oversee two of the company's restaurants. One of the stores reports their revenue for the year as 0.15 of the company's revenue, and the other restaurant reports 21% of the company's revenue. What is the total percentage of the company's revenue that your two stores report? 3.6% 6% 21.15% 22.5% 36%

Answers

Answer:

Total = 36%

Step-by-step explanation:

Given

Company A = 0.15

Company B = 21%

Required

Determine the total revenue

Total is calculated as thus:

Total = Company A + Company B

Total = 0.15 + 21%

Represent 0.15 as %

Total = 0.15*100% + 21%

Total = 15% + 21%

Total = 36%

Answer:

$16

Step-by-step explanation:

20/5 = 4

4 x 4 = 16

Have a good day!

Answer:  Choice A) $16

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

Work Shown:

5 notebooks = 20 dollars

5/5 notebooks = 20/5 dollars ..... divide both sides by 5

1 notebook = 4 dollars ..... unit rate

4*(1 notebook) = 4*(4 dollars) .... multiply both sides by 4

4 notebooks = 16 dollars

---------------

Another approach:

(5 notebooks)/(20 dollars) = (4 notebooks)/(x dollars)

5/20 = 4/x

5*x = 20*4 ... cross multiply

5x = 80

5x/5 = 80/5 .... dividing both sides by 5

x = 16

So 4 notebooks cost $16

f(x)=-3x+12 represents the amount of ounces of juice left in a bottle after you take x gulps. How many gulps did you take if there are 3 ounces left?

Answers

Answer:

3 gulps

Step-by-step explanation:

In this problem, f(x) = 3. Plug this into the equation:

3 = -3x + 12

Solve for x:

3 - 12 = -3x + 12 - 12

-9 = -3x

-9 / -3 = -3x / -3

3 = x

3 gulps

Answer this question showing work. 2b − 7 ≥− 14 + 2b

Answers

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

First you write out your inequality:

[tex]2b-7\geq -14+2b[/tex]

So first we will subtract 2b on both sides:

[tex]-7\geq -14[/tex]

Since they both canceled out each other we are now left with [tex]-7\geq -14[/tex]

So anyways let's add 7 to both sides:

[tex]0\geq -7[/tex]

I know this might be confusing but the answer is all real numbers.

Mark Went to the store and purchase nine pairs of socks and three packages of undershirts for $8.28 each he also purchase a pair of pants for $32 he spent a total of $77.99 how much did he pay for each pair of socks write an equation using the variable S

Answers

Answer:

He paid $2.35 for each pair of socks.

An equation using the variable S is

$77.99 = 9S + (3 × $8.28) + $32

Step-by-step explanation:

Let S be the cost of a pair of socks

From the question, Mark purchase nine pairs of socks, that is, the total cost of the pairs of socks is 9S

He purchase three packages of undershirts for $8.28 each; the total cost of the three packages of shirt will be 3 × $8.28 = $24.84

and he also purchase a pair of pants for $32

Since he spent a total of $77.99, we can write that

$77.99 = 9S + (3 × $8.28) + $32

Now, we can determine S, the cost of a pair of socks

$77.99 = 9S + (3 × $8.28) + $32

$77.99 = 9S + $24.84 + $32

$77.99 = 9S + $56.84

9S = $77.99 - $56.84

9S = $21.15

S = $21.15/9

S = $2.35

Hence, he paid $2.35 for each pair of socks.
