i need to fill in the blank

Answers

Answer 1
The answer is:  " 2 " .
__________________________________________________
Note:  Given:  6:1::12:x ;  Solve for "x" ;

Rewrite as:

6/1 = 12/x ;

6x = (12)*(1) ;

6x = 12 ;

Divide EACH SIDE of the equation by "6" ; to solve for "x" ;

6x / 6 = 12 / 6 ; 

 x = 2 .
_______________________
Answer 2

Answer:

6:1 = 12:2

Step-by-step explanation:

In the second statement, we see that 12 is double the amount of the original, meaning it had been multiplied by 2.  

Apply the same rule to the second part of the ratio.

Equation: 1 x 2 = 2

Conclusion: 6:1 = 12:2

1. Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. Happy Hounds charges a flat fee of $21 plus $1 per hour. For how many hours is the total fee charged by the companies the same?

Answers

x represents the amount of hours
peppy pets 15 + 3x
happy hounds 21 + x

15 + 3x = 21 + x
subtract x from both sides

15 + 2x = 21
subtract 15 from both sides

2x = 6
divide each side by 2

x = 3 hours


Algebraic equations are equations that consist of unknown variables. These variables can be represented using the letters of the alphabet.

The total fee charged by the companies will be the same in 3 hours.

Let's represent the number of hours as :h

Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. The algebraic equation to represent this statement is given as:

$15 + $3 x h

15 + 3h ..........Equation 1

Happy Hounds charges a flat fee of $21 plus $1 per hour. The algebraic equation to represent this statement is given as:

$21 + $1 x h

21 + h ..........Equation 1

We equate both equations to each other

Equation 1  = Equation 2

15 + 3h  = 21 + h

Collect like terms

3h - h = 21 - 15

2h = 6

Divide both sides by 2

2h/2 = 6/2

h = 3

Therefore, the total fee charged by the companies will be the same in 3 hours.

How many solutions does this equation have 3(x+11) = 6(x+ 33)

Answers

divide both sides by 3

expand

subtract x from both sides

simplify 2x + 66 - x to x + 66

subtract 66 from both sides

simplify 11 - 66 to -55

switch sides

x = -55

Answer: this equation 3(x + 11) = 6(x + 33) has only ONE solution and that would be x = -55.

What is 0.21212121.... as a fraction

Answers

if numbers repeat, it's problby divided by 9 or some multipule of 9

if 2 numbers repeat, it's probbalby divided by 99


like 0.abababababab=ab/99


so
0.21212121
21 repeats
so it is 21/99 or 7/33
If we make the number equal to x...
0.21212121.... = x 
multiply each side by 100
21.212121.... = 100x 
remember that x is 0.21212121? we can subtract that now from 21.21212121, as well as x from 100.
21.212121... - 0.212121... = 100x - x 
we are left with 21 = 99x
21 = 99x 
simplify....
7 = 33x 
and divide!
7/33 = x


Your answer is: 0.2121212121.... = 7/33

Ashely walks 2 1/2 miles around a lake around three times a week. If Ashley walks around the lake in 3/4 hour,what is her rate of speed? (Hint: Use the formula r= d/t, where the r is rate, d is distance, and t is time.

Answers

To find Ashley's rate of speed in miles per hour, you will use the formula

Rate = Distance/Time.

First, you should fill in what you know. In this case, you know the distance is 2.5 miles, and the time is 0.75 hours. Now, you simply plug in the known variables to the formula to get Rate = 2.5 miles / 0.75 hours. After dividing, you reach the answer Rate = 3.333333 (or 3 and 1/3) miles/hour.

A scuba diver starts at 85.6 meters below the surface and descends until he reaches 103.2 meters below sea level. How many meters did he descend ?

Answers

188.8 meters because you have to add 103.2+85.6 = 188.8 meters
Final answer:

The scuba diver descended 17.6 meters.

Explanation:

To find the distance the scuba diver descended, subtract the starting depth from the ending depth. In this case, the starting depth is 85.6 meters below the surface and the ending depth is 103.2 meters below sea level. So, the distance the scuba diver descended is 103.2 - 85.6 = 17.6 meters.

Hollis and Charmaine are curious about which mode of transportation gets them from their apartment to the mall faster. Hollis takes public transportation and gets to the mall in 18.5 minutes. Charmaine rides her bike and gets to the mall in 0.5 hours. The mall is 2.4 miles away from their apartment. Use the formula for distance traveled, distance=rate⋅time, to find each rate of travel in miles per minute. What is the difference between Hollis' rate of travel on the bus and Charmaine's rate of travel on the bike? In other words, how much faster is it to take the bus in miles per minute? Enter your answer as a decimal, rounded to the nearest hundredth, if necessary, like this: 42.53 50 pts

Answers

Hollis travels 0.05 miles per minute faster than Charmaine. First, convert to the same units for both Hollis and Charmaine. So Hollis takes 18.5 minutes and Charmaine takes 0.5*60 = 30 minutes. Both girls travel 2.4 miles, so calculate how many miles per minute each takes Hollis = 2.4 / 18.5 = 0.13 miles per minute. Charmaine = 2.4 / 30 = 0.08 miles per minute. Finally determine the difference in speed between the two girls. 0.13 - 0.08 = 0.05 miles per minute.

What is the y-intercept of the equation of the line that is perpendicular to the line y = x + 10 and passes through the point (15, –5)?

The equation of the line in slope-intercept form is y = x +

Answers

y = x + 10 has slope = 1
perpendicular lines, slope is opposite and reciprocal
so perpendicular line slope = -1
passes through the point (15, –5)
y = mx + b 
-5 = -1(15) + b
b = -5 + 15
b = 10 
y -intercept : 10

The equation of the line in slope-intercept form is y = -x + 10

3. The equation below represents how many hours, x, it will take to travel 210 miles at an average speed of 60 miles per hour.
How long will it take? 60x210

Answers

1.    4x=$36.00  x = 9 cupcakes                                                                            2.    15-3=x   x = 12 years old                                                                                3.     210/60 = x   x = 3.5 hours 




Final answer:

To solve the given problems, use linear equations: for cupcakes, 4x = 36; for Sam's age, x = 15 - 3; and for travel time, 210 = 60x.

Explanation:

1. To find how many cupcakes, x, can be purchased for $36.00 when each cupcake costs $4.00, we use the equation 4x = 36. This equation represents the cost of cupcakes multiplied by the number of cupcakes equals the total cost.

2. For determining Sam's age, given that Sam is 3 years younger than Marco, who is 15 years old, we represent Sam's age with x. The equation to calculate Sam's age would be x = 15 - 3.

3. The equation presented as 60x210 seems to be a mistake. To find out how many hours, x, it will take to travel 210 miles at an average speed of 60 miles per hour, the correct equation is 210 = 60x.

Number 3 and how you got the answer

You have the correct steps and final answer. The area of the room is 196 square feet, so each side is sqrt(196) = 14. The perimeter is 14*4 = 56 feet. You'll need 6 boards (each 10 ft long) to get 60 ft total. You'll have 60-56 = 4 ft of board left over. This is assuming that there isn't any other type of waste or mistakes made in cutting.

Jesse and three friends buy snacks for a hike. They buy trail mix for $5.42, apples for $2.55, and granola bars for $3.99. If the four friends split up the cost of the snacks equally, how much should each friend pay?

Answers

2.99 because you add the total cost up, which would be 11.96. So then you would divide 11.96 by 2.99 which gives you 2.99


Add all the numbers up which equals up to 11.96. Then divide 11.96 into 4. it equals 2.99 so each friend is gonna pay 2.99
