Independent variable: hours (t)

dependent variable:  distance (h)

The independent variable is t (hours) and the dependent variable is d (distance). The total distance (d) will depend on the number of hours (t). As the hours increase, the distance will increase. The distance depends on the amount of time traveling.

ANSWER: t (hours) is the independent variable and d (distance) is the dependent variable

Hope this helps! :)

A bag contains yellow marbles and blue marbles, 73 in total. The number of yellow marbles is 7 more than 5 times the number of b
Roman55 [17]

Answer:

number of yellow marbles=62.

Step-by-step explanation:

It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.

Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.

Now, Total number of marbles= number of yellow marbles+number of blue marbles.

⇒73=x+5x+7

⇒73-7=6x

⇒66=6x

⇒x=11

Therefore, numberof blue marbles=x=11 and

number of yellow marbles=5x+7=5(11)+7=55+7=62.

The Prize Pretzel Company most popular pretzel sells for $4.80 per bag. The table below shows the cost of these pretzels in vari
Over [174]

Answer:

The price of pretzels in 1975 = $1.80

Step-by-step explanation:

To answer this question we are assuming the steady rate means linear.Let x be the year and y be the price.

We need to find the slope

m = (y2-y1)/(x2-x1)

  = (4.80-4.05)/(2015-2005)

  =.75/10

 = .075

The slope is .075

We can use the point slope form of the equation  

y-y1 = m(x-x1)

y-4.80 = .075(x-2015)

Distribute

y - 4.80 = .075x -151.125

Add 4.80 to each side

y - 4.80+4.80 = .075x -151.125+4.80

y =  .075 x - 146.325

We want to find out how much pretzels were in 1975.  Put in x=1975

y = .075(1975) -146.325

y = 148.125-146.325

y=1.80

D-1/2=5/12 what is d??
EleoNora [17]

Answer:

d = \frac{11}{12}

Step-by-step explanation:

1) To solve for d, isolate it in the equation. So, to get rid of the -\frac{1}{2} with the d, add \frac{1}{2} to both sides.

d-\frac{1}{2}  = \frac{5}{12} \\d - \frac{1}{2} +\frac{1}{2} = \frac{5}{12} + \frac{6}{12} \\d = \frac{11}{12}

Thus, d = \frac{11}{12}.
