Jenna works in an ice cream shop. When she starts her shift the tub of chocolate ice cream is 2/3 full. When she finishes her shift 6 1/2 h later, there is only 1/6 of the tub left. What was the average hourly change in tub fullness?

IMMEDIATE PLEASE.

Answers

Answer 1

Answer:

[tex]-1/13\text{ tub per hour}[/tex]

Step-by-step explanation:

First, let's find how much of the tub was used within the time.

We know that the tub was 2/3 full was Jenna started.

And it was only 1/6 full when Jenna ended.

Therefore, to find the amount used, we can subtract 1/6 from 2/3. So:

[tex]u=\frac{2}{3}-\frac{1}{6}[/tex]

Make a common denominator. Change 2/3 to 4/6 by multiplying both layers by 2. So:

[tex]u=\frac{4}{6}-\frac{1}{6}[/tex]

Subtract and reduce:

[tex]u=\frac{3}{6}=\frac{1}{2}[/tex]

Therefore, 1/2 of the tub was used after 6 1/2 hours.

To find the average hourly change, we will put the amount used over the amount of hours. 6 and 1/2 hours is the same as 13/2 hours. Therefore, the hourly change will be:

[tex]c=\frac{\frac{1}{2}}{\frac{13}{2}}[/tex]

Remember when dividing fractions, we:

1) Flip the divisor (the second number).

2) Change the division sign to a multiplication sign.

3) Multiply.

So:

[tex]c=\frac{1}{2}\div\frac{13}{2}\\\Rightarrow c=\frac{1}{2}\times \frac{2}{13}[/tex]

Multiply straight across and reduce:

[tex]c=\frac{2}{26}=\frac{1}{13}[/tex]

However, since we are using up the tub, our rate will be negative. Therefore:

[tex]c=-\frac{1}{13}[/tex]

Therefore, the average hourly rate was -1/13 tub per hour.

This means that after each hour, 1/13 of the tub will be used up.

Edit: Corrected Wrong Answer

Answer 2

Answer: -1/13 of a tub per hour

Step 1: Subtract.

2/3 - 1/6 = ?

Step 2: Find the common denominator.

4/6 - 1/6 = 3/6.

Step 3: Simplify the fraction.

3/6 = 1/2

Step 4: Put 1/2 over 13/2.

1/2 over 13/2

Step 5: Flip divisor around. Then divide.

1/2 ÷ 13/2

Step 6: Multiply.

1/2 × 2/13 = 2/26.

2/26 reduced = 1/13.

Since it was used, now it is -1/13

Answer = -1/13 of a tub per hour

Write the equation of the line that is perpendicular to the line y=(-1/5)x+9 and passes through the point (-2,-2)

Answers

Answer:

y = 5x + 8

Step-by-step explanation:

Recall that if two lines are perpendicular, their slopes are negative reciprocals of one another.  Thus, given y = (-1/5)x + 9, the slope of any perpendicular is

           -1

m = --------- = 5

        (-1/5)

Starting out with the slope-intercept equation y = mx + b, we get:

-2 = 5(-2) + C, or C = 8

Thus, the desired equation is

y = 5x + 8

The equation of the line that is perpendicular to the given line is y=5x+8.

Given that, the equation of line y=(-1/5)x+9 and passes through the point (-2,-2).

What is slope of an equation?

The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis.

If m is the slope of a line, then the slope of a line perpendicular to it is -1/m.

Now, slope =-1/5

-1/m = 5

Put m=5 and the point (-2, -2) in y=mx+c and simplify

That is, -2=5(-2)+c

⇒c=8

Substitute m=5 and c=8 in y=mx+c, we get y=5x+8

Therefore, the equation of the line that is perpendicular to the given line is y=5x+8.

Which equation represents a line which is parallel to the line 7x-5y=-30?

Answers

Answer:

Y=7/5x+8

Is the answer to question don't ask me how I know I cheated

The equation y = 7x/5 + b represents a line which is parallel to the line 7x-5y=-30.

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

We have an equation,

7x-5y=-30

Simplifying,

y = 7x/5 + 30/5

y = 7x/5 + 6.

The general formula of line parallel to a given line is,

y = 7x/5 + b, where b is the y-intercept of the line.

Therefore, y = 7x/5 + b is the required line.

Ingrid's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot. If Ingrid's curtain company wants to make 64 curtains, how many feet of fabric will she need? 1 inch = 1 12 foot I just don't get it

Answers

Answer:

192 ft

Step-by-step explanation:

Number of curtains = 64

Length of each curtains = 36 inches

Total length of curtains = Number of curtains × Length of each curtains

= 64 × 36 inches

= 2,304 inches

1 inch = 1/12 foot

2,304 inches = 2,304 / 12 ft

2,304 inches = 192 ft

She will need 192 ft of the fabric to make 64 curtains each of length 36 inches
