Answer:

13 hours and 12 minutes 

Step-by-step explanation:

You put 3.25 as a fraction which is 3 1/4. then I took 3 1/4 and misused it by 11 1/2. 23/2 - 13/4 = 8 1/4 then we took the 5/8 and divided it by 33/4 (3 1/4) I got 13 1/5. 13 1/5 is 13 hours and 12 minutes.

Minimum amount of time taken to complete the hole is 13 hours and 12 minutes.

In mathematics, proportion is an equation where two ratios are taken to be equal to each other. Suppose if a:b = c:d, then [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex].

In the question, it is given that, a hole is already dug to a depth of 3.25 feet = 3 [tex]\frac{1}{4}[/tex] feet.

Also, the depth of hole at the end of the day must be atleast 11 [tex]\frac{1}{2}[/tex] feet.

Remaining depth of the hole needed to dug = 11 [tex]\frac{1}{2}[/tex] - 3 [tex]\frac{1}{4}[/tex] = [tex]\frac{23}{2}[/tex] - [tex]\frac{13}{4}[/tex] = [tex]\frac{33}{4}[/tex] feet

Rate of digging is [tex]\frac{5}{8}[/tex] feet per hour.

We have to find how much time will be taken for  [tex]\frac{33}{4}[/tex] feet.

In proportional form, it can be written as  [tex]\frac{5}{8}[/tex] : 1 = [tex]\frac{33}{4}[/tex] : x, where x is the time taken to complete  [tex]\frac{33}{4}[/tex] feet.

⇒  [tex]\frac{5}{8}[/tex] / 1 =  [tex]\frac{33}{4}[/tex] / x

Cross multiplying, we get

 [tex]\frac{5}{8}[/tex] × x = [tex]\frac{33}{4}[/tex] × 1

⇒ x =  [tex]\frac{33}{4}[/tex] × [tex]\frac{8}{5}[/tex] = [tex]\frac{66}{5}[/tex] = 13 [tex]\frac{1}{5}[/tex]

Hence the minimum amount of time the equipment must continue at the present rate to complete the hole on schedule is 13 hours and 12 minutes.

Answer:

To write an inequality, you need to write a number on the number line, and to graph it, you need to write another inequality and figure out what the answer is.

hope this helped.

Answer:

Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :

y = 1.87x + 3.66

predicted amount of tip for 100 customers = $191

The predicted amount of tips received of 100 customers are served :

y = 1.87x + 3.66

x = 100 ; substitute x = 100 into the equation

y = 1.87(100) + 3.66

y = 187 + 3.66

y = 190.66

Hence, about $191 would be received on tips if 100 customers are recorded.

Using a regression calculator to make prediction from a data table :

Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

Answer:

75%

Step-by-step explanation:

We can see that our fraction is 75/100, which means that 36/48 as a percentage is 75%.

Answer:

75%

Step-by-step explanation:

To find the percentage of successes, simply divide the number of successes by the number of tries. Hence 36/48=.75. Then, multiply by 100% to get the percentage value --> .75x100%=75%

you need similar denominators.

13 4/5 x 2 = 13 8/10

13 8/10 + ? = 8 1/10

8 1/10 + 5 7/10 = 13 4/5

Answer: I think that it is 32

Step-by-step explanation: I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

Answer:

-1/2x-2

Step-by-step explanation:

Distribute the negative sign from the right side to make the equation positive

1/4x - 7 + (-1)(3/4x) + (-1)(-5)

(basically multiplying -1 to 3/4x and -5 to eliminate it)

1/4x - 7 + -3/4x+ 5

Make the equation similar

(1/4x + -3/4x) + (-7 + 5)

combine like terms

1/4x + -3/4x = -2/4x --> Simplifies to -1/2x

Do the other integers

-7 + 5 = -2

Put it together

-1/2x-2
