A construction company needs to remove 3 1/6 tons of dirt from a construction site. They can remove 5/8 tons of dirt each hour. What is the total number of hours it will take to remove the dirt?

Answers

Answer 1

This would be 3 1/6 divided by 5/8

3 1/6 = 19/6 so we have

19/6 / 5/8

= 19/6 * 8/5 = 19/3 * 4/5 = 76/15 = 5 1/15 hours answer

Answer 2

The total number of hours it will take to remove the dirt will be 5 ¹/₁₅ hours.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

A construction company needs to remove 3 ¹/₆ tons of dirt from a construction site. They can remove 5/8 tons of dirt each hour.

Convert the mixed fraction number into a fraction number. Then we have

3 ¹/₆ = 19 / 6

The total number of hours it will take to remove the dirt will be given as,

5/8 = (19/6) / Time

Time = (19/6) / (5/8)

Time = (19 x 8) / (5 x 6)

Time = 76 / 15

Time = 5 ¹/₁₅ hours

The total number of hours it will take to remove the dirt will be 5 ¹/₁₅ hours.

Suppose a line has slope - 2/3 and passes through the point (1, 8). Which other point must also be on the graph?

Answers

Final answer:

Another point on the line with a slope of -2/3 passing through (1, 8) is (4, 6). This point is found by moving 3 units right and 2 units down from the initial point.

Explanation:

To find another point on the graph of a line with a given slope and passing through a given point, use the point-slope form of a linear equation.

If a line has a slope of -2/3 and passes through the point (1, 8), we can find another point on the line by moving according to the slope. The slope tells us that for every 3 units we move horizontally (in the x-direction), we move 2 units vertically (in the y-direction), and since the slope is negative, we move in the opposite direction of the increase in x. Hence, starting from (1, 8), if we move 3 units to the right (increase in x), we must move 2 units down (decrease in y).

So to find a new point, we do the following:

Start at the point (1, 8).Move 3 units to the right, which takes us to x = 1 + 3 = 4.Move 2 units down, which takes us to y = 8 - 2 = 6.

Therefore, the point (4, 6) must also lie on the graph of the line.

Which is the better buy 3 pounds for 8.31 or 5 pounds for 12.95

Answers

answer:

5 pounds for 12.95

explanation:

to solve, find the unit rate. the cheaper unit rate is the best and cheapest choice.

8.31/3 = 2.77
12.95/5 = 2.59

5 pounds for 12.95 is the cheaper choice because it has a smaller unit rate.

Hope this helps! :D

It'd be better to buy the 5 pounds for 12.95.

If you divide the price by the amount, it results as 2.59 as opposed to 3 pounds for 8.31 which is 2.77 per pound, making it clear now that the 5 lb for 12.95 is the better deal

The radius of the base of a cylinder is 28 cm and its height is 48 cm. Find the surface area of the cylinder in terms of π.

Answers

Answer: The required surface area of the given cylinder is 4256π cm².

Step-by-step explanation: Given that the radius of the base of a cylinder is 28 cm and its height is 48 cm.

We are to find the surface area of the cylinder in terms of π.

We know that

the SURFACE AREA of a cylinder with base radius r units and height h units is given by

[tex]S.A.=2\pi r(r+h).[/tex]

For the given cylinder, we have

r = 28 cm and h = 48 cm.

Therefore, the surface area of the cylinder will be

[tex]S.A.\\\\=2\pi r(r+h)\\\\=2\pi \times28(28+48)\\\\=56\pi\times 76\\\\=4256\pi~\textup{cm}^2.[/tex]

Thus, the required surface area of the given cylinder is 4256π cm².

there are 36 roses and 27 carnations. anna is making flower arrangements using both flowers, if she made the maximum number of arrangements, how many carnations would be in each?

Answers

Anna can make 9 arrangements. Each has 3 carnations (27 ÷ 9 = 3).

To determine how many carnations would be in each arrangement if Anna made the maximum number of arrangements, we need to find the greatest common divisor (GCD) of 36 and 27.

The GCD of 36 and 27 is 9.

So, Anna can make a maximum of 9 flower arrangements using both roses and carnations.

To find out how many carnations would be in each arrangement, we divide the total number of carnations (27) by the number of arrangements (9):

27 carnations ÷ 9 arrangements = 3 carnations in each arrangement.

Therefore, if Anna made the maximum number of arrangements, there would be 3 carnations in each arrangement.

9 more than than the quotient of -36 an-4

Answers

" the quotient " means divide

9 more then the quotient of -36 and -4...

(-36/-4) + 9 =
9 + 9 =
18

It would be -36 / -4 + 9, or 18.

So here, the first statement is 9 more, so you could change that to +9.

The next statement is the quotient of -36 and -4, which would just be -36 / -4.

So just add the two together to get -36 / -4 + 9.

To find the solution of this, use PEMDAS, or the order of operations.

So do -36 / -4 first, which would result in 9 because that's how many negative fours there are in -36, resulting in 9 + 9.

9 + 9 is 18.

Find the percent error of the measurement 7 cm.

Answers

The answer is 7.14 :)

Answer:

The percent error of the measurement 7 cm is 7.14%.

Step-by-step explanation:

Given : Measurement 7 cm

To find : The percentage error of the given measurement.

Solution :

First we find the error in the measurement.

Measuring to the nearest centimeter means the true value could be up to half a meter smaller or larger.

i.e It is upto 0.5 (between 6.5 and 7.5)

Measurement - 7 ±0.5 cm

Absolute Error = 0.5 cm

Relative Error = [tex]\frac{0.5}{7}=0.0714[/tex]

Percentage Error = [tex]0.0714\times 100=7.14\%[/tex]

Therefore, The percent error of the measurement 7 cm is 7.14%.
