Farrah is painting vases to sell in a local craft show. She paints 8 vases in 2 hours. Which is a reasonable estimate of the amount of time it will take her to paint 50 vases?

Answers

Answer 1
The answer is 12 !!!
Answer 2
The Answer is 12.5 hours or 750 mins. H stands for hours and V stands for vases. you are given that 2h = 8v. 1H = 4v; Then 30 mins = 2v; Finally 15 mins= 1v. keep dividing the time until you are left with 1 vase. So then Once you  find the time per vase you Multiply by 50. which is 750 mins and if you're want it in hours divide by 60.

One package of fruit drink contains 6 drinks. Which of the following list the ordered pairs (packages, number of drinks) for 1, 2, 3, and 4 packages of fruit drinks?

Answers

I think this is 

(1,6), (2,12), (3,18), (4,24)

1 package has 6 drinks so that = (1,6)

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%.

-2/3y - 3/4=5 I am very confused

Answers

-2/3y - 3/4 = 5

Add 3/4 to both sides.

-2/3y = 5 + 3/4

Simplify.

-2/3y = 5 3/4

Multiply both sides by -3/2.

-3/2 × -2/3y = 5 3/4 × -3/2

Simplify.

y = 23/4 × -3/2

Simplify.

y = -69/8 AND y = -8 5/9

Is the value of the 1 in 1,440,000 10 times as great as the value of the 4 in the hundred thousands place?

Answers

If you multiply 400,000 by 10 you get 4,000,000. This means that, yes, the value of the 1 is 10 times the 4 in the hundred thousands place. 
Hope I helped :)
Final answer:

The value of the 1 in the number 1,440,000, which is in the million's place, is 2.5 times greater than the value of the 4 which is in the hundred thousand's place.

Explanation:

The value of the 1 in the number 1,440,000 is in the millions place, thus it represents 1,000,000. The 4 on the other hand, is in the hundred thousands place, and thus represents 400,000. The value of the 1 is therefore not just ten times the value of the 4, but in fact, it is 2.5 times greater.

Here is the process: value of 1 = 1,000,000, value of 4 = 400,000, so 1,000,000 / 400,000 = 2.5. Therefore, the value of 1 is 2.5 times the value of 4.

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
