Mary is making some shirts for her school's drama department. The fabric store has 3 1/6 yards of the fabric she wants in stock. But this quantity of fabric can make only 1 1/3 shirts. What length of fabric does Mary need to buy if she wants to sew 2 shirts?

Answers

Answer 1

Answer: The answer is 4 3/4 yards of the fabric.

This can be calculated using the proportion.
If the 3 1/6 yards of the fabric is enough for 1 1/3 shirts, how many yards are necessary of 2 shirts:
$3 (1)/(6) yards :1 (1)/(3)shirts =xyards:2shirts$

Let's express 3 1/6 as 19/6:
$3 (1)/(6) =3+ (1)/(6) = 3* (6)/(6)+ (1)/(6) = (18)/(6) + (1)/(6) = (18+1)/(6) = (19)/(6)$

Similarly, 1 1/3 = 4/3:
$1 (1)/(3) =1+ (1)/(3) = 1* (3)/(3)+ (1)/(3) = (3)/(3) + (1)/(3) = (3+1)/(3) = (4)/(3)<span>$

Now, let's use this in the proportion:
$3 (1)/(6) yards :1 (1)/(3)shirts =xyards:2shirts$
$(19)/(6) : (4)/(3) = x:2$

Crossing the products:
$x* (4)/(3) =2* (19)/(6)$
⇒ $x* (4)/(3) = (19)/(3)$
⇒ $x = (19)/(3) : (4)/(3)$
$x= (19)/(3) * (3)/(4)$
⇒ $x = (19)/(4) = (16+3)/(4) = (16)/(4) + (3)/(4) =4+ (3)/(4) =4 (3)/(4)$

Therefore, Mary needs in total 4 3/4 yards of the fabric.

Answer 2

Answer:

Answer:

The answer is 4 3/4 yards of the fabric.

What is 340 pages; 20 percent decrease

Answers

The required, 20 percentdecrease from 340 pages is 272 pages.

To calculate a 20 percent decrease from 340 pages, we need to find 20 percent of 340 and subtract it from the original value.

Step 1: Calculate 20 percent of 340:

20% of 340 = (20/100) * 340
= 0.2 * 340
= 68

Step 2: Subtract the result from the originalvalue:

340 - 68 = 272

Therefore, a 20 percentdecrease from 340 pages is 272 pages.

A farmer applied different types of fertilizer to two different sections of his watermelon field. At the end of the growing season, the farmer randomly weighed 20 watermelons from each section. The table shows the mean and the mean absolute deviation (MAD) of the weights for each fertilizer.Fertilizer Mean (lb) MAD
1 24 3
2 22 2
Calculate the means-to-MAD ratio. Can the farmer conclude that Fertilizer 1 generally produces heavier watermelons?

Select from the drop-down menus to correctly answer the question.

The farmer (can, cannot) conclude that Fertilizer 1 generally produces heavier watermelons because the distributions of weights for the two fertilizers are (identical, somewhat similar, similar, different).

Answers

the mean is the average weight.
the MAD is how spread out the weights are from the mean, the higher the number the more spread out, which means you could have more lower weights than higher weights, of more heavy than light

so fertilizer 1 had a higher average weight ( 24 is greater than 22)
and the difference in MAD is only 1 ( 3-2)

so the farmer CAN conclude , because the distribution is SOMEWHAT SIMILAR

Answer:

cannot and similar

at Alan's sports shop, GO FAST trainers cost £40.95 originally and there is a third off in the sale. At Irene's sport shop, GO FAST trainers cost £40.00 originally and there is a discount of 30% in the sale. Which trainers cost less in the sales?

Answers

the trainers will be cheaper at Alan's sport shop.

prices ->
Alan's: 27.30
Irene's: 28.00

$(1)/(3)$ of 40.95 can be calculated as follows ->

$(1)/(3)$ = $(x)/(40.95)$
simplify to get that x = 27.30

30% of 40.00 can be calculated as follows ->

$(30)/(100)$ = $(x)/(40.00)$
simplify to get that x = 28

$at\ Alan's\ sports\ shop:\n\£40.95- (1)/(3) \cdot\£40.95= (2)/(3) \cdot\£40.95=\£27.30\n \nAt\ Irene's\ sport\ shop:\n\£40.00-30\%\cdot \£40.00=70\%\cdot \£40.00=0.70\cdot \£40.00=\£28.00\n \nAns.\ Less\ cost\ is\ at\ Alan's\ sports\ shop.$

3 times the square root of 28??
3√28

Answers

First of all, the square root of 28 is 5.3. That is because 5.3*5.3=28.09 but mainly just 28. So now that we know what the square root of 28 is now we can multiply it by 3.

5.3*3= 15.9

Your final answer is 15.9
