Well I can see where you have the issue. This is actually a simple fraction problem. Let's begin.

Step 1: Determine the prices of the fabric, per every 10th of a meter.
Since we know that 10/10 of a meter=1 meter, divide 3.30 by 10 to get the price per 10th of a meter which is .33.

Step 2: Determine the price of the blue fabric.
Since the blue fabric requires 2.3 meters (or 23/10) we can multiply .33 by 23 and have the pricing for the blue fabric, which is 7.59.

Step 3: Determine the price of the white fabric.
Since we know that there is 3.5 meters of white fabric (or 35/10) we can multiply .33 by 35 and again have the pricing, which is 11.55.

Step 4: Determine the price of the red fabric.
Since we know that the costume requires 0.6 meters of red fabric (or 6/10) we multiply .33 by 6 and get the pricing for red, which is 1.98.

Step 5: Add these three numbers up to get the total price of the costume.
7.59+11.55+1.98=21.12

Step 6: Subtract the cost of the fabric from the total budget to see how much money Kelly has left.
40.00-21.12=18.88

Since the problem does not specify any other costs other than the fabric and accessories, the assumed amount left for accessories is C: $18.88

A balloon is rising vertically at the rate of 12 feet per second; at the same time, it is being blown horizontally by a wind of

Nuetrik [128]

Answer:

Angle is 33.82°

Step-by-step explanation:

It is given that, from the figure below,

Vertical distance = 12 feet

Horizontal distance = 18 feet.

Using the trigonometric rule for the right triangles, we have,

$\tan x=\frac{perpendicular}{base}$

i.e. $\tan x=\frac{12}{18}$

i.e. $\tan x=0.67$

i.e. $x=\arctan 0.67$

i.e. x= 33.82°

Thus, the angle made by the path with the horizontal is 33.82°.

Solve each system using substitution or additions (elimination). -x+2y=-1 5x-10y=6

NNADVOKAT [17]

Answer:

Step-by-step explanation:

L1 -x + 2y = -1

L2 5x - 10y = 6

-x + 2y = - 1 multiply by -1

x - 2y = 1 multiply by 5

5x - 10y = 5 is similar that 5x - 10y = 6

The system has no solution

A recent survey of 128 high school students indicated the following information about release times from school.

Delicious77 [7]

Answer:

A) Interval estimate for those that want to get out earlier = (35%) ± (4%) = (31%, 39%)

Interval estimate for those that want to get out later = (39%) ± (4%) = (35%, 43%)

B) The group that wants to get out of school earlier can win after all the votes are counted if their true population proportion takes on a value that is higher than the closest true population proportion (for the group that wants to get out of school later)

That is, in the (31%, 39%) and (35%, 43%) obtained in (a), a range of (35.1%, 39%) and (35%, 38.9%) show how possible that the group that wants to get out of school earlier can win after all the votes are counted.

Step-by-step explanation:

The Interval estimate for the proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Interval estimate = (Sample proportion) ± (Margin of error)

Margin of Error is the width of the confidence interval about the proportion.

a) Find the interval estimates

i) for those that want to get out earlier and

ii) those that want to get out later.

i) Sample proportion of those that want to get out earlier = 35%

Margin of Error = 4%

Interval estimate for those that want to get out earlier = (35%) ± (4%) = (31%, 39%)

ii) Sample proportion of those that want to get out later = 39%

Margin of Error = 4%

Interval estimate for those that want to get out later = (39%) ± (4%) = (35%, 43%)

b) Explain how it would be possible for the group that wants to get out of school earlier to win after all the votes are counted.

Since the interval estimates represent the range of values that the true population proportion can take on for each group that prefer a particular option, the group that wants to get out of school earlier van have their proportion take on values between 31% and 39%. If their true population takes on a value that is highest (which is very possible from the interval estimate), and the group with the highest proportion in the sample, (the group that wants to get out of school later, whose true population proportion can take between 35% and 43%) has a true population proportion that is less than that of the group that wants to get out of school earlier, then, the group that wants to get out of school earlier can win after all the votes are counted.

Need help asap plz <3✨ PLEASE ANSWER THE QUESTION THX :)

Artemon [7]

Answer:

It equals a negative number because there's a negative and a positive which will result in a negative answer

Step-by-step explanation:

if there's a negative and a positive the result will be negative

if it's two negative result would be positive :

-1 × -1 = +1

-1 × +1 = -1

+1 × +1 = +1

-1 × -1 × -1 = -1

-1 × -1 × +1 = +1
