Gail bought 1180 buttons to put on the shirts she she makes. She uses 6 buttons for each shirt. How shirts can Gail make with th

stepladder [879]

To answer this question, we need o divide.

Since she has 1180 buttons, we can divide that number by the amount of buttons it takes to make a shirt, 6.

1180/6=196

Hope this helps!

troy is going to spain and needs to convert his dollars to euros. He knows that when he goes, $5.00 is equivalent to about 3.45

astraxan [27]

Answer:

Step-by-step explanation:

3.45/5=0.69

0.69x$125=86.25

0.75x$125=93.75

93.75-86.25=$7.5

Troy would get $7.50 more than he would have if the exchange rate had stayed at .69

Find the value of x. Round to the nearest tenth PLEASE HELP

ololo11 [35]

Answer:

x = 38.2°

Step-by-step explanation:

sin 27° = x°

11 15

15 · (sin 27°) = 11 · x°

cross-multiply:

6.81 = 11x

6.81 / 11 = x

x = 0.619

sin^-1 (0.619) = 38.2°

9,13,43,55 what is the mean absolute deviate (MAD) of their ages

lisov135 [29]

Answer:

The mean absolute deviation of this data $\{9,13,43,55\}$ is $MAD =19$ .

Step-by-step explanation:

The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

The steps to find the MAD include:

find the mean (average)
find the difference between each data value and the mean
take the absolute value of each difference
find the mean (average) of these differences

To find the mean absolute deviation of this data $\{9,13,43,55\}$ you must

Step 1: Calculate the mean.

$\:mean=\bar{x}= \frac{9+13+43+55}{4} =\frac{120}{4}=30$

Step 2: Calculate the distance between each data point and the mean and take the absolute value of each difference .

$|9-30|=21\\|13-30|=17\\|43-30|=13\\|55-30|=25$

Step 3: Add the distances together.

$21+17+13+25=76$

Step 4: Divide the sum by the number of data points.

$MAD = \frac{76}{4} =19$

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the curves about the given

Fed [463]

See attachment for one such shell. The volume is given by the sum of infinitely many thin shells like this, each with radius $x$ and height determined by the vertical distance between the upper blue curve and the lower orange curve for any given $x$ , i.e. $8e^x-8e^{-x}$ .

The volume is then

$2\pi\displaystyle\int_0^1x\left(8e^x-8e^{-x}\right)\,\mathrm dx=16\pi\int xe^x(e^{2x}-1)\,\mathrm dx=\dfrac{32\pi}9(e^3-4)\approx179.677$
