He earns $150 a week so he has to earn $70 from hair products. By dividing $70 by .05, we see that $70 is 5% of $1,400. Jordan must sell $1,400 worth of hair products to earn $250.

A circle with radius of \greenD{6\,\text{cm}}6cmstart color #1fab54, 6, start text, c, m, end text, end color #1fab54 sits insid

Diano4ka-milaya [45]

Answer: $141 cm^{2}$

Step-by-step explanation:

We have two circles:

Cirlce 1, with a radius $r=6 cm$ and area $A_{1}$ :

$A_{1}=\pi r^{2}$

And Cicle 2, with a radius $R=9 cm$ and area $A_{2}$ :

$A_{1}=\pi R^{2}$

Since Circle 1 is inside Circle 2 and assuming the area of the shaded region is the shown in the attached image, its area is:

$A=A_{2}-A_{1}=\pi R^{2}-\pi r^{2}$

$A=\pi (R^{2}- r^{2})$

$A=\pi ((9cm)^{2}- (6cm)^{2})$

Finally:

$A=141.37 cm^{2} \approx 141 cm^{2}$

Your family visited Disney World Orlando, FL. The 823.5 mile trip took 11.5 hours. How fast did your family travel?

9966 [12]

To solve this, use the equation speed = distance / time. S = D/t for short. The equation automatically gives you the distance and time it took, so this is pretty simple.

823.5/11.5 = 71.608695652173913043478260869565 miles per hour.

71.61 mph would probably work though. XD

Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.33 and a standard deviation of 1.5. U

never [62]

"97.5" will be the American women's % having their shoe sizes that are no more than 11.33.

Given values are:

Mean = 8.33
Standard deviation = 1.5

Now,

= $8.33 + 2\times 1.5$

= $11.33$ (2 above Standard deviation)

→ The data values are between 8.33 and 11.33,

= $\frac{95}{2}$

= $47.5$ (%)

→ The data value below 11.33,

= $50$ (%)

hence,

→ The percentage of American women will be:

= $50+47.5$

= $97.5$ (%)

Thus the above answer is appropriate.
