When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88

Natali5045456 [20]

Uh, so, you're median is 81 already.

Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2.

However, if you're trying to add a number in, adding 81 as it is would work as well.

Hope this helps!

Sara makes and sells bracelets. She bought material for $28.50 and used it all to make 15 bracelets. Sara used the equation to d

Norma-Jean [14]

Answer:

Sara should sell each bracelet at $8.50 to make a profit of $99.

Step-by-step explanation:

We are given the following:

Total cost = $28.50

Total bracelets to be made = 15

Total profit to be made = $99

Let $x$ be the price at which Sara sells each bracelet to make a profit of $99.

$\text{Total sales done = Number of bracelets sold }\times \text{ Sales price of each bracelet}\\$

$\Rightarrow 15 \times x ...... (1)$

Also,

$\text{Total sales price = Total Cost}+ \text{Total Profit} \\$

$\Rightarrow \$28.50 + \$99 ....... (2)$

Equating (1) and (2):

$\Rightarrow 28.50 + 99 = 15x\\\Rightarrow x = \dfrac{127.5}{15}\\\Rightarrow x = $8.50$

Sara should sell each bracelet at $8.50 to make a profit of $99.

HELP ME solve for the right triangle

VikaD [51]

Answer:

see explanation

Step-by-step explanation:

Using the cosine and tangent ratios in the right triangle

cos41° = $\frac{adjacent}{hypotenuse}$ = $\frac{VW}{VX}$ = $\frac{7}{VX}$

Multiply both sides by VX

VX × cos41° = 7 ( divide both sides by cos41° )

VX = $\frac{7}{cos41}$ ≈ 9.3

-----------------------------------------------------------------------

tan41° = $\frac{opposite}{adjacent}$ = $\frac{WX}{VW}$ = $\frac{WX}{7}$

Multiply both sides by 7

7 × tan41° = WX, thus

WX ≈ 6.1

-------------------------------------------------------------------------

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for ∠ X

∠ X = 180° - (90 + 41)° = 180° - 131° = 49°

what is the final amount of $3050.00 that is put into a savings account with 8% interest rate for 25 years, if the interest is c

Anna71 [15]

The formula required is:
$A=P(1+\frac{r}{n})^{nt}$
where A is the amount after t years of the principal P invested at an annual interest rate r (expressed as a decimal fraction) compounded n times per year.
Plugging in the given values, we get:
$A=3050(1+\frac{0.08}{4})^{(4\times25)}=22,096.17$
The final amount is $22,096.17
