3 0

Answer:

(5, 2 )

Step-by-step explanation:

5x + 2y = 29 → (1)

x + 4y = 13 → (2)

multiplying (1) by - 2 and adding to (2) will eliminate y

- 10x - 4y = - 58 → (3)

add (2) and (3) term by term to eliminate y

- 9x + 0 = - 45

- 9x = - 45 ( divide both sides by - 9 )

x = 5

substitute x = 5 into either of the 2 equations and solve for y

substituting into (2)

5 + 4y = 13 ( subtract 5 from both sides )

4y = 8 ( divide both sides by 4 )

y = 2

solution is (5, 2 )

X divided by 0.25 = 7 What is x equal to?

Mkey [24]

Answer:

$x = 1.75$

Step-by-step explanation:

Step 1: Make an equation

x divided by 0.25 = 7

$\frac{x}{0.25}=7$

Step 2: Multiply both sides by 0.25

$\frac{x}{0.25} *\frac{0.25}{1} = 7 * 0.25$

$x = 1.75$

Answer: $x = 1.75$

Cassie’s broker charges her a commission of $4.25 for every ten shares of stock bought or sold. cassie buys 92 shares of hyren a

Kisachek [45]

Cassie's total spent is equal to money spent on shares bought and commission charges of broker.

Money spent on shares bought:

92 shares of Hyren Airlines at $13.70 per share = $92*13.7=1260.4$
130 shares of Giaco Household Goods at $3.28 per share = $130*3.28=426.4$
126 shares of Iwad Records at $8.06 per share = $126*8.06=1015.56$

The sum total is $1260.4+426.4+1015.56=2702.36$ dollars

Commission charges of broker:

If broker charges $4.25 every 10 shares, he charges $\frac{4.25}{10}=0.425$ dollars per share.

Total number of shares bought by Cassie is $92+130+126=348$ shares.

Total spent on commissions, thus, is $348*0.425=147.9$ dollars.

Cassie's total money spent is $2702.36+147.9=2850.26$ dollars.

Rounded to nearest dollar, it is $2850.

Find volume of cone z=sqrt(x^2+y^2) that is bounded with z=5 and z=7

Nina [5.8K]

Convert to cylindrical coordinates first, using

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}$

Then the volume is

$\displaystyle\int_{\zeta=5}^{\zeta=7}\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=\zeta}r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta$
$=\displaystyle\pi\int_{\zeta=5}^{\zeta=7}\zeta^2\,\mathrm d\zeta$
$=\dfrac{218\pi}3$
