Harry, hannah and howard are all going by train to london to watch the olympics. hannah departs on the 2:15 pm train. harry's tr

ddd [48]

Hanna train departs at 2:15 pm , while harry departs at 3.00 pm and Howard departs at 2:35 pm (20 minutes after Hannah). Howard arrives at 3.25 pm which means he takes 50 minutes. Harry trains takes 50% longer than Howard which is 1.5 × 50 = 75 minutes( 1 hr 15 minutes . Therefore harry arrives at 4.15 pm ( 3.00 + 1 hr 15 minutes).
hence, the answer is 4.15 pm

If you factor the expression, your answer would look like this:
x + x^2 + 4
If you simplify the expression, your answer would look like this:
x^2 + x + 4

Evaluate the line integral, where c is the given curve. (x + 9y) dx + x2 dy, c c consists of line segments from (0, 0) to (9, 1)

viktelen [127]

$\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=\int_C\langle x+9y,x^2\rangle\cdot\underbrace{\langle\mathrm dx,\mathrm dy\rangle}_{\mathrm d\mathbf r}$

The first line segment can be parameterized by $\mathbf r_1(t)=\langle0,0\rangle(1-t)+\langle9,1\rangle t=\langle9t,t\rangle$ with $0\le t\le1$ . Denote this first segment by $C_1$ . Then

$\displaystyle\int_{C_1}\langle x+9y,x^2\rangle\cdot\mathbf dr_1=\int_{t=0}^{t=1}\langle9t+9t,81t^2\rangle\cdot\langle9,1\rangle\,\mathrm dt$
$=\displaystyle\int_0^1(162t+81t^2)\,\mathrm dt$
$=108$

The second line segment ( $C_2$ ) can be described by $\mathbf r_2(t)=\langle9,1\rangle(1-t)+\langle10,0\rangle t=\langle9+t,1-t\rangle$ , again with $0\le t\le1$ . Then

$\displaystyle\int_{C_2}\langle x+9y,x^2\rangle\cdot\mathrm d\mathbf r_2=\int_{t=0}^{t=1}\langle9+t+9-9t,(9+t)^2\rangle\cdot\langle1,-1\rangle\,\mathrm dt$
$=\displaystyle\int_0^1(18-8t-(9+t)^2)\,\mathrm dt$
$=-\dfrac{229}3$

Finally,

$\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=108-\dfrac{229}3=\dfrac{95}3$

Original shirt cost: $55. Current shirt cost $40 find the percent decrease round to the nearest whole percent

ioda

Answer:

Step-by-step explanation:

Original cost = $55

Current price = $40

Decrease in price = 40-55 = -$15

Percentage decrease = [(New price - old price)/ old price] *100

Percentage decrease = (40-55)/55] *100

= -0.272727 *100

= -27.27%

To a whole percentage = 27%

Therefore, the cost of the t-shirt decreased by 27%
