C.) 27 and a half. 12 minutes times 5 equals an hour so 5 and a half pages times 5 equals 27 and a half pages per hour.

Two sides of a triangle are equal in length and double the length of the shortest side. The perimeter of the triangle is 36 inch

chubhunter [2.5K]

Answer:

Two equal sides = 14.4 inches each

Shortest side = 7.2 inches

Step-by-step explanation:

a + b + c = 36

a = b

a = 2c

then:

c = a/2

a + a + a/2 = 36

2a + a/2 = 36

4a/2 + a/2 = 36

5a/2 = 36

a = 2*36/5

a = 72/5

a = 14.4

a = 2c

14.4 = 2*c

c = 14.4/2

c = 7.2

a = b

b = 14.4

Check:

14.4 + 14.4 + 7.2 = 36

A paper company needs to ship paper to a large printing business. The paper will be

Kryger [21]

Answer:

x = 8

y = 11

Step-by-step explanation:

Total small box weight = 50x [x being the number of small boxes]

Total large box weight = 80y [y being the number of large boxes]

Total boxes = x+y = 19

Total weight = 1280

Determine x and y.

You know 2 equations. One for weight and another for number of boxes each.

1280 = 50x +80y
x+y = 19

Rewrite second equation:

x+y=19

y=19-x

You have to plug in one into another.

1280 = 50x + 80(19-x)

Solve for x

1280 = 50x + 1520 - 80x

-240 = -30x

x = 8

Solve for y by plugging in x into one of the equations:

8+y = 19

y = 11

Find the length of the curve y = integral from 1 to x of sqrt(t^3-1)

Arlecino [84]

$y=\displaystyle\int_1^x\sqrt{t^3-1}\,\mathrm dt$

By the fundamental theorem of calculus,

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm d}{\mathrm dx}\displaystyle\int_1^x\sqrt{t^3-1}\,\mathrm dt=\sqrt{x^3-1}$

Now the arc length over an arbitrary interval $(a,b)$ is

$\displaystyle\int_a^b\sqrt{1+\left(\frac{\mathrm dy}{\mathrm dx}\right)^2}\,\mathrm dx=\int_a^b\sqrt{1+x^3-1}\,\mathrm dx=\int_a^bx^{3/2}\,\mathrm dx$

But before we compute the integral, first we need to make sure the integrand exists over it. $x^{3/2}$ is undefined if $x$ , so we assume $a\ge0$ and for convenience that $a$ . Then

$\displaystyle\int_a^bx^{3/2}\,\mathrm dx=\frac25x^{5/2}\bigg|_{x=a}^{x=b}=\frac25\left(b^{5/2}-a^{5/2}\right)$
