Answer:

13)  \frac{3m}{2n^2} (answer (C))

14)  \frac{4b}{3} (answer (A))

Step-by-step explanation:

Problem 13)

Cancel  out in PAIRS the common factors in numerator and denominator

\frac{3m^4n^2}{2m^3n^4} =\frac{3m}{2n^2}

which agrees with answer C

Problem 14)

Cancel  out in PAIRS the common factors in numerator and denominator

\frac{4a^2b^2}{3ba^2} =\frac{4b}{3}

which agrees with answer A

Find the component form for vector AB given the initial point A (1, 7, -9) and terminal point B (-2, 18, 4).
Tanzania [10]

To find each of the components of AB we can find the different between the components on the terminal and initial points, doing that, we find:

AB = (-2 - 1, 18 -7, 4 - (-9)) = (-3, 11, 13).

An item is sold for £305. If this includes a mark up of 7%. Find the buying in price
Lady_Fox [76]

Answer:

Let the original price be 'x'

7/100 * x + x = 305

(7x+100x)/100 = 305

107x = 305 * 100

107x= 30500

x= 30500/107

x= 285.04

Therefore, the original buying price is £ 285.04

Hope you understood......

A movie theater earned $3,600 in sold-out ticket sales for the premiere of a new movie. VIP tickets cost $20 per person and regu
julia-pushkina [17]

There are 300 seats in the theater.

Step-by-step explanation:

Given,

Cost of one VIP ticket = $20

Cost of one regular ticket = $8

Worth of sold out tickets = $3600

Let,

x represent the number of VIP tickets sold

y represent the number of regular tickets sold

20x+8y=3600     Eqn 1

y = 2x                   Eqn 2

Putting value of y from Eqn 2 in Eqn 1

20x+8(2x)=3600\\20x+16x=3600\\36x=3600

Dividing both sides by 36

\frac{36x}{36}=\frac{3600}{36}\\x=100

Putting x=100 in Eqn 2

y=2(100)\\y=200

Total = x+y = 100+200 = 300

There are 300 seats in the theater.
