We want a unit rate where

1 is in the denominator

so we divide top and bottom by 20

[tex]\frac{400 miles/20}{20 gallons/20}[/tex]  = [tex]\frac{20 miles}{1 gallon}[/tex] = 20 miles a gallon

Answer:

Please read below.

Step-by-step explanation:

P(event)= favorable outcomes / total outcomes

0.84 * 100 = 84

100 - 84 = 16

84 favorable outcomes

16 unfavorable outcomes

100 total outcomes

Therefore there is a 84% chance of it happening.

Therefore there is a 16% chance of it not happening.

P(event) = 84/100

8.4 out of 10

Describe it how ever you want. 8.4 out of 10 is a pretty good bet to me. I would put my money on it. There isn't a lot of context to the question. But, I hope this helps!

It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.

Probability is to measure the occurrence of an event.

It is given that

probability of an event = 84% or 0.84

This means, P(E) = 0.84

Number of favorable outcomes/ Total outcomes =84

Let us say Total outcomes are 1000

So favorable outcomes = 1000*0.84

Favorable outcomes = 840

Therefore, It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.

Step-by-step explanation:

===================================================

Explanations:

Problem 1

v = 9i - 4j means we move 9 units to the right and 4 units down.

Another way to write this is v = <9, -4>

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

Problem 2

R = (-19, 6)

S = (-35, 13)

Subtract x coordinates:  xS - xR = -35 - (-19) = -16

Subtract y coordinates: yS - yR = 13 - 6 = 7

Those results form the vector v = -16i + 7j

This vector indicates we move 16 units left and 7 units up when going from point R(-19,6) to point S(-35,13).

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

Problem 3

t = -5i + 12j

||t|| = sqrt( (-5)^2 + (12)^2 )

||t|| = 13

theta = arctan(12/(-5))

theta = -67.38

Add on 180 to get to the proper quadrant Q2

-67.38 + 180 = 112.62

Therefore,

[tex]t = 13\bigg\langle \cos(112.62^{\circ}), \ \sin(112.62^{\circ})\bigg\rangle[/tex]

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

Problem 4

The x, y components are the coefficients of the linear form.

This allows us to go immediately from <-39,16> to -39i + 16j

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

Problem 5

P = (-5,11)

Q = (-16,4)

Subtract x coords: xQ - xP = -16 - (-5) = -11

Subtract y coords: yQ - yP = 4 - 11 = -7

The component form of vector t is <-11, -7> and this vector is in Q3.

r = sqrt(a^2 + b^2)

r = sqrt( (-11)^2 + (-7)^2 )

r = 13.038 is the approximate length of the vector.

theta = arctan(b/a)

theta = arctan(-7/(-11))

theta = 32.471

Add on 180 so we get to Q3

32.471+180 = 212.471

Therefore, we have

[tex]x = r\cos(\theta) = 13.038\cos(212.471^{\circ})\\\\y = r\sin(\theta) = 13.038\sin(212.471^{\circ})\\\\t = xi + yj\\\\t = 13.038\cos(212.471^{\circ})*i + 13.038\sin(212.471^{\circ})*j\\\\[/tex]

in which you could write into this slightly more compact form

[tex]t = 13.038\bigg\langle\cos(212.471^{\circ}),\sin(212.471^{\circ})\bigg\rangle\\\\[/tex]

Answer:

28687.5

Step-by-step explanation:

Un gramo equivale a $38,25, por lo que si tenemos 750 de esos gramos, tendríamos que multiplicarlos para obtener el costo total.

By comparing the figure with simpler shapes (rectangles and triangles) we will see that its area is 30ft^2.

The area of the figure will be equal to the difference between the area of a 5ft by 10 ft rectangle, and the area of the 3 triangles that can be formed.

The area of a 5ft by 10ft rectangle is:

A = 5ft*10ft = 50ft^2

For the 3 triangles we have:

2 triangles with a base of 5ft - 3ft = 2ft, and a height of 10ft/2 = 5ft.

(these are the two left triangles).

Remember that for a triangle of base b and height h, the area:

A = b*h/2

Then for each of these triangles, the area is:

A' = (2ft*5ft)/2 = 5ft^2

And we have two of these, so the areas add up to 10ft^2.

For the right triangle, we can see that its base measures 10 ft, and its height is of 2 ft, then its area is:

A'' = (10ft*2ft)/2 = 10ft^2

Then the area of the figure is:

Area = A - 2A' - A'' = 50ft^2 - 2*(5ft^2) - 10ft^2 = 30ft^2

In conclusion:

Option C is correct.

Solution:

Note that:

Simplify the equation to find x.

Add 10 both sides.

Subtract 3x both sides.

Divide 3 both sides.

Answer:

Step-by-step explanation:

opposite angles = equal angles

we solve with a proportion

3x + 50 = 6x - 10

50 + 10 = 6x - 3x

60 = 3x

x = 60 : 3

x = 20
