Convert any mixed numbers to fractions.
Then your initial equation becomes:

Applying the fractions formula for subtraction,

here is the gauge for the fuel tank of a car.the tank holds 68 litres when the tank is full. the tank is 1/4 full of fuel work o

MrRissso [65]

Answer:

51 liters of fuel is needed more to fill the tank

Step-by-step explanation:

When the gauge is full, the volume of fuel in the tank is 68 liters.

Now it is 1/4 full.

The amount of fuel it has when it is 1/4 full would be 1/4 * 68 = 17 liters

Now, we need to know how many more liters of fuel until the tank is full.

What we just need to do here is to subtract the volume when it is quarter full from the volume when it is full.

That would be 68 liters - 17 liters = 51 liters

Vector v is shown in the graph.

Elis [28]

Question 4

<h3>Answer: Choice D</h3>

Explanation:

If the initial point is the origin, the coordinates of the terminal point form the vector itself in component form. We go from (-8,6) to <-8,6>. The notation change is from ordered pair to vector format.

We have a right triangle with legs of 8 and 6 units. The pythagorean theorem will help us determine the hypotenuse is 10. Therefore, the vector length is 10 units and we would say ||v|| = 10. We have a 6-8-10 right triangle.

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

Question 5

<h3>Answer: Choice B</h3>

Explanation:

Vector v starts at (2,5) and ends at (-3,-2).

The x component of the vector is x2-x1 = -3-2 = -5 meaning we move 5 units to the left when going from the start point to the endpoint.

At the same time we move 7 units down because y2-y1 = -2-5 = -7 which is the y component of the vector.

The component form of vector v is

v = <-5, -7>

it says "move 5 units left, 7 units down".

Apply the pythagorean theorem to find the length of the vector.

a^2+b^2 = c^2

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

||v|| = sqrt( (-5)^2 + (-7)^2 )

||v|| = 8.602 which is approximate.

Now let's use the arctangent function to find the angle

theta = arctan(b/a)

theta = arctan(-7/(-5))

theta = 54.462 which is also approximate.

There's a problem however. This angle is in Q1 but the vector <-5,-7> is in Q3. An easy fix is to add on 180 to rotate to the proper quadrant.

54.462+180 = 234.462

which is the proper approximate angle for theta.

An insurance policy pays 80% of the first $20,000 of a patient's medical expenses, and 60% of the remainder. If the patient's to

lana [24]

Answer:

The policy pay $47200 .

Step-by-step explanation:

As given

An insurance policy pays 80% of the first $20,000 of a patient's medical expenses, and 60% of the remainder.

80% is written in the decimal form.

$= \frac{80}{100}$

= 0.80

Medical expenses pay by the insurance policy on first $20000 = 0.80 × 20000

= $16000

As given

Insurance policy pays 60% of the remainder.

The patient's total medical bill is $72,000.

Patient medical bill over $20000 = $72000 - $20000

=$52000

60% is written in the decimal form.

$= \frac{60}{100}$

= 0.60

Medical expenses pay by the insurance policy on the remainder = 0.60 × $52000

= $31200

Total Medical expenses pay by the insurance policy = Medical expenses pay by the insurance policy on first $20000 + Medical expenses pay by the insurance policy on the remainder .

Total Medical expenses pay by the insurance policy = $16000 + $31200

= $47200

Therefore the policy pay $47200 .
