Draw the vector C⃗ =A⃗ +2B⃗ . The drawing is attached below

<h3>Further explanation </h3>

Vector is a quantity that has a value and direction. It can be symbolized in the form of directed line segments. Operations on vectors include addition and subtraction.

In the drawing, vector B seems to be (1, 108 degrees) and vector A seems to be (4, 0 degrees) in the drawing.

a + b = c

Where If vector a is added by inverse b (-b) then the sum becomes a + (- b) = a-b

If we multiply vector A by 1 then the length becomes 1 times vector A and in the same direction, so does vector B multiplied by the value of +2, which is 2 times the length of vector B in the same the direction as vector A, so we get vector C (attached picture) obtained by drawing a line from the starting point A and the endpoint B

Let the number of minutes be = x.

Cost per minute = 11 cents = 0.11

Phone Bill = Monthly fee  +    0.11* x 

Substituting from the question

20.82 = 3 + 0.11x

3 + 0.11x = 20.82

0.11x = 20.82 - 3

0.11x = 17.82

x = 17.82/0.11

x = 162

a certain test is worth 135 points. how many points (rounded to the nearest point) are needed to obtain a score of 85%?
yanalaym [24]

To obtain a score of 85% on a test worth 135 points, one needs to get 115 points. By using proportions, we get the required value.

<h3>How to write proportions?</h3>

A proportion is defined as an equality between two ratios.

Consider two ratios a:b and c:d. Then, the proportion we can write,

a: b = c : d

Then, the simplification we have for this proportion is

a/b = c/d or ad = bc

<h3>Calculation:</h3>

It is given that, a certain test is worth 135 points.

One to get 85% on this test, he/she needs to get X number of points.

So, we can write the proportions as

X : 135 = 85 : 100

⇒ X/135 = 85/100

⇒ X = 85/100 × 135

∴ X = 114.75 ≅ 115 points
