Answer:

Step-by-step explanation:

A parallelogram also has the following properties:

Opposite angles are congruent;

Opposite sides are congruent;

Adjacent angles are supplementary;

The diagonals bisect each other.

Notice that v points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.

The factor of 1/√80 comes from normalizing the vector v. Its norm/magnitude is

|v| = √((-4)² + (-8)²) = √(16 + 64) = √80

so the unit vector that points in the same direction as v is simply v / |v|.

Answer:

3/4 cm^3

Step-by-step explanation:

Volume = base area * height. Where base area is 1/2*1/2 (As it is a square) and height = 3 cm, so times together get 3/4.

Step-by-step explanation:

multiply them all

V=h×l×w

V=½cm × 3cm × ½cm

V=¾cm³

Answer:

Cost of article before tax is 120.

Step-by-step explanation:

It says cost of an article including 15% tax is 138.

So, let the cost of article without tax as 'x'

So, we can set up equation as

x+15%(x)=138

Simplify it

x+0.15x=138

1.15x=138

Divide both sides by 1.15

x=120

So, cost of article before tax is 120.

Answer:

80.45 inches

Step-by-step explanation:

Last year Stevie was 281/4 inches tall, which is: 70.25 inches (70 1/4)

He has grown 51/5 inches which is: 10.2 inches (10 1/5)

70.25 inches (last years height) + 10.2 inches (how many he has grown) = 80.45 inches

Stevie is 80.45 inches tall now.

Answer:

(9 1/2) * (19 1/4) = 1463/8 = 182 7/8

Step-by-step explanation:

Conversion a mixed number 9 1/2

to a improper fraction: 9 1/2 = 9 1/2

= 9 · 2 + 1/2

= 18 + 1/2

= 19/2

To find a new numerator:

a) Multiply the whole number 9 by the denominator 2. Whole number 9 equally 9 * 2/2

= 18/2

b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19

c) Write a previous answer (new numerator 19) over the denominator 2.

Nine and one half is nineteen halves

Conversion a mixed number 19 1/4

to a improper fraction: 19 1/4 = 19 1/4

= 19 · 4 + 1/4

= 76 + 1/4

= 77/4

To find new numerator:

a) Multiply the whole number 19 by the denominator 4. Whole number 19 equally 19 * 4/4

= 76/4

b) Add the answer from previous step 76 to the numerator 1. New numerator is 76 + 1 = 77

c) Write a previous answer (new numerator 77) over the denominator 4.

Nineteen and one quarter is seventy-seven quarters

Multiple: 19/2

* 77/4

= 19 · 77/2.4

= 1463/8

Answer:

26/x = 13

x = 2

Step-by-step explanation:

2(x - 4) = 4

2x - 8 = 4

2x = 4 + 8

2x = 12

x = 12/2

x = 6

26/x = 13

Cross product

26 = x * 13

26 = 13x

x = 26/13

x = 2

- 3.8x = -7.4

x = -7.4 / -3.8

x = 1.95

4(x - 1) - 3(x - 2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -8 - 2

x = -10

The value of given x is 16

Given that:

Perimeter of square = 76 cm

Side of square = (x + 3)

Find:

The value of x

Computation:

Perimeter of square = 4[Side]

76 = 4[x + 3]

76 = 4x + 12

4x = 76 - 12

4x = 64

x = 64 / 4

x = 16

The value of x = 16

Answer:

peri=3(3xsq-4x+9)

=9x^2-12x+27

Answer:

z = 9

Step-by-step explanation:

JH is a perpendicular bisector of Δ IJK.

Thus the triangle is isosceles with

JK = JI , that is

7z = z + 54 ( subtract z from both sides )

6z = 54 ( divide both sides by 6 )

z = 9

Answer: 305 people

Step-by-step explanation:

The total number of people sampled is:

= 71 + 22 + 27 + 83

= 209

Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:

= 71 + 27

= 98 people

In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:

= 98/ 209 * 650

= 305 people
