Answer:

This vector make an angle of 141° with the positive x axis

Step-by-step explanation:

Refer the attached figure

Components of vector :

[tex]A_x=-10 \\A_y = 8[/tex]

We are supposed to find  What angle does this vector make with the positive x axis

[tex]tan \theta =\frac{A_y}{A_x}\\tan \theta =\frac{8}{-10}\\\theta =tan^{-1}(\frac{8}{-10})\\\theta =tan^{-1}(\frac{8}{-10})=-38.65^{\circ}[/tex]

Now ,

[tex]\alpha = 180-38.65=141.35^{\circ}[/tex]

So, this vector make an angle of 141° with the positive x axis

Answer:

50 cent

Step-by-step explanation:

Given that :

Cost of energy = $0.068 per kilowatt-hour (kWh)

Number of bulbs = two 10 watt bulbs

Converting the power of the bulb to kilowatt :

2 * 10watt = 20 watt

1000 watt = 1 kilowatt

20 watt = x

1000x = 20

x = 20/1000

x = 0.02 kW

Cost of Energy consumed by bulb 1 hour for 365 days :

0.02kW * 1 * 365 * $0.068 = $0.4964

$0.4964 to cent

100 cent = $1

$0.4964 * 100 = 49.64 cent

49.64 = 50 (nearest cent)

Answer:

x=30

Step-by-step explanation:

since it is a equilateral triangle, every angle is 60.

so 180-60=120, thus giving how much 5x-30 is.

5x-30=120

150=5x

30=x

Answer:

0-9 gives you 10 possibilites.

10x10x10x10x10=100,000

Step-by-step explanation:

A lottery game called Quinto is played by choosing five numbers each, from 0 through 9,  there are 10 possibilities

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that  lottery game called Quinto is played by choosing five numbers each, from 0 through 9

Therefore, we are asked to find the number of possibilities.

10 x 10 x 10 x 10 x 10

=100,000

Thus, there are 100,000 number

This means that from 0 through 9 there are 10 possibilities.

Hence, A lottery game called Quinto is played by choosing five numbers each, from 0 through 9,  there are 10 possibilities

Answer:

Its True

Step-by-step explanation:

Just put in False and got it wrong.

Answer: 0.9147

Step-by-step explanation:

Given: 20% of the plants ordered are petunias.

Let p = 20% = 0.2

Sample size: n = 120

If they follow normal distribution, then mean = np = 120x 0.2 = 24

Standard deviation = [tex]\sqrt{n p(1-p)}=\sqrt{120\times0.2\times.8}[/tex]

[tex]=\sqrt{19.2}\\\\ =4.38[/tex]

The  probability that no more than 30 plants are petunias : [tex]P(\dfrac{X-\mu}{\sigma}\leq \dfrac{30-24}{4.38})[/tex]

[tex]=P(Z<1.37)= 0.9147[/tex]

Hence, the probability that no more than 30 plants are petunias = 0.9147

Answer:

m = 45/7

Step-by-step explanation:

move terms :

49 - 3m - 4m = 4

-3m - 4m = 4 - 49

collect like terms

-7m = 4 - 49

-7 = -45

divide both sides of the equation by -7

= m = 45/7

Answer:

m = 6.43

Step-by-step explanation:

49 - 3m = 4m + 4

1. subtract 4 from both sides

  45 - 3m = 4m

2. add 3m to both sides

  45 = 7m

3. divide by 7

  6.428571429 = m

4. round to nearest hundreths

   6.43

Answer:

The answer is x^2y^-12

The simplified form of the expression  (xy⁻⁶)² is  x²/y¹².

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

Given, An expression (xy⁻⁶)².

= (x²y⁻¹²).      (as the exponent of exponent multiply).

Answer:

123.8 units

Step-by-step explanation:

The vertices of the polygon has been labelled ABCDEF, as shown in the diagram attached below.

Perimeter of the Polygon = [tex] \overline{AB} + \overline{BC} + \overline{CD} + \overline{DE} + \overline{EF} + \overline{FA} [/tex]

[tex] \overline{AB} [/tex] = |-12 - 24| = |-36| = 36 units

[tex] \overline{BC} [/tex]: calculate the distance between B(24, 16) and C(15, 3) using the distance formula.

[tex] \overline{BC} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] \overline{BC} = \sqrt{(24 - 15)^2 + (16 - 3)^2} [/tex]

[tex] \overline{BC} = \sqrt{(9)^2 + (13)^2} [/tex]

[tex] \overline{BC} = \sqrt{81 + 169} = \sqrt{250} [/tex]

[tex] \overline{BC} = 15.8 units [/tex]

[tex] \overline{CD} [/tex] = |6 - 15| = |-9| = 9 units

[tex] \overline{DE} [/tex] = |3 -(-12)| = |-15| = 15 units

[tex] \overline{EF} [/tex] = |-12 - 6| = |-18| = 18 units

[tex] \overline{FA} [/tex] = |18 -(-12)| = 30 units

Perimeter = 36 + 15.8 + 9 + 15 + 18 + 30 = 123.8 units

Answer:

147 yards

Step-by-step explanation:

Use a system of equations

Let x be length of rectangle and y be width of rectangle

x = 3y

2x + 2y = 56

Substitute x = 3y into second equation, we have 2(3y) + 2y = 56. Combine like terms and we have 8y = 56. y = 7.

Substituting y = 7 into the first equation, we have x = 3(7), and x = 21.

Area is length times width, so area is 21 * 7 = 147

Answer:

area= 147 yd

Step-by-step explanation:

l= 21 yd

w= 7 yd

Formula: a=lxw (area=length x width)

a=21 x 7

21 x 7=147 yd

Here we want an integer that can be inserted into the blank.

We have:

-15 , -3 4/5 , -1.5 , blank , 2.3 , 5 2/3

The integer that must be inserted into the blank should have a value between -1.5 and 2.3

What this means is that it should be greater than -1.5 but less than 2.3

Option A is incorrect since -2 itself is less than -1.5

Answer:

132

Step-by-step explanation:

First, find how many beats are in a minute by creating a proportion:

[tex]\frac{11}{5}[/tex] = [tex]\frac{x}{60}[/tex]

Cross multiply and solve for x:

5x = 660

x = 132

So, there are 132 beats in one minute.

This means the constant of proportionality is 132.

The proportional relation is y= 2.2x

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Neena counts 11 beats in 5 seconds

So, x=11 and y=5

Using the proportionality

y = k x

k= y/x

k= 11/5

k= 2.2

Hence, the proportional relation is y= 2.2x
