Answer:

1.5 as fraction it is  3/2 in simplest form

Step-by-step explanation:

The simplest form of the expression given is 3/2

A mathematical statement containing variables, numbers and connected by a mathematical operator is called an expression.

Given that, an expression  [tex]4\frac{1}{5}[/tex]  × [tex]\frac{5}{14}[/tex]

We are asked to simplify them,

[tex]4\frac{1}{5}[/tex]  × [tex]\frac{5}{14}[/tex]

= 21 / 5 × 5 / 14

= 21 / 14

= 3/2

Hence, the simplest form of the expression given is 3/2

Answer:

2          1/2  

Step-by-step explanation:

The roots are located on a circle with a center at the origin and a radius of 4. The arguments of two successive roots differ by (1/2)π units along the circumference of a circle.

The circumference of a circle is defined as the product of the diameter of the circle and pi.

The 4th roots of 16[cos(π) + i sin(π)] are the 4th roots of -16i. These roots are located on a circle with a center at the origin and a radius of 4 because the 4th roots of a complex number are equally spaced on a circle with a radius equal to the absolute value of the complex number.

The arguments of two successive roots differ by π/2 units along the circumference of a circle. This is because there are 4 roots and the circle has a circumference of 2π, so each root is spaced 2π/4 = π/2 units apart along the circumference of the circle.

For example, the first root is located at (4, 0) on the complex plane, which corresponds to an argument of 0.

The second root is located at (0, 4) on the complex plane, which corresponds to an argument of π/2.

The third root is located at (-4, 0) on the complex plane, which corresponds to an argument of π.

The fourth root is located at (0, -4) on the complex plane, which corresponds to an argument of 3π/2.

Thus, you can see that the arguments of the roots differ by π/2 units.

Answer:

This is the subtraction method

Y -3X = -10

(-Y -2x = -5)  -Y + 2X = 5

Y -3X = -10

-Y + 2X = 5

      -X = -5

X = 5  Now fill in the 5 for X and Y =  5

Answer:

x = 5, y = 5

or

(5, 5)

Step-by-step explanation:

they both equal y so they also equal each other.

3x - 10 = 2x - 5

3x - 2x = -5 + 10

x = 5

substitute x for 5

y = 3x - 10

y = 15 - 10

y = 5

edit, whops forgot to check

just plug the variables in with their values and see if it makes sense:

y = 2x - 5

5 = 2*5 - 5

5 = 10 - 5

5 = 5

since 5 does equal 5, the solution is correct.

Answer:

i)    [tex]cosec0 = \frac{hypotenuse}{opposite side} = \frac{53}{45}[/tex]

ii)   [tex]sec0 = \frac{hypotenuse}{adjacent side} = \frac{53}{28}[/tex]

Step-by-step explanation:

Step(i):-

Given that    

                 [tex]cot 0 = \frac{28}{45} = \frac{adjacentside}{opposite side}[/tex]

Hypotenuse AC² = AB²+BC²

    ⇒             AC² = 45²+28² = 2809

   ⇒             AC = √2809

 ⇒              AC = 53

Hypotenuse  AC =53

Step(ii):-

i)    [tex]cosec0 = \frac{hypotenuse}{opposite side} = \frac{53}{45}[/tex]

ii)   [tex]sec0 = \frac{hypotenuse}{adjacent side} = \frac{53}{28}[/tex]

Step-by-step explanation:

First question already answered in other post.

Second Question:

Original price before discount and tax: $354

Discount: 15%

100% - 15% = 85% = 0.85

0.85 * $354 = $300.90

Tax: 7.8%

100% + 7.8% = 107.8% = 1.078

1.078 * $300.90 = $323.37

Answer: $324.37

Answer:

the original price is 545$

Step-by-step explanation:

299.75$ : 55$ = x : 100

55x = 299.75 x 100

180

Step-by-step explanation:

180 * .2 = 36

20% is the same thing as 1/5 of something, so read the question again,

"36 is 1/5 of what number?"

Multiply 36 by 5 to get 180

Double check yourself by finding 20% of 180

Answer:

∠A = 62°

Step-by-step explanation:

∠ACB = 180 - 116 = 64°

∠A + ∠B + ∠C = 180°

(3x - 13) + (2x + 4) + 64 = 180°

3x + 2x - 13 + 4 + 64 = 180°

5x + 55 = 180°

5x = 180 - 55

5x = 125

x = 125/5

x = 25

∠A = 3x - 13

∠A = 3(25) - 13

∠A = 75 - 13

∠A = 62°

Answer:

Number of guests = 10

Step-by-step explanation:

Given that:

Caterer A charges $15 per person and $100 to set up tables. Caterer B charges $20 per person and $50 to set up tables.

Let,

x be the number of guests.

A(x) = 15x + 100

B(x) = 20x + 50

For the cost to be equal;

A(x) = B(x)

15x + 100 = 20x + 50

100 - 50 = 20x - 15x

50 = 5x

Dividing both sides by 5

[tex]\frac{5x}{5}=\frac{50}{5}\\x=10[/tex]

Hence,

Number of guests = 10
