Answer:

819,200

Step-by-step explanation:

First start by raising all the numbers to the power indicated:

5^4 = 625

8^5 = 32768

2^9 = 512

5^2 = 25

Then divide the numerators by the denominators:

625 / 8 = 78.125

32768 / 64 = 512

512 / 25 = 20.48

Finally, multiply all the numbers together

78.125 * 512 * 20.48 = 819200

Answer: sin(60°)= [tex]\frac{\sqrt{3}} 2[/tex] and cos(60°)=[tex]\frac{1} 2[/tex]

Step-by-step explanation:

sine means opposite/hypothenus (SOH)

opposite=[tex]\frac{\sqrt{3}} 2[/tex] and hypothenus is 1

sin(60°) = [tex]\frac{\sqrt{3}} 2[/tex] ÷ [tex]\frac{1} 1[/tex]

              =  [tex]\frac{\sqrt{3}} 2[/tex] × [tex]\frac{1} 1[/tex]

              =  [tex]\frac{\sqrt{3}} 2[/tex]

cosine means adjacent/hypothenus (CAH)

adjacent= [tex]\frac{1} 2[/tex] and hypothenus is 1

cos(60°) =  [tex]\frac{1} 2\\[/tex] ÷ [tex]\frac{1} 1[/tex]

              =  [tex]\frac{1} 2[/tex] × [tex]\frac{1} 1[/tex]

Answer:

[tex] \frac{ - 5}{4} [/tex]

Step-by-step explanation:

[tex] \frac{5}{6} \div \frac{ - 2}{3} [/tex]

When dividing two fractions, we turn the second fraction upside-down and multiply two expressions instead.

[tex] \frac{5}{6} \times \frac{ - 3}{2} = \frac{ - 15}{12} [/tex]

Now simplify the fraction by dividing it with biggest common divisor which is 3 in this case.

[tex] \frac{ - 5}{4} [/tex]

is the final result.

Answer:

ikj

Step-by-step explanation:

In a triangle:

When labeling angles and sides of triangles, it is convention to label the side opposite an angle with the same letter but in lower case.  

Therefore in ∆JLK:

As 16 < 73 < 91

⇒ m∠I < m∠K < m∠J

As the angles of ∆JLK in order from smallest to largest are IKJ, then the sides of ∆JLK in order from smallest to largest are ikj.

The required equation for sharing the bills equally is 5x = 62.65 and each will pay $12.53

How many friends went to the restaurant altogether?

The fact that the person went with  4 friends and paid for every means that he made payments for the 5 of them and he is expected to get refund from 4 persons, in other words, in order to share bills equally, the 5 friends would have to contribute equally, which means we would divided total bills by the number of friends, which is 5 not 4 because the first person would also his part of the bills

Let x be the amount paid person, the total amount paid would be x paid person multiplied by the number of friends, 5

total amount paid=5*x

total amount paid =5x

the amount paid in dollars is $62.65

5x=62.65

So nearest hundred of calories of pizza is 3384.

As it is given that its an pizza of 16 inches .

A Calorie is unit of heat used to indicate the amount of energy foods produce in the human body that is equal to 1000 calories.

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80.

So as we all know pizza of 16 inches contains 3384.00 calories

The total number of people in the food court eating pizza, burritos, and hamburgers is 113 (Approximate) or (Whole number)

People eating hamburger P(h) =0.38

People eating burritos P(b) = 0.31

Number of people eating pizza = 35

    Let's suppose the total number of people is 1

So,

    By adding the total number of people eating hamburgers and burritos                                          

                                                           = 0.38+0.31

                                                            = 0.69

    The ratio of the total number of people eating pizza = 1.00 - 0.69

                                                                                            = 0.31

   So total number of people eating pizza = 0.31 = 35

   By solving :

              1 = 35 / 0.31

                = (35*100)/31

Answer:

x = 7, x = 10

Step-by-step explanation:

x² + 70 = 17x ( subtract 17x from both sides )

x² - 17x + 70 = 0 ← in standard form

consider the factors of the constant term (+ 70) which sum to give the coefficient of the x- term (- 17)

the factors are - 10 and - 7 , since

- 10 × - 7 = + 70 and - 10 - 7 = - 17 , then

(x - 10)(x - 7) = 0 ← in factored form

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x - 10 = 0 ⇒ x = 10

Step-by-step explanation:

The equation of the parabola is (x - 6)² = 6(y + 5.5).

Given that, a focus at (6,-4) and a directrix at y= -7.

We need to find the equation for a parabola.

Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).

The standard form of the equation of the parabola is  (x - h)² = 4p(y - k), where

The vertex of the parabola is (h , k)

The focus is (h, k + p)

The directrix is at y = k - p  

∵ The focus of the parabola is at (6, -4)

The coordinates of the focus are (h, k + p)

∴ h = 6

∴ k + p = -4 ⇒ (1)

∵ The directrix of the parabola is at y = -7

The directrix is at y = k - p

∴ k - p = -7 ⇒ (2)

Solve the system of equations to find k and p

Add equations (1) and (2) to eliminate p

∴ 2k = -11

Divide both sides

∴ k = -5.5

Substitute the value of k in equation (1) to find p

∵ -5.5 + p = -4

Add 5.5. to both sides

∴ p = 1.5

∵ The form of the equation is (x - h)² = 4p(y - k)

Substitute the values of h, k, and p in the form

∴ (x - 6)² = 4(1.5)(y - -5.5)

∴ (x - 6)² = 6(y + 5.5)

Therefore, the equation of the parabola is (x - 6)² = 6(y + 5.5).

Answer:

Circumference = 75.4

Step-by-step explanation:

Since the circles are identical, that means that the radii must be equal.

4x=3x+3

x=3

That means that radius = 12

The formula for the circumference = 2pi × radius

2pi × 12 = 24pi ≈ 75.4

Answer:

75.4 (nearest tenth)

Step-by-step explanation:

The diameter of a circle is the distance from one side of the circle to the other through the center. The diameter is the widest part of the circle.

The radius of a circle is the distance from the center to the circumference.  The radius is half the diameter of a circle.

We have been given the radius of the circle on the left:  r = 4x.

Therefore, as the diameter is twice the radius, the diameter of the circle on the left is:  d = 2(4x) = 8x

We have been given the diameter of the circle on the right:  d = 6x + 6

Equate the two diameters and solve for x:

⇒ 8x = 6x + 6

⇒ 8x - 6x = 6x + 6 - 6x

⇒ 2x = 6

⇒ 2x ÷ 2 = 6 ÷ 2

⇒ x = 3

Substitute the found value of x into one of the diameter expressions to find the diameter of both circles:

⇒ d = 8x

⇒ d = 8(3)

⇒ d = 24

Circumference of a circle

C = πd

(where d is the diameter)

Substitute the found diameter into the circumference formula:

⇒ C = πd

⇒ C = 24π

⇒ C = 75.39822...

⇒ C = 75.4 (nearest tenth)

Therefore, the circumference of each circle is 75.4 units (nearest tenth).
