Answer:

y * 184 = 395

Step-by-step explanation:

Answer:

184y = 395 should be the answer

Step-by-step explanation:

Answer:

17.5

Step-by-step explanation:

formula:

y=k(x)

direct variation^^^

y=7, x=2

substitute it in the formula

7=(k)2 or 7=2k

7/2 or 3.5= k, k is the constant

now substitute k to the problem

y=5k

y=5(3.5)

y=17.5

Answer:

the answer is (2•5x5y3)

Step-by-step explanation:

1.  (2x4 • y3) • 5x

Multiplying exponential expressions

2. x4 multiplied by x1 = x(4 + 1) = x5

Final result :

(2•5x5y3)

Answer:

[tex]\sqrt{135\\}[/tex]

Step-by-step explanation:

Geometric mean can be calculated like such:

a/x = x/b

Where a and b are your 2 numbers. By solving for x by cross-multiplying you get:

x^2=ab

So to solve for geometric mean, all you have to do is to multiply the two numbers and take the square root:

9(15)=135

[tex]\sqrt{135\\}[/tex]

The geometric mean of 9 and 15 is 11.62

Given two integers A and B, the geometric mean of the integers is expressed as:

GM = √A×B

Given the values 9 and 15, the geometric mean of the values is expressed as:

GM = √9×15

GM = √135

GM = 11.62

Hence the geometric mean of 9 and 15 is 11.62

Answer:

$480

Step-by-step explanation:

Assuming that you have worked 10 hours and have done 3 policies in the equation 18h+100p, you want to plug in the said hours and policies into the variables to get this 18 (10) + 100 (3).  You should get $480 as a result.

Answer:

113

Step-by-step explanation:

The area is π[tex]r^{2}[/tex], and pi is about 3. r is d/2 which is 12/2=6.

6^2 is 36 and 36*3 = 108. 113 is the closest, so that is the best estimate.

Answer:

[tex]x=\dfrac{8}{\sqrt3}[/tex]

Step-by-step explanation:

Given that,

[tex]\sin(30)=\dfrac{\dfrac{4}{\sqrt3}}{x}[/tex] ...(1)

We need to find the value of x.

We know that,

sin30 = 1/2

Use it in equation (1).

[tex]\dfrac{1}{2}=\dfrac{\dfrac{4}{\sqrt3}}{x}\\\\x=\dfrac{4}{\sqrt3}\times 2\\\\x=\dfrac{8}{\sqrt3}[/tex]

So, the value of x is equal to [tex]\dfrac{8}{\sqrt3}[/tex].

Answer:

$3.25

Step-by-step explanation:

The grapes costs $2.70 per pound but you're buying 2.5 pounds so take $2.70 x 2.5 = $6.75. Now u just take $10 - $6.75 which equals $3.25 and thats ur answer.

Answer:

You receive 3.25 cash back.

Step-by-step explanation:

2.70 x 2.5 = 6.75

6.75 + ? = 10

A = 3.25

Answer:

-937.5 mph

Step-by-step explanation:

Assuming this takes place in a right angled triangle. With the hypotenuse side being, d, 15 miles, the opposite side being 9 miles and the adjacent being an unknown, x.

Using Pythagoras theorem, we know that

x² = 15² - 9²

x² = 225 - 81

x² = 144

x = √144

x = 12 miles.

Again, we should know that

2xx' = 2dd', this means that

xx' = dd'

From the question, we're told that it's decreasing at d' = 750 mph. On substituting, we have

x' = dd' / x

x' = (15 * -750) / 12

x' = -11250 / 12

x' = -937.5 mile per hour

The ground speed of the plane is also decreasing at 937.5 mile per hour

Step-by-step explanation:

The break-even point is on both curves. The y-intercept can be used for the other point in each case.

The break-even point is where cost and revenue are the same:

 20/3x +50 = 10x

 50 = 10/3x . . . . . . . . subtract 20/3x

 15 = x . . . . . multiply by 3/10

 r = c = 10(15) = 150 . . . . for x = 10

Two points you can use for graphing the lines are ...

 cost: (0, 50) and (15, 150)

 revenue: (0, 0) and (15, 150)

9514 1404 393

Answer:

  6

Step-by-step explanation:

Cost and revenue are equal when ...

  C = R

  2.5x +21 = 6x

  21 = 3.5x . . . . . . subtract 2.5x

  6 = x . . . . . . . . . .divide by 3.5

The company must sell 6 items to break even.

Step-by-step explanation:

Theres a formula to figure this out. If you know two sides of a right angle triangle you can find the third.

Use the formula a²=b²+c², where a is the side opposite the right angle and b and c are the other sides.

a²=b²+c²

7²=2²+c²

49=4+c²

49-4=c²
