Answer: $38.50

Step-by-step explanation: Find 70% of $55.

Answer:

38.5

Step-by-step explanation:

SO U FIND 10% WHICH IS =5.5

AND THAT IS =38.5

The equivalent expression to (10 + 7r - r) + ( - 6r² - 18 + 5r) is

- 6r² + 11r - 8.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A quadratic expression (10 + 7r - r) + ( - 6r² - 18 + 5r).

First, we'll combine the like terms.

= - 6r² + 7r - r + 5r + 10 - 18.

Now, Writing the expression in descending power of 'r' we get,

= - 6r² + 11r - 8.

Q. Which expression is equivalent to (10 + 7r - r) + (-6r² -18 + 5r)?

Answer:

The value of function at X=4 is f(4) = 6.

Step-by-step explanation:

Given that:

Function is f(x) = x²-3x+2

A function defines the relationship between an independent variable and a dependent variable.

We have to find the value of function f(4), therefore, we will put x=4 in the given function

f(4) = (4)²-3(4)+2

f(4) = 16-12+2

f(4) = 6

Hence,

The value of function at X=4 is f(4) = 6.

The answer is $10 per adult ticket, and $7 per child ticket. Now lets figure out how to get to that answer. Let's create a chart to help visualize this.

- - - - -A- - - - - C- - - - -T- - - - -

    :     2    :      4     :   $48    :    

    :     5    :        2   :   $64    :                Key:

    :           :             :               :                      A = Adult ( The Y)

    :           :             :               :                      C = Child ( The X)

    :           :             :               :                       T= Total

When we look at it, the total cost is less then what the adult would be when multiplied by 10, and you WOULD have to add the children cost to the adult cost, so lets try it.

Lets do the 2 adult tickets first, 2 x 10 is 20. Now we do 48 - 20 to get how much the cost of the children's 4 needs to equal. We get 28 as the answer. Now we have to do 28 divided by 4, we get 7 as that answer.

Now lets plug that in to the $64 problem and see if that gets us the correct answer.

So the amount of adult tickets for this problem is 5, so we do 5 x 1 which is 50.

Now the amount of children tickets is 2, so lets do 2 x 7, which equals 14.

Now to test if it gets us the correct answer, to do that we do 50 + 14, that equals what we want it to, 64.

Therefor, the correct answer is $10 per adult ticket, and $7 per child ticket.

Hope this helps!

Answer:

Step-by-step explanation:

a). By applying tangent rule in the triangle,

   tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{3}{4}[/tex]

   θ = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]

   θ = 36.87°

   Therefore, θ < 45°

b). By using cosine rule in this triangle,

   cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}=\frac{18}{18\sqrt{2}}[/tex]

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

    θ = 45°

c). By using tangent rule,

  tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{8}{2}[/tex]

  θ = [tex]\text{tan}^{-1}(4)[/tex]

  θ = 75.96°

  θ > 45°

the reason it's because you only changed the Y intercept number to a negative so it will shift down the graph 14 units because if you have no adding number then your graph will start at 0 but it's -7 so it starts at -7 so now shift 14 places down

Answer:

The rate at which the radius is decreasing when the radius is 6 cm is approximately 3.316 × 10⁻³ cm/s

Step-by-step explanation:

The rate at which air is being lost from the balloon = 3/2 cm³/s

The rate at which the radius is decreasing when the radius is 6 cm long is given as follows;

The rate at which air is being lost from the balloon = dV/dt = 3/2 cm³/s

dV/dt = dV/dr × dr/dt

Where;

dr/dt = The rate at which the radius is decreasing

dV/dr = d(4/3×π×r³)/dr = 4·π·r²

Therefore, we have;

dr/dt = (dV//dt)/(dV/dr) = (3/2 cm³/s)/(4·π·r²)

dr/dt = (3/2 cm³/s)/(4·π·r²)

When r = 6 cm, we have;

dr/dt = (3/2 cm³/s)/(4 × π × (6 cm)²) ≈ 3.316 × 10⁻³ cm/s

Therefore, the rate at which the radius is decreasing, dr/dt, when the radius is 6 cm long ≈ 3.316 × 10⁻³ cm/s.
