Under her cell phone plan, Grace pays a flat cost of $70 per month and $4 per gigabyte. She wants to keep her bill at $74.40 per month. Write and solve an equation which can be used to determine xx, the number of gigabytes of data Grace can use while staying within her budget. i don´t understand how to set up the problem.

Answers

The equation of the cell phone plan is y = 70 + 4x and the number of gigabyte is 1.10

How to determine the equation?

The given parameters are:

Flat = $70 per month

Rate = $4 per gigabyte

Let the number of gigabyte be x, and the total cost be y.

So, we have:

y = Flat + Rate * x

So, we have:

y = 70 + 4x

When the bill is $74.40, we have:

74.40 = 70 + 4x

Subtract 70 from both sides

4x = 4.40

Divide both sides by 4

x = 1.10

Hence, the equation is y = 70 + 4x and the number of gigabyte is 1.10

A child flies a kite at a height of 90 ​ft, the wind carrying the kite horizontally away from the child at a rate of 30 ft/sec. How fast must the child let out the string when the kite is 150 ft away from the​ child?

Answers

By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

How to determine the rate of change of the string

The geometric representation of this question is based on the Pythagorean theorem:

l² = x² + y²     (1)

Where:

x - Horizontal distance of the kite from the kite, in feet.y - Height of the kine, in feet.l - Length of the string, in feet.

The rate of change of the length of the string is obtained by differential calculus:

[tex]2 \cdot l \cdot \dot l = 2\cdot x \cdot \dot x[/tex]

[tex]\dot l = \frac{x\cdot \dot x}{l}[/tex]

[tex]\dot l = \frac{x\cdot \dot x}{\sqrt{x^{2}+y^{2}}}[/tex]    (2)

If we know that x = 150 ft, y = 90 ft and [tex]\dot x = 30\,\frac{ft}{s}[/tex], then the rate of change of the length of the string is:

[tex]\dot l = \frac{(150\,ft) \cdot \left(30 \,\frac{ft}{s} \right)}{\sqrt{(150\,ft)^{2}+(90\,ft)^{2}}}[/tex]

[tex]\dot l \approx 25.725\,\frac{ft}{s}[/tex]

By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

The plane Avia flies holds 2900 gallons of fuel. She landed the plane this morning with a reserve of 900 gallons. The plane is refueled at a rate of 300 gallons of fuel per minute. The function h(x)=900+300x represents the amount of fuel in her plane after x minutes of refueling. What is the meaning of h(5.5) in the context of this situation?

Answers

Answer:

Is (-1,4) a solution to the graph of

y= 3x + 7?

EXPLAIN WHY OR WHY NOT

Answers

Answer:

True

Step-by-step explanation:

(-1,4) = (x,y)

This means if "x = -1, then y should be 4"

y = 3x + 7

y = 3(-1) + 7

y = -3 + 7

y = 4

It is saying if x is -1, y is 4. This statement of "Is (-1,4) a solution to the graph of "y = 3x + 7?" Is true. You can also graph this and find the point (-1,4) and it would be on the line.

:D Hope it Helps (I dunno why I put it on this answer box now)

Answer:

Yes.

Step-by-step explanation:

Note that the point:

(x , y) = (-1 , 4)

x = -1

y = 4

Plug in the corresponding numbers for the corresponding variables in the given equation:

y = 3x + 7

(4) = 3(-1) + 7

Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis, Exponent (& Roots), Multiplication, Division, Addition, Subtraction.

First, multiply 3 with -1:

4 = (3 * -1) + 7

4 = -3 + 7

Next, simplify by adding -3 with 7:

4 = (-3 + 7)

4 = 4

Yes. (-1 , 4) is a solution for y = 3x + 7, as the two sides of the equation equal.

Mary invests £12,000 in a savings account the account pays 1.5% compound interest per year work out the value of her investment after 2 years.​

Answers

Answer:

The value of Mary's investment after two years = £12362.7

Step-by-step explanation:

P = Principal / initial amount

R = rate of interest per cent per year

T = number of years

A = final amount at the end of T years

Then:

A = P*(1 + R/100)^2

In our example:

P = £12000

R = 1.5 per cent per year

T = 2 years

Thus:

A = 12000*(1 + 1.5/100)^2

  = 12000*(1 + 0.015)^2

  = 12000*(1.015)^2

   = 12000*(1.030225)

   = 12362.7

Value of investment after two years = £12362.7

At Rosa's Rose Shop, a bouquet containing a dozen roses costs $20. If the price of a bouquet is directly proportional to the number of roses it contains, how many dollars will a bouquet of 39 roses cost?

Answers

Answer:

It will cost $65.

Step-by-step explanation:

A dozen is 12. To find how much it will cost, we can divide the bouquet by 12.

39 ÷ 12 = 3 r3

with the remainder, we can

12 ÷ 3 = 4

3 is 1/4 of 12.

So we can multiply the price of bouquet by 1/2 to find the remainder's price. The whole equation would look like this:

(3x20) + (1/4 x 12)

60 + (1/4 x 20)

60 + 5

65

The answer is 65.
