Fred's age is 36 years old and Nathan's age is 9 years old

Step-by-step explanation:

Let

f -----> Fred's age

n ----> Nathan's age

we know that

-----> equation A

----> equation B

equate the equations and solve for n

Find the value of f

therefore

Fred's age is 36 years old and Nathan's age is 9 years old

Answer: 20 days

Step-by-step explanation:

Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:

= 15% × 40

= 0.15 × 40

= 6

6 sales out of every 40 calls per day.

The number of calls to make 120 sales will be:

= 15% of x = 120

0.15 × x = 120

0.15x = 120

x = 120/0.15

x = 800 calls

Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:

= 800/40

= 20 days

Answer:800

Step-by-step explanation:

I'm assuming (P) represents profit

Apply out 700 in the equation

700=1.50n-500

Add 500 to each side

1200=1.50n

Divide each side by 1.50

800=n.

800 bars must be sold

800 candy bars must be sold to make a profit of $700.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, p = 1.50n - 500, assuming no. of candy bars to be n and we had a profit of $700.

∴ No. of candy bars sold to make a profit of $700 is,

700 = 1.50n - 500.

700 + 500 = 1.50n.

1.50n = 1200.

n = 1200/1.50.

n = 800 candy bars.

Answer:

There will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days

Step-by-step explanation:

The given parameters are;

The half life of the radioactive substance = 45 days

The mass of the substance initially present = 6.2 grams

The expression for evaluating the half life is given as follows;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]

Where;

N(t) = The amount of the substance left after a given time period = 1 gram

N₀ = The initial amount of the radioactive substance = 6.2 grams

[tex]t_{1/2}[/tex] = The half life of the radioactive substance = 45 days

Substituting the values gives;

[tex]1 = 6.2 \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]

[tex]\dfrac{1}{6.2} = \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]

[tex]ln\left (\dfrac{1}{6.2} \right ) = {\dfrac{t}{45} \times ln \left (\dfrac{1}{2} \right )[/tex]

[tex]t = 45 \times \dfrac{ln\left (\dfrac{1}{6.2} \right ) }{ln \left (\dfrac{1}{2} \right )} \approx 118.45 \ days[/tex]

The time that it takes for the mass of the radioactive substance to remain 1 g ≈ 118.45 days

Therefore, there will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days.

Equation: y = 5/4x

Answer:

x=10

Step-by-step explanation:

I think..i tired

Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

2

Simplify  \frac{500}{5}5500  to  100100.

{x}^{2}=-100x2=−100

3

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

4

Simplify  \sqrt{-100}√−100  to  \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

5

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.
