Answer:

3 and 20

Step-by-step explanation:

We have 2 numbers, we will call them a and b.

We have: <u>a = </u>\frac{3}{20}<u>b </u>and <u>a + b = 23</u>

=> \frac{3}{20}b + b = 23

=> \frac{23b}{20} = 23

=> 23b = 460

=> <em>b = 20</em>

=> <em>a = 3</em>

Answer:

Here's what i know:

x + y = 23

3y / 20 =x

 

Here we can use substitution to help find our answer:

y + 3y/20 = 23

20y/20 + 3y/20 = 23

23y/20 = 23

23y = 23 * 20

y = 23 * 20 / 23

y = 20

 

x + 20 = 23

x = 3

The quotient of forty-nine and a number is greater than or equal to seven.
Nadusha1986 [10]
" the quotient " means divide

49/x > = 7 <== ur inequality
multiply both sides by x
49 > = 7x...now divide both sides by 7
49/7 > = x
7 > = x ....or x < = 7 <== ur answer

A person standing at the top of Mountain Rainier would be approximately 2.7 mi high. The radius of earth is 3959 mi. What is the
astraxan [27]

Answer: 146.2\text{ miles}

Step-by-step explanation:

Given: The approximate height of Mountain Rainier h= 2.7 miles

The radius of earth = 3959 miles.

Let d be the distance to the horizon from this point.

We know that the line of sight to the horizon , the radius at the horizon and the radius at the mountain from a right angle triangle.

Therefore, by Pythagoras's theorem we have

d=\sqrt{(R+h)^2 - R^2}\\\\\Rightarrow\ d=\sqrt{(3959+2.7)^2-(3956)^2}\\\\\Rightarrow\ d=\sqrt{(3961.7)^2-(3956)^2}\\\\\Rightarrow\ d=\sqrt{15695066.89-15673681}\\\\\Rightarrow\ d=\sqrt{21385.89}\\\\\Rightarrow\ d=146.23915344\approx146.2\text{ miles}

Hence,  the distance to the horizon from this point= 146.2\text{ miles}

4c + 8 = 20 can solve this
Anna35 [415]

You are solving for the variable (c).

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)

First, subtract 8 from both sides

4c + 8 (-8) = 20 (-8)

4c = 20 - 8

4c = 12

Next, to fully isolate the variable (c), divide 4 from both sides

(4c)/4 = (12)/4

c = 12/4

c = 3

3 is your answer for c.

You wanted to join a booth fair, and you are aiming to get a profit that is twice as
sashaice [31]

You wanted to join a booth fair, and you are aiming to get a profit that is twice as  your capital. Using the given information, your sample plan may be as follows:

Product                   Organic skincare products for women

Description             An organic skincare cream and soap that brightens

                                 and moisturizes your skin.

Goal                          To provide anti-aging skin for women and

                                  maintaining  their skin body.

Capital                      15000

Fixed Cost                  7000

Variable Cost             8000

Profit function            300(a) = 450a - 150a

To prove that the profit function will yield twice the capital.

This profit function: 300(y) = 450y - 150y will help achieve twice profit as your capital.

Profit function = revenue function r(y) - cost function c(y)

300(y) = 450y - 150y

where;

  • y = no of units produced and sold.
  • p = profit sold per unit

Cost function C(y) = fixed cost + (variable cost) × (amount of unit sold)

Assumption:

Cost function C(y) = 7000 + (80 × 100)

Cost function C(y) = 7000 + 8000

Cost function C(y) = 15000

Revenue function R(y) = price per revenue sold × no of sold units

R(y) = 450 × 100

R(y) = 45000

∴

Profit function = 45000 - 15000

Profit function = 30000

Therefore, can conclude that the profit function is revenue function r(y) - cost function c(y).

Hence the formula:

Profit function = revenue function r(y) - cost function c(y)   (Proved)
