Answer:

1/3

Step-by-step explanation:

total is 1.

Left = 1 - 2/3

       = 1/3

The y-intercept represents the initial temperature of the liquid before cooling  and the slope represent the changes in temperature for every m minutes.

y = 100 - 5m

where

y = temperature in degree Celsius

m = cooling for number of minutes

Using the slope intercept equation,

where

m = slope

b = y-intercept

Therefore,

y - intercept = 100

slope(m) = 5

Therefore, the y-intercept represents the initial temperature of the liquid before cooling  and the slope represent the changes in temperature for every m minutes.

The baker needs to use 100/3 pounds of 90% chocolate to make the cake.

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the amount of 90% chocolate. Using equation:

100 * 70% + x * 90% = (x + 100) * 75%

100 * 0.7 + 0.9 * x = (x + 100) * 0.75

70 + 0.9x = 0.75x + 75

x = 100/3

Option (C) a sequence of statements that demonstrates the truth of an assertion is the best definition of mathematical proof.

A mathematical proof is an inferential justification for a mathematical claim that demonstrates how the premises logically support the conclusion.

As we know, mathematical proofs are a set of sequential statements that assist in demonstrating the truth of a proposition.

For example:

2n + 1 = 3n

If n = 1 the above expression is true.

To proof the above expression plug n = 1:

2(1) + 1 = 3(1)

2 + 1 = 3

3 = 3  (true)

Thus, option (C) a sequence of statements that demonstrates the truth of an assertion is the best definition of mathematical proof.

Step-by-step explanation:

6c=72

We can divide by 6 on both sides and get

c=72/6

Answer:

both lori and jayden are correct

Step-by-step explanation:

first solve 72/6, you should get 12. Therefore c should be 12 since to get the number of cards in a pack you divide the total number of cards by the number of packs.
plug in 12 for the equation 6c=72

6x12 = 72 (6 being the number of packs and twelve the number of cards per pack).

Answer:

8. ∠1=118° ∠2=118°

9. ∠1=72° ∠2=108°

10. ∠1=127° ∠2=127°

Step-by-step explanation:

8. In this problem, 118° is corresponding to ∠1, meaning they are congruent. ∠2 is supplementary with ∠1, meaning that together, they equal 180°. So, to get ∠2, you must subtract 118° from 180°

9. In this problem, 72° is same side interior with ∠1, meaning they are congruent. ∠2 is supplementary with ∠1, so you do 180°-72°=  108°

10. In this problem, ∠1 is vertical angles with 127°, making them equal to each other. ∠2 is corresponding with 127°, making them also equal.

The total area of the walls is 140 m²

Since the room is in the shape of a cuboid, and we require the area of the walls of the room, the walls of the cuboid are the walls of the room.

So, the total surface area of a cuboid is A = 2(lb + lh + bh) where

Since we require the total area of the walls, lb which is the area of the floor is removed from the equation.

So, the area of the walls is A' = 2(lh + bh)

= 2h(l + b)

Since the dimensions of the floor are 4 meters by 6 meters and the height of the basement is 7 m. So,

So, substituting the values of the variables into the equation, we have

A' = 2h(l + b)

A' = 2 × 7 m × (4 m + 6 m)

A' = 14 m × 10 m

A' = 140 m²

So, the total area of the walls is 140 m²

- 2 x - 6 = 12  x = -9

Step-by-step explanation:

Answer:

-5 or 5

Step-by-step explanation:

Because when it is absolute value, all real numbers result in positive numbers.

We should confirm that f(x) has an inverse in the first place. If it does, then

[tex]f\left(f^{-1}(x)\right) = x[/tex]

Given that f(x) = x/(2 - x), we have

[tex]f\left(f^{-1}(x)\right) = \dfrac{f^{-1}(x)}{2 - f^{-1}(x)} = x[/tex]

Solve for the inverse:

[tex]\dfrac{f^{-1}(x)}{2 - f^{-1}(x)} = x[/tex]

[tex]f^{-1}(x) = 2x - x f^{-1}(x)[/tex]

[tex]f^{-1}(x) + x f^{-1}(x) = 2x[/tex]

[tex]f^{-1}(x) (1 + x) = 2x[/tex]

[tex]f^{-1}(x) = \dfrac{2x}{1+x}[/tex]

Then

[tex]f^{-1}(-2) = \dfrac{2(-2)}{1-2} = \boxed{4}[/tex]

Note that this is the same as solve for x when f(x) = -2 :

x/(2 - x) = -2   ⇒   x = 4

Answer:

x = 2, y = 2

Step-by-step explanation:

Equating the x and y coordinates , that is

2x + 3 = 7 ( subtract 3 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

and

7 = 3y + 1 ( subtract 1 from both sides )

6 = 3y ( divide both sides by 3 )

2 = y
