p.s i have class
Answer:
2.4 Litres of waterStep-by-step explanation:
80% of (3 litres)
You can take 3 litres to be 3000 ml which is how I solved it.
OPTION 1_________80/100 x 3000
=2400 or 2.4 litres
The same can go with not taking ml which you can just use litres
OPTION 2_________80/100 x 3
=2.4 litres
I used the ml since I do not need the calculator for that one and it is faster to calculate.

Answer:
x = 10
General Formulas and Concepts:

Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
(7x - 1) + (13x - 19) = 180
Step 2: Solve for x
Combine like terms: 20x - 20 = 180Isolate x term: 20x = 200Isolate x: x = 10Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: (7(10) - 1) + (13(10) - 19) = 180Multiply: (70 - 1) + (130 - 19) = 180Subtract: 69 + 111 = 180Add: 180 = 180Here we see that 180 does indeed equal 180.
∴ x = 10 is the solution to the equation.

Which of the following is NOT always true of a function and its inverse?
The statement that is not always true of inverse functions is (d) f-1(x) is a function
What are inverse functions?Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function
How to determine the statement that is not always true of inverse functions?As mentioned above,
The inverse functions are the opposite of an original equation
This means that:
If a function is f(x), then the inverse if f-1(x)
However, all inverse equation are relations, but not all inverse equations are functions
This means that the statement that is not always true of inverse functions is (d) f-1(x) is a function

Max puts a stopper in the bathtub and turns on the faucet at t=0. After 5 minutes, there are 11 gallons of water in the tub and after 10 minutes, there are 22 gallons in the tub. Write an equation that relates the number of gallons, g, to the time, t. Does the relationship represent a linear function? Justify your response.
Answer:
y = 2.2x
Yes, it represents a linear function
Step-by-step explanation:
Given that :
Stopper applied at t = 0
At t = 5 minutes ; water in tub = 11 gallons
At t = 10 minutes ; water in tub = 22 gallons
General form of a linear function :
y = mx + c
Where c = intercept ; m = Slope ; y and x are dependent and independent variables respectively
The intercept = gallon of water at t = 0 ; this is not given and will be taken as 0
Slope = change in y / charge in x
Slope = (22 - 11) / (10 - 5)
Slope = 11 / 5
Slope = 2.2
Hence ;
y = 2.2x + 0
y = 2.2x
Yes, it represents a linear function

As C is the mid-point of BD.
Therefore, BC=DC ...(i)
As AB ⊥ BD and ED ⊥ BD
So, ∠ABC= 90° and ∠EDC= 90°
Therefore, ∠ABC=∠EDC= 90° ...(ii)
As two line segments, AE and BD intersect at point C, so the vertically opposite angles are equal.
Therefore, ∠BCA=∠DCE ...(iii)
Now, in ΔABC and ΔEDC,
Angle, ∠BCA=∠DCE [ from equation (iii)]
Side, BC=DC [ from equation (i)]
Angle, ∠ABC=∠EDC [ from equation (ii)]
So, by ASA property of congruency, ΔABC and ΔEDC are congruent
Hence, ΔABC ≅ ΔEDC.

Let x = the first number
Let x + 1 = the second number
x + x + 1 = 55 Combine the x's
2x + 1 = 55 Subtract 1 from both sides.
2x = 54 Divide both sides by 2
x = 27 the second number would be 28
Tommy went to Taco World and bought 3 tacos and 4 burritos and spent $14.30. Burritos cost twice as
much as tacos. What was the cost of each taco and each burrito?
If Tommy spent $14.30 and the cost of burritos is twice as much as tacos then the cost of Taco is $1.30 and the cost of burrito is $2.60.
Given that Tommy spent $14.30 and the cost of burritos is twice as much as tacos .
We are required to find the cost of each tacos and burrito.
Suppose the cost of a taco be x and the cost of burrito be y.
Because the cost of burrito is twice as the cost of taco so y=2x.
Total expenditure by Tommy=3x+4*2x
14.30=3x+8x
11x=14.30
x=1.30
y=2*1.3
y=$2.60
Hence if Tommy spent $14.30 and the cost of burritos is twice as much as tacos then the cost of Taco is $1.30 and the cost of burrito is $2.60.

Answer:
2) tri ABC is congreunt to tri DEF
Step-by-step explanation:
you would have to make sure you name the traingles in a specific order so the congruent angles in both triangles are listed in the same order :))
The option that best describes the relationship between AABC and ADEF is AABC ~ ADEF, the correct option is B.
What are similar triangles?
All similar triangles are triangles that share these two features presented as follows;
1. Congruent angle measures.
2. Proportional side lengths.
We are given that;
AB is similar to DE: BC is similar to EF; AC is similar to DF; ZA is similar to ZD; ZB is similar to ZE; ZC is similar to ZF.
Now,
The relationship between two similar triangles is that their corresponding angles are equal and their corresponding sides are proportional1. This means that if AABC and ADEF are similar, then:
∠A = ∠D
∠B = ∠E
∠C = ∠F
AB/DE = BC/EF = AC/DF
To describe this relationship, we can use a notation that shows which angles and sides correspond to each other. For example, we can write:
AABC ~ ADEF
This means that triangle ABC is similar to triangle DEF and the order of the letters shows how they match up. The first letter of each triangle corresponds to the first angle, the second letter corresponds to the second angle, and so on.
Therefore, by similar triangle properties the answer will be AABC ~ ADEF.
