Step-by-step explanation:

80% of (3 litres)

You can take 3 litres to be 3000 ml which is how I solved it.

80/100 x 3000

=2400 or 2.4 litres

The same can go with not taking ml which you can just use litres

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.

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.

Answer:

27 and 28

Step-by-step explanation:

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

The statement that is not always true of inverse functions  is (d) f-1(x) is a function

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

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

(2x - 2) - 2x > (4x + 6) - 2x

-2 > 2x + 6

(-2) - 6 > (2x + 6) - 6

-8 > 2x

-4 > x

Answer:

x < - 4

Step-by-step explanation:

2x - 2 > 4x + 6 ( subtract 4x from both sides )

- 2x - 2 > 6 ( add 2 to both sides )

- 2x > 8

divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

Answer:

The correct answer is A. one solution.

The actual solution is x = 2.5.

Step-by-step explanation:

Here is the solution below:

Step 1: 2 + 2x + 1 = 3 + 2 + 3 <----- Here is the original problem.

Step 2: 2 - 2 + 2x + 1 - 1 = 8 - 2 - 1 <----- Subtract 1 and 2 from both sides.

Step 3: 2x = 5 <----- Simplify

Step 4: 2x/2 = 5/2  <---- Divide both sides by 2.

x = 2.5

Answer:

The linear function is;

Tn-1 = Tn + 3

What this mean is that to get the term before the present term, we add 3 to the present term

Step-by-step explanation:

Here, we want to write a liner function to describe the function

As we can see from the numbers listed,

the next term is simply obtained by deducting 3 from the previous term

We can write this as:

Tn-1 = Tn + 3

Where Tn is the next term and Tn-1 is the previous term

What the function is saying is that to get the term before the present term, we add 3 to the present term

As the system of equations has only one solution, thus the solution consistent.

Step-by-step explanation:

Given the system of equations

4x - 5y = 19

y = x - 4

Solving the system of equations by using the substitution method.

[tex]\begin{bmatrix}4x-5y=19\\ y=x-4\end{bmatrix}[/tex]

[tex]\mathrm{Subsititute\:}y=x-4[/tex]

[tex]\begin{bmatrix}4x-5\left(x-4\right)=19\end{bmatrix}[/tex]

[tex]4x-5\left(x-4\right)=19[/tex]

[tex]-x+20=19[/tex]

isolate x for [tex]-x+20=19[/tex]

[tex]-x+20=19[/tex]

[tex]-x=-1[/tex]

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.

The quadratic function that includes the set of values is y = -2x^2 + 7x + 6

The set of values is given as

(0,6) (2,12) (3,9)

A parabola is represented as

y = ax^2 + bx + c

At (0, 6), we have

6 = a(0)^2 + b(0) + c

This gives

c = 6

So, we have

y = ax^2 + bx + 6

At (2, 12), we have

12 = a(2)^2 + b(2) + 6

This gives

4a + 2b = 6

At (3, 9), we have

9 = a(3)^2 + b(3) + 6

This gives

9a + 3b = 3

Using a graphing tools, we have

a = -2 and b = 7

So, we have

y = -2x^2 + 7x + 6

Hence, the quadratic function that includes the set of values is y = -2x^2 + 7x + 6

The angular speed of the bicycle's wheels that are traveling at 25 mi/h is 1885.7 rad/min

To solve this angular speed problem the formula and the procedure we will use is:

v = w * r

Where:

Information about the problem:

Calculating the radius of the wheel, we have:

r = d/2

r = 28 inch/2

r = 14 inch

Converting the velocity unit from mi/h to inch/min, we get:

25 mi/h * (63360 inch / 1 mi) * (1h / 60 min) = 26400 inch/min

Applying the tangential velocity formula and isolating the angular velocity, we get:

v = w * r

w = v / r

w = 26400 inch/min / 14 inch

w = 1885.7 rad/min

When an object is in uniform circular motion, the angle described by the radius in each unit of time is known as angular speed. It is measured in units of (rad/s) (revolutions/s).
