Step-by-step explanation:
make x the subject of the following: k = 2(3x - 5)
Answer:
x = (k+10)/6
Step-by-step explanation:
k = 2(3x - 5)
Distribute the 2
k = 6x - 10
Add 10 to each side
k+10 = 6x-10+10
k+10 = 6x
Divide each side by 6
(k+10)/6 = 6x/6
(k+10)/6 = x
Answer:
x = (k + 10) / 6
Step-by-step explanation:
k = 2(3x - 5)
k = 6x - 10
k + 10 = 6x
(k + 10) / 6 = x
Find the values of x and y.
Answer:
Given, x,y and 40 are the angles of a triangle.
Therefore, x+y+40=180
x+y=140
The difference between the two angles x and y is 30.
Therefore, x−y=30 ....(2)
Add equations (1) and (2), we get
2x=170
⇒x=85
Substitute this value n equation (2), we get
85−y=30
⇒y=85-30
⇒y=55
Therefore, angles of a triangle are x=85, y=55 and 40.
Answer:
Step-by-step explanation:
for x :
180° - 40° = 140°
40° / 2 = 20°
x = 20°
for y :
20° + 90° = 110°
180° - 110° = 70°
x = 70°

Step-by-step explanation:
Answer:
36p^2 - 25Step-by-step explanation:
●Using the identity :-
●(a+b) (a-b) = a^2 - b^2
●Here, a = 6p and b = 5
=> (6p+5) (6p-5)
=> (6p)^2 - (5)^2
=> 36p^2 - 25

In a class 18 children are girls A quarter of the children in the class are boys. Altogether, how many children are in the class?
Answer:
24
Step-by-step explanation:
let x be the number of children in the class , then
number of boys = [tex]\frac{1}{4}[/tex] x , so
x = [tex]\frac{1}{4}[/tex] x + 18 ( multiply through by 4 to clear the fraction )
4x = x + 72 ( subtract x from both sides )
3x = 72 ( divide both sides by 3 )
x = 24
There are 24 children in the class

What is the measure of y? 4 16 z y x
Answer:
y = 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
y² = product of the segments on the hypotenuse of the large right triangle.
y² = 4 × 16 = 48 ( take square root of both sides )
y = [tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]
Examine the diagram.
A triangle has angles 1, 2, 3. Angle 4 is an exterior angle to angle 3.
For the angles shown in the diagram, which statements are true? Select all that apply.
The sum of m∠3 and m∠4 is 180°.
The sum of the measures of the adjacent interior angle and one of the remote interior angles is equal to the measure of the exterior angle.
∠3 is supplementary to ∠1.
m∠4 = m∠1 + m∠2.
m∠1 + m∠2 + m∠3 = 180°
The statements that are true regarding the diagram given are:
m∠3 + m∠4 = 180° (angles on a straight line)m∠4 = m∠1 + m∠2 (external angle theorem)m∠1 + m∠2 + m∠3 = 180° (triangle sum theorem).What is the Triangle Sum Theorem?The triangle sum theorem states that all the three interior angles in a triangle have a sum of 180 degrees all together.
Thus, in the diagram given, the statements that are all true are:
m∠3 + m∠4 = 180° (angles on a straight line)
m∠4 = m∠1 + m∠2 (external angle theorem)
m∠1 + m∠2 + m∠3 = 180° (triangle sum theorem).

check the injectivity and subjectivity of the function:
[tex] \sf \large f:N \longmapsto \: N \: given \: by \: f(x) = x {}^{3} .[/tex]
Answer:
The function is injective but nor surjectiveStep-by-step explanation:
We see that:
f(x) = x³For any x₁ and x₂ ∈ N,
f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbersIt it confirmed one-to-one, hence it is injective
Check the surjectivity:
f(x) = y ∈ N
x³ = yy = ∛xLet y = 2, then:
2 = x³x = ∛2 ∉ NSince x is not natural, the function is not surjective
Answer:
This function is injective only.
Step-by-step explanation:
N = natural numbers = positive whole numbers equal to or greater than 1.
Therefore [tex]N \rightarrow N[/tex] means that both the input and output are natural numbers.
A function is surjective if for every element in the codomain, there is at least one element in the domain.
Therefore, this function is NOT surjective. For example, there is no natural number for x for which f(x) = 2.
A function is injective if for every element in the codomain, there is at most one element in the domain. This is also called "One-to-One".
Therefore, this function IS injective as there is either none or only one value of x for each value in the codomain.

Lucas is having yogurt and an apple for a snack. There are five containers of yogurt in the refrigerator: three are raspberry, one is vanilla, and one is peach. There are also two green apples and three red apples.
If he reaches into the refrigerator to get a yogurt without looking, what is the probability that Lucas will choose a raspberry yogurt?
What is the probability that he will choose a red apple if it is the first item he selects?
What is the probability that Lucas will eat a raspberry yogurt and a red apple?
Answer:
If Lucas reaches into the refrigerator to get a yogurt without looking, there is a 3/5 probability that Lucas will choose a raspberry yogurt.
There is a 3/5 probability that he will choose a red apple if it is the first item he selects.
There is a 9/25 probability that Lucas will eat a raspberry yogurt and a red apple.
Step-by-step explanation:
3/5 x 3/5 = 9/25
Answer:
Probability of yogurt being raspberry = 3/5 = 0.6Probability of choosing a red apple = 3/10 = 0.3Probability of raspberry yogurt AND red apple = 9/50 = 0.18Step-by-step explanation:
Total of 5 yogurts: 3 raspberry + 1 vanilla + 1 peach
Probability of yogurt being raspberry = 3/5 = 0.6
Total of 5 apples: 2 green + 3 red
Total number of snacks = 10
Probability of choosing a red apple = 3/10 = 0.3
Probability of raspberry yogurt AND red apple = 0.6 x 0.3 = 9/50 = 0.18

How much material, in square inches, is needed to make the flag? square inches If the material costs $0. 15 per square inch, how much will Marta spend on materials to make the flag? $.
The amount of material needed by Marta to make the flag is;
[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] square inch.
The total cost of making the flag is;
[tex]\rm 0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] dollar.
Given
Marta is making a flag with the given dimensions.
The perimeter of the flag is 100 inches.
Let us consider that the flag has a triangular shape.
Hero's formula;According to the Hero's formula;
The area of the triangle is given by;
[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where, s is the semi perimeter and a, b, and c are the sides of the triangle.
Semi perimeter s = P/2,
Since the perimeter of the flag is 100 inches.
[tex]\rm S=\dfrac{100}{2}\\\\S=50[/tex]
The dimensions of triangular shape are [tex]\rm d_1, d_2 \ and \ d_3[/tex].
Then,
The area of the triangular flag becomes;
[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]
So the amount of material needed to make the flag is;
[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]
Therefore,
The cost of material = C = $0.15 per square inch
So the total cost in making the flag will be;
[tex]\rm C\times A=0.15 \times A\\\\=0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].
Hence, The amount of material needed by Marta to make the flag is [tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

Answer: her present age is 4
Step-by-step explanation:
Proof: 4+12=16
Square root 4 is 16
Answer:
4
Step-by-step explanation:
Let x represent her present age. The given relation is ...
x +12 = x^2
Putting this in standard form, we can factor it:
x^2 -x -12 = 0
(x -4)(x +3) = 0
Solutions to this quadratic are x = 4, x = -3. The -3 solution is extraneous in this context.
The girl's present age is 4.
