There are 33 of them altogether and pay £311 in total. How many kids are in the family? Adults pay £15 and kids pay £7
Answer:
Step-by-step explanation
Let x be the number of adults and y the number of kidsWe can then write this two equations :
x+y= 33
15x+7y= 311
let's solve the two eaquationsto do that we should combine them both in a way that help us get rid of one of the variables.
Let's multiply the first equation by -7 to get rid of y by adding it to thr second equation
-7x-7y= -231
now add both equations .
15x+7y-7x-7y=311-231
we get : 8x = 80
as you notice y is gone and we get a classic easy equation to solve
x= 80/8
= 10
so the number of adults is 10
let's go back to the first equation ( x+y= 33) and replace x with 10
10+y= 33
y= 33-10
=23
let's check using the second equation :
(10*15)+(23*7) = 311
that is true
so :
the number of adults is 10 the number of kids is 23Find the solution of the following simultaneous inequalities: x - 7 –1
Answer:

An Indiana corn grower has 1000 bushels of corn that are to be divided between markets in Indianapolis and fort Wayne. These two markets need at least 100 bushels and 300 bushels. Determine the system of inequalities that describes the above situation.
The number 686 can be expressed as a product of prime factors in the form p x qr. The value of p+q+r is _________. Work must be shown.
Answer:
p + q + r is 12.
Step-by-step explanation:
Prime factors of a number is the expression of the number in terms of the product of its factors that are prime numbers only.
The prime factor of 686 = 2 x 7 x 7 x 7. Which can be expressed in the form;
p × [tex]q^{r}[/tex] as 2 × [tex]7^{3}[/tex].
So that, p = 2, q = 7 and r = 3.
p + q + r = 2 + 7 + 3
= 12
Therefore, the sum of p, q, and r is 12.
Which is a better deal? Three movie tickets for 18 dollars or 8 movie tickets for 42 dollars? How do you know? How much money do you save per ticket with the better deal?
Answer:
$42 for 8 tickets
Step-by-step explanation:
To tell which is the better deal you need to find out how much each ticket costs per scenario
$18 for 3 tickets you will need to do 18/3 which will give you $6 a ticket
$42 for 8 tickets you will need to do 42/8 which will give you $5.25 a ticket
$42 option is cheaper per ticket so it is therefore the better option.

Which step is the same in the construction of parallel lines and the construction of a perpendicular line to a point off a line?
Answer:
Both types of lines are built on the same plane although they meet different objectives for which they are built.
Step-by-step explanation:
The difference is that in the case of parallel lines they will never cross and in the case of perpendicular lines if they cross each other, which can give rise to the formation of right angles to each other.

Answer:
A = (4π/3 -√3) m^2
Step-by-step explanation:
The area of a sector with a given radius and arc measure is given by ...
A = (1/2)r^2(θ -sin(θ))
Filling in the given values, the area is ...
A = (1/2)(2 m)^2(2π/3 -sin(2π/3)) = 2(2π/3 -√3/2) m^2

(1) Factor the GCF out of the trinomial on the left side of the equation. (2 points: 1 for the GCF, 1 for the trinomial) 2x²+6x-20=0 (2) Factor the polynomial completely. (4 points: 2 point for each factor) (3) If a product is equal to zero, we know at least one of the factors must be zero. And the constant factor cannot be zero. So set each binomial factor equal to 0 and solve for x, the width of your project. (2 points: 1 point for each factor) (4) What are the dimensions of your project? Remember that the width of your project is represented by x. (2 points: 1 point for each dimension) thank you so much, sorry if it's a little confusing!!
Step-by-step explanation:
(1) Factor the GCF out of the trinomial on the left side of the equation. (2 points: 1 for the GCF, 1 for the trinomial) 2x²+6x-20=0
2x²+6x-20
2(x²+3x-10)
the factors are 2 and (x²+3x-10)
(2) Factor the polynomial completely. (4 points: 2 point for each factor)
2(x²+3x-10)
2(x²-2x+5x-10)
2(x(x-2) + 5(x-2)) group like terms
2(x+5)(x-2)
(3) If a product is equal to zero, we know at least one of the factors must be zero. And the constant factor cannot be zero. So set each binomial factor equal to 0 and solve for x, the width of your project. (2 points: 1 point for each factor)
constant = 2 cannot be zero
the other factors are (x+5) and (x-2)
(x+5)=0 => x= -5
or
(x-2)=0 => x=2
(4) What are the dimensions of your project? Remember that the width of your project is represented by x. (2 points: 1 point for each dimension)

Answer:
It has a 10° angle.Option B is the correct option
Step-by-step explanation:
Dilation factor doesn't change the angle. So, angle remains same.

Conjecture about the properties that change and the properties that stay the same when creating quadrilaterals that are not parallelograms. Check all that apply. The sum of the interior angles will still be 360°. Both pairs of opposite sides will not be parallel. Both pairs of opposite sides will not be congruent. The diagonals will not bisect each other.
A quadrilateral is a four sided shape with two diagonals that bisects each other. The sum total of the interior angles is always 360° for any quadrilateral no matter the shape of the quadrilateral.
It must be noted that both pairs of opposite sides of some quadrilaterals are equal e.g Parallelogram while some are not e.g Trapezium, rhombus, trapezoid etc.
When creating quadrilaterals that are not parallelograms, the following property of such quadrilateral will therefore remains the same.
• The sum of the interior angles will still be 360°.
The following properties will change when creating quadrilaterals that are not parallelograms.
• Both pairs of opposite sides will not be parallel. e.g Trapezoids and rhombus
• Both pairs of opposite sides will not be congruent (will not be the same)

Options A and C are correct.
- The sum of the interior angles will still be 360°.
- Both pairs of opposite sides will not be congruent.

Conjecture about the properties that change and the properties that stay the same when creating quadrilaterals that are not parallelograms. The new quadilateral has angles
Angle LMN = 85°
Angle MNO = 99°
Angle NOL = 81°
Angle OLM = 95°
Check all that apply.
- The sum of the interior angles will still be 360°.
- Both pairs of opposite sides will not be parallel.
- Both pairs of opposite sides will not be congruent.
- The diagonals will not bisect each other.
Solution
A sketch of the new quadilateral is provided in the attached image.
Checking the statements one at a time.
- The sum of the interior angles will still be 360°.
The sum of interior angles for all four sided plane figures is 360°, hence, the new quadilateral too, although, not a parallelogram anymore, will still have interior angles that sum up to 360°. So, this is a statement that doesn't change with change in figure from parallelogram to other quadilaterals.
- Both pairs of opposite sides will not be parallel.
We cannot tell if this is true just from the information on the angles provided.
- Both pairs of opposite sides will not be congruent.
This is evident as one of the condition for opposite sides to be congruent is for opposite angles too to be equal. None of the opposite angles are equal, hence, this statement is true too.
- The diagonals will not bisect each other.
This also isn't evident from the limited information provided. So, we cannot select it as a correct statement.

4. Find the height of a cylinder whose radius is 7cm and the total surface area is 968 sq.cm
(1 Point)
17cm
16cm
15cm
14cm
(its an emergency the due date is about to finish so let's make it quick)
Answer:
Height of the cylinder = 15
Step-by-step explanation:
According to the question, TSA=968
TSA of cylinder=2π r (r+h2*22 / 7*7 (7+h) = 968
2*22 (7+h) = 968
(7+h) = 968/44
7+h=22
h = 22-7
= 15 cm

the solution.
y = 2x + 3
y = - 3x + 3
Answer:
(0, 3).
Step-by-step explanation:
y = 2x + 3
y = -3x + 3
2x + 3 = -3x + 3
5x = 0
x = 0
y = 2 * 0 + 3
y = 0 + 3
y = 3
y = -3 * 0 + 3
y = 0 + 3
y = 3
So, the solution to the system of equations is (0, 3).
Hope this helps!

SOMEBODY HELPPP PLEASEEEE. I don’t understand
Answer:
a) 18
b) 10
c) x^2 - 4x + 5
d) 4x^2 + 2
Step-by-step explanation:
f(x) = 4x - 2
g(x) = x^2 + 1
a) f(5) = 4(5) - 2 = 20 - 2 = 18.
b) g(-3) = (-3)^2 + 1 = 9 + 1 = 10.
c) g(x - 2)...
g(x - 2) = (x - 2)^2 + 1 = x^2 - 2x - 2x + 4 + 1 = x^2 - 4x + 5.
d) f(g(x)) = f(x^2 + 1) = 4(x^2 + 1) - 2 = 4x^2 + 4 - 2 = 4x^2 + 2.
Hope this helps!
