Answer:

Theo Should use 1.3 cups of Sugar to make 24 cookies.

Step-by-step explanation:

Given;

Number of cookies required by recipe = 36 cookies

Number of cookies Theo wants to use = 24 cookies

Number of cups sugar recipe requires = 2 cups

We need to find Number of cups sugar Theo should use to make cookie according to recipe.

Now,

For 36 cookies = 2 cups of sugar

So For 24 cookies = Number of cups of sugar required for 24 cookies.

By Using Cross Multiplication we get;

Number of cups of sugar required for 24 cookies = [tex]\frac{24\times2}{36}= 1.33\ cups[/tex]

Hence Theo Should use 1.3 cups of Sugar to make 24 cookies.

Step-by-step explanation:

Answer:

See the explanation

Step-by-step explanation:

Given function

[tex]Y=3x+1[/tex]

We need to find [tex]y[/tex] value corresponding to each [tex]x[/tex] value.

So, plug each [tex]x[/tex] value in equation we get,

[tex]plug\ x=4\\y=3(4)+1\\y=12+1\\y=13\\\\plug\ x=6\\y=3(6)+1\\y=18+1\\y=19\\\\plug\ x=10\\y=3(10)+1\\y=30+1\\y=31[/tex]

Now in next part of question it ask us to check each ordered pair.

Let us plug each [tex]x[/tex] value and [tex]y[/tex] value in the function [tex]y=-3x-5[/tex]

[tex]plug\ (1,-8)\\-8=-3(1)-5\\-8=-3-5\\-8=-8\\\\plug(-5,0)\\0=-3(-5)-5\\0=15-5\\0\neq10\\\\plug\ (-2,1)\\1=-3(-2)-5\\1=6-5\\1=1\\\\plug\ (-1,-2)\\-2=-3(-1)-5\\-2=3-5\\-2=-2\\[/tex]

we can see ordered pair [tex](1,8),(-2,1)and(-1,-2)[/tex] true for function [tex]y=-3x-5[/tex]

STEPS:

First distribute the 5 through the parentheses to get 5q + 135. So the problem now reads 5q + 135 - (-30) = 95.

Now, minus a negative can be changed to plus a positive so - (-30) can be changed to +30 so our equation now reads 5q + 135 + 30 = 95.

Before adding or subtracting anything from both sides of the equation, make sure you simplify the left side as much as possible. Notice that we can add 135 and 30 to get 165 so the left side simplifies to 5q + 165 = 95.

Now we can simply subtract 165 from both sides of the equation to get 5q = -70.

Now simply divide both sides of the equation by 5 to get q = -14.

Answer:

968 ways

Step-by-step explanation:

This is a question of permutation and combination.

Each equation can have two different answers.

Thus the total number of cases will be (for 10 questions) :

[tex]2*2*2*2*.....10times=2^{10}[/tex] cases.

Now to find the number of ways to at least answer 3 questions False will be total minus the number of question with at most 2 False answers.

Total ways (at most 2 answers false) = [tex]1+10_C_1+10_C_2[/tex] ;

∴

The number of ways in which at least 3 have False as the answer is :

[tex]2^{10}-(1+10_C_1+10_C_2)\\=968[/tex] WAYS.

Answer:

The probability of selecting the given event = [tex]\frac{25}{52}[/tex]

Step-by-step explanation:

A card is drawn at random from a standard 52-card deck.

We have to find the probability of selecting an odd numbered card(3,5,7,9) or spade or both.For this we have to find the number of favourable cases.

Favorable cases = 13 (all the spades) + 12(4 odd numbered cards from each of the remaining 3 )

                         = 25

Final probability = [tex]\frac{number of favourable cases}{total number of cases}[/tex]

                             = [tex]\frac{25}{52}[/tex]

Hence the probability = [tex]\frac{25}{52}[/tex]

Answer:

640 cm²

Step-by-step explanation:

The ratio between the area two similar polygon are the ratio between their sides squared.

Given side S₁ and side S₂, you can find the area of the second shape by multiplying the area of the first shape by a factor of (S₂/S₁)².

This might sound confusing if you're not used to hearing math terms so lets solve it in this problem.

The side of the first trapezoid is 5cm, so S₁ = 5

The side of the second trapezoid is 20cm so S₂ = 20.

The ratio between them is 20/5=4

To find the area of the second shape, we just have to multiply the area of the first one by the ratio², ie. (S₂/S₁)².

40(4)² = 40(16) = 640 cm²

Answer:

m = -1/2

Step-by-step explanation:

As we move from the point (-1, 7) to the point (3, 5), x increases by 4 (this is the "run") and y decreases by 2 (this is the "rise").

Thus, the slope of the line connecting these two points is

m = rise / run = -2/4, or m = -1/2.

Answer:

The fraction of trip completed by Andre is  [tex]\frac{31}{24}[/tex] km

Step-by-step explanation:

Given as :

The Total distance between the home to a festival = 1 [tex]\frac{5}{8}[/tex] km

I.e The total distance between the home to a festival =  [tex]\frac{13}{8}[/tex] km

The distance cover by Andre before taking rest =  [tex]\frac{1}{3}[/tex] km

Let The fraction of trip completed by Andre = x km

So, According to question

The fraction of trip completed by Andre = The Total distance between the home to a festival - The distance cover by Andre before taking rest

or, x =  [tex]\frac{13}{8}[/tex] km - [tex]\frac{1}{3}[/tex] km

or, x =  [tex]\frac{39 - 8}{24}[/tex] km

∴ x = [tex]\frac{31}{24}[/tex] km

Or, The fraction of trip completed by Andre = x = [tex]\frac{31}{24}[/tex] km

Hence , The fraction of trip completed by Andre is  [tex]\frac{31}{24}[/tex] km Answer

Answer:

[tex]\frac{4}{15}[/tex]

Step-by-step explanation:

We know that the total distance is

[tex]1\frac{5}{8}km[/tex] which is standard fraction would be [tex]\frac{13}{8}km[/tex].

So, Andre walks [tex]\frac{1}{3}km[/tex], that means he needs to walk the following distance to get to the festival

[tex]\frac{13}{8}-\frac{1}{3}=\frac{39-8}{24}=\frac{31}{24}km[/tex]

Now, to find the fraction of the tripe that represents the distance he already completed, we have to divide

[tex]\frac{1}{3} \div \frac{13}{8}=\frac{1}{3} \times \frac{8}{13}=\frac{8}{30}=\frac{4}{15}[/tex]

Therefore, we completed a [tex]\frac{4}{15}[/tex] part of the total distance.

Answer:

Step-by-step explanation:

Complete the square to do this.  This one is a bit of a pain because of the 7 as our linear term, but a little hard work never killed anyone!

The rules for completing the square are very strict and cannot be strayed from.  The first rule is that the leading coefficient HAS to be a positive 1; ours is a positive 6 so we have to factor it out.  Let's do that first then we can get to rule number 2.

Set the quadratic equal to 0, then move the constant over to the other side.  This is not a rule, per se, but I teach it this way to avoid unnecessary confusion in an already confusing process.  

[tex]6x^2+7x=-2[/tex] and to factor out the 6:

[tex]6(x^2+\frac{7}{6}x)=-2[/tex]

Now for rule #2:  take half the linear term, square it, and add it to both sides.  Our linear term is 7/6.  Half of that is 7/12, and 7/12 squared is 49/144.  BUT we cannot forget about that 6 hanging around out front, refusing to be ignored.  It is a multiplier, so when we add 49/144 inside the parenthesis on the left, we have to add 6(49/144) to the right, giving us:

[tex]6(x^2+\frac{7}{6}x+\frac{49}{144})=-2+\frac{294}{144}[/tex]

We will rewrite now by simplifying.  The left side can be written into a perfect square binomial (which is why we did this in the first place) and the right side can be added.  The left side becomes

[tex]6(x+\frac{7}{12})^2[/tex]

The 7/12 comes from the square root of 49/144, and the x comes from the square root of x-squared.  The right side requires a common denominator:

[tex]-2+\frac{294}{144}=-\frac{288}{144}+\frac{294}{144}=\frac{6}{144}=\frac{1}{24}[/tex]

So now we have

[tex]6(x+\frac{7}{12})^2=\frac{1}{24}[/tex]

Put evertyhing back onto the left side and set it back to equal y and you're done!

[tex]y=6(x+\frac{7}{12})^2-\frac{1}{24}[/tex]

Because the vertex form of a quadratic does not allow us to stray from the format "x -", we have to interpret our h coordinate as "x - (-7/12))" which is movement to the left.  This gives us a vertex of

[tex](-\frac{7}{12},-\frac{1}{24})[/tex]

Answer:

For [tex](2x^2 + 8x - 8)[/tex], the group is CLOSED as it a polynomial.

Step-by-step explanation:

Here, the given polynomials are:

[tex]P(x)=(5x^2+2x-6)\\Q(x)=(3x^2-6x+2)[/tex]

Now, a group G is said to be CLOSED UNDER SUBTRACTION if,

a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G

Now, here:

[tex]R(x)  = P(x) - Q(x) = (5x^2+2x-6) - (3x^2-6x+2) = (2x^2 + 8x - 8)[/tex]

or, [tex]R(x)  = (2x^2 + 8x - 8)[/tex]

Also, R(x) is a POLYNOMIAL.

So, R(x) is an Element of group G.

So, the set G of polynomials.

Hence, for the polynomial  [tex](2x^2 + 8x - 8)[/tex], it will be a polynomial the group is CLOSED.

Answer:

(C) The perimeter of Δ A'B'C'.

(D) The area of Δ A'B'C'.

(E) The measure of ∠B'.

(F) The length of segment A'B'.

Step-by-step explanation:

Given:

A triangle ABC rotated by 180° clockwise around the vertex C(3,4) to create Δ A'B'C.

Now, a rotation is a rigid motion transformation. In rigid transformation, the  size, length, angle measures, perimeter and area of the figure doesn't change and remains the same as the original figure.

Rotation only changes the position of the points on the figure.

Here, as the triangle ABC is rotated about vertex C, the position of vertex A and B will change. But, the angles made by each of the vertices will remain same. Also, the side lengths of the triangle will remain the same. So, the perimeter and area will also not change. As the point of rotation is point C, the vertex C' will be same as vertex C.

So, the correct options are (C), (D), (E), and (F).

Using linear combination method, the solution to given system of equations are (-7, -15)

Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated

Addition is used when the two equations have terms that are exact opposites, and subtraction is used when the two equations have terms that are the same.

Given system of equations are:

2x - y = 1  ---- eqn 1

3x - y = -6 ------ eqn 2

Subtract eqn 2 from eqn 1

2x - y = 1

3x - y = -6

(-) -------------

-x = 7

Substitute x = -7 in eqn 1

2(-7) - y = 1

-14 - y = 1

y = -14 - 1 = -15

Thus the solution to given system of equations are (-7, -15)

Answer:

[tex]P=4x\sqrt{26}\ units[/tex]

Step-by-step explanation:

we know that

The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other

so

Applying the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

c is the length side of the rhombus      

a and b are the semi-diagonals

we have

[tex]a=2x/2=x\ units\\b=10x/2=5x\ units[/tex]

substitute the values

[tex]c^2=x^2+(5x)^2[/tex]

[tex]c^2=26x^2[/tex]

[tex]c=x\sqrt{26}\ units[/tex]

To find out the perimeter of the rhombus multiply the length side by 4

f(g(x))=(x-2)^2 - 7

(x-2)(x-2) - 7

x^2-2x-2x+4-7

x^2-4x-3

g(f(x))=x^2-2-7

x^2-9

(x+3)(x-3)

Step-by-step explanation:

To evaluate functions, you substitute x with the given value in the function and perform the calculation. For example, evaluating f(3) for the function f(x)=x^2-7 gives f(3)=2, while evaluating g(3) for the function g(x)=x-2 gives g(3)=1.

The functions given are f(x)=x^2-7 and g(x)=x-2. To evaluate these functions, we substitute a value for x into the function and perform the calculation. For example, if we want to evaluate f(3), we replace x in the function f(x) with 3.

So for f(3)=3^2-7, we do the following: f(3)=9-7=2.

For g(3), we substitute x in the function g(x) with 3: g(3)=3-2=1

It's important to note that the value you're evaluating might change depending on the question, but this is the basic process for evaluating a function at a given value or values.
