Step-by-step explanation:

Company 1: 3.25x + 26

Company 2: 3.50x + 24

3.50x + 24 = 3.25x + 26

0.25x  +24 = 26        subtracted 3.25x from both sides

0.25x = 2            subtracted 24 from both sides

x = 8               divided both sides by 0.25

Check:

Company 1: 3.25x + 26  =  3.25(8) + 26  = $52

Company 2: 3.50x + 24  = 3.50(8) + 24  = $52

Answer:  The required ratio in simplest form is 7 : 5 : 8.

Step-by-step explanation:  Given that in a fruit punch drink, the 3 ingredients are apple juice orange juice and cranberry juice. [tex]\frac{1}{4}[/tex] of the drink is apple juice and [tex]\frac{2}{5}[/tex] is orange juice.

We are to find  the ratio of cranberry juice to apple juice to orange juice in its simplest form.

Let x, y and z be the fractions of the cranberry juice, apple juice and orange juice in the fruit punch drink.

Then, according to the given information, we have

[tex]y=\dfrac{1}{4},~~z=\dfrac{2}{5}.[/tex]

Now,

[tex]x+y+z=1\\\\\\\Rightarrow x+\dfrac{1}{4}+\dfrac{2}{5}=1\\\\\\\Rightarrow x=1-\dfrac{1}{4}-\dfrac{2}{5}\\\\\\\Rightarrow x=\dfrac{20-5-8}{20}\\\\\\\Rightarrow x=\dfrac{7}{20}.[/tex]

Therefore, the ratio of cranberry juice to apple juice to orange juice is given by

[tex]x:y:z\\\\\\=\dfrac{7}{20}:\dfrac{1}{4}:\dfrac{2}{5}\\\\\\=\dfrac{7}{20}:\dfrac{5}{20}:\dfrac{8}{20}\\\\=7:5:8.[/tex]

Thus, the required ratio in simplest form is 7 : 5 : 8.

Since there are 55 candies in the bag, and there are 20% of blue candies, it would look like this:

55 x 0.20 = 11

Now that we have 11, you multiply it by the damage coating, so

11 x 0.10 = 1.1

Approximately 1 blue chocolate had a damaged candy coating from Kathleen's bag since 20% of the 55 chocolates were blue (resulting in 11 blue chocolates), and 10% of these were damaged (resulting in approximately 1 chocolate).

Kathleen has a bag with a total of 55 candy-coated chocolates. Since 20% of these chocolates are blue, we first need to compute the number of blue chocolates. 20% of 55 translates to 0.20 × 55, which gives us 11 blue chocolates.

Of these blue chocolates, 10% had a damaged candy coating. To find out how many are damaged, we calculate 10% of 11, which is 0.10 × 11. This calculation results in 1.1, which we round to approximately 1 since we cannot have a fraction of a chocolate. Therefore, about 1 of the blue chocolates had a damaged coating.

Answer:

120 people voted against building the new basketball court.

Step-by-step explanation:

if you divide 200 by 100 then you know how many people equal 1 percent of the 200. knowing that for every 2 people they are equal to 1 percent. so if you do 100 -40 you get 60. the 100 represents the 100 percent and you subtract 40 because these are the people who are voting for the basketball court. The 60 represents the percent of people who are voting against building the basketball court. then you multiply 60 by 2 and you get 120.

It will take 15 weeks for Nancy’s account to have twice as much money as Fred's.

We are looking for the number of weeks it will take for Nancy’s account to have twice as much money as Fred’s account. Both Fred and Nancy start with $15. Each week, Nancy adds $3 to her account and Fred adds $1 to his account.

So we have to solve the equation: 15 + 3x = 2 * (15 + x), where x is the number of weeks. Simplifying the equation gives us x = 15 weeks. Thus, it will take 15 weeks for Nancy’s account to have twice as much money as Fred’s account.

Final answer:

To model the cost of purchasing concert tickets where each ticket is $44 and there's a fixed handling fee of $12, the equation is T = 44n + 12, with T representing the total cost and n the number of tickets.

Explanation:

The question deals with constructing a mathematical model for the situation where an online ticket seller charges a fixed price for a concert ticket plus a handling fee. Here, the unknown variable is the total cost (T) for purchasing a certain number of tickets (n). The fixed price for each ticket is $44, and there is a flat handling fee of $12 regardless of the number of tickets purchased. Therefore, the equation to model the total cost would be:

T = 44n + 12

This equation clearly defines how the total cost is determined by the number of tickets purchased, with n representing the number of tickets and T the total cost.

Answer:

TRUE

Step-by-step explanation:

Given that line segment JK and LM are parallel. From picture we see that LK is transversal line.

We know that corresponding angles formed by transversal line are congruent.

Hence ∠JKL = ∠ MLK ...(i)

Now consider triangles JKL and MLK

JK = LM  {Given}

∠JKL = ∠ MLK { Using (i) }

KL = KL  {common sides}

Hence by SAS property of congruency of triangles, ΔJKL and ΔMLK are congurent.

Hence given statement is TRUE.

The statement that if JK and LM are congruent and parallel, then angles JKL and MLK are congruent is false. Congruency of angles depends on more than just the congruency and parallelism of two lines.

In the field of geometry, just because two lines are congruent and parallel, this does not necessarily mean that the angles formed by the intersection of the lines with a third line are congruent. The statement 'If JK and LM are congruent and parallel, then JKL and MLK are congruent' is false. Congruency of angles JKL and MLK depends on the relationship between the two other sides of the angles, not solely the lines JK and LM. Therefore, for the angles to be congruent, additional conditions besides the congruency and parallelism of JK and LM must be satisfied.

Answer:

The product of the 5^56 x 5^22 x 5^-96= 1/5^18.

Step-by-step explanation:

The problem represents the Laws of Exponents.  When you multiply using exponents, you keep the base and add the exponents.  In this case, the base is 5 and our exponents are 56 + 22 + -96.  We we add these three integers, we get a total of -18, which gives us a base of 5 and exponent of -18 or 5^-18.  We don't typically have negative exponents, so our next rule to follow is when you have negative exponents, you flip the base, or make it a fraction, and make the exponent positive.  This gives us a final answer of 1/5^18.  

The value of the product is 5^56 × 5^22 × 5^(-96) is 1/(5^18)

         While multiplying two exponents with the same base then we should add the powers to get the result.

            Example: x^a + x^b = x^(a+b)

              5^56 × 5^22 × 5^-96 = 5^(56+22+(-96))

                                                    = 5^(-18)

       A non-zero real number with negative power is written as

    1/ (non-zero number with the positive power of the same number).

     Example:  x^(-2) = 1/(x^2)

  So, we can write 5^(-18) as 1/5^(18).

   Hence,

       5^56 × 5^22 × 5^-96 = 1/5^(18).

Answer:

t=4 seconds

Step-by-step explanation:

The equation given to us is

d=30 + vt + 4t²

d=126 feet

v= 8 ft per second

to find t =?

Now putting the values in the above equation gives

126 = 30 + 8t + 4t²

126 - 30 = 8t + 4t²

96 = 8t + 4t²

Dividing the whole equation by 4

[tex]\frac{96}{4}=\frac{8t}{4}+\frac{4t^{2} }{4}[/tex]

it will become

24 = 2t + t²

taking 24 to other sides of equality

0 = 2t + t² -24

t²+2t-24=0

Now we will do mid term breaking of the eqaution

t²+6t-4t-24=0

taking common from the equation

t(t+6)-4(t+6)=0

(t+6)(t-4)=0

so it becomes

t+6 = 0                  or   t-4 =0

t =-6                       or   t = 4 seconds

as time can not be negative

so t=4 seconds
