Brad puts an equal amount of money in his savings account once a month. He started with $27. The next month, he had $44 in his account. Two months after that, he had $78 in his account. How much money will Brad have in his account after 6 months?

So firstly, we need to find how much the entire trip will cost. To do this, add the product of 16 and 35 (since tickets are 35 per student, and there are 16 students) with 960:

[tex](35*16)+960\\560+960\\\\\$ 1520[/tex]

The total cost of the trip is $1520. Next, we know that the sweatshirts will be making a profit of $19 per article sold so divide 1520 by 19:

[tex]1520\div 19=80[/tex]

The students need to sell 80 sweatshirts total to get enough money for the trip. Now, to know how many sweatshirts each student needs to sell individually, divide 80 by 16 (since there are 16 students):

[tex]80\div 16=5[/tex]

In short, each student must sell 5 sweatshirts to pay for the entire trip.

Answer

Given the statement: In parallelogram ABCD, diagonals AC and BD intersects at point E.

Given that ABCD is a parallelogram.  

As, we know that in a parallelogram diagonals bisect each other.

Since AC and BD intersect at E, and we get E is the mid point of both diagonals AC and BD.

⇒ BE = DE                  .....[1]

Substitute the given values of [tex]BE = 2x^2 -3x[/tex] and [tex]DE = x^2+10[/tex] in [1] we have;

[tex]2x^2-3x = x^2+10[/tex]

Subtract [tex]x^2[/tex] on both sides we get;

[tex]2x^2-3x-x^2 = x^2+10-x^2[/tex]

Simplify:

[tex]x^2-3x =10[/tex]

Subtract 10 on both sides we get;

[tex]x^2-3x-10 =0[/tex]

or

[tex]x^2-5x+2x-10 =0[/tex]

[tex]x(x-5)+2(x-5)=0[/tex]

[tex](x-5)(x+2)=0[/tex]

equate these factors equal to zero we get;

(x-5) = 0  and (x+2) = 0

we have;

x = 5 and x = -2

Since, x cannot be negative.

So, x =5

[tex]BE = DE = x^2+10 = (5)^2+10 = 25+10 = 35 units[/tex]

Diagonals BD = BE + DE = 35 + 35 =70 units.

Therefore, the value of BD = 70 units.

Answer:

(D)68

Step-by-step explanation:

If 1 litre =4.23 cups

and 1 cup = 8 ounces

Therefore: 1 litre = 4.23 X 8 Ounces = 33.84 Ounces

2 litres = 2 x 33.84 Ounces

           =67.68 Ounces

           =68 Ounces (To the nearest whole number)

The number of ounces in 2 liters will be 68 ounces. Thus, the correct option is D.

Given that:

1 liter = 4.23 cups

1 cup = 8 ounces

Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.

The number of cups in 2 liters is calculated as,

⇒ 2 x 4.23

⇒ 8.46 cups

The number of ounces in 8.46 cups is calculated as,

⇒ 8.46 x 8

⇒ 67.68 or 68 ounces

Thus, the correct option is D.

Answer:

x = 5

Step-by-step explanation:

in ΔABC , AB = BC , hence triangle is isosceles, thus

∠A = ∠C = 73° ( base angles are equal )

the sum of the 3 angles in a triangle = 180°

subtract the sum of the base angles from 180 for ∠B

∠B = 180° - (73 + 73)° = 34°

⇒ 6x + 4 = 34 ( subtract 4 from both sides )

6x = 30 ( divide both sides by 6 )

x = 5

The correct answer is A.

Answer:

total earning is  $64.80

Step-by-step explanation:

Price of one work = $18.00

Payment  by owner = 1/4 of $18.00

                                 = 18/4

                                  = $4.50

Earning by tip =  20% of $18.00 =  20/100 x18 = 3.60

Total earning from one work   =   $4.50+$3.60

                                                = $ 8.10

Answer:     Arithmetic , Divergent

Step-by-step explanation:

Given sequence is  

{aₙ} =  {  4 , 10/3  , 8/ 3 , 2 , . . .   }

To check whether the sequence is geometric or not , we divide second term by first term  to find the common ratio . Then we again divide third term by second term to get common ratio .

The common ratio we get would same , then it is geometric .

         10/3               10            5

r₁  =  -----------  =     ------    =   ------

             4                12             6

        8/3                8                  3                4

r₂=   ----------   =  ----------  *   ------------   =     -----

           10/ 3             3              10                  5

Thus the common ratio are not same . So the sequence is not geometric .

Now we check for arithmetic .

We take difference of second and first term and then difference of third and second term . If it will be same then it is arithmetic . This is called common difference , d .

             10                       -  2

d₁   =    ------     - 4   =       -------

              3                          3

                8            10             - 2

d₂   =    ------    -   --------    =   ---------

               3             3                 3

Thus the common difference is same .

So the given sequence is arithmetic .

To find whether it is convergent or divergent , we need to write sum of n terms first .

Formula for finding sum of n terms of arithmetic sequence is

            n

sₙ =     -----  [ 2a + ( n - 1 ) d]

             2

We have a = 4 , d = - 2/3 .

Plug  in this formula we get

              n                                                    n                2             2

sₙ  =     ------- [ 2 * 4 + ( n - 1 ) ( -2/3) ]  =     ------ [  8 -   -----  n  +   ------  ]

              2                                                    2                3               3

           n          26              2

sₙ  =   ------  [    ------    -    ------- n  ]

           2           3                3

To check whether it is convergent or divergent , we take limit sₙ approaches to infinity .

                               n       26       2

lim   sₙ   =     lim    { ---   [  ---  -  ------ n ] } =     - ∞

n → ∞           n→∞      2        3       3

As the sequence diverge , thus the series is divergent .

Thus given series is arithmetic , divergent .

Second is the  correct option .

Answer:

C = $100+$35x

Step-by-step explanation:

Given :

A company spends $100 per day on fixed expenses such as electricity, rent, and the like.

It also spends $35 per day on each employee working that day.

To Find : a linear equation relating the total daily cost, C, with the number of employees working on any particular day, x.

Solution :

A company spend  $100 per day on fixed expenses

No. of employees working on a particular day = x

Company spend on each employee  per day = $35

It spends on x employee = $35x

Since total daily cost = C

Thus C = $100+$35x

Hence , a linear equation relating the total daily cost, C, with the number of employees working on any particular day, x. :  C = $100+$35x

Step-by-step explanation:

As given

The art club at a school raised $248 at a car wash.

They spent $206 to set up an art show, and raised $316 at the art show by selling artwork the members had made.

Than

Money club have after the show =  school raised money at a car wash +  Raised money at the art show  -  spent money to set up an art show.

Money club have after the show =  248 +  316 - 206

Money club have after the show =  564 - 206

Money club have after the show =  $358

Therefore  money  club have after the show is  $358 .

Answer:

It is 358.

Step-by-step explanation:

The club started with $248, and then spent $206.

First, check the difference between each term:

2 → 5 = +3

5 → 10 = +5

10 → 17 = +7

17 → 26 = +9

Since the difference (d) is not the same, this is not an arithmetic sequence.

Now, check the second tier {3, 5, 7, 9}

3 → 5 = 2

5 → 7 = 2

7 → 9 = 2

The difference (d) of the second tier is the same, so it is an exponential sequence.

Answer:

2, and 10

Step-by-step explanation:

Let's work through each one.

First, plug -10 into the equation:

-10² + 20 = 12 x -10?

-10² = 100

100 + 20 = 120

12 x -10 = -120

120 = -120?    False!

But, using these same calculations, we can see that 10 is a correct answer.

Because everything's the same up to 12 x 10 = 120.

120 = 120

Same with 2 and -2

-2 does not work, but 2 does.

2² + 20 = 12 x 2?

4 + 20 = 24?

24 = 24?    True!

The solution of the given quadratic equation is x = 2 and x = 10.

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared.

Given a quadratic equation, x²+20 = -12x

x²-12x+20 = 0

On factorizing the equation,

x²-10x-2x+20 = 0

x(x-10)-2(x-10) = 0

(x-10)(x-2) = 0

x = 10 or x = 2

Hence, the solution of the given quadratic equation is x = 2 and x = 10.
