Answer:

25x + 5y + z cents

Step-by-step explanation:

1 quarter is worth 25 cents.

1 nickel is worth 5 cents.

1 penny is worth 1 cent.

Therefore, x quarters, y nickels and x pennies will be worth:

(x * 25) + (y * 5) + (z * 1)

= 25x + 5y + z cents

Answer:

The system of equations is consistent and independent

Step-by-step explanation:

Given system of equations :

[tex]y=x+4\\y= -x-4[/tex]

Consistent : For a two variable system of equations to be consistent the lines formed by the equations have to meet at some point or they have to be parallel.

Inconsistent :If the system of equations is not consistent then it is inconsistent.

Dependent:A dependent system of equations has infinite solutions

Independent :An independent system has a single solution.

Plot the lines on graph

y=x+4 --- Blue line

y=-x+4 ---- Green line

Refer the attached graph

The lines formed by the equations intersect at one point

So the lines are consistent

Now the given system of equations has single solution . So, it is independent

So, Option C is true

Hence The system of equations is consistent and independent

Answer:

Step-by-step explanation:

Mathematically, the probability of drawing a pure cotton shirt = number of cotton shirts/Total number of shirts

Firstly , we are to calculate the number of cotton shirts after the addition of the new four

Thus;

Total number of shirts is now = 20+4 = 24

Let the number of cotton shirts be x after the addition

3/4 = x/24

24 * 3 = 4x

x = 72/4

x = 18

Now kindly recall that q became x only because we added 4 new extra cotton shirts

So the number of cotton shirts before the addition = 18-4 = 14

Answer:

5/8

Step-by-step explanation:

Step 1: Add

1/16 + 9/16 = 10/16

Step 2: Divide both numerator and denominator by 2

10/2 = 5

16/ 2 = 8

Our answer is 5/8!

Answer:

[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

1 + 9 = 10

same denominator so it stays the same

[tex]\frac{10}{16}[/tex] ÷ [tex]\frac{2}{2} = \frac{5}{8}[/tex]

Answer:

[tex] = ( - \frac{2}{3} \times \frac{3}{4}) \times ( - 1) [/tex]

[tex] = \frac{( - 2) \times ( - 1)}{4} [/tex]

[tex] = \frac{ + 2}{4} [/tex]

Answer:

a(8) = -49152

Step-by-step explanation:

Step 1: Find r

-12/3 = 4

Step 2: Write geometric explicit formula

[tex]a_{n} = 3(4)^{n-1}[/tex]

Step 3: Plug in 8th term for n

[tex]a_{8} = 3(4)^{7}[/tex]

a(8) = -49152

Alternatively you can find r then multiply 3 by -4 8 times.

Answer:

Either £16 or £26.32 depending on what you meant in the question

Step-by-step explanation:

I'm going to answer the question in 2 ways, since I'm not sure if you mean £14 or 14%

If its £14, then the original price is 30-14 = £16

If its 14% then that means after the increase, the shirt will be 100%+14% of the original price or 114% of the original price.

This means that

£30 = 114%

To make it easier, reduce the 114% to 1 %

1% = 30/114

1% = £0.26316

100% = £26.32 (rounded to 2 decimal places)

Therefore the original price was £26.32

Answer:

252 bags of maize

Step-by-step explanation:

From the question, we are told that a farmer harvested maize

In the year 2012 = 144 bags of maize

In the year 2013(following year) the harvest decreased in the ratio 3:4

This means

3:4 = 2013: 2012.

Where number of bags harvested in 2013 = unknown = x

3/4 = x/ 144

Cross multiply 4x = 3 × 144

x = 3 × 144/ 4

× = 108

This means 108 bags of maize was harvested in 2013

The total number of bags harvested is = 108 + 144

= 252 bags of maize.

Answer:

15.5833333333 or 15 7/12

Step-by-step explanation:

When you less simplify 1/4 and 1/3, we get 3/12 and 4/12. So, when you add those two fractions, you get 7/12. Now, we add 12 and 3 to get 15. Hence,

the two fractions given equal to 15 7/12.

Answer: i) 12.5%       ii) 87.5%        iii) 23.4%

Step-by-step explanation:

There are two die, each with 8 sides so the total number of outcomes is 8²

i) Product is a prime number --> 2, 3, 5, 7

Since it is a prime we only have the option of one die being a 1 and the other being the prime number.

So possible successful outcomes is: (1, 2), (1, 3), (1, 5), (1, 7), (7, 1), (5, 1), (3, 1), and (2, 1) = 8 options.

[tex]\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{8}{8^2}=\dfrac{1}{8}=\large\boxed{12.5\%}[/tex]

ii) Not a perfect square.  Let's find the probability that it IS a perfect square and subtract that value from the total (64).

Product IS a perfect square --> 1, 4, 9, 16, 25, 36, 49, 64

Possible successful outcomes of a perfect square: (1, 1) (2, 2), (3, 3), (4, 4), (5, 5), (6, 6), (7, 7), (8, 8) = 8 options.

Product is NOT a perfect square = 64 - 8 = 56 options

[tex]\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{56}{8^2}=\dfrac{7}{8}=\large\boxed{87.5\%}[/tex]

iii) Product is a multiple of 5 --> 5, 10, 15, 20, ,25, 30, 35, 40,

Possible successful outcomes of a multiple of 5: (1, 5), (2, 5), (3, 5), (4, 5), (5, 5), (6, 5), (7,5), (8, 5), (5, 8), (5, 7), (5, 6), (5, 4), (5, 3), (5, 2), (5, 1) = 15 options

[tex]\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{15}{8^2}=\dfrac{15}{64}=\large\boxed{23.4\%}[/tex]

Answer:

d. The two triangles are not congruent because dilation is not a rigid motion.

Step-by-step explanation:

Triangle ABC is dilated about the origin b a factor of 2. It is then reflected and translated to form Triangle XYZ.

The new triangle formed is not congruent to ABC because the image is not the same size as the pre-image. It is only rigid transformations that preserve length, however dilation is not a rigid transformation.

Answer:

8.25

Step-by-step explanation:

To solve, you need to create a system of equations.  You will need two variables since you have two numbers.  Create your equations based on the descriptions given in the problem.

The difference of two numbers is 4.

x - y = 4

The sum of the two number is -7.

x + y = -7

Your system of equations is

x - y = 4

x + y = -7

You can solve systems of equations through either substitution or elimination.  You will get the right answer either way.  I will use substitution since that is my preference.

Rearrange the first equation so that it is equal to x.

x - y = 4

x = 4 + y

Plug this x-value into the x in the second equation.  Solve for y.

x + y = -7

(4 + y) + y = -7

4 + 2y = -7

2y = -11

y = -11/2

Use the y-value to solve for x.  You can plug it into either equation and get the right answer.  I will use the first equation.

x - y = 4

x - (-11/2) = 4

x + 11/2 = 4

x = -3/2

Now you have both of the numbers.  Multiply to find the product.

-11/2 × -3/2 = 33/4 = 8.25

The answer is 8.25.

Answer: The answer is provided below

Step-by-step explanation:

A price markdown is a reduction that is deliberate when selling a product. From the question, we are informed that a video game that usually costs $30.65 is marked down 60%.

The find the new price of the video game, we have to subtract the amount reduced from the original price. The amount reduced is:

= 60% of $30.65

= 60/100 × $30.65

= 0.6 × $30.65

= $18.39

The new selling price = $30.65 - $18.39

= $12.26

The error that Kelvin made when he determined that the new price of the game would be $18.39 was that he didn't subtract the value from the original price of the video game.

Answer:

Divide by two is the term to term rule

Step-by-step explanation:

64/2=32

32/2=16

16/2=8

8/2=4

the term-to-term rule for this sequence is to multiply each term by 1/2 to obtain the next term.

The given sequence 64, 32, 16, 8, 4 is a geometric sequence with a common ratio of 1/2.

To find the term-to-term rule for a geometric sequence, we multiply each term by the common ratio to get the next term. In this case, the common ratio is 1/2.

The term-to-term rule for this sequence is:

Multiply each term by 1/2 to get the next term:

64 × 1/2 = 32

32 × 1/2 = 16

16 × 1/2 = 8

8 × 1/2 = 4

Therefore, the term-to-term rule for this sequence is to multiply each term by 1/2 to obtain the next term.

Answer:

8 th term

Step-by-step explanation:

Continuing the sequence from the last term given (term 4 )

a₅ = 0.5 × 28.5 - 2 = 14.25 - 2 = 12.25

a₆ = 0.5 × 12.25 - 2 = 6.125 - 2 = 4.125

a₇ = 0.5 × 4.125 - 2 = 2.125

a₈ = 0.5 × 2.125 - 2 = 1.0625 - 2 = - 0.9375 ← negative

The first term to be negative is term 8
