A party host is making identical party bags for guests using 44 bottles of bubbles, 89 stickers, and 55 pencils. What is the greatest number of identical party bags the host can make with the least amount of items leftover? Describe the contents of each bag.

Answers

Answer: 11 party bags with 1 sticker leftover

Each bag contains 4 bubbles, 8 stickers, and 5 pencils.

Step-by-step explanation:

Find the GCF of 44 (bubbles), 89 (stickers), and 55 (pencils)

44: 2 x 2 x 11

89: prime so choose 88 with 1 leftover

88: 2 x 2 x 2 x 11

55: 5 x 11

GCF = 11

Disregard the GCF to see how many of that item should go in each bag.

Bubbles: 2 x 2

Stickers: 2 x 2 x 2

What are the values of m and n in the matrix addition below?

Answers

ANSWER

The correct answer is [tex]m=45,n=12[/tex].

EXPLANATION

We were given the matrix equation;

[tex]\left[\begin{array}{cc}n-1&6\\-19&m+3\end{array}\right] +\left[\begin{array}{cc}-1&0\\16&-8\end{array}\right] =\left[\begin{array}{cc}10&6\\-3&40\end{array}\right][/tex].


We must first simplify the Left Hand Side of the equation by adding corresponding entries.


[tex]\left[\begin{array}{cc}n-1+-1&6+0\\-19+16&m+3-8\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right][/tex].


That is;


[tex]\left[\begin{array}{cc}n-2&6\\-3&m-5\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right][/tex].

Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.


This implies that;


[tex]n-2=10[/tex]


We got this equation from row one-column one entry of both matrices.


[tex]n=12[/tex]


Also, the row three-column three entries of both matrices will give us the equation;


[tex]m-5=40[/tex]


[tex]m=45[/tex]


Hence the correct answer is [tex]m=45,n=12[/tex].

As a farmer, one of your responsibilities is to plow the field to prepare it for planting. On day 1, you plowed of the field. On day 2, you plowed of the field. How much more of the field did you plow on day 1 than on day 2?

Answers

Answer:

1/2 more then day 2.

Step-by-step explanation:


Final answer:

The difference in the amount of field plowed on day 1 compared to day 2 is 1/4, assuming day 1 was ½ and day 2 was ¼ of the field.

Explanation:

To calculate how much more of the field was plowed on day 1 than on day 2, we need to subtract the fractions that represent the part of the field plowed on each day. However, you did not specify the fractions, so I will assume you meant to say ½ of the field was plowed on day 1 and ¼ of the field on day 2. Thus, the difference can be calculated as follows:

Calculate the difference in fractions: ½ - ¼.Find a common denominator for the two fractions, which is 4 in this case.Convert both fractions to have the common denominator: ½ = 2/4 and ¼ remains the same.Subtract the numerators: 2 - 1 = 1.Write the result as a fraction with the common denominator: 1/4.

Therefore, you plowed 1/4 more of the field on day 1 than you did on day 2.

Step-by-step explanation

Given:-

Cat food ate by one cat = 1/4 cup

Cat food ate by five cats =[tex]5\times \frac{1}{4} \text{ [Multiplying both sides with 5 ]}\\\\=\frac{5}{4}=\frac{4+1}{4}=\frac{4}{4}+\frac{1}{4}=1+\frac{1}{4}[/tex]=1 and 1/4 cup.

You and your friend are having a race, but since you are faster than him, you decide to give him a head start. He starts 10m in front of the starting line while you start on the starting line. You run at 6 meters/second, while your friend runs at 5.5 meters/second. After how many seconds will you and your friend be same distance from the starting line? seconds months

Answers

Answer:

20 seconds

Step-by-step explanation:

Your friend starts 10 meters in front of the starting line.

You start from the starting line.

You run at 6 meters/ second.

Your friend runs at 5.5 meters/second.

You and your friend will be at the same distance from the starting line only when you are able to catch your friend.

The relative speed between you two is the difference in your speed and your friend's speed that is:

[tex]6-5.5=0.5m/s[/tex]

So to cover 10 meters of separation at the speed of 0.5 meter/second it will take:

[tex]t=\frac{10}{0.5}= \frac{100}{5}=20s[/tex]

So it will take 20 seconds for you and your friend to be at the same distance from the starting line.  

Answer:

20 seconds is correct.

A toy jeep is 12 1/2 inches long while an actual Jeep measures 18 3/4 ft long what is the value of the ratio length of a toy Jeep to the length of a actual Jeep

Answers

The length of toy jeep = [tex]12 \frac{1}{2}[/tex]

= [tex]\frac{25}{2}[/tex] inches

The length of actual Jeep = [tex]18 \frac{3}{4}[/tex] feet

We have to find the ratio length of a toy jeep to the length of actual jeep.

Firstly, we will make the dimensions of the both the given lengths same.

As 1 foot = 12 inches

[tex]18 \frac{3}{4}[/tex] feet = [tex]18 \frac{3}{4} \times 12[/tex] inches

=[tex]\frac{75 \times 12}{4}[/tex]

= 225 inches

So, the ratio length of toy jeep to actual jeep

= [tex]\frac{25}{2} \div 225[/tex]

= [tex]\frac{25}{2} \times \frac{1}{225}[/tex]

= [tex]\frac{1}{18}[/tex]

= 1:18

So, the ratio length of a toy Jeep to the length of a actual Jeep is 1:18.

Length of toy jeep = [tex]12\frac{1}{2}=\frac{25}{2}[/tex] inches

Length of actual jeep = [tex]18\frac{3}{4}=\frac{75}{4}[/tex] feet

Now to find the ratio between the two, we must convert both of them in same units. So, lets convert the actual jeep length in feet to inches.

1 feet = 12 inches.

So, [tex]\frac{75}{4}[/tex] feet = [tex]\frac{75}{4}\times12=225[/tex] inches

Ratio of length of toy jeep to actual jeep will be =

[tex]\frac{\frac{25}{2}}{225}[/tex]

[tex]\frac{25}{2\times225}[/tex]

[tex]\frac{25}{450}[/tex] = [tex]\frac{5}{90}[/tex]

ratio is : [tex]\frac{1}{18}[/tex] or 1:18

Which statement correctly describes the relationship between △ABC and △A′B′C′ ?


A. △ABC is congruent to △A′B′C′ because the rules represent a reflection followed by a rotation, which is a sequence of rigid motions.

B. △ABC is congruent to △A′B′C′ because the rules represent a rotation followed by a reflection, which is a sequence of rigid motions.

C. △ABC is not congruent to △A′B′C′ because the rules do not represent a sequence of rigid motions.

Answer:

B. △ABC is congruent to △A′B′C′ because the rules represent a rotation followed by a reflection, which is a sequence of rigid motions.

Step-by-step explanation:

I just took the test, good luck! Have a wonderful day! :)

Transformation involves changing the position of a shape.

The correct statement is: (b) △ABC is congruent to △A′B′C′ because the rules represent a rotation followed by a reflection, which is a sequence of rigid motions.

The transformation rule is given as:

[tex]\mathbf{(x,y) \to (-x,-y)}[/tex], then:

[tex]\mathbf{(x,y) \to (x,-y)}[/tex]

The first transformation [tex]\mathbf{(x,y) \to (-x,-y)}[/tex] is 180 degrees rotation across the originThe second transformation [tex]\mathbf{(x,y) \to (x,-y)}[/tex] is a reflection across the x-axis

Rotation and reflection are both rigid transformation.

Hence, the correct option is (b):

Sam initially invested $4,500 into a savings account that offers an interest rate of 3% each year. He wants to determine the number of years, t, for which the account will have less than or equal to $7,020.

Answers

Every year, Sam will have 103% of the amount from the previous year.

A bag of marbles contains 7 red, 5 blue, 4 red, and 2 yellow marbles. Jon selects a marble, replaces it, then selects another marble. What is the probability that Jon selects a red marble and then a yellow marble?

Question 2 options:

about 0.778 or 77.8%


0.5 or 50%


about 0.043 or 4.3%


0.25 or 25%

Answers

[tex]|\Omega|=18^2=324\\|A|=7\cdot2=14\\\\P(A)=\dfrac{14}{324}=\dfrac{7}{162}\approx0.043(=4.3\%)[/tex]

First, we find the total number of marbles.

We add up the red, blue, and yellow marbles:

The number of red marbles is 7 + 4 which equals to 11.

The number of blue marbles is 5.

The number of yellow marbles is 2.

To find the total number, we add these numbers together: 11 (red) + 5 (blue) + 2 (yellow) = 18. So, the total number of marbles is 18.

Second, we find the probability of each event - that is, picking a red marble and then a yellow marble.

Probability is the number of desired outcomes divided by the total number of possible outcomes.

The probability of picking a red marble, denoted as P(red) is the number of red marbles divided by the total number of marbles. So, P(red) = 11 / 18 which is about 0.611 or 61.1%.

The probability of picking a yellow marble, denoted as P(yellow) is the number of yellow marbles divided by the total number of marbles. So, P(yellow) = 2 / 18 which is about 0.111 or 11.1%.

Finally, we can find the answer to our question: What is the probability that Jon selects a red marble and then a yellow marble?

Because these are independent events (selecting a red marble does not affect the chance of selecting a yellow marble next), we can use the multiplication rule of probability to find the overall probability.

The multiplication rule states that the probability of two independent events both happening is the product of their individual probabilities. So the probability of picking a red marble and then a yellow marble, denoted as P(red and yellow), is P(red) * P(yellow).

P(red and yellow) = P(red) * P(yellow) = 0.611 * 0.111 which results in about 0.0679 or 6.8%.

So, the closest option is about 0.043 or 4.3% which seems to be incorrect as our calculated probability is different. There might be a mistake in the question or the provided options.

y = (x - 3)2 - 1

y = (x + 3)2 - 1

y = (x - 4)2 - 2

y = (x - 4)2 + 8

Answers

For this case we have:

The equation in vertex form of the parabola is given by:

[tex]y = a (x-h) ^ 2 + k\\[/tex]

The vertex is (h, k) and is given by the highest or lowest point of the parabola, in this case it is observed that it is [tex](h, k) = (- 3, -1)\\[/tex]

Thus, the equation is given by:

[tex]y = a (x - (- 3)) ^ 2 + (- 1)\\\\y = a (x + 3) ^ 2-1\\[/tex]

We look for the value of a, substituting a point of the parabola in the equation in the form of vertex, we will take the point [tex](x, y) = (0,8)\\[/tex]

Substituting we have:

[tex]8 = a (0 - (- 3)) ^ 2 + (- 1)\\\\8 = a (0 + 3) ^ 2-1\\\\8 = a (3) ^ 2-1\\[/tex]

[tex]8 = 9a-1\\\\8 + 1 = 9a\\\\9 = 9a\\[/tex]

[tex]a = \frac{9}{9}\\\\a = 1\\[/tex]
